Feature

Childhood cancers represent a diverse group of neoplasms, and thanks to advances in treatment, survival rates have improved significantly. Today, more than 80%-85% of children diagnosed with cancer in developed countries survive into adulthood.

This increase in survival has brought new challenges, however. Compared with the general population, childhood cancer survivors (CCS) are at a notably higher risk for early mortality, developing secondary cancers, and experiencing various long-term clinical and psychosocial issues stemming from their disease or its treatment.

Long-term follow-up care for CCS is a complex and evolving field. Despite ongoing efforts to establish global and national guidelines, current evidence indicates that the care and management of these patients remain suboptimal.

Sexual dysfunction is a common and significant late effect among CCS. The disruptions caused by cancer and its treatment can interfere with normal physiological and psychological development, leading to issues with sexual function. This aspect of health is critical as it influences not just physical well-being but also psychosocial, developmental, and emotional health.
 

Characteristics and Mechanisms

Sexual functioning encompasses the physiological and psychological aspects of sexual behavior, including desire, arousal, orgasm, sexual pleasure, and overall satisfaction.

As CCS reach adolescence or adulthood, they often face sexual and reproductive issues, particularly as they enter romantic relationships.

Sexual functioning is a complex process that relies on the interaction of various factors, including physiological health, psychosexual development, romantic relationships, body image, and desire.

Despite its importance, the impact of childhood cancer on sexual function is often overlooked, even though cancer and its treatments can have lifelong effects. 
 

Sexual Function in CCS

A recent review aimed to summarize the existing research on sexual function among CCS, highlighting assessment tools, key stages of psychosexual development, common sexual problems, and the prevalence of sexual dysfunction.

The review study included 22 studies published between 2000 and 2022, comprising two qualitative, six cohort, and 14 cross-sectional studies.

Most CCS reached all key stages of psychosexual development at an average age of 29.8 years. Although some milestones were achieved later than is typical, many survivors felt they reached these stages at the appropriate time. Sexual initiation was less common among those who had undergone intensive neurotoxic treatments, such as those diagnosed with brain tumors or leukemia in childhood.

In a cross-sectional study of CCS aged 17-39 years, about one third had never engaged in sexual intercourse, 41.4% reported never experiencing sexual attraction, 44.8% were dissatisfied with their sex lives, and many rarely felt sexually attractive to others. Another study found that common issues among CCS included a lack of interest in sex (30%), difficulty enjoying sex (24%), and difficulty becoming aroused (23%). However, comparing and analyzing these problems was challenging due to the lack of standardized assessment criteria.

The prevalence of sexual dysfunction among CCS ranged from 12.3% to 46.5%. For males, the prevalence ranged from 12.3% to 54.0%, while for females, it ranged from 19.9% to 57.0%.
 

Factors Influencing Sexual Function

The review identified the following four categories of factors influencing sexual function in CCS: Demographic, treatment-related, psychological, and physiological.

Demographic factors: Gender, age, education level, relationship status, income level, and race all play roles in sexual function.

Female survivors reported more severe sexual dysfunction and poorer sexual health than did male survivors. Age at cancer diagnosis, age at evaluation, and the time since diagnosis were closely linked to sexual experiences. Patients diagnosed with cancer during childhood tended to report better sexual function than those diagnosed during adolescence.

Treatment-related factors: The type of cancer and intensity of treatment, along with surgical history, were significant factors. Surgeries involving the spinal cord or sympathetic nerves, as well as a history of prostate or pelvic surgery, were strongly associated with erectile dysfunction in men. In women, pelvic surgeries and treatments to the pelvic area were commonly linked to sexual dysfunction.

The association between treatment intensity and sexual function was noted across several studies, although the results were not always consistent. For example, testicular radiation above 10 Gy was positively correlated with sexual dysfunction. Women who underwent more intensive treatments were more likely to report issues in multiple areas of sexual function, while men in this group were less likely to have children.

Among female CCS, certain types of cancer, such as germ cell tumors, renal tumors, and leukemia, present a higher risk for sexual dysfunction. Women who had CNS tumors in childhood frequently reported problems like difficulty in sexual arousal, low sexual satisfaction, infrequent sexual activity, and fewer sexual partners, compared with survivors of other cancers. Survivors of acute lymphoblastic leukemia and those who underwent hematopoietic stem cell transplantation (HSCT) also showed varying degrees of impaired sexual function, compared with the general population. The HSCT group showed significant testicular damage, including reduced testicular volumes, low testosterone levels, and low sperm counts.

Psychological factors: These factors, such as emotional distress, play a significant role in sexual dysfunction among CCS. Symptoms like anxiety, nervousness during sexual activity, and depression are commonly reported by those with sexual dysfunction. The connection between body image and sexual function is complex. Many CCS with sexual dysfunction express concern about how others, particularly their partners, perceived their altered body image due to cancer and its treatment.

Physiological factors: In male CCS, low serum testosterone levels and low lean muscle mass are linked to an increased risk for sexual dysfunction. Treatments involving alkylating agents or testicular radiation, and surgery or radiotherapy targeting the genitourinary organs or the hypothalamic-pituitary region, can lead to various physiological and endocrine disorders, contributing to sexual dysfunction. Despite these risks, there is a lack of research evaluating sexual function through the lens of the hypothalamic-pituitary-gonadal axis and neuroendocrine pathways.

A new “best practices” guide released by the Alliance for Pharmacy Compounding (APC) aims to educate compounding pharmacists and reassure prescribers about the ethical, legal, and practical considerations that must be addressed to ensure quality standards and protect patients’ health.

Endocrinologists have expressed skepticism about the quality of compounded drugs, particularly the popular glucagon-like peptide 1 (GLP-1) semaglutide. The Food and Drug Administration (FDA) recently issued an alert linking hospitalizations to overdoses of compounded semaglutide.

“This document goes beyond today’s media-grabbing shortages,” APC Board Chair-Elect Gina Besteman, RPh, of Belmar Pharma Solutions told this news organization. “We developed these best practices to apply to all shortage drug compounding, and especially in this moment when so many are compounding GLP-1s. These serve as a reminder about what compliance and care look like.”

Prescribers determine whether a patient needs a compounded medication, not pharmacists, Ms. Besteman noted. “A patient-specific prescription order must be authorized for a compounded medication to be dispensed. Prescribers should ensure pharmacies they work with regularly check the FDA Drug Shortage List, as compounding of ‘essential copies’ of FDA-approved drugs is only allowed when a drug is listed as ‘currently in shortage.’ ”
 

Framework for Compounding

“With fake and illegal online stores popping up, it’s critical for legitimate, state-licensed compounding pharmacies to maintain the profession’s high standards,” the APC said in a media communication.

