ASTRO Pushes Return to Direct Supervision in RT: Needed or ‘Babysitting’?
Although serious errors during virtual supervision are rare, ASTRO said radiation treatments (RT) should be done with a radiation oncologist on site to ensure high-quality care. But some radiation oncologists do not agree with the proposal to move back to direct in-person supervision only.
Changes to Direct Supervision
Most radiation oncology treatments are delivered in an outpatient setting under a physician’s direction and control.
During the COVID-19 pandemic when social distancing mandates were in place, CMS temporarily changed the definition of “direct supervision” to include telehealth, specifying that a physician must be immediately available to assist and direct a procedure virtually using real-time audio and video. In other words, a physician did not need to be physically present in the room when the treatment was being performed.
CMS has extended this rule until the end of 2024 and is considering making it a permanent change. In the Calendar Year (CY) 2024 Medicare Physician Fee Schedule (PFS) Final Rule, CMS asked for comments on whether to extend the rule.
“We received input from interested parties on potential patient safety or quality concerns when direct supervision occurs virtually, which we will consider for future rulemaking,” a CMS spokesperson told this news organization. “CMS is currently considering the best approach that will protect patient access and safety as well as quality of care and program integrity concerns following CY 2024.”
CMS also noted its concerns that an abrupt transition back to requiring a physician’s physical presence could interrupt care from practitioners who have established new patterns of practice with telehealth.
What Are ASTRO’s Concerns?
Late last month, ASTRO sent CMS a letter, asking the agency to change the rules back to direct in-person supervision for all radiation services, citing that virtual supervision jeopardizes patient safety and quality of care.
Jeff Michalski, MD, MBA, chair of the ASTRO Board of Directors, said in an interview that radiation oncologists should be physically present to supervise the treatments.
“ASTRO is concerned that blanket policies of general or virtual supervision could lead to patients not having direct, in-person access to their doctors’ care,” he said. “While serious errors are rare, real-world experiences of radiation oncologists across practice settings demonstrate how an in-person radiation oncology physician is best suited to ensure high-quality care.”
What Do Radiation Oncologists Think?
According to ASTRO, most radiation oncologists would agree that in-person supervision is best for patients.
But that might not be the case.
Radiation oncologists took to X (formerly Twitter) to voice their opinions about ASTRO’s letter.
Jason Beckta, MD, PhD, of Rutland Regional’s Foley Cancer Center, Vermont, said “the February 26th ASTRO letter reads like an Onion article.”
“I’m struggling to understand the Luddite-level myopia around this topic,” he said in another tweet. “Virtual direct/outpatient general supervision has done nothing but boost my productivity and in particular, face-to-face patient contact.”
Join Y. Luh, MD, with the Providence Medical Network in Eureka, California, said he understands the challenges faced by clinicians working in more isolated rural settings. “For them, it’s either having virtual supervision or closing the center,” Dr. Luh said.
“Virtual care is definitely at my clinic and is not only an option but is critical to my patients who are 2+ snowy, mountainous hours away,” Dr. Luh wrote. “But I’m still in the clinic directly supervising treatments.”
Sidney Roberts, MD, with the CHI St. Luke’s Health-Memorial, Texas, tweeted that supervision does require some face-to-face care but contended that “babysitting trained therapists for every routine treatment is a farce.”
Another issue Dr. Luh brought up is reimbursement for virtual supervision, noting that “the elephant in the room is whether that level of service should be reimbursed at the same rate. Reimbursement has not changed — but will it stay that way?”
ASTRO has acknowledged that radiation oncologists will have varying opinions and says it is working to balance these challenges.
CMS has not reached a decision on whether the change will be implemented permanently. The organization will assess concern, patient safety, and quality of care at the end of the year.

Does worsening metabolic syndrome increase the risk of developing cancer?
The conditions that comprise metabolic syndrome (high blood pressure, high blood sugar, increased abdominal adiposity, and high cholesterol and triglycerides) have been associated with an increased risk of diseases, including heart disease, stroke, and type 2 diabetes, wrote Li Deng, PhD, of Capital Medical University, Beijing, China, and colleagues.
A systematic review and meta-analysis published in Diabetes Care in 2012 showed an association between the presence of metabolic syndrome and an increased risk of various cancers including liver, bladder, pancreatic, breast, and colorectal.
More recently, a 2019 study published in Diabetes showed evidence of increased risk for certain cancers (pancreatic, kidney, uterine, cervical) but no increased risk for cancer overall.
However, the reasons for this association between metabolic syndrome and cancer remain unclear, and the effect of the fluctuating nature of metabolic syndrome over time on long-term cancer risk has not been explored, the researchers wrote.
What Does New Study Add to Other Research on Metabolic Syndrome and Cancer Risk?
In the new study, published in Cancer on March 11 (doi: 10.1002/cncr.35235), 44,115 adults in China were separated into four trajectories based on metabolic syndrome scores for the period from 2006 to 2010. The scores were based on clinical evidence of metabolic syndrome, defined using the International Diabetes Federation criteria of central obesity and the presence of at least two other factors including increased triglycerides, decreased HDL cholesterol, high blood pressure (or treatment for previously diagnosed hypertension), and increased fasting plasma glucose (or previous diagnosis of type 2 diabetes).
The average age of the participants was 49 years. The four trajectories of metabolic syndrome were low-stable (10.56% of participants), moderate-low (40.84%), moderate-high (41.46%), and elevated-increasing (7.14%), based on trends from the individuals’ initial physical exams on entering the study.
Over a median follow-up period of 9.4 years (from 2010 to 2021), 2,271 cancer diagnoses were reported in the study population. Those with an elevated-increasing metabolic syndrome trajectory had 1.3 times the risk of any cancer compared with those in the low-stable group. Risk for breast cancer, endometrial cancer, kidney cancer, colorectal cancer, and liver cancer in the highest trajectory group were 2.1, 3.3, 4.5, 2.5, and 1.6 times higher, respectively, compared to the lowest group. The increased risk in the elevated-trajectory group for all cancer types persisted when the low-stable, moderate-low, and moderate-high trajectory pattern groups were combined.
The researchers also examined the impact of chronic inflammation and found that individuals with persistently high metabolic syndrome scores and concurrent chronic inflammation had the highest risks of breast, endometrial, colon, and liver cancer. However, individuals with persistently high metabolic syndrome scores and no concurrent chronic inflammation had the highest risk of kidney cancer.
What Are the Limitations of This Research?
The researchers of the current study acknowledged the lack of information on other causes of cancer, including dietary habits, hepatitis C infection, and Helicobacter pylori infection. Other limitations include the focus only on individuals from a single community of mainly middle-aged men in China that may not generalize to other populations.
Also, the metabolic syndrome trajectories did not change much over time, which may be related to the short 4-year study period.
What Is the Takeaway Message for Clinical Practice?
The results suggest that monitoring and managing metabolic syndrome could help reduce cancer risk, the researchers concluded.
“This research suggests that proactive and continuous management of metabolic syndrome may serve as an essential strategy in preventing cancer,” senior author Han-Ping Shi, MD, PhD, of Capital Medical University in Beijing, said in a press release accompanying the study.
More research is needed to assess the impact of these interventions on cancer risk, he noted. However, the data from the current study can guide future research that may lead to more targeted treatments and more effective preventive strategies, he said in a statement.
The study was supported by the National Key Research and Development Program of China. The researchers had no financial conflicts to disclose.

Higher Prostate Cancer Rates Seen in Black Men, but Advanced Cases Similar to White Men
There was a substantial difference in prostate cancer diagnosis across ethnic groups: 25% of Black men with a raised PSA were diagnosed with prostate cancer within 1 year of being tested, compared with 20% of White men and 13% of Asian men, in the analysis of a large primary care cohort in the United Kingdom.
Incidence of advanced prostate cancer for Asian men with a raised PSA result was 4.5%, compared with 7.5% for White men and 7.0% for Black men.
Men included in the study were aged 40 and older and had no prior cancer diagnosis. Their ethnicity and PSA test result were logged in a national dataset between 2010 and 2017.
The study of more than 730,000 men, published in BMC Medicine, didn’t explore reasons for the differences, but experts offer their thoughts on what led to the findings and what these results imply.
Why the Higher Diagnosis Rates but Not More Advanced Disease in Black Men?
Lead author Liz Down, a graduate research assistant at the University of Exeter, Exeter, England, suggests the higher diagnosis rates but not more advanced disease in Black men may be linked to genetic variations.
Her team’s studies have shown that Black men in the United Kingdom and United States have higher levels of PSA. The PSA value is used to identify patients who might benefit from specialist investigation, and current guidelines in the UK and US don’t distinguish between ethnic groups.
As most men have slow-growing prostate cancer, this may lead to a disproportionately higher number of Black men being diagnosed with prostate cancer, she said.
“One possible interpretation,” Ms. Down notes, “is that prostate cancer follows a similar trajectory in Black and White men. What is different, however, is that Black men have higher PSA levels.”
As to why the advanced-cancer incidence is similar in Black and White patients in the study, Daniel George, MD, director of genitourinary oncology at Duke Cancer Institute in Durham, North Carolina, says it’s important to understand that the Black men in this study “are not necessarily representative of the Black population at large.”
In this study, “they’re a little bit more healthcare inclined,” Dr. George notes. The study population is actively seeking the PSA test. Their socioeconomic profile might be closer to their White counterparts’, and that may make results more similar, he said.
“It’s possible that because this is a screening and not just men coming in for symptoms or cause, that we’re not seeing as much advanced disease,” he continued.
Amar Kishan, MD, chief of the genitourinary oncology service at University of California Los Angeles (UCLA) Health, says the genomic factors and environmental stressors that lead to elevated PSA counts don’t necessarily translate into aggressiveness of disease.
Why do Different Races have Different Prostate Cancer Risk?
Dr. George points out that the study also highlights that Asian men were significantly less likely to be diagnosed with prostate cancer within 1 year of the test.
The reasons for differences in prostate risk by race are complex, he notes. There are some clues that biologic factors may be at work. For instance, early puberty has a link to prostate cancer as it does to breast cancer, and height is also associated with a greater risk of prostate cancer, Dr. George said.
It’s not necessarily a racial association but there are some biological factors associated with prostate cancer later in life, he explained. “These may be enriched in certain populations, including northern Europeans and patients with African ancestries.”
The study also notes that Black men are more likely to die from prostate cancer than are White men, and Asian men are less likely than White or Black men to die from it.
Ms. Down said the difference in prostate cancer mortality between Black vs White men, in particular, may be related to a number of factors, and age, and lifetime risk of prostate cancer may play a major role, at least in the UK.
Should There Be Different ‘Normal’ PSA Levels for Different Races?
Dr. George says there is likely a need to change the system because a PSA level in one race may not signal the same risk it does in another. So medicine probably needs to standardize what a “normal” PSA is by race, he says, adding that he is a coauthor of an upcoming paper regarding that issue.
The lowest instances of prostate cancer were in Asian patients so this isn’t just a Black and White issue, Dr. George notes. “Being able to establish benchmarks by race and ethnicity is something that is probably needed in the field,” he says.
Dr. Kishan, on the other hand, says data from this study are not enough to support differentiating PSA levels based on race. He noted a limitation of the study is that it was not able to calculate the false-negative rate of PSA tests.
What are the Implications for Treating and Screening for Prostate Cancer
Dr. Kishan says there may be a role for increased intensity of screening, whether at an earlier age or with different intervals, but prostate cancer treatment should not differ by race.
“Our prior study, as well as others,” he says, “have shown that when you balance Black and White patients for every factor that might impact prognosis other than race — such as age, disease aggressiveness, etc. — Black men actually tend to have better outcomes than White men. Thus, it would mean potentially overtreating (i.e., causing unnecessary side effects) to increase treatment intensity purely based on race with the available data.”
According to the paper, prostate cancer incidence in men with higher PSA levels increases with increasing age, even when using age-adjusted thresholds.
Dr. George says we know from this study and other studies as well that Black men are more likely to be diagnosed with prostate at a younger age. “Therefore, we probably need to be thinking about screening Black men starting at a younger age. These are the men who are most likely to benefit from an intervention — patients who have life expectancies of 20 years or more.”
What are the Downsides to Overdiagnosing Prostate Cancer in Men?
“It’s one of the biggest concerns that men have in proactively seeking healthcare,” Dr. George says. “They’re more likely to undergo treatment for this disease if they’re getting screened because (clinicians are) more likely to find it.”
Some of those men, he says, are going to undergo treatment for disease that won’t ultimately kill them, but may cause complications the men shouldn’t have had at all or otherwise may have had later.
“Overtreatment is a real concern. That’s why active surveillance is so important to minimize overtreatment of patients by finding out which cancers are low risk for progression and which are becoming more aggressive,” Dr. George says.
Authors of the study write that “the potential for overdiagnosis and the subsequent psychological and physical impact of diagnosis and treatment is an important consideration.”
All authors of the new paper received financial support from Cancer Research UK, the National Institute for Health and Care Research (NIHR), and the Higgins family for the submitted work.
Dr. George reports no relevant financial relationships.
Dr. Kishan reports consulting fees and speaking honoraria from Varian Medical Systems, Janssen, and Boston Scientific; research funding from PointBioPharma, Lantheus, and Janssen; and serving on advisory boards for Lantheus, Janssen and Boston Scientific.

