Low-dose olanzapine improves appetite in chemotherapy patients
Anorexia is a problem in approximately 50% of newly-diagnosed cancer patients, and can compromise survival, wrote study author Lakshmi Sandhya, MD, of Jawaharlal Institute of Postgraduate Medical Education and Research (JIPMER), Puducherry, India, and colleagues. In particular, patients with lung and gastrointestinal tract cancers are prone to anorexia during chemotherapy, they said. Olanzapine is a demonstrated appetite stimulant and has been used in cancer patients as a short-term antiemetic, but its use for long-term appetite stimulation has not been well-studied, they said.
In the study, published in the Journal of Clinical Oncology, the researchers randomized 124 adults aged 18 years and older to a 2.5 grams of olanzapine or placebo for 12 weeks. The participants had untreated, locally advanced, or metastatic gastric, hepatopancreaticobiliary (HPB), or lung cancers.
The median age of the participants was 55 years. The primary outcome was a weight gain greater than 5% and improved appetite based on the visual analog scale (VAS) and questionnaires. A change in nutritional status, quality of life (QOL), and chemotherapy toxicity, were secondary endpoints.
After 12 weeks, complete data were available for 58 patients in the olanzapine group and 54 in the placebo group. Of these, 60% of the olanzapine group and 9% of the placebo group met the primary endpoint of a weight gain greater than 5%. The proportion of patients with improved appetite based on VAS scores and questionnaire scores was significantly higher in olanzapine patients vs. placebo patients (43% vs. 13% and 22% vs. 4%, respectively).
In addition, 52% of the olanzapine group vs. 18% of the placebo group achieved more than 75% intake of recommended daily calories.
Most of the reported toxicities were not hematological and similar between the groups (85% for olanzapine vs. 88% for placebo). The proportion of patients with toxicities of grade 3 or higher was lower in the olanzapine group vs. the placebo group (12% vs. 37%, P = .002). Patients in the olanzapine group also reported significantly improved quality of life from baseline compared to the placebo patients.
The findings were limited by several factors including the heterogeneous cancers and treatment regimens, the lack of data on weight beyond 12 weeks, the relatively small study population, and the subjective nature of anorexia measurements, the researchers noted.
However, the results suggest that low-dose olanzapine is an effective and well-tolerated add-on intervention for the subset of patients at risk for anorexia at the start of chemotherapy, they said.
“Future studies could look at various cancers in a multicentric setting and long-term endpoints such as patient survival,” they concluded.
The study drug and placebo were funded by an intramural grant from Jawaharlal Institute of Postgraduate Medical Education and Research (JIPMER). The researchers had no financial conflicts to disclose.

FROM THE JOURNAL OF CLINICAL ONCOLOGY
The end of the telemedicine era?
I started taking care of Jim, a 68-year-old man with metastatic renal cell carcinoma back in the fall of 2018. Jim lived far from our clinic in the rural western Sierra Mountains and had a hard time getting to Santa Monica, but needed ongoing pain and symptom management, as well as follow-up visits with oncology and discussions with our teams about preparing for the end of life.
Luckily for Jim, the Centers for Medicare & Medicaid Services had relaxed the rules around telehealth because of the public health emergency, and we were easily able to provide telemedicine visits throughout the pandemic ensuring that Jim retained access to the care team that had managed his cancer for several years at that point. This would not have been possible without the use of telemedicine – at least not without great effort and expense by Jim to make frequent trips to our Santa Monica clinic.
So, you can imagine my apprehension when I received an email the other day from our billing department, informing billing providers like myself that “telehealth visits are still covered through the end of the year.” While this initially seemed like reassuring news, it immediately begged the question – what happens at the end of the year? What will care look like for patients like Jim who live at a significant distance from their providers?
The end of the COVID-19 public health emergency on May 11 has prompted states to reevaluate the future of telehealth for Medicaid and Medicare recipients. Most states plan to make some telehealth services permanent, particularly in rural areas. While other telehealth services have been extended through Dec. 31, 2024, under the Consolidated Appropriations Act of 2023.
But still, We can now see very ill patients in their own homes without imposing an undue burden on them to come in for yet another office visit. Prior to the public health emergency, our embedded palliative care program would see patients only when they were in the oncology clinic so as to not burden them with having to travel to yet another clinic. This made our palliative providers less efficient since patients were being seen by multiple providers in the same space, which led to some time spent waiting around. It also frequently tied up our clinic exam rooms for long periods of time, delaying care for patients sitting in the waiting room.
Telehealth changed that virtually overnight. With the widespread availability of smartphones and tablets, patients could stay at home and speak more comfortably in their own surroundings – especially about the difficult topics we tend to dig into in palliative care – such as fears, suffering, grief, loss, legacy, regret, trauma, gratitude, dying – without the impersonal, aseptic environment of a clinic. We could visit with their family/caregivers, kids, and their pets. We could tour their living space and see how they were managing from a functional standpoint. We could get to know aspects of our patients’ lives that we’d never have seen in the clinic that could help us understand their goals and values better and help care for them more fully.
The benefit to the institution was also measurable. We could see our patients faster – the time from referral to consult dropped dramatically because patients could be scheduled for next-day virtual visits instead of having to wait for them to come back to an oncology visit. We could do quick symptom-focused visits that prior to telehealth would have been conducted by phone without the ability to perform at the very least an observational physical exam of the patient, which is important when prescribing medications to medically frail populations.
