Three-quarters of oncologists participating in a recent global survey failed to identify one or more situations representing a conflict of interest, according to a new study.

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.

Patients starting first-line endocrine and CDK4/6 inhibition for advanced breast cancer show minimal additional cognitive decline beyond what they had already experienced from their neoadjuvant and adjuvant treatments, according to new results of the SONIA trial.

“Patients who are diagnosed with advanced breast cancer and start their first-line treatment already show cognitive impairments due to their previous treatments. And luckily, our results show that during first-line treatment for advanced breast cancer with endocrine therapy, with or without a CDK4/6 inhibitor, further cognitive decline is minimal,” lead investigator Maryse Luijendijk, said during her presentation at the annual meeting of the American Society of Clinical Oncology (ASCO).

“It is well known that cancer patients can experience cognitive problems, such as memory loss, problems with concentration or with planning, during or following their treatment,” explained Ms. Luijendijk, a PhD candidate in the department of Psychosocial Research and Epidemiology at the Netherlands Cancer Institute, in Amsterdam. “Much is known about the effects of chemotherapy or irradiation to the brain, but evidence into endocrine therapy is scarce, which is surprising because cognitive effects are biologically plausible.

“We know that estrogen plays an important role in neuronal functioning and that certain types of endocrine therapies are able to cross the blood-brain barrier, where they may interact with estrogen receptors distributed widely throughout the brain … We know that CDK4/6 inhibitors may either negatively affect cognitive function by increased fatigue due to cytokine release or by interrupting the cell cycle of healthy cells, or positively, as they have been associated with reduced inflammation and remyelination.”

Initial results of the SONIA trial, reported at ASCO last year, examined overall and progression-free survival in patients with HR-positive, HER2-negative metastatic breast cancer and no prior treatment for advanced disease. Findings for those who were randomized to treatment with nonsteroidal aromatase inhibition either with or without the addition of CDK4/6 inhibitors showed no between-group differences, explained Ms. Luijendijk.

The new results, described as being from the SONIA-EfFECT (Evaluation of cognitive functioning in patients with metastatic breast cancer treated with endocrine or combined therapy) trial, were based on the authors investigating cognitive functioning in the same cohort used in the SONIA trial plus a control group.

In SONIA-EfFECT, patients who participated in SONIA were asked to identify a female relative or friend without cancer to serve as a cancer-free control. Members of the 130-patient control group were matched for age, education, and computer use.

Participants in the SONIA trial and control group were asked to complete the Amsterdam Cognition Scan, an online neuropsychological test battery at baseline and again after 9 months of treatment. Of those patients from SONIA, 130 had received first-line treatment with aromatase inhibitors with CDK4/6 inhibition (Arm A) and 130 had received aromatase inhibitors without CDK4/6 inhibition (Arm B).

Baseline assessments for SONIA-EfFECT were completed for 260 patients from SONIA and the full 130-person control group. Follow-up assessments were completed for 119 members of the control group and 199 patients from the original SONIA trial (108 from Arm A, and 91 from Arm B). Patients from SONIA who switched to second-line treatment within 9 months were not retested.

Patients in both SONIA arms performed significantly worse than the controls on the domains of verbal memory, working memory, processing speed, executive function, and motor function. In both patient arms and the controls, standardized regression-based change scores showed limited decline in cognitive function over the 9-month interval. Minimal differences in cognitive change were observed between the patients treated with and without CDK4/6 inhibitors, and between patients and the controls, according to the abstract for SONIA-EfFECT, published in the program for the annual meeting of ASCO.

“At baseline, patients show worse cognitive function across all domains compared to the controls. And as expected, there were no differences between the two treatment arms,” Ms. Luijendijk explained. After 9 months of treatment, the testing showed limited further decline among patients, “and even some improvement on some tests,” with minimal differences between treatment arms “implying that cognitive function does not need to be an aspect when deciding on treatment.”

Eribulin seems to be an equally effective chemotherapy to pair with a dual HER2 blockade as taxane as first-line treatment for women with HER2-positive, locally advanced or metastatic breast cancer.

The results of this multicenter, randomized, open-label, parallel-group, phase 3 Japanese trial suggest that patients who cannot tolerate the standard taxane-based regimen have a new option for treatment.

“Our study is the first to show the non-inferiority of eribulin to a taxane, when used in combination with dual HER2 blockade as first-line treatment for this population,” lead author Toshinari Yamashita, MD, PhD, from the Kanagawa Cancer Center, in Kanagawa, Japan, said at the annual meeting of the American Society of Clinical Oncology.

“To our knowledge, noninferiority of eribulin to a taxane when used in combination with dual HER2 blockade has not been investigated,” Dr. Yamashita said.

“The combination of trastuzumab, pertuzumab, and taxane is a current standard first-line therapy for recurrent or metastatic HER2-positive breast cancer,” explained Dr. Yamashita. “However, because of taxane-induced toxicity, the development of less toxic but equally effective alternatives are needed.

“Because its efficacy is comparable to that of the current standard regimen, the combination of eribulin, trastuzumab, and pertuzumab is one of the options for first-line treatment of how to fight locally advanced or metastatic breast cancer,” he continued.
 

Study Results and Methods

The trial enrolled 446 patients, mean age 56 years, all of whom had locally advanced or metastatic breast cancer and no prior use of chemotherapy, excluding T-DM1. Patients who had received hormonal or HER2 therapy alone or the combination, as treatment for recurrence, were also eligible.