The lowest instances of prostate cancer were in Asian patients so this isn’t just a Black and White issue, Dr. George notes. “Being able to establish benchmarks by race and ethnicity is something that is probably needed in the field,” he says.
Dr. Kishan, on the other hand, says data from this study are not enough to support differentiating PSA levels based on race. He noted a limitation of the study is that it was not able to calculate the false-negative rate of PSA tests.
What are the Implications for Treating and Screening for Prostate Cancer
Dr. Kishan says there may be a role for increased intensity of screening, whether at an earlier age or with different intervals, but prostate cancer treatment should not differ by race.
“Our prior study, as well as others,” he says, “have shown that when you balance Black and White patients for every factor that might impact prognosis other than race — such as age, disease aggressiveness, etc. — Black men actually tend to have better outcomes than White men. Thus, it would mean potentially overtreating (i.e., causing unnecessary side effects) to increase treatment intensity purely based on race with the available data.”
According to the paper, prostate cancer incidence in men with higher PSA levels increases with increasing age, even when using age-adjusted thresholds.
Dr. George says we know from this study and other studies as well that Black men are more likely to be diagnosed with prostate at a younger age. “Therefore, we probably need to be thinking about screening Black men starting at a younger age. These are the men who are most likely to benefit from an intervention — patients who have life expectancies of 20 years or more.”
What are the Downsides to Overdiagnosing Prostate Cancer in Men?
“It’s one of the biggest concerns that men have in proactively seeking healthcare,” Dr. George says. “They’re more likely to undergo treatment for this disease if they’re getting screened because (clinicians are) more likely to find it.”
Some of those men, he says, are going to undergo treatment for disease that won’t ultimately kill them, but may cause complications the men shouldn’t have had at all or otherwise may have had later.
“Overtreatment is a real concern. That’s why active surveillance is so important to minimize overtreatment of patients by finding out which cancers are low risk for progression and which are becoming more aggressive,” Dr. George says.
Authors of the study write that “the potential for overdiagnosis and the subsequent psychological and physical impact of diagnosis and treatment is an important consideration.”
All authors of the new paper received financial support from Cancer Research UK, the National Institute for Health and Care Research (NIHR), and the Higgins family for the submitted work.

There was a substantial difference in prostate cancer diagnosis across ethnic groups: 25% of Black men with a raised PSA were diagnosed with prostate cancer within 1 year of being tested, compared with 20% of White men and 13% of Asian men, in the analysis of a large primary care cohort in the United Kingdom.
Incidence of advanced prostate cancer for Asian men with a raised PSA result was 4.5%, compared with 7.5% for White men and 7.0% for Black men.
Men included in the study were aged 40 and older and had no prior cancer diagnosis. Their ethnicity and PSA test result were logged in a national dataset between 2010 and 2017.
The study of more than 730,000 men, published in BMC Medicine, didn’t explore reasons for the differences, but experts offer their thoughts on what led to the findings and what these results imply.
Why the Higher Diagnosis Rates but Not More Advanced Disease in Black Men?
Lead author Liz Down, a graduate research assistant at the University of Exeter, Exeter, England, suggests the higher diagnosis rates but not more advanced disease in Black men may be linked to genetic variations.
Her team’s studies have shown that Black men in the United Kingdom and United States have higher levels of PSA. The PSA value is used to identify patients who might benefit from specialist investigation, and current guidelines in the UK and US don’t distinguish between ethnic groups.
As most men have slow-growing prostate cancer, this may lead to a disproportionately higher number of Black men being diagnosed with prostate cancer, she said.
“One possible interpretation,” Ms. Down notes, “is that prostate cancer follows a similar trajectory in Black and White men. What is different, however, is that Black men have higher PSA levels.”
As to why the advanced-cancer incidence is similar in Black and White patients in the study, Daniel George, MD, director of genitourinary oncology at Duke Cancer Institute in Durham, North Carolina, says it’s important to understand that the Black men in this study “are not necessarily representative of the Black population at large.”
In this study, “they’re a little bit more healthcare inclined,” Dr. George notes. The study population is actively seeking the PSA test. Their socioeconomic profile might be closer to their White counterparts’, and that may make results more similar, he said.
“It’s possible that because this is a screening and not just men coming in for symptoms or cause, that we’re not seeing as much advanced disease,” he continued.
Amar Kishan, MD, chief of the genitourinary oncology service at University of California Los Angeles (UCLA) Health, says the genomic factors and environmental stressors that lead to elevated PSA counts don’t necessarily translate into aggressiveness of disease.
Why do Different Races have Different Prostate Cancer Risk?
Dr. George points out that the study also highlights that Asian men were significantly less likely to be diagnosed with prostate cancer within 1 year of the test.
The reasons for differences in prostate risk by race are complex, he notes. There are some clues that biologic factors may be at work. For instance, early puberty has a link to prostate cancer as it does to breast cancer, and height is also associated with a greater risk of prostate cancer, Dr. George said.
It’s not necessarily a racial association but there are some biological factors associated with prostate cancer later in life, he explained. “These may be enriched in certain populations, including northern Europeans and patients with African ancestries.”
The study also notes that Black men are more likely to die from prostate cancer than are White men, and Asian men are less likely than White or Black men to die from it.
Ms. Down said the difference in prostate cancer mortality between Black vs White men, in particular, may be related to a number of factors, and age, and lifetime risk of prostate cancer may play a major role, at least in the UK.
Should There Be Different ‘Normal’ PSA Levels for Different Races?
Dr. George says there is likely a need to change the system because a PSA level in one race may not signal the same risk it does in another. So medicine probably needs to standardize what a “normal” PSA is by race, he says, adding that he is a coauthor of an upcoming paper regarding that issue.

Dupilumab for Eosinophilic Esophagitis: How Is it Improving Treatment?
The US Food and Drug Administration approvals of dupilumab (Dupixent, Regeneron/Sanofi) for adults and children with eosinophilic esophagitis (EoE) affirmed the safety and efficacy of the drug, which is the first product indicated specifically for treatment of this disease.
The recent expanded approval for its use in kids aged 1 year and older imply that clinicians can prescribe it for just about any patient with the immune disorder.
But is dupilumab right for everyone?
What the Trials Said
Dupilumab, given by injection, is a recombinant human immunoglobulin-G4 monoclonal antibody that inhibits interleukin 4 (IL-4) and IL-13 signaling.
The first approval for EoE, on May 22, 2022, for adults and children aged 12 years and older weighing at least 40 kg, was based on data from 321 participants in the first two parts of a three-part phase 3 trial involving patients with EoE despite 8 weeks of high-dose proton pump inhibitor (PPI) therapy and with substantial symptom burden.
At 24 weeks, histologic remission occurred in 60% of patients in Part A of the trial and 59% in Part B who received a weekly 300-mg dose of dupilumab compared with 5% and 6% taking placebo. Additionally, Part A and B participants taking the drug weekly experienced a 69% and 64% reduction in disease symptoms, respectively, vs 32% and 41% for placebo. The drug also outperformed placebo in reducing patients’ esophageal eosinophilic counts and abnormal endoscopic findings.
The second approval, on January 25, 2024, for children aged 1 year and older weighing at least 15 kg, was based on data from a two-part, placebo-controlled trial involving 102 children, ages 1-11 years, with EoE. The study involved a 16-week treatment period and a 36-week extended period during which eligible children from the dupilumab group continued to receive their weight-based dose level and those who were on placebo switched to active treatment. The trial showed that a greater proportion of children taking the drug achieved histological remission.
A Major Advance but Temper Expectations
,” Philip Katz, MD, AGAF, professor of medicine in the gastroenterology division at Weill Cornell Medicine, New York City, said in an interview. “I’ve been using it since The New England Journal of Medicine paper was published about a year and a half ago , and as a slow adopter, I like it.”
Dr. Katz and his colleagues have been prescribing dupilumab mainly for patients who haven’t responded to other medications, mainly PPIs and steroids.
“We start people on it without stopping anything else,” Dr. Katz said. “Then, as symptoms evolve and people have a positive response, we stop the other medications. For example, in one patient who did very well on the drug, we stopped his steroids and now, we’re weaning him off his PPI. It’s a process. This is not a disease where you can rush people.”
The tempered approach is in part because of payer issues, he noted.
“It’s very difficult to get it reimbursed in the US if you haven’t tried something else first,” Dr. Katz said. “And because it’s still relatively new in this field, standard treatment is still used frequently.”
Although Dr. Katz has had “incredible success” with dupilumab so far, “nothing should be considered a miracle drug,” he said. “A couple of people have had injection reactions, and one person couldn’t tolerate the drug. So, while it seems to have an excellent response rate, it’s not 100%. Like any new drug, it will have to find its true success rate.”
Taking a Step-Up Approach
Like Dr. Katz, Evan Dellon, MD, MPH, AGAF, director of the Center for Esophageal Diseases and Swallowing at the University of North Carolina at Chapel Hill, North Carolina, is enthusiastic about dupilumab.
“It’s a boon to the field, and now, some real-world data are coming out and looking very much like the clinical trial data, which are reassuring,” said Dr. Dellon, a coauthor of The New England Journal of Medicine paper.
It’s been a “game changer,” particularly for people who weren’t doing well with their current treatments, he said. “In my practice, I’ve been seeing a lowish response rate for PPIs, and about 30%-40% not responding to topical steroids, since we don’t have a standard formulation for that. The diet elimination therapy is effective if people can do it well and adhere to it. But there’s a group of people who don’t respond, and probably, a larger group who can’t really do that treatment long term. So, the drug has been fantastic for those patients.”
Although the drug is approved for patients aged 1 year and older with no caveats, “it’s not the right medicine for every patient,” he said. “Patients in the clinical trials had EoE for 5 years, many of them were treatment refractory, and just under half had dilations and strictures,” he said. “They represent a certain group of patients.”
Dr. Dellon is taking a “step-up approach” to EoE treatment, first trying the standard interventions — PPIs, steroids, and an elimination diet — that many patients do respond to.
For new patients who choose medication therapy, he prescribes PPIs and then topical steroids and then steps up to dupilumab for patients who aren’t responding or who have a strong preference for starting the drug early.
In addition to EoE, the drug is approved for certain patients with atopic dermatitis, asthma, and chronic rhinosinusitis with nasal polyposis. As such, Dr. Dellon said that he will try dupilumab early on in patients with multiple atopic conditions, such as asthma, eczema, or nasal disease.
“Even if their EoE is not that severe, those patients can still benefit from a more streamlined systemic therapy,” he said.
Challenges and Questions Still Remain
Not surprisingly, both Dr. Katz and Dr. Dellon pointed to dupilumab’s cost and the related challenge of convincing insurance companies to cover the drug as major challenges to more widespread use. The lack of long-term data also poses a challenge.
Side effects, which often stand in the way of the use of a new drug, are not an issue, for the most part, at least in the short term, according to Dr. Dellon. The most common side effects are discomfort, redness at the injection site, and pain related to the injection.
“Keeping the medication out of the refrigerator for a bit to bring it up to room temperature can help, as can doing the injection in the lower abdomen,” he said. “Otherwise, it’s well tolerated, with no side effects that are unique to EoE.”
Data from the third part of the clinical trial, which followed patients from weeks 24-52 of treatment, indicated that improvements in histological, symptomatic, endoscopic, and molecular features of EoE among patients taking weekly dupilumab continued or improved.
In my practice, “my observations have been that people are maintaining their responses,” said Dr. Dellon, a coauthor of the paper on the study’s third part.
However, one critical question is whether the dose intensity and/or frequency can be decreased over time without reducing the response rate.
“Hopefully, we’ll start getting data on that in the next year or two,” Dr. Dellon said. “It’s hard to do that yet because the drug has only been out for a year or year and a half, and people are just getting to that year of the initial dosing.”
Another question is how to use the drug in people who are different from the clinical trial population, such as those who have been responding to other therapies but want to switch, and people who are newly diagnosed but who have severe disease. Can the drug be used earlier in these populations?
Dr. Dellon would like to see a study that utilizes the new EoE index of severity metric to focus specifically on dupilumab use in patients with severe disease.
Early findings from his recent real-world study of 46 patients with severe disease who would not have qualified for the clinical trials found histologic, endoscopic, and symptom improvement in 91% of patients with refractory and fibrostenotic EoE after 6 months of dupilumab treatment.
While women tend to be well represented in the clinical trial, the drug needs to be tested in a more diverse population, Dr. Dellon noted. Research is underway looking at dupilumab effectiveness in people with different race/ethnicities.
EoE is more common among White people but that may be the result of a “detection issue,” he said. “When clinicians see a Black or Hispanic patient with dysphagia, for example, they may not be thinking of EoE. And there are also some data suggesting that EoE presents slightly differently in non-White populations, which again could decrease the suspicion for it. This is an area we need to learn more about.”
Don’t ‘Abandon’ Current Interventions
“We’ve got an exciting drug that is going to help a lot of people with a complex disease,” Dr. Katz said. “But we should not forget that there are other interventions that have been successful, and quite frankly, they don’t need to be abandoned.”
“Learn about the drug if you’ve never used it,” he advised. “Read the studies so you understand who the patients were as a baseline for where you’re going to use it. Be prepared to do the appropriate paperwork requirements to get approvals from insurers. And look for more literature because it’s coming.”
“Overall, dupilumab has really changed care in people with moderate to severe disease who are not responding or are intolerant to the other treatments,” Dr. Dellon said. “That’s the natural place for the medication to go at this point.”

