Neurofilament Light Chain Detects Early Chemotherapy-Related Neurotoxicity
Investigators found Nfl levels increased in cancer patients following a first infusion of the medication paclitaxel and corresponded to neuropathy severity 6-12 months post-treatment, suggesting the blood protein may provide an early CIPN biomarker.
“Nfl after a single cycle could detect axonal degeneration,” said lead investigator Masarra Joda, a researcher and PhD candidate at the University of Sydney in Australia. She added that “quantification of Nfl may provide a clinically useful marker of emerging neurotoxicity in patients vulnerable to CIPN.”
The findings were presented at the Peripheral Nerve Society (PNS) 2024 annual meeting.
Common, Burdensome Side Effect
A common side effect of chemotherapy, CIPN manifests as sensory neuropathy and causes degeneration of the peripheral axons. A protein biomarker of axonal degeneration, Nfl has previously been investigated as a way of identifying patients at risk of CIPN.
The goal of the current study was to identify the potential link between Nfl with neurophysiological markers of axon degeneration in patients receiving the neurotoxin chemotherapy paclitaxel.
The study included 93 cancer patients. All were assessed at the beginning, middle, and end of treatment. CIPN was assessed using blood samples of Nfl and the Total Neuropathy Score (TNS), the Common Terminology Criteria for Adverse Events (CTCAE) neuropathy scale, and patient-reported measures using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire–Chemotherapy-Induced Peripheral Neuropathy Module (EORTC-CIPN20).
Axonal degeneration was measured with neurophysiological tests including sural nerve compound sensory action potential (CSAP) for the lower limbs, and sensory median nerve CSAP, as well as stimulus threshold testing, for the upper limbs.
Almost all of study participants (97%) were female. The majority (66%) had breast cancer and 30% had gynecological cancer. Most (73%) were receiving a weekly regimen of paclitaxel, and the remainder were treated with taxanes plus platinum once every 3 weeks. By the end of treatment, 82% of the patients had developed CIPN, which was mild in 44% and moderate/severe in 38%.
Nfl levels increased significantly from baseline to after the first dose of chemotherapy (P < .001), “highlighting that nerve damage occurs from the very beginning of treatment,” senior investigator Susanna Park, PhD, told this news organization.
In addition, “patients with higher Nfl levels after a single paclitaxel treatment had greater neuropathy at the end of treatment (higher EORTC scores [P ≤ .026], and higher TNS scores [P ≤ .00]),” added Dr. Park, who is associate professor at the University of Sydney.
“Importantly, we also looked at long-term outcomes beyond the end of chemotherapy, because chronic neuropathy produces a significant burden in cancer survivors,” said Dr. Park.
“Among a total of 44 patients who completed the 6- to 12-month post-treatment follow-up, NfL levels after a single treatment were linked to severity of nerve damage quantified with neurophysiological tests, and greater Nfl levels at mid-treatment were correlated with worse patient and neurologically graded neuropathy at 6-12 months.”
Dr. Park said the results suggest that NfL may provide a biomarker of long-term axon damage and that Nfl assays “may enable clinicians to evaluate the risk of long-term toxicity early during paclitaxel treatment to hopefully provide clinically significant information to guide better treatment titration.”
Currently, she said, CIPN is a prominent cause of dose reduction and early chemotherapy cessation.
“For example, in early breast cancer around 25% of patients experience a dose reduction due to the severity of neuropathy symptoms.” But, she said, “there is no standardized way of identifying which patients are at risk of long-term neuropathy and therefore, may benefit more from dose reduction. In this setting, a biomarker such as Nfl could provide oncologists with more information about the risk of long-term toxicity and take that into account in dose decision-making.”
For some cancers, she added, there are multiple potential therapy options.
“A biomarker such as NfL could assist in determining risk-benefit profile in terms of switching to alternate therapies. However, further studies will be needed to fully define the utility of NfL as a biomarker of paclitaxel neuropathy.”
Promising Research
Commenting on the research for this news organization, Maryam Lustberg, MD, associate professor, director of the Center for Breast Cancer at Smilow Cancer Hospital and Yale Cancer Center, and chief of Breast Medical Oncology at Yale Cancer Center, in New Haven, Connecticut, said the study “builds on a body of work previously reported by others showing that neurofilament light chains as detected in the blood can be associated with early signs of neurotoxic injury.”
She added that the research “is promising, since existing clinical and patient-reported measures tend to under-detect chemotherapy-induced neuropathy until more permanent injury might have occurred.”
Dr. Lustberg, who is immediate past president of the Multinational Association of Supportive Care in Cancer, said future studies are needed before Nfl testing can be implemented in routine practice, but that “early detection will allow earlier initiation of supportive care strategies such as physical therapy and exercise, as well as dose modifications, which may be helpful for preventing permanent damage and improving quality of life.”
The investigators and Dr. Lustberg report no relevant financial relationships.

AT PNS 2024
Oncology Mergers Are on the Rise. How Can Independent Practices Survive?
When he completed his fellowship at Fox Chase Cancer Center in Philadelphia, Moshe Chasky, MD, joined a small five-person practice that rented space from the city’s Jefferson Hospital in Philadelphia. The arrangement seemed to work well for the hospital and the small practice, which remained independent.
Within 10 years, the hospital sought to buy the practice, Alliance Cancer Specialists.
But the oncologists at Alliance did not want to join Jefferson.
The hospital eventually entered into an exclusive agreement with its own medical group to provide inpatient oncology/hematology services at three Jefferson Health–Northeast hospitals and stripped Dr. Chasky and his colleagues of their privileges at those facilities, Medscape Medical News reported last year.
said Jeff Patton, MD, CEO of OneOncology, a management services organization.
A 2020 report from the Community Oncology Alliance (COA), for instance, tracked mergers, acquisitions, and closures in the community oncology setting and found the number of practices acquired by hospitals, known as vertical integration, nearly tripled from 2010 to 2020.
“Some hospitals are pretty predatory in their approach,” Dr. Patton said. If hospitals have their own oncology program, “they’ll employ the referring doctors and then discourage them or prevent them from referring patients to our independent practices that are not owned by the hospital.”
Still, in the face of growing pressure to join hospitals, some community oncology practices are finding ways to survive and maintain their independence.
A Growing Trend
The latest data continue to show a clear trend: Consolidation in oncology is on the rise.
A 2024 study revealed that the pace of consolidation seems to be increasing.
The analysis found that, between 2015 and 2022, the number of medical oncologists increased by 14% and the number of medical oncologists per practice increased by 40%, while the number of practices decreased by 18%.
While about 44% of practices remain independent, the percentage of medical oncologists working in practices with more than 25 clinicians has increased from 34% in 2015 to 44% in 2022. By 2022, the largest 102 practices in the United States employed more than 40% of all medical oncologists.
“The rate of consolidation seems to be rapid,” study coauthor Parsa Erfani, MD, an internal medicine resident at Brigham & Women’s Hospital, Boston, explained.
