Can Glucarpidase Help Reverse Methotrexate Kidney Damage?
TOPLINE:
METHODOLOGY:
- Researchers conducted a multicenter cohort study involving 708 adults with methotrexate-associated acute kidney injury from 28 cancer centers across the United States.
- Analysis utilized a sequential target trial emulation framework to compare outcomes between 209 patients who received glucarpidase within 4 days of methotrexate initiation and 499 patients who did not.
- The primary endpoint was kidney recovery at hospital discharge, defined as survival with serum creatinine < 1.5-fold baseline without dialysis dependence.
- Secondary endpoints included time-to-kidney recovery, neutropenia and transaminitis on day 7, and time-to-death.
TAKEAWAY:
- Glucarpidase administration was associated with adjusted odds ratio [aOR] of 2.70 (95% CI, 1.69-4.31) and adjusted hazard ratio [aHR] of 1.88 (95% CI, 1.18-3.33) for time-to-kidney recovery.
- Treatment with glucarpidase reduced the risk for grade ≥ 2 neutropenia (aOR, 0.50; 95% CI, 0.28-0.91) and grade ≥ 2 transaminitis (aOR, 0.31; 95% CI, 0.13-0.77) on day 7.
- Female patients showed greater benefit from glucarpidase treatment than male patients (P = .02 for interaction).
- No significant difference was observed in time-to-death between glucarpidase-treated and glucarpidase-untreated patients (aHR, 0.76; 95% CI, 0.49-1.18).
IN PRACTICE:
“These data suggest glucarpidase may improve both renal and extrarenal outcomes in patients with MTX-AKI [methotrexate-acute kidney injury],” the authors of the study wrote.
SOURCE:
This study was led by Shruti Gupta, MD, MPH, and David E. Leaf, MD, MMSc, Brigham and Women’s Hospital in Boston, Massachusetts. It was published online in Blood.
LIMITATIONS:
According to the authors, residual confounding cannot be excluded despite adjustment for multiple variables. While glucarpidase-treated patients had similar distributions of most baseline characteristics, they showed greater severity of illness, including more comorbidities, concomitant nephrotoxic medications, higher 24-hour methotrexate levels, and more severe acute kidney injury. This study was limited to patients treated at large, US-based academic centers, potentially affecting generalizability to smaller hospitals or countries where glucarpidase is unavailable.
DISCLOSURES:
This study was funded by BTG International. Gupta disclosed ties with BTG International, Dana-Farber Cancer Institute’s Wong Foundation, Janssen, AstraZeneca, and the National Institute of Diabetes and Digestive and Kidney Diseases (K23DK125672).

New Cancer Drugs: Do Patients Prefer Faster Access or Clinical Benefit?
When the Food and Drug Administration (FDA) grants cancer drugs accelerated approval, a key aim is to provide patients faster access to therapies that can benefit them.
The downside of a speedier approval timeline, however, is that it’s often not yet clear whether the new drugs will actually allow a patient to live longer or better. Information on overall survival and quality of life typically comes years later, after drugs undergo confirmatory trials, or sometimes not at all, if companies fail to conduct these trials.
During this waiting period, patients may be receiving a cancer drug that provides no real clinical benefit but comes with a host of toxicities.
In fact, the odds are about as good as a coin flip. For cancer drugs that have confirmatory trial data, more than half don’t ultimately provide an overall survival or quality of life benefit.
Inherent to the accelerated approval process is the assumption that patients are willing to accept this uncertainty in exchange for faster access.
But is that really the case?
The researchers asked about 870 adults with experience of cancer challenges — either their own cancer diagnosis or that of family or a close friend — whether they valued faster access or certainty that a drug really works.
In the study, participants imagined they had been diagnosed with cancer and could choose between two cancer drugs under investigation in clinical trials but with uncertain effectiveness, and a current standard treatment. Participants had to make a series of choices based on five scenarios.
The first two scenarios were based on the impact of the current standard treatment: A patient’s life expectancy on the standard treatment (6 months up to 3 years), and a patient’s physical health on the standard treatment (functional status restricted only during strenuous activities up to completely disabled).
The remaining three scenarios dealt with the two new drugs: The effect of the new drugs on a surrogate endpoint, progression-free survival (whether the drugs slowed tumor growth for an extra month or 5 additional months compared with the standard treatment), certainty that slowing tumor growth will improve survival (very low to high), and the wait time to access the drugs (immediately to as long as 2 years).
The researchers assessed the relative importance of survival benefit certainty vs wait time and how that balance shifted depending on the different scenarios.
Overall, the researchers found that, if there was no evidence linking the surrogate endpoint (progression-free survival) to overall survival, patients were willing to wait about 8 months for weak evidence of an overall survival benefit (ie, low certainty the drug will extend survival by 1-5 months), about 16 months for moderate certainty, and almost 22 months for high certainty.
Despite a willingness to wait for greater certainty, participants did value speed as well. Overall, respondents showed a strong preference against a 1-year delay in FDA approval time. People who were aged 55 years or more and were non-White individuals made less than $40,000 year as well as those with the lowest life expectancy on a current standard treatment were most sensitive to wait times while those with better functional status and longer life expectancies on a current treatment were less sensitive to longer wait times.
“Our results indicate that some patients (except those with the poorest prognoses) would find the additional time required to generate evidence on the survival benefit of new cancer drugs an acceptable tradeoff,” the study authors concluded.
Although people do place high value on timely access to new cancer drugs, especially if there are limited treatment options, many are willing to wait for greater certainty that a new drug provides an overall survival benefit, lead author Robin Forrest, MSc, with the Department of Health Policy, London School of Economics in England, said in an interview.
In the study, respondents also did not place significant value on whether the drug substantially slowed cancer growth. “In other words, substantial progression-free survival benefit of a drug did not compensate for lack of certainty about a drug’s benefit on survival in respondents’ drug choices,” the authors explained.
“In an effort to move quickly, we have accepted progression-free survival [as a surrogate endpoint],” Jyoti D. Patel, MD, oncologist with Northwestern Memorial Hospital, Chicago, Illinois, who wasn’t involved in the study. But a growing body of evidence indicates that progression-free survival is often a poor surrogate for overall survival. And what this study suggests is that “patients uniformly care about improvements in overall survival and the quality of that survival,” Patel said.
Bishal Gyawali, MD, PhD, was not surprised by the findings.
“I always thought this was the real-world scenario, but the problem is the voices of ordinary patients are not heard,” Gyawali, with Queen’s University, Kingston, Ontario, Canada, who also wasn’t involved in the study, said in an interview.
“What is heard is the loud noise of ‘we need access now, today, yesterday’ — ‘we don’t care if the drug doesn’t improve overall survival, we just need a drug, any drug’ — ‘we don’t care how much it costs, we need access today,’ ” Gyawali said. “Not saying this is wrong, but this is not the representation of all patients.”
However, the voices of patients who are more cautious and want evidence of benefit before accepting toxicities don’t make headlines, he added.
What this survey means from a policy perspective, said Gyawali, is that accelerated approvals that do not mandate survival endpoint in confirmatory trials are ignoring the need of many patients who prioritize certainty of benefit over speed of access.
The study was funded by the London School of Economics and Political Science Phelan United States Centre. Forrest had no relevant disclosures. Gyawali has received consulting fees from Vivio Health. Patel has various relationships with AbbVie, Anheart, AstraZeneca, Bristol-Myers Squibb, Guardant, Tempus, Sanofi, BluePrint, Takeda, and Gilead.