So, while it seems to have an excellent response rate, it’s not 100%. Like any new drug, it will have to find its true success rate.”
Taking a Step-Up Approach
Like Dr. Katz, Evan Dellon, MD, MPH, AGAF, director of the Center for Esophageal Diseases and Swallowing at the University of North Carolina at Chapel Hill, North Carolina, is enthusiastic about dupilumab.
“It’s a boon to the field, and now, some real-world data are coming out and looking very much like the clinical trial data, which are reassuring,” said Dr. Dellon, a coauthor of The New England Journal of Medicine paper.
It’s been a “game changer,” particularly for people who weren’t doing well with their current treatments, he said. “In my practice, I’ve been seeing a lowish response rate for PPIs, and about 30%-40% not responding to topical steroids, since we don’t have a standard formulation for that. The diet elimination therapy is effective if people can do it well and adhere to it. But there’s a group of people who don’t respond, and probably, a larger group who can’t really do that treatment long term. So, the drug has been fantastic for those patients.”
Although the drug is approved for patients aged 1 year and older with no caveats, “it’s not the right medicine for every patient,” he said. “Patients in the clinical trials had EoE for 5 years, many of them were treatment refractory, and just under half had dilations and strictures,” he said. “They represent a certain group of patients.”
Dr. Dellon is taking a “step-up approach” to EoE treatment, first trying the standard interventions — PPIs, steroids, and an elimination diet — that many patients do respond to.
For new patients who choose medication therapy, he prescribes PPIs and then topical steroids and then steps up to dupilumab for patients who aren’t responding or who have a strong preference for starting the drug early.
In addition to EoE, the drug is approved for certain patients with atopic dermatitis, asthma, and chronic rhinosinusitis with nasal polyposis. As such, Dr. Dellon said that he will try dupilumab early on in patients with multiple atopic conditions, such as asthma, eczema, or nasal disease.
“Even if their EoE is not that severe, those patients can still benefit from a more streamlined systemic therapy,” he said.
Challenges and Questions Still Remain
Not surprisingly, both Dr. Katz and Dr. Dellon pointed to dupilumab’s cost and the related challenge of convincing insurance companies to cover the drug as major challenges to more widespread use. The lack of long-term data also poses a challenge.
Side effects, which often stand in the way of the use of a new drug, are not an issue, for the most part, at least in the short term, according to Dr. Dellon. The most common side effects are discomfort, redness at the injection site, and pain related to the injection.
“Keeping the medication out of the refrigerator for a bit to bring it up to room temperature can help, as can doing the injection in the lower abdomen,” he said. “Otherwise, it’s well tolerated, with no side effects that are unique to EoE.”
Data from the third part of the clinical trial, which followed patients from weeks 24-52 of treatment, indicated that improvements in histological, symptomatic, endoscopic, and molecular features of EoE among patients taking weekly dupilumab continued or improved.
In my practice, “my observations have been that people are maintaining their responses,” said Dr. Dellon, a coauthor of the paper on the study’s third part.
However, one critical question is whether the dose intensity and/or frequency can be decreased over time without reducing the response rate.
“Hopefully, we’ll start getting data on that in the next year or two,” Dr. Dellon said. “It’s hard to do that yet because the drug has only been out for a year or year and a half, and people are just getting to that year of the initial dosing.”
Another question is how to use the drug in people who are different from the clinical trial population, such as those who have been responding to other therapies but want to switch, and people who are newly diagnosed but who have severe disease. Can the drug be used earlier in these populations?
Dr. Dellon would like to see a study that utilizes the new EoE index of severity metric to focus specifically on dupilumab use in patients with severe disease.
Early findings from his recent real-world study of 46 patients with severe disease who would not have qualified for the clinical trials found histologic, endoscopic, and symptom improvement in 91% of patients with refractory and fibrostenotic EoE after 6 months of dupilumab treatment.
While women tend to be well represented in the clinical trial, the drug needs to be tested in a more diverse population, Dr. Dellon noted. Research is underway looking at dupilumab effectiveness in people with different race/ethnicities.
EoE is more common among White people but that may be the result of a “detection issue,” he said. “When clinicians see a Black or Hispanic patient with dysphagia, for example, they may not be thinking of EoE. And there are also some data suggesting that EoE presents slightly differently in non-White populations, which again could decrease the suspicion for it. This is an area we need to learn more about.”
Don’t ‘Abandon’ Current Interventions
“We’ve got an exciting drug that is going to help a lot of people with a complex disease,” Dr. Katz said. “But we should not forget that there are other interventions that have been successful, and quite frankly, they don’t need to be abandoned.”
“Learn about the drug if you’ve never used it,” he advised. “Read the studies so you understand who the patients were as a baseline for where you’re going to use it. Be prepared to do the appropriate paperwork requirements to get approvals from insurers. And look for more literature because it’s coming.”
“Overall, dupilumab has really changed care in people with moderate to severe disease who are not responding or are intolerant to the other treatments,” Dr. Dellon said. “That’s the natural place for the medication to go at this point.”
Dr. Katz is a consultant to Phathom Pharma, Sebela Pharma, Medpace (not active), and Medtronic.
Dr. Dellon received research funding from Adare/Ellodi, Allakos, Arena/Pfizer, AstraZeneca, Eupraxia, Ferring, GSK, Meritage, Miraca, Nutricia, Celgene/Receptos/BMS, Regeneron, Revolo, and Shire/Takeda.