Consolidation appears to breed more consolidation. The researchers found, for instance, that markets with greater hospital consolidation and more hospital beds per capita were more likely to undergo consolidation in oncology.
Consolidation may be higher in these markets “because hospitals or health systems are buying up oncology practices or conversely because oncology practices are merging to compete more effectively with larger hospitals in the area,” Dr. Erfani told this news organization.
Mergers among independent practices, known as horizontal integration, have also been on the rise, according to the 2020 COA report. These mergers can help counter pressures from hospitals seeking to acquire community practices as well as prevent practices and their clinics from closing.
Although Dr. Erfani’s research wasn’t designed to determine the factors behind consolidation, he and his colleagues point to the Affordable Care Act (ACA) and the federal 340B Drug Pricing Program as potential drivers of this trend.
The ACA encouraged consolidation as a way to improve efficiency and created the need for ever-larger information systems to collect and report quality data. But these data collection and reporting requirements have become increasingly difficult for smaller practices to take on.
The 340B Program, however, may be a bigger contributing factor to consolidation. Created in 1992, the 340B Program allows qualifying hospitals and clinics that treat low-income and uninsured patients to buy outpatient prescription drugs at a 25%-50% discount.
Hospitals seeking to capitalize on the margins possible under the 340B Program will “buy all the referring physicians in a market so that the medical oncology group is left with little choice but to sell to the hospital,” said Dr. Patton.
“Those 340B dollars are worth a lot to hospitals,” said David A. Eagle, MD, a hematologist/oncologist with New York Cancer & Blood Specialists and past president of COA. The program “creates an appetite for nonprofit hospitals to want to grow their medical oncology programs,” he told this news organization.
Declining Medicare reimbursement has also hit independent practices hard.
Over the past 15 years, compared with inflation, physicians have gotten “a pay rate decrease from Medicare,” said Dr. Patton. Payers have followed that lead and tried to cut pay for clinicians, especially those who do not have market share, he said. Paying them less is “disingenuous knowing that our costs of providing care are going up,” he said.
Less Access, Higher Costs, Worse Care?
Many studies have demonstrated that, when hospitals become behemoths in a given market, healthcare costs go up.
“There are robust data showing that consolidation increases healthcare costs by reducing competition, including in oncology,” wrote Dr. Erfani and colleagues.
Oncology practices that are owned by hospitals bill facility fees for outpatient chemotherapy treatment, adding another layer of cost, the researchers explained, citing a 2019 Health Economics study.
Another analysis, published in 2020, found that hospital prices for the top 37 infused cancer drugs averaged 86% more per unit than the price charged by physician offices. Hospital outpatient departments charged even more, on average, for drugs — 128% more for nivolumab and 428% more for fluorouracil, for instance.
In their 2024 analysis, Dr. Erfani and colleagues also found that increased hospital market concentration was associated with worse quality of care, across all assessed patient satisfaction measures, and may result in worse access to care as well.
Overall, these consolidation “trends have important implications for cancer care cost, quality, and access,” the authors concluded.
Navigating the Consolidation Trend
In the face of mounting pressure to join hospitals, community oncology practices have typically relied on horizontal mergers to maintain their independence. An increasing number of practices, however, are now turning to another strategy: Management services organizations.
According to some oncologists, a core benefit of joining a management services organization is their community practices can maintain autonomy, hold on to referrals, and benefit from access to a wider network of peers and recently approved treatments such as chimeric antigen receptor T-cell therapies.
In these arrangements, the management company also provides business assistance to practices, including help with billing and collection, payer negotiations, supply chain issues, and credentialing, as well as recruiting, hiring, and marketing.
These management organizations, which include American Oncology Network, Integrated Oncology Network, OneOncology, and Verdi Oncology, are, however, backed by private equity. According to a 2022 report, private equity–backed management organizations have ramped up arrangements with community oncology practices over the past few years — a trend that has concerned some experts.
The authors of a recent analysis in JAMA Internal Medicine explained that, although private equity involvement in physician practices may enable operational efficiencies, “critics point to potential conflicts of interest” and highlight concerns that patients “may face additional barriers to both accessibility and affordability of care.”
The difference, according to some oncologists, is their practices are not owned by the management services organization; instead, the practices enter contracts that outline the boundaries of the relationship and stipulate fees to the management organizations.
In 2020, Dr. Chasky’s practice, Alliance Cancer Specialists, joined The US Oncology Network, a management services organization wholly owned by McKesson. The organization provides the practice with capital and other resources, as well as access to the Sarah Cannon Research Institute, so patients can participate in clinical trials.
“We totally function as an independent practice,” said Dr. Chasky. “We make our own management decisions,” he said. For instance, if Alliance wants to hire a new clinician, US Oncology helps with the recruitment. “But at the end of the day, it’s our practice,” he said.
Davey Daniel, MD — whose community practice joined the management services organization OneOncology — has seen the benefits of being part of a larger network. For instance, bispecific therapies for leukemias, lymphomas, and multiple myeloma are typically administered at academic centers because of the risk for cytokine release syndrome.
However, physician leaders in the OneOncology network “came up with a playbook on how to do it safely” in the community setting, said Dr. Daniel. “It meant that we were adopting FDA newly approved therapies in a very short course.”
Being able to draw from a wider pool of expertise has had other advantages. Dr. Daniel can lean on pathologists and research scientists in the network for advice on targeted therapy use. “We’re actually bringing precision medicine expertise to the community,” Dr. Daniel said.
Dr. Chasky and Dr. Eagle, whose practice is also part of OneOncology, said that continuing to work in the community setting has allowed them greater flexibility.
Dr. Eagle explained that New York Cancer & Blood Specialists tries to offer patients an appointment within 2 days of a referral, and it allows walk-in visits.
Dr. Chasky leans into the flexibility by having staff stay late, when needed, to ensure that all patients are seen. “We’re there for our patients at all hours,” Dr. Chasky said, adding that often “you don’t have that flexibility when you work for a big hospital system.”
The bottom line is community oncology can still thrive, said Nick Ferreyros, managing director of COA, “as long as we have a healthy competitive ecosystem where [we] are valued and seen as an important part of our cancer care system.”

“Some hospitals are pretty predatory in their approach,” Dr. Patton said. If hospitals have their own oncology program, “they’ll employ the referring doctors and then discourage them or prevent them from referring patients to our independent practices that are not owned by the hospital.”
Still, in the face of growing pressure to join hospitals, some community oncology practices are finding ways to survive and maintain their independence.
A Growing Trend
The latest data continue to show a clear trend: Consolidation in oncology is on the rise.
A 2024 study revealed that the pace of consolidation seems to be increasing.
The analysis found that, between 2015 and 2022, the number of medical oncologists increased by 14% and the number of medical oncologists per practice increased by 40%, while the number of practices decreased by 18%.
While about 44% of practices remain independent, the percentage of medical oncologists working in practices with more than 25 clinicians has increased from 34% in 2015 to 44% in 2022. By 2022, the largest 102 practices in the United States employed more than 40% of all medical oncologists.