Highlights of its best practices, which are directed toward 503A state-licensed compounding pharmacies, include the following, among others:

• Pharmacies should check the FDA drug shortage list prior to preparing a copy of an FDA-approved drug and maintain documentation to demonstrate to regulators that the drug was in shortage at the time it was compounded.
• Pharmacies may only source active pharmaceutical ingredients (APIs) from state-licensed wholesalers who purchase from FDA-registered manufacturers or order directly from FDA-registered manufacturers.
• Verify from the wholesaler that the manufacturer is registered with the FDA and the API meets all the requirements of section 503A, and that both hold the appropriate permits or licenses in their home state and the shipped to state.
• Adhere to USP Chapter <797> testing requirements for sterility, endotoxin, stability, particulate, antimicrobial effectiveness, and container closure integrity studies.
• Counseling must be offered to the patient or the patient’s agent/caregiver. Providing written information that assists in the understanding of how to properly use the compounded medication is advised.
• Instructions should be written in a way that a layperson can understand (especially directions including dosage titrations and conversions between milligrams and milliliters or units).
• Like all medications, compounded drugs can only be prescribed in the presence of a valid patient-practitioner relationship and can only be dispensed by a pharmacy after receipt of a valid patient-specific prescription order.
• When marketing, never make claims of safety or efficacy of the compounded product.
• Advertising that patients will/may save money using compounded medications, compared with manufactured products is not allowed.

“Compounding FDA-approved drugs during shortages is nothing new — pharmacies have been doing it well before GLP-1s came on the scene, and they’ll continue long after this current shortage ends,” Ms. Besteman said. “Prescribers should be aware of APC’s guidelines because they provide a framework for ethically and legally compounding medications during drug shortages.

“To paraphrase The Police,” she concluded, “every move you make, every step you take, they’ll be watching you. Make sure they see those best practices in action.”
 

‘Reduces the Risks’

Commenting on the best practices guidance, Ivania Rizo, MD, director of Obesity Medicine and Diabetes and clinical colead at Boston Medical Center’s Health Equity Accelerator in Massachusetts, said: “These best practices will hopefully make a difference in the quality of compounded drugs.”

“The emphasis on rigorous testing of APIs and adherence to USP standards is particularly important for maintaining drug quality,” she noted. “This structured approach reduces the risk of variability and ensures that compounded drugs meet high-quality standards, thus enhancing their reliability.”

“Knowing that compounding pharmacies are adhering to rigorous standards for sourcing, testing, and compounding can at least reassure clinicians that specific steps are being taken for the safety and efficacy of these medications,” she said. “The transparency in documenting compliance with FDA guidelines and maintaining high-quality control measures can enhance trust among healthcare providers.”

Although clinicians are likely to have more confidence in compounded drugs when these best practices are followed, she said, “overall, we all hope that the shortages of medications such as tirzepatide are resolved promptly, allowing patients to access FDA-approved drugs without the need for compounding.”

“While the implementation of best practices for compounding during shortages is a positive and necessary step, our ultimate goal remains to address and resolve these shortages in the near future,” she concluded.

Dr. Rizo declared no competing interests.

Since the first Food and Drug Administration approval of a Janus kinase (JAK) inhibitor in 2011, the number of these medications available — and their treatment indications — have continued to grow. Prescribing physicians are familiar with the benefits and risks for these drugs, including higher risk for cardiac events and malignancy; however, one adverse effect may be overlooked, especially by specialties outside of dermatology: acne. Though less serious than some other side effects, JAK inhibitor–associated acne — JAKne, for short — can be a concern for patients.

“Your physical appearance and how you present yourself to the world is an important part of your self-confidence and living life on your own terms,” said Arash Mostaghimi, MD, the director of inpatient dermatology at Brigham and Women’s Hospital in Boston, Massachusetts. “I think letting people know about [JAKne] and then addressing it when it occurs should be a normal part of managing these medications.”
 

What Is JAKne?

JAKne generally looks like other kinds of acne, explained Janelle Nassim, MD, director of laser and cosmetic dermatology at the Indiana University School of Medicine, Indianapolis. “It can affect the same areas that typical acne affects, including the face, chest, back, neck, and upper shoulders.”

Though it appears like typical forms of acne, it is not clear what drives these skin eruptions in patients taking JAK inhibitors.

“We don’t understand the underlying pathophysiology,” Dr. Mostaghimi said. “It looks like acne, but we don’t know if the exact underlying inflammatory process is the same or if it’s different.”

In a 2023 systematic review of clinical studies, Dr. Mostaghimi and colleagues found that patients on any JAK inhibitor were nearly four times more likely to experience acne than patients who received placebo, but risk varied between medications. Patients taking JAK inhibitors for skin conditions had higher risk for acne than those given the medications for other indications. However, Dr. Mostaghimi thinks this finding is the result of selection bias.

Participants may not mention side effects like acne in trials for rheumatologic or gastrointestinal conditions, he said, unlike in trials for skin conditions. “Clinically, I’ve seen it in patients across every indication.”

Patients with a history of acne seem to be more likely to develop this side effect, though formal studies looking into risk factors are lacking. In Dr. Mostaghimi’s own clinical experience, JAKne is also more common in younger patients, but it can happen to anyone. “I’ve seen 70-year-olds develop acne — patients who’ve never had an issue their whole life — when they’re taking a JAK inhibitor.”

This issue also appears to be more common earlier in treatment, he added, and may improve over time as a patient continues with the medication.
 

How Do You Treat It?

“I think in other specialties, you will often feel awkward addressing skin conditions or pointing out acne,” Dr. Mostaghimi said. The most important steps are being aware of this potential side effect, and if you see it practice, to bring it up.

“Say: I’m noticing there’s some changes in your skin. Some patients on JAK inhibitors develop more acne. Have you noticed this? And if so, is this bothering you?”

Generally, JAKne is mild to moderate, explained Dr. Nassim, and if non-dermatologists are comfortable, they can prescribe a first-line topical regimen for patients. Dr. Mostaghimi recommends prescribing a clindamycin 1% lotion or gel. In addition, patients can use a benzoyl peroxide wash (4% or 10%) combined with a gentle retinoid, such as adapalene.

In patients with scalp or hairline involvement, he often prescribes a ketoconazole 2% shampoo, which patients can use to wash their scalp, face, chest, and back in the shower.

If they aren’t responding to these initial treatments, then refer to a dermatologist for further assessment.

“Ultimately, referring to a dermatologist is the best course of action,” Dr. Nassim said. “I have had patients on JAK inhibitors who improved with topical acne treatments, and some that required more aggressive treatment with oral medications.”