New Cancer Surgical Tech Gets Positive Vote, But Some Cite Safety Concerns
A majority of the US Food and Drug Administration’s Medical Imaging Drugs Advisory Committee (MIDAC) on March 5 voted in support of LUMISIGHT’s (pegulicianine) benefit-risk profile.
LUMISIGHT is an optical imaging agent used in combination with Lumicell Direct Visualization System (DVS), a fluorescence-guided imaging system. The technology, developed by Lumicell Inc., helps surgeons identify cancer that may remain in the breast after they’ve completed the main resection of tissue.
Following MIDAC’s positive vote, the FDA will move on to reviewing Lumicell’s new drug application for LUMISIGHT and its premarket approval application for Lumicell DVS.
“We are proud of the efforts and look forward to the next steps as we work with the FDA to finalize the approval process so that women with breast cancer can access the therapy,” Jorge Ferrer, PhD, Lumicell’s chief scientific officer, said in an interview.
However, Freya Schnabel, MD, professor of surgery and director of breast surgery at NYU Perlmutter Cancer Center, said there are some “real concerns” with the technology. She expressed surprise at MIDAC’s overall favorable vote.
In a recently published study, she noted that the use of pegulicianine fluorescence-guided surgery (pFGS) did not meet the prespecified threshold for sensitivity.
“It did meet thresholds for removal of residual tumor and specificity — but this is still basically a negative study, and a low sensitivity raises concerns regarding false negative readings,” she said in an interview. “I’m surprised [the committee] is supportive in light of this result. Also, the technique is logistically challenging, as patients need to be injected 2 to 6 hours before their surgeries, very challenging timing for patients having ambulatory procedures.”
The study, published in the April 2023 NEJM Evidence, analyzed 357 patients who received 1.0 mg/kg intravenous pegulicianine followed by lumpectomy. Tumor left behind after standard lumpectomy was removed in 27 of 357 patients through use of pFGS. Of the 27, 22 patients had cavity orientations deemed “negative” on standard margin evaluation, according to the study. A margin is described as negative or clean when there are no further cancer cells at the edge of the tissue, suggesting that all of the cancer has been removed. Second surgeries were avoided by pFGS in 9 of 62 patients with positive margins, the analysis found.
On per-margin analysis, pFGS specificity was 85.2%, and sensitivity was 49.3%. While the sensitivity endpoint missed the lower boundary of the 95% confidence interval, the LUM system exceeded the specificity endpoint of 60% with a point estimate of 86%, and an accuracy of 84% for imaging residual cancer in the lumpectomy cavity, coinvestigator E. Shelley Hwang, MD, MPH, said during the MIDAC meeting.
“The pivotal study was an adequate and well-controlled study demonstrating the effectiveness of the LUM system to detect residual cancer in the lumpectomy cavity, following the standard of care procedure,” she said. “These results also demonstrate clinical benefit that improves the current standard of care. This is the first and only imaging system that provides results in the lumpectomy cavity in real time, allowing surgeons to use this information at the time of the initial procedure.”
Is the Technology Safe?
Pegulicianine is an imaging agent that contains a fluorescent dye. The agent is given to patients as a 3-minute intravenous infusion 2 to 6 hours before surgery.
After removal of the main tumor specimen, the surgeon inserts a handheld probe into the breast cavity and in combination with the detection software, searches for residual cancer that may have been left behind, Dr. Ferrer explained during the MIDAC meeting.
If the software identifies areas suspicious for residual cancer, those areas display in red on an overhead screen. The surgeon then takes a targeted shave to resect the suspicious tissue. Once the tissue has been removed, the surgeon can rescan the cavity with the probe to ensure a more complete resection has been performed. Use of the LUM system typically takes surgeons less than 7 minutes to use, Dr. Ferrer said.
In the study, a total of 406 patients received the intravenous pegulicianine, but 14 patients were withdrawn before randomization. After a standard lumpectomy procedure, 357 patients were assigned to the pFGS group and 35 patients to the control group.
Of the 406 patients, pegulicianine administration was stopped for adverse events in 6 patients (1.5%). Two patients had grade 3 serious adverse events related to pegulicianine; one had hypersensitivity, and one had an anaphylactic reaction. The other four pegulicianine-related adverse events included allergic reaction, milder hypersensitivity, nausea, and pegulicianine extravasation.
Dr. Schnabel said these reactions are worrisome. While any effort to reduce the need for patients to have more than one surgery to complete a breast conserving approach would be a “real advance,” Dr. Schnabel said she would not feel comfortable using pFGS in her own practice if approved by the FDA as is.
“This is clearly a major issue in terms of incorporating this technique into practice,” she said. “I could go on, but in light of the above, I’m surprised that [the committee] is supportive. I would hope for some refinement of the technique to reduce the risks to patients and improve the results before I’d consider utilizing this approach.”
During the MIDAC meeting, Dr. Ferrer said the company takes the safety events seriously and has developed mitigation strategies to further reduce the risk of patient hypersensitivity. These strategies include: clear labeling that informs users of anaphylaxis risk, incorporating a new section into the device training program to address warnings and precautions, an enhanced pharmacovigilance program to closely track and report hypersensitivity events, and a postmarket study to access the incidence rate and risk of such events in a broader population.
Several MIDAC members raised questions about the adverse reactions observed and about the safety of the technology.
David B. Hackney, MD, a neuroradiologist at Beth Israel Deaconess Medical Center in Boston, questioned the recommendation that patients only be monitored for 15 minutes after the injection.
“Since you don’t have enough data to know how long after injection reactions could occur, why not keep them under monitoring until after the surgery is over?” he said.
Barbara Smith, MD, PhD, lead investigator of the study, explained that per the protocol, there would be frequent monitoring, with a nurse at bedside, and patients would be monitored after injection, on their way to the procedure, and afterward.
She suggested, during the meeting, that more intense monitoring early in the process would be beneficial as that is when investigators observed side effects believed to be attributed to LUMISIGHT.
MIDAC member Kimberly E. Applegate, MD, a retired radiology professor, asked about the learning curve for surgeons and how long it generally takes for physicians to become familiar with the system.
Coinvestigator Kelly Hunt, MD, explained that all surgeons who participated in the trial completed a training program.
“Certainly, there’s a learning curve anytime we introduce new technology in the operating room,” she said. “Surgeons said it usually takes about three procedures before they’re comfortable with the system, including the camera and the software.”
During a presentation period by FDA officials, Anil Rajpal, MD, MPH, FDA, Deputy Division Director for Safety, said it’s important that prescribing information for LUMISIGHT communicate the risk of anaphylaxis and other hypersensitivity reactions, the need to monitor patients, and the need for the appropriate available personnel, medications, and equipment.
“This would be done by warnings and precautions and a boxed warning,” he said. “Note, that [such warnings] would only communicate the risks, it would not further characterize the risk.”
Committee Expresses Support
During a subsequent vote among committee members, most expressed support for the technology and its benefits. Sixteen members voted in support, one abstained, and two voted against the benefit-risk profile.
Andrea Richardson, MD, PhD, professor of pathology at Johns Hopkins in Baltimore, said she voted yes because the incremental benefits of avoiding additional surgeries outweigh the small risk of anaphylaxis.
Henry Royal, MD, MIDAC chair and professor of radiology at Washington University School of Medicine in St. Louis, agreed.
“Even though the benefit of this is on average, quite small, the benefit to the woman who has positive margins that’s converted to negative margins because of use of [LUMISIGHT] is really quite great,” he said. “The risk from this procedure is certainly very manageable.”
Harold J. Burstein, MD, PhD, a professor of medicine at Harvard Medical School and oncologist at Dana-Farber Cancer Institute in Boston, voted against the benefit-risk profile. He said the technology merits more research and that he does not believe it was proven the technology reduces the risk of reoperation.
“I think it’s a great technology,” he said. “I would like to see a well-conducted, randomized, phase III study with the endpoint of reoperation,” he said. “That would really prove the usefulness and benefit of the intervention in my mind.”
Chengjie Xiong, PhD, professor of biostatistics at Washington University School of Medicine in St. Louis, chose to abstain from voting because he said there was not enough data.
The FDA will now complete its review of Lumicell’s new drug application for LUMISIGHT and review of its premarket approval application for Lumicell DVS. The FDA review team has 6-10 months to make a decision. As part of the process, the FDA will evaluate clinical data, travel to clinical study sites to conduct inspections, and assemble a final action package for a senior FDA official to make a final decision.
If deemed safe and effective, the FDA will then work with Lumicell on developing and refining prescribing information.
Dr. Ferrer said his team expects to receive FDA approval in the coming weeks and will continue to work collaboratively with the FDA to expedite approval where possible.
The purpose of the MIDAC is to review and evaluate data about the safety and effectiveness of marketed and investigational human drug products for use in diagnostic and therapeutic procedures using radioactive pharmaceuticals and make appropriate recommendations to the FDA Commissioner.

Andrea Richardson, MD, PhD, professor of pathology at Johns Hopkins in Baltimore, said she voted yes because the incremental benefits of avoiding additional surgeries outweigh the small risk of anaphylaxis.
Henry Royal, MD, MIDAC chair and professor of radiology at Washington University School of Medicine in St. Louis, agreed.
“Even though the benefit of this is on average, quite small, the benefit to the woman who has positive margins that’s converted to negative margins because of use of [LUMISIGHT] is really quite great,” he said. “The risk from this procedure is certainly very manageable.”
Harold J. Burstein, MD, PhD, a professor of medicine at Harvard Medical School and oncologist at Dana-Farber Cancer Institute in Boston, voted against the benefit-risk profile. He said the technology merits more research and that he does not believe it was proven the technology reduces the risk of reoperation.
“I think it’s a great technology,” he said. “I would like to see a well-conducted, randomized, phase III study with the endpoint of reoperation,” he said. “That would really prove the usefulness and benefit of the intervention in my mind.”
Chengjie Xiong, PhD, professor of biostatistics at Washington University School of Medicine in St. Louis, chose to abstain from voting because he said there was not enough data.
The FDA will now complete its review of Lumicell’s new drug application for LUMISIGHT and review of its premarket approval application for Lumicell DVS. The FDA review team has 6-10 months to make a decision. As part of the process, the FDA will evaluate clinical data, travel to clinical study sites to conduct inspections, and assemble a final action package for a senior FDA official to make a final decision.
If deemed safe and effective, the FDA will then work with Lumicell on developing and refining prescribing information.
Dr. Ferrer said his team expects to receive FDA approval in the coming weeks and will continue to work collaboratively with the FDA to expedite approval where possible.
The purpose of the MIDAC is to review and evaluate data about the safety and effectiveness of marketed and investigational human drug products for use in diagnostic and therapeutic procedures using radioactive pharmaceuticals and make appropriate recommendations to the FDA Commissioner.
Does Exercise Reduce Cancer Risk? It’s Just Not That Simple
“Exercise is medicine” has become something of a mantra, with good reason. There’s no doubt that regular physical activity has a broad range of health benefits. Exercise can improve circulation, help control weight, reduce stress, and boost mood — take your pick.
Lower cancer risk is also on the list — with exercise promoted as a risk-cutting strategy in government guidelines and in recommendations from professional groups such as the American Cancer Society.
The bulk of the data hangs on less rigorous, observational studies that have linked physical activity to lower risks for certain cancers, but plenty of questions remain.
What are the cancer types where exercise makes a difference? How significant is that impact? And what, exactly, defines a physical activity pattern powerful enough to move the needle on cancer risk?
Here’s an overview of the state of the evidence.
Exercise and Cancer Types: A Mixed Bag
When it comes to cancer prevention strategies, guidelines uniformly endorse less couch time and more movement. But a deeper look at the science reveals a complex and often poorly understood connection between exercise and cancer risk.
For certain cancer types, the benefits of exercise on cancer risk seem fairly well established.
The latest edition of the Physical Activity Guidelines for Americans, published in 2018, cites “strong evidence” that regular exercise might curb the risks for breast and colon cancers as well as bladder, endometrial, esophageal, kidney, and gastric cancers. These guidelines also point to “moderate”-strength evidence of a protective association with lung cancer.
The evidence of a protective effect, however, is strongest for breast and colon cancers, said Jennifer Ligibel, MD, senior physician in the Breast Oncology Center at Dana-Farber Cancer Institute, Boston, . “But,” she pointed out, “that may be because they’re some of the most common cancers, and it’s been easier to detect an association.”
Guidelines from the American Cancer Society, published in 2020, align with the 2018 recommendations.
“We believe there’s strong evidence to suggest at least eight different types of cancer are associated with physical activity,” said Erika Rees-Punia, PhD, MPH, senior principal scientist, epidemiology and behavioral research at the American Cancer Society.
That view is not universal, however. Current recommendations from the World Cancer Research Fund and American Institute for Cancer Research, for example, are more circumspect, citing only three cancers with good evidence of a protective effect from exercise: Breast (postmenopausal), colon, and endometrial.
“We definitely can’t say exercise reduces the risk of all cancers,” said Lee Jones, PhD, head of the Exercise Oncology Program at Memorial Sloan Kettering Cancer Center in New York City. “The data suggest it’s just not that simple.”
And it’s challenging to put all the evidence together, Dr. Jones added.
The physical activity guidelines are based on published systematic reviews, meta-analyses, and pooled analyses of data from observational studies that examined the relationship between physical activity — aerobic exercise, specifically — and cancer incidence. That means the evidence comes with all the limitations observational studies entail, such as how they collect information on participants’ exercise habits — which, Dr. Jones noted, is typically done via “monster questionnaires” that gauge physical activity in broad strokes.
Pooling all those findings into a meta-analysis is tricky, Dr. Jones added, because individual studies vary in important ways — from follow-up periods to how they quantify exercise and track cancer incidence.
In a study published in February in Cancer Cell, Dr. Jones and his colleagues attempted to address some of those issues by leveraging data from the PLCO screening trial.
The PLCO was a prospective study of over 60,000 US adults that compared the effects of annual screening vs usual care on cancer mortality. At enrollment, participants completed questionnaires that included an assessment of “vigorous” exercise. Based on that, Dr. Jones and his colleagues classified 55% as “exercisers” — meaning they reported 2 or more hours of vigorous exercise per week. The remaining 45%, who were in the 0 to 1 hour per week range, were deemed non-exercisers.
Over a median of 18 years, nearly 16,000 first-time invasive cancers were diagnosed, and some interesting differences between exercisers and non-exercisers emerged. The active group had lower risks for three cancers: Head and neck, with a 26% lower risk (hazard ratio [HR], 0.74), lung (a 20% lower risk), and breast (an 11% lower risk).
What was striking, however, was the lack of connection between exercise and many cancers cited in the guidelines, including colon, gastric, bladder, endometrial, and renal cancers.
Perhaps even more surprising — exercisers had higher risks for prostate cancer (12%) and melanoma (20%). This finding, Dr. Jones said, is in line with a previous pooled analysis of data from 12 US and European prospective cohorts. In this study, the most physically active participants (90th percentile) had higher risks for melanoma and prostate cancer, compared with the least active group (10th percentile).
The melanoma findings do make sense, Dr. Jones said, given that highly active people may spend a lot of time in the sun. “My advice,” Dr. Jones said, “is, if you’re exercising outside, wear sunscreen.” The prostate cancer findings, however, are more puzzling and warrant further research, he noted.
But the bottom line is that the relationship between exercise and cancer types is mixed and far from nailed down.
How Big Is the Effect?
Even if exercise reduces the risk for only certain cancers, that’s still important, particularly when those links appear strongest for common cancer types, such as breast and colon.
But how much of a difference can exercise make?
Based on the evidence, it may only be a modest one. A 2019 systematic review by the Physical Activity Guidelines Advisory Committee provided a rough estimate: Across hundreds of epidemiological studies, people with the highest physical activity levels had a 10%-20% lower risk for the cancers cited in the 2018 exercise guidelines compared with people who were least active.
These figures, however, are probably an underestimate, said Anne McTiernan, MD, PhD, a member of the advisory committee and professor of epidemiology, at Fred Hutchinson Cancer Center, Seattle.
“This is what we usually see when a factor is not measured very well,” said Dr. McTiernan, explaining that the individual studies differed in their categories of “highest” and “lowest” physical activity, such that one study’s “highest” could be another’s mid-range.
“In other words, the effects of physical activity are likely larger” than the review found, Dr. McTiernan said.
The next logical question is whether a bigger exercise “dose” — more time or higher intensity — would have a greater impact on cancer risk. A 2019 study published in the Journal of Clinical Oncology tried to clarify that by pooling data on over 750,000 participants from nine prospective cohorts.
Overall, people meeting government recommendations for exercise — equivalent to about 2.5-5 hours of weekly moderate activity, such as a brisk walk, or about 1.25-2.5 hours of more vigorous activities, like running — had lower risks for seven of 15 cancer types studied compared with less active people.
For cancers with positive findings, being on the higher end of the recommended 2.5- to 5-hour weekly range was better. Risk reductions for breast cancer, for instance, were 6% at 2.5 hours of physical activity per week and 10% at 5 hours per week. Similar trends emerged for other cancer types, including colon (8%-14%), endometrial (10%-18%), liver cancer (18%-27%), and non-Hodgkin lymphoma in women (11%-18%).
But there may be an exercise sweet spot that maximizes the cancer risk benefit.
Among people who surpassed the recommendations — exercising for more time or more intensely — the risk reduction benefit did not necessarily improve in a linear fashion. For certain cancer types, such as colon and endometrial, the benefits of more vigorous exercise “eroded at higher levels of activity,” the authors said.
The issue here is that most studies have not dug deeply into aerobic exercise habits. Often, studies present participants with a list of activities — walking, biking, and running — and ask them to estimate how often and for what duration they do each.
Plus, “we’ve usually lumped moderate and vigorous activities together,” Dr. Rees-Punia said, which means there’s a lack of “granular data” to say whether certain intensities or frequencies of exercise are optimal and for whom.
Why Exercise May Lower Cancer Risk
Exercise habits do not, of course, exist in a vacuum. Highly active people, Dr. Ligibel said, tend to be of higher socioeconomic status, leaner, and have generally healthier lifestyles than sedentary people.
Body weight is a big confounder as well. However, Dr. Rees-Punia noted, it’s also probably a reason that exercise is linked to lower cancer risks, particularly by preventing weight gain. Still, studies have found that the association between exercise and many cancers remains significant after adjusting for body mass index.
The why remains unclear, though some studies offer clues.
“There’s been some really interesting mechanistic research, suggesting that exercise may help inhibit tumor growth or upregulate the immune system,” Dr. Ligibel said.
That includes not only lab research but small intervention studies. While these studies have largely involved people who already have cancer, some have also focused on healthy individuals.
A 2019 study from Dr. Ligibel and her colleagues, which randomly assigned 49 women newly diagnosed with breast cancer to start either an exercise program or mind-body practices ahead of surgery, found exercisers, who had been active for about a month at the time of surgery, showed signs of immune system upregulation in their tumors, while the control group did not.
Among healthy postmenopausal women, a meta-analysis of six clinical trials from Dr. McTiernan and her colleagues found that exercise plus calorie reduction can reduce levels of breast cancer-related endogenous hormones, more so than calorie-cutting alone. And a 2023 study found that high-intensity exercise boosted the ranks of certain immune cells and reduced inflammation in the colon among people at high risk for colon and endometrial cancers due to Lynch syndrome.
Defining an Exercise ‘Prescription’
Despite the gaps and uncertainties in the research, government guidelines as well as those from the American Cancer Society and other medical groups are in lockstep in their exercise recommendations: Adults should strive for 150-300 minutes of moderate-intensity aerobic exercise (like brisk walking), 75-150 minutes of vigorous activity (like running), or some combination each week.
The guidelines also encourage strength training twice a week — advice that’s based on research tying those activity levels to lower risks for heart disease, diabetes, and other chronic conditions.
But there’s no “best” exercise prescription for lowering cancer risk specifically. Most epidemiological studies have examined only aerobic activity, Dr. Rees-Punia said, and there’s very little known about whether strength conditioning or other moderate heart rate-elevating activities, such as daily household chores, may reduce the risk for cancer.
Given the lack of nuance in the literature, it’s hard to say what intensities, types, or amounts of exercise are best for each individual.
Going forward, device-based measurements of physical activity could “help us sort out the effects of different intensities of exercise and possibly types,” Dr. Rees-Punia said.
But overall, Dr. McTiernan said, the data do show that the risks for several cancers are lower at the widely recommended activity levels.
“The bottom-line advice is still to exercise at least 150 minutes per week at a moderate-intensity level or greater,” Dr. McTiernan said.
Or put another way, moving beats being sedentary. It’s probably wise for everyone to sit less, noted Dr. Rees-Punia, for overall health and based on evidence tying sedentary time to the risks for certain cancers, including colon, endometrial, and lung.
There’s a practical element to consider in all of this: What physical activities will people actually do on the regular? In the big epidemiological studies, Dr. McTiernan noted, middle-aged and older adults most often report walking, suggesting that’s the preferred, or most accessible activity, for many.
“You can only benefit from the physical activity you’ll actually do,” Dr. Rees-Punia said.
Dr. Ligibel echoed that sentiment, saying she encourages patients to think about physical activity as a process: “You need to find things you like to do and work them into your daily life, in a sustainable way.
“People often talk about exercise being medicine,” Dr. Ligibel said. “But I think you could take that too far. If we get too prescriptive about it, that could take the joy away.”