They were randomized 1:1 to receive a 21-day chemotherapy cycle of either (i) eribulin (1.4 mg/m² on days 1 and 8), or (ii) a taxane (docetaxel 75 mg/m² on day 1 or paclitaxel 80 mg/m² on days 1, 8 and 15), each being administered in combination with a dual HER2 blockade of trastuzumab plus pertuzumab.

Baseline characteristics of both groups were well balanced, with 257 (57.6%) having ER-positive disease, 292 (65.5%) visceral metastasis, and 263 (59%) with de novo stage 4 disease, explained Dr. Yamashita.

For the primary endpoint, the median progression-free survival (PFS) was 14 versus 12.9 months in the eribulin and taxane group, respectively (hazard ratio [HR] 0.95, P = .6817), confirming non-inferiority of the study regimen, he reported.

The clinical benefit rate was similar between the two groups, with an objective response rate of 76.8% in the eribulin group and 75.2% in the taxane group.

Median OS was 65.3 months in the taxane group, but has not been reached in the study group (HR 1.09).

In terms of side-effects, the incidence of treatment-emergent adverse events was similar between the eribulin and taxane groups (58.9% vs 59.2%, respectively, for grade 3 or higher).

“Skin-related adverse events (62.4% vs 40.6%), diarrhea (54.1% vs 36.6%), and edema (42.2% vs 8.5%) tend to be more common with taxane, whereas neutropenia (61.6% vs 30.7%) and peripheral neuropathy (61.2% vs 52.8%) tend to be more common with eribulin use,” he said.

Overall, “these results suggest that eribulin is less toxic chemotherapeutic partner for dual HER2 blockade and can be used for a longer,” he said.
 

Findings Are a ‘Clinical Pearl’

Harold Burstein, MD, PhD, a breast cancer expert at Dana-Farber Cancer Institute and professor at Harvard Medical School in Boston, described the findings as “a nice clinical pearl,” because some patients do not tolerate taxane therapy. “In such cases, you can substitute eribulin, which is usually tolerated without allergic hypersensitivity issues,” he said in an interview.

Eribulin has specific properties that “could make it a perfect candidate” as an adjunct to standard treatment regimens across different breast cancer subtypes, observed Wynne Wijaya, MD an oncology researcher at the University of Oxford, England, and Universitas Gadjah Mada, in Yogyakarta, Indonesia, in a recent review (World J Exp Med. 2024;14[2]:92558).

Dr. Wijaya, who was not involved in this study, said in an interview that the findings have important implications.

“This encouraging result adds eribulin as another option in the first line treatment regimen for patients with HER2-positive, locally advanced or metastatic breast cancer, especially in terms of side effects/toxicities,” she said. “As clinicians, we can offer to tailor the choice of therapy between eribulin versus taxane in the regimen based on [which side effects patients are better able to tolerate]. It would also be interesting and worthwhile to conduct similar trials in different types of populations to provide more robust evidence.”

Premenopausal patients with hormone receptor positive, HER2 negative (HR+/HER2-) metastatic breast cancer (mBC) continued to show consistent benefit when treated with CDK4/6 inhibition plus endocrine therapy compared with chemotherapy, according to updated survival outcomes of the Young-PEARL study.

“The combination of palbociclib plus exemestane plus leuprolide showed a consistent significant improvement in PFS [progression-free survival] compared to the capecitabine arm,” Yeon Hee Park, MD, PhD, from Samsung Medical Center, Sungkyunkwan University, Seoul, South Korea, reported at the annual meeting of the American Society of Clinical Oncology.
 

Study Methods and Results

Young-PEARL, a prospective, multicenter, open-label, randomized phase 2 study, included 184 patients, median age 44 years, who had relapsed or progressed during previous tamoxifen therapy, with one line of previous chemotherapy for mBC allowed. Patients were randomized to palbociclib plus endocrine therapy (oral palbociclib 125 mg per day for 21 days every 4 weeks, oral exemestane 25 mg per day for 28 days, plus leuprolide 3.75 mg subcutaneously every 4 weeks) or chemotherapy (oral capecitabine 1250 mg/m^2, twice daily for 2 weeks every 3 weeks).

Previously published initial results (Lancet Oncol. 2019 Dec;20[12]:1750-1759) for the primary endpoint showed a median PFS of 20.1 months in the palbociclib group versus 14.4 months in the capecitabine group, (hazard ratio [HR] 0.659, P = .0235) after median follow-up of 17 months.

Updated results showed this benefit was maintained after a median of 54 months, with a PFS of 19.5 months in the palbociclib arm, versus 14 months in capecitabine arm (HR 0.744, P = .0357), Dr. Park reported. However, this PFS benefit did not lead to an overall survival (OS) benefit, with median OS being similar: 54.8 versus 57.8 months in the palbociclib and capecitabine groups, respectively (HR = 1.02, P = .92).

To explore why PFS — but not OS — was better in the palbociclib arm, the researchers conducted a multivariate analysis which showed that going on to an additional CDK4/6 inhibitor treatment after the end of the study was as an independent variable favoring OS. Because more patients in the capecitabine arm received a post-study CDK4/6 inhibitor (49.3%) compared with in the palbociclib group (15%), this weighted the OS to the capecitabine arm, Dr. Park explained in an interview.

“In the capecitabine arm, excluding post-study CDK4/6 inhibitor use, the median OS was 38.8 months.” This was inferior to the 49 months OS seen in the palbociclib arm (P = .065), she said.