Dr. Mostaghimi reported consulting fees from AbbVie, Concert Pharmaceuticals, Pfizer, and 3Derm Systems; research funding from Incyte, Aclaris Therapeutics, Eli Lilly, and Concert Pharmaceuticals; personal fees from Equillium, ASLAN Pharmaceuticals, ACOM, and Boehringer Ingelheim; and advisory board fees from Fig.1 Beauty, Eli Lilly, Pfizer, and Hims & Hers Health. Dr. Nassim had no relevant disclosures.

Since the first Food and Drug Administration approval of a Janus kinase (JAK) inhibitor in 2011, the number of these medications available — and their treatment indications — have continued to grow. Prescribing physicians are familiar with the benefits and risks for these drugs, including higher risk for cardiac events and malignancy; however, one adverse effect may be overlooked, especially by specialties outside of dermatology: acne. Though less serious than some other side effects, JAK inhibitor–associated acne — JAKne, for short — can be a concern for patients.

“Your physical appearance and how you present yourself to the world is an important part of your self-confidence and living life on your own terms,” said Arash Mostaghimi, MD, the director of inpatient dermatology at Brigham and Women’s Hospital in Boston, Massachusetts. “I think letting people know about [JAKne] and then addressing it when it occurs should be a normal part of managing these medications.”
 

What Is JAKne?

JAKne generally looks like other kinds of acne, explained Janelle Nassim, MD, director of laser and cosmetic dermatology at the Indiana University School of Medicine, Indianapolis. “It can affect the same areas that typical acne affects, including the face, chest, back, neck, and upper shoulders.”

Though it appears like typical forms of acne, it is not clear what drives these skin eruptions in patients taking JAK inhibitors.

“We don’t understand the underlying pathophysiology,” Dr. Mostaghimi said. “It looks like acne, but we don’t know if the exact underlying inflammatory process is the same or if it’s different.”

In a 2023 systematic review of clinical studies, Dr. Mostaghimi and colleagues found that patients on any JAK inhibitor were nearly four times more likely to experience acne than patients who received placebo, but risk varied between medications. Patients taking JAK inhibitors for skin conditions had higher risk for acne than those given the medications for other indications. However, Dr. Mostaghimi thinks this finding is the result of selection bias.

Participants may not mention side effects like acne in trials for rheumatologic or gastrointestinal conditions, he said, unlike in trials for skin conditions. “Clinically, I’ve seen it in patients across every indication.”

Patients with a history of acne seem to be more likely to develop this side effect, though formal studies looking into risk factors are lacking. In Dr. Mostaghimi’s own clinical experience, JAKne is also more common in younger patients, but it can happen to anyone. “I’ve seen 70-year-olds develop acne — patients who’ve never had an issue their whole life — when they’re taking a JAK inhibitor.”

This issue also appears to be more common earlier in treatment, he added, and may improve over time as a patient continues with the medication.
 

How Do You Treat It?

“I think in other specialties, you will often feel awkward addressing skin conditions or pointing out acne,” Dr. Mostaghimi said. The most important steps are being aware of this potential side effect, and if you see it practice, to bring it up.

“Say: I’m noticing there’s some changes in your skin. Some patients on JAK inhibitors develop more acne. Have you noticed this? And if so, is this bothering you?”

Generally, JAKne is mild to moderate, explained Dr. Nassim, and if non-dermatologists are comfortable, they can prescribe a first-line topical regimen for patients. Dr. Mostaghimi recommends prescribing a clindamycin 1% lotion or gel. In addition, patients can use a benzoyl peroxide wash (4% or 10%) combined with a gentle retinoid, such as adapalene.

Biotech startups worldwide are rushing to market screening tests that they claim can detect various cancers in early stages with just a few drops of blood. The tests allegedly will simplify cancer care by eliminating tedious scans, scopes, and swabs at the doctor’s office. 

The promise of these early detection tests is truly “enticing,” Hilary A. Robbins, PhD, from the International Agency for Research on Cancer of the World Health Organization in Lyon, France, said in an interview.

In an opinion article in The New England Journal of Medicine, she emphasized that the new cancer tests are much less cumbersome than traditional screening strategies for individual cancers. Moreover, they could enable the early detection of dozens of cancer types for which no screening has been available so far.
 

Meeting the Criteria

The problem is that these tests have not met the strict criteria typically required for traditional cancer screening tests. To be considered for introduction as a screening procedure, a test usually needs to meet the following four minimum requirements:

• The disease that the test screens for must have a presymptomatic form.
• The screening test must be able to identify this presymptomatic disease.
• Treating the disease in the presymptomatic phase improves prognosis (specifically, it affects cancer-specific mortality in a randomized controlled trial).
• The screening test is feasible, and the benefits outweigh potential risks.

“The new blood tests for multiple cancers have so far only met the second criteria, showing they can detect presymptomatic cancer,” Dr. Robbins wrote.

The next step would be to demonstrate that they affect cancer-specific mortality. “But currently, commercial interests seem to be influencing the evidence standards for these cancer tests,” said Dr. Robbins.
 

Inappropriate Endpoints?

Some proponents of such tests argue that, unlike for previous cancer screening procedures, initial approval should not depend on the endpoint of cancer-specific mortality. It would take too long to gather sufficient outcome data, and in the meantime, people would die, they argue.

Eric A. Klein, MD, from the Glickman Urological and Kidney Institute in Cleveland, Ohio, and colleagues advocate for alternative endpoints such as the incidence of late-stage cancer in an article published in Cancer Epidemiology, Biomarkers & Prevention.

“The concept would be,” they wrote, “that a negative signal would not indicate a mortality benefit, leading to the study being stopped. A positive signal, on the other hand, could result in provisional approval until mortality data and real-world evidence of effectiveness are available. This would resemble the accelerated approval of new cancer drugs, which often is based on progression-free survival until there postmarketing data on overall survival emerge.”

Dr. Klein is also employed at the US biotech start-up Grail, which developed the Galleri test, which is one of the best-known and most advanced cancer screening tests. The Galleri test uses cell-free DNA and machine learning to detect a common cancer signal in more than 50 cancer types and predict the origin of the cancer signal. Consumers in the United States can already order and perform the test.
 

An NHS Study

Arguments for different endpoints apparently resonated with the United Kingdom’s National Health Service (NHS). Three years ago, they initiated the Galleri study, a large randomized controlled trial to assess the effectiveness of Grail’s cancer test. The primary endpoint was not cancer-specific mortality, but the incidence of stage III or IV cancer.

The results are expected in 2026. But recruitment was stopped after 140,000 participants were enrolled. The NHS reported that the initial results were not convincing enough to continue the trial. Exact numbers were not disclosed.

The Galleri study deviates from the standard randomized controlled trial design for cancer screening procedures not only in terms of the primary endpoint, but also in blinding. The only participants who were unblinded and informed of their test results are those in the intervention group with a positive cancer test.
 