The issue here is that most studies have not dug deeply into aerobic exercise habits. Often, studies present participants with a list of activities — walking, biking, and running — and ask them to estimate how often and for what duration they do each.
Plus, “we’ve usually lumped moderate and vigorous activities together,” Dr. Rees-Punia said, which means there’s a lack of “granular data” to say whether certain intensities or frequencies of exercise are optimal and for whom.
Why Exercise May Lower Cancer Risk
Exercise habits do not, of course, exist in a vacuum. Highly active people, Dr. Ligibel said, tend to be of higher socioeconomic status, leaner, and have generally healthier lifestyles than sedentary people.
Body weight is a big confounder as well. However, Dr. Rees-Punia noted, it’s also probably a reason that exercise is linked to lower cancer risks, particularly by preventing weight gain. Still, studies have found that the association between exercise and many cancers remains significant after adjusting for body mass index.
The why remains unclear, though some studies offer clues.
“There’s been some really interesting mechanistic research, suggesting that exercise may help inhibit tumor growth or upregulate the immune system,” Dr. Ligibel said.
That includes not only lab research but small intervention studies. While these studies have largely involved people who already have cancer, some have also focused on healthy individuals.
A 2019 study from Dr. Ligibel and her colleagues, which randomly assigned 49 women newly diagnosed with breast cancer to start either an exercise program or mind-body practices ahead of surgery, found exercisers, who had been active for about a month at the time of surgery, showed signs of immune system upregulation in their tumors, while the control group did not.
Among healthy postmenopausal women, a meta-analysis of six clinical trials from Dr. McTiernan and her colleagues found that exercise plus calorie reduction can reduce levels of breast cancer-related endogenous hormones, more so than calorie-cutting alone. And a 2023 study found that high-intensity exercise boosted the ranks of certain immune cells and reduced inflammation in the colon among people at high risk for colon and endometrial cancers due to Lynch syndrome.
Defining an Exercise ‘Prescription’
Despite the gaps and uncertainties in the research, government guidelines as well as those from the American Cancer Society and other medical groups are in lockstep in their exercise recommendations: Adults should strive for 150-300 minutes of moderate-intensity aerobic exercise (like brisk walking), 75-150 minutes of vigorous activity (like running), or some combination each week.
The guidelines also encourage strength training twice a week — advice that’s based on research tying those activity levels to lower risks for heart disease, diabetes, and other chronic conditions.
But there’s no “best” exercise prescription for lowering cancer risk specifically. Most epidemiological studies have examined only aerobic activity, Dr. Rees-Punia said, and there’s very little known about whether strength conditioning or other moderate heart rate-elevating activities, such as daily household chores, may reduce the risk for cancer.
Given the lack of nuance in the literature, it’s hard to say what intensities, types, or amounts of exercise are best for each individual.
Going forward, device-based measurements of physical activity could “help us sort out the effects of different intensities of exercise and possibly types,” Dr. Rees-Punia said.
But overall, Dr. McTiernan said, the data do show that the risks for several cancers are lower at the widely recommended activity levels.
“The bottom-line advice is still to exercise at least 150 minutes per week at a moderate-intensity level or greater,” Dr. McTiernan said.
Or put another way, moving beats being sedentary. It’s probably wise for everyone to sit less, noted Dr. Rees-Punia, for overall health and based on evidence tying sedentary time to the risks for certain cancers, including colon, endometrial, and lung.
There’s a practical element to consider in all of this: What physical activities will people actually do on the regular? In the big epidemiological studies, Dr. McTiernan noted, middle-aged and older adults most often report walking, suggesting that’s the preferred, or most accessible activity, for many.
“You can only benefit from the physical activity you’ll actually do,” Dr. Rees-Punia said.
Dr. Ligibel echoed that sentiment, saying she encourages patients to think about physical activity as a process: “You need to find things you like to do and work them into your daily life, in a sustainable way.
“People often talk about exercise being medicine,” Dr. Ligibel said. “But I think you could take that too far. If we get too prescriptive about it, that could take the joy away.”