If telemedicine goes, how will it affect outpatient palliative care?
If that goes away, I do not know what will happen to outpatient palliative care. I can tell you we will be much less efficient in terms of when we see patients. There will probably be a higher clinic burden to patients, as well as higher financial toxicity to patients (Parking in the structure attached to my office building is $22 per day). And, what about the uncaptured costs associated with transportation for those whose illness prevents them from driving themselves? This can range from Uber costs to the time cost for a patient’s family member to take off work and arrange for childcare in order to drive the patient to a clinic for a visit.
In February, I received emails from the Drug Enforcement Agency suggesting that they, too, may roll back providers’ ability to prescribe controlled substances to patients who are mainly receiving telehealth services. While I understand and fully support the need to curb inappropriate overprescribing of controlled medications, I am concerned about the unintended consequences to cancer patients who live at a remote distance from their oncologists and palliative care providers. I remain hopeful that DEA will consider a carveout exception for those patients who have cancer, are receiving palliative care services, or are deemed to be at the end of life, much like the chronic opioid guidelines developed by the Centers for Disease Control and Prevention have done.
Telemedicine in essential care
Back to Jim. Using telehealth and electronic prescribing, our oncology and palliative care programs were able to keep Jim comfortable and at home through the end of his life. He did not have to travel 3 hours each way to get care. He did not have to spend money on parking and gas, and his daughter did not have to take days off work and arrange for a babysitter in order to drive him to our clinic. We partnered with a local pharmacy that was willing to special order medications for Jim when his pain became worse and he required a long-acting opioid. We partnered with a local home health company that kept a close eye on Jim and let us know when he seemed to be declining further, prompting discussions about transitioning to hospice.
I’m proud of the fact that our group helped Jim stay in comfortable surroundings and out of the clinic and hospital over the last 6 months of his life, but that would never have happened without the safe and thoughtful use of telehealth by our team.
Ironically, because of a public health emergency, we were able to provide efficient and high-quality palliative care at the right time, to the right person, in the right place, satisfying CMS goals to provide better care for patients and whole populations at lower costs.

Financial navigators saved about $2,500 per cancer patient
Cancer patients in the United States face complex financial issues in navigating with medical insurance companies to cover their care. This “financial toxicity” has come to be regarded as a side effect of cancer treatment.
Patients with hematologic malignancies may be particularly vulnerable to financial toxicity, owing to the nature of their treatment, which often includes bone marrow transplantation, lengthy hospital stays, and prolonged intensive follow-up, as well as potential treatment-related complications, such as graft vs. host disease.
The results from this small study suggest that using an oncology financial navigator could be helpful. But not all cancer patients have access to such a person, explained lead author Jean S. Edward, PhD, RN, associate professor in the college of nursing at the University of Kentucky, Lexington.
“Unfortunately, it’s not as common as we would like, especially in underserved areas with patient and caregiver populations that need it the most,” she said. Dr. Edward is hopeful that the results from this study, even though it is small, might help to boost use of this intervention. “OFN [oncology financial navigation] is not necessarily a cutting-edge program or ‘novel’ intervention, but the lack of programs and limitations in implementing in cancer centers does make it a gap in practice,” Dr. Edward told this news organization.
“There are gaps in evidence on how to incorporate an oncology financial navigator in current workflows and sustainability of positions, but as our study has shown, the return on investment to the health care system and/or financial benefits to patients/caregivers could help cover the cost of implementing such programs,” she said.
The study was published in JCO Oncology Practice.
The intervention used in this study, Coverage and Cost-of-Care Links (CC Links), was designed specifically to address financial toxicity among patients with hematologic cancers.
The study’s primary outcomes were defined as improvements in financial distress as well as in physical and mental quality of life.
A total of 54 patients and 32 caregivers completed the intervention and pre-/postintervention surveys. More than half of participants were women. The average age was 63 years. Less than a quarter of the patients were employed (23%), about one-third had income that was below the federal poverty level, and almost all had insurance. About 59% of the caregivers were employed.
The navigators’ functions included screening for financial toxicity using FACIT-Comprehensive Score for Financial Toxicity (COST) and the National Comprehensive Cancer Network’s Distress Thermometer and Problem List. They also helped patients to estimate cost of care, assessed health insurance coverage, and connected patients/caregivers with disease-specific resources and other external assistance programs, among other things.
Participants had an average of three in-person meetings and five telephone interactions with the financial navigator. The most common concern was in regard to high out-of-pocket costs. The most frequently provided services from the navigator were helping with financial assistance programs and grant applications. Overall, the navigator was able to obtain $124,600 in financial benefits for 48 participants, as well as money for travel ($24,000), urgent needs ($16,000), patient financial assistance ($9,100), and copay assistance grants ($75,500).
With regard to scores on the screening tools, the only significant change from pre- to postintervention was in the psychological response score, or COST. It decreased by an average of 2.30 points (P = .019; Hedges’ g = 0.33). For caregivers, there was a significant improvement in COST (average decrease, 2.97 points; P = .021; g = 0.43), material condition scores (average decrease, 0.63 points; P = .031; g = 0.39), and total financial toxicity scores (average decrease, 0.13 points; P = .041; g = 0.37).
Most of the participants gave the intervention high ratings for acceptability (89%) and appropriateness (88%).