“The rate of consolidation seems to be rapid,” study coauthor Parsa Erfani, MD, an internal medicine resident at Brigham & Women’s Hospital, Boston, explained.
Consolidation appears to breed more consolidation. The researchers found, for instance, that markets with greater hospital consolidation and more hospital beds per capita were more likely to undergo consolidation in oncology.
Consolidation may be higher in these markets “because hospitals or health systems are buying up oncology practices or conversely because oncology practices are merging to compete more effectively with larger hospitals in the area,” Dr. Erfani told this news organization.
Mergers among independent practices, known as horizontal integration, have also been on the rise, according to the 2020 COA report. These mergers can help counter pressures from hospitals seeking to acquire community practices as well as prevent practices and their clinics from closing.
Although Dr. Erfani’s research wasn’t designed to determine the factors behind consolidation, he and his colleagues point to the Affordable Care Act (ACA) and the federal 340B Drug Pricing Program as potential drivers of this trend.
The ACA encouraged consolidation as a way to improve efficiency and created the need for ever-larger information systems to collect and report quality data. But these data collection and reporting requirements have become increasingly difficult for smaller practices to take on.
The 340B Program, however, may be a bigger contributing factor to consolidation. Created in 1992, the 340B Program allows qualifying hospitals and clinics that treat low-income and uninsured patients to buy outpatient prescription drugs at a 25%-50% discount.
Hospitals seeking to capitalize on the margins possible under the 340B Program will “buy all the referring physicians in a market so that the medical oncology group is left with little choice but to sell to the hospital,” said Dr. Patton.
“Those 340B dollars are worth a lot to hospitals,” said David A. Eagle, MD, a hematologist/oncologist with New York Cancer & Blood Specialists and past president of COA. The program “creates an appetite for nonprofit hospitals to want to grow their medical oncology programs,” he told this news organization.
Declining Medicare reimbursement has also hit independent practices hard.
Over the past 15 years, compared with inflation, physicians have gotten “a pay rate decrease from Medicare,” said Dr. Patton. Payers have followed that lead and tried to cut pay for clinicians, especially those who do not have market share, he said. Paying them less is “disingenuous knowing that our costs of providing care are going up,” he said.
Less Access, Higher Costs, Worse Care?
Many studies have demonstrated that, when hospitals become behemoths in a given market, healthcare costs go up.
“There are robust data showing that consolidation increases healthcare costs by reducing competition, including in oncology,” wrote Dr. Erfani and colleagues.
Oncology practices that are owned by hospitals bill facility fees for outpatient chemotherapy treatment, adding another layer of cost, the researchers explained, citing a 2019 Health Economics study.
Another analysis, published in 2020, found that hospital prices for the top 37 infused cancer drugs averaged 86% more per unit than the price charged by physician offices. Hospital outpatient departments charged even more, on average, for drugs — 128% more for nivolumab and 428% more for fluorouracil, for instance.
In their 2024 analysis, Dr. Erfani and colleagues also found that increased hospital market concentration was associated with worse quality of care, across all assessed patient satisfaction measures, and may result in worse access to care as well.
Overall, these consolidation “trends have important implications for cancer care cost, quality, and access,” the authors concluded.
Navigating the Consolidation Trend
In the face of mounting pressure to join hospitals, community oncology practices have typically relied on horizontal mergers to maintain their independence. An increasing number of practices, however, are now turning to another strategy: Management services organizations.
According to some oncologists, a core benefit of joining a management services organization is their community practices can maintain autonomy, hold on to referrals, and benefit from access to a wider network of peers and recently approved treatments such as chimeric antigen receptor T-cell therapies.
In these arrangements, the management company also provides business assistance to practices, including help with billing and collection, payer negotiations, supply chain issues, and credentialing, as well as recruiting, hiring, and marketing.
These management organizations, which include American Oncology Network, Integrated Oncology Network, OneOncology, and Verdi Oncology, are, however, backed by private equity. According to a 2022 report, private equity–backed management organizations have ramped up arrangements with community oncology practices over the past few years — a trend that has concerned some experts.
The authors of a recent analysis in JAMA Internal Medicine explained that, although private equity involvement in physician practices may enable operational efficiencies, “critics point to potential conflicts of interest” and highlight concerns that patients “may face additional barriers to both accessibility and affordability of care.”
The difference, according to some oncologists, is their practices are not owned by the management services organization; instead, the practices enter contracts that outline the boundaries of the relationship and stipulate fees to the management organizations.
In 2020, Dr. Chasky’s practice, Alliance Cancer Specialists, joined The US Oncology Network, a management services organization wholly owned by McKesson. The organization provides the practice with capital and other resources, as well as access to the Sarah Cannon Research Institute, so patients can participate in clinical trials.
“We totally function as an independent practice,” said Dr. Chasky. “We make our own management decisions,” he said. For instance, if Alliance wants to hire a new clinician, US Oncology helps with the recruitment. “But at the end of the day, it’s our practice,” he said.
Davey Daniel, MD — whose community practice joined the management services organization OneOncology — has seen the benefits of being part of a larger network. For instance, bispecific therapies for leukemias, lymphomas, and multiple myeloma are typically administered at academic centers because of the risk for cytokine release syndrome.
However, physician leaders in the OneOncology network “came up with a playbook on how to do it safely” in the community setting, said Dr. Daniel. “It meant that we were adopting FDA newly approved therapies in a very short course.”
Being able to draw from a wider pool of expertise has had other advantages. Dr. Daniel can lean on pathologists and research scientists in the network for advice on targeted therapy use. “We’re actually bringing precision medicine expertise to the community,” Dr. Daniel said.
Dr. Chasky and Dr. Eagle, whose practice is also part of OneOncology, said that continuing to work in the community setting has allowed them greater flexibility.
Dr. Eagle explained that New York Cancer & Blood Specialists tries to offer patients an appointment within 2 days of a referral, and it allows walk-in visits.
Dr. Chasky leans into the flexibility by having staff stay late, when needed, to ensure that all patients are seen. “We’re there for our patients at all hours,” Dr. Chasky said, adding that often “you don’t have that flexibility when you work for a big hospital system.”
The bottom line is community oncology can still thrive, said Nick Ferreyros, managing director of COA, “as long as we have a healthy competitive ecosystem where [we] are valued and seen as an important part of our cancer care system.”

Doctors Endorsing Products on X May Not Disclose Company Ties
Lead author Aaron Mitchell, MD, MPH, a medical oncologist at Memorial Sloan Kettering Cancer Center in New York City, told this news organization that he and his colleagues undertook the study in part to see whether physicians were adhering to professional and industry guidelines regarding marketing communications.
The team reviewed posts by physicians on X during 2022, looking for key words that might indicate that the posts were intended as endorsements of a product. The researchers then delved into the Centers for Medicare and Medicaid Services Open Payments database to see how many of those identified as having endorsed a product were paid by the manufacturers.
What Dr. Mitchell found concerned him, he said.