TIL for Melanoma: What Are the Costs and Other Challenges to Getting It to Patients?
The US Food and Drug Administration (FDA) recently approved the tumor-infiltrating lymphocyte cell therapy (TIL) for use in certain adults with unresectable or metastatic melanoma. This marks the first time the FDA has allowed a cellular therapy to be marketed for a solid tumor cancer.
Lifileucel is made from a patient’s surgically removed tumor. Tissue from that tumor is then sent to a manufacturing center. Turnaround time to when the drug is ready to be sent back to the cancer center for use is approximately 34 days, according to the drug’s manufacturer, Iovance.
Insurance Adjustments
The cost of the one-time lifileucel treatment is $515,000, according to the manufacturer.
Two investigators in the clinical trials of lifileucel, Allison Betof Warner, MD, of Stanford University, Stanford, California, and Igor Puzanov, MD, of Roswell Park Comprehensive Cancer Center, Buffalo, New York, shared their expectations regarding factors that would contribute to how much a patient paid for the drug.
Given the drug’s recent approval, the logistical details are still being worked out between cancer centers and insurers regarding how much patients will pay out of pocket for lifileucel, said Dr. Betof Warner, who is assistant professor in the Department of Medicine, Division of Medical Oncology at Stanford University.
The associated costs, including the surgery that is needed to procure the TIL cells for expansion into the final drug product, will be different for each patient, she told this publication.
Patients’ costs for lifileucel will vary based on their insurance, explained Dr. Puzanov, chief of melanoma and professor of oncology at Roswell Park Comprehensive Cancer Center.
At Roswell Park, “we will work with our regionally-based payers on a case-by-case basis to seek approval for those patients we believe can most benefit from lifileucel,” he said in an interview. Preauthorization will be required, as is standard for many cancer treatments, he added.
Once payer approval is in place, Dr. Puzanov said, he did not anticipate significant delays in access for patients.
Certified centers such as the multidisciplinary team at Roswell Park are ready to treat patients now. Other centers are similarly prepared, especially those involved in the clinical trials of lifileucel, he said.
Logistics and Infrastructure
A position article and guidelines on the management of and best practices for TIL was published in the Journal for ImmunoTherapy of Cancer on February 29. The paper, of which both Dr. Betof Warner and Dr. Puzanov served as authors, noted that one of the barriers to the use of TIL cell therapy in clinical practice is the need for state-of-the art infrastructure at centers that want to offer the treatment. Scheduling, patient referrals, and surgery, as well as the production and infusion of TIL, must be organized and streamlined for successful treatment, the authors wrote.
The two supply chains involved in TIL — the transportation of the tumor tissue from the treatment center to the manufacturer and transport of the TIL infusion product back to the treatment center — must be timely and precise, they emphasized.
Docs Hope TIL Improves in Several Ways
Although the TIL technology is a breakthrough, “we hope to see even better efficacy and lower toxicity as further research looks at ways to improve on the current TIL standard,” Dr. Puzanov said.
More research and dose adjustments may impact patient costs and side effects, he noted. “I am looking to see TILs used in the front line, with or without checkpoint inhibitors.”
Research is needed to explore how to lower the chemotherapy doses and possibly the associated toxicity, he added. Finally, researchers must consider whether high-dose IL-2 therapy — given as part of the TIL cell therapy — could be replaced with other cytokines, or whether the number of doses could be lowered. Another avenue of exploration is engineering genes for cytokines into TILs, he said.
“The key is to think about TIL therapy before you need it — ideally, when the patient is still doing well on their frontline checkpoint inhibition immunotherapy,” Dr. Puzanov said in an interview. That is the time for evaluation, and specialty centers can provide an expert assessment, he said.
“We are constantly working to improve TIL therapy,” Dr. Betof Warner told this publication. More research is needed optimize the regimen to reduce side effects, which would not only make treatment easier for currently eligible patients, but might allow treatment for patients not currently eligible.
“For example, we are looking for ways to reduce the dose of preparative chemotherapy, which prepares the body for the cells to maximize their longevity and efficacy, and to reduce or eliminate the need to give IL-2 after the cell administration,” continued Dr. Betof Warner, who is also Director of Melanoma Medical Oncology, Director of Solid Tumor Cellular Therapy, and Codirector of the Pigmented Lesion and Melanoma Program at Stanford University. “We are also actively studying next-generation TIL therapies to try to increase the efficacy.”
“Lifileucel has about a 30% success rate for melanoma that has progressed after standard therapy; we are working hard to do better than that,” she noted.
In a press release, Iovance summarized the results of the trial that supported the FDA’s accelerated approval of lifileucel. In an open-label single-arm study, including multiple sites worldwide, 73 adults with unresectable or metastatic melanoma who had received at least one previous systemic therapy underwent a lymphodepleting regimen followed by treatments with fludarabine and aldesleukin. Patients then received lifileucel at a median dose of 21.1 x 109 viable cells; the recommended dose ranges from 7.5 x 109 to 72 x 109 cells.
The primary efficacy outcome was objective response rate (ORR). The ORR in the study was 31.5%, and the median time to initial lifileucel response was 1.5 months.
The clinical trials of lifileucel for which Dr. Betof Warner and Dr. Puzanov served as investigators were sponsored by Iovance.

Patients haunted by fears of living with and dying from severe lung disease
Many patients with chronic progressive pulmonary disease feel anxious and depressed as their conditions advance, as breathing becomes increasingly labored and difficult, and as performing even small daily tasks leaves them exhausted.
Disease-related mental distress can lead to increased disability, more frequent use of costly healthcare resources, higher morbidity, and elevated risk of death, investigators say.
“Individuals with severe COPD are twice as likely to develop depression than patients with mild COPD. Prevalence rates for clinical anxiety in COPD range from 13% to 46% in outpatients and 10% to 55% among inpatients,” wrote Abebaw Mengitsu Yohannes, PhD, then from Azusa Pacific University in Azusa, California, and colleagues in an article published jointly by The Journal of Family Practice and The Cleveland Clinic Journal of Medicine.
Patients with COPD may experience major depressive disorders, chronic mild depression (dysthymias), and minor depression, as well as generalized anxiety disorder, phobias, and panic disorders, the investigators say.
“Growing evidence suggests that the relationship between mood disorders — particularly depression — and COPD is bidirectional, meaning that mood disorders adversely impact prognosis in COPD, whereas COPD increases the risk of developing depression,” Yohannes et al. wrote.
Jamie Garfield, MD, professor of thoracic medicine and surgery at Temple University’s Lewis Katz School of Medicine in Philadelphia, Pennsylvania, told Chest Physician that the association between severe chronic diseases and mood disorders is well known.
“I don’t think that it’s specific to chronic lung diseases; in people with chronic heart disease or malignancies we see that coexistence of depression and anxiety will worsen the course of disease,” she said.
Dr. Johannes, who is currently a professor of physical therapy at the University of Alabama School of Health Professionals in Birmingham, said that depression and anxiety are often underdiagnosed and undertreated in patients with obstructive pulmonary diseases because the conditions can share symptoms such as dyspnea (for example, in anxiety) or fatigue (in depression).
“Therefore, unless one begins to explore further, it’s hard for physicians to be able to identify these conditions,” he said in an interview with Chest Physician.
Fears of dying (and living)
The causes of depression and anxiety among patients with obstructive pulmonary disorders are multifactorial, and may require a variety of treatment and coping strategies, according to Susann Strang, RN, PhD, and colleagues from the University of Gothenburg, Gothenburg, Sweden.
They conducted qualitative in-depth interviews with 31 men and women with stage III or IV COPD, and found that the majority of patients had anxiety associated with their disease.
“Analyses revealed three major themes: death anxiety, life anxiety, and counterweights to anxiety,” the investigators wrote in a study published in the journal Palliative and Supportive Care in 2014.
Factors contributing to anxiety surrounding death included fear of suffocation, awareness of impending death, fear of the process of death, and anxiety about being separated from loved ones.
In contrast, some patients expressed dread of living with the limitations and loneliness imposed on them by their disease — so-called “life anxiety.”
The patients also reported “counterweights” to anxiety as a way of coping. For some this involved trust in their healthcare professionals and adherence to medication, inhalers, and supplemental oxygen.
“The patients also placed hope in new treatments, better medication, surgery, stem cell treatment, or lung transplants,” Dr. Strang and colleagues reported.
Others reported avoiding talking about death, sleeping more, or using humor to “laugh off this difficult subject.”
Screening and diagnosis
Primary care practitioners are often the first health professionals that patients with COPD see, but these clinicians often don’t have the time to add screening to their already crammed schedules. In addition, “the lack of a standardized approach in diagnosis, and inadequate knowledge or confidence in assessing psychological status (particularly given the number of strategies available for screening patients for mood disorders),” can make it difficult for PCPs to detect and manage anxiety and depression in their patients with significant healthcare burdens from COPD and other obstructive lung diseases, Dr. Yohannes and colleagues noted.
In addition to commonly used screening tools for anxiety and depression such as the Primary Care Evaluation of Mental Disorders (PRIME-MD) Patient Health Questionnaire (PHQ-9), there are at least two designed to evaluate patients with lung disease: the Anxiety Inventory for Respiratory (AIR) Disease scale, developed by Dr. Yohannes and colleagues, and the COPD Anxiety Questionnaire.
The COPD Assessment Test and Clinical COPD Questionnaire, while not specifically designed to screen for mental disorders, include questions that can point to symptoms of distress in patients with COPD, Dr. Yohannes said.
“In truth I think that there are few providers who will routinely do this on all their patients in terms of quantifying the severity or the presence or absence of depression, but in my own practice I very much ask questions that align with the questions in these tools to determine whether my patient appears to have high levels of anxiety and depression,” Dr. Garfield said.
Listen to patients and families
Among the most powerful tools that clinicians have at their disposal for treating anxiety and depression in patients with chronic lung disease are their ears and their minds, said Anthony Saleh, MD, a pulmonologist at New York-Presbyterian Brooklyn Methodist Hospital in Brooklyn, New York.
“I think just listening to the patient, that’s a little bit forgotten yet so important,” he said in an interview with CHEST Physician.
“When I have someone with advanced lung disease, like idiopathic pulmonary fibrosis, like advanced emphysema, one of the most important things I think is to listen to the patient, and not just to listen to the answers of your perfunctory ‘how’s your breathing? Any chest pain?’ and those sort of rote medical questions, but listen to their thoughts, and it will given them a safe space to say ‘Hey, I’m nervous, hey I’m worried about my family, hey I’m worried if I die what’s going to happen to my wife and kids,’ and that’s something I think is invaluable.”
It’s also vital to listen to the concerns of the patients family members, who may be the primary caregivers and may share the patient’s stresses and anxieties, he said.
Pulmonary Rehabilitation
All of the experts interviewed for this article agreed that a combination of medical, social and mental health support services is important for treatment for patients with chronic obstructive lung diseases.
One of the most effective means of helping patients with both acute breathing problems and with disease-related anxiety and depression is pulmonary rehabilitation. Depending on disease severity, this multidisciplinary approach may involve exercise, patient education, psychological and nutrition counseling, and training patients how to conserve energy and adopt breathing strategies to help them better manage their symptoms.
“I think that pulmonary rehabilitation is one of the first interventions that we should be recommending for our patients,” Dr. Garfield said. “It’s physical therapy for patients with chronic lung diseases, backed by respiratory therapists, and it offers not only physical rehabilitation — improving strength and coordination, but also it helps our patients get as much as possible out of what they’ve got.”
For example, patients can be taught how to decrease their respiratory rate when they’re feeling a sense of urgency or panic. Patients can also learn how to change body positions to help them breathe more effectively when they feel that their breath is limited or restricted, she said.
“Once you’re into medical interventions, pulmonary rehab is phenomenal,” Dr. Saleh said.
Pulmonary rehabilitation helps patients to feel better about themselves and about their abilities, but “unfortunately it’s not as available as we like,” he said.
Many patients don’t live near a pulmonary rehabilitation center, and the typical two to three weekly sessions for 4-12 weeks or longer can be a significant burden for patients and caregivers, he acknowledged.
“You have to sit [with the patient] and be honest and tell them it’s a lot of diligence involved and you have to be really motivated,” he said.
Other treatment options include pharmacological therapy with antidepressants such as selective serotonin reuptake inhibitors (SSRIs) and anxiolytic agents.
“SSRIs are the current first-line drug treatment for depression, and have been shown to significantly improve depression and anxiety in patients with COPD in some, but not all, trials published to date. However, it is important to note that a diagnosis of bipolar disorder must be ruled out before initiating standard antidepressant therapy,” Dr. Johannes and colleagues wrote.
Defiant joy
Importantly, even with the burden of life with COPD, many patients found ways to experience what Strang et al. called “a defiant joy.”
“It was remarkable that when the patients were asked about what gave their lives meaning today, many talked about what had given their life meaning in the past, prior to becoming ill. In the light of the things they had lost because of the disease, many felt that their previous sources of joy no longer existed. Despite this, many still hoped to be able to get out into the fresh air, to be able to do errands, or that tomorrow might be better,” the investigators wrote.
Dr. Yohannes, Dr. Garfield, and Dr. Saleh all reported having no relevant conflicts of interest to report.