FROM THE LANCET ONCOLOGY
New Cancer Vaccines on the Horizon: Renewed Hope or Hype?
Vaccines for treating and preventing cancer have long been considered a holy grail in oncology.
But aside from a few notable exceptions — including the human papillomavirus (HPV) vaccine, which has dramatically reduced the incidence of HPV-related cancers, and a Bacillus Calmette-Guerin vaccine, which helps prevent early-stage bladder cancer recurrence — most have failed to deliver.
Following a string of disappointments over the past decade, recent advances in the immunotherapy space are bringing renewed hope for progress.
In an American Association for Cancer Research (AACR) series earlier in 2024, Catherine J. Wu, MD, predicted big strides for cancer vaccines, especially for personalized vaccines that target patient-specific neoantigens — the proteins that form on cancer cells — as well as vaccines that can treat diverse tumor types.
said Wu, the Lavine Family Chair of Preventative Cancer Therapies at Dana-Farber Cancer Institute and a professor of medicine at Harvard Medical School, both in Boston, Massachusetts.
A prime example is a personalized, messenger RNA (mRNA)–based vaccine designed to prevent melanoma recurrence. The mRNA-4157 vaccine encodes up to 34 different patient-specific neoantigens.
“This is one of the most exciting developments in modern cancer therapy,” said Lawrence Young, a virologist and professor of molecular oncology at the University of Warwick, Coventry, England, who commented on the investigational vaccine via the UK-based Science Media Centre.
Other promising options are on the horizon as well. In August, BioNTech announced a phase 1 global trial to study BNT116 — a vaccine to treat non–small cell lung cancer (NSCLC). BNT116, like mRNA-4157, targets specific antigens in the lung cancer cells.
“This technology is the next big phase of cancer treatment,” Siow Ming Lee, MD, a consultant medical oncologist at University College London Hospitals in England, which is leading the UK trial for the lung cancer and melanoma vaccines, told The Guardian. “We are now entering this very exciting new era of mRNA-based immunotherapy clinical trials to investigate the treatment of lung cancer.”
Still, these predictions have a familiar ring. While the prospects are exciting, delivering on them is another story. There are simply no guarantees these strategies will work as hoped.
Then: Where We Were
Cancer vaccine research began to ramp up in the 2000s, and in 2006, the first-generation HPV vaccine, Gardasil, was approved. Gardasil prevents infection from four strains of HPV that cause about 80% of cervical cancer cases.
In 2010, the Food and Drug Administration approved sipuleucel-T, the first therapeutic cancer vaccine, which improved overall survival in patients with hormone-refractory prostate cancer.
Researchers predicted this approval would “pave the way for developing innovative, next generation of vaccines with enhanced antitumor potency.”
In a 2015 AACR research forecast report, Drew Pardoll, MD, PhD, co-director of the Cancer Immunology and Hematopoiesis Program at Johns Hopkins University, Baltimore, Maryland, said that “we can expect to see encouraging results from studies using cancer vaccines.”
Despite the excitement surrounding cancer vaccines alongside a few successes, the next decade brought a longer string of late-phase disappointments.
In 2016, the phase 3 ACT IV trial of a therapeutic vaccine to treat glioblastoma multiforme (CDX-110) was terminated after it failed to demonstrate improved survival.
In 2017, a phase 3 trial of the therapeutic pancreatic cancer vaccine, GVAX, was stopped early for lack of efficacy.
That year, an attenuated Listeria monocytogenes vaccine to treat pancreatic cancer and mesothelioma also failed to come to fruition. In late 2017, concerns over listeria infections prompted Aduro Biotech to cancel its listeria-based cancer treatment program.
In 2018, a phase 3 trial of belagenpumatucel-L, a therapeutic NSCLC vaccine, failed to demonstrate a significant improvement in survival and further study was discontinued.
And in 2019, a vaccine targeting MAGE-A3, a cancer-testis antigen present in multiple tumor types, failed to meet endpoints for improved survival in a phase 3 trial, leading to discontinuation of the vaccine program.
But these disappointments and failures are normal parts of medical research and drug development and have allowed for incremental advances that helped fuel renewed interest and hope for cancer vaccines, when the timing was right, explained vaccine pioneer Larry W. Kwak, MD, PhD, deputy director of the Comprehensive Cancer Center at City of Hope, Duarte, California.
When it comes to vaccine progress, timing makes a difference. In 2011, Kwak and colleagues published promising phase 3 trial results on a personalized vaccine. The vaccine was a patient-specific tumor-derived antigen for patients with follicular lymphoma in their first remission following chemotherapy. Patients who received the vaccine demonstrated significantly longer disease-free survival.
But, at the time, personalized vaccines faced strong headwinds due, largely, to high costs, and commercial interest failed to materialize. “That’s been the major hurdle for a long time,” said Kwak.
Now, however, interest has returned alongside advances in technology and research. The big shift has been the emergence of lower-cost rapid-production mRNA and DNA platforms and a better understanding of how vaccines and potent immune stimulants, like checkpoint inhibitors, can work together to improve outcomes, he explained.
“The timing wasn’t right” back then, Kwak noted. “Now, it’s a different environment and a different time.”
A Turning Point?
Indeed, a decade later, cancer vaccine development appears to be headed in a more promising direction.
Among key cancer vaccines to watch is the mRNA-4157 vaccine, developed by Merck and Moderna, designed to prevent melanoma recurrence. In a recent phase 2 study, patients receiving the mRNA-4157 vaccine alongside pembrolizumab had nearly half the risk for melanoma recurrence or death at 3 years compared with those receiving pembrolizumab alone. Investigators are now evaluating the vaccine in a global phase 3 study in patients with high-risk, stage IIB to IV melanoma following surgery.
Another one to watch is the BNT116 NSCLC vaccine from BioNTech. This vaccine presents the immune system with NSCLC tumor markers to encourage the body to fight cancer cells expressing those markers while ignoring healthy cells. BioNTech also launched a global clinical trial for its vaccine this year.
Other notables include a pancreatic cancer mRNA vaccine, which has shown promising early results in a small trial of 16 patients. Of 16 patients who received the vaccine alongside chemotherapy and after surgery and immunotherapy, 8 responded. Of these eight, six remained recurrence free at 3 years. Investigators noted that the vaccine appeared to stimulate a durable T-cell response in patients who responded.
Kwak has also continued his work on lymphoma vaccines. In August, his team published promising first-in-human data on the use of personalized neoantigen vaccines as an early intervention in untreated patients with lymphoplasmacytic lymphoma. Among nine asymptomatic patients who received the vaccine, all achieved stable disease or better, with no dose-limiting toxicities. One patient had a minor response, and the median time to progression was greater than 72 months.
“The current setting is more for advanced disease,” Kwak explained. “It’s a tougher task, but combined with checkpoint blockade, it may be potent enough to work.”
Still, caution is important. Despite early promise, it’s too soon to tell which, if any, of these investigational vaccines will pan out in the long run. Like investigational drugs, cancer vaccines may show big promising initially but then fail in larger trials.
One key to success, according to Kwak, is to design trials so that even negative results will inform next steps.
But, he noted, failures in large clinical trials will “put a chilling effect on cancer vaccine research again.”
“That’s what keeps me up at night,” he said. “We know the science is fundamentally sound and we have seen glimpses over decades of research that cancer vaccines can work, so it’s really just a matter of tweaking things to optimize trial design.”
Companies tend to design trials to test if a vaccine works or not, without trying to understand why, he said.
“What we need to do is design those so that we can learn from negative results,” he said. That’s what he and his colleagues attempted to do in their recent trial. “We didn’t just look at clinical results; we’re interrogating the actual tumor environment to understand what worked and didn’t and how to tweak that for the next trial.”
Kwak and his colleagues found, for instance, that the vaccine had a greater effect on B cell–derived tumor cells than on cells of plasma origin, so “the most rational design for the next iteration is to combine the vaccine with agents that work directly against plasma cells,” he explained.
As for what’s next, Kwak said: “We’re just focused on trying to do good science and understand. We’ve seen glimpses of success. That’s where we are.”

But aside from a few notable exceptions — including the human papillomavirus (HPV) vaccine, which has dramatically reduced the incidence of HPV-related cancers, and a Bacillus Calmette-Guerin vaccine, which helps prevent early-stage bladder cancer recurrence — most have failed to deliver.
Following a string of disappointments over the past decade, recent advances in the immunotherapy space are bringing renewed hope for progress.
In an American Association for Cancer Research (AACR) series earlier in 2024, Catherine J. Wu, MD, predicted big strides for cancer vaccines, especially for personalized vaccines that target patient-specific neoantigens — the proteins that form on cancer cells — as well as vaccines that can treat diverse tumor types.
said Wu, the Lavine Family Chair of Preventative Cancer Therapies at Dana-Farber Cancer Institute and a professor of medicine at Harvard Medical School, both in Boston, Massachusetts.
A prime example is a personalized, messenger RNA (mRNA)–based vaccine designed to prevent melanoma recurrence. The mRNA-4157 vaccine encodes up to 34 different patient-specific neoantigens.
“This is one of the most exciting developments in modern cancer therapy,” said Lawrence Young, a virologist and professor of molecular oncology at the University of Warwick, Coventry, England, who commented on the investigational vaccine via the UK-based Science Media Centre.
Other promising options are on the horizon as well. In August, BioNTech announced a phase 1 global trial to study BNT116 — a vaccine to treat non–small cell lung cancer (NSCLC). BNT116, like mRNA-4157, targets specific antigens in the lung cancer cells.
“This technology is the next big phase of cancer treatment,” Siow Ming Lee, MD, a consultant medical oncologist at University College London Hospitals in England, which is leading the UK trial for the lung cancer and melanoma vaccines, told The Guardian. “We are now entering this very exciting new era of mRNA-based immunotherapy clinical trials to investigate the treatment of lung cancer.”
Still, these predictions have a familiar ring. While the prospects are exciting, delivering on them is another story. There are simply no guarantees these strategies will work as hoped.
Then: Where We Were
Cancer vaccine research began to ramp up in the 2000s, and in 2006, the first-generation HPV vaccine, Gardasil, was approved. Gardasil prevents infection from four strains of HPV that cause about 80% of cervical cancer cases.
In 2010, the Food and Drug Administration approved sipuleucel-T, the first therapeutic cancer vaccine, which improved overall survival in patients with hormone-refractory prostate cancer.
Researchers predicted this approval would “pave the way for developing innovative, next generation of vaccines with enhanced antitumor potency.”
In a 2015 AACR research forecast report, Drew Pardoll, MD, PhD, co-director of the Cancer Immunology and Hematopoiesis Program at Johns Hopkins University, Baltimore, Maryland, said that “we can expect to see encouraging results from studies using cancer vaccines.”
Despite the excitement surrounding cancer vaccines alongside a few successes, the next decade brought a longer string of late-phase disappointments.
In 2016, the phase 3 ACT IV trial of a therapeutic vaccine to treat glioblastoma multiforme (CDX-110) was terminated after it failed to demonstrate improved survival.
In 2017, a phase 3 trial of the therapeutic pancreatic cancer vaccine, GVAX, was stopped early for lack of efficacy.
That year, an attenuated Listeria monocytogenes vaccine to treat pancreatic cancer and mesothelioma also failed to come to fruition. In late 2017, concerns over listeria infections prompted Aduro Biotech to cancel its listeria-based cancer treatment program.
In 2018, a phase 3 trial of belagenpumatucel-L, a therapeutic NSCLC vaccine, failed to demonstrate a significant improvement in survival and further study was discontinued.
And in 2019, a vaccine targeting MAGE-A3, a cancer-testis antigen present in multiple tumor types, failed to meet endpoints for improved survival in a phase 3 trial, leading to discontinuation of the vaccine program.
But these disappointments and failures are normal parts of medical research and drug development and have allowed for incremental advances that helped fuel renewed interest and hope for cancer vaccines, when the timing was right, explained vaccine pioneer Larry W. Kwak, MD, PhD, deputy director of the Comprehensive Cancer Center at City of Hope, Duarte, California.
When it comes to vaccine progress, timing makes a difference. In 2011, Kwak and colleagues published promising phase 3 trial results on a personalized vaccine. The vaccine was a patient-specific tumor-derived antigen for patients with follicular lymphoma in their first remission following chemotherapy. Patients who received the vaccine demonstrated significantly longer disease-free survival.
But, at the time, personalized vaccines faced strong headwinds due, largely, to high costs, and commercial interest failed to materialize. “That’s been the major hurdle for a long time,” said Kwak.
Now, however, interest has returned alongside advances in technology and research. The big shift has been the emergence of lower-cost rapid-production mRNA and DNA platforms and a better understanding of how vaccines and potent immune stimulants, like checkpoint inhibitors, can work together to improve outcomes, he explained.
“The timing wasn’t right” back then, Kwak noted. “Now, it’s a different environment and a different time.”
A Turning Point?
Indeed, a decade later, cancer vaccine development appears to be headed in a more promising direction.
Among key cancer vaccines to watch is the mRNA-4157 vaccine, developed by Merck and Moderna, designed to prevent melanoma recurrence. In a recent phase 2 study, patients receiving the mRNA-4157 vaccine alongside pembrolizumab had nearly half the risk for melanoma recurrence or death at 3 years compared with those receiving pembrolizumab alone. Investigators are now evaluating the vaccine in a global phase 3 study in patients with high-risk, stage IIB to IV melanoma following surgery.
Another one to watch is the BNT116 NSCLC vaccine from BioNTech. This vaccine presents the immune system with NSCLC tumor markers to encourage the body to fight cancer cells expressing those markers while ignoring healthy cells. BioNTech also launched a global clinical trial for its vaccine this year.
Other notables include a pancreatic cancer mRNA vaccine, which has shown promising early results in a small trial of 16 patients. Of 16 patients who received the vaccine alongside chemotherapy and after surgery and immunotherapy, 8 responded. Of these eight, six remained recurrence free at 3 years. Investigators noted that the vaccine appeared to stimulate a durable T-cell response in patients who responded.
Kwak has also continued his work on lymphoma vaccines. In August, his team published promising first-in-human data on the use of personalized neoantigen vaccines as an early intervention in untreated patients with lymphoplasmacytic lymphoma. Among nine asymptomatic patients who received the vaccine, all achieved stable disease or better, with no dose-limiting toxicities. One patient had a minor response, and the median time to progression was greater than 72 months.
“The current setting is more for advanced disease,” Kwak explained. “It’s a tougher task, but combined with checkpoint blockade, it may be potent enough to work.”
Still, caution is important. Despite early promise, it’s too soon to tell which, if any, of these investigational vaccines will pan out in the long run. Like investigational drugs, cancer vaccines may show big promising initially but then fail in larger trials.
One key to success, according to Kwak, is to design trials so that even negative results will inform next steps.
But, he noted, failures in large clinical trials will “put a chilling effect on cancer vaccine research again.”
“That’s what keeps me up at night,” he said. “We know the science is fundamentally sound and we have seen glimpses over decades of research that cancer vaccines can work, so it’s really just a matter of tweaking things to optimize trial design.”
Companies tend to design trials to test if a vaccine works or not, without trying to understand why, he said.
“What we need to do is design those so that we can learn from negative results,” he said. That’s what he and his colleagues attempted to do in their recent trial. “We didn’t just look at clinical results; we’re interrogating the actual tumor environment to understand what worked and didn’t and how to tweak that for the next trial.”
Kwak and his colleagues found, for instance, that the vaccine had a greater effect on B cell–derived tumor cells than on cells of plasma origin, so “the most rational design for the next iteration is to combine the vaccine with agents that work directly against plasma cells,” he explained.
As for what’s next, Kwak said: “We’re just focused on trying to do good science and understand. We’ve seen glimpses of success. That’s where we are.”

