Short telomere length and immunosuppression: Updates in nonidiopathic pulmonary fibrosis, interstitial lung disease
DIFFUSE LUNG DISEASE AND LUNG TRANSPLANT NETWORK
Interstitial Lung Disease Section
Interstitial lung diseases (ILDs) are a diverse group of relentlessly progressive fibroinflammatory disorders. Pharmacotherapy includes antifibrotics and immunosuppressants as foundational strategies to mitigate loss of lung function. There has been a growing interest in telomere length and its response to immunosuppression in the ILD community.
Telomeres are repetitive nucleotide sequences that “cap” chromosomes and protect against chromosomal shortening during cell replication. Genetic and environmental factors can lead to premature shortening of telomeres. Once a critical length is reached, the cell enters senescence. Short telomere length has been linked to rapid progression, worse outcomes, and poor response to immunosuppressants in idiopathic pulmonary fibrosis (IPF).
Data in patients with non-IPF ILD (which is arguably more difficult to diagnose and manage) were lacking until a recent retrospective cohort study of patients from five centers across the US demonstrated that immunosuppressant exposure in patients with age-adjusted telomere length <10th percentile was associated with a reduced 2-year transplant-free survival in fibrotic hypersensitivity pneumonitis and unclassifiable ILD subgroups.1 This study was underpowered to detect associations in the connective tissue disease-ILD group. Interestingly, authors noted that immunosuppressant exposure was not associated with lung function decline in the short telomere group, suggesting that worse outcomes may be attributable to unmasking extrapulmonary manifestations of short telomeres, such as bone marrow failure and impaired adaptive immunity. Studies like these are essential to guide decision-making in the age of personalized medicine and underscore the necessity for prospective studies to validate these findings.

Expanding recommendations for RSV vaccination
AIRWAYS DISORDERS NETWORK
Asthma and COPD Section
Respiratory syncytial virus (RSV) has been increasingly recognized as a prevalent cause of lower respiratory tract infection (LRTI) among adults in the United States. The risk of hospitalization and mortality from RSV-associated respiratory failure is higher in those with chronic lung disease. In adults aged 65 years or older, RSV has shown to cause up to 160,000 hospitalizations and 10,000 deaths annually.
RSV has been well established as a major cause of LRTI and morbidity among infants. Maternal vaccination with RSVPreF in patients who are pregnant is suggested between 32 0/7 and 36 6/7 weeks of gestation if the date of delivery falls during RSV season to prevent severe illness in young infants in their first months of life. At present, there are no data supporting vaccine administration to patients who are pregnant delivering outside of the RSV season.
What about the rest of the patients? A phase 3b clinical trial to assess the safety and immunogenicity of the RSVPreF3 vaccine in individuals 18 to 49 years of age at increased risk for RSV LRTI, including those with chronic respiratory diseases, is currently underway with projected completion in April 2025 (clinical trials.gov; ID NCT06389487). Additional studies examining safety and immunogenicity combining RSV vaccines with PCV20, influenza, COVID, or Tdap vaccines are also underway. These outcomes will be significant for future recommendations to further lower the risk of developing LRTI, hospitalization, and death among patients less than the age of 60 with chronic lung diseases.

Dubious Medicine
Interest in and knowledge of the gut microbiome, and its role in health and disease, has increased exponentially in the past decade. Billions of dollars have been invested in gut microbiome research since release of the NIH Human Microbiome Project’s reference database in 2012, aimed not only at better understanding pathology and disease mechanisms, but also promoting development of novel diagnostic and therapeutic interventions. However, it is fair to say that gut microbiome research is still in its infancy, and there is still much to be learned.
Despite this, a global, and largely unregulated, industry of direct-to-consumer (DTC) microbiome tests has emerged. These (often costly) tests are now widely available to our patients via retail outlets and online — in exchange for a stool sample, consumers receive a detailed report comparing their microbiome to a “healthy” reference patient and recommending various interventions such as follow-up testing, special diets, or nutritional supplements. By now, we likely all have been handed one of these reports in clinic identifying a patient’s “abnormal” microbiome and asked to weigh in on its dubious results. A special feature article in this month’s issue outlines the controversies surrounding these DTC microbiome tests, which currently lack analytic and clinical validity, and highlights recent calls for increased regulation in this space.
Also We invite you to learn more about the exceptional Dr. Maria Abreu of the University of Miami, who recently assumed her new role as AGA President. Our quarterly Perspectives column tackles the issue of GLP-1 receptor agonists (GLP-1RAs) in GI endoscopy — gastroenterologist Dr. Jana Hashash and anesthesiologists Dr. Thomas Hickey and Dr. Ryan Pouliot offer contrasting perspectives on this topic drawn from AGA and American Society of Anesthesiologists guidance. Finally, our July Member Spotlight features Dr. Lisa Mathew of South Denver Gastroenterology who shares her perspectives on hosting a GI podcast, why private practice is a fantastic laboratory for clinical innovation, and how she found her “tribe” in the field of gastroenterology.