False Security

This trial design encourages participants to undergo blood tests once per year. But according to Dr. Robbins, it prevents the exploration of the phenomenon of “false security,” which is a potential drawback of the new cancer tests.

“Women with a negative mammogram can reasonably assume that they probably do not have breast cancer. But individuals with a negative cancer blood test could mistakenly believe they cannot have any cancer at all. As a result, they may not undergo standard early detection screenings or seek medical help early enough for potential cancer symptoms,” said Dr. Robbins.

To assess the actual risk-benefit ratio of the Galleri test, participants must receive their test results, she said. “Under real-world conditions, benefits and risks can come from positive and negative results.” 
 

Upcoming Trial

More illuminating results may come from a large trial planned by the National Cancer Institute in the United States. Several new cancer tests will be evaluated for their ability to reduce cancer-specific mortality. A pilot phase will start later in 2024. “This study may be the only one with sufficient statistical power to determine whether an approach based on these cancer tests can reduce cancer-specific mortality,” said Dr. Robbins.

For the new blood tests for multiple cancers, it is crucial that health authorities “set a high bar for a benefit,” she said. This, according to her, also means that they must show an effect on cancer-specific mortality before being introduced. “This evidence must come from studies in which commercial interests do not influence the design, execution, data management, or data analysis.”

Jeffrey S. Weber, MD, PhD, the 2016 winner of the Giants of Cancer Care award in melanoma and a valued contributor to Medscape Oncology, has died.

Dr. Weber, a melanoma and cancer immunotherapy specialist, served as deputy director of the Laura and Isaac Perlmutter Cancer Center at New York University (NYU) Langone Medical Center in New York City. He also held positions as the Laura and Isaac Perlmutter Professor of Oncology in the Department of Medicine at the NYU Grossman School of Medicine, director of the Experimental Therapeutics Program, and co-leader of the Clinical Melanoma Program Board at NYU Langone Health.

Dr. Weber was a principal investigator on many studies, including pivotal clinical drug trials in melanoma and trials focused on managing autoimmune side effects from immunotherapy. He published more than 150 articles in top peer-reviewed journals.

For many years, Dr. Weber hosted the popular “Weber on Oncology” series of video contributions for Medscape Oncology, sharing updates and insights on noteworthy research and breakthroughs in melanoma.

“The Melanoma Research Alliance mourns the passing of Dr. Jeffrey S. Weber, a true pioneer in the field of cancer immunotherapy and an extraordinary leader in melanoma research. His contributions have forever changed the landscape of melanoma treatment, bringing groundbreaking advances from the lab into clinical practice and offering hope to countless patients,” the Melanoma Research Alliance posted on LinkedIn. 

Many X users also shared condolences and memories of Dr. Weber, praising his numerous contributions and accomplishments. 

“[Cancer Research Institute] mourns the loss of Dr. Jeffrey S. Weber ... [a]s an accomplished physician scientist, Dr. Weber drove advances in melanoma research, and played an active role in educating patients about the lifesaving power of immunotherapy,” the Cancer Research Institute posted.

A colleague noted that “[h]e was involved in the early days of cytokine and cell therapy and most recently led studies of personalized vaccines for melanoma patients. ... He was a great friend and colleague to many of us in the melanoma and immunotherapy field and we will remember him as a pioneer, thought leader and compassionate physician.”

As more data show potentially dangerous effects of climate and weather on individuals with chronic medical conditions, CVS Health has introduced an initiative that uses technology to provide weather alerts and targeted outreach to those at increased risk, according to a press release from the company. Ultimately, the goals of the initiative are to improve health, reduce emergency department visits, hospital stays, and medical costs, according to the press release.

Extreme weather events such as heat waves are becoming more frequent and severe, but most heat-related deaths are preventable with outreach and intervention, Dan Knecht, MD, vice president and chief clinical innovation officer for CVS Caremark, a division of CVS Health, said in an interview. The approach will combine the company’s services, including care managers, health centers, and data, to aid patients vulnerable to severe weather.

The initiative is starting with a focus on extreme heat events and will expand this fall with alerts about high levels of air pollution for individuals with vulnerability to reduced lung function, asthma, and cardiac problems as a result of exposure to high air-pollution levels, according to Dr. Knecht.

For now, the initiative is available to members of Aetna Medicare, according to Dr. Knecht. “Our goal is to expand to other consumers, including those who visit MinuteClinic and CVS Pharmacy locations, where we can provide timely environment-related recommendations at time of care,” he said.

The alert system uses environmental data analytics to pair highly localized forecasts and real-time insights about air quality, wildfires, and high heat with medical and pharmacy data for high-risk patients in areas affected by extreme weather.

For example, for individuals who are at risk and living in areas facing extreme heat, “registered nurse care managers proactively reach out to vulnerable patients up to several days in advance of an extreme weather event and provide them personalized tips and resources,” said Dr. Knecht.

In addition, he added, “we talk to patients about how to manage their medications during periods of extreme heat and, when delivering medications, take weather data into account to determine appropriate packaging materials for shipments.”

These interventions direct patients to CVS Health–linked resources, such as Oak Street Health clinics available as cooling centers, health services provided at MinuteClinic locations, and medication management at CVS pharmacies. Other interventions include virtual or in-person mental health counseling through MinuteClinic.

Dr. Knecht offered additional guidance for clinicians and patients to help manage heat waves. “Heat and certain medications can impair heat tolerance and the ability to regulate body temperature,” he told this news organization. Extreme heat may affect the performance of some medications and their devices, such as inhalers and diabetes supplies, he added.
 

Health Alerts Have Potential, But Comprehensive Approach is Needed

“Patients with chronic lung conditions are highly susceptible to the impact of climate change,” MeiLan K. Han, MD, a pulmonologist and professor of internal medicine at the University of Michigan, Ann Arbor, said in an interview. “Increasing dust, hotter temperatures, and higher levels of air pollution make it more difficult for patients to breathe,” she said. Data also suggest that higher levels of air pollution may not only cause chronic lung disease but also cause worsening symptoms among those with existing disease, she added.

A weather-related health alert could be useful for patients so they can be prepared, Dr. Han told this news organization.

“For a patient with chronic lung disease, a hot weather alert may mean that it will be harder for patients to breathe, and [they] may [be] more susceptible to heat stroke and dehydration if they do not have access to air conditioning,” she said. “At a minimum, patients should ensure they are on their controller medications, which often means a daily inhaler for patients with conditions such as asthma and chronic obstructive pulmonary disease (COPD). However, patients also should have access to their short-term reliever medications so they can be prepared for increased shortness of breath that may accompany a hot weather day,” Dr. Han explained.

However, not all patients have access to technology such as smartphones or other devices that will alert them to impending weather events, such as heat waves, said Dr. Han. “For these patients, a standard phone call may be beneficial,” she said.

