When Childhood Cancer Survivors Face Sexual Challenges
Childhood cancers represent a diverse group of neoplasms, and thanks to advances in treatment, survival rates have improved significantly. Today, more than 80%-85% of children diagnosed with cancer in developed countries survive into adulthood.
This increase in survival has brought new challenges, however. Compared with the general population, childhood cancer survivors (CCS) are at a notably higher risk for early mortality, developing secondary cancers, and experiencing various long-term clinical and psychosocial issues stemming from their disease or its treatment.
Long-term follow-up care for CCS is a complex and evolving field. Despite ongoing efforts to establish global and national guidelines, current evidence indicates that the care and management of these patients remain suboptimal.
The disruptions caused by cancer and its treatment can interfere with normal physiological and psychological development, leading to issues with sexual function. This aspect of health is critical as it influences not just physical well-being but also psychosocial, developmental, and emotional health.
Characteristics and Mechanisms
Sexual functioning encompasses the physiological and psychological aspects of sexual behavior, including desire, arousal, orgasm, sexual pleasure, and overall satisfaction.
As CCS reach adolescence or adulthood, they often face sexual and reproductive issues, particularly as they enter romantic relationships.
Sexual functioning is a complex process that relies on the interaction of various factors, including physiological health, psychosexual development, romantic relationships, body image, and desire.
Despite its importance, the impact of childhood cancer on sexual function is often overlooked, even though cancer and its treatments can have lifelong effects.
Sexual Function in CCS
A recent review aimed to summarize the existing research on sexual function among CCS, highlighting assessment tools, key stages of psychosexual development, common sexual problems, and the prevalence of sexual dysfunction.
The review study included 22 studies published between 2000 and 2022, comprising two qualitative, six cohort, and 14 cross-sectional studies.
Most CCS reached all key stages of psychosexual development at an average age of 29.8 years. Although some milestones were achieved later than is typical, many survivors felt they reached these stages at the appropriate time. Sexual initiation was less common among those who had undergone intensive neurotoxic treatments, such as those diagnosed with brain tumors or leukemia in childhood.
In a cross-sectional study of CCS aged 17-39 years, about one third had never engaged in sexual intercourse, 41.4% reported never experiencing sexual attraction, 44.8% were dissatisfied with their sex lives, and many rarely felt sexually attractive to others. Another study found that common issues among CCS included a lack of interest in sex (30%), difficulty enjoying sex (24%), and difficulty becoming aroused (23%). However, comparing and analyzing these problems was challenging due to the lack of standardized assessment criteria.
The prevalence of sexual dysfunction among CCS ranged from 12.3% to 46.5%. For males, the prevalence ranged from 12.3% to 54.0%, while for females, it ranged from 19.9% to 57.0%.
Factors Influencing Sexual Function
The review identified the following four categories of factors influencing sexual function in CCS: Demographic, treatment-related, psychological, and physiological.
Demographic factors: Gender, age, education level, relationship status, income level, and race all play roles in sexual function.
Female survivors reported more severe sexual dysfunction and poorer sexual health than did male survivors. Age at cancer diagnosis, age at evaluation, and the time since diagnosis were closely linked to sexual experiences. Patients diagnosed with cancer during childhood tended to report better sexual function than those diagnosed during adolescence.
Treatment-related factors: The type of cancer and intensity of treatment, along with surgical history, were significant factors. Surgeries involving the spinal cord or sympathetic nerves, as well as a history of prostate or pelvic surgery, were strongly associated with erectile dysfunction in men. In women, pelvic surgeries and treatments to the pelvic area were commonly linked to sexual dysfunction.
The association between treatment intensity and sexual function was noted across several studies, although the results were not always consistent. For example, testicular radiation above 10 Gy was positively correlated with sexual dysfunction. Women who underwent more intensive treatments were more likely to report issues in multiple areas of sexual function, while men in this group were less likely to have children.
Among female CCS, certain types of cancer, such as germ cell tumors, renal tumors, and leukemia, present a higher risk for sexual dysfunction. Women who had CNS tumors in childhood frequently reported problems like difficulty in sexual arousal, low sexual satisfaction, infrequent sexual activity, and fewer sexual partners, compared with survivors of other cancers. Survivors of acute lymphoblastic leukemia and those who underwent hematopoietic stem cell transplantation (HSCT) also showed varying degrees of impaired sexual function, compared with the general population. The HSCT group showed significant testicular damage, including reduced testicular volumes, low testosterone levels, and low sperm counts.
Psychological factors: These factors, such as emotional distress, play a significant role in sexual dysfunction among CCS. Symptoms like anxiety, nervousness during sexual activity, and depression are commonly reported by those with sexual dysfunction. The connection between body image and sexual function is complex. Many CCS with sexual dysfunction express concern about how others, particularly their partners, perceived their altered body image due to cancer and its treatment.
Physiological factors: In male CCS, low serum testosterone levels and low lean muscle mass are linked to an increased risk for sexual dysfunction. Treatments involving alkylating agents or testicular radiation, and surgery or radiotherapy targeting the genitourinary organs or the hypothalamic-pituitary region, can lead to various physiological and endocrine disorders, contributing to sexual dysfunction. Despite these risks, there is a lack of research evaluating sexual function through the lens of the hypothalamic-pituitary-gonadal axis and neuroendocrine pathways.

Immunotherapy May Be Overused in Dying Patients With Cancer
Chemotherapy has fallen out of favor for treating cancer toward the end of life. The toxicity is too high, and the benefit, if any, is often too low.
Immunotherapy, however, has been taking its place.
This means “there are patients who are getting immunotherapy who shouldn’t,” said Yale University, New Haven, Connecticut, surgical oncologist Sajid Khan, MD, senior investigator on a recent study that highlighted the growing use of these agents in patients’ last month of life.
What’s driving this trend, and how can oncologists avoid overtreatment with immunotherapy at the end of life?
The N-of-1 Patient
With immunotherapy at the end of life, “each of us has had our N-of-1” where a patient bounces back with a remarkable and durable response, said Don Dizon, MD, a gynecologic oncologist at Brown University, Providence, Rhode Island.
He recalled a patient with sarcoma who did not respond to chemotherapy. But after Dr. Dizon started her on immunotherapy, everything turned around. She has now been in remission for 8 years and counting.
The possibility of an unexpected or remarkable responder is seductive. And the improved safety of immunotherapy over chemotherapy adds to the allure.
Meanwhile, patients are often desperate. It’s rare for someone to be ready to stop treatment, Dr. Dizon said. Everybody “hopes that they’re going to be the exceptional responder.”
At the end of the day, the question often becomes: “Why not try immunotherapy? What’s there to lose?”
This thinking may be prompting broader use of immunotherapy in late-stage disease, even in instances with no Food and Drug Administration indication and virtually no supportive data, such as for metastatic ovarian cancer, Dr. Dizon said.
Back to Earth
The problem with the hopeful approach is that end-of-life turnarounds with immunotherapy are rare, and there’s no way at the moment to predict who will have one, said Laura Petrillo, MD, a palliative care physician at Massachusetts General Hospital, Boston.
Even though immunotherapy generally comes with fewer adverse events than chemotherapy, catastrophic side effects are still possible.
Dr. Petrillo recalled a 95-year-old woman with metastatic cancer who was largely asymptomatic.
She had a qualifying mutation for a checkpoint inhibitor, so her oncologist started her on one. The patient never bounced back from the severe colitis the agent caused, and she died of complications in the hospital.