Overall, the researchers identified 28 physician endorsers who received a total of $1.4 million from sponsors in 2022. Among these, 26 physicians (93%) received payments from the product’s manufacturer, totaling $713,976, and 24 physicians (86%) accepted payments related to the endorsed drug or device, totaling $492,098.
While most did disclose that the posts were sponsored — by adding the word “sponsored” or using #sponsored — nine physicians did not.
Although 28 physician endorsers represent a “small fraction” of the overall number of physicians who use X, each endorsement was ultimately posted dozens, if not hundreds of times, said Dr. Mitchell. In fact, he said he saw the same particular endorsement post every time he opened his X app for months.
Overall, Dr. Mitchell noted that it’s less about the fact that the endorsements are occurring on social media and more that there are these paid endorsements taking place at all.
Among the physician specialties promoting a product, urologists and oncologists dominated. Almost one third were urologists, and 57% were oncologists — six medical oncologists, six radiation oncologists, and four gynecologic oncologists. Of the remaining three physicians, two were internists and one was a pulmonary and critical care medicine specialist.
The authors tracked posts from physicians and industry accounts. Many of the posts on industry accounts were physician testimonials, usually videos. Almost half — 8 of 17 — of those testimonials did not disclose that the doctor was being paid by the manufacturer. In another case, a physician did not disclose that they were paid to endorse a white paper.
Fifteen promotional posts were for a Boston Scientific product, followed by six for GlaxoSmithKline, two for Eisai, two for Exelixis, and one each for AstraZeneca, Novartis, and Pfizer.
In general, Dr. Mitchell said, industry guidelines suggest that manufacturer-paid speakers or consultants should have well-regarded expertise in the area they are being asked to weigh in on, but most physician endorsers in the study were not key opinion leaders or experts.
The authors examined the paid endorsers’ H-index — a measure of academic productivity provided by Scopus. Overall, 19 of the 28 physicians had an H-index below 20, which is considered less accomplished, and 14 had no published research related to the endorsed product.
Ten received payments from manufacturers for research purposes, and only one received research payments related to the endorsed product ($224,577).
“Physicians’ participation in industry marketing raises questions regarding professionalism and their responsibilities as patient advocates,” the JAMA authors wrote.
The study was supported by grants from the National Cancer Institute. Dr. Mitchell reported no relevant financial relationships. Coauthors Samer Al Hadidi, MD, reported receiving personal fees from Pfizer, Sanofi, and Janssen during the conduct of the study, and Timothy S. Anderson, MD, reported receiving grants from the National Institute on Aging, the American Heart Association, and the American College of Cardiology, and receiving consulting fees from the American Medical Student Association. Dr. Anderson is also an associate editor of JAMA Internal Medicine.

One Patient Changed This Oncologist’s View of Hope. Here’s How.
CHICAGO — Carlos, a 21-year-old, lay in a hospital bed, barely clinging to life. Following a stem cell transplant for leukemia, Carlos had developed a life-threatening case of graft-vs-host disease.
But Carlos’ mother had faith.
“I have hope things will get better,” she said, via interpreter, to Richard Leiter, MD, a palliative care doctor in training at that time.
“I hope they will,” Dr. Leiter told her.
“I should have stopped there,” said Dr. Leiter, recounting an early-career lesson on hope during the ASCO Voices session at the American Society of Clinical Oncology annual meeting. “But in my eagerness to show my attending and myself that I could handle this conversation, I kept going, mistakenly.”
“But none of us think they will,” Dr. Leiter continued.
Carlos’ mother looked Dr. Leiter in the eye. “You want him to die,” she said.
“I knew, even then, that she was right,” recalled Dr. Leiter, now a palliative care physician at Dana-Farber Cancer Institute and Brigham and Women’s Hospital and an assistant professor of medicine at Harvard Medical School, Boston.
Although there was nothing he could do to save Carlos, Dr. Leiter also couldn’t sit with the extreme suffering. “The pain was too great,” Dr. Leiter said. “I needed her to adopt our narrative that we had done everything we could to help him live, and now, we would do everything we could to help his death be a comfortable one.”
But looking back, Dr. Leiter realized, “How could we have asked her to accept what was fundamentally unacceptable, to comprehend the incomprehensible?”
The Importance of Hope
Alan B. Astrow, MD, said during an ASCO symposium on “The Art and Science of Hope.”
“How we think about hope directly influences patient care,” said Dr. Astrow, chief of hematology and medical oncology at NewYork-Presbyterian Brooklyn Methodist Hospital and a professor of clinical medicine at Weill Cornell Medicine in New York City.
Hope, whatever it turns out to be neurobiologically, is “very much a gift” that underlies human existence, he said.
Physicians have the capacity to restore or shatter a patient’s hopes, and those who come to understand the importance of hope will wish to extend the gift to others, Dr. Astrow said.
Asking patients about their hopes is the “golden question,” Steven Z. Pantilat, MD, said at the symposium. “When you think about the future, what do you hope for?”
Often, the answers reveal not only “things beyond a cure that matter tremendously to the patient but things that we can help with,” said Dr. Pantilat, professor and chief of the Division of Palliative Medicine at the University of California San Francisco.
Dr. Pantilat recalled a patient with advanced pancreatic cancer who wished to see her daughter’s wedding in 10 months. He knew that was unlikely, but the discussion led to another solution.
Her daughter moved the wedding to the ICU.
Hope can persist and uplift even in the darkest of times, and “as clinicians, we need to be in the true hope business,” he said.
While some patients may wish for a cure, others may want more time with family or comfort in the face of suffering. People can “hope for all the things that can still be, despite the fact that there’s a lot of things that can’t,” he said.
However, fear that a patient will hope for a cure, and that the difficult discussions to follow might destroy hope or lead to false hope, sometimes means physicians won’t begin the conversation.
“We want to be honest with our patients — compassionate and kind, but honest — when we talk about their hopes,” Dr. Pantilat explained. Sometimes that means he needs to tell patients, “I wish that could happen. I wish I had a treatment that could make your cancer go away, but unfortunately, I don’t. So let’s think about what else we can do to help you.”
Having these difficult discussions matters. The evidence, although limited, indicates that feeling hopeful can improve patients’ well-being and may even boost their cancer outcomes.
One recent study found, for instance, that patients who reported feeling more hopeful also had lower levels of depression and anxiety. Early research also suggests that greater levels of hope may have a hand in reducing inflammation in patients with ovarian cancer and could even improve survival in some patients with advanced cancer.
For Dr. Leiter, while these lessons came early in his career as a palliative care physician, they persist and influence his practice today.
“I know that I could not have prevented Carlos’ death. None of us could have, and none of us could have protected his mother from the unimaginable grief that will stay with her for the rest of her life,” he said. “But I could have made things just a little bit less difficult for her.
“I could have acted as her guide rather than her cross-examiner,” he continued, explaining that he now sees hope as “a generous collaborator” that can coexist with rising creatinine levels, failing livers, and fears about intubation.