“As expected, hematologic toxicity was more common in the palbociclib arm compared with in the capecitabine arm,” Dr. Park said (92% vs 86%), with neutropenia topping the list [of all adverse events] (65.2% vs 27.9%, all grades). However, “most [adverse events] were not that serious,” Dr. Park said. Arthralgia was more common in the palbociclib arm (25% vs 7%), and diarrhea and hand-foot syndrome were more common in the capecitabine arm (15.2% vs 39.5% and 79.1% vs 2.2%).
 

Study Validates Endocrine Therapy + CDK4/6 Inhibitor as First Line

Commenting on Young-PEARL in an interview, Harold Burstein, MD, PhD, said, “The point of this study was to compare whether upfront chemotherapy would be better than upfront hormonal therapy for patients who had metastatic ER positive breast cancer.”

“This is the first study in probably 20 years that has compared these two approaches, and it validated that for the vast majority of patients with ER positive metastatic breast cancer, the appropriate first treatment is endocrine therapy with a CDK4/6 inhibitor,” continued Dr. Burstein, a breast cancer expert at Dana-Farber Cancer Institute, and professor at Harvard Medical School in Boston.

Premenopausal patients with hormone receptor positive, HER2 negative (HR+/HER2-) metastatic breast cancer (mBC) continued to show consistent benefit when treated with CDK4/6 inhibition plus endocrine therapy compared with chemotherapy, according to updated survival outcomes of the Young-PEARL study.

“The combination of palbociclib plus exemestane plus leuprolide showed a consistent significant improvement in PFS [progression-free survival] compared to the capecitabine arm,” Yeon Hee Park, MD, PhD, from Samsung Medical Center, Sungkyunkwan University, Seoul, South Korea, reported at the annual meeting of the American Society of Clinical Oncology.
 

Study Methods and Results

Young-PEARL, a prospective, multicenter, open-label, randomized phase 2 study, included 184 patients, median age 44 years, who had relapsed or progressed during previous tamoxifen therapy, with one line of previous chemotherapy for mBC allowed. Patients were randomized to palbociclib plus endocrine therapy (oral palbociclib 125 mg per day for 21 days every 4 weeks, oral exemestane 25 mg per day for 28 days, plus leuprolide 3.75 mg subcutaneously every 4 weeks) or chemotherapy (oral capecitabine 1250 mg/m^2, twice daily for 2 weeks every 3 weeks).

Previously published initial results (Lancet Oncol. 2019 Dec;20[12]:1750-1759) for the primary endpoint showed a median PFS of 20.1 months in the palbociclib group versus 14.4 months in the capecitabine group, (hazard ratio [HR] 0.659, P = .0235) after median follow-up of 17 months.

Updated results showed this benefit was maintained after a median of 54 months, with a PFS of 19.5 months in the palbociclib arm, versus 14 months in capecitabine arm (HR 0.744, P = .0357), Dr. Park reported. However, this PFS benefit did not lead to an overall survival (OS) benefit, with median OS being similar: 54.8 versus 57.8 months in the palbociclib and capecitabine groups, respectively (HR = 1.02, P = .92).

To explore why PFS — but not OS — was better in the palbociclib arm, the researchers conducted a multivariate analysis which showed that going on to an additional CDK4/6 inhibitor treatment after the end of the study was as an independent variable favoring OS. Because more patients in the capecitabine arm received a post-study CDK4/6 inhibitor (49.3%) compared with in the palbociclib group (15%), this weighted the OS to the capecitabine arm, Dr. Park explained in an interview.

“In the capecitabine arm, excluding post-study CDK4/6 inhibitor use, the median OS was 38.8 months.” This was inferior to the 49 months OS seen in the palbociclib arm (P = .065), she said.

“As expected, hematologic toxicity was more common in the palbociclib arm compared with in the capecitabine arm,” Dr. Park said (92% vs 86%), with neutropenia topping the list [of all adverse events] (65.2% vs 27.9%, all grades). However, “most [adverse events] were not that serious,” Dr. Park said. Arthralgia was more common in the palbociclib arm (25% vs 7%), and diarrhea and hand-foot syndrome were more common in the capecitabine arm (15.2% vs 39.5% and 79.1% vs 2.2%).

Patients with treatment-refractory cancers who did not meet eligibility criteria for a pan-cancer clinical trial but received waivers allowing them to participate had similar outcomes to patients who participated without waivers, a new analysis revealed.

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.

CHICAGO — The landscape of antibody-drug conjugates, or ADCs, continues to grow more crowded in metastatic breast cancer. Indications are expanding, new agents are emerging, combinations with other drug classes are being tested, and many patients with this disease are now receiving more than one ADC.

ADCs use antibodies to bind to the surface proteins of cancer cells to deliver a potent payload of cytotoxic chemotherapy. Three are approved for use in pretreated patients with metastatic breast cancer: sacituzumab govitecan, or SG, for patients with triple-negative disease; trastuzumab deruxtecan, or T-DXd, for patients with HER2-positive and HER2-low disease; and trastuzumab emtansine, or T-DM1, for patients with HER2-positive disease. A fourth agent, datopotamab deruxtecan, or Dato-DXd, is being assessed by the US Food and Drug Administration (FDA) for use in pretreated HR-positive, HER2-negative patients, and others, including sacituzumab tirumotecan, are being tested in clinical trials.At the annual meeting of the American Society of Clinical Oncology, T-DXd (Enhertu, AstraZeneca) showed better progression free survival than chemotherapy in people with HR-positive, HER 2-low metastatic breast cancers. These findings, from the DESTINY Breast-06 trial, were among the most talked-about at ASCO, and are likely to change clinical practice (J Clin Oncol. 2024;42[suppl 17; abstr LBA1000]).