FDA Proposes that Interchangeability Status for Biosimilars Doesn’t Need Switching Studies
The Food and Drug Administration (FDA) has issued new draft guidance that does not require additional switching studies for biosimilars seeking interchangeability. These studies were previously recommended to demonstrate that switching between the biosimilar and its reference product showed no greater risk than using the reference product alone.
“The recommendations in today’s draft guidance, when finalized, will provide clarity and transparency about the FDA’s thinking and align the review and approval process with existing and emerging science,” said Sarah Yim, MD, director of the FDA’s Office of Therapeutic Biologics and Biosimilars in a statement on June 20. “We have gained valuable experience reviewing both biosimilar and interchangeable biosimilar medications over the past 10 years. Both biosimilars and interchangeable biosimilars meet the same high standard of biosimilarity for FDA approval and both are as safe and effective as the reference product.”
An interchangeable status allows a biosimilar product to be swapped with the reference product without involvement from the prescribing provider, depending on state law.
While switching studies were not required under previous FDA guidance, the 2019 document did state that the agency “expects that applications generally will include data from a switching study or studies in one or more appropriate conditions of use.”
However, of the 13 biosimilars that received interchangeability status, 9 did not include switching study data.
“Experience has shown that, for the products approved as biosimilars to date, the risk in terms of safety or diminished efficacy is insignificant following single or multiple switches between a reference product and a biosimilar product,” the FDA stated. The agency’s investigators also conducted a systematic review of switching studies, which found no differences in risk for death, serious adverse events, and treatment discontinuations in participants switched between biosimilars and reference products and those that remained on reference products.
“Additionally, today’s analytical tools can accurately evaluate the structure and effects [of] biologic products, both in the lab (in vitro) and in living organisms (in vivo) with more precision and sensitivity than switching studies,” the agency noted.
The FDA is now calling for commentary on these draft recommendations to be submitted by Aug. 20, 2024.

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.

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.

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.”