Among the most powerful tools that clinicians have at their disposal for treating anxiety and depression in patients with chronic lung disease are their ears and their minds, said Anthony Saleh, MD, a pulmonologist at New York-Presbyterian Brooklyn Methodist Hospital in Brooklyn, New York.
“I think just listening to the patient, that’s a little bit forgotten yet so important,” he said in an interview with CHEST Physician.
“When I have someone with advanced lung disease, like idiopathic pulmonary fibrosis, like advanced emphysema, one of the most important things I think is to listen to the patient, and not just to listen to the answers of your perfunctory ‘how’s your breathing? Any chest pain?’ and those sort of rote medical questions, but listen to their thoughts, and it will given them a safe space to say ‘Hey, I’m nervous, hey I’m worried about my family, hey I’m worried if I die what’s going to happen to my wife and kids,’ and that’s something I think is invaluable.”
It’s also vital to listen to the concerns of the patients family members, who may be the primary caregivers and may share the patient’s stresses and anxieties, he said.
Pulmonary Rehabilitation
All of the experts interviewed for this article agreed that a combination of medical, social and mental health support services is important for treatment for patients with chronic obstructive lung diseases.
One of the most effective means of helping patients with both acute breathing problems and with disease-related anxiety and depression is pulmonary rehabilitation. Depending on disease severity, this multidisciplinary approach may involve exercise, patient education, psychological and nutrition counseling, and training patients how to conserve energy and adopt breathing strategies to help them better manage their symptoms.
“I think that pulmonary rehabilitation is one of the first interventions that we should be recommending for our patients,” Dr. Garfield said. “It’s physical therapy for patients with chronic lung diseases, backed by respiratory therapists, and it offers not only physical rehabilitation — improving strength and coordination, but also it helps our patients get as much as possible out of what they’ve got.”
For example, patients can be taught how to decrease their respiratory rate when they’re feeling a sense of urgency or panic. Patients can also learn how to change body positions to help them breathe more effectively when they feel that their breath is limited or restricted, she said.
“Once you’re into medical interventions, pulmonary rehab is phenomenal,” Dr. Saleh said.
Pulmonary rehabilitation helps patients to feel better about themselves and about their abilities, but “unfortunately it’s not as available as we like,” he said.
Many patients don’t live near a pulmonary rehabilitation center, and the typical two to three weekly sessions for 4-12 weeks or longer can be a significant burden for patients and caregivers, he acknowledged.
“You have to sit [with the patient] and be honest and tell them it’s a lot of diligence involved and you have to be really motivated,” he said.
Other treatment options include pharmacological therapy with antidepressants such as selective serotonin reuptake inhibitors (SSRIs) and anxiolytic agents.
“SSRIs are the current first-line drug treatment for depression, and have been shown to significantly improve depression and anxiety in patients with COPD in some, but not all, trials published to date. However, it is important to note that a diagnosis of bipolar disorder must be ruled out before initiating standard antidepressant therapy,” Dr. Johannes and colleagues wrote.
Defiant joy
Importantly, even with the burden of life with COPD, many patients found ways to experience what Strang et al. called “a defiant joy.”
“It was remarkable that when the patients were asked about what gave their lives meaning today, many talked about what had given their life meaning in the past, prior to becoming ill. In the light of the things they had lost because of the disease, many felt that their previous sources of joy no longer existed. Despite this, many still hoped to be able to get out into the fresh air, to be able to do errands, or that tomorrow might be better,” the investigators wrote.
Dr. Yohannes, Dr. Garfield, and Dr. Saleh all reported having no relevant conflicts of interest to report.
Many patients with chronic progressive pulmonary disease feel anxious and depressed as their conditions advance, as breathing becomes increasingly labored and difficult, and as performing even small daily tasks leaves them exhausted.
Disease-related mental distress can lead to increased disability, more frequent use of costly healthcare resources, higher morbidity, and elevated risk of death, investigators say.
“Individuals with severe COPD are twice as likely to develop depression than patients with mild COPD. Prevalence rates for clinical anxiety in COPD range from 13% to 46% in outpatients and 10% to 55% among inpatients,” wrote Abebaw Mengitsu Yohannes, PhD, then from Azusa Pacific University in Azusa, California, and colleagues in an article published jointly by The Journal of Family Practice and The Cleveland Clinic Journal of Medicine.
Patients with COPD may experience major depressive disorders, chronic mild depression (dysthymias), and minor depression, as well as generalized anxiety disorder, phobias, and panic disorders, the investigators say.
“Growing evidence suggests that the relationship between mood disorders — particularly depression — and COPD is bidirectional, meaning that mood disorders adversely impact prognosis in COPD, whereas COPD increases the risk of developing depression,” Yohannes et al. wrote.
Jamie Garfield, MD, professor of thoracic medicine and surgery at Temple University’s Lewis Katz School of Medicine in Philadelphia, Pennsylvania, told Chest Physician that the association between severe chronic diseases and mood disorders is well known.
“I don’t think that it’s specific to chronic lung diseases; in people with chronic heart disease or malignancies we see that coexistence of depression and anxiety will worsen the course of disease,” she said.
Dr. Johannes, who is currently a professor of physical therapy at the University of Alabama School of Health Professionals in Birmingham, said that depression and anxiety are often underdiagnosed and undertreated in patients with obstructive pulmonary diseases because the conditions can share symptoms such as dyspnea (for example, in anxiety) or fatigue (in depression).
“Therefore, unless one begins to explore further, it’s hard for physicians to be able to identify these conditions,” he said in an interview with Chest Physician.
Fears of dying (and living)
The causes of depression and anxiety among patients with obstructive pulmonary disorders are multifactorial, and may require a variety of treatment and coping strategies, according to Susann Strang, RN, PhD, and colleagues from the University of Gothenburg, Gothenburg, Sweden.
They conducted qualitative in-depth interviews with 31 men and women with stage III or IV COPD, and found that the majority of patients had anxiety associated with their disease.
“Analyses revealed three major themes: death anxiety, life anxiety, and counterweights to anxiety,” the investigators wrote in a study published in the journal Palliative and Supportive Care in 2014.
Factors contributing to anxiety surrounding death included fear of suffocation, awareness of impending death, fear of the process of death, and anxiety about being separated from loved ones.
In contrast, some patients expressed dread of living with the limitations and loneliness imposed on them by their disease — so-called “life anxiety.”
The patients also reported “counterweights” to anxiety as a way of coping. For some this involved trust in their healthcare professionals and adherence to medication, inhalers, and supplemental oxygen.
“The patients also placed hope in new treatments, better medication, surgery, stem cell treatment, or lung transplants,” Dr. Strang and colleagues reported.
Others reported avoiding talking about death, sleeping more, or using humor to “laugh off this difficult subject.”
Screening and diagnosis
Primary care practitioners are often the first health professionals that patients with COPD see, but these clinicians often don’t have the time to add screening to their already crammed schedules. In addition, “the lack of a standardized approach in diagnosis, and inadequate knowledge or confidence in assessing psychological status (particularly given the number of strategies available for screening patients for mood disorders),” can make it difficult for PCPs to detect and manage anxiety and depression in their patients with significant healthcare burdens from COPD and other obstructive lung diseases, Dr. Yohannes and colleagues noted.
In addition to commonly used screening tools for anxiety and depression such as the Primary Care Evaluation of Mental Disorders (PRIME-MD) Patient Health Questionnaire (PHQ-9), there are at least two designed to evaluate patients with lung disease: the Anxiety Inventory for Respiratory (AIR) Disease scale, developed by Dr. Yohannes and colleagues, and the COPD Anxiety Questionnaire.
The COPD Assessment Test and Clinical COPD Questionnaire, while not specifically designed to screen for mental disorders, include questions that can point to symptoms of distress in patients with COPD, Dr. Yohannes said.
“In truth I think that there are few providers who will routinely do this on all their patients in terms of quantifying the severity or the presence or absence of depression, but in my own practice I very much ask questions that align with the questions in these tools to determine whether my patient appears to have high levels of anxiety and depression,” Dr. Garfield said.

How These MDs Conquered Imposter Syndrome
Do I deserve to be here? Am I doing what I’m supposed to be doing? Is anyone going to tell me if I’m terrible?
Kerri Palamara McGrath, MD, remembered worrying over these questions as chief resident at Massachusetts General Hospital, Boston, Massachusetts, in 2009. Having graduated from New York Medical College, she felt out of step with her peers from Ivy League medical schools and considered herself lucky to be there. In order to measure up, she felt she had to work twice as hard as everybody else.
But as Dr. McGrath moved through residency and spoke with other trainees, she had a realization. Her constant fears, the nagging voice in her head saying she wasn’t good enough, these issues weren’t exclusive to her; they were pervasive.
Today, Dr. McGrath is the director of the Center for Physician Well-Being at Massachusetts General Hospital. The facility aims to address physician stress and equip doctors with the tools to navigate personal and professional issues. Dr. McGrath is also a physician coach, a growing nonclinical field, helping doctors identify their own stressors, values, and measures of success. This type of internal work, Dr. McGrath feels, can help alleviate imposter syndrome, that inner refrain saying: I’ll never be good enough.
What Is Imposter Syndrome?
While not a formal medical diagnosis, imposter syndrome has been defined as «an internal experience of intellectual phoniness.» It›s considered an inability to internalize success and a tendency to attribute gains to external factors — for example, being in the right place at the right time.
“Many people describe imposter phenomena in medicine as fearing that others are going to realize that they don’t belong somewhere or question why they’re there,” said Dr. McGrath.
It’s a “fear of being found out,” added Jessi Gold, MD, a psychiatrist who treats physicians. “In many ways, imposter syndrome shows up as a conflict between the outer self — the metaphorical mask you’re ‘putting on’ [in order] to achieve, and the inner self — how you feel like you’re not measuring up.”
Dr. McGrath said she experienced imposter syndrome before her medical career even began. She applied to 26 medical schools. Only one accepted her. “The whole time, I was like, ‘This is the only school you got into, so you’re obviously not good enough,’” she recalled. Later, having been chosen by a “coveted” institution like Mass General, “you assume that, at some point, someone will realize that the gig is up, that everybody’s better than you.”
Where Does Imposter Syndrome Come From?
Dr. McGrath felt that in medicine, high expectations are often coupled with low self-compassion. “We are so hard on ourselves, and when we set our expectations so high, we’re constantly disappointed in ourselves,” she said. External markers of success — papers published, promotions, or even social media — can further fuel this.
It can feel like “striving for excellence in a sea of excellence,” Dr. McGrath added, and this can invite comparison.
Ravi Parikh, MD, a medical oncologist and physician-scientist at the University of Pennsylvania, Philadelphia, Pennsylvania, remembered struggling with imposter syndrome early in his career. As a new doctor, he had a ton of questions, and yet those above him seemed able to make weighty decisions on their own. The comparison shook his confidence. “I remember thinking that when I became an attending, I would just magically not have to run decisions by people,” said Dr. Parikh. But even then, the “magical” self-assurance didn’t materialize.
Research found that imposter syndrome is more likely to affect women and groups that are underrepresented in medicine. But overall, the incidence is remarkably high.
A 2023 survey published in the Journal of the American College of Surgeons found that 90% of female surgeons and more than two-thirds of male ones experienced imposter syndrome. In a 2023 study on medical students in JAMA, it was nearly universal; 97% reported feelings of imposter syndrome with women 1.7 times more likely to report it than men and underrepresented groups often three times more likely.
‘I’m Clearly in the Minority Here’
The term “imposter” also suggests a lack of belonging. If medicine doesn’t “look like you,” this can create feelings of pressure, like you’re “representing a whole group with your mere existence,” said Dr. Gold, “and you have to keep proving yourself.”
Chloe Slocum, MD, MPH, an assistant professor of physical medicine and rehabilitation at Harvard Medical School, Boston, Massachusetts, remembered that feeling of conspicuous “otherness.” As a resident, Dr. Slocum began presenting at national meetings and later pursued physician leadership training. Many of her counterparts at these events were older males. “At some programs early on, I’d wonder, ‘I’m clearly in the minority here; did they really make the right decision including me in this?’”
Reactions from those around you can also have an impact. Dr. McGrath — who is 5’ 2” and describes herself as looking “very young” — noted that when she started out, neither patients nor other providers thought she was a doctor.
“I have tried everything in the book to be seen, in somebody else’s eyes, as more consistent with a doctor,” she said. “I’ve dressed down. I’ve dressed up. I’ve worn heels. I’ve worn flats. I’ve worn glasses. I’ve done all the things. When you’re constantly being told you don’t look like a doctor, you start questioning yourself.”
The Emotional Toll
If that sounds mentally exhausting, it is. Research found that imposter syndrome is often linked with burnout, depression, and anxiety.
The need to prove yourself and prevent being “found out” can push some doctors toward traditional measurements of success — promotions or published work, said Dr. Gold. But “if you’re trying to achieve in ways that you don’t value,” she warned, “you’re going to burn out.”
On the other hand, intense self-doubt can also limit advancement. After all, if you don’t think you’re good enough, you may not apply for job opportunities or leadership positions.
This mental burden can persist over years and even decades. A 2020 review of studies on imposter syndrome noted that “it would be reassuring to believe that imposter symptoms decline with age.” Unfortunately, several studies indicated that they do not.
How to Manage Imposter Syndrome
While it can be difficult to overcome imposter syndrome, there are ways to work through it and make it less pervasive or intense. Here are some tips from our experts:
- Prioritize your mental health. This can be difficult for some physicians, but don’t ignore symptoms of depression, anxiety, or burnout. Untreated mental health conditions cloud the ability to reflect on some of the existential questions that will help you navigate imposter syndrome, said Dr. Gold.
- Assess how often you need validation and why. Try to identify what you›re feeling, what needs aren›t being met, and how you can meet those needs. You can then consider where to get that validation either internally or by connecting with a colleague. Dr. McGrath encourages physicians to ask, “What does success look like for me?” and can you make success more personal and meaningful. It might sound shocking, but rather than an unattainable ideal, success should be something that feels good.
- Know the power of teamwork. As Dr. Parikh eventually realized, collaborative care is a common and beneficial part of medicine — not something that makes you a less-than physician. “There’s a lot of opportunity to crowdsource the medical decision-making process in ways that increase your own confidence as a doctor,” he said.
- Practice self-compassion. Critical voices in your head add to an already hard and stressful world. This is where self-compassion comes in. “We don’t have much control over medicine, but we have control over how medicine makes us feel,” Dr. Gold said. Imagine treating yourself how you would treat a friend.
- Consider a physician coach. suggests that physician coaches can help lower rates of burnout and improve well-being, resilience, professional fulfillment, and self-worth. “Coaching looks into the future to help you envision what things would look like if you were feeling differently. It helps you explore what’s in your control and how you want to shape that,” said Dr. McGrath.
- Amplify the good. Apps and web-based tools can remind you to celebrate your own achievements. The “” exercise created by J. Bryan Sexton, PhD, at the Duke Center for Healthcare Safety & Quality for example, was documented in a . When healthcare workers reflected on three good things that happened each day for 2 weeks, they reported significant improvements in depression, burnout, and work-life balance.
- Do a values check. Dr. Gold often suggested that physicians with imposter syndrome ask themselves what they value, what medicine values, and how the two line up. Pausing to consider this can guide you toward useful strategies. If you value family life but feel like medicine doesn’t, for example, you might talk with a colleague who has navigated this conflict.
Dr. Gold added that reminding yourself of the range of options can be freeing. “There’s no ‘one career’ in medicine,” she said. “There are multiple ways to be happy in medicine; there are multiple ways to be happy outside of medicine. And you’re not a failure for the path you choose.”