Inside the Patient-Oncologist Bond: Why It’s Often So Strong
Rose Gerber was 39, mother to a third grader and a kindergartener, when the diagnosis came: Advanced HER2-positive breast cancer.
“On one of my first or second appointments, I took in a little picture of Alexander and Isabella,” Gerber said. Gerber showed her oncologist the picture and told her: “I’ll do anything. I just want to be there for them.”
That was 21 years ago. Today, her current cancer status is “no evidence of disease.”
Over the past 2 decades, Gerber has gotten to be there for her children. Her youngest is now a television producer and her oldest, a CPA.
In that time,
“I’ve seen multiple physicians over my 21 years, but my oncologist has always been the focal point, guiding me in the right direction,” Gerber said in an interview.
Over the years, Jaga guided Gerber through a range of treatment decisions, including a Herceptin clinical trial that the mom of two views as lifesaving. Jaga often took on the role of both doctor and therapist, even providing comfort in the smaller moments when Gerber would fret about her weight gain.
The oncologist-patient “bond is very, very, very special,” said Gerber, who now works as director of patient advocacy and education at the Community Oncology Alliance.
Gerber isn’t alone in calling out the depth of the oncologist-patient bond.
Over years, sometimes decades, patients and oncologists can experience a whole world together: The treatment successes, relapses, uncertainties, and tough calls. As a result, a deep therapeutic alliance often develops. And with each new hurdle or decision, that collaborative, human connection between doctor and patient continues to form new layers.
“It’s like a shared bonding experience over trauma, like strangers trapped on a subway and then we get out, and we’re now on the other side, celebrating together,” said Saad Khan, MD, an associate professor of medicine (oncology) at Stanford University in California.
Connecting Through Stress
Although studies exploring the oncologist-patient bond are limited, some research suggests that a strong therapeutic alliance between patients and oncologists not only provides a foundation for quality care but can also help improve patients’ quality of life, protect against suicidal ideation, and increase treatment adherence.
Because of how stressful and frightening a cancer diagnosis can be, creating “a trusting, uninterrupted, almost sacred environment for them” is paramount for Khan. “I have no doubt that the most important part of their treatment is that they find an oncologist in whom they have total confidence,” Khan wrote in a blog.
The stress that patients with cancer experience is well documented, but oncologists take on a lot themselves and can also experience intense stress (.
“I consider my patient’s battles to be my battles,” Khan wrote.
The stress can start with the daily schedule. Oncologists often have a high volume of patients and tend to spend more time with each individual than most.
According to a 2023 survey, oncologists see about 68 patients a week, on average, but some oncologists, like Khan, have many more. Khan typically sees 20-30 patients a day and continues to care for many over years.
The survey also found that oncologists tend to spend a lot of time with their patients. Compared with other physicians, oncologists are two times more likely to spend at least 25 minutes with each patient.
With this kind of patient volume and time, Khan said, “you’re going to be exhausted.”
What can compound the exhaustion are the occasions oncologists need to deliver bad news — this treatment isn’t working, your cancer has come roaring back and, perhaps the hardest, we have no therapeutic options left. The end-of-life conversations, in particular, can be heartbreaking, especially when a patient is young and not ready to stop trying.
“It can be hard for doctors to discuss the end of life,” Don Dizon, MD, director of the Pelvic Malignancies Program at Lifespan Cancer Institute and director of Medical Oncology at Rhode Island Hospital, Providence, wrote in a column in 2023. Instead, it can be tempting and is often easier to focus on the next treatment, “instilling hope that there’s more that can be done,” even if doing more will only do harm.
In the face of these challenging decisions, growing a personal connection with patients over time can help keep oncologists going.
“We’re not just chemotherapy salesmen,” Khan said in an interview. “We get to know their social support network, who’s going to be driving them [to and from appointments], where they go on vacation, their cat’s name, who their neighbors are.”
A ‘Special Relationship’
Ralph V. Boccia, MD, is often asked what he does.
The next question that often comes — “Why do I do what I do?” — is Boccia’s favorite.
“Someone needs to take these patients through their journey,” Boccia, the founder of The Center for Cancer and Blood Disorders, Bethesda, Maryland, typically responds. He also often notes that “it is a special relationship you develop with the patient and their families.”
Boccia thinks about one long-term patient who captures this bond.
Joan Pinson, 70, was diagnosed with multiple myeloma about 25 years ago, when patients’ average survival was about 4 years.
Over a quarter century, Pinson has pivoted to different treatments, amid multiple relapses and remissions. Throughout most of this cancer journey, Boccia has been her primary oncologist, performing a stem cell transplant in 2000 and steering her to six clinical trials.
Her last relapse was 2 years ago, and since then she has been doing well on oral chemotherapy.
“Every time I relapsed, by the next appointment, he’d say, ‘here is what we are going to do,’ ” Pinson recalled. “I never worried, I never panicked. I knew he would take care of me.”
Over the years, Pinson and Boccia have shared many personal moments, sometimes by accident. One special moment happened early on in Pinson’s cancer journey. During an appointment, Boccia had “one ear to the phone” as his wife was about to deliver their first baby, Pinson recalled.
Later, Pinson met that child as a young man working in Boccia’s lab. She has also met Boccia’s wife, a nurse, when she filled in one day in the chemotherapy room.
Boccia now also treats Pinson’s husband who has prostate cancer, and he ruled out cancer when Pinson’s son, now in his 40s, had some worrisome symptoms.
More than 2 decades ago, Pinson told Boccia her goal was to see her youngest child graduate from high school. Now, six grandsons later, she has lived far beyond that goal.
“He has kept me alive,” said Pinson.
The Dying Patient
Harsha Vyas, MD, FACP, remembers the first encounter his office had with a 29-year-old woman referred with a diagnosis of stage IV breast cancer.
After just 15 minutes in the waiting room, the woman announced she was leaving. Although office staff assured the woman that she was next, the patient walked out.
Several months later, Vyas was called for an inpatient consult. It was the same woman.
Her lungs were full of fluid, and she was struggling to breathe, said Vyas, president and CEO of the Cancer Center of Middle Georgia, Dublin, and assistant professor at Augusta University in Georgia.
The woman, a single mother, told Vyas about her three young kids at home and asked him, “Doc, do something, please help me,” he recalled.
“Absolutely,” Vyas told her. But he had to be brutally honest about her prognosis and firm that she needed to follow his instructions. “You have a breast cancer I cannot cure,” he said. “All I can do is control the disease.”
From that first day, until the day she died, she came to every appointment and followed the treatment plan Vyas laid out.
For about 2 years, she responded well to treatment. And as the time passed and the trust grew, she began to open up to him. She showed him pictures. She talked about her children and being a mother.
“I’ve got to get my kids in a better place. I’m going to be there for them,” he recalled her saying.
Vyas admired her resourcefulness. She held down a part-time job, working retail and at a local restaurant. She figured out childcare so she could get to her chemotherapy appointments every 3 weeks and manage the copays.
Several years later, when she knew she was approaching the end of her life, she asked Vyas a question that hit hard.
“Doc, I don’t want to die and my kids find me dead. What can we do about it?”
Vyas, who has three daughters, imagined how traumatic this would be for a child. She and Vyas made the shared decision to cease treatment and begin home hospice. When the end was approaching, a hospice worker took over, waiting for bodily functions to cease.
When news of a death comes, “I say a little prayer, it’s almost like a send-off for that soul. That helps me absorb the news ... and let it go.”
But when the bond grows strong over time, as with his patient with breast cancer, Vyas said, “a piece of her is still with me.”
Khan had no relevant disclosures. Boccia and Vyas had no disclosures.

“Doc, I don’t want to die and my kids find me dead. What can we do about it?”
Vyas, who has three daughters, imagined how traumatic this would be for a child. She and Vyas made the shared decision to cease treatment and begin home hospice. When the end was approaching, a hospice worker took over, waiting for bodily functions to cease.
When news of a death comes, “I say a little prayer, it’s almost like a send-off for that soul. That helps me absorb the news ... and let it go.”
But when the bond grows strong over time, as with his patient with breast cancer, Vyas said, “a piece of her is still with me.”