“Standardized screening for financial toxicity in cancer care settings is essential to support early identification of financial needs that serve as barriers to care,” the authors conclude. “Close collaboration and coordination with existing services and workflows are essential for the seamless integration of OFN interventions within health systems and to help facilitate contact and communication with participants.”
The study was supported by the National Cancer Institute; the University of Kentucky’s Markey Cancer Center; the Research Communications Office of the Patient Oriented and Population Science Shared Resource Facilities; Joan Scales, LCSW, and the Psych-Oncology Program at the University of Kentucky Markey Cancer Center; and UK HealthCare’s Patient Financial Services. Dr. Edward has disclosed no relevant financial relationships.

Cancer patients in the United States face complex financial issues in navigating with medical insurance companies to cover their care. This “financial toxicity” has come to be regarded as a side effect of cancer treatment.
Patients with hematologic malignancies may be particularly vulnerable to financial toxicity, owing to the nature of their treatment, which often includes bone marrow transplantation, lengthy hospital stays, and prolonged intensive follow-up, as well as potential treatment-related complications, such as graft vs. host disease.
The results from this small study suggest that using an oncology financial navigator could be helpful. But not all cancer patients have access to such a person, explained lead author Jean S. Edward, PhD, RN, associate professor in the college of nursing at the University of Kentucky, Lexington.
“Unfortunately, it’s not as common as we would like, especially in underserved areas with patient and caregiver populations that need it the most,” she said. Dr. Edward is hopeful that the results from this study, even though it is small, might help to boost use of this intervention. “OFN [oncology financial navigation] is not necessarily a cutting-edge program or ‘novel’ intervention, but the lack of programs and limitations in implementing in cancer centers does make it a gap in practice,” Dr. Edward told this news organization.
“There are gaps in evidence on how to incorporate an oncology financial navigator in current workflows and sustainability of positions, but as our study has shown, the return on investment to the health care system and/or financial benefits to patients/caregivers could help cover the cost of implementing such programs,” she said.
The study was published in JCO Oncology Practice.
The intervention used in this study, Coverage and Cost-of-Care Links (CC Links), was designed specifically to address financial toxicity among patients with hematologic cancers.
The study’s primary outcomes were defined as improvements in financial distress as well as in physical and mental quality of life.
A total of 54 patients and 32 caregivers completed the intervention and pre-/postintervention surveys. More than half of participants were women. The average age was 63 years. Less than a quarter of the patients were employed (23%), about one-third had income that was below the federal poverty level, and almost all had insurance. About 59% of the caregivers were employed.
The navigators’ functions included screening for financial toxicity using FACIT-Comprehensive Score for Financial Toxicity (COST) and the National Comprehensive Cancer Network’s Distress Thermometer and Problem List. They also helped patients to estimate cost of care, assessed health insurance coverage, and connected patients/caregivers with disease-specific resources and other external assistance programs, among other things.
Participants had an average of three in-person meetings and five telephone interactions with the financial navigator. The most common concern was in regard to high out-of-pocket costs. The most frequently provided services from the navigator were helping with financial assistance programs and grant applications. Overall, the navigator was able to obtain $124,600 in financial benefits for 48 participants, as well as money for travel ($24,000), urgent needs ($16,000), patient financial assistance ($9,100), and copay assistance grants ($75,500).
With regard to scores on the screening tools, the only significant change from pre- to postintervention was in the psychological response score, or COST. It decreased by an average of 2.30 points (P = .019; Hedges’ g = 0.33). For caregivers, there was a significant improvement in COST (average decrease, 2.97 points; P = .021; g = 0.43), material condition scores (average decrease, 0.63 points; P = .031; g = 0.39), and total financial toxicity scores (average decrease, 0.13 points; P = .041; g = 0.37).
Most of the participants gave the intervention high ratings for acceptability (89%) and appropriateness (88%).
“Standardized screening for financial toxicity in cancer care settings is essential to support early identification of financial needs that serve as barriers to care,” the authors conclude. “Close collaboration and coordination with existing services and workflows are essential for the seamless integration of OFN interventions within health systems and to help facilitate contact and communication with participants.”

Surgery for early breast cancer can worsen frailty in older women
according to a new study.
About 1 in 5 experienced clinically significant deterioration in frailty status after treatment, the study team found. Women at highest risk for declines in frailty following treatment had “robust” baseline frailty status at diagnosis and underwent more invasive mastectomy compared with lumpectomy.
The fact that “robust” older women were more likely to become frail after locoregional therapy suggests that “thoughtful treatment decisions should be undertaken in all older women, not simply those who have frailty at diagnosis,” said the investigators, led by Christina Minami, MD, of Dana-Farber/Brigham and Women’s Cancer Center in Boston.
The study findings emphasize that there is no one-size-fits-all approach to breast cancer treatment in the elderly, said Sarah P. Cate, MD, director, Breast Surgery Quality Program, Mount Sinai Health System, New York, who wasn’t involved in the research. “Some patients will sail through a surgery, and others are severely affected by it.”
The study was published online in JAMA Surgery.
Given the growing number of older adults with breast cancer, understanding how age-related syndromes, such as frailty, may alter cancer outcomes and how cancer treatments change aging trajectories remains important.
To investigate, Dr. Minami and colleagues used Surveillance, Epidemiology, and End Results Medicare data to identify 31,084 women (mean age, 73) who had been diagnosed with ductal carcinoma in situ (DCIS) or stage I HR-positive, ERBB2-positive breast cancer and who underwent surgery (23% mastectomy, 77% lumpectomy) and radiation therapy.