Although such reactions with immunotherapy are uncommon, less serious problems caused by the agents can still have a major impact on a person’s quality of life. Low-grade diarrhea, for instance, may not sound too bad, but in a patient’s daily life, it can translate to six or more episodes a day.
Even with no side effects, prescribing immunotherapy can mean that patients with limited time left spend a good portion of it at an infusion clinic instead of at home. These patients are also less likely to be referred to hospice and more likely to be admitted to and die in the hospital.
And with treatments that can cost $20,000 per dose, financial toxicity becomes a big concern.
In short, some of the reasons why chemotherapy is not recommended at the end of life also apply to immunotherapy, Dr. Petrillo said.
Prescribing Decisions
Recent research highlights the growing use of immunotherapy at the end of life.
Dr. Khan’s retrospective study found, for instance, that the percentage of patients starting immunotherapy in the last 30 days of life increased by about fourfold to fivefold over the study period for the three cancers analyzed — stage IV melanoma, lung, and kidney cancers.
Among the population that died within 30 days, the percentage receiving immunotherapy increased over the study periods — 0.8%-4.3% for melanoma, 0.9%-3.2% for NSCLC, and 0.5%-2.6% for kidney cell carcinoma — prompting the conclusion that immunotherapy prescriptions in the last month of life are on the rise.
Prescribing immunotherapy in patients who ultimately died within 1 month occurred more frequently at low-volume, nonacademic centers than at academic or high-volume centers, and outcomes varied by practice setting.
Patients had better survival outcomes overall when receiving immunotherapy at academic or high-volume centers — a finding Dr. Khan said is worth investigating further. Possible explanations include better management of severe immune-related side effects at larger centers and more caution when prescribing immunotherapy to “borderline” candidates, such as those with several comorbidities.
Importantly, given the retrospective design, Dr. Khan and colleagues already knew which patients prescribed immunotherapy died within 30 days of initiating treatment.
More specifically, 5192 of 71,204 patients who received immunotherapy (7.3%) died within a month of initiating therapy, while 66,012 (92.7%) lived beyond that point.
The study, however, did not assess how the remaining 92.7% who lived beyond 30 days fared on immunotherapy and the differences between those who lived less than 30 days and those who survived longer.
Knowing the outcome of patients at the outset of the analysis still leaves open the question of when immunotherapy can extend life and when it can’t for the patient in front of you.
To avoid overtreating at the end of life, it’s important to have “the same standard that you have for giving chemotherapy. You have to treat it with the same respect,” said Moshe Chasky, MD, a community medical oncologist with Alliance Cancer Specialists in Philadelphia, Pennsylvania. “You can’t just be throwing” immunotherapy around “at the end of life.”
While there are no clear predictors of risk and benefit, there are some factors to help guide decisions.
As with chemotherapy, Dr. Petrillo said performance status is key. Dr. Petrillo and colleagues found that median overall survival with immune checkpoint inhibitors for advanced non–small cell lung cancer was 14.3 months in patients with an Eastern Cooperative Oncology Group performance score of 0-1 but only 4.5 months with scores of ≥ 2.
Dr. Khan also found that immunotherapy survival is, unsurprisingly, worse in patients with high metastatic burdens and more comorbidities.
“You should still consider immunotherapy for metastatic melanoma, non–small cell lung cancer, and renal cell carcinoma,” Dr. Khan said. The message here is to “think twice before using” it, especially in comorbid patients with widespread metastases.
“Just because something can be done doesn’t always mean it should be done,” he said.
At Yale, when Dr. Khan works, immunotherapy decisions are considered by a multidisciplinary tumor board. At Mass General, immunotherapy has generally moved to the frontline setting, and the hospital no longer prescribes checkpoint inhibitors to hospitalized patients because the cost is too high relative to the potential benefit, Dr. Petrillo explained.
Still, with all the uncertainties about risk and benefit, counseling patients is a challenge. Dr. Dizon called it “the epitome of shared decision-making.”
Dr. Petrillo noted that it’s critical not to counsel patients based solely on the anecdotal patients who do surprisingly well.
“It’s hard to mention that and not have that be what somebody anchors on,” she said. But that speaks to “how desperate people can feel, how hopeful they can be.”
Dr. Khan, Dr. Petrillo, and Dr. Chasky all reported no relevant conflicts of interest.

Possible explanations include better management of severe immune-related side effects at larger centers and more caution when prescribing immunotherapy to “borderline” candidates, such as those with several comorbidities.
Importantly, given the retrospective design, Dr. Khan and colleagues already knew which patients prescribed immunotherapy died within 30 days of initiating treatment.
More specifically, 5192 of 71,204 patients who received immunotherapy (7.3%) died within a month of initiating therapy, while 66,012 (92.7%) lived beyond that point.
The study, however, did not assess how the remaining 92.7% who lived beyond 30 days fared on immunotherapy and the differences between those who lived less than 30 days and those who survived longer.
Knowing the outcome of patients at the outset of the analysis still leaves open the question of when immunotherapy can extend life and when it can’t for the patient in front of you.
To avoid overtreating at the end of life, it’s important to have “the same standard that you have for giving chemotherapy. You have to treat it with the same respect,” said Moshe Chasky, MD, a community medical oncologist with Alliance Cancer Specialists in Philadelphia, Pennsylvania. “You can’t just be throwing” immunotherapy around “at the end of life.”
While there are no clear predictors of risk and benefit, there are some factors to help guide decisions.
As with chemotherapy, Dr. Petrillo said performance status is key. Dr. Petrillo and colleagues found that median overall survival with immune checkpoint inhibitors for advanced non–small cell lung cancer was 14.3 months in patients with an Eastern Cooperative Oncology Group performance score of 0-1 but only 4.5 months with scores of ≥ 2.
Dr. Khan also found that immunotherapy survival is, unsurprisingly, worse in patients with high metastatic burdens and more comorbidities.
“You should still consider immunotherapy for metastatic melanoma, non–small cell lung cancer, and renal cell carcinoma,” Dr. Khan said. The message here is to “think twice before using” it, especially in comorbid patients with widespread metastases.
“Just because something can be done doesn’t always mean it should be done,” he said.
At Yale, when Dr. Khan works, immunotherapy decisions are considered by a multidisciplinary tumor board. At Mass General, immunotherapy has generally moved to the frontline setting, and the hospital no longer prescribes checkpoint inhibitors to hospitalized patients because the cost is too high relative to the potential benefit, Dr. Petrillo explained.
Still, with all the uncertainties about risk and benefit, counseling patients is a challenge. Dr. Dizon called it “the epitome of shared decision-making.”
Dr. Petrillo noted that it’s critical not to counsel patients based solely on the anecdotal patients who do surprisingly well.
“It’s hard to mention that and not have that be what somebody anchors on,” she said. But that speaks to “how desperate people can feel, how hopeful they can be.”
Dr. Khan, Dr. Petrillo, and Dr. Chasky all reported no relevant conflicts of interest.

FDA Approves First Targeted Therapy for Gliomas With IDH Mutations
Specifically, the oral targeted inhibitor of IDH1 and IDH2 was approved for use after surgery in adults and children aged 12 years or older who have grade 2 astrocytoma or oligodendroglioma with a susceptible IDH1 or IDH2 mutation. According to the FDA, surgery includes biopsy, subtotal resection, or gross total resection.