Teaching Tips for Dermatology Residents
Dermatology residents interact with trainees of various levels throughout the workday—from undergraduate or even high school students to postgraduate fellows. Depending on the institution’s training program, residents may have responsibilities to teach through lecture series such as Grand Rounds and didactics. Therefore, it is an integral part of resident training to become educators in addition to being learners; however, formal pedagogy education is rare in dermatology programs. 1,2 Herein, I discuss several techniques that residents can apply to their practice to cultivate ideal learning environments and outcomes for trainees.
Creating Effective Teaching and Learning Experiences
Planning to teach can be as important as teaching itself. Developing learning objectives can help to create effective teaching and learning experiences. Learning objectives should be specific, time bound, attainable, and learner centered (Table 1). It is recommended that residents aim for no more than 4 objectives per hour of learning.3 By creating clear learning objectives, residents can make connections between the content and any assessments. Bloom’s taxonomy of cognitive learning objectives gives guidance on action verbs to use in writing learning objectives depending on the cognitive process being tested (Table 2).4
Creating a Safe Educational Environment
Psychological safety is the belief that a learning environment is a safe place in which to take risks.5 A clinical learning environment that is psychologically safe can support trainee well-being and learning. Cultivating a safe educational environment may include addressing microaggressions and bias in the clinical workplace. Table 3 provides examples of statements using the 6 Ds, which can be used to mitigate these issues.6 The first 4—direct, distract, delegate, and defer—represent ways to respond to racism, microaggressions, and bias, and the last 2—display discomfort and debrief—are responses that may be utilized in any problematic incident. Residents can play an important supportive role in scenarios where learners are faced with an incident that may not be regarded as psychologically safe. This is especially true if the learner is at a lower training level than the dermatology resident. We all play a role in creating a safe workplace for our teams.
Teaching in the Clinic and Hospital
There are multiple challenges to teaching in both inpatient and outpatient environments, including limited space and time; thus, more informal teaching methods are common. For example, in an outpatient dermatology clinic, the patient schedule can become a “table of contents” of potential teaching and learning opportunities. This technique is called the focused half day.3,7 By reviewing the clinic schedule, students can focus on a specific area of interest or theme throughout the course of the day.3
Priming and framing are other focused techniques that work well in both outpatient and inpatient settings.3,8,9 Priming means alerting the trainee to upcoming learning objective(s) and focusing their attention on what to observe or do during a shared visit with a patient. Framing—instructing learners to collect information that is relevant to the diagnosis and treatment—allows trainees to help move patient care forward while the resident attends to other patients.3
Modeling involves describing a thought process out loud for a learner3,10; for example, prior to starting a patient encounter, a dermatology resident may clearly state the goal of a patient conversation to the learner, describe their thought process about the topic, summarize the important points, and ask the learner if they have any questions about what was just said. Using this technique, learners may have a better understanding of why and how to go about conducting a patient encounter after the resident models one for them.
Effectively Integrating Visual Media and Presentations
Research supported by the cognitive load theory and cognitive theory of multimedia learning has led to the assertion-evidence approach for creating presentation slides that are built around messages, not topics, and messages are supported with visuals, not bullets.3,11,12 For example, slides should be constructed with 1- to 2-line assertion statements as titles and relevant illustrations or figures as supporting evidence to enhance visual memory.3
Written text on presentation slides often is redundant with spoken narration and also decreases learning because of cognitive load. Busy background colors and/or designs consume working memory and also can be detrimental to learning. Limiting these common distractors in a presentation makes for more effective delivery and retention of knowledge.3
Final Thoughts
There are multiple avenues for teaching as a resident and not all techniques may be applicable depending on the clinical or academic scenario. This column provides a starting point for residents to augment their pedagogical skills, particularly because formal teaching on pedagogy is lacking in medical education.

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.”

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.