Looking ahead, “programs for weather-related health alerts will need to be comprehensive, focusing not only on access to needed medications but also climate-controlled settings for temporary relief of heat,” said Dr. Han. “For some of our most vulnerable patients, while they may have air conditioning, they may not be able to afford to run it, so this needs to be considered in developing a comprehensive program,” she emphasized.

As more data show potentially dangerous effects of climate and weather on individuals with chronic medical conditions, CVS Health has introduced an initiative that uses technology to provide weather alerts and targeted outreach to those at increased risk, according to a press release from the company. Ultimately, the goals of the initiative are to improve health, reduce emergency department visits, hospital stays, and medical costs, according to the press release.

Extreme weather events such as heat waves are becoming more frequent and severe, but most heat-related deaths are preventable with outreach and intervention, Dan Knecht, MD, vice president and chief clinical innovation officer for CVS Caremark, a division of CVS Health, said in an interview. The approach will combine the company’s services, including care managers, health centers, and data, to aid patients vulnerable to severe weather.

The initiative is starting with a focus on extreme heat events and will expand this fall with alerts about high levels of air pollution for individuals with vulnerability to reduced lung function, asthma, and cardiac problems as a result of exposure to high air-pollution levels, according to Dr. Knecht.

For now, the initiative is available to members of Aetna Medicare, according to Dr. Knecht. “Our goal is to expand to other consumers, including those who visit MinuteClinic and CVS Pharmacy locations, where we can provide timely environment-related recommendations at time of care,” he said.

The alert system uses environmental data analytics to pair highly localized forecasts and real-time insights about air quality, wildfires, and high heat with medical and pharmacy data for high-risk patients in areas affected by extreme weather.

For example, for individuals who are at risk and living in areas facing extreme heat, “registered nurse care managers proactively reach out to vulnerable patients up to several days in advance of an extreme weather event and provide them personalized tips and resources,” said Dr. Knecht.

In addition, he added, “we talk to patients about how to manage their medications during periods of extreme heat and, when delivering medications, take weather data into account to determine appropriate packaging materials for shipments.”

These interventions direct patients to CVS Health–linked resources, such as Oak Street Health clinics available as cooling centers, health services provided at MinuteClinic locations, and medication management at CVS pharmacies. Other interventions include virtual or in-person mental health counseling through MinuteClinic.

Dr. Knecht offered additional guidance for clinicians and patients to help manage heat waves. “Heat and certain medications can impair heat tolerance and the ability to regulate body temperature,” he told this news organization. Extreme heat may affect the performance of some medications and their devices, such as inhalers and diabetes supplies, he added.

Having an ostomy is a dreaded prospect for many patients with rectal cancer.

To defer, and potentially avoid, this life-altering surgery, the watch-and-wait approach has become increasingly common among patients with locally advanced disease who have a complete response to neoadjuvant chemoradiation.

About 80% of these patients who have a complete clinical response — a perfectly healed scar where the tumor used to be and other favorable features — can forgo total mesorectal excision and preserve their rectum.

The success of watch-and-wait among complete responders has led some centers to offer the approach in patients with near-complete responses to neoadjuvant chemoradiation.

But watch-and-wait for near-complete clinical responders “is very controversial,” Alan P. Venook, MD, a gastrointestinal oncologist at the University of California, San Francisco (UCSF), told this news organization.

“You sure as hell don’t want to miss a chance to cure a patient,” Dr. Venook said.

A near-complete clinical response essentially means there is no sign of the tumor 8 weeks after total neoadjuvant therapy, but the tumor bed hasn’t completely healed.

The goal of watch-and-wait in this scenario is to give near-complete response lesions time to become complete responses.

But there’s no clear way to predict which tumors will evolve into a clinical complete response.

Recent studies evaluating the conversion rate have reported that anywhere from 39% to about 90% of near-complete responders became complete responders. Some of the variation likely comes down to differences in the clinical stage of patients evaluated in each study as well as the limited number of patients who achieve a near-complete response overall.

Other concerns have emerged that waiting for near-complete responses to become complete leaves extra time for some tumors to metastasize and that tumor regrowth is much higher compared with complete responders.

A recent study found that 13% of near-complete responders who preserved their rectum on watch-and-wait developed distant metastases vs about 5% of long-term complete responders. The study also found that just over half of near-complete responders have tumor regrowth compared with about one in five complete responders.

But even with regrowth, “surgery is still curative,” explained Julio Garcia-Aguilar, MD, PhD, a pioneer of watch-and-wait for rectal cancer.

And overall, around 50%-60% of patients with a near-complete response can avoid surgery and preserve their rectum.
 

Selecting Patients for Watch-and-Wait

The key to deciding which patients are right for watch-and-wait is to understand how a near-complete clinical response was defined in the OPRA trial, a landmark randomized trial led by Dr. Garcia-Aguilar that helped establish watch-and-wait as an option in rectal cancer.

OPRA defined a near-complete response as no visible tumor but, in the tumor bed, mild erythema, superficial ulceration, minor mucosal abnormality or small nodules, and an irregular mucosa. The criteria also included no palpable tumor with smooth induration or a minor mucosal abnormality on the digital rectal exam.

The National Comprehensive Cancer Network mirrored the definition when, for the first time, it recommended watch-and-wait as an option for near-complete response in its 2023 rectal cancer guidelines. The group also added a few MRI requirements.

UCSF offers the watch-and-wait option to some patients with near-complete responses, but each decision is made on a case-by-case basis by a tumor board considering numerous measures of tumor aggressiveness.

Even then, “we have, in many cases, struggled to figure out what the right choices are,” Dr. Venook said.

For those chosen for watch-and-wait, Dr. Venook noted that UCSF has top-notch surgeons, radiation oncologists, medical oncologists, and pathologists who have the resources to follow patients closely.

For community practices without the resources of a major cancer center, watch-and-wait for near-complete response to rectal cancer “is really asking a lot,” Dr. Venook said.

Dr. Garcia-Aguilar, a colorectal surgeon at Memorial Sloan Kettering Cancer Center in New York City, explained that after years of studying the issue, he is comfortable with watch-and-wait in near-complete responders as long as it’s done carefully and in patients who will comply with ongoing surveillance.

Dr. Garcia-Aguilar explained that, after diagnosing a near-complete response 8 weeks following total neoadjuvant therapy, the patient needs to come back 6 weeks later. At that point, it’s time to assess whether that near-complete response is evolving into a complete response or not evolving into a complete response.

If it’s evolving into a complete response, surveillance continues about every 8 weeks, but if the tumor has stopped responding, “you take [the patient] to the operating room,” Dr. Garcia-Aguilar said.

As for the bigger safety concern — that near clinical complete response tumors will metastasize — Dr. Garcia-Aguilar’s opinion is that micrometastases are probably already there when the rectal cancer is first diagnosed and will manifest themselves “no matter what happens to the primary tumor.”