Mutations in IDH1 are present in around 80% of grade 2 gliomas, whereas IDH2 mutations are more infrequent, occurring in about 4%.
Prior to the approval, which was based on progression-free survival (PFS) and safety findings from the pivotal phase 3 INDIGO trial, patients with this type of glioma had limited treatment options, said a Servier spokesperson.
The approval of vorasidenib marks “one of the biggest advances in low-grade glioma in more than two decades” and “will empower patients to take active control of their disease with a once-daily pill,” according to the spokesperson.
In the INDIGO trial, 331 patients were randomly assigned to receive 40 mg of vorasidenib once daily (n = 168) or placebo (n = 163). At a median follow-up of 14.2 months, the median PFS was more than twice as long among those who received vorasidenib vs placebo: 27.7 months vs 11.1 months, respectively (hazard ratio [HR] for disease progression or death, 0.39). The time to next intervention was also significantly longer with vorasidenib vs placebo (median not reached vs 17.8 months, respectively; HR, 0.26).
The 61% reduction in the risk for tumor progression or death observed in the trial represents “a significant sign of efficacy that has the potential to change the landscape in this disease,” first author Ingo K. Mellinghoff, MD, of Memorial Sloan Kettering Cancer Center, New York City, told this news organization in 2023, when presenting the findings at the 2023 American Society of Clinical Oncology conference. These findings were simultaneously published in The New England Journal of Medicine.
Glenn Lesser, MD, a discussant at the 2023 meeting, commented on the “striking” findings. The results are “statistically highly significant, and more importantly, they’re clinically very, very significant,” said Dr. Lesser, from Wake Forest Baptist Health in Winston-Salem, North Carolina.
Vorasidenib can also potentially delay the use of toxic chemotherapies and radiation for many years in patients with these tumors, Dr. Lesser added.
Adverse events of grade 3 or higher occurred in 22.8% of those who received vorasidenib and in 13.5% of those in the placebo group. Increased alanine aminotransferase levels of grade 3 or higher occurred in 9.6 vs 0% of patients in the groups, respectively.
The most common adverse reactions with vorasidenib, affecting at least 15% of treated patients, include fatigue, headache, COVID-19, musculoskeletal pain, diarrhea, nausea, and seizure. The most common grade 3 or 4 laboratory abnormalities were increased alanine aminotransferase, aspartate aminotransferase, gamma-glutamyl transpeptidase as well as decreased neutrophils.
The recommended dose of vorasidenib for adults is 40 mg given orally once daily until disease progression or unacceptable toxicity. In children aged 12 or older, the recommended dose is 40 mg given orally once daily for those weighing ≥ 40 kg, and 20 mg given orally once daily for those weighing < 40 kg.

FDA Approves First Engineered Cell Therapy for a Solid Tumor
Afami-cel — the first engineered cell therapy for a solid tumor — is indicated specifically for adults with unresectable or metastatic synovial sarcoma who have received prior chemotherapy, are positive for several human leukocyte antigens (HLAs), and whose tumors express melanoma-associated antigen A4, as determined by FDA-authorized companion diagnostic devices.
The single-dose treatment targets solid tumors expressing melanoma-associated antigen A4, a protein highly expressed in synovial sarcoma.
Synovial sarcoma is a rare form of cancer, which affects about 1000 people in the US each year. Malignant cells develop and form a tumor in soft tissues, often in the extremities.
“Adults with metastatic synovial sarcoma, a life-threatening form of cancer, often face limited treatment options in addition to the risk of cancer spread or recurrence,” Nicole Verdun, MD, director of the Office of Therapeutic Products in the FDA’s Center for Biologics Evaluation and Research, said in the agency press release announcing the approval. “Today’s approval represents a significant milestone in the development of an innovative, safe and effective therapy for patients with this rare but potentially fatal disease.”
T-cell receptor therapy, like chimeric antigen receptor (CAR) T-cell (CAR-T) therapy, involves altering patient T cells to fight cancer. While CAR-T therapy inserts an artificial receptor to target a specific surface protein on cancer cells, the T-cell receptor therapy modifies existing receptors to recognize an array of antigens on the surface of cancer cells — a promising strategy for targeting solid tumors.
The accelerated approval of afami-cel was based on the phase 2 SPEARHEAD-1 trial in 44 patients with synovial sarcoma who received a single infusion of the therapy. The trial had enrolled 52 patients, but 8 did not receive afami-cel, including 3 who died and 1 who withdrew.
According to the FDA announcement, the overall response rate was 43.2%, with a median time to response of 4.9 weeks. The median duration of response was 6 months (95% CI, 4.6 months to not reached). Among patients who responded, 39% had a duration of response of 12 months or longer.
“These results suggest that a one-time treatment with afami-cel has the potential to extend life while allowing responders to go off chemotherapy,” said lead investigator Sandra D’Angelo, MD, a sarcoma specialist at Memorial Sloan Kettering Cancer Center in New York City, in a company press release.
The prescribing information includes a boxed warning for serious or fatal cytokine release syndrome.
The most common nonlaboratory adverse reactions, occurring in at least 20% of patients, included cytokine release syndrome, nausea, vomiting, fatigue, infections, pyrexia, constipation, dyspnea, tachycardia, hypotension, diarrhea, and edema. The most common grade 3 or 4 laboratory abnormalities, occurring in at least 20% of patients, included decreased lymphocyte count, neutrophil count, white cell blood count, red blood cell, and platelet count.
The recommended dose is between 2.68x109 to 10x109 MAGE-A4 T-cell receptor–positive T-cells. The FDA notice specifies not using a leukodepleting filter or prophylactic systemic corticosteroids.
The list price for the one-time therapy is $727,000, according to Fierce Pharma.

The Last 30 Days: How Oncologists’ Choices Affect End-of-Life Cancer Care
TOPLINE:
Patients treated by oncologists in the top quartile for end-of-life prescribing behavior were almost four and a half times more likely to receive end-of-life therapy than those treated by these specialists in the bottom quartile.
METHODOLOGY:
- Researchers analyzed data from the Surveillance, Epidemiology, and End Results (SEER)-Medicare database, focusing on patients who died of cancer between 2012 and 2017.
- A total of 17,609 patients with breast, lung, colorectal, or prostate cancer were included, treated by 960 oncologists across 388 practices.
- Patients were required to have had at least one systemic cancer therapy claim in the last 180 days of life, with the treating oncologist identified on the basis of the therapy claim closest to the time of death.
- The study used multilevel models to estimate oncologists’ rates of providing cancer therapy in the last 30 days of life, adjusting for patient characteristics and practice variation.
- Functional status was assessed on the basis of paid claims for durable medical equipment in the last 60 months of life, with scores categorized as 0, 1, ≥ 2, or unknown.
TAKEAWAY:
- Oncologists in the 95th percentile for high end-of-life prescribing behavior had a 45% adjusted rate of treating patients in the last 30 days of life, compared with 17% among those in the 5th percentile.
- Patients treated by high end-of-life prescribing oncologists had over four times higher odds of receiving systemic therapy in the last 30 days of life (odds ratio [OR], 4.42; 95% CI, 4.00-4.89).
- Higher end-of-life prescribing oncologists also had a higher proportion of patients hospitalized in the last 30 days of life than low prescribers (58% vs 51.9%).
- No significant association was found between oncologist prescribing behavior and patient race or ethnicity, except for Black patients who had lower odds of receiving treatment (OR, 0.77; P < .001).