Rose Gerber was 39, mother to a third grader and a kindergartener, when the diagnosis came: Advanced HER2-positive breast cancer.
“On one of my first or second appointments, I took in a little picture of Alexander and Isabella,” Gerber said. Gerber showed her oncologist the picture and told her: “I’ll do anything. I just want to be there for them.”
That was 21 years ago. Today, her current cancer status is “no evidence of disease.”
Over the past 2 decades, Gerber has gotten to be there for her children. Her youngest is now a television producer and her oldest, a CPA.
In that time,
“I’ve seen multiple physicians over my 21 years, but my oncologist has always been the focal point, guiding me in the right direction,” Gerber said in an interview.
Over the years, Jaga guided Gerber through a range of treatment decisions, including a Herceptin clinical trial that the mom of two views as lifesaving. Jaga often took on the role of both doctor and therapist, even providing comfort in the smaller moments when Gerber would fret about her weight gain.
The oncologist-patient “bond is very, very, very special,” said Gerber, who now works as director of patient advocacy and education at the Community Oncology Alliance.
Gerber isn’t alone in calling out the depth of the oncologist-patient bond.
Over years, sometimes decades, patients and oncologists can experience a whole world together: The treatment successes, relapses, uncertainties, and tough calls. As a result, a deep therapeutic alliance often develops. And with each new hurdle or decision, that collaborative, human connection between doctor and patient continues to form new layers.
“It’s like a shared bonding experience over trauma, like strangers trapped on a subway and then we get out, and we’re now on the other side, celebrating together,” said Saad Khan, MD, an associate professor of medicine (oncology) at Stanford University in California.
Connecting Through Stress
Although studies exploring the oncologist-patient bond are limited, some research suggests that a strong therapeutic alliance between patients and oncologists not only provides a foundation for quality care but can also help improve patients’ quality of life, protect against suicidal ideation, and increase treatment adherence.
Because of how stressful and frightening a cancer diagnosis can be, creating “a trusting, uninterrupted, almost sacred environment for them” is paramount for Khan. “I have no doubt that the most important part of their treatment is that they find an oncologist in whom they have total confidence,” Khan wrote in a blog.
The stress that patients with cancer experience is well documented, but oncologists take on a lot themselves and can also experience intense stress (.
“I consider my patient’s battles to be my battles,” Khan wrote.
The stress can start with the daily schedule. Oncologists often have a high volume of patients and tend to spend more time with each individual than most.
According to a 2023 survey, oncologists see about 68 patients a week, on average, but some oncologists, like Khan, have many more. Khan typically sees 20-30 patients a day and continues to care for many over years.
The survey also found that oncologists tend to spend a lot of time with their patients. Compared with other physicians, oncologists are two times more likely to spend at least 25 minutes with each patient.
With this kind of patient volume and time, Khan said, “you’re going to be exhausted.”
What can compound the exhaustion are the occasions oncologists need to deliver bad news — this treatment isn’t working, your cancer has come roaring back and, perhaps the hardest, we have no therapeutic options left. The end-of-life conversations, in particular, can be heartbreaking, especially when a patient is young and not ready to stop trying.
“It can be hard for doctors to discuss the end of life,” Don Dizon, MD, director of the Pelvic Malignancies Program at Lifespan Cancer Institute and director of Medical Oncology at Rhode Island Hospital, Providence, wrote in a column in 2023. Instead, it can be tempting and is often easier to focus on the next treatment, “instilling hope that there’s more that can be done,” even if doing more will only do harm.
In the face of these challenging decisions, growing a personal connection with patients over time can help keep oncologists going.
“We’re not just chemotherapy salesmen,” Khan said in an interview. “We get to know their social support network, who’s going to be driving them [to and from appointments], where they go on vacation, their cat’s name, who their neighbors are.”
A ‘Special Relationship’
Ralph V. Boccia, MD, is often asked what he does.
The next question that often comes — “Why do I do what I do?” — is Boccia’s favorite.
“Someone needs to take these patients through their journey,” Boccia, the founder of The Center for Cancer and Blood Disorders, Bethesda, Maryland, typically responds. He also often notes that “it is a special relationship you develop with the patient and their families.”
Boccia thinks about one long-term patient who captures this bond.
Joan Pinson, 70, was diagnosed with multiple myeloma about 25 years ago, when patients’ average survival was about 4 years.
Over a quarter century, Pinson has pivoted to different treatments, amid multiple relapses and remissions. Throughout most of this cancer journey, Boccia has been her primary oncologist, performing a stem cell transplant in 2000 and steering her to six clinical trials.
Her last relapse was 2 years ago, and since then she has been doing well on oral chemotherapy.
“Every time I relapsed, by the next appointment, he’d say, ‘here is what we are going to do,’ ” Pinson recalled. “I never worried, I never panicked. I knew he would take care of me.”
Over the years, Pinson and Boccia have shared many personal moments, sometimes by accident. One special moment happened early on in Pinson’s cancer journey. During an appointment, Boccia had “one ear to the phone” as his wife was about to deliver their first baby, Pinson recalled.
Later, Pinson met that child as a young man working in Boccia’s lab. She has also met Boccia’s wife, a nurse, when she filled in one day in the chemotherapy room.
Boccia now also treats Pinson’s husband who has prostate cancer, and he ruled out cancer when Pinson’s son, now in his 40s, had some worrisome symptoms.
More than 2 decades ago, Pinson told Boccia her goal was to see her youngest child graduate from high school. Now, six grandsons later, she has lived far beyond that goal.
“He has kept me alive,” said Pinson.
The Dying Patient
Harsha Vyas, MD, FACP, remembers the first encounter his office had with a 29-year-old woman referred with a diagnosis of stage IV breast cancer.
After just 15 minutes in the waiting room, the woman announced she was leaving. Although office staff assured the woman that she was next, the patient walked out.
Several months later, Vyas was called for an inpatient consult. It was the same woman.
Her lungs were full of fluid, and she was struggling to breathe, said Vyas, president and CEO of the Cancer Center of Middle Georgia, Dublin, and assistant professor at Augusta University in Georgia.
The woman, a single mother, told Vyas about her three young kids at home and asked him, “Doc, do something, please help me,” he recalled.
“Absolutely,” Vyas told her. But he had to be brutally honest about her prognosis and firm that she needed to follow his instructions. “You have a breast cancer I cannot cure,” he said. “All I can do is control the disease.”
From that first day, until the day she died, she came to every appointment and followed the treatment plan Vyas laid out.
For about 2 years, she responded well to treatment. And as the time passed and the trust grew, she began to open up to him. She showed him pictures. She talked about her children and being a mother.
“I’ve got to get my kids in a better place. I’m going to be there for them,” he recalled her saying.
Vyas admired her resourcefulness. She held down a part-time job, working retail and at a local restaurant. She figured out childcare so she could get to her chemotherapy appointments every 3 weeks and manage the copays.
Several years later, when she knew she was approaching the end of her life, she asked Vyas a question that hit hard.
“Doc, I don’t want to die and my kids find me dead. What can we do about it?”
Vyas, who has three daughters, imagined how traumatic this would be for a child. She and Vyas made the shared decision to cease treatment and begin home hospice. When the end was approaching, a hospice worker took over, waiting for bodily functions to cease.

For Radiation ‘Downwinders,’ Cancer Compensation Is On Hold
As of 2022, more than 40,000 patients with cancer successfully applied for $2.6 billion in compensation. Recipients included “downwinders” who were eligible for $50,000 each if they lived in certain areas of Nevada, Utah, and Arizona during specified nuclear testing periods and developed a covered form of cancer.
In June 2024, however, the Radiation Exposure Compensation Program expired amid infighting among Republicans in Congress over whether to expand it. For now, no one can make a claim, even though many downwinders are still alive and continue to be diagnosed with covered cancers decades after they were exposed in the 1940s, 1950s, and 1960s.
There’s a glimmer of good news. The federal government continues to support free medical screenings for eligible people, including certain downwinders and uranium workers. Meanwhile, there are still important roles for clinicians across the country to play as politicians figure out what — if anything — to do next regarding those exposed to radiation.
“We are still here. We can still screen people,” Zachary Davis, program director for the Radiation Exposure Screening and Education Program, The University of New Mexico, in Albuquerque, New Mexico, said in an interview.
Still-Unfolding Legacy of Radiation Exposure
No one knew just how far radiation would spread when the first nuclear bomb was tested in New Mexico in July 1945. Would it cover the state? The entire Southwest? The whole nation?
It also wasn’t clear how radiation would affect people’s health. “There was an awareness that some cancers were caused by radiation, but there wasn’t a cohesive understanding of what the problem was,” Joseph Shonka, PhD, a health physicist who studies radiation exposure and has worked for decades in nuclear engineering, said in an interview.
Now, nearly eight decades later, scientists are still figuring out the full extent of radioactive fallout from nuclear testing. Just last year, a study suggested that radiation from 94 nuclear weapon tests in the Southwest from 1945 to 1962 reached 46 states along with Canada and Mexico.
Activists believe the tests triggered untold number of cancer cases in residents who were exposed in downwind areas:
“My brother died of stomach cancer; my mom died of bone cancer. One of my sisters is surviving brain tumors, and the other one is surviving thyroid cancer,” one New Mexico man recently told ABC-TV’s “Nightline.”
In Idaho, a downwinder advocate told Idaho Capital Sun that everyone who attended a reception for her newly married parents in 1952 — just weeks after a nuclear test — developed cancer or “weird medical complications.” That included her parents, who both had cancer. Her two older brothers, born in 1953 and 1955, also developed cancer, and she’s tracked many other cases in the small town of Emmett.
In Utah, another downwinder advocate told Utah News Dispatch that cancer was common in Salt Lake City neighborhood, where she grew up, which was exposed to fallout. She developed thyroid cancer, her younger sister developed stomach cancer, and an older sister died of lupus, which is connected to radiation exposure. But Salt Lake City isn’t in one of the regions of Utah covered by the federal compensation program, so the advocate can’t get a $50,000 payment.
Downwinders who lived in New Mexico, Idaho, and the Salt Lake City area of Utah are not covered by the federal compensation program. That means none of these people or their descendants are eligible for payments — yet.
Decades After Nuclear Testing, the Government Responds
In 1990, Congress passed the Radiation Exposure Compensation Act, which allowed compensation to people with cancer at several levels. It was later expanded. Downwinders — including those who’ve moved elsewhere over the years — were eligible for $50,000. Onsite participants in nuclear testing could get $75,000. Uranium miners, millers, and ore transporters in 11 states west of the Mississippi River could get $100,000.
Among downwinders, eligible cancers included blood cancers (leukemias with the exception of chronic lymphocytic leukemia, multiple myeloma, and non-Hodgkin’s lymphomas) and a long list of solid organ cancers such as thyroid, breast, stomach, brain, lung, colon, and liver cancers.
“When it comes to blood-related cancers, we do see leukemias, lymphomas, and multiple myeloma, but these cancers were more likely to occur sooner after fallout exposure,” said Laura Shaw, MD, principal investigator who oversees the radiation exposure screening program at the University of Nevada, Las Vegas. “At this point, we see more pancreatic, thyroid, lung, stomach, bladder, and breast cancer.”
The compensation program had major limitations, critics said. “It left out a lot of communities that were exposed,” said Lilly Adams, senior outreach coordinator with the Union of Concerned Scientists (UCS), which supports expanding the program. A national nonprofit organization, UCS was founded more than 50 years ago by scientists and students at the Massachusetts Institute of Technology.
“You have this pretty small amount of one-time compensation, and that’s it,” Adams said in an interview. “You can’t get reimbursed for medical costs or lost wages.” Still, “as flawed as the program is, it’s really valuable for the people who are eligible,” she noted.
Now Congress Is Divided on Next Steps
Some lawmakers have recognized the need to do more for those who developed cancer that’s potentially linked to radiation exposure. As the June 2024 expiration of the Radiation Exposure Compensation Act loomed, Democrats and Republicans in Congress worked together to extend and expand the program.
They introduced a bill for higher compensation — $100,000 per person — and the widening of covered downwinder areas to all of Arizona, Nevada, and Utah (which had only been partially covered), along with all of Colorado, Idaho, New Mexico, Montana, and Guam. Under the legislation, the program also would expand to cover some uranium workers who were on the job after 1971 and residents exposed to nuclear waste in Kentucky, Missouri, and Tennessee.
In March, the new legislation easily passed the US Senate by a vote of 69-30, with support from both political parties — but the Republican-led House hasn’t taken it up. As a result, the Radiation Exposure Compensation Act expired in June, and no one can submit new applications for compensation.
A spokesman for House Speaker Mike Johnson told Missouri Independent “unfortunately, the current Senate bill is estimated to cost $50-$60 billion in new mandatory spending with no offsets and was supported by only 20 of 49 Republicans in the Senate.”
Adams rejected these arguments. “The government spends literally trillions of dollars on our nuclear weapons. Whether or not you support that spending, the human cost of building those weapons should be factored in,” she said. She added that she hopes the House will act by the end of the year to pass the bill, but that’s uncertain.
As Compensation Is On Hold, Medical Screening Continues
A major benefit is still available for downwinders and uranium workers: Free medical screening and referrals for medical treatment. The Radiation Exposure Screening and Education Program’s funding has not been affected by the congressional impasse, so screenings are continuing for eligible people exposed to radiation.
Radiation exposure clinics offer screening in Arizona, Colorado, Nevada, New Mexico, and Utah, and health providers can get funding to offer screening in other affected states.
In Nevada, “we hold screening clinics throughout the state: Caliente, Ely, and Winnemucca. Also, in Reno and Las Vegas, which are not in designated downwind areas, but many downwinders have migrated there,” said Shaw in an interview. Among downwinders, “our youngest patients are in their 60s and range up to a few in their 90s,” she said.
Patients fill out questionnaires that ask about their medical problems, family history, and medications. “Ely patients in particular seem to have extensive family histories of cancer, and this may be due to their location directly downwind of the Nevada Test Site,” Shaw said. (Ely is a remote town in central eastern Nevada near the Utah border.)
The screenings cover both cancer and noncancer conditions. Shaw said clinicians often diagnose problems other than the covered cancers — new cases of atrial fibrillation, diabetes, and hypertension. “We see a ton of prostate and skin cancer” but don’t make patients eligible for the compensation program because they’re not covered, she said.
Even as compensation is on hold, doctors can get the word out that screenings are still available, Shaw said. “We continue to get contacted by individuals who in these communities who have never heard of this program, even though we’ve been holding clinics since 2005,” Shaw said. “Despite outreach activities and advertising through newspapers and radio, we find the most successful method of reaching these patients is through word of mouth — either from other patients or their doctors. That is why we feel it is so important to reach other physicians as well.”
Affected Patients Don’t Just Live in the West
On the outreach front, clinicians in states outside of the western US region can be helpful, too. Shaw urged oncologists nationwide to ask older patients where they lived in the 1950s and 1960s. “Did they live in Nevada, Arizona, Utah, and other Western states that are downwind? They may qualify for needed services and future compensation.”
With regard to compensation, she noted that applicants need to prove that they lived in affected areas many decades ago. And, of course, they must prove that they’ve had cancer. Locating residency records “has often been an enormous challenge.” Old utility bills, pay stubs, and high school annuals can be helpful, “but these records tend to disappear. People and their families throw stuff away.”
Even proving a cancer diagnosis can be a challenge because records can be missing. In Nevada, the law says clinicians only need to keep medical records for 5 years, Shaw said. “Imaging and pathology reports are destroyed. Patients that have been diagnosed with cancer can’t prove it.”
Shaw said she hopes oncologists will offer these messages to patients: “Be an advocate for your own health and keep copies of your own records. Discuss your diagnosis with your family and contact a cancer registry if you are diagnosed with cancer.”