But other ADC results presented at ASCO showed that there is still much to be worked out about the timing and sequencing of these agents, as well as their synergy with other drug classes, in metastatic breast cancer.
 

An ADC gets its first test, and falls short

Antonio Giordano, MD, PhD, of the Dana-Farber Cancer Institute in Boston, presented findings from an open-label phase 2 study of the ADC enfortumab vedotin (EV), an agent currently approved for use in advanced or metastatic urothelial cancer, at ASCO. This study included two cohorts of previously treated metastatic breast cancer patients: one with triple-negative disease (n = 42) and the other with HR-positive HER2-negative (n = 45).

Dr. Giordano and his colleagues’ study is the first to look at this ADC in breast cancer. EV’s antibody targets the cell adhesion molecule Nectin-4.

The researchers found that though EV demonstrated anti-tumor activity in both cohorts — with 19% of the triple-negative patients and 15.6% of the HR-positive/HER2-negative patients responding — the results did not meet the prespecified response thresholds for either cohort. (J Clin Oncol. 2024;42[suppl 16; abstr 1005]).

In an interview, Dr. Giordano said that studies in urothelial cancer had shown better response to EV associated with more expression of Nectin-4, but this study did not see such clear associations between expression and response. While there is no question that Nectin-4 is highly expressed in breast cancer and therefore a viable target, he said, “it may need to be looked at a little more deeply.”

It could also be the case, Dr. Giordano said, that the effect of EV’s payload may have been less robust in participants who had been previously treated with taxane chemotherapy, as nearly all patients in the two cohorts were.

“Taxanes are microtubule disruptors. And with this drug we had a payload with pretty much the same mechanism of action,” Dr. Giordano said. Ideally, he said, he would like to test the agent in a first-line setting, possibly in combination with an immunotherapy agent.

The timing of ADCs is as important as their targets and their payloads — and something that investigators are still struggling to figure out, he said.

A third of the patients in the triple-negative cohort of his study had been previously treated with SG, and a handful of individuals with T-Dxd, he noted.

“We’re in the middle of an ADC revolution,” he said. “It’s really key to figure out the best sequencing for a patient and if it’s actually worth it to do it. Very often we see patients respond best to the first ADC. But sometimes we see patients that do not respond to the first ADC and then they respond to the second one. It’s not very frequent, but it happens.”
 

Hint of Benefit from Adding Immunotherapy to SG

In a separate presentation at ASCO, Ana C. Garrido-Castro, MD, also of the Dana-Farber Cancer Institute, presented results from the SACI-IO HR+ trial, a randomized phase 2 study of SG (Trodelvy, Gilead) with and without pembrolizumab (Keytruda, Merck) in 104 patients with metastatic HR-positive/HER2-negative breast cancer who received prior endocrine therapy and up to one chemotherapy regimen for advanced disease. SACI-IO HR+ is the first randomized trial to report the efficacy of a topoisomerase I-inhibitor ADC with an immune checkpoint inhibitor for the treatment of breast cancer.

The addition of the immune checkpoint inhibitor did not result in a significant improvement in median progression-free survival in the overall population, Dr. Garrido-Castro reported. Median PFS was 8.1 vs 6.2 months with the combination of SG plus pembrolizumab or sacituzumab govitecan alone, respectively. At a median follow-up of 12.5 months, there was also no significant difference seen in median overall survival (OS): 18.5 vs 18.0 months.

About 40% of participants were found to have PD-L1-positive tumors and, among this subgroup, there was a 4.4-month increase in median PFS and 6.0-month increase in median OS with the addition of pembrolizumab to SG, although this did not reach statistical significance. (J Clin Oncol. 2024;42[suppl 17; abstr LBA1004]).

“While the study did not demonstrate a statistically significant benefit with the addition of the immune checkpoint inhibitor to the ADC, there is an interesting signal for potential synergistic activity between the two agents, particularly in those patients with PD-L1 positive tumors,” Dr. Garrido-Castro said in an interview. She noted that the sample sizes for the PD-L1 subgroup were relatively small, and overall survival data are not yet mature.

A separate phase 3 study is looking at the experimental ADC called sacituzumab tirumotecan with and without pembrolizumab compared with chemotherapy in patients with metastatic HR-positive, HER2-negative breast cancer who have received prior endocrine therapy and no prior chemotherapy for metastatic disease, she said.

Similar to SG, sacituzumab tirumotecan is a TROP2-directed ADC with a topoisomerase I-inhibitor payload. With an estimated enrollment of 1,200 patients, this trial may help shed light on whether adding the immune checkpoint inhibitor to the topoisomerase I-inhibitor TROP2-directed ADC improves outcomes in the subgroup of patients with PD-L1 positive tumors, Dr. Garrido-Castro said.
 

Unlocking the Order and Timing of ADCs

Dr. Garrido-Castro is also leading a study that will evaluate the sequential use of ADCs in metastatic breast cancer. That trial, to be called TRADE-DXd, will enroll patients with HER2-low metastatic breast cancer who have received up to one prior line of chemotherapy and no previous topoisomerase I-inhibitors. Participants will receive either T-DXd or Dato-DXd as the first ADC, and then switch to the other ADC (Dato-DXd or T-DXd, respectively) at the time of progression, thus switching the target of the ADC from HER2 to TROP2 or vice versa.

“In real-world practice now, there are patients who receive sequential ADCs, because they are candidates for both,” Dr. Garrido-Castro explained. However, more robust data are needed to refine the selection of the initial antibody drug conjugate and to determine who is more likely to benefit from a second — or maybe even third — ADC.