IN PRACTICE:
“Given calls to rein in overutilization of end-of-life six to eight cancer therapies, our findings highlight an underappreciated area for further research: How treatment discontinuation before death is shaped by oncologists’ unique treatment propensities. Elucidating the reasons for this remarkable variability in oncologist treatment behavior could inform efforts to reduce end-of-life cancer treatment overutilization,” wrote the authors of the study.
SOURCE:
The study was led by Login S. George, PhD, Institute for Health, Health Care Policy and Aging Research, Rutgers University in New Brunswick, New Jersey. It was published online in Cancer.
LIMITATIONS:
The study’s reliance on SEER-Medicare data may limit the generalizability of the findings to patients with Medicare Advantage, private insurance, or Medicaid, as well as younger patients. The lack of data on patient preferences and other health characteristics could confound the results. The study focused on systemic therapies and may not be generalizable to other treatments such as clinical trial drugs, oral therapies, surgery, or radiation. The data from 2012 to 2017 may not reflect more recent trends in cancer treatment.
DISCLOSURES:
The study was supported by grants from the National Cancer Institute and the Rutgers Cancer Institute of New Jersey. George disclosed receiving grants from these organizations. Additional disclosures are noted in the original article.

Ancient Viruses in Our DNA Hold Clues to Cancer Treatment
according to a fascinating new study in Science Advances. Targeting these viral remnants still lingering in our DNA could lead to more effective cancer treatment with fewer side effects, the researchers said.
The study “gives a better understanding of how gene regulation can be impacted by these ancient retroviral sequences,” said Dixie Mager, PhD, scientist emeritus at the Terry Fox Laboratory at the British Columbia Cancer Research Institute, Vancouver, British Columbia, Canada. (Mager was not involved in the study.)
Long thought to be “junk” DNA with no biologic function, “endogenous retroviruses,” which have mutated over time and lost their ability to create the virus, are now known to regulate genes — allowing some genes to turn on and off. Research in recent years suggests they may play a role in diseases like cancer.
But scientists weren’t exactly sure what that role was, said senior study author Edward Chuong, PhD, a genome biologist at the University of Colorado Boulder.
Most studies have looked at whether endogenous retroviruses code for proteins that influence cancer. But these ancient viral strands usually don’t code for proteins at all.
Dr. Chuong took a different approach. Inspired by scientists who’ve studied how viral remnants regulate positive processes (immunity, brain development, or placenta development), he and his team explored whether some might regulate genes that, once activated, help cancer thrive.
Borrowing from epigenomic analysis data (data on molecules that alter gene expression) for 21 cancers mapped by the Cancer Genome Atlas, the researchers identified 19 virus-derived DNA sequences that bind to regulatory proteins more in cancer cells than in healthy cells. All of these could potentially act as gene regulators that promote cancer.
The researchers homed in on one sequence, called LTR10, because it showed especially high activity in several cancers, including lung and colorectal cancer. This DNA segment comes from a virus that entered our ancestors’ genome 30 million years ago, and it’s activated in a third of colorectal cancers.
Using the gene editing technology clustered regularly interspaced short palindromic repeats (CRISPR), Dr. Chuong’s team silenced LTR10 in colorectal cancer cells, altering the gene sequence so it couldn’t bind to regulatory proteins. Doing so dampened the activity of nearby cancer-promoting genes.
“They still behaved like cancer cells,” Dr. Chuong said. But “it made the cancer cells more susceptible to radiation. That would imply that the presence of that viral ‘switch’ actually helped those cancer cells survive radiation therapy.”
Previously, two studies had found that viral regulators play a role in promoting two types of cancer: Leukemia and prostate cancer. The new study shows these two cases weren’t flukes. All 21 cancers they looked at had at least one of those 19 viral elements, presumably working as cancer enhancers.
The study also identified what activates LTR10 to make it promote cancer. The culprit is a regulator protein called mitogen-activated protein (MAP) kinase, which is overactivated in about 40% of all human cancers.
Some cancer drugs — MAP kinase inhibitors — already target MAP kinase, and they’re often the first ones prescribed when a patient is diagnosed with cancer, Dr. Chuong said. As with many cancer treatments, doctors don’t know why they work, just that they do.
“By understanding the mechanisms in the cell, we might be able to make them work better or further optimize their treatment,” he said.
“MAP kinase inhibitors are really like a sledgehammer to the cell,” Dr. Chuong said — meaning they affect many cellular processes, not just those related to cancer.
“If we’re able to say that these viral switches are what’s important, then that could potentially help us develop a more targeted therapy that uses something like CRISPR to silence these viral elements,” he said. Or it could help providers choose a MAP kinase inhibitor from among the dozens available best suited to treat an individual patient and avoid side effects.
Still, whether the findings translate to real cancer patients remains to be seen. “It’s very, very hard to go the final step of showing in a patient that these actually make a difference in the cancer,” Dr. Mager said.
More lab research, human trials, and at least a few years will be needed before this discovery could help treat cancer. “Directly targeting these elements as a therapy would be at least 5 years out,” Dr. Chuong said, “partly because that application would rely on CRISPR epigenome editing technology that is still being developed for clinical use.”

FROM SCIENCE ADVANCES
Greater Transparency of Oncologists’ Pharma Relationships Needed
The findings reflect limited awareness in low-income countries about what scenarios constitute a conflict of interest, first author, Khalid El Bairi, MD, said during an interview. “There is a lack of training in ethics and integrity in medical schools [in countries in Africa], so people are not informed about conflicts of interest,” continued Dr. El Bairi, who presented the new research at the annual meeting of the American Society of Clinical Oncology. “There is also a lack of policies in universities and hospitals to guide clinicians about conflict of interest reporting.”
Overall, 58.5% of survey participants categorized honoraria as a conflict of interest that required disclosure, while 50% said the same of gifts from pharmaceutical representatives, and 44.5% identified travel grants for attending conferences as conflicts of interests. The report was published in JCO Global Oncology. Less often considered conflicts of interest were personal and institutional research funding, trips to conferences, consulting or advisory roles, food and beverages, expert testimony, and sample drugs provided by the pharmaceutical industry.
Just 24% of participants indicated that all of the listed items were deemed conflicts of interest. The survey — called Oncology Transparency Under Scrutiny and Tracking, or ONCOTRUST-1 — considered the perceptions of 200 oncologists, about 70% of whom practice in low- and middle-income countries.
What’s more, 37.5% of respondents identified fear of losing financial support as a reason not to report a conflict of interest. Still, 75% indicated that industry-sponsored speaking does not affect treatment decisions, and 60% said conflicts of interest do not impair objective appraisal of clinical trials.
Dr. El Bairi, a research associate in the department of medical oncology at Mohammed VI University Hospital, Oujda, Morocco, and his colleagues undertook the study in part because of an editorial published in The Lancet Oncology last year. First author Fidel Rubagumya, MD, a consultant oncologist and director of research at Rwanda Military Hospital, Kigali, and colleagues called for more research on the ties between oncologists and industry in Africa. The ONCOTRUST-1 findings set the stage for a planned follow-up study, which aims to compare views surrounding conflicts of interests between oncologists in different economic settings.
Open Payments Houses US Physicians’ Conflicts of Interest
To be sure, many authors of research published in major US journals are based outside of the United States. According to JAMA Network Open, 69% of submissions to the journal are from international authors. However, Dr. El Bairi also raised other potential signs of industry influence that he said need global discussion, such as the role of pharmaceutical companies in presentations of clinical trial findings at large cancer societies’ conferences, a shift toward progression-free survival as the endpoint in clinical cancer trials, and the rise of third-party writing assistance.