“As clinicians, we can always find space to hope with our patients and their families,” he said. “So now, years later when I sit with a terrified and grieving family and they tell me they hope their loved one gets better, I remember Carlos’ mother’s eyes piercing mine ... and I know how to respond: ‘I hope so, too.’ And I do.”

“I could have acted as her guide rather than her cross-examiner,” he continued, explaining that he now sees hope as “a generous collaborator” that can coexist with rising creatinine levels, failing livers, and fears about intubation.
“As clinicians, we can always find space to hope with our patients and their families,” he said. “So now, years later when I sit with a terrified and grieving family and they tell me they hope their loved one gets better, I remember Carlos’ mother’s eyes piercing mine ... and I know how to respond: ‘I hope so, too.’ And I do.”

FROM ASCO 2024
FDA Expands Repotrectinib Label to All NTRK Gene Fusion+ Solid Tumors
The approval is a label expansion for the tyrosine kinase inhibitor (TKI), which received initial clearance in November 2023 for locally advanced or metastatic ROS1-positive non–small cell lung cancer.
NTRK gene fusions are genetic abnormalities wherein part of the NTRK gene fuses with an unrelated gene. The abnormal gene can then produce an oncogenic protein. Although rare, these mutations are found in many cancer types.
The approval, for adult and pediatric patients aged 12 years or older, was based on the single-arm open-label TRIDENT-1 trial in 88 adults with locally advanced or metastatic NTRK gene fusion solid tumors.
In the 40 patients who were TKI-naive, the overall response rate was 58%, and the median duration of response was not estimable. In the 48 patients who had a TKI previously, the overall response rate was 50% and median duration of response was 9.9 months.
In 20% or more of participants, treatment caused dizziness, dysgeusia, peripheral neuropathy, constipation, dyspnea, fatigue, ataxia, cognitive impairment, muscular weakness, and nausea.
Labeling warns of central nervous system reactions, interstitial lung disease/pneumonitis, hepatotoxicity, myalgia with creatine phosphokinase elevation, hyperuricemia, bone fractures, and embryo-fetal toxicity.
The recommended dose is 160 mg orally once daily for 14 days then increased to 160 mg twice daily until disease progression or unacceptable toxicity.
Sixty 40-mg capsules cost around $7,644, according to drugs.com.

Are Children Born Through ART at Higher Risk for Cancer?
The results of a large French study comparing the cancer risk in children conceived through assisted reproductive technology (ART) with that of naturally conceived children were published recently in JAMA Network Open. This study is one of the largest to date on this subject: It included 8,526,306 children born in France between 2010 and 2021, of whom 260,236 (3%) were conceived through ART, and followed them up to a median age of 6.7 years.
Motivations for the Study
ART (including artificial insemination, in vitro fertilization [IVF], or intracytoplasmic sperm injection [ICSI] with fresh or frozen embryo transfer) accounts for about 1 in 30 births in France. However, limited and heterogeneous data have suggested an increased risk for certain health disorders, including cancer, among children conceived through ART. Therefore, a large-scale evaluation of cancer risk in these children is important.
No Overall Increase
In all, 9256 children developed cancer, including 292 who were conceived through ART. Thus, Nevertheless, a slight increase in the risk for leukemia was observed in children conceived through IVF or ICSI. The investigators observed approximately one additional case for every 5000 newborns conceived through IVF or ICSI who reached age 10 years.
Epidemiological monitoring should be continued to better evaluate long-term risks and see whether the risk for leukemia is confirmed. If it is, then it will be useful to investigate the mechanisms related to ART techniques or the fertility disorders of parents that could lead to an increased risk for leukemia.

T-DXd Moves Toward First Line for HER2-Low Metastatic BC
HER2-low cancers express levels of human epidermal growth factor receptor 2 that are below standard thresholds for HER2-positive immunohistochemistry. In 2022, results from the DESTINY-Breast04 trial showed T-DXd (Enhertu, AstraZeneca) to be an effective second-line chemotherapy in patients with HER2-low metastatic breast cancer.
The highly awaited new findings, from the manufacturer-sponsored, open-label Phase 3 DESTINY-Breast06 trial, were presented at the annual meeting of the American Society of Clinical Oncology (ASCO) in Chicago, Illinois.
The findings not only definitively establish a role for T-DXd earlier in the treatment sequence for HER2-low cancers, they also suggest benefit in a group of patients designated for the purposes of this trial to be HER2-ultralow. These patients have cancers with only faintly detectable HER2 expression on currently used assays (J Clin Oncol 42, 2024 [suppl 17; abstr LBA 1000]).
In a separate set of findings also presented at ASCO, from the randomized phase 1B open-label study, DESTINY-Breast07, T-Dxd showed efficacy in previously untreated HER2-positive metastatic breast cancer patients both alone and in combination with the monoclonal antibody pertuzumab (Perjeta, Genentech).
DESTINY-Breast06 Methods and Results
The DESTINY-Breast06 findings were presented by lead investigator Guiseppe Curigliano, MD, PhD, of the University of Milan and European Institute of Oncology. Dr. Curigliano and his colleagues randomized 866 patients with metastatic breast cancer: 436 to intravenous T-Dxd and 430 to the investigator’s choice of capecitabine, nab-paclitaxel, or paclitaxel chemotherapy. The investigators chose capecitabine 60% of the time.
Most patients had cancers classed as HER2 low (immunohistochemistry 1+ or 2+), while 153 had cancers classed by investigators as HER2-ultralow (IHC 0 with membrane staining or IHC under 1+). Patients enrolled in the study were those whose disease had progressed after endocrine therapy with or without targeted therapy. Patients’ median age was between 57 and 58, and all were chemotherapy-naive in the metastatic breast cancer setting.
The main outcome of the study was median progression-free survival in the HER2-low group. T-Dxd was seen improving progression-free survival, with median 13.2 months vs. 8.1 months (hazard ratio, 0.62; 95% confidence interval, 0.51-0.74; P < .0001). In the intention-to-treat population, which included the HER2 ultralow patients, the benefit was the same (HR, 0.63; 95% CI, 0.53-0.75; P < .0001). This suggested that T-DXd is also effective in these patients, and it will be extremely important going forward to identify the lowest level of HER2 expression in metastatic breast cancers that can still benefit from therapy with T-DxD, Dr. Curigliano said.
Overall survival could not be assessed in the study cohort because complete data were not yet available, Dr. Curigliano said. However, trends pointed to an advantage for T-DXd, and tumor response rates were markedly higher with T-DXd: 57% compared with 31% for standard chemotherapy in the full cohort.
Serious treatment-emergent adverse events were more common in the T-Dxd–treated patients, with 11% of that arm developing drug-related interstitial lung disease, and three patients dying of it. Five patients in the T-DXd arm died of adverse events deemed treatment-related, and none died from treatment-related adverse events in the standard chemotherapy arm. Altogether 11 patients died in the T-DXd arm and 6 in the chemotherapy arm.