“You have this pretty small amount of one-time compensation, and that’s it,” Adams said in an interview. “You can’t get reimbursed for medical costs or lost wages.” Still, “as flawed as the program is, it’s really valuable for the people who are eligible,” she noted.
Now Congress Is Divided on Next Steps
Some lawmakers have recognized the need to do more for those who developed cancer that’s potentially linked to radiation exposure. As the June 2024 expiration of the Radiation Exposure Compensation Act loomed, Democrats and Republicans in Congress worked together to extend and expand the program.
They introduced a bill for higher compensation — $100,000 per person — and the widening of covered downwinder areas to all of Arizona, Nevada, and Utah (which had only been partially covered), along with all of Colorado, Idaho, New Mexico, Montana, and Guam. Under the legislation, the program also would expand to cover some uranium workers who were on the job after 1971 and residents exposed to nuclear waste in Kentucky, Missouri, and Tennessee.
In March, the new legislation easily passed the US Senate by a vote of 69-30, with support from both political parties — but the Republican-led House hasn’t taken it up. As a result, the Radiation Exposure Compensation Act expired in June, and no one can submit new applications for compensation.
A spokesman for House Speaker Mike Johnson told Missouri Independent “unfortunately, the current Senate bill is estimated to cost $50-$60 billion in new mandatory spending with no offsets and was supported by only 20 of 49 Republicans in the Senate.”
Adams rejected these arguments. “The government spends literally trillions of dollars on our nuclear weapons. Whether or not you support that spending, the human cost of building those weapons should be factored in,” she said. She added that she hopes the House will act by the end of the year to pass the bill, but that’s uncertain.
As Compensation Is On Hold, Medical Screening Continues
A major benefit is still available for downwinders and uranium workers: Free medical screening and referrals for medical treatment. The Radiation Exposure Screening and Education Program’s funding has not been affected by the congressional impasse, so screenings are continuing for eligible people exposed to radiation.
Radiation exposure clinics offer screening in Arizona, Colorado, Nevada, New Mexico, and Utah, and health providers can get funding to offer screening in other affected states.
In Nevada, “we hold screening clinics throughout the state: Caliente, Ely, and Winnemucca. Also, in Reno and Las Vegas, which are not in designated downwind areas, but many downwinders have migrated there,” said Shaw in an interview. Among downwinders, “our youngest patients are in their 60s and range up to a few in their 90s,” she said.
Patients fill out questionnaires that ask about their medical problems, family history, and medications. “Ely patients in particular seem to have extensive family histories of cancer, and this may be due to their location directly downwind of the Nevada Test Site,” Shaw said. (Ely is a remote town in central eastern Nevada near the Utah border.)
The screenings cover both cancer and noncancer conditions. Shaw said clinicians often diagnose problems other than the covered cancers — new cases of atrial fibrillation, diabetes, and hypertension. “We see a ton of prostate and skin cancer” but don’t make patients eligible for the compensation program because they’re not covered, she said.
Even as compensation is on hold, doctors can get the word out that screenings are still available, Shaw said. “We continue to get contacted by individuals who in these communities who have never heard of this program, even though we’ve been holding clinics since 2005,” Shaw said. “Despite outreach activities and advertising through newspapers and radio, we find the most successful method of reaching these patients is through word of mouth — either from other patients or their doctors. That is why we feel it is so important to reach other physicians as well.”
Affected Patients Don’t Just Live in the West
On the outreach front, clinicians in states outside of the western US region can be helpful, too. Shaw urged oncologists nationwide to ask older patients where they lived in the 1950s and 1960s. “Did they live in Nevada, Arizona, Utah, and other Western states that are downwind? They may qualify for needed services and future compensation.”
With regard to compensation, she noted that applicants need to prove that they lived in affected areas many decades ago. And, of course, they must prove that they’ve had cancer. Locating residency records “has often been an enormous challenge.” Old utility bills, pay stubs, and high school annuals can be helpful, “but these records tend to disappear. People and their families throw stuff away.”
Even proving a cancer diagnosis can be a challenge because records can be missing. In Nevada, the law says clinicians only need to keep medical records for 5 years, Shaw said. “Imaging and pathology reports are destroyed. Patients that have been diagnosed with cancer can’t prove it.”
Shaw said she hopes oncologists will offer these messages to patients: “Be an advocate for your own health and keep copies of your own records. Discuss your diagnosis with your family and contact a cancer registry if you are diagnosed with cancer.”

How to Treat Cancer While Preserving Fertility
Thanks to the continuously improving treatment options for cancer, the number of cancer survivors is increasing, and a large proportion of survivors is confronted with the long-term effects of cancer treatment. Especially for young patients, the question of the impact of therapy on fertility arises.
Dose adjustment or modification of the treatment regimen can achieve a lot. But experts at the congress of the European Society for Medical Oncology (ESMO) 2024 noted that knowledge about newer treatment options like immunotherapies is still insufficient.
Therapy Selection
The question of preserving fertility must be considered when deciding on the appropriate treatment, said Matteo Lambertini, MD, PhD, medical oncology consultant at the University of Genoa in Genoa, Italy. “Preserving fertility is also an aim of cancer therapy,” he said.
Lambertini, who is also a member of the ESMO Guideline Group on fertility preservation in cancer patients, referred to the 2020 ESMO guidelines, which list the gonadotoxicity of a substance depending on the treatment regimen and the patient’s age.
Isabelle Demeestere, MD, PhD, director of the research lab for human reproduction at the Erasmus Hospital of the Free University of Brussels in Brussels, Belgium, pointed out the limitations of general guidelines. “Therapies change over time, and a classification must be updated regularly.”
Knowledge gaps related to well-known therapies and many novel options persist. “For many FDA-approved medications, there are either no fertility data or only preclinical data available,” she added.
Chemotherapies and Immunotherapies
Chemotherapies with alkylating or platinum-containing substances are known for their effects on oocytes, follicle maturation, and spermatogenesis, said Demeestere.
Chemotherapy is gonadotoxic and leads to a temporary decrease in sperm quality or temporary azoospermia in men.
These effects, however, can lead to permanent azoospermia and endocrine disorders, depending on the dose, duration, or combination with radiation, said Demeestere.
Cryopreservation of sperm should always be performed before starting treatment. For high-risk patients who are prepubertal, samples of testicular tissue are taken.
In women, chemotherapy affects primordial follicles and follicle maturation through DNA damage. This process results in severe or temporary amenorrhea, a temporary or permanent decrease in egg reserve, and ultimately premature egg insufficiency.
Novel immunotherapies also influence fertility, presumably through interactions of the immune system with the reproductive organs. But insufficient data are available, according to Lambertini, who emphasized that “these data are urgently needed, especially for young patients with cancer.”
In a mouse model, immune checkpoint inhibitors affected ovarian function, and the inflammatory reaction in humans can affect fertility. No long-term data are available for women yet, however, explained Demeestere. The effects of other therapeutics such as PARP, CDK4/6, or tyrosine kinase inhibitors, as well as monoclonal antibodies like trastuzumab, are only seen sporadically.
In the PENELOPE-B phase 3 study, the CDK4/6 inhibitor palbociclib did not affect ovarian function, even though the cyclin-dependent kinases play an important role in mitotic arrest, said Demeestere.
Adjusting the Regimen
In a PET-guided approach, Demeestere’s research team investigated the effects of dose reduction or adjustment of the treatment regimen of procarbazine and cyclophosphamide on the fertility of patients younger than 45 years with advanced Hodgkin lymphoma.
By regularly controlling tumor growth with PET, the treatment could be adjusted so that the effect on egg reserve or spermatogenesis was significantly reduced and loss of fertility could be prevented.
During the 5-year follow-up period, the ovarian function of participating women was assessed by the serum concentration of follicle-stimulating hormone (FSH), estradiol, and anti-Müllerian hormone (AMH) to evaluate egg reserve. In men, testicular function was assessed at the beginning of the study. At the end of treatment, sperm analysis and FSH and testosterone levels were checked.
Demeestere and colleagues demonstrated that dose reduction or altering the treatment regimen for patients who responded early to treatment (determined by PET-guided monitoring) reduced the risk for gonadotoxicity from 46% to 14.5%. That is, the risk was reduced by more than half.
FSH and AMH correlated with the patient’s age and the dose of the alkylating agent. In men, sperm parameters recovered after dose or agent adjustment compared with the unchanged treatment regimen.
Newer results from the PHERGain study in women with early human epidermal growth factor receptor 2–positive breast cancer also provided hope, according to Demeestere. Under PET-guided control, chemotherapy could be reduced.
More Data Needed
The new treatment options pose a challenge to preserving fertility during cancer treatment, said Demeestere.
For new targeted therapies, uniform recommendations cannot be issued because of the lack of data and varying treatment durations. Still, the new therapies are safer than chemotherapy.
The need to collect data on fertility and long-term effects in cancer survivors in clinical studies is also reflected in the literature, according to Demeestere. “There are more review articles on this topic than clinical studies.”