“There are two sides of the story,” Dr. El Bairi said. “The good side is that unfortunately, sometimes [industry money is] the only way for African oncologists to go abroad for training, to conferences for their continuous medical education. The bad is now we may harm patients, we might harm science by having conflicts of interest not reported.”
Unlike other countries, the United States has plentiful data on the scale of physicians’ financial conflicts of interest in the form of the Open Payments platform. Championed by Sen. Chuck Grassley (R-Iowa), the federal repository of payments to doctors and teaching hospitals by drug and medical device companies was established as part of the Affordable Care Act (ACA).
The health care reform law, which passed in 2010, requires pharmaceutical companies and medical device makers to report this information.
From 2013 to 2021, the pharmaceutical and medical device industry paid physicians $12.1 billion, according to a research letter published in JAMA in March of 2024 that reviewed Open Payments data.
Ranked by specialty, hematologists and oncologists received the fourth-largest amount of money in aggregate, the study shows. Their total of $825.8 million trailed only physicians in orthopedics ($1.36 billion), neurology and psychiatry ($1.32 billion) and cardiology ($1.29 billion). What’s more, this specialty had the biggest share of physicians taking industry money, with 74.2% of hematologists and oncologists receiving payments.
The payments from industry include fees for consulting services and speaking, as well as food and beverages, travel and lodging, education, gifts, grants, and honoraria.
Joseph S. Ross, MD, MHS, one of the JAMA study’s coauthors, said in an interview that the continued prevalence of such funding runs counter to the expectation behind the measure, which was that transparency would lead to physicians’ becoming less likely to accept a payment.
“We as a profession need to take a cold hard look in the mirror,” he said, referring to physicians in general.
Dr. Ross, professor of medicine at Yale University School of Medicine, New Haven, Connecticut, said he hopes that the profession will self-police, and that patients will make a bigger deal of the issue. Still, he acknowledged that “the vast majority” of patient advocacy groups, too, are funded by the pharmaceutical industry.
Exposing Industry Payments May Have Perverse Effect
A growing body of research explores the effect that physicians’ financial relationships with pharmaceutical companies can have on their prescribing practices. Indeed, oncologists taking industry payments seem to be more likely to prescribe nonrecommended and low-value drugs in some clinical settings, according to a study published in The BMJ last year.
That study’s first author, Aaron P. Mitchell, MD, a medical oncologist and assistant attending physician at Memorial Sloan Kettering Cancer Center, New York City, suggested in an interview that exposing industry payments to the sunlight may have had a perverse effect on physicians.
“There’s this idea of having license to do something,” Dr. Mitchell said, speaking broadly about human psychology rather than drawing on empirical data. “You might feel a little less bad about then prescribing more of that company’s drug, because the disclosure has already been done.”
The influence of pharmaceutical industry money on oncologists goes beyond what’s prescribed to which treatments get studied, approved, and recommended by guidelines, Dr. Mitchell said. He was also first author of a 2016 paper published in JAMA Oncology that found 86% of authors of the National Comprehensive Cancer Network guidelines had at least one conflict of interest reported on Open Systems in 2014.
Meanwhile, the fact that physicians’ payments from industry are a matter of public record on Open Systems has not guaranteed that doctors will disclose their conflicts of interest in other forums. A study published in JAMA earlier this year, for which Dr. Mitchell served as first author, found that almost one in three physicians endorsing drugs and devices on the social media platform X failed to disclose that the manufacturer paid them.
The lack of disclosure seems to extend beyond social media. A 2018 study published in JAMA Oncology found that 32% of oncologist authors of clinical drug trials for drugs approved over a 20-month period from 2016 to 2017 did not fully disclose payments from the trial sponsor when checked against the Open Payments database.
A lion’s share of industry payments within oncology appears to be going to a small group of high-profile physicians, suggested a 2022 study published in JCO Oncology Practice. It found that just 1% of all US oncologists accounted for 37% of industry payments, with each receiving more than $100,000 a year.
Experts: Professional Societies Should Further Limit Industry Payments
While partnerships between drug companies and physicians are necessary and have often been positive, more than disclosure is needed to minimize the risk of patient harm, according to an editorial published in March in JCO Oncology Practice. In it, Nina Niu Sanford, MD, a radiation oncologist UT Southwestern Medical Center, Dallas, and Bishal Gyawali, MD, PhD, a medical oncologist at Queen’s University, Kingston, Ontario, Canada, argue that following a specific blueprint could help mitigate financial conflicts of interest.
For starters, Dr. Sanford and Dr. Gyawali contend in the editorial that the maximum general payment NCCN members are allowed to receive from industry should be $0, compared with a current bar of $20,000 from a single entity or $50,000 from all external entities combined. They also urge professional societies to follow the current policy of the American Society of Clinical Oncology and ban members serving in their leadership from receiving any general payments from the industry.
The authors further suggest that investigators of clinical trials should be barred from holding stock for the drug or product while it is under study and that editorialists should not have conflicts of interest with the company whose drug or product they are discussing.
Pharmaceutical money can harm patients in ways that are not always obvious, Dr. Gyawali said in an interview.
“It can dominate the conversation by removing critical viewpoints from these top people about certain drugs,” he said. “It’s not always about saying good things about the drug.”
For instance, he suggested, a doctor receiving payments from Pfizer might openly criticize perceived flaws in drugs from other companies but refrain from weighing in negatively on a Pfizer drug.
From 2016 to 2018, industry made general payments to more than 52,000 physicians for 137 unique cancer drugs, according to a separate 2021 study published in the Journal of Cancer Policy, for which Dr. Gyawali served as one of the coauthors.
The results suggest that pharmaceutical money affects the entire cancer system, not relatively few oncology leaders. The amounts and dollar values grew each year covered by the study, to nearly 466,000 payments totaling $98.5 million in 2018.
Adriane Fugh-Berman, MD, professor of pharmacology and physiology at Georgetown University, Washington, DC, and director of PharmedOut, a Georgetown-based project that advances evidence-based prescribing and educates healthcare professionals about pharmaceutical marketing practices, has called for a ban on industry gifts to physicians.
When a publication asks physicians to disclose relevant conflicts of interest, physicians may choose not to disclose, because they don’t feel that their conflicts are relevant, Dr. Fugh-Berman said. Drug and device makers have also grown sophisticated about how they work with physicians, she suggested. “It’s illegal to market a drug before it comes on the market, but it’s not illegal to market the disease,” said Dr. Fugh-Berman, noting that drugmakers often work on long timelines.
“The doctor is going around saying we don’t have good therapies. They’re not pushing a drug. And so they feel totally fine about it.”
Anecdotally, Dr. Fugh-Berman noted that, if anything, speaking fees and similar payments only improve doctors’ reputations. She said that’s especially true if the physicians are paid by multiple companies, on the supposed theory that their conflicts of interest cancel each other out.
“I’m not defending this,” added Dr. Fugh-Berman, observing that, at the end of the day, such conflicts may go against the interests of patients.
“Sometimes the best drugs are older, generic, cheap drugs, and if oncologists or other specialists are only choosing among the most promoted drugs, they’re not necessarily choosing the best drugs.”
Beyond any prestige, doctors have other possible nonfinancial incentives for receiving industry payments. “It’s the relationships,” Dr. Fugh-Berman said. “Companies are very good at offering friendship.”