Clinical Implications of DESTINY-Breast06
The DESTINY-Breast06 data show that “we have to again change how we think about HER2 expression. Even very low levels of HER2 expression matter, and they can be leveraged to improve the treatment for our patients,” said Ian Krop, MD, PhD, of the Yale Cancer Center in New Haven, Connecticut, during the session where the results were presented.
But T-DXd may not be an appropriate first choice for all patients, especially given the safety concerns associated with T-DXd, he continued. With overall survival and quality-of-life data still lacking, clinicians will have to determine on a case-by-case basis who should get T-DXd in the first line.
“For patients who have symptomatic metastatic disease, who need a response to address those symptoms, those in whom you think chemotherapy may not work as well because they had, for example, a short recurrence interval after their adjuvant chemotherapy — using T-DXd in that first-line setting makes perfect sense to take advantage of the substantially higher response rate compared to chemo,” Dr. Krop said. “But for patients who have asymptomatic low burdens of disease, it seems very reasonable to consider using a well-tolerated chemotherapy like capecitabine in the first line, and then using T-DXd in the second line.”
In an interview, Erica Mayer, MD, of the Dana Farber Cancer Institute in Boston, Massachusetts, said patient choice will also matter in determining whether T-DXd is a first-line option. The known toxicity of T-DXd was underscored by the latest findings, she noted, while capecitabine, one of the chemotherapy choices in the control arm of the study, “really reflects what the majority of breast cancer doctors tend to offer, both because of the efficacy of the drug, but also because it’s oral, it’s well tolerated, and you don’t lose your hair.”
DESTINY-Breast07 Results
The DESTINY-Breast07 findings, from a Phase 1B open-label trial measuring safety and tolerability, were presented by Fabrice Andre, MD, PhD, of Université Paris Saclay in Paris, France. Dr. Andre and his colleagues presented the first data comparing T-DXd monotherapy and T-DXd with pertuzumab — a monoclonal antibody targeting HER2 — as a first-line treatment in patients with HER2-overexpressing (immunohistochemistry 3 and above) metastatic breast cancer. (J Clin Oncol 42, 2024 [suppl 16; abstr 1009]).
Current first-line standard of care for these patients is pertuzumab, trastuzumab, and docetaxel, based on results from the 2015 CLEOPATRA trial. T-DXd is currently approved as a second-line treatment.
Dr. Andre and his colleagues randomized 75 patients to monotherapy with T-DXd and 50 to combined therapy, with a median follow-up of 2 years.
After 1 year of treatment, combination of T-DXd and pertuzumab was seen to be associated with a progression-free survival of 89% at 1 year (80% CI, 81.9-93.9), compared with 80% in patients treated with T-DXd alone (80% CI, 73.7-86.1). Objective tumor response rate was 84% for the combined therapy at 12 weeks, with 20% of patients seeing a complete response, compared with 76% and 8%, respectively, for monotherapy.
As in the DESTINY-Breast06 trial, adverse events were high, with interstitial lung disease seen in 9% of patients in the monotherapy group and in 14% of the combined-therapy patients, although no treatment-related deaths occurred.
A randomized phase 3 trial, DESTINY Breast09, will now compare the monotherapy and the combined therapy with standard care.
T-DXd has seen a rapidly expanding role in treating breast and other solid tumors. The DESTINY Breast06 findings will move up its place in the treatment algorithm for metastatic breast cancer, “allowing us to now offer T-DXd as the first chemotherapy choice for patients who are making that transition to chemotherapy over many of the traditional provider choices that we previously have offered,” Dr. Mayer said.
The results “support the use of not only this specific agent, but also the concept of antibody drug conjugates as a very effective way to treat malignancy,” she added.
Dr. Curigliano reported receiving speaker’s fees, research funding, and other support from AstraZeneca and Daiichi Sankyo, among other companies, as did most of his co-authors, of whom three were AstraZeneca employees. Dr. Fabrice disclosed receiving research funding, travel compensation, and/or advisory fees from AstraZeneca and other entities, as did several of his co-authors. Two of his co-authors were employed by AstraZeneca and Roche, manufacturers of the study drugs. Dr. Krop and Dr. Mayer disclosed relationships with AstraZeneca and others.

(J Clin Oncol 42, 2024 [suppl 16; abstr 1009]).
Current first-line standard of care for these patients is pertuzumab, trastuzumab, and docetaxel, based on results from the 2015 CLEOPATRA trial. T-DXd is currently approved as a second-line treatment.
Dr. Andre and his colleagues randomized 75 patients to monotherapy with T-DXd and 50 to combined therapy, with a median follow-up of 2 years.
After 1 year of treatment, combination of T-DXd and pertuzumab was seen to be associated with a progression-free survival of 89% at 1 year (80% CI, 81.9-93.9), compared with 80% in patients treated with T-DXd alone (80% CI, 73.7-86.1). Objective tumor response rate was 84% for the combined therapy at 12 weeks, with 20% of patients seeing a complete response, compared with 76% and 8%, respectively, for monotherapy.
As in the DESTINY-Breast06 trial, adverse events were high, with interstitial lung disease seen in 9% of patients in the monotherapy group and in 14% of the combined-therapy patients, although no treatment-related deaths occurred.
A randomized phase 3 trial, DESTINY Breast09, will now compare the monotherapy and the combined therapy with standard care.
T-DXd has seen a rapidly expanding role in treating breast and other solid tumors. The DESTINY Breast06 findings will move up its place in the treatment algorithm for metastatic breast cancer, “allowing us to now offer T-DXd as the first chemotherapy choice for patients who are making that transition to chemotherapy over many of the traditional provider choices that we previously have offered,” Dr. Mayer said.
The results “support the use of not only this specific agent, but also the concept of antibody drug conjugates as a very effective way to treat malignancy,” she added.
Dr. Curigliano reported receiving speaker’s fees, research funding, and other support from AstraZeneca and Daiichi Sankyo, among other companies, as did most of his co-authors, of whom three were AstraZeneca employees. Dr. Fabrice disclosed receiving research funding, travel compensation, and/or advisory fees from AstraZeneca and other entities, as did several of his co-authors. Two of his co-authors were employed by AstraZeneca and Roche, manufacturers of the study drugs. Dr. Krop and Dr. Mayer disclosed relationships with AstraZeneca and others.

ADCs for Breast Cancer: Clear Benefits, Manageable Risks
These medications, which are designed to selectively deliver potent cytotoxic drugs to cancer cells expressing specific surface antigens such as human epidermal growth factor receptor 2 (HER2) and trophoblast cell surface antigen 2 (TROP2), can be highly effective but can also come with significant toxicities.
The latest data on several ADCs — their clinical benefit and safety — were the focus of three presentations here at the European Society for Medical Oncology (ESMO) Breast Cancer annual congress.
TROPION-Breast01
In her presentation, Komal Jhaveri, MD, of Memorial Sloan Kettering Cancer Center in New York City, reported additional safety analyses from the phase 3 TROPION-Breast01 trial looking at datopotamab deruxtecan (Dato-DXd) in patients with metastatic hormone receptor–positive (HR+)/HER2− breast cancer resistant to endocrine therapy.