Worsening frailty status was defined as a decline of 0.03 or greater in a validated frailty index from the time of diagnosis to 1 year. This level of change has been linked to greater mortality risk and greater cost of care.
Frailty status at diagnosis was “robust” in 56% of the women, prefrail in 40%, mildly frail in 4%, and moderately to severely frail in 0.3%.
According to the researchers, 21.4% of the women experienced clinically significant declines in their frailty status after treatment. These declines occurred in 25% of women who underwent mastectomy and 20% of those who underwent lumpectomy.
After adjusting for covariates, there was a higher likelihood of worsening frailty among women who were robustly frail at baseline, in comparison with those who were moderately to severely frail at baseline (odds ratio, 6.12), and in those who underwent mastectomy vs. lumpectomy (OR, 1.31).
Older age and race were also linked to worsening frailty status following treatment. Compared with younger women (aged 65-74 years), older women were more likely to experience worsening frailty (OR, 1.21 for women aged 75-79; OR, 1.53 for those aged 80-84; OR, 1.94 for those aged 85 and older). In addition, Black women were more likely than non-Hispanic White women to experience worsening frailty after treatment (OR, 1.12).
“Previous studies have documented lasting declines in functional status after surgery in older patients with breast cancer, but breast cancer treatment has not been implicated in worsening frailty to date,” Dr. Minami and colleagues explain. But “given the substantial proportion of women experiencing worsening frailty and the significant difference by breast surgery type, frailty status as a cancer therapy outcome should be further explored.” In addition, “tailoring locoregional therapy intensity in this population is important,” they write.
Dr. Cate explained that randomized clinical trials such as COMET and LORIS, which explore the monitoring of patients with DCIS in lieu of active treatment, “will likely make a big impact on this population, as we currently do not have randomized controlled data for observation of breast cancer.”
Dr. Cate added as well that assessing a patient’s ECOG [Eastern Cooperative Oncology Group] performance status is vital “to determine who can really tolerate a breast cancer surgery” and that opting for antiestrogens, such as aromatase inhibitors, which can keep cancer at bay for years, “may be preferable for many older patients.”
The study was funded by Brigham and Women’s Hospital’s Department of Surgery’s Beal Fellowship. Dr. Minami and Dr. Cate have disclosed no relevant financial relationships.

COVID can mimic prostate cancer symptoms
This patient has a strong likelihood of aggressive prostate cancer, right? If that same patient also presents with severe, burning bone pain with no precipitating trauma to the area and rest and over-the-counter painkillers are not helping, you’d think, “check for metastases,” right?
That patient was me in late January 2023.
As a research scientist member of the American Urological Association, I knew enough to know I had to consult my urologist ASAP.
With the above symptoms, I’ll admit I was scared. Fortunately, if that’s the right word, I was no stranger to a rapid, dramatic spike in PSA. In 2021 I was temporarily living in a new city, and I wanted to form a relationship with a good local urologist. The urologist that I was referred to gave me a thorough consultation, including a vigorous digital rectal exam (DRE) and sent me across the street for a blood draw.
To my shock, my PSA had spiked over 2 points, to 9.9 from 7.8 a few months earlier. I freaked. Had my 3-cm tumor burst out into an aggressive cancer? Research on PubMed provided an array of studies showing what could cause PSA to suddenly rise, including a DRE performed 72 hours before the blood draw.1 A week later, my PSA was back down to its normal 7.6.
But in January 2023, I had none of those previously reported experiences that could suddenly trigger a spike in PSA, like a DRE or riding on a thin bicycle seat for a few hours before the lab visit.
The COVID effect
I went back to PubMed and found a new circumstance that could cause a surge in PSA: COVID-19. A recent study2 of 91 men with benign prostatic hypertrophy by researchers in Turkey found that PSA spiked from 0 to 5 points during the COVID infection period and up to 2 points higher 3 months after the infection had cleared. I had tested positive for COVID-19 in mid-December 2022, 4 weeks before my 9.9 PSA reading.
Using Google translate, I communicated with the team in Turkey and found out that the PSA spike can last up to 6 months.
That study helps explain why my PSA dropped over 1.5 points to 8.5 just 2 weeks after the 9.9 reading, with the expectation that it would return to its previous normal of 7.8 within 6 months of infection with SARS-CoV-2. To be safe, my urologist scheduled another PSA test in May, along with an updated multiparametric MRI, which may be followed by an in-bore MRI-guided biopsy of the 3-cm tumor if the mass has enlarged.
COVID-19 pain
What about my burning bone pain in my upper right humerus and right rotator cuff that was not precipitated by trauma or strain? A radiograph found no evidence of metastasis, thank goodness. And my research showed that several studies3 have found that COVID-19 can cause burning musculoskeletal pain, including enthesopathy, which is what I had per the radiology report. So my PSA spike and searing pain were likely consequences of the infection.
To avoid the risk for a gross misdiagnosis after a radical spike in PSA, the informed urologist should ask the patient if he has had COVID-19 in the previous 6 months. Overlooking that question could lead to the wrong diagnostic decisions about a rapid jump in PSA or unexplained bone pain.

Depression tied to inflammation and survival in lung cancer
suggests a new study.
The findings underscore the importance of assessing and treating depression in patients with cancer, particularly given the high rate of depression among those with lung cancer versus other types of cancer, the investigators said.