Dr. El Bairi reported NCODA leadership and honoraria along with expert testimony through techspert.io. Dr. Ross reported that he is a deputy editor of JAMA but was not involved in decisions regarding acceptance of or the review of the manuscript he authored and discussed in this article. Dr. Ross also reported receiving grants from the Food and Drug Administration, Johnson & Johnson, the Medical Device Innovation Consortium, the Agency for Healthcare Research and Quality, and the National Heart, Lung, and Blood Institute. He was an expert witness in a qui tam suit alleging violations of the False Claims Act and Anti-Kickback Statute against Biogen that was settled in 2022. Dr. Mitchell reported no relevant financial relationships. Dr. Gyawali reported a consulting or advisory role with Vivio Health. Dr. Fugh-Berman reported being an expert witness for plaintiffs in complaints about drug and device marketing practices.
The findings reflect limited awareness in low-income countries about what scenarios constitute a conflict of interest, first author, Khalid El Bairi, MD, said during an interview. “There is a lack of training in ethics and integrity in medical schools [in countries in Africa], so people are not informed about conflicts of interest,” continued Dr. El Bairi, who presented the new research at the annual meeting of the American Society of Clinical Oncology. “There is also a lack of policies in universities and hospitals to guide clinicians about conflict of interest reporting.”

“Sometimes the best drugs are older, generic, cheap drugs, and if oncologists or other specialists are only choosing among the most promoted drugs, they’re not necessarily choosing the best drugs.”
Beyond any prestige, doctors have other possible nonfinancial incentives for receiving industry payments. “It’s the relationships,” Dr. Fugh-Berman said. “Companies are very good at offering friendship.”
Dr. El Bairi reported NCODA leadership and honoraria along with expert testimony through techspert.io. Dr. Ross reported that he is a deputy editor of JAMA but was not involved in decisions regarding acceptance of or the review of the manuscript he authored and discussed in this article. Dr. Ross also reported receiving grants from the Food and Drug Administration, Johnson & Johnson, the Medical Device Innovation Consortium, the Agency for Healthcare Research and Quality, and the National Heart, Lung, and Blood Institute. He was an expert witness in a qui tam suit alleging violations of the False Claims Act and Anti-Kickback Statute against Biogen that was settled in 2022. Dr. Mitchell reported no relevant financial relationships. Dr. Gyawali reported a consulting or advisory role with Vivio Health. Dr. Fugh-Berman reported being an expert witness for plaintiffs in complaints about drug and device marketing practices.
The findings reflect limited awareness in low-income countries about what scenarios constitute a conflict of interest, first author, Khalid El Bairi, MD, said during an interview. “There is a lack of training in ethics and integrity in medical schools [in countries in Africa], so people are not informed about conflicts of interest,” continued Dr. El Bairi, who presented the new research at the annual meeting of the American Society of Clinical Oncology. “There is also a lack of policies in universities and hospitals to guide clinicians about conflict of interest reporting.”
Overall, 58.5% of survey participants categorized honoraria as a conflict of interest that required disclosure, while 50% said the same of gifts from pharmaceutical representatives, and 44.5% identified travel grants for attending conferences as conflicts of interests. The report was published in JCO Global Oncology. Less often considered conflicts of interest were personal and institutional research funding, trips to conferences, consulting or advisory roles, food and beverages, expert testimony, and sample drugs provided by the pharmaceutical industry.
Just 24% of participants indicated that all of the listed items were deemed conflicts of interest. The survey — called Oncology Transparency Under Scrutiny and Tracking, or ONCOTRUST-1 — considered the perceptions of 200 oncologists, about 70% of whom practice in low- and middle-income countries.
What’s more, 37.5% of respondents identified fear of losing financial support as a reason not to report a conflict of interest. Still, 75% indicated that industry-sponsored speaking does not affect treatment decisions, and 60% said conflicts of interest do not impair objective appraisal of clinical trials.
Dr. El Bairi, a research associate in the department of medical oncology at Mohammed VI University Hospital, Oujda, Morocco, and his colleagues undertook the study in part because of an editorial published in The Lancet Oncology last year. First author Fidel Rubagumya, MD, a consultant oncologist and director of research at Rwanda Military Hospital, Kigali, and colleagues called for more research on the ties between oncologists and industry in Africa. The ONCOTRUST-1 findings set the stage for a planned follow-up study, which aims to compare views surrounding conflicts of interests between oncologists in different economic settings.
Open Payments Houses US Physicians’ Conflicts of Interest
To be sure, many authors of research published in major US journals are based outside of the United States. According to JAMA Network Open, 69% of submissions to the journal are from international authors. However, Dr. El Bairi also raised other potential signs of industry influence that he said need global discussion, such as the role of pharmaceutical companies in presentations of clinical trial findings at large cancer societies’ conferences, a shift toward progression-free survival as the endpoint in clinical cancer trials, and the rise of third-party writing assistance.
“There are two sides of the story,” Dr. El Bairi said. “The good side is that unfortunately, sometimes [industry money is] the only way for African oncologists to go abroad for training, to conferences for their continuous medical education. The bad is now we may harm patients, we might harm science by having conflicts of interest not reported.”
Unlike other countries, the United States has plentiful data on the scale of physicians’ financial conflicts of interest in the form of the Open Payments platform. Championed by Sen. Chuck Grassley (R-Iowa), the federal repository of payments to doctors and teaching hospitals by drug and medical device companies was established as part of the Affordable Care Act (ACA).
The health care reform law, which passed in 2010, requires pharmaceutical companies and medical device makers to report this information.
From 2013 to 2021, the pharmaceutical and medical device industry paid physicians $12.1 billion, according to a research letter published in JAMA in March of 2024 that reviewed Open Payments data.
Ranked by specialty, hematologists and oncologists received the fourth-largest amount of money in aggregate, the study shows. Their total of $825.8 million trailed only physicians in orthopedics ($1.36 billion), neurology and psychiatry ($1.32 billion) and cardiology ($1.29 billion). What’s more, this specialty had the biggest share of physicians taking industry money, with 74.2% of hematologists and oncologists receiving payments.
The payments from industry include fees for consulting services and speaking, as well as food and beverages, travel and lodging, education, gifts, grants, and honoraria.
Joseph S. Ross, MD, MHS, one of the JAMA study’s coauthors, said in an interview that the continued prevalence of such funding runs counter to the expectation behind the measure, which was that transparency would lead to physicians’ becoming less likely to accept a payment.
“We as a profession need to take a cold hard look in the mirror,” he said, referring to physicians in general.
Dr. Ross, professor of medicine at Yale University School of Medicine, New Haven, Connecticut, said he hopes that the profession will self-police, and that patients will make a bigger deal of the issue. Still, he acknowledged that “the vast majority” of patient advocacy groups, too, are funded by the pharmaceutical industry.
Exposing Industry Payments May Have Perverse Effect
A growing body of research explores the effect that physicians’ financial relationships with pharmaceutical companies can have on their prescribing practices. Indeed, oncologists taking industry payments seem to be more likely to prescribe nonrecommended and low-value drugs in some clinical settings, according to a study published in The BMJ last year.
That study’s first author, Aaron P. Mitchell, MD, a medical oncologist and assistant attending physician at Memorial Sloan Kettering Cancer Center, New York City, suggested in an interview that exposing industry payments to the sunlight may have had a perverse effect on physicians.