Ixekizumab Met Phase 3 Trial Endpoint in Juvenile PsA, Enthesitis-Related Arthritis
VIENNA — Ixekizumab (Taltz), an interleukin-17A inhibitor that’s already approved for the treatment of psoriatic arthritis and axial spondyloarthritis in adults appears likely to be granted the same corresponding indications for children, based on initial results from an open-label, phase 3 trial that employed adalimumab as a reference.
With a safety profile comparable with that seen in adult patients, ixekizumab “met the prespecified criterion for success at 16 weeks,” reported Athimalaipet V. Ramanan, MD, PhD, of Bristol Royal Hospital for Children and Translational Health Sciences, Bristol, England.
In this multicenter, randomized, open-label trial called COSPIRIT-JIA, which is still ongoing, investigators enrolled 101 children with active juvenile PsA (JPsA) or enthesitis-related arthritis (ERA), which is akin to spondyloarthritis in adults.
The efficacy and safety data at 16 weeks were presented as a late-breaking abstract at the annual European Congress of Rheumatology. Dr. Ramanan said that the open-label extension to 104 weeks is underway and further follow-up out to 264 weeks is planned.
Nearly 90% Achieve ACR30
The trial had an adaptive design in which the first 40 patients without biologics experience were randomized to ixekizumab or adalimumab, stratified by JPsA or ERA diagnosis, and the following 61 patients with either no biologic experience or an inadequate response or intolerance to biologics all received ixekizumab. The drugs were dosed according to weight. Dr. Ramanan explained that a placebo-controlled trial was considered unethical because of the strong evidence of benefit from biologics for JPsA and ERA.
The trial easily met its predefined threshold for success, which required ≥ 80% probability, based on Bayesian analysis, that ≥ 50% of patients would have 30% improvement in American College of Rheumatology response criteria (ACR30) at week 16. ACR30 was achieved in 88.9% of those treated with ixekizumab overall vs 95.0% of those treated with adalimumab, but the trial was not designed as a head-to-head comparison. Rather, adalimumab served as a reference.
When compared for the distinct diseases, the ACR30 rates were also numerically lower for ixekizumab relative to adalimumab for both ERA (88.9% vs 93.8%) and JPsA (88.9% vs 100%), but all of the adalimumab patients were naive to biologics. In comparison, about 75% of patients receiving ixekizumab were biologic-therapy naive.
Response rates to ixekizumab overall were numerically higher for patients without previous biologic experience than for those with experience (90.0% vs 85.7%), and this was also the case for patients with ERA (92.5% vs 78.6%). However, in the JPsA group, biologic-experienced patients had higher numerical response rates to ixekizumab (100% vs 85.0%).
An ACR30 is not a clinical goal that satisfies most patients and clinicians, Dr. Ramanan conceded, but he noted that ACR50 was reached with ixekizumab by 81.5% with ERA and 74.1% with JPsA, and ACR70 was reached by 68.5% and 55.6%, respectively. The highest responses of ACR90 (27.8% and 33.3%) and ACR100 (14.8% and 25.9%) were lower but still substantial in the ERA and JPsA groups, respectively.
Through week 16, 58.0% of those treated with ixekizumab had an adverse event considered treatment-related. Nearly half were of mild severity, and the remainder were moderate. Only 3.7% were considered serious. No patient discontinued study treatment because of an adverse event.
In this study, the presence of at least three active peripheral joints was an inclusion criterion. The median age was about 13 years in the biologic-naive adalimumab and ixekizumab groups and 14 years in the ixekizumab biologic-experienced group. The youngest patient in the study was aged 5 years, and the oldest was aged 18 years. Although about 40% of patients were women in the two biologic-naive subgroups, it was 60% in the biologic-experienced group.
On average, patients in the biologic-naive group were entered about 1 year after diagnosis. In the experienced patients, the average duration of disease at entry was nearly 4 years. About 45% of patients remained on conventional synthetic disease-modifying antirheumatic drugs while receiving ixekizumab. The proportion was 35% in the adalimumab reference arm.
Ixekizumab Might Fulfill Need for More Options
There are several biologics that have received regulatory approval or are already widely used for the treatment of JPsA or ERA, but more options are needed, according to Dr. Ramanan and the chair of the abstract session in which these data were reported. According to Caroline Ospelt, MD, PhD, a researcher at the Center for Experimental Rheumatology, University Hospital Zurich, Switzerland, regulatory approval of ixekizumab will depend on sustained efficacy and safety in longer follow-up from the COSPIRIT-JIA trial, but this trial supports continued development.
Despite a novel mechanism of action, “the data so far suggest a level of efficacy similar to that of anti-TNF [anti-tumor necrosis factor] biologics,” said Dr. Ospelt, who, in addition to moderating the late-breaking session, served as Scientific Program Chair of EULAR 2024.
While Dr. Ospelt emphasized that she is a researcher involved in translational rheumatology studies and not a clinician, she said there was consensus within the program committee to select this abstract from other high-quality latebreaker submissions on the basis of its potential clinical significance.
Dr. Ramanan reported financial relationships with AbbVie, AstraZeneca, Novartis, Pfizer, Roche, SOBI, UCB, and Eli Lilly, which provided funding for this study. Dr. Ospelt reported no potential conflicts of interest.