Dato-DXd is an investigational ADC composed of a monoclonal antibody targeting TROP2, a transmembrane glycoprotein overexpressed in cancer cells, linked to the topoisomerase 1 inhibitor deruxtecan as the toxic payload.
As previously reported by this news organization, median progression-free survival was 6.9 months with Dato-DXd compared with 4.9 months for investigator’s choice of chemotherapy (eribulin mesylate, vinorelbine, gemcitabine, or capecitabine), which translated into a 37% (hazard ratio [HR], 0.63; P < .0001) reduction in risk for disease progression.
In addition, the rate of grade 3 or higher treatment-related adverse events with Dato-DXd was less than half that with standard chemotherapy and led to fewer dose interruptions or reductions, indicating that Dato-DXd is better tolerated.
Dr. Jhaveri focused on three treatment-related adverse events of special interest: Stomatitis/oral mucositis, ocular surface events, and adjudicated drug-related interstitial lung disease.
The rate of any grade oral mucositis with Dato-DXd was 56%, she reported. Most were grade 1 (25%) or grade 2 (23%), with only 7% grade 3. About 13% of patients had a dose reduction for oral mucositis, and only one (0.3%) patient discontinued treatment.
The median time to onset was 22 days, and median time to resolution (for events recovered/resolved at data cutoff) was 36 days.
“The study did provide toxicity management guidelines for patients who experienced stomatitis,” Dr. Jhaveri told attendees. The guidelines highly recommended daily use of a steroid-containing mouthwash as prophylaxis or, if that wasn’t available, an inert, bland mouth rinse.
“Prophylactic cryotherapy — ice chips or ice water held in the mouth throughout the infusion — was also suggested,” she said.
The overall rate of ocular surface events with Dato-DXd was 40%, with most grade 1 (32%) or grade 2 (7%), with only 0.8% grade 3. Rates of dose reduction/interruption (3.3%) and discontinuation (0.3%) were low. Most ocular events were either dry eye (22%) or keratitis (14%).
The incidence of ocular events in the chemotherapy group was 12%, higher than typically seen. The study mandated regular ocular assessments, and Jhaveri noted that it was possible that this contributed to the high rate of low-grade ocular events found in both arms.
Median time to onset of ocular events was 65 days, and median time to resolution was 67 days.
Toxicity management guidelines were also incorporated for ocular events, suggesting daily use of artificial tears and avoidance of contact lenses, Dr. Jhaveri said.
In the Dato-DXd group, there were 12 adjudicated cases (3.3%) of drug-related interstitial lung disease; most were grade 1 (1.4%) and grade 2 (1.1%).
“There was one patient who had a grade 5 event, which was characterized by the investigator as grade 3 pneumonitis, with death attributed to disease progression,” Dr. Jhaveri said. This was subsequently adjudicated to be a grade 5 drug-related death.
The median time to onset of interstitial lung disease was 84.5 days, and median time to resolution was 28 days.
Among other treatment-related adverse events of clinical interest, any grade nausea was the most common event with Dato-DXd, reported by 51% of patients, with only 1.4% grade 3 or higher.
“Prophylactic antiemetic agents are highly recommended prior to infusion of Dato-DXd and on subsequent days as needed,” Dr. Jhaveri said.
Any grade diarrhea was reported in 7.5%, with no grade 3+ diarrhea. Alopecia was reported in 36.4%, of which grade 1 was 21% and grade 2 was 15%.
Summing up, the researcher said the new safety data suggest that Dato-DXd offers “better tolerability” than standard chemotherapy. Coupled with the efficacy data, this further supports “Dato-DXd as a potential new therapeutic option for patients with previously treated, inoperable, or metastatic HR+/HER2− breast cancer.”
DESTINY-Breast02
New data from the phase 3 DESTINY-Breast02 study confirm a long-term survival benefit, as well as a favorable benefit/risk profile of trastuzumab deruxtecan in patients with HER2+ metastatic breast cancer previously treated with trastuzumab emtansine (T-DM1), reported Sung-Bae Kim, MD, PhD, with University of Ulsan College of Medicine, Seoul, Republic of Korea.
In the phase 3 randomized, multicenter, open-label clinical trial, study participants received either trastuzumab deruxtecan or physician’s choice of trastuzumab plus capecitabine or lapatinib or capecitabine. The primary results of the trial were published last year in The Lancet.
As previously reported by this news organization, after median follow-up of 21.5 months in the trastuzumab deruxtecan group and 18.6 months in the treatment of choice group, median progression-free survival was 17.8 months for trastuzumab deruxtecan vs 6.9 months for the physician’s choice group (HR, 0.36; P < .000001).
The latest data show that after a median follow-up of 30.2 months in the trastuzumab deruxtecan group and 20.5 months in the treatment of choice group, median progression-free survival was 16.7 months with trastuzumab deruxtecan vs 5.5 months with the treatment of choice — a 70% reduction in risk for progression (HR, 0.30), Dr. Kim said.
From time of randomization to progression to next line of therapy or death, median progression-free survival was 33.0 months with trastuzumab deruxtecan vs 15.0 with treatment of choice (HR, 0.42).
Median overall survival was 35.7 months with trastuzumab deruxtecan vs 25.0 months with the treatment of choice, with the risk for death reduced by 31% with trastuzumab deruxtecan (HR, 0.69).
The safety profile of trastuzumab deruxtecan continues to be “manageable, with no long-term toxicity observed with longer follow-up,” Dr. Kim told attendees. The most common treatment-emergent adverse events were nausea (73%), fatigue (62%), and vomiting (38%).
There were a total of 46 (11.4%) adjudicated drug-related interstitial lung disease/pneumonitis cases with trastuzumab deruxtecan. Most were grade 1 or 2. This risk did not increase with longer treatment duration; most events occurred within 12 months of starting treatment, Dr. Kim noted.
With longer follow-up, results of DESTINY-Breast02 “reinforce the substantial benefit” of trastuzumab deruxtecan over the treatment of physician’s choice in patients with HER2+ metastatic breast cancer previously treated with T-DM1, he concluded.
Pooled Data from TROPiCS-02 and EVER-132-002
Hope S. Rugo, MD, of the University of California San Francisco, and colleagues reported a meta-analysis of data from the phase 3 TROPiCS-02 and EVER-132-002 trials of the TROP2-directed ADC sacituzumab govitecan vs the treatment of physician’s choice in HR+/HER2− metastatic breast cancer.
In the pooled analysis, median overall survival was significantly longer with sacituzumab govitecan than with the treatment of physician’s choice in the overall population (16.2 vs 12.7 months) and in patients who received prior CDK4/6 inhibitor treatment (15.4 vs 11.5 months). Progression-free survival also favored sacituzumab govitecan.
These results are consistent with trial-level results from TROPICS-02 and EVER-132-002, reinforcing the efficacy benefits of sacituzumab govitecan over the treatment of physician’s choice, the study team said.