“There’s this idea of having license to do something,” Dr. Mitchell said, speaking broadly about human psychology rather than drawing on empirical data. “You might feel a little less bad about then prescribing more of that company’s drug, because the disclosure has already been done.”
The influence of pharmaceutical industry money on oncologists goes beyond what’s prescribed to which treatments get studied, approved, and recommended by guidelines, Dr. Mitchell said. He was also first author of a 2016 paper published in JAMA Oncology that found 86% of authors of the National Comprehensive Cancer Network guidelines had at least one conflict of interest reported on Open Systems in 2014.
Meanwhile, the fact that physicians’ payments from industry are a matter of public record on Open Systems has not guaranteed that doctors will disclose their conflicts of interest in other forums. A study published in JAMA earlier this year, for which Dr. Mitchell served as first author, found that almost one in three physicians endorsing drugs and devices on the social media platform X failed to disclose that the manufacturer paid them.
The lack of disclosure seems to extend beyond social media. A 2018 study published in JAMA Oncology found that 32% of oncologist authors of clinical drug trials for drugs approved over a 20-month period from 2016 to 2017 did not fully disclose payments from the trial sponsor when checked against the Open Payments database.
A lion’s share of industry payments within oncology appears to be going to a small group of high-profile physicians, suggested a 2022 study published in JCO Oncology Practice. It found that just 1% of all US oncologists accounted for 37% of industry payments, with each receiving more than $100,000 a year.
Experts: Professional Societies Should Further Limit Industry Payments
While partnerships between drug companies and physicians are necessary and have often been positive, more than disclosure is needed to minimize the risk of patient harm, according to an editorial published in March in JCO Oncology Practice. In it, Nina Niu Sanford, MD, a radiation oncologist UT Southwestern Medical Center, Dallas, and Bishal Gyawali, MD, PhD, a medical oncologist at Queen’s University, Kingston, Ontario, Canada, argue that following a specific blueprint could help mitigate financial conflicts of interest.
For starters, Dr. Sanford and Dr. Gyawali contend in the editorial that the maximum general payment NCCN members are allowed to receive from industry should be $0, compared with a current bar of $20,000 from a single entity or $50,000 from all external entities combined. They also urge professional societies to follow the current policy of the American Society of Clinical Oncology and ban members serving in their leadership from receiving any general payments from the industry.
The authors further suggest that investigators of clinical trials should be barred from holding stock for the drug or product while it is under study and that editorialists should not have conflicts of interest with the company whose drug or product they are discussing.
Pharmaceutical money can harm patients in ways that are not always obvious, Dr. Gyawali said in an interview.
“It can dominate the conversation by removing critical viewpoints from these top people about certain drugs,” he said. “It’s not always about saying good things about the drug.”
For instance, he suggested, a doctor receiving payments from Pfizer might openly criticize perceived flaws in drugs from other companies but refrain from weighing in negatively on a Pfizer drug.
From 2016 to 2018, industry made general payments to more than 52,000 physicians for 137 unique cancer drugs, according to a separate 2021 study published in the Journal of Cancer Policy, for which Dr. Gyawali served as one of the coauthors.
The results suggest that pharmaceutical money affects the entire cancer system, not relatively few oncology leaders. The amounts and dollar values grew each year covered by the study, to nearly 466,000 payments totaling $98.5 million in 2018.
Adriane Fugh-Berman, MD, professor of pharmacology and physiology at Georgetown University, Washington, DC, and director of PharmedOut, a Georgetown-based project that advances evidence-based prescribing and educates healthcare professionals about pharmaceutical marketing practices, has called for a ban on industry gifts to physicians.
When a publication asks physicians to disclose relevant conflicts of interest, physicians may choose not to disclose, because they don’t feel that their conflicts are relevant, Dr. Fugh-Berman said. Drug and device makers have also grown sophisticated about how they work with physicians, she suggested. “It’s illegal to market a drug before it comes on the market, but it’s not illegal to market the disease,” said Dr. Fugh-Berman, noting that drugmakers often work on long timelines.
“The doctor is going around saying we don’t have good therapies. They’re not pushing a drug. And so they feel totally fine about it.”
Anecdotally, Dr. Fugh-Berman noted that, if anything, speaking fees and similar payments only improve doctors’ reputations. She said that’s especially true if the physicians are paid by multiple companies, on the supposed theory that their conflicts of interest cancel each other out.
“I’m not defending this,” added Dr. Fugh-Berman, observing that, at the end of the day, such conflicts may go against the interests of patients.

FROM ASCO 2024
Should Cancer Trial Eligibility Become More Inclusive?
The study, published online in Clinical Cancer Research, highlighted the potential benefits of broadening eligibility criteria for clinical trials.
“It is well known that results in an ‘ideal’ population do not always translate to the real-world population,” senior author Hans Gelderblom, MD, chair of the Department of Medical Oncology at the Leiden University Medical Center, Leiden, the Netherlands, said in a press release. “Eligibility criteria are often too strict, and educated exemptions by experienced investigators can help individual patients, especially in a last-resort trial.”
Although experts have expressed interest in improving trial inclusivity, it’s unclear how doing so might impact treatment safety and efficacy.
In the Drug Rediscovery Protocol (DRUP), Dr. Gelderblom and colleagues examined the impact of broadening trial eligibility on patient outcomes. DRUP is an ongoing Dutch national, multicenter, pan-cancer, nonrandomized clinical trial in which patients are treated off-label with approved molecularly targeted or immunotherapies.
In the trial, 1019 patients with treatment-refractory disease were matched to one of the available study drugs based on their tumor molecular profile and enrolled in parallel cohorts. Cohorts were defined by tumor type, molecular profile, and study drug.
Among these patients, 82 patients — 8% of the cohort — were granted waivers to participate. Most waivers (45%) were granted as exceptions to general- or drug-related eligibility criteria, often because of out-of-range lab results. Other categories included treatment and testing exceptions, as well as out-of-window testing.
The researchers then compared safety and efficacy outcomes between the 82 participants granted waivers and the 937 who did not receive waivers.
Overall, Dr. Gelderblom’s team found that the rate of serious adverse events was similar between patients who received a waiver and those who did not: 39% vs 41%, respectively.
A relationship between waivers and serious adverse events was deemed “unlikely” for 86% of patients and “possible” for 14%. In two cases concerning a direct relationship, for instance, patients who received waivers for decreased hemoglobin levels developed anemia.
The rate of clinical benefit — defined as an objective response or stable disease for at least 16 weeks — was similar between the groups. Overall, 40% of patients who received a waiver (33 of 82) had a clinical benefit vs 33% of patients without a waiver (P = .43). Median overall survival for patients that received a waiver was also similar — 11 months in the waiver group and 8 months in the nonwaiver group (hazard ratio, 0.87; P = .33).
“Safety and clinical benefit were preserved in patients for whom a waiver was granted,” the authors concluded.
The study had several limitations. The diversity of cancer types, treatments, and reasons for protocol exemptions precluded subgroup analyses. In addition, because the decision to grant waivers depended in large part on the likelihood of clinical benefit, “it is possible that patients who received waivers were positively selected for clinical benefit compared with the general study population,” the authors wrote.
So, “although the clinical benefit rate of the patient group for whom a waiver was granted appears to be slightly higher, this difference might be explained by the selection process of the central study team, in which each waiver request was carefully considered, weighing the risks and potential benefits for the patient in question,” the authors explained.