“One potential mechanism of resistance to antibody drug conjugates is the downregulation of the target of the antibody drug conjugate,” Dr. Garrido-Castro said. “Thus, an important question is, if you modify the target of the ADC, is it possible to overcome that mechanism of resistance?” Another possible mechanism of resistance is to the chemotherapy payload of the ADCs, she said.

Dr. Garrido-Castro’s study will collect tumor samples and blood samples for the purposes of planned correlative analyses to try to better understand the mechanisms that drive response and resistance to these agents.

Dr. Giordano commented that Dr. Garrido-Castro’s study was likely to result in a much better understanding of ADCs and how to use them strategically.

At Dana-Farber, “we collect a lot of samples of patients receiving ADCs. And we are trying to do all kinds of work on circulating tumor DNA, immunohistochemistry expression, and protein expression,” he said. “We are trying to figure out how ADCs really work, and why they stop working.”

CHICAGO — The landscape of antibody-drug conjugates, or ADCs, continues to grow more crowded in metastatic breast cancer. Indications are expanding, new agents are emerging, combinations with other drug classes are being tested, and many patients with this disease are now receiving more than one ADC.

ADCs use antibodies to bind to the surface proteins of cancer cells to deliver a potent payload of cytotoxic chemotherapy. Three are approved for use in pretreated patients with metastatic breast cancer: sacituzumab govitecan, or SG, for patients with triple-negative disease; trastuzumab deruxtecan, or T-DXd, for patients with HER2-positive and HER2-low disease; and trastuzumab emtansine, or T-DM1, for patients with HER2-positive disease. A fourth agent, datopotamab deruxtecan, or Dato-DXd, is being assessed by the US Food and Drug Administration (FDA) for use in pretreated HR-positive, HER2-negative patients, and others, including sacituzumab tirumotecan, are being tested in clinical trials.At the annual meeting of the American Society of Clinical Oncology, T-DXd (Enhertu, AstraZeneca) showed better progression free survival than chemotherapy in people with HR-positive, HER 2-low metastatic breast cancers. These findings, from the DESTINY Breast-06 trial, were among the most talked-about at ASCO, and are likely to change clinical practice (J Clin Oncol. 2024;42[suppl 17; abstr LBA1000]).

But other ADC results presented at ASCO showed that there is still much to be worked out about the timing and sequencing of these agents, as well as their synergy with other drug classes, in metastatic breast cancer.
 

An ADC gets its first test, and falls short

Antonio Giordano, MD, PhD, of the Dana-Farber Cancer Institute in Boston, presented findings from an open-label phase 2 study of the ADC enfortumab vedotin (EV), an agent currently approved for use in advanced or metastatic urothelial cancer, at ASCO. This study included two cohorts of previously treated metastatic breast cancer patients: one with triple-negative disease (n = 42) and the other with HR-positive HER2-negative (n = 45).

Dr. Giordano and his colleagues’ study is the first to look at this ADC in breast cancer. EV’s antibody targets the cell adhesion molecule Nectin-4.

The researchers found that though EV demonstrated anti-tumor activity in both cohorts — with 19% of the triple-negative patients and 15.6% of the HR-positive/HER2-negative patients responding — the results did not meet the prespecified response thresholds for either cohort. (J Clin Oncol. 2024;42[suppl 16; abstr 1005]).

In an interview, Dr. Giordano said that studies in urothelial cancer had shown better response to EV associated with more expression of Nectin-4, but this study did not see such clear associations between expression and response. While there is no question that Nectin-4 is highly expressed in breast cancer and therefore a viable target, he said, “it may need to be looked at a little more deeply.”

It could also be the case, Dr. Giordano said, that the effect of EV’s payload may have been less robust in participants who had been previously treated with taxane chemotherapy, as nearly all patients in the two cohorts were.

“Taxanes are microtubule disruptors. And with this drug we had a payload with pretty much the same mechanism of action,” Dr. Giordano said. Ideally, he said, he would like to test the agent in a first-line setting, possibly in combination with an immunotherapy agent.

The timing of ADCs is as important as their targets and their payloads — and something that investigators are still struggling to figure out, he said.

A third of the patients in the triple-negative cohort of his study had been previously treated with SG, and a handful of individuals with T-Dxd, he noted.

“We’re in the middle of an ADC revolution,” he said. “It’s really key to figure out the best sequencing for a patient and if it’s actually worth it to do it. Very often we see patients respond best to the first ADC. But sometimes we see patients that do not respond to the first ADC and then they respond to the second one. It’s not very frequent, but it happens.”
 

Hint of Benefit from Adding Immunotherapy to SG

In a separate presentation at ASCO, Ana C. Garrido-Castro, MD, also of the Dana-Farber Cancer Institute, presented results from the SACI-IO HR+ trial, a randomized phase 2 study of SG (Trodelvy, Gilead) with and without pembrolizumab (Keytruda, Merck) in 104 patients with metastatic HR-positive/HER2-negative breast cancer who received prior endocrine therapy and up to one chemotherapy regimen for advanced disease. SACI-IO HR+ is the first randomized trial to report the efficacy of a topoisomerase I-inhibitor ADC with an immune checkpoint inhibitor for the treatment of breast cancer.

The addition of the immune checkpoint inhibitor did not result in a significant improvement in median progression-free survival in the overall population, Dr. Garrido-Castro reported. Median PFS was 8.1 vs 6.2 months with the combination of SG plus pembrolizumab or sacituzumab govitecan alone, respectively. At a median follow-up of 12.5 months, there was also no significant difference seen in median overall survival (OS): 18.5 vs 18.0 months.