The study involved 186 patients with newly diagnosed stage IV non–small cell lung cancer (NSCLC), of whom 35% had self-reported moderate to severe depressive symptoms.
Depression was reliably associated with lung-relevant systemic inflammation responses (SIRs), which included neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and Advanced Lung Cancer Inflammation Index (ALI) score.
These SIRs were prognostic for 2-year OS.
Overall mortality at 2 years was 61%. Higher NLRs and PLRs and lower ALI scores all predicted worse OS (hazard ratio, 1.91, 2.08, and 0.53, respectively).
The findings were published online in PLoS ONE (2023 Feb 24.
“These patients with high levels of depression are at much higher risk for poor outcomes,” but the key finding was that patients with the highest depression levels were driving the relationship, lead author Barbara Andersen, PhD, professor of psychology at Ohio State University, Columbus, stated in a press release.
“It was patients with high depression levels who had strikingly higher inflammation levels, and that is what really drove the correlation we saw,” she explained.
For example, 56% of patients with no depression symptoms or only mild depression symptoms had a PLR above the cutoff for dangerous levels of inflammation, compared with 42% whose PLR was below the cutoff. However, among those with high depression levels, 77% and 23% had a PLR above and below the cutoff, respectively.
“These highly depressed patients were 1.3-3 times more likely to have high inflammation levels, even after controlling for other factors related to inflammation biomarker levels, including demographics and smoking status,” Dr. Andersen noted.
“Depression levels may be as important or even more important than other factors that have been associated with how people fare with lung cancer,” she suggested.
In a previous study, the team controlled for baseline depression and found that “the trajectory of depression from diagnosis through 2 years (18 assessments) predicted NSCLC patients’ survival (HR, 1.09), above and beyond baseline depression, sociodemographics, smoking status, cell type, and receipt of targeted treatments and immunotherapies.”
“Taken together, data support psychological, behavioral, and biologic toxicities of depression capable of influencing treatment response and/or survival,” they wrote.
“The results may help explain why a substantial portion of lung cancer patients fail to respond to new immunotherapy and targeted treatments that have led to significantly longer survival for many people with the disease,” Dr. Andersen said.
The investigators concluded that “intensive study of depression among patients with NSCLC, combined with measures of cell biology, inflammation, and immunity, is needed to extend these findings and discover their mechanisms, with the long-term aim to improve patients’ quality of life, treatment responses, and longevity.”
This study was funded by the Ohio State University Comprehensive Cancer Center and Pelotonia through grants to individual authors. Dr. Andersen reported having no relevant disclosures.

“Depression levels may be as important or even more important than other factors that have been associated with how people fare with lung cancer,” she suggested.
In a previous study, the team controlled for baseline depression and found that “the trajectory of depression from diagnosis through 2 years (18 assessments) predicted NSCLC patients’ survival (HR, 1.09), above and beyond baseline depression, sociodemographics, smoking status, cell type, and receipt of targeted treatments and immunotherapies.”
“Taken together, data support psychological, behavioral, and biologic toxicities of depression capable of influencing treatment response and/or survival,” they wrote.
“The results may help explain why a substantial portion of lung cancer patients fail to respond to new immunotherapy and targeted treatments that have led to significantly longer survival for many people with the disease,” Dr. Andersen said.
The investigators concluded that “intensive study of depression among patients with NSCLC, combined with measures of cell biology, inflammation, and immunity, is needed to extend these findings and discover their mechanisms, with the long-term aim to improve patients’ quality of life, treatment responses, and longevity.”
This study was funded by the Ohio State University Comprehensive Cancer Center and Pelotonia through grants to individual authors. Dr. Andersen reported having no relevant disclosures.

suggests a new study.
The findings underscore the importance of assessing and treating depression in patients with cancer, particularly given the high rate of depression among those with lung cancer versus other types of cancer, the investigators said.
The study involved 186 patients with newly diagnosed stage IV non–small cell lung cancer (NSCLC), of whom 35% had self-reported moderate to severe depressive symptoms.
Depression was reliably associated with lung-relevant systemic inflammation responses (SIRs), which included neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and Advanced Lung Cancer Inflammation Index (ALI) score.
These SIRs were prognostic for 2-year OS.
Overall mortality at 2 years was 61%. Higher NLRs and PLRs and lower ALI scores all predicted worse OS (hazard ratio, 1.91, 2.08, and 0.53, respectively).
The findings were published online in PLoS ONE (2023 Feb 24.
“These patients with high levels of depression are at much higher risk for poor outcomes,” but the key finding was that patients with the highest depression levels were driving the relationship, lead author Barbara Andersen, PhD, professor of psychology at Ohio State University, Columbus, stated in a press release.
“It was patients with high depression levels who had strikingly higher inflammation levels, and that is what really drove the correlation we saw,” she explained.
For example, 56% of patients with no depression symptoms or only mild depression symptoms had a PLR above the cutoff for dangerous levels of inflammation, compared with 42% whose PLR was below the cutoff. However, among those with high depression levels, 77% and 23% had a PLR above and below the cutoff, respectively.
“These highly depressed patients were 1.3-3 times more likely to have high inflammation levels, even after controlling for other factors related to inflammation biomarker levels, including demographics and smoking status,” Dr. Andersen noted.

Increased cancer in military pilots and ground crew: Pentagon
“Military aircrew and ground crew were overall more likely to be diagnosed with cancer, but less likely to die from cancer compared to the U.S. population,” the report concludes.