Ixekizumab Might Fulfill Need for More Options
There are several biologics that have received regulatory approval or are already widely used for the treatment of JPsA or ERA, but more options are needed, according to Dr. Ramanan and the chair of the abstract session in which these data were reported. According to Caroline Ospelt, MD, PhD, a researcher at the Center for Experimental Rheumatology, University Hospital Zurich, Switzerland, regulatory approval of ixekizumab will depend on sustained efficacy and safety in longer follow-up from the COSPIRIT-JIA trial, but this trial supports continued development.
Despite a novel mechanism of action, “the data so far suggest a level of efficacy similar to that of anti-TNF [anti-tumor necrosis factor] biologics,” said Dr. Ospelt, who, in addition to moderating the late-breaking session, served as Scientific Program Chair of EULAR 2024.
While Dr. Ospelt emphasized that she is a researcher involved in translational rheumatology studies and not a clinician, she said there was consensus within the program committee to select this abstract from other high-quality latebreaker submissions on the basis of its potential clinical significance.
Dr. Ramanan reported financial relationships with AbbVie, AstraZeneca, Novartis, Pfizer, Roche, SOBI, UCB, and Eli Lilly, which provided funding for this study. Dr. Ospelt reported no potential conflicts of interest.

VIENNA — Ixekizumab (Taltz), an interleukin-17A inhibitor that’s already approved for the treatment of psoriatic arthritis and axial spondyloarthritis in adults appears likely to be granted the same corresponding indications for children, based on initial results from an open-label, phase 3 trial that employed adalimumab as a reference.
With a safety profile comparable with that seen in adult patients, ixekizumab “met the prespecified criterion for success at 16 weeks,” reported Athimalaipet V. Ramanan, MD, PhD, of Bristol Royal Hospital for Children and Translational Health Sciences, Bristol, England.
In this multicenter, randomized, open-label trial called COSPIRIT-JIA, which is still ongoing, investigators enrolled 101 children with active juvenile PsA (JPsA) or enthesitis-related arthritis (ERA), which is akin to spondyloarthritis in adults.
The efficacy and safety data at 16 weeks were presented as a late-breaking abstract at the annual European Congress of Rheumatology. Dr. Ramanan said that the open-label extension to 104 weeks is underway and further follow-up out to 264 weeks is planned.
Nearly 90% Achieve ACR30
The trial had an adaptive design in which the first 40 patients without biologics experience were randomized to ixekizumab or adalimumab, stratified by JPsA or ERA diagnosis, and the following 61 patients with either no biologic experience or an inadequate response or intolerance to biologics all received ixekizumab. The drugs were dosed according to weight. Dr. Ramanan explained that a placebo-controlled trial was considered unethical because of the strong evidence of benefit from biologics for JPsA and ERA.
The trial easily met its predefined threshold for success, which required ≥ 80% probability, based on Bayesian analysis, that ≥ 50% of patients would have 30% improvement in American College of Rheumatology response criteria (ACR30) at week 16. ACR30 was achieved in 88.9% of those treated with ixekizumab overall vs 95.0% of those treated with adalimumab, but the trial was not designed as a head-to-head comparison. Rather, adalimumab served as a reference.
When compared for the distinct diseases, the ACR30 rates were also numerically lower for ixekizumab relative to adalimumab for both ERA (88.9% vs 93.8%) and JPsA (88.9% vs 100%), but all of the adalimumab patients were naive to biologics. In comparison, about 75% of patients receiving ixekizumab were biologic-therapy naive.
Response rates to ixekizumab overall were numerically higher for patients without previous biologic experience than for those with experience (90.0% vs 85.7%), and this was also the case for patients with ERA (92.5% vs 78.6%). However, in the JPsA group, biologic-experienced patients had higher numerical response rates to ixekizumab (100% vs 85.0%).
An ACR30 is not a clinical goal that satisfies most patients and clinicians, Dr. Ramanan conceded, but he noted that ACR50 was reached with ixekizumab by 81.5% with ERA and 74.1% with JPsA, and ACR70 was reached by 68.5% and 55.6%, respectively. The highest responses of ACR90 (27.8% and 33.3%) and ACR100 (14.8% and 25.9%) were lower but still substantial in the ERA and JPsA groups, respectively.
Through week 16, 58.0% of those treated with ixekizumab had an adverse event considered treatment-related. Nearly half were of mild severity, and the remainder were moderate. Only 3.7% were considered serious. No patient discontinued study treatment because of an adverse event.
In this study, the presence of at least three active peripheral joints was an inclusion criterion. The median age was about 13 years in the biologic-naive adalimumab and ixekizumab groups and 14 years in the ixekizumab biologic-experienced group. The youngest patient in the study was aged 5 years, and the oldest was aged 18 years. Although about 40% of patients were women in the two biologic-naive subgroups, it was 60% in the biologic-experienced group.
On average, patients in the biologic-naive group were entered about 1 year after diagnosis. In the experienced patients, the average duration of disease at entry was nearly 4 years. About 45% of patients remained on conventional synthetic disease-modifying antirheumatic drugs while receiving ixekizumab. The proportion was 35% in the adalimumab reference arm.