About 40% of participants were found to have PD-L1-positive tumors and, among this subgroup, there was a 4.4-month increase in median PFS and 6.0-month increase in median OS with the addition of pembrolizumab to SG, although this did not reach statistical significance. (J Clin Oncol. 2024;42[suppl 17; abstr LBA1004]).

“While the study did not demonstrate a statistically significant benefit with the addition of the immune checkpoint inhibitor to the ADC, there is an interesting signal for potential synergistic activity between the two agents, particularly in those patients with PD-L1 positive tumors,” Dr. Garrido-Castro said in an interview. She noted that the sample sizes for the PD-L1 subgroup were relatively small, and overall survival data are not yet mature.

A separate phase 3 study is looking at the experimental ADC called sacituzumab tirumotecan with and without pembrolizumab compared with chemotherapy in patients with metastatic HR-positive, HER2-negative breast cancer who have received prior endocrine therapy and no prior chemotherapy for metastatic disease, she said.

Similar to SG, sacituzumab tirumotecan is a TROP2-directed ADC with a topoisomerase I-inhibitor payload. With an estimated enrollment of 1,200 patients, this trial may help shed light on whether adding the immune checkpoint inhibitor to the topoisomerase I-inhibitor TROP2-directed ADC improves outcomes in the subgroup of patients with PD-L1 positive tumors, Dr. Garrido-Castro said.
 

Unlocking the Order and Timing of ADCs

Dr. Garrido-Castro is also leading a study that will evaluate the sequential use of ADCs in metastatic breast cancer. That trial, to be called TRADE-DXd, will enroll patients with HER2-low metastatic breast cancer who have received up to one prior line of chemotherapy and no previous topoisomerase I-inhibitors. Participants will receive either T-DXd or Dato-DXd as the first ADC, and then switch to the other ADC (Dato-DXd or T-DXd, respectively) at the time of progression, thus switching the target of the ADC from HER2 to TROP2 or vice versa.

“In real-world practice now, there are patients who receive sequential ADCs, because they are candidates for both,” Dr. Garrido-Castro explained. However, more robust data are needed to refine the selection of the initial antibody drug conjugate and to determine who is more likely to benefit from a second — or maybe even third — ADC.

“One potential mechanism of resistance to antibody drug conjugates is the downregulation of the target of the antibody drug conjugate,” Dr. Garrido-Castro said. “Thus, an important question is, if you modify the target of the ADC, is it possible to overcome that mechanism of resistance?” Another possible mechanism of resistance is to the chemotherapy payload of the ADCs, she said.

Dr. Garrido-Castro’s study will collect tumor samples and blood samples for the purposes of planned correlative analyses to try to better understand the mechanisms that drive response and resistance to these agents.

Dr. Giordano commented that Dr. Garrido-Castro’s study was likely to result in a much better understanding of ADCs and how to use them strategically.

At Dana-Farber, “we collect a lot of samples of patients receiving ADCs. And we are trying to do all kinds of work on circulating tumor DNA, immunohistochemistry expression, and protein expression,” he said. “We are trying to figure out how ADCs really work, and why they stop working.”

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: People with type 2 diabetes who took these drugs had a lower risk of having 10 out of 13 obesity-related cancers, compared to those who used insulin therapy.

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.

TOPLINE:

Compared with the general population, patients with urticaria had a 49% higher risk of developing cancer in the first year following diagnosis, 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.

DISCLOSURES:

The study did not receive any funding. The authors reported that they had no relevant conflicts of interest.

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.

DISCLOSURES:

The study did not receive any funding. The authors reported that they had no relevant conflicts of interest.

On any given day, oncologist Mark Lewis, MD, feels like he’s seesawing between two eras of technology. 

One minute, he’s working on sequencing a tumor genome. The next, he’s sifting through pages of disorganized data from a device that has been around for decades: the fax machine. 

“If two doctors’ offices aren’t on the same electronic medical record, one of the main ways to transfer records is still by fax,” said Dr. Lewis, director of gastrointestinal oncology at Intermountain Healthcare in Murray, Utah. “I can go from cutting-edge innovation to relying on, at best, 1980s information technology. It just boggles my mind.”

Dr. Lewis, who has posted about his frustration with fax machines, is far from alone. Oncologists are among the many specialists across the country at the mercy of telecopiers. 

According to a 2021 report by the Office of the National Coordinator for Health Information Technology, fax and mail continue to be the most common methods for hospitals and health systems to exchange care record summaries. In 2019, nearly 8 in 10 hospitals used mail or fax to send and receive health information, the report found. 

Fax machines are still commonplace across the healthcare spectrum, said Robert Havasy, MS, senior director for informatics strategy at the Healthcare Information and Management Systems Society (HIMSS). Inertia, cost, and more pressing priorities for hospitals and medical institutions contribute to the technology sticking around, he explained. 

“Post-COVID, my guess is we’re still at over 50% of healthcare practices using fax for some reason, on a daily basis,” Mr. Havasy said in an interview. “A lot of hospitals just don’t have the time, the money, or the staff to fix that problem because there’s always something a little higher up the priority chain they need to focus on.” 

If, for instance, “you’re going to do a process redesign to reduce hospital total acquired infections, your fax machine replacement might be 10th or 12th on the list. It just never gets up to 1 or 2 because it’s ‘not that much of a problem,’ ” he added.

Or is it?

Administrators may not view fax machines as a top concern, but clinicians who deal with the machines daily see it differently. 

“What worries me is we’re taking records out of an electronic storehouse [and] converting them to a paper medium,” Dr. Lewis said. “And then we are scanning into another electronic storehouse. The more steps, the more can be lost.”