Popular Weight Loss Drugs Now for Patients With Cancer?
Demand for new weight loss drugs has surged over the past few years.
Led by the antiobesity drugs semaglutide (Wegovy) and tirzepatide (Zepbound), these popular medications — more commonly known as glucagon-like peptide 1 (GLP-1) agonists — have become game changers for shedding excess pounds.
Aside from obesity indications, both drugs have been approved to treat type 2 diabetes under different brand names and have a growing list of other potential benefits, such as reducing inflammation and depression.
While there’s limited data to support the use of GLP-1 agonists for weight loss in cancer, some oncologists have begun carefully integrating the antiobesity agents into care and studying their effects in this patient population.
The reason: Research suggests that obesity can reduce the effectiveness of cancer therapies, especially in patients with breast cancer, and can increase the risk for treatment-related side effects.
The idea is that managing patients’ weight will improve their cancer outcomes, explained Lajos Pusztai, MD, PhD, a breast cancer specialist and professor of medicine at Yale School of Medicine in New Haven, Connecticut.
Although Dr. Pusztai and his oncology peers at Yale don’t yet use GPL-1 agonists, Neil Iyengar, MD, and colleagues have begun doing so to help some patients with breast cancer manage their weight. Dr. Iyengar estimates that a few hundred — almost 40% — of his patients are on the antiobesity drugs.
“For a patient who has really tried to reduce their weight and who is in the obese range, that’s where I think the use of these medications can be considered,” said Dr. Iyengar, a breast cancer oncologist at Memorial Sloan Kettering Cancer Center in New York City.
Why GLP-1s in Cancer?
GLP-1 is a hormone that the small intestine releases after eating. GLP-1 agonists work by mimicking GLP-1 to trigger the release of insulin and reduce the production of glucagon — two processes that help regulate blood sugar.
These agents, such as Wegovy (or Ozempic when prescribed for diabetes), also slow gastric emptying and can make people feel fuller longer.
Zebound (or Mounjaro for type 2 diabetes) is considered a dual GLP-1 and glucose-dependent insulinotropic polypeptide agonist, which may enhance its weight loss benefits.
In practice, however, these drugs can increase nausea and vomiting from chemotherapy, so Dr. Iyengar typically has patients use them afterwards, during maintenance treatment.
Oncologists don’t prescribe the drugs themselves but instead refer patients to endocrinologists or weight management centers that then write the prescriptions. Taking these drugs involves weekly subcutaneous injections patients can administer themselves.
Endocrinologist Emily Gallagher, MD, PhD, of Mount Sinai Hospital in New York City, estimates she has prescribed the antiobesity drugs to a few hundred patients with cancer and, like Dr. Iyengar, uses the drugs during maintenance treatment with hormone therapy for breast cancer. She also has used these agents in patients with prostate and endometrial cancers and has found the drugs can help counter steroid weight gain in multiple myeloma.
But, to date, the evidence for using GPL-1 agonists in cancer remains limited and the practice has not yet become widespread.
Research largely comes down to a few small retrospective studies in patients with breast cancer receiving aromatase inhibitors. Although no safety issues have emerged so far, these initial reports suggest that the drugs lead to significantly less weight loss in patients with cancer compared to the general population.
Dr. Iyengar led one recent study, presented at the 2024 annual meeting of the American Society of Clinical Oncology, in which he and his team assessed outcomes in 75 women with breast cancer who received a GLP-1 agonist. Almost 80% of patients had diabetes, and 60% received hormone therapy, most commonly an aromatase inhibitor. Patients’ median body mass index (BMI) at baseline was 34 kg/m2 (range, 23-50 kg/m2).
From baseline, patients lost 6.2 kg, on average, or about 5% of their total body weight, 12 months after initiating GLP-1 therapy.
In contrast, phase 3 trials show much higher mean weight loss — about two times — in patients without cancer.
Another recent study also reported modest weight loss results in patients with breast cancer undergoing endocrine therapy. The researchers reported that, at 12 months, Wegovy led to 4.34% reduction in BMI, compared with a 14% change reported in the general population. Zebound, however, was associated with a 2.31% BMI increase overall — though some patients did experience a decrease — compared with a 15% reduction in the general population.
“These findings indicate a substantially reduced weight loss efficacy in breast cancer patients on endocrine therapy compared to the general population,” the authors concluded.
It’s unclear why the drugs appear to not work as well in patients with cancer. It’s possible that hormone therapy or metabolic changes interfere with their effectiveness, given that some cancer therapies lead to weight gain. Steroids and hormone therapies, for instance, often increase appetite, and some treatments can slow patients’ metabolism or lead to fatigue, which can make it harder to exercise.
Patients with cancer may need a higher dose of GLP-1 agonists to achieve similar weight loss to the general population, Dr. Iyengar noted.
However, Dr. Gallagher said, in her own experience, she hasn’t found the drugs to be less effective in patients with cancer, especially the newer agents, like Wegovy and Zepbound.
As for safety, Wegovy and Zepbound both carry a black box warning for thyroid C-cell tumors, including medullary thyroid carcinoma. (Recent research, however, has found that GLP-1 agonists do not increase thyroid cancer risk).
These antiobesity agents are also contraindicated in patients with a personal or family history of medullary thyroid carcinoma and in patients who have multiple endocrine neoplasia syndrome type 2, which is associated with medullary thyroid carcinoma.
Dr. Gallagher hasn’t seen any secondary tumors — thyroid or otherwise — in her patients with cancer, but she follows the labeling contraindications. Dr. Iyengar also noted that more recent and larger data sets have shown no impact on this risk, which may not actually exist, he said
Dr. Gallagher remains cautious about using GPL-1 agonists in patients who have had bariatric surgery because these agents can compound the slower gastric emptying and intestinal transit from surgery, potentially leading to gastrointestinal obstructions.
Looking ahead, GPL-1 manufacturers are interested in adding cancer indications to the drug labeling. Both Dr. Iyengar and Dr. Gallagher said their institutions are in talks with companies to participate in large, multicenter, global phase 3 trials.
Dr. Iyengar welcomes the efforts, not only to test the effectiveness of GPL-1 agonists in oncology but also to “nail down” their safety in cancer.
“I don’t think that there’s mechanistically anything that’s particularly worrisome,” and current observations suggest that these drugs are likely to be safe, Dr. Iyengar said. Even so, “GLP-1 agonists do a lot of things that we don’t fully understand yet.”
The bigger challenge, Dr. Iyengar noted, is that companies will have to show a sizable benefit to using these drugs in patients with cancer to get the Food and Drug Administration’s approval. And to move the needle on cancer-specific outcomes, these antiobesity drugs will need to demonstrate significant, durable weight loss in patients with cancer.
But if these drugs can do that, “I think it’s going to be one of the biggest advances in medicine and oncology given the obesity and cancer epidemic,” Dr. Iyengar said.
Dr. Iyengar has adviser and/or researcher ties with companies that make or are developing GPL-1 agonists, including AstraZeneca, Novartis, Gilead, and Pfizer. Dr. Gallagher is a consultant for Novartis, Flare Therapeutics, Reactive Biosciences, and Seagen.

But if these drugs can do that, “I think it’s going to be one of the biggest advances in medicine and oncology given the obesity and cancer epidemic,” Dr. Iyengar said.
Dr. Iyengar has adviser and/or researcher ties with companies that make or are developing GPL-1 agonists, including AstraZeneca, Novartis, Gilead, and Pfizer. Dr. Gallagher is a consultant for Novartis, Flare Therapeutics, Reactive Biosciences, and Seagen.