Because of that, he noted, “I don’t think the risk is very high” when surgery is delayed a few months to give near-complete response patients a chance to keep their rectum.

The way to answer the metastasis question is to do a randomized trial pitting surgery against watch-and-wait in patients with near-clinical complete response rectal cancer.

However, Dr. Garcia-Aguilar doesn’t think that trial will ever happen. Patients won’t allow themselves to be randomized to surgery once they find out they might be able to avoid a permanent ostomy, he said.

Dr. Venook had no disclosures. Dr. Garcia-Aguilar reported personal fees from Medtronic, Johnson & Johnson, and Intuitive Surgical.

STOCKHOLM — At the American Society of Retina Specialists (ASRS) 2024 Annual Meeting, researchers discussed how insights into potential risk factors and new treatments could improve outcomes for patients with diabetic retinopathy.

Jennifer Lim, MD, an ophthalmologist and director of the Retina Service at the University of Illinois Hospital & Health Sciences System in Chicago, told this news organization that emerging approaches to treating diabetic retinopathy offer hope because they address the root causes of the disease beyond just targeting vascular endothelial growth factor (VEGF). She said innovative methods and add-on treatments could lead to more durable and effective drugs.

Exploration of risk factors and treatment options for diabetic retinopathy could lead to more effective management strategies for the condition, agreed David Boyer, MD, an ophthalmologist at Retina Vitreous Associates Medical Group in Los Angeles, speaking with this news organization.
 

Risk Factors for Diabetic Retinopathy

Sodium-glucose cotransporter 2 (SGLT2) inhibitors and glucagon-like peptide 1 receptor agonists (GLP-1 RAs) have gained popularity because of their benefits beyond glycemic control, including weight loss, and cardiovascular and kidney protection. However, the impact of these medications on vision-threatening retinal complications is not fully understood. “There has always been a question about whether these newer diabetes medications might exacerbate diabetic eye disease,” said Dr. Boyer.

In a retrospective observational study, researchers included adults with type 2 diabetes and moderate cardiovascular disease risk who had no history of advanced diabetic retinal complications. These patients initiated treatment with GLP-1 RA, SGLT2 inhibitors, DPP-4 inhibitors, or sulfonylureas. The study used inverse probability of treatment weighting to mimic randomization and compared the time to the first treatment for diabetic macular edema or proliferative diabetic retinopathy across the treatment groups.

Results, presented by Andrew J. Barkmeier, MD, an associate professor of ophthalmology at the Mayo Clinic, showed that among 371,698 patients, those who initiated therapy with SGLT2 inhibitors had a lower risk of requiring treatment for sight-threatening retinopathy compared with those using other medication classes. GLP-1 RA did not increase retinopathy risk relative to dipeptidyl peptidase 4 inhibitors and sulfonylurea medications.

“[This study] told us that we do have to keep an eye on patients’ retinopathy when they start on these new inhibitors. But the progression is minimal and, overall, I think most people today favor keeping blood sugar levels as good as possible,” said Dr. Boyer, who was not involved in the study.

Another factor that might increase diabetic retinopathy progression is obstructive sleep apnea. This underdiagnosed condition is linked to several health issues, including dementia, stroke, and myocardial infarctions. Although not easily treated, obstructive sleep apnea is manageable, Dr. Boyer explained.

Researchers utilized the TriNetX electronic health records research network to identify patients with nonproliferative diabetic retinopathy, both with and without obstructive sleep apnea. 

The results, presented by Ehsan Rahimy, MD, a retinal specialist at Palo Alto Medical Foundation and a professor at Stanford University, showed that patients with obstructive sleep apnea had a significantly higher risk of progressing to proliferative diabetic retinopathy and developing new-onset diabetic macular edema. These patients were more likely to require ocular interventions, such as intravitreal injections and laser photocoagulation. They also had greater risks for stroke, myocardial infarction, and death compared with those who did not have obstructive sleep apnea.

“It was good to bring this to everybody’s attention,” said Dr. Boyer, who was not involved in the study. “It’s an easy question to ask someone if they snore.”
 

New Treatments on the Horizon

In another presentation, Nathan C. Steinle, MD, of California Retina Consultants, presented a study that assessed the durability of response to sozinibercept in patients with retinal vascular diseases. This novel therapeutic agent is designed to inhibit VEGF-C and VEGF-D in conditions where VEGF-A suppression alone is insufficient. 

Sozinibercept was combined with standard anti–VEGF-A therapies such as ranibizumab or aflibercept. It involved a prospective, post hoc analysis of two phase 1b, open-label, dose-escalation studies, including 40 patients with neovascular age-related macular degeneration (nAMD; 31 patients) or diabetic macular edema (nine patients). These patients, either treatment-naive or previously treated, received three intravitreal injections of ranibizumab or aflibercept in combination with sozinibercept at various doses.

Results indicated that sozinibercept combination therapy was well tolerated, with no dose-limiting toxicities. In treatment-naive nAMD patients, the mean best-corrected visual acuity (BCVA) improved significantly from baseline at months 3 and 6. Previously treated nAMD patients also showed BCVA improvements, although to a lesser extent. For patients with persistent diabetic macular edema, switching to sozinibercept plus aflibercept resulted in notable BCVA gains. The mean time to requiring retreatment was longer in treatment-naive patients than in those previously treated, indicating a durable response. 

“Combination therapy with sozinibercept is going to be really important,” said Dr. Lim, who was not involved in the study, “because it attacks with a dual mechanism of action.”

Oral agents promise a potentially easier alternative for patients compared with frequent injections. CU06-1004 is a novel orally administered endothelial dysfunction blocker that has shown promise in stabilizing damaged capillaries, reducing abnormal angiogenesis, and inhibiting inflammatory activation in preclinical studies. “CU06 is very interesting to me because by preventing endothelial loss, it gets to the pathophysiology of why the blood vessels break down,” Dr. Lim said.

In a proof-of-concept phase 2a, multicenter, open-label, parallel-group trial, investigators randomly assigned 67 patients with diabetic macular edema to receive 100 mg, 200 mg, or 300 mg of CU06-1004 once daily for 12 weeks, followed by a 4-week follow-up. 

Results presented by Victor Gonzalez, MD, of Valley Retina Institute in Texas, indicated that the oral agent improved BCVA, stabilized central subfield thickness, and showed positive anatomical changes in optical coherence tomography images. CU06-1004 was well tolerated, with no drug-related serious adverse events. 

“The number [of patients] was very small, and we will need a much longer, larger trial to see if [CU06-1004] has benefits long term,” said Dr. Boyer, who was not involved in the study. “But I think we’re all very excited if we can find an oral agent for treating diabetic retinopathy. It would be easier for the patient to take a pill than having to come in for injections.” 