Overall, “these findings advocate for a broader and more inclusive design when establishing novel trials, paving the way for a more effective and tailored application of cancer therapies in patients with advanced or refractory disease,” Dr. Gelderblom said.
Commenting on the study, Bishal Gyawali, MD, PhD, said that “relaxing eligibility criteria is important, and I support this. Trials should include patients that are more representative of the real-world, so that results are generalizable.”
However, “the paper overemphasized efficacy,” said Dr. Gyawali, from Queen’s University, Kingston, Ontario, Canada. The sample size of waiver-granted patients was small, plus “the clinical benefit rate is not a marker of efficacy.
“The response rate is somewhat better, but for a heterogeneous study with multiple targets and drugs, it is difficult to say much about treatment effects here,” Dr. Gyawali added. Overall, “we shouldn’t read too much into treatment benefits based on these numbers.”
Funding for the study was provided by the Stelvio for Life Foundation, the Dutch Cancer Society, Amgen, AstraZeneca, Bayer, Boehringer Ingelheim, Bristol Myers Squibb, pharma&, Eisai Co., Ipsen, Merck Sharp & Dohme, Novartis, Pfizer, and Roche. Dr. Gelderblom declared no conflicts of interest, and Dr. Gyawali declared no conflicts of interest related to his comment.

Weight Loss Drugs Cut Cancer Risk in Diabetes Patients
Recent research on popular weight loss drugs has uncovered surprising benefits beyond their intended use, like lowering the risk of fatal heart attacks. And now there may be another unforeseen advantage:
That’s according to a study published July 5 in JAMA Network Open where researchers studied glucagon-like peptide receptor agonists (known as GLP-1RAs), a class of drugs used to treat diabetes and obesity. Ozempic, Wegovy, Mounjaro, and Zepbound, which have become well-known recently because they are linked to rapid weight loss, contain GLP-1RAs.
For the study, they looked at electronic health records of 1.7 million patients who had type 2 diabetes, no prior diagnosis of obesity-related cancers, and had been prescribed GLP-1RAs, insulins, or metformin from March 2005 to November 2018.
The scientists found that compared to patients who took insulin, people who took GLP-1RAs had a “significant risk reduction” in 10 of 13 obesity-related cancers. Those 10 cancers were esophageal, colorectal, endometrial, gallbladder, kidney, liver, ovarian, and pancreatic cancers, as well as meningioma and multiple myeloma.
Compared with patients taking insulin, patients taking GLP-1RAs showed no statistically significant reduction in stomach cancer and no reduced risk of breast and thyroid cancers, the study said.
But the study found no decrease in cancer risk with GLP-1RAs compared with metformin.
While the study results suggest that these drugs may reduce the risk of certain obesity-related cancers better than insulins, more research is needed, they said.

Urticaria Linked to Higher Cancer Risk, Study Finds
TOPLINE:
which decreased to 6% in subsequent years, in a cohort study using Danish healthcare databases.
METHODOLOGY:
- Researchers conducted a retrospective cohort study using data from Danish healthcare registries and compared the incident cancer risk between patients with urticaria and the risk in the general population.
- They identified 87,507 patients (58% women) with a primary or secondary first-time hospital outpatient clinic, emergency room, or inpatient diagnosis of urticaria between 1980 and 2022, who were followed for a median of 10.1 years.
- Incident cancers, including nonmelanoma skin cancer, were identified using the Danish Cancer Registry and classified by the extent of spread at the time of diagnosis.
- This study computed the absolute cancer risk within the first year of an urticaria diagnosis and standardized incidence ratios (SIRs), with 95% CIs standardized to Danish national cancer rates.
TAKEAWAY:
- For the first year of follow-up, the absolute risk for all cancer types was 0.7%, and it was 29.5% for subsequent years. The overall SIR for all types of cancer was 1.09 (95% CI, 1.06-1.11), which was based on 7788 observed cancer cases compared with 7161 cases expected over the entire follow-up period.
- Within the first year of follow-up, 588 patients with urticaria were diagnosed with cancer, for an SIR of 1.49 (95% CI, 1.38-1.62) for all cancer types.
- After the first year, the SIR for all cancer sites decreased and stabilized at 1.06 (95% CI, 1.04-1.09), with 7200 observed cancer cases.
- The risk was highest for hematological cancers in the first year, particularly Hodgkin lymphoma (SIR, 5.35; 95% CI, 2.56-9.85).
IN PRACTICE:
“Our study suggests that urticaria may be a marker of occult cancer and that it is associated with a slightly increased long-term cancer risk,” the authors wrote.
SOURCE:
The study was led by Sissel B.T. Sørensen, departments of dermatology and rheumatology, Aarhus University Hospital, Aarhus, Denmark. It was published online on June 27, 2024, in the British Journal of Dermatology.
LIMITATIONS:
The study is limited by its observational design and reliance on registry data, which may be subject to misclassification or incomplete information. In addition, the study could not assess individual patient factors such as lifestyle or genetic predispositions that may influence cancer risk, and the results may not be generalizable to other populations. Finally, the exact biologic mechanisms linking urticaria and cancer remain unclear, warranting further investigation.

TOPLINE:
which decreased to 6% in subsequent years, in a cohort study using Danish healthcare databases.
METHODOLOGY:
- Researchers conducted a retrospective cohort study using data from Danish healthcare registries and compared the incident cancer risk between patients with urticaria and the risk in the general population.
- They identified 87,507 patients (58% women) with a primary or secondary first-time hospital outpatient clinic, emergency room, or inpatient diagnosis of urticaria between 1980 and 2022, who were followed for a median of 10.1 years.
- Incident cancers, including nonmelanoma skin cancer, were identified using the Danish Cancer Registry and classified by the extent of spread at the time of diagnosis.
- This study computed the absolute cancer risk within the first year of an urticaria diagnosis and standardized incidence ratios (SIRs), with 95% CIs standardized to Danish national cancer rates.
TAKEAWAY:
- For the first year of follow-up, the absolute risk for all cancer types was 0.7%, and it was 29.5% for subsequent years. The overall SIR for all types of cancer was 1.09 (95% CI, 1.06-1.11), which was based on 7788 observed cancer cases compared with 7161 cases expected over the entire follow-up period.
- Within the first year of follow-up, 588 patients with urticaria were diagnosed with cancer, for an SIR of 1.49 (95% CI, 1.38-1.62) for all cancer types.
- After the first year, the SIR for all cancer sites decreased and stabilized at 1.06 (95% CI, 1.04-1.09), with 7200 observed cancer cases.
- The risk was highest for hematological cancers in the first year, particularly Hodgkin lymphoma (SIR, 5.35; 95% CI, 2.56-9.85).
IN PRACTICE:
“Our study suggests that urticaria may be a marker of occult cancer and that it is associated with a slightly increased long-term cancer risk,” the authors wrote.
SOURCE:
The study was led by Sissel B.T. Sørensen, departments of dermatology and rheumatology, Aarhus University Hospital, Aarhus, Denmark. It was published online on June 27, 2024, in the British Journal of Dermatology.
LIMITATIONS:
The study is limited by its observational design and reliance on registry data, which may be subject to misclassification or incomplete information. In addition, the study could not assess individual patient factors such as lifestyle or genetic predispositions that may influence cancer risk, and the results may not be generalizable to other populations. Finally, the exact biologic mechanisms linking urticaria and cancer remain unclear, warranting further investigation.