Demand for new weight loss drugs has surged over the past few years.
Led by the antiobesity drugs semaglutide (Wegovy) and tirzepatide (Zepbound), these popular medications — more commonly known as glucagon-like peptide 1 (GLP-1) agonists — have become game changers for shedding excess pounds.
Aside from obesity indications, both drugs have been approved to treat type 2 diabetes under different brand names and have a growing list of other potential benefits, such as reducing inflammation and depression.
While there’s limited data to support the use of GLP-1 agonists for weight loss in cancer, some oncologists have begun carefully integrating the antiobesity agents into care and studying their effects in this patient population.
The reason: Research suggests that obesity can reduce the effectiveness of cancer therapies, especially in patients with breast cancer, and can increase the risk for treatment-related side effects.
The idea is that managing patients’ weight will improve their cancer outcomes, explained Lajos Pusztai, MD, PhD, a breast cancer specialist and professor of medicine at Yale School of Medicine in New Haven, Connecticut.
Although Dr. Pusztai and his oncology peers at Yale don’t yet use GPL-1 agonists, Neil Iyengar, MD, and colleagues have begun doing so to help some patients with breast cancer manage their weight. Dr. Iyengar estimates that a few hundred — almost 40% — of his patients are on the antiobesity drugs.
“For a patient who has really tried to reduce their weight and who is in the obese range, that’s where I think the use of these medications can be considered,” said Dr. Iyengar, a breast cancer oncologist at Memorial Sloan Kettering Cancer Center in New York City.
Why GLP-1s in Cancer?
GLP-1 is a hormone that the small intestine releases after eating. GLP-1 agonists work by mimicking GLP-1 to trigger the release of insulin and reduce the production of glucagon — two processes that help regulate blood sugar.
These agents, such as Wegovy (or Ozempic when prescribed for diabetes), also slow gastric emptying and can make people feel fuller longer.
Zebound (or Mounjaro for type 2 diabetes) is considered a dual GLP-1 and glucose-dependent insulinotropic polypeptide agonist, which may enhance its weight loss benefits.
In practice, however, these drugs can increase nausea and vomiting from chemotherapy, so Dr. Iyengar typically has patients use them afterwards, during maintenance treatment.
Oncologists don’t prescribe the drugs themselves but instead refer patients to endocrinologists or weight management centers that then write the prescriptions. Taking these drugs involves weekly subcutaneous injections patients can administer themselves.
Endocrinologist Emily Gallagher, MD, PhD, of Mount Sinai Hospital in New York City, estimates she has prescribed the antiobesity drugs to a few hundred patients with cancer and, like Dr. Iyengar, uses the drugs during maintenance treatment with hormone therapy for breast cancer. She also has used these agents in patients with prostate and endometrial cancers and has found the drugs can help counter steroid weight gain in multiple myeloma.
But, to date, the evidence for using GPL-1 agonists in cancer remains limited and the practice has not yet become widespread.
Research largely comes down to a few small retrospective studies in patients with breast cancer receiving aromatase inhibitors. Although no safety issues have emerged so far, these initial reports suggest that the drugs lead to significantly less weight loss in patients with cancer compared to the general population.
Dr. Iyengar led one recent study, presented at the 2024 annual meeting of the American Society of Clinical Oncology, in which he and his team assessed outcomes in 75 women with breast cancer who received a GLP-1 agonist. Almost 80% of patients had diabetes, and 60% received hormone therapy, most commonly an aromatase inhibitor. Patients’ median body mass index (BMI) at baseline was 34 kg/m2 (range, 23-50 kg/m2).
From baseline, patients lost 6.2 kg, on average, or about 5% of their total body weight, 12 months after initiating GLP-1 therapy.
In contrast, phase 3 trials show much higher mean weight loss — about two times — in patients without cancer.
Another recent study also reported modest weight loss results in patients with breast cancer undergoing endocrine therapy. The researchers reported that, at 12 months, Wegovy led to 4.34% reduction in BMI, compared with a 14% change reported in the general population. Zebound, however, was associated with a 2.31% BMI increase overall — though some patients did experience a decrease — compared with a 15% reduction in the general population.
“These findings indicate a substantially reduced weight loss efficacy in breast cancer patients on endocrine therapy compared to the general population,” the authors concluded.
It’s unclear why the drugs appear to not work as well in patients with cancer. It’s possible that hormone therapy or metabolic changes interfere with their effectiveness, given that some cancer therapies lead to weight gain. Steroids and hormone therapies, for instance, often increase appetite, and some treatments can slow patients’ metabolism or lead to fatigue, which can make it harder to exercise.
Patients with cancer may need a higher dose of GLP-1 agonists to achieve similar weight loss to the general population, Dr. Iyengar noted.
However, Dr. Gallagher said, in her own experience, she hasn’t found the drugs to be less effective in patients with cancer, especially the newer agents, like Wegovy and Zepbound.
As for safety, Wegovy and Zepbound both carry a black box warning for thyroid C-cell tumors, including medullary thyroid carcinoma. (Recent research, however, has found that GLP-1 agonists do not increase thyroid cancer risk).
These antiobesity agents are also contraindicated in patients with a personal or family history of medullary thyroid carcinoma and in patients who have multiple endocrine neoplasia syndrome type 2, which is associated with medullary thyroid carcinoma.
Dr. Gallagher hasn’t seen any secondary tumors — thyroid or otherwise — in her patients with cancer, but she follows the labeling contraindications. Dr. Iyengar also noted that more recent and larger data sets have shown no impact on this risk, which may not actually exist, he said
Dr. Gallagher remains cautious about using GPL-1 agonists in patients who have had bariatric surgery because these agents can compound the slower gastric emptying and intestinal transit from surgery, potentially leading to gastrointestinal obstructions.
Looking ahead, GPL-1 manufacturers are interested in adding cancer indications to the drug labeling. Both Dr. Iyengar and Dr. Gallagher said their institutions are in talks with companies to participate in large, multicenter, global phase 3 trials.
Dr. Iyengar welcomes the efforts, not only to test the effectiveness of GPL-1 agonists in oncology but also to “nail down” their safety in cancer.
“I don’t think that there’s mechanistically anything that’s particularly worrisome,” and current observations suggest that these drugs are likely to be safe, Dr. Iyengar said. Even so, “GLP-1 agonists do a lot of things that we don’t fully understand yet.”
The bigger challenge, Dr. Iyengar noted, is that companies will have to show a sizable benefit to using these drugs in patients with cancer to get the Food and Drug Administration’s approval. And to move the needle on cancer-specific outcomes, these antiobesity drugs will need to demonstrate significant, durable weight loss in patients with cancer.

Does Medicare Advantage Offer Higher-Value Chemotherapy?
TOPLINE:
METHODOLOGY:
- Private Medicare Advantage plans enroll more than half of the Medicare population, but it is unknown if or how the cost restrictions they impose affect chemotherapy, which accounts for a large portion of cancer care costs.
- Researchers conducted a cohort study using national Medicare data from January 2015 to December 2019 to look at Medicare Advantage enrollment and treatment patterns for patients with cancer receiving chemotherapy.
- The study included 96,501 Medicare Advantage enrollees and 206,274 traditional Medicare beneficiaries who initiated chemotherapy between January 2016 and December 2019 (mean age, ~73 years; ~56% women; Hispanic individuals, 15% and 8%; Black individuals, 15% and 8%; and White individuals, 75% and 86%, respectively).
- Resource use and care quality were measured during a 6-month period following chemotherapy initiation, and survival days were measured 18 months after beginning chemotherapy.
- Resource use measures included hospital inpatient services, outpatient care, prescription drugs, hospice services, and chemotherapy services. Quality measures included chemotherapy-related emergency visits and hospital admissions, as well as avoidable emergency visits and preventable hospitalizations.
TAKEAWAY:
- Medicare Advantage plans had lower resource use than traditional Medicare per enrollee with cancer undergoing chemotherapy ($8718 lower; 95% CI, $8343-$9094).
- The lower resource use was largely caused by fewer chemotherapy visits and less expensive chemotherapy per visit in Medicare Advantage plans ($5032 lower; 95% CI, $4772-$5293).
- Medicare Advantage enrollees had 2.5 percentage points fewer chemotherapy-related emergency department visits and 0.7 percentage points fewer chemotherapy-related hospitalizations than traditional Medicare beneficiaries.
- There was no clinically meaningful difference in survival between Medicare Advantage and traditional Medicare beneficiaries during the 18 months following chemotherapy initiation.
IN PRACTICE:
“Our new finding is that MA [Medicare Advantage] plans had lower resource use than TM [traditional Medicare] among enrollees with cancer undergoing chemotherapy — a serious condition managed by specialists and requiring expensive treatments. This suggests that MA’s cost advantages over TM are not limited to conditions for which low-cost primary care management can avoid costly services,” the authors wrote.
SOURCE:
The study was led by Yamini Kalidindi, PhD, McDermott+ Consulting, Washington, DC. It was published online on September 20, 2024, in JAMA Network Open (doi: 10.1001/jamanetworkopen.2024.34707), with a commentary.
LIMITATIONS:
The study’s findings may be affected by unobserved patient characteristics despite the use of inverse-probability weighting. The exclusion of Medicare Advantage enrollees in contracts with incomplete encounter data limits the generalizability of the results. The study does not apply to beneficiaries without Part D drug coverage. Quality measures were limited to those available from claims and encounter data, lacking information on patients’ cancer stage. The 18-month measure of survival might not adequately capture survival differences associated with early-stage cancers. The study did not measure whether patient care followed recommended guidelines.
DISCLOSURES:
Various authors reported grants from the National Institute on Aging, the National Institutes of Health, The Commonwealth Fund, Arnold Ventures, the National Cancer Institute, the Department of Defense, and the National Institute of Health Care Management.

AACR Cancer Progress Report: Big Strides and Big Gaps
The AACR’s 216-page report — an annual endeavor now in its 14th year — focused on the “tremendous” strides made in cancer care, prevention, and early detection and highlighted areas where more research and attention are warranted.
One key area is funding. For the first time since 2016, federal funding for the National Institutes of Health (NIH) and National Cancer Institute (NCI) decreased in the past year. The cuts followed nearly a decade of funding increases that saw the NIH budget expand by nearly $15 billion, and that allowed for a “rapid pace and broad scope” of advances in cancer, AACR’s chief executive officer Margaret Foti, MD, PhD, said during a press briefing.
These recent cuts “threaten to curtail the medical progress seen in recent years and stymie future advancements,” said Dr. Foti, who called on Congress to commit to funding cancer research at significant and consistent levels to “maintain the momentum of progress against cancer.”
Inside the Report: Big Progress
Overall, advances in prevention, early detection, and treatment have helped catch more cancers earlier and save lives.
According to the AACR report, the age-adjusted overall cancer death rate in the United States fell by 33% between 1991 and 2021, meaning about 4.1 million cancer deaths were averted. The overall cancer death rate for children and adolescents has declined by 24% in the past 2 decades. The 5-year relative survival rate for children diagnosed with cancer in the US has improved from 58% for those diagnosed in the mid-1970s to 85% for those diagnosed between 2013 and 2019.
The past fiscal year has seen many new approvals for cancer drugs, diagnostics, and screening tests. From July 1, 2023, to June 30, 2024, the Food and Drug Administration (FDA) approved 15 new anticancer therapeutics, as well as 15 new indications for previously approved agents, one new imaging agent, several artificial intelligence (AI) tools to improve early cancer detection and diagnosis, and two minimally invasive tests for assessing inherited cancer risk or early cancer detection, according to the report.
“Cancer diagnostics are becoming more sophisticated,” AACR president Patricia M. LoRusso, DO, PhD, said during the briefing. “New technologies, such as spatial transcriptomics, are helping us study tumors at a cellular level, and helping to unveil things that we did not initially even begin to understand or think of. AI-based approaches are beginning to transform cancer detection, diagnosis, clinical decision-making, and treatment response monitoring.”
The report also highlights the significant progress in many childhood and adolescent/young adult cancers, Dr. LoRusso noted. These include FDA approvals for two new molecularly targeted therapeutics: tovorafenib for children with certain types of brain tumor and repotrectinib for children with a wide array of cancer types that have a specific genetic alteration known as NTRK gene fusion. It also includes an expanded approval for eflornithine to reduce the risk for relapse in children with high-risk neuroblastoma.
“Decades — decades — of basic research discoveries, have led to these clinical breakthroughs,” she stressed. “These gains against cancer are because of the rapid progress in our ability to decode the cancer genome, which has opened new and innovative avenues for drug development.”
The Gaps
Even with progress in cancer prevention, early detection, and treatment, cancer remains a significant issue.
“In 2024, it is estimated that more than 2 million new cases of cancer will be diagnosed in the United States. More than 611,000 people will die from the disease,” according to the report.
The 2024 report shows that incidence rates for some cancers are increasing in the United States, including vaccine-preventable cancers such as human papillomavirus (HPV)–associated oral cancers and, in young adults, cervical cancers. A recent analysis also found that overall cervical cancer incidence among women aged 30-34 years increased by 2.5% a year between 2012 and 2019.
Furthermore, despite clear evidence demonstrating that the HPV vaccine reduces cervical cancer incidence, uptake has remained poor, with only 38.6% of US children and adolescents aged 9-17 years receiving at least one dose of the vaccine in 2022.
Early-onset cancers are also increasing. Rates of breast, colorectal, and other cancers are on the rise in adults younger than 50 years, the report noted.
The report also pointed to data that 40% of all cancer cases in the United States can be attributed to preventable factors, such as smoking, excess body weight, and alcohol. However, our understanding of these risk factors has improved. Excessive levels of alcohol consumption have, for instance, been shown to increase the risk for six different types of cancer: certain types of head and neck cancer, esophageal squamous cell carcinoma, and breast, colorectal, liver, and stomach cancers.
Financial toxicity remains prevalent as well.
The report explains that financial hardship following a cancer diagnosis is widespread, and the effects can last for years. In fact, more than 40% of patients can spend their entire life savings within the first 2 years of cancer treatment. Among adult survivors of childhood cancers, 20.7% had trouble paying their medical bills, 29.9% said they had been sent to debt collection for unpaid bills, 14.1% had forgone medical care, and 26.8% could not afford nutritious meals.
For young cancer survivors, the lifetime costs associated with a diagnosis of cancer are substantial, reaching an average of $259,324 per person.
On a global level, it is estimated that from 2020 to 2050, the cumulative economic burden of cancer will be $25.2 trillion.
The Path Forward
Despite these challenges, Dr. LoRusso said, “it is unquestionable that we are in a time of unparalleled opportunities in cancer research.
“I am excited about what the future holds for cancer research, and especially for patient care,” she said.
However, funding commitments are needed to avoid impeding this momentum and losing a “talented and creative young workforce” that has brought new ideas and new technologies to the table.
Continued robust funding will help “to markedly improve cancer care, increase cancer survivorship, spur economic growth, and maintain the United States’ position as the global leader in science and medical research,” she added.
The AACR report specifically calls on Congress to:
- Appropriate at least $51.3 billion in fiscal year 2025 for the base budget of the NIH and at least $7.934 billion for the NCI.
- Provide $3.6 billion in dedicated funding for Cancer Moonshot activities through fiscal year 2026 in addition to other funding, consistent with the President’s fiscal year 2025 budget.
- Appropriate at least $472.4 million in fiscal year 2025 for the CDC’s Division of Cancer Prevention to support comprehensive cancer control, central cancer registries, and screening and awareness programs for specific cancers.
- Allocate $55 million in funding for the Oncology Center of Excellence at FDA in fiscal year 2025 to provide regulators with the staff and tools necessary to conduct expedited review of cancer-related medical products.
By working together with Congress and other stakeholders, “we will be able to accelerate the pace of progress and make major strides toward the lifesaving goal of preventing and curing all cancers at the earliest possible time,” Dr. Foti said. “I believe if we do that ... one day we will win this war on cancer.”