And when information is lost, patient care can be compromised. 

Slower Workflows, Care Concerns

Although there are no published data on fax machine use in oncology specifically, this outdated technology does come into play in a variety of ways along the cancer care continuum. 

Radiation oncologist David R. Penberthy, MD, said patients often seek his cancer center’s expertise for second opinions, and that requires collecting patient records from many different practices. 

“Ideally, it would come electronically, but sometimes it does come by fax,” said Dr. Penberthy, program director of radiation oncology at the University of Virginia School of Medicine in Charlottesville. “The quality of the fax is not always the best. Sometimes it’s literally a fax of a fax. You’re reading something that’s very difficult to read.” 

Orders for new tests are also typically sent and received via fax temporarily while IT teams work to integrate them into the electronic health record (EHR), Dr. Penberthy said. 

Insurers and third-party laboratories often send test results back by fax as well.

“Even if I haven’t actually sent my patient out of our institution, this crucial result may only be entered back into the record as a scanned document from a fax, which is not great because it can get lost in the other results that are reported electronically,” Dr. Lewis said. The risk here is that an ordering physician won’t see these results, which can lead to delayed or overlooked care for patients, he explained.

“To me, it’s like a blind spot,” Dr. Lewis said. “Every time we use a fax, I see it actually as an opportunity for oversight and missed opportunity to collect data.”

Dr. Penberthy said faxing can slow things down at his practice, particularly if he faxes a document to another office but receives no confirmation and has to track down what happened. 

As for cybersecurity, data that are in transit during faxing are generally considered secure and compliant with the Health Insurance Portability and Accountability Act (HIPAA), said Mr. Havasy of HIMSS. However, the Privacy Rule also requires that data remain secure while at rest, which isn’t always possible, he added. 

“That’s where faxes fall down, because generally fax machines are in public, if you will, or open areas in a hospital,” he said. “They just sit on a desk. I don’t know that the next nurse who comes up and looks through that stack was the nurse who was treating the patient.” 

Important decisions or results can also be missed when sent by fax, creating headaches for physicians and care problems for patients. 

Dr. Lewis recently experienced an insurance-related fax mishap over Memorial Day weekend. He believed his patient had access to the antinausea medication he had prescribed. When Dr. Lewis happened to check the fax machine over the weekend, he found a coverage denial for the medication from the insurer but, at that point, had no recourse to appeal because it was a long holiday weekend. 

“Had the denial been sent by an electronic means that was quicker and more readily available, it would have been possible to appeal before the holiday weekend,” he said. 

Hematologist Aaron Goodman, MD, encountered a similar problem after an insurer denied coverage of an expensive cancer drug for a patient and faxed over its reason for the denial. Dr. Goodman was not directly notified that the information arrived and didn’t learn about the denial for a week, he said. 

“There’s no ‘ding’ in my inbox if something is faxed over and scanned,” said Dr. Goodman, associate professor of medicine at UC San Diego Health. “Once I realized it was denied, I was able to rectify it, but it wasted a week of a patient not getting a drug that I felt would be beneficial for them.”

Broader Health Policy Impacts

The use of outdated technology, such as fax machines, also creates ripple effects that burden the health system, health policy experts say. 

Duplicate testing and unnecessary care are top impacts, said Julia Adler-Milstein, PhD, professor of medicine and chief of the division of clinical informatics and digital transformation at the University of California, San Francisco.

Studies show that 20%-30% of the $65 billion spent annually on lab tests is used on unnecessary duplicate tests, and another estimated $30 billion is spent each year on unnecessary duplicate medical imaging. These duplicate tests may be mitigated if hospitals adopt certified EHR technology, research shows.

Still, without EHR interoperability between institutions, new providers may be unaware that tests or past labs for patients exist, leading to repeat tests, said Dr. Adler-Milstein, who researches health IT policy with a focus on EHRs. Patients can sometimes fill in the gaps, but not always. 

“Fax machines only help close information gaps if the clinician is aware of where to seek out the information and there is someone at the other organization to locate and transmit the information in a timely manner,” Dr. Adler-Milstein said. 

Old technology and poor interoperability also greatly affect data collection for disease surveillance and monitoring, said Janet Hamilton, MPH, executive director for the Council of State and Territorial Epidemiologists. This issue was keenly demonstrated during the pandemic, Ms. Hamilton said. 

“It was tragic, quite honestly,” she said. “There was such an immense amount of data that needed to be moved quickly, and that’s when computers are at their best.”

But, she said, “we didn’t have the level of systems in place to do it well.”

Specifically, the lack of electronic case reporting in place during the pandemic — where diagnoses are documented in the record and then immediately sent to the public health system — led to reports that were delayed, not made, or had missing or incomplete information, such as patients’ race and ethnicity or other health conditions, Ms. Hamilton said. 

Incomplete or missing data hampered the ability of public health officials and researchers to understand how the virus might affect different patients.

“If you had a chronic condition like cancer, you were less likely to have a positive outcome with COVID,” Ms. Hamilton said. “But because electronic case reporting was not in place, we didn’t get some of those additional pieces of information. We didn’t have people’s underlying oncology status to then say, ‘Here are individuals with these types of characteristics, and these are the things that happen if they also have a cancer.’” 

Slow, but Steady, Improvements

Efforts at the state and federal levels have targeted improved health information exchange, but progress takes time, Dr. Adler-Milstein said.

Most states have some form of health information exchange, such as statewide exchanges, regional health information organizations, or clinical data registries. Maryland is often held up as a notable example for its health information exchange, Dr. Adler-Milstein noted.