The sustained-release axitinib implant, OTX-TKI, is also generating significant interest, particularly for nonproliferative diabetic retinopathy. Axitinib, a tyrosine kinase inhibitor (TKI), targets signaling pathways crucial in cellular processes, providing a novel approach to managing diseases where traditional therapies might fall short. Unlike traditional anti-VEGF treatments that focus solely on cytokine levels, TKIs block the activation of signaling pathways, preventing downstream signaling regardless of cytokine levels. This mechanism is particularly important because it effectively inhibits disease progression even if levels of VEGF are high, Dr. Lim explained.

In the phase 1 HELIOS trial, OTX-TKI was assessed in patients with nonproliferative diabetic retinopathy. This multicenter, double-masked, parallel-group clinical study included 21 patients who had not received anti-VEGF treatment, dexamethasone intravitreal implants in the previous 12 months, or intraocular steroid injections in the prior 4 months. Patients were randomly assigned to receive either OTX-TKI or sham treatment.

Results presented by Dilsher S. Dhoot, MD, of California Retina Consultants, indicated that OTX-TKI was generally well tolerated, with no serious ocular adverse events. At 48 weeks, 46.2% of eyes treated with OTX-TKI showed a 1- or 2-step improvement on the Diabetic Retinopathy Severity Scale (DRSS) compared with none in the sham arm. Additionally, no eyes treated with OTX-TKI experienced a worsening on the DRSS, whereas 25% of eyes in the sham arm did. Vision-threatening complications, such as proliferative diabetic retinopathy or diabetic macular edema, developed in 37.5% of the sham group but in none of the OTX-TKI treated eyes. A single injection of OTX-TKI provided durable DRSS improvement for up to 48 weeks, with no patients in either arm requiring rescue therapy.

“This is a really exciting add-on treatment,” Dr. Lim said, who was not involved in the study. She explained that it is initially necessary to control the disease with standard treatments, because TKIs may take longer to exhibit their effects. Once the disease is stabilized, TKIs can be used alongside other therapies, potentially reducing the reliance on frequent anti-VEGF injections. “These are preliminary results, but that’s the hope going forward.”

STOCKHOLM — At the American Society of Retina Specialists (ASRS) 2024 Annual Meeting, researchers discussed how insights into potential risk factors and new treatments could improve outcomes for patients with diabetic retinopathy.

Jennifer Lim, MD, an ophthalmologist and director of the Retina Service at the University of Illinois Hospital & Health Sciences System in Chicago, told this news organization that emerging approaches to treating diabetic retinopathy offer hope because they address the root causes of the disease beyond just targeting vascular endothelial growth factor (VEGF). She said innovative methods and add-on treatments could lead to more durable and effective drugs.

Exploration of risk factors and treatment options for diabetic retinopathy could lead to more effective management strategies for the condition, agreed David Boyer, MD, an ophthalmologist at Retina Vitreous Associates Medical Group in Los Angeles, speaking with this news organization.
 

Risk Factors for Diabetic Retinopathy

Sodium-glucose cotransporter 2 (SGLT2) inhibitors and glucagon-like peptide 1 receptor agonists (GLP-1 RAs) have gained popularity because of their benefits beyond glycemic control, including weight loss, and cardiovascular and kidney protection. However, the impact of these medications on vision-threatening retinal complications is not fully understood. “There has always been a question about whether these newer diabetes medications might exacerbate diabetic eye disease,” said Dr. Boyer.

In a retrospective observational study, researchers included adults with type 2 diabetes and moderate cardiovascular disease risk who had no history of advanced diabetic retinal complications. These patients initiated treatment with GLP-1 RA, SGLT2 inhibitors, DPP-4 inhibitors, or sulfonylureas. The study used inverse probability of treatment weighting to mimic randomization and compared the time to the first treatment for diabetic macular edema or proliferative diabetic retinopathy across the treatment groups.

Results, presented by Andrew J. Barkmeier, MD, an associate professor of ophthalmology at the Mayo Clinic, showed that among 371,698 patients, those who initiated therapy with SGLT2 inhibitors had a lower risk of requiring treatment for sight-threatening retinopathy compared with those using other medication classes. GLP-1 RA did not increase retinopathy risk relative to dipeptidyl peptidase 4 inhibitors and sulfonylurea medications.

“[This study] told us that we do have to keep an eye on patients’ retinopathy when they start on these new inhibitors. But the progression is minimal and, overall, I think most people today favor keeping blood sugar levels as good as possible,” said Dr. Boyer, who was not involved in the study.

Another factor that might increase diabetic retinopathy progression is obstructive sleep apnea. This underdiagnosed condition is linked to several health issues, including dementia, stroke, and myocardial infarctions. Although not easily treated, obstructive sleep apnea is manageable, Dr. Boyer explained.

Researchers utilized the TriNetX electronic health records research network to identify patients with nonproliferative diabetic retinopathy, both with and without obstructive sleep apnea. 

The results, presented by Ehsan Rahimy, MD, a retinal specialist at Palo Alto Medical Foundation and a professor at Stanford University, showed that patients with obstructive sleep apnea had a significantly higher risk of progressing to proliferative diabetic retinopathy and developing new-onset diabetic macular edema. These patients were more likely to require ocular interventions, such as intravitreal injections and laser photocoagulation. They also had greater risks for stroke, myocardial infarction, and death compared with those who did not have obstructive sleep apnea.

“It was good to bring this to everybody’s attention,” said Dr. Boyer, who was not involved in the study. “It’s an easy question to ask someone if they snore.”
 

New Treatments on the Horizon

In another presentation, Nathan C. Steinle, MD, of California Retina Consultants, presented a study that assessed the durability of response to sozinibercept in patients with retinal vascular diseases. This novel therapeutic agent is designed to inhibit VEGF-C and VEGF-D in conditions where VEGF-A suppression alone is insufficient. 

Sozinibercept was combined with standard anti–VEGF-A therapies such as ranibizumab or aflibercept. It involved a prospective, post hoc analysis of two phase 1b, open-label, dose-escalation studies, including 40 patients with neovascular age-related macular degeneration (nAMD; 31 patients) or diabetic macular edema (nine patients). These patients, either treatment-naive or previously treated, received three intravitreal injections of ranibizumab or aflibercept in combination with sozinibercept at various doses.

Results indicated that sozinibercept combination therapy was well tolerated, with no dose-limiting toxicities. In treatment-naive nAMD patients, the mean best-corrected visual acuity (BCVA) improved significantly from baseline at months 3 and 6. Previously treated nAMD patients also showed BCVA improvements, although to a lesser extent. For patients with persistent diabetic macular edema, switching to sozinibercept plus aflibercept resulted in notable BCVA gains. The mean time to requiring retreatment was longer in treatment-naive patients than in those previously treated, indicating a durable response. 