The study involved 156,050 aircrew and 737,891 ground crew. Participants were followed between 1992 and 2017. Both groups were predominantly male and non-Hispanic.
Data on cancer incidence and mortality for these two groups were compared with data from groups of similar age in the general population through use of the Surveillance, Epidemiology, and End Results (SEER) Database of the National Cancer Institute.
For aircrew, the study found an 87% higher rate of melanoma, a 39% higher rate of thyroid cancer, a 16% higher rate of prostate cancer, and a 24% higher rate of cancer for all sites combined.
A higher rate of melanoma and prostate cancer among aircrew has been reported previously, but the increased rate of thyroid cancer is a new finding, the authors note.
The uptick in melanoma has also been reported in studies of civilian pilots and cabin crew. It has been attributed to exposure to hazardous ultraviolet and cosmic radiation.
For ground crew members, the analysis found a 19% higher rate of cancers of the brain and nervous system, a 15% higher rate of thyroid cancer, a 9% higher rate of melanoma and of kidney and renal pelvis cancers, and a 3% higher rate of cancer for all sites combined.
There is little to compare these findings with: This is the first time that cancer risk has been evaluated in such a large population of military ground crew.
Lower rates of cancer mortality
In contrast to the increase in cancer incidence, the report found a decrease in cancer mortality.
When compared with a demographically similar U.S. population, the mortality rate among aircrew was 56% lower for all cancer sites; for ground crew, the mortality rate was 35% lower.
However, the report authors emphasize that “it is important to note that the military study population was relatively young.”
The median age at the end of follow-up for the cancer incidence analysis was 41 years for aircrew and 26 years for ground crew. The median age at the end of follow-up for the cancer mortality analysis was 48 years for aircrew and 41 years for ground crew.
“Results may have differed if additional older former Service members had been included in the study, since cancer risk and mortality rates increase with age,” the authors comment.
Other studies have found an increase in deaths from melanoma as well as an increase in the incidence of melanoma. A meta-analysis published in 2019 in the British Journal of Dermatology found that airline pilots and cabin crew have about twice the risk of melanoma and other skin cancers than the general population. Pilots are also more likely to die from melanoma.
Further study underway
The findings on military air and ground crew come from phase 1 of a study that was required by Congress in the 2021 defense bill. Because the investigators found an increase in the incidence of cancer, phase 2 of the study is now necessary.
The report authors explain that phase 2 will consist of identifying the carcinogenic toxicants or hazardous materials associated with military flight operations; identifying operating environments that could be associated with increased amounts of ionizing and nonionizing radiation; identifying specific duties, dates of service, and types of aircraft flown that could have increased the risk for cancer; identifying duty locations associated with a higher incidence of cancers; identifying potential exposures through military service that are not related to aviation; and determining the appropriate age to begin screening military aircrew and ground crew for cancers.

FDA strengthens mammography regulations: Final rule
A final rule, updating the regulations issued under the Mammography Quality Standards Act of 1992, requires that mammography facilities notify patients about the density of their breasts, strengthens the FDA’s oversight of facilities, and provides guidance to help physicians better categorize and assess mammograms, according to a March 9 press release.
The rule requires implementation of the changes within 18 months.
According to the final rule document, the updates are “intended to improve the delivery of mammography services” in ways that reflect changes in mammography technology, quality standards, and the way results are categorized, reported, and communicated to patients and providers.
For instance, mammography reports must include an assessment of breast density to provide greater detail on the potential limitations of the mammogram results and allow patients and physicians to make more informed decisions, such as the possibility of additional imaging for women with dense breast tissue.
“Today’s action represents the agency’s broader commitment to support innovation to prevent, detect and treat cancer,” said Hilary Marston, MD, MPH, FDA’s chief medical officer, in the agency’s press release. The FDA remains “committed to advancing efforts to improve the health of women and strengthen the fight against breast cancer.”

Breast cancer surgery timing matters, but is faster always better?
according to findings from a case series.
With no national quality metrics delineating optimal breast cancer surgery timing, the researchers recommend surgery before 8 weeks from breast cancer diagnosis.
“This time interval does not appear to have a detrimental association with cancer outcomes and allows for multidisciplinary care,” the researchers, led by Alyssa A. Wiener, MD, from University of Wisconsin–Madison, said.
But, in an accompanying editorial, two surgical oncologists questioned whether faster surgery is always better.
“Efficiency might associate with quality, but doesn’t always ensure it,” Rita Mukhtar, MD, and Laura Esserman, MD, with the division of surgical oncology, University of California, San Francisco, said.
The study and editorial were published online in JAMA Surgery.
Optimal timing for surgery?
Some studies have found worse survival outcomes for women who experience delays between breast cancer diagnosis and surgical treatment, but the optimal window for surgery and the point at which surgery becomes less advantageous remain unknown.
Using the National Cancer Database, Dr. Wiener and colleagues identified 373,334 women (median age, 61) who were diagnosed with stage I to stage III ductal or lobular breast cancer from 2010 to 2014 and followed up through 2019.
All women underwent surgery as their first course of treatment. Patients with prior breast cancer, those who had neoadjuvant or experimental therapy or missing receptor information, and those who were diagnosed with breast cancer on the date of their primary surgery were excluded.
Most patients had timely surgery. The median time to surgery was 30 days, and 88% of patients underwent surgery before the 57-day time point.