According to the AACR report, the age-adjusted overall cancer death rate in the United States fell by 33% between 1991 and 2021, meaning about 4.1 million cancer deaths were averted. The overall cancer death rate for children and adolescents has declined by 24% in the past 2 decades. The 5-year relative survival rate for children diagnosed with cancer in the US has improved from 58% for those diagnosed in the mid-1970s to 85% for those diagnosed between 2013 and 2019.
The past fiscal year has seen many new approvals for cancer drugs, diagnostics, and screening tests. From July 1, 2023, to June 30, 2024, the Food and Drug Administration (FDA) approved 15 new anticancer therapeutics, as well as 15 new indications for previously approved agents, one new imaging agent, several artificial intelligence (AI) tools to improve early cancer detection and diagnosis, and two minimally invasive tests for assessing inherited cancer risk or early cancer detection, according to the report.
“Cancer diagnostics are becoming more sophisticated,” AACR president Patricia M. LoRusso, DO, PhD, said during the briefing. “New technologies, such as spatial transcriptomics, are helping us study tumors at a cellular level, and helping to unveil things that we did not initially even begin to understand or think of. AI-based approaches are beginning to transform cancer detection, diagnosis, clinical decision-making, and treatment response monitoring.”
The report also highlights the significant progress in many childhood and adolescent/young adult cancers, Dr. LoRusso noted. These include FDA approvals for two new molecularly targeted therapeutics: tovorafenib for children with certain types of brain tumor and repotrectinib for children with a wide array of cancer types that have a specific genetic alteration known as NTRK gene fusion. It also includes an expanded approval for eflornithine to reduce the risk for relapse in children with high-risk neuroblastoma.
“Decades — decades — of basic research discoveries, have led to these clinical breakthroughs,” she stressed. “These gains against cancer are because of the rapid progress in our ability to decode the cancer genome, which has opened new and innovative avenues for drug development.”
The Gaps
Even with progress in cancer prevention, early detection, and treatment, cancer remains a significant issue.
“In 2024, it is estimated that more than 2 million new cases of cancer will be diagnosed in the United States. More than 611,000 people will die from the disease,” according to the report.
The 2024 report shows that incidence rates for some cancers are increasing in the United States, including vaccine-preventable cancers such as human papillomavirus (HPV)–associated oral cancers and, in young adults, cervical cancers. A recent analysis also found that overall cervical cancer incidence among women aged 30-34 years increased by 2.5% a year between 2012 and 2019.
Furthermore, despite clear evidence demonstrating that the HPV vaccine reduces cervical cancer incidence, uptake has remained poor, with only 38.6% of US children and adolescents aged 9-17 years receiving at least one dose of the vaccine in 2022.
Early-onset cancers are also increasing. Rates of breast, colorectal, and other cancers are on the rise in adults younger than 50 years, the report noted.
The report also pointed to data that 40% of all cancer cases in the United States can be attributed to preventable factors, such as smoking, excess body weight, and alcohol. However, our understanding of these risk factors has improved. Excessive levels of alcohol consumption have, for instance, been shown to increase the risk for six different types of cancer: certain types of head and neck cancer, esophageal squamous cell carcinoma, and breast, colorectal, liver, and stomach cancers.
Financial toxicity remains prevalent as well.
The report explains that financial hardship following a cancer diagnosis is widespread, and the effects can last for years. In fact, more than 40% of patients can spend their entire life savings within the first 2 years of cancer treatment. Among adult survivors of childhood cancers, 20.7% had trouble paying their medical bills, 29.9% said they had been sent to debt collection for unpaid bills, 14.1% had forgone medical care, and 26.8% could not afford nutritious meals.
For young cancer survivors, the lifetime costs associated with a diagnosis of cancer are substantial, reaching an average of $259,324 per person.
On a global level, it is estimated that from 2020 to 2050, the cumulative economic burden of cancer will be $25.2 trillion.
The Path Forward
Despite these challenges, Dr. LoRusso said, “it is unquestionable that we are in a time of unparalleled opportunities in cancer research.
“I am excited about what the future holds for cancer research, and especially for patient care,” she said.
However, funding commitments are needed to avoid impeding this momentum and losing a “talented and creative young workforce” that has brought new ideas and new technologies to the table.
Continued robust funding will help “to markedly improve cancer care, increase cancer survivorship, spur economic growth, and maintain the United States’ position as the global leader in science and medical research,” she added.
The AACR report specifically calls on Congress to:
- Appropriate at least $51.3 billion in fiscal year 2025 for the base budget of the NIH and at least $7.934 billion for the NCI.
- Provide $3.6 billion in dedicated funding for Cancer Moonshot activities through fiscal year 2026 in addition to other funding, consistent with the President’s fiscal year 2025 budget.
- Appropriate at least $472.4 million in fiscal year 2025 for the CDC’s Division of Cancer Prevention to support comprehensive cancer control, central cancer registries, and screening and awareness programs for specific cancers.
- Allocate $55 million in funding for the Oncology Center of Excellence at FDA in fiscal year 2025 to provide regulators with the staff and tools necessary to conduct expedited review of cancer-related medical products.
By working together with Congress and other stakeholders, “we will be able to accelerate the pace of progress and make major strides toward the lifesaving goal of preventing and curing all cancers at the earliest possible time,” Dr. Foti said. “I believe if we do that ... one day we will win this war on cancer.”

Cancer Risk: Are Pesticides the New Smoking?
Pesticides have transformed modern agriculture by boosting production yields and helping alleviate food insecurity amid rapid global population growth. However, from a public health perspective, exposure to pesticides has been linked to numerous harmful effects, including neurologic disorders like Parkinson’s disease, weakened immune function, and an increased risk for cancer.
thus offering a limited perspective.
A comprehensive assessment of how pesticide use affects cancer risk across a broader population has yet to be conducted.
A recent population-level study aimed to address this gap by evaluating cancer risks in the US population using a model that accounts for pesticide use and adjusts for various factors. The goal was to identify regional disparities in exposure and contribute to the development of public health policies that protect populations from potential harm.
Calculating Cancer Risk
Researchers developed a model using several data sources to estimate the additional cancer risk from agricultural pesticide use. Key data included:
- Pesticide use data from the US Geological Survey in 2019, which covered 69 agricultural pesticides across 3143 counties
- Cancer incidence rates per 100,000 people, which were collected between 2015 and 2019 by the National Institutes of Health and the Centers for Disease Control and Prevention; these data covered various cancers, including bladder, colorectal, leukemia, lung, non-Hodgkin lymphoma, and pancreatic cancers
- Covariates, including smoking prevalence, the Social Vulnerability Index, agricultural land use, and total US population in 2019
Pesticide use profile patterns were developed using latent class analysis, a statistical method used to identify homogeneous subgroups within a heterogeneous population. A generalized linear model then estimated how these pesticide use patterns and the covariates affected cancer incidence.
The model highlighted regions with the highest and lowest “additional” cancer risks linked to pesticide exposure, calculating the estimated increase in cancer cases per year that resulted from variations in agricultural pesticide use.
Midwest Most Affected
While this model doesn’t establish causality or assess individual risk, it reveals regional trends in the association between pesticide use patterns and cancer incidence from a population-based perspective.
The Midwest, known for its high corn production, emerged as the region most affected by pesticide use. Compared with regions with the lowest risk, the Midwest faced an additional 154,541 cancer cases annually across all types. For colorectal and pancreatic cancers, the yearly increases were 20,927 and 3835 cases, respectively. Similar trends were observed for leukemia and non-Hodgkin lymphoma.
Pesticides vs Smoking
The researchers also estimated the additional cancer risk related to smoking, using the same model. They found that pesticides contributed to a higher risk for cancer than smoking in several cases.
The most significant difference was observed with non-Hodgkin lymphoma, where pesticides were linked to 154.1% more cases than smoking. For all cancers combined, as well as bladder cancer and leukemia, the increases were moderate: 18.7%, 19.3%, and 21.0%, respectively.
This result highlights the importance of considering pesticide exposure alongside smoking when studying cancer risks.
Expanding Scope of Research
Some limitations of this study should be noted. Certain counties lacked complete data, and there was heterogeneity in the size and population of the counties studied. The research also did not account for seasonal and migrant workers, who are likely to be heavily exposed. In addition, the data used in the study were not independently validated, and they could not be used to assess individual risk.
The effect of pesticides on human health is a vast and critical field of research, often focusing on a limited range of pesticides or specific cancers. This study stands out by taking a broader, more holistic approach, aiming to highlight regional inequalities and identify less-studied pesticides that could be future research priorities.
Given the significant public health impact, the authors encouraged the authorities to share these findings with the most vulnerable communities to raise awareness.