According to Maryland law, all hospitals under the jurisdiction of the Maryland Health Care Commission are required to electronically connect to the state-designated health information exchange. In 2012, Maryland became the first state to connect all its 46 acute care hospitals in the sharing of real-time data. 

The Health Information Technology for Economic and Clinical Health (HITECH) Act provided federal-enhanced Medicaid matching funds to states through 2021 to support efforts to advance electronic exchange. Nearly all states used these funds, and most have identified other sources to sustain the efforts, according to a recent US Government Accountability Office (GAO) report. However, GAO found that small and rural providers are less likely to have the financial and technological resources to participate in or maintain electronic exchange capabilities.

Nationally, several recent initiatives have targeted health data interoperability, including for cancer care. The Centers for Disease Control and Prevention’s Data Modernization Initiative is a multiyear, multi–billion-dollar effort to improve data sharing across the federal and state public health landscape. 

Meanwhile, in March 2024, the Biden-Harris administration launched United States Core Data for Interoperability Plus Cancer. The program will define a recommended minimum set of cancer-related data to be included in a patient’s EHR to enhance data exchange for research and clinical care. 

EHR vendors are also key to improving the landscape, said Dr. Adler-Milstein. Vendors such as Epic have developed strong sharing capabilities for transmitting health information from site to site, but of course, that only helps if providers have Epic, she said. 

“That’s where these national frameworks should help, because we don’t want it to break down by what EHR vendor you have,” she said. “It’s a patchwork. You can go to some places and hear success stories because they have Epic or a state health information exchange, but it’s very heterogeneous. In some places, they have nothing and are using a fax machine.”

Mr. Havasy believes fax machines will ultimately go extinct, particularly as a younger, more digitally savvy generation enters the healthcare workforce. He also foresees that the growing use of artificial intelligence will help eradicate the outdated technology. 

But, Ms. Hamilton noted, “unless we have consistent, ongoing, sustained funding, it is very hard to move off [an older] technology that can work. That’s one of the biggest barriers.” 

“Public health is about protecting the lives of every single person everywhere,” Ms. Hamilton said, “but when we don’t have the data that comes into the system, we can’t achieve our mission.”

Results from the latest survey by the National Comprehensive Cancer Network (NCCN) showed that numerous critical systemic anticancer therapies, primarily generic drugs, are currently in shortage.

Nearly 90% of the 28 NCCN member centers who responded to the survey, conducted between May 28 and June 11, said they were experiencing a shortage of at least one drug.

“Many drugs that are currently in shortage form the backbones of effective multiagent regimens across both curative and palliative treatment settings,” NCCN’s CEO Crystal S. Denlinger, MD, said in an interview.

The good news is that carboplatin and cisplatin shortages have fallen dramatically since 2023. At the peak of the shortage in 2023, 93% of centers surveyed reported experiencing a shortage of carboplatin and 70% were experiencing a shortage of cisplatin, whereas in 2024, only 11% reported a carboplatin shortage and 7% reported a cisplatin shortage.

“Thankfully, the shortages for carboplatin and cisplatin are mostly resolved at this time,” Dr. Denlinger said.

However, all three NCCN surveys conducted in the past year, including the most recent one, have found shortages of various chemotherapies and supportive care medications, which suggests this is an ongoing issue affecting a significant spectrum of generic drugs.

“The acute crisis associated with the shortage of carboplatin and cisplatin was a singular event that brought the issue into the national spotlight,” but it’s “important to note that the current broad drug shortages found on this survey are not new,” said Dr. Denlinger.

In the latest survey, 89% of NCCN centers continue to report shortages of one or more drugs, and 75% said they are experiencing shortages of two or more drugs.

Overall, 57% of centers are short on vinblastine, 46% are short on etoposide, and 43% are short on topotecan. Other common chemotherapy and supportive care agents in short supply include dacarbazine (18% of centers) as well as 5-fluorouracil (5-FU) and methotrexate (14% of centers).

In 2023, however, shortages of methotrexate and 5-FU were worse, with 67% of centers reporting shortages of methotrexate and 26% of 5-FU.

In the current survey, 75% of NCCN centers also noted they were aware of drug shortages within community practices in their area, and more than one in four centers reported treatment delays requiring additional prior authorization.

Cancer drug shortages impact not only routine treatments but also clinical trials. The recent survey found that 43% of respondents said drug shortages disrupted clinical trials at their center. The biggest issues centers flagged included greater administrative burdens, lower patient enrollment, and fewer open trials.

How are centers dealing with ongoing supply issues?

Top mitigation strategies include reducing waste, limiting use of current stock, and adjusting the timing and dosage within evidence-based ranges.

“The current situation underscores the need for sustainable, long-term solutions that ensure a stable supply of high-quality cancer medications,” Alyssa Schatz, MSW, NCCN senior director of policy and advocacy, said in a news release.

Three-quarters (75%) of survey respondents said they would like to see economic incentives put in place to encourage the high-quality manufacturing of medications, especially generic versions that are often in short supply. Nearly two-thirds (64%) cited a need for a broader buffer stock payment, and the same percentage would like to see more information on user experiences with various generic suppliers to help hospitals contract with those engaging in high-quality practices.

The NCCN also continues to work with federal regulators, agencies, and lawmakers to implement long-term solutions to cancer drug shortages.

“The federal government has a key role to play in addressing this issue,” Ms. Schatz said. “Establishing economic incentives, such as tax breaks or manufacturing grants for generic drugmakers, will help support a robust and resilient supply chain — ultimately safeguarding care for people with cancer across the country.”