Only 12% of patients had surgery more than 8 weeks after their diagnosis. Factors associated with longer times to surgery included age younger than 45, having Medicaid or no insurance, and lower household income.
The overall 5-year survival for the cohort was high at 90%. On multivariable analysis, the researchers found no statistically significant association between time to surgery and overall survival when surgery was performed between 0 and 8 weeks.
However, women who had surgery 9 or more weeks after diagnosis had a significantly higher rate of death within 5 years, compared with those who had surgery performed between 0 and 4 weeks (hazard ratio, 1.15; P < .001). Performing surgery up to 9 weeks (57-63 days) post diagnosis also did not appear to be negatively associated with survival.
This study “highlights that time to treatment of breast cancer is important,” said Sarah P. Cate, MD, director, Breast Surgery Quality Program, Mount Sinai Health System, New York, who wasn’t involved in the study. “Surgery is only one-third of the treatment of breast cancer, so these patients who had longer delays to the OR may have also not started their postsurgery treatments in time.”
In addition, the study found that socioeconomic status – Medicaid or uninsured status and lower household incomes – was associated with longer times to surgery.
“Socioeconomic factors like these may be independently associated with worse outcomes and may contribute to some of the disparities in cancer outcomes observed for resource-limited patients due to delayed care,” the authors said.
Identifying 8 weeks as a goal for time to surgery can help uncover delays associated with socioeconomic factors and provide adequate time for decision-making, the researchers noted.
Is faster always better?
Dr. Wiener and colleagues cautioned, however, that their findings should be considered “hypothesis generating,” given that decision-making surrounding breast cancer surgery is complex.
Importantly, the authors noted, tumor characteristics, such as tumor size, nodal status, and receptor subtype, appeared to have a pronounced impact on overall survival, compared with timing of surgery. For instance, compared with a tumor size of 2 cm or fewer, larger tumors – those > 2 cm to ≤ 5 cm and > 5 cm – were associated with worse survival (HR, 1.80 and 2.62, respectively).
“This highlights that tumor biology is the primary driver of patients’ breast cancer outcomes,” the authors noted.
In an accompanying editorial, two surgical oncologists highlighted that faster may not always be better.
For instance, Dr. Mukhtar and Dr. Esserman explained, if a patient with a large node-positive, triple-negative breast cancer receives surgery within a week of diagnosis, “one must question whether this timely care represents quality care, as the opportunity to understand tumor response and affect breast cancer survival has been lost.”
The editorialists noted that time to surgery might also matter very little for indolent, screen-detected cancers, and time to treatment start might matter a lot for fast-growing, interval cancers.
In addition, they questioned whether including the socioeconomic factors highlighted in the overall model would “mitigate the association between time to surgery and survival seen in this study.”
Overall, “operating too soon could indicate lack of quality, while operating too late perhaps reflects lack of access to care,” the editorialists said.
This study was supported by grants from the National Cancer Institute and the National Institutes of Health. Dr. Wiener and Dr. Cate report no relevant financial relationships. Dr. Esserman is a member of the Blue Cross Medical advisory panel, is a board member of the Quantum Leap Healthcare Collaborative, and leads an investigator-initiated vaccine trial for high-risk ductal carcinoma in situ, which is funded by Merck.

HER2-low breast cancer is not a separate clinical entity: Study
Much attention has been focused recently on the idea that breast cancer with a low expression of HER2 can be treated with HER2-targeted agents. Not surprisingly, manufacturers of these drugs have pounced on this idea, as it opens up a whole new patient population: previously these drugs were only for tumors with a high HER2 expression.
There is a large potential market at stake: HER2-low (also referred to as ERBB2-low), as defined by a score of 0 to 3+ on immunohistochemistry (IHC), is seen in approximately 50%-60% of all breast cancers
However, The authors argued that it actually it represents a series of biological differences from HER2-negative disease that do not have a strong bearing on outcomes.
The analysis was published online in JAMA Oncology.
For the study, researchers from the University of Chicago examined data on more than 1.1 million breast cancer patients recorded as HER2-negative in the U.S. National Cancer Database, and re-classified almost two thirds as HER2-low on further analysis.
They found that HER2-low status was associated with higher estrogen receptor (ER) expression, as well as a lower rate of pathologic complete response, compared with HER2-negative disease. It was also linked to an improvement in overall survival on multivariate analysis of up to 9% in advance stage triple negative tumors.
“However, the clinical significance of these differences is questionable,” the researchers commented.
HER2-low status alone “should not influence neoadjuvant treatment decisions with currently approved regimens,” they added.
These results “do not support classification of HER2-low breast cancer as a distinct clinical subtype,” the team concluded.
Not necessarily, according to Giuseppe Curigliano, MD, PhD, director of the new drugs and early drug development for innovative therapies division at the European Institute of Oncology, Milan. He argued the opposite case, that HER2-low is a separate clinical entity, in a recent debate on the topic held at the 2022 San Antonio Breast Cancer Symposium.
In a comment, Dr. Curigliano said that a “major strength” of the current study is its large patient cohort, which reflects the majority of cancer diagnoses in the United States, but that it nevertheless has “important limitations that should be considered when interpreting the results.”
The inclusion of only overall survival in the dataset limits the ability to make associations between HER2-low status and cancer-specific prognosis, as “survival may lag years behind recurrence.”
The lack of centralized assessment of IHC results is also an issue, as “some of the results may be associated with regional variation in practice of classifying cases as HER2 0 versus HER2 1+.”