Evolving Landscape of ADCs in Breast Cancer
Giuseppe Curigliano, MD, PhD, with the University of Milan, Italy, who served as discussant for the TROPION-Breast01 safety analysis, noted that the clinical landscape of ADCs has “evolved over time.”
He added that despite having a similar target and similar payload, the anti-TROP2 ADCs in development for HR+/HER2− metastatic breast cancer — Dato-DXd, sacituzumab govitecan, and sacituzumab tirumotecan — appear to have different spectrums of toxicity.
Looking ahead, he said it will be important to determine whether toxicity of these agents can be predicted with a pharmacogenomic analysis and whether toxicity is related to the payload or to the linker antibody complex.
“The science and chemistry of ADCs has shown significant promise in terms of clinical activity, but we also need to better understand safety,” Dr. Curigliano told attendees.
“We need to pay attention to signals in the early phase trials of ADCs and be willing to adjust accordingly to maximize therapeutic benefit and minimize toxicity. Team science will be important in the future developmental ADCs,” he added.
TROPION-Breast01 was sponsored by AstraZeneca. DESTINY-Breast-02 was sponsored by Daiichi Sankyo. TROPiCS-02 and EVER-132-002 were supported by Gilead Sciences. Several trial investigators have disclosed various relationships with these and other pharmaceutical companies.

FROM ESMO BREAST CANCER 2024
The ASCO Annual Meeting Starts This Week
From its origins in 1964, ASCO’s annual event has grown to become the world’s largest clinical oncology meeting, drawing attendees from across the globe.
More than 7000 abstracts were submitted for this year’s meeting a new record — and over 5000 were selected for presentation.
This year’s chair of the Annual Meeting Education Committee, Thomas William LeBlanc, MD, told us he has been attending the meeting since his training days more than a decade ago.
The event is “just incredibly empowering and energizing,” Dr. LeBlanc said, with opportunities to catch up with old colleagues and meet new ones, learn how far oncology has come and where it’s headed, and hear clinical pearls to take back the clinic.
This year’s theme, selected by ASCO President Lynn M. Schuchter, MD, is “The Art and Science of Cancer Care: From Comfort to Cure.”
Dr. LeBlanc, a blood cancer specialist at Duke University, Durham, North Carolina, said the theme has been woven throughout the abstract and educational sessions. Most sessions will have at least one presentation related to how we support people — not only “when we cure them but also when we can’t cure them,” he said.
Topics will include patient well-being, comfort measures, and survivorship. And for the first time the plenary session will include a palliative care abstract that addresses whether or not palliative care can be delivered effectively through telemedicine. The session is on Sunday, June 2.
Other potentially practice changing plenary abstracts tackle immunotherapy combinations for resectable melanoma, perioperative chemotherapy vs neoadjuvant chemoradiation for esophageal cancer, and osimertinib after definitive chemoradiotherapy for unresectable non–small cell lung cancer.
ASCO is piloting a slightly different format for research presentations this year. Instead of starting with context and background, speakers have been asked to present study results upfront as well as repeat them at the end of the talk. The reason behind the tweak is that engagement and retention tend to be better when results are presented upfront, instead of just at the end of a talk.
A popular session — ASCO Voices — has also been given a more central position in the conference: Friday, May 31. In this session, speakers will give short presentations about their personal experiences as providers, researchers, or patients.
ASCO Voices is a relatively recent addition to the meeting that has grown and gotten better. The talks are usually “very powerful narratives” that remind clinicians about “the importance of what they’re doing each day,” Dr. LeBlanc said.
Snippets of the talks will be played while people wait for sessions to begin at the meeting, so attendees who miss the Friday talks can still hear them.
In terms of educational sessions, Dr. LeBlanc highlighted two that might be of general interest to practicing oncologists: A joint ASCO/American Association for Cancer Research session entitled “Drugging the ‘Undruggable’ Target: Successes, Challenges, and the Road Ahead,” on Sunday morning and “Common Sense Oncology: Equity, Value, and Outcomes That Matter” on Monday morning.
As a blood cancer specialist, he said he is particularly interested in the topline results from the ASC4FIRST trial of asciminib, a newer kinase inhibitor, in newly diagnosed chronic myeloid leukemia, presented on Friday.

From its origins in 1964, ASCO’s annual event has grown to become the world’s largest clinical oncology meeting, drawing attendees from across the globe.
More than 7000 abstracts were submitted for this year’s meeting a new record — and over 5000 were selected for presentation.

Exercise Improves Sexual Health in Women With Metastatic Breast Cancer
TOPLINE:
, as well as fatigue and overall quality of life in women with metastatic breast cancer, a randomized controlled trial found.
METHODOLOGY:
- Patients with metastatic breast cancer often experience issues with sexual health. Data on the effectiveness of interventions such as exercise are lacking.
- The PREFERABLE-EFFECT trial enrolled 355 women (mean age, 55.4 years) with metastatic breast cancer; 75% had received first- or second-line treatment at enrollment, and 68% had bone metastases.
- Trial participants were randomly allocated to either usual care or a 9-month (twice weekly) supervised exercise program combining aerobic, resistance, and balance exercises. All participants received general exercise advice and an activity tracker.
- Patients were assessed at baseline and 3, 6, and 9 months. Exercise intervention effects were analyzed on an intent-to-treat basis with mixed models.
TAKEAWAY:
- At baseline, most women showed no interest in sexual activity, and 60% were not sexually active. Nearly half (46%) of sexually active women reported no or little sexual enjoyment. Low sexual function was associated with depression and older age.
- Among patients receiving endocrine therapy, 27% reported vaginal pain and 40% reported vaginal dryness during sexual activity.
- The exercise intervention significantly improved sexual functioning (effect size = 0.28; P = .003) and endocrine sexual symptoms (effect size = 0.25; P = .003) at 6 months, and these effects were sustained at 9 months. Sexual enjoyment also appeared to improve in the exercise group, but due to the small sample size, this was not a statistically significant effect.
- Prior results from the trial showed that the exercise program had significant benefits for fatigue and overall quality of life (primary outcomes).
IN PRACTICE:
Patients with metastatic breast cancer “often suffer from sexual health issues and this topic should be addressed by clinicians,” said study presenter Martina Schmidt, PhD, with the German Cancer Research Center, Heidelberg.
“Physical exercise should be a crucial component of the prescription we offer to our patients,” said study discussant Matteo Lambertini, MD, PhD, with University of Genova, Genova, Italy.
SOURCE:
The research (abstract 269MO) was presented at the European Society for Medical Oncology Breast Cancer 2024 Annual Congress.
LIMITATIONS:
Further research needs to be done to determine the optimal role of exercise in addressing symptom burden.
DISCLOSURES:
This research was funded by the European Union’s Horizon 2020 research and innovation program and the National Health and Medical Research Council of Australia. Dr. Schmidt has no relevant conflicts of interest. Dr. Lambertini has financial relationships with various pharmaceutical companies including Roche, Novartis, AstraZeneca, Lilly, Exact Sciences, Pfizer, and others.