The term “imposter” also suggests a lack of belonging. If medicine doesn’t “look like you,” this can create feelings of pressure, like you’re “representing a whole group with your mere existence,” said Dr. Gold, “and you have to keep proving yourself.”
Chloe Slocum, MD, MPH, an assistant professor of physical medicine and rehabilitation at Harvard Medical School, Boston, Massachusetts, remembered that feeling of conspicuous “otherness.” As a resident, Dr. Slocum began presenting at national meetings and later pursued physician leadership training. Many of her counterparts at these events were older males. “At some programs early on, I’d wonder, ‘I’m clearly in the minority here; did they really make the right decision including me in this?’”
Reactions from those around you can also have an impact. Dr. McGrath — who is 5’ 2” and describes herself as looking “very young” — noted that when she started out, neither patients nor other providers thought she was a doctor.
“I have tried everything in the book to be seen, in somebody else’s eyes, as more consistent with a doctor,” she said. “I’ve dressed down. I’ve dressed up. I’ve worn heels. I’ve worn flats. I’ve worn glasses. I’ve done all the things. When you’re constantly being told you don’t look like a doctor, you start questioning yourself.”
The Emotional Toll
If that sounds mentally exhausting, it is. Research found that imposter syndrome is often linked with burnout, depression, and anxiety.
The need to prove yourself and prevent being “found out” can push some doctors toward traditional measurements of success — promotions or published work, said Dr. Gold. But “if you’re trying to achieve in ways that you don’t value,” she warned, “you’re going to burn out.”
On the other hand, intense self-doubt can also limit advancement. After all, if you don’t think you’re good enough, you may not apply for job opportunities or leadership positions.
This mental burden can persist over years and even decades. A 2020 review of studies on imposter syndrome noted that “it would be reassuring to believe that imposter symptoms decline with age.” Unfortunately, several studies indicated that they do not.
How to Manage Imposter Syndrome
While it can be difficult to overcome imposter syndrome, there are ways to work through it and make it less pervasive or intense. Here are some tips from our experts:
- Prioritize your mental health. This can be difficult for some physicians, but don’t ignore symptoms of depression, anxiety, or burnout. Untreated mental health conditions cloud the ability to reflect on some of the existential questions that will help you navigate imposter syndrome, said Dr. Gold.
- Assess how often you need validation and why. Try to identify what you›re feeling, what needs aren›t being met, and how you can meet those needs. You can then consider where to get that validation either internally or by connecting with a colleague. Dr. McGrath encourages physicians to ask, “What does success look like for me?” and can you make success more personal and meaningful. It might sound shocking, but rather than an unattainable ideal, success should be something that feels good.
- Know the power of teamwork. As Dr. Parikh eventually realized, collaborative care is a common and beneficial part of medicine — not something that makes you a less-than physician. “There’s a lot of opportunity to crowdsource the medical decision-making process in ways that increase your own confidence as a doctor,” he said.
- Practice self-compassion. Critical voices in your head add to an already hard and stressful world. This is where self-compassion comes in. “We don’t have much control over medicine, but we have control over how medicine makes us feel,” Dr. Gold said. Imagine treating yourself how you would treat a friend.
- Consider a physician coach. suggests that physician coaches can help lower rates of burnout and improve well-being, resilience, professional fulfillment, and self-worth. “Coaching looks into the future to help you envision what things would look like if you were feeling differently. It helps you explore what’s in your control and how you want to shape that,” said Dr. McGrath.
- Amplify the good. Apps and web-based tools can remind you to celebrate your own achievements. The “” exercise created by J. Bryan Sexton, PhD, at the Duke Center for Healthcare Safety & Quality for example, was documented in a . When healthcare workers reflected on three good things that happened each day for 2 weeks, they reported significant improvements in depression, burnout, and work-life balance.
- Do a values check. Dr. Gold often suggested that physicians with imposter syndrome ask themselves what they value, what medicine values, and how the two line up. Pausing to consider this can guide you toward useful strategies. If you value family life but feel like medicine doesn’t, for example, you might talk with a colleague who has navigated this conflict.
Dr. Gold added that reminding yourself of the range of options can be freeing. “There’s no ‘one career’ in medicine,” she said. “There are multiple ways to be happy in medicine; there are multiple ways to be happy outside of medicine. And you’re not a failure for the path you choose.”

California Pushes to Expand the Universe of Abortion Care Providers
California’s efforts to expand access to abortion care are enabling more types of medical practitioners to perform certain abortion procedures — potentially a boon for patients in rural areas especially, but a source of concern for doctors’ groups that have long fought efforts to expand the role of non-physicians.
The latest move is a law that enables trained physician assistants, also known as physician associates, to perform first-trimester abortions without a supervising physician present. The measure, which passed last year and took effect Jan. 1, also lets PAs who have been disciplined or convicted solely for performing an abortion in a state where the practice is restricted apply for a license in California.
Physician assistants are now on par with nurse practitioners and certified nurse midwives trained in abortion care, who in 2022 won the ability to perform abortions without a doctor present.
The need for more abortion care practitioners is being driven by efforts in many states to gut abortion rights following the Supreme Court’s 2022 decision ending constitutional protection for the procedure. Thirty-one states have implemented abortion restrictions that range from cutting federal funding for abortion coverage to outright bans, according to the Guttmacher Institute, a research organization concerned with reproductive health.
With the new law, “there will be fewer barriers, and shorter wait times for this essential service,” said Jeremy Meis, president-elect of the California Academy of Physician Associates. While it is unclear how many of California’s 16,000 PAs will be trained in performing abortions, research shows that PAs are more likely than physicians to practice in rural areas where access to abortion is limited. More than 40% of counties in California lack clinics that provide abortion.
Comparing data from the first six months of 2020 with the same period in 2023, the number of abortions jumped from 77,030 to 92,600 a 20% increase as the state became a refuge for women seeking abortions. California has passed a suite of reproductive health laws to build in protections and increase access, and a dozen other states, including Oregon, Minnesota, and New York, have mounted similar efforts. Seventeen states, including California, now allow PAs to perform first-trimester abortions, according to the American Academy of Physician Associates.
There was little opposition to the new California law, with two physicians’ groups supporting it. But the American Medical Association, the country’s most powerful doctors’ lobby, has fought vigorously against what it calls “scope creep” — that is, changes that allow clinicians like PAs to do medical procedures independent of physicians.
“Our policy stance is the same on scope of practice expansion regardless of procedure,” noted Kelly Jakubek, the AMA’s media relations manager. The AMA’s website points to legislative victories in 2023, including striking down “legislation allowing physician assistants to practice independently without physician oversight,” in states including Arizona and New York. The AMA did not take a formal position on the California legislation. Its local chapter, the California Medical Association, took a neutral position on the legislation.
In preparation for the new law, one physician assistant at Planned Parenthood Pasadena & San Gabriel Valley began learning how to perform aspiration abortions — a procedure also known as dilation and curettage that uses gentle suction to end a pregnancy — at the end of last year. The PA, who requested anonymity due to concerns about safety, said that with abortion restrictions in place around the country, “I just think it’s really important to be able to provide a comfortable, safe, and very effective way to terminate a pregnancy for patients.”
She is now one of six PAs and midwives at her clinic who can offer aspiration abortions. To reach competency, she participated in 50 procedures and learned how to administer medication that eases pain and anxiety. Such conscious sedation, as it is known, is frequently used for first-trimester abortions. Now she, like any other advanced practice clinician who has obtained skills in performing abortions, can train her peers — another feature of the new law.
The length of time for training and the number of procedures to reach competency varies based on a practitioner’s previous experience.
“It’s encouraging this cross-profession training and collaborations, which is really important when we’re looking at increasing access to essential services,” said Jessica Dieseldorff, senior program manager of abortion services at Planned Parenthood Mar Monte in Santa Cruz.
In December, California committed $18 million to help accelerate training in abortion and reproductive care for practitioners, including PAs, through the Reproductive Health Care Access Initiative.
Dieseldorff, a nurse practitioner who trains other advanced-practice clinicians in abortion care, said that rural communities, in particular, will reap the benefits since many rely solely on physician assistants and other allied clinicians.
Reflecting on her career, she said much has changed since she became a nurse 25 years ago. At that time, she worked only as support staff to doctors providing abortions.
“When I began, medication abortions did not exist in this country,” she said, referring to the practice of using two drugs often prescribed to induce abortions. “It’s been gratifying to be able to progress and become a provider myself, provide non-stigmatizing and compassionate and safe care to patients; and now, at this stage in my career to be training others to do the same.”