FROM EULAR 2024
Atopic Dermatitis: Study Compares Prevalence by Gender, Age, and Ethnic Background
than adults from other ethnic backgrounds.
Those are among the key findings from an analysis of nationally representative cross-sectional data that were presented during a late-breaking abstract session at the Revolutionizing Atopic Dermatitis conference in Chicago.
“In the past few years, there has been a much-needed focus on better understanding disparities in atopic dermatitis,” one of the study authors, Raj Chovatiya, MD, PhD, clinical associate professor at Chicago Medical School, Rosalind Franklin University, North Chicago, told this news organization after the conference.
“Epidemiology is one of the key ways in which we can query differences in AD at a population level.”
Drawing from the 2021 National Health Interview Survey, the researchers identified 3103 respondents who reported being diagnosed with AD or eczema. They estimated the prevalence rates of AD for the overall population and each subgroup by dividing US frequency estimates by their corresponding US population totals and used multivariable logistic regression to assess the odds of having AD.
More than half of the respondents (1643) were aged between 18 and 64 years, 522 were aged 65 years and older, and 922 were children younger than 18 years. Overall, the prevalence of AD was 7.6% in adults aged 18-64 years and 6.1% in adults aged 65 years and older, for a weighted US estimate of 15.3 and 3.2 million, respectively. The prevalence of AD varied by race/ethnicity and was highest for those from “other single and multiple races” group (12.4%), followed by Black/African American (8.5%), White (7.7%), Asian (6.5%), American Indian/Alaskan Native (4.9%), and Hispanic (4.8%) populations.
In children, race/ethnicity prevalence were highest for those from other single and multiple races (15.2.%), followed by Black/African American (14.2%), American Indian/Alaskan Native (12%), White (10.2%), Hispanic (9.5%), and Asian (9%) populations.
When the researchers combined all age groups, they observed higher prevalence rates of AD among females than among males. However, in an analysis limited to children, the prevalence rates were similar between girls and boys (10.8% vs 10.7%, respectively), for a weighted US estimate of 7.8 million children with AD.
On multiple regression, the odds of having AD were greater among women than among men (odds ratio [OR], 1.4), among adults aged 18-64 years than among those aged 65 years and older (OR, 1.4), among those younger than 18 years than among those aged 65 years and older (OR, 2.0), and among Black/African American individuals than among White individuals (OR, 1.2). Hispanic adults had a lower risk for AD than non-Hispanic White adults (OR, 0.69) as did Asian adults than White adults (OR, 0.82).
“We found AD prevalence rates were higher in children and adult females, Hispanic adults had a lower prevalence of AD than all other adult groups, and there were numerical differences in AD prevalence across racial groups,” Dr. Chovatiya said in the interview. “While there are of course limitations to the use of any nationally representative cross-sectional dataset that requires weighting to project results from a smaller sample to reflect a larger more heterogeneous group, these results are important for us to consider targeted strategies to address AD burden.”
Jonathan I. Silverberg, MD, PhD, professor of dermatology at The George Washington University, Washington, who was asked to comment on the study, said that while the prevalence of AD in children has been well documented in prior research, “this study fills an important gap by showing us that the prevalence does remain high in adults.”
In addition, “it has not shown any evidence of AD decreasing over time; if anything, it might be slightly increasing,” he said. “We’re also seeing differences [in AD] by race and ethnicity. We have seen that demonstrated in children but [has been] less clearly demonstrated in adults.”
Eli Lilly and Company funded the analysis. Dr. Chovatiya and Dr. Silverberg disclosed ties to several pharmaceutical companies, including Eli Lilly.