“In my opinion, this is a great limitation,” he said, in being able to conclude that there is “no prognostic difference between ERBB2-low and -negative patients.”
He also noted that, from a molecular point of view, “the key determinant of the gene expression profile is the expression of hormone receptors, [and] if we perform a correction for hormone receptor expression, only marginal differences in gene expression are found” between HER2-low and HER2-negative tumors.
“Similarly, large genomic studies have identified no specific and consistent difference in genomic profiles,” Dr. Curigliano said, and so, HER2-low disease, “as currently defined, should not be considered a distinct molecular entity, but rather a heterogeneous group of tumors, with biology primarily driven by hormone receptor expression.”
Analysis quoted by both sides
Senior author of the new analysis, Frederick M. Howard, MD, from the section of hematology-oncology in the department of medicine at the University of Chicago, said that his team’s work was quoted by both sides of the debate at SABCS 2022.
This reflects the fact that, while differences between ERBB2-low and -negative are present, it is “questionable how clinically significant those differences are,” he said in an interview. It’s a matter of “the eye of the beholder.”
Dr. Howard does not think that clinicians are going to modify standard treatment regimens based solely on HER2-low status, and that low expression of the protein “is probably just a reflection of some underlying biologic processes.”
Dr. Howard agreed with Dr. Curigliano that a “caveat” of their study is that the IHC analyses were performed locally, especially as it has shown that there can be discordance between pathologists in around 40% of cases, and that the associations they found might therefore be “strengthened” by more precise quantification of HER2 expression.
“But, even then,” Dr. Howard continued, “I doubt that [ERBB2-low status] is going to be that strong a prognostic factor.”
He believes that advances in analytic techniques will, in the future, allow tumors to be characterized more precisely, and it may be that HER2-low tumors end up being called something else in 5 years.
Renewed interest in this subgroup
In their paper, Dr. Howard and colleagues pointed out that, as a group, HER2-low tumors are heterogeneous, with HER2-low found in both hormone receptor–positive and triple-negative breast cancers. Also, various studies have come to different conclusions about what HER2 low means prognostically, with conclusions ranging from negative to neutral and to positive prognoses.
However, new research has shown that patients with HER2-low tumors can benefit from HER2-targeted drugs. In particular, the recent report that the antibody-drug conjugate trastuzumab deruxtecan doubled progression-free survival versus chemotherapy in ERBB2-low tumors led to “renewed interest in the subgroup,” the researchers noted.
To examine this subgroup further, they embarked on their analysis. Examining the National Cancer Database, they gathered information on more than 1.1 million U.S. patients diagnosed with HER2-negative invasive breast cancer in the 10-year period 2010-2019, and for whom IHC results were available.
The patients were reclassified as having HER2-low disease if they had an IHC score of 1+, or 2+ with a negative in situ hybridization test, while those with an IHC score of 0 were deemed to be HER2-negative. They were followed up until Nov. 30, 2022.
These patients had a mean age of 62.4 years, and 99.1% were female. The majority (78.6%) were non-Hispanic white. HER2-low was identified in 65.5% of the cohort, while 34.5% were HER2-negative.
The proportion of HER2-low disease was lower in non-Hispanic black (62.8%) and Hispanic (61%) patients than in non-Hispanic White patients, at 66.1%.
HER2-low disease was also more common in hormone receptor–positive than triple-negative tumors, at just 51.5%, rising to 58.6% for progesterone receptor–positive, ER-negative, and 69.1% for PR-positive, ER-positive tumors.
Multivariate logistic regression analysis taking into account age, sex, race and ethnicity, comorbidity score, and treatment facility type, among other factors, revealed that the likelihood of HER2-low disease was significantly with increased ER expression, at an adjusted odds ratio of 1.15 for each 10% increase (P < .001).
Non-Hispanic Black, Asian, and Pacific Islander patients had similar rates of HER2-low disease as non-Hispanic White patients after adjustment, whereas Native American patients had an increased rate, at an aOR of 1.22 (P < .001), and Hispanic patients had a lower rate, at an aOR of 0.85 (P < .001).
HER2-low status was associated with a slightly reduced likelihood of having a pathologic complete response (aOR, 0.89; P < .001), with similar results when restricting the analysis to patients with triple negative or hormone receptor-positive tumors.
After a median follow-up of 54 months, HER2-low disease was associated with a minor improvement in survival on multivariate analysis, at an adjusted hazard ratio for death of 0.98 (P < .001).
The greatest improvement in survival was seen in patients with stage III and IV triple-negative breast cancer, at HRs of 0.92 and 0.91, respectively, although the researchers noted that this represented only a 2% and 0.4% improvement in 5-year overall survival, respectively.
The study was supported by the Breast Cancer Research Foundation, the American Society of Clinical Oncology/Conquer Cancer Foundation, the Department of Defense, the National Institutes of Health/National Cancer Institute, Susan G. Komen, the Breast Cancer Research Foundation, and the University of Chicago Elwood V. Jensen Scholars Program. Dr. Howard reported no relevant financial relationships. Dr. Curigliano has relationships with Pfizer, Novartis, Lilly, Roche, Seattle Genetics, Celltrion, Veracyte, Daiichi Sankyo, AstraZeneca, Merck, Seagen, Exact Sciences, Gilead, Bristol-Myers Squibb, Scientific Affairs Group, and Ellipsis.