“Combination therapy with sozinibercept is going to be really important,” said Dr. Lim, who was not involved in the study, “because it attacks with a dual mechanism of action.”

Oral agents promise a potentially easier alternative for patients compared with frequent injections. CU06-1004 is a novel orally administered endothelial dysfunction blocker that has shown promise in stabilizing damaged capillaries, reducing abnormal angiogenesis, and inhibiting inflammatory activation in preclinical studies. “CU06 is very interesting to me because by preventing endothelial loss, it gets to the pathophysiology of why the blood vessels break down,” Dr. Lim said.

Emerging diagnostic technology that uses artificial intelligence (AI) has demonstrated the potential to free dermatologists from the burden of triaging skin lesions, but dermatology lags behind some other specialties in harnessing the power of AI, and confusion surrounds dermatologists’ role in using this technology, according to researchers and dermatologists investigating AI.

While some AI-integrated devices designed to triage skin lesions have emerged, including one that received Food and Drug Administration (FDA) clearance earlier in 2024, it may be some time before AI has a meaningful clinical impact in dermatology and, more specifically, the diagnosis of skin cancer, Ivy Lee, MD, a dermatologist in Pasadena, California, and chair of the American Academy of Dermatology’s augmented intelligence committee, told this news organization.

“It hasn’t really translated into clinical practice yet,” Dr. Lee said of AI in dermatology. “There have been significant advances in terms of the technical possibility and feasibility of these tools, but the translation and integration of AI into actual clinical work flows to benefit patients beyond academic research studies has been limited.” More studies and more “easily accessible and digestible information” are needed to evaluate AI tools in dermatologic practice.

“In dermatology, we’re on a cusp with AI,” said Rebecca Hartman, MD, MPH, chief of dermatology at the VA Boston Healthcare System and director of melanoma epidemiology at Brigham and Women’s Hospital, Boston, Massachusetts. “I think it’s going to come and change what we do,” which is especially true for any image-based specialty,” including radiology and pathology, in addition to dermatology.

Dr. Hartman led a study of one of these emerging technologies, the handheld elastic scattering spectroscopy device DermaSensor, which was cleared by the FDA in January for evaluating skin lesions suggestive of skin cancer.
 

Early AI Devices for Skin Cancer Detection

At the American Society for Laser Medicine and Surgery (ASLMS) meeting in April, a panel explored a number of algorithms with dermatologic applications that use AI to triage skin lesions, including DermaSensor.

Raman spectroscopy, which contains a handheld Raman probe, a diode laser, and a detecting spectrograph. A laser beam — which at 1.56 W/cm² is below the maximum permissible exposure — focuses on the skin target with a 3.5-mm spot, gathers data on the target, and feeds it back into the unit that houses the algorithm that evaluates the spot analysis. It’s still in the investigative phase. A clinical trial, published almost 5 years ago, demonstrated a sensitivity of 90%-99% and a specificity of 24%-66% for skin cancer.

A dermatoscope called Sklip clips onto a smartphone and performs what company cofounder Alexander Witkowski, MD, PhD, described as an “optical painless virtual biopsy” for at-home use. The device uploads the captured image to an AI platform for analysis. It received FDA breakthrough device designation in 2022. At the ASLMS meeting, Dr. Witkowski said that clinical performance showed the device had a 97% sensitivity and 30% specificity for skin cancer.

DermaSensor, described in the study conducted by Dr. Hartman and others as a noninvasive, point-and-click spectrometer, is a wireless handheld piece that weighs about 10 ounces. The unit captures five recordings to generate a spectral reading, which an algorithm in the software unit analyzes. The study found a sensitivity of 95.5% and specificity of 32.5% for melanoma detection with the device.

The target market for DermaSensor is primary care physicians, and, according to the FDA announcement in January, it is indicated for evaluating skin lesions “suggestive” of melanoma, basal cell carcinoma (BCC), and/or squamous cell carcinoma (SCC) in patients aged 40 and older to “assist healthcare providers in determining whether to refer a patient to a dermatologist.”
 

So Many Cases, So Few Dermatologists

In dermatology, AI devices have the potential to streamline the crushing burden of diagnosing skin cancer, said Yun Liu, PhD, a senior staff scientist at Google Research, Mountain View, California, who’s worked on developing machine-learning tools in dermatology among other medical fields. “Many people cannot access dermatology expertise when they most need it, ie, without waiting a long time. This causes substantial morbidity for patients,” Dr. Liu said in an interview.

His own research of an AI-based tool to help primary care physicians and nurse practitioners in teledermatology practices diagnose skin conditions documented the shortage of dermatologists to triage lesions, including a finding that only about one quarter of skin conditions are seen by a specialist and that nonspecialists play a pivotal role in the management of skin lesions.

The Centers for Disease Control and Prevention reports that about 6.1 million adults are treated for BCC and SCCs each year. The American Medical Association estimates that 13,200 active dermatologists practice in the United States.
 

Overcoming Barriers to AI in Dermatology

Before AI makes significant inroads in dermatology, clinicians need to see more verifiable data, said Roxana Daneshjou, MD, PhD, assistant professor of biomedical data science and dermatology at Stanford University, Stanford, California. “One of the challenges is having the availability of models that actually improve clinical care because we have some very early prospective trials on different devices, but we don’t have large-scale randomized clinical trials of AI devices showing definitive behaviors such as improved patient outcomes, that it helps curb skin cancer, or it catches it like dermatologists but helps reduce the biopsy load,” she said. “You need good data.”

Another challenge she noted was overcoming biases built into medicine. “A lot of the image-based models are built on datasets depicting skin disease on White skin, and those models don’t work so well on people with brown and black skin, who have historically had worse outcomes and also have been underrepresented in dermatology,” said Dr. Daneshjou, an associate editor of NEJM AI.

There’s also the challenge of getting verified AI models into the clinic. “Similar to many medical AI endeavors, developing a proof-of-concept or research prototype is far easier and faster than bringing the development to real users,” Dr. Liu said. “In particular, it is important to conduct thorough validation studies on various patient populations and settings and understand how these AI tools can best fit into the workflow or patient journey.”

A study published in 2023 documented progress Google made in deploying AI models in retina specialty clinics in India and Thailand, Dr. Liu noted.

Another challenge is to avoid overdiagnosis with these new technologies, Dr. Hartman said. Her group’s study showed the DermaSensor had a positive predictive value of 16% and a negative predictive value of 98.5%. “I think there’s some question about how this will factor into overdiagnosis. Could this actually bombard dermatologists more if the positive predictive value’s only 16%?”

One key to dermatologists accepting AI tools is having a transparent process for validating them, Dr. Lee said. “Even with FDA clearance, we don’t have the transparency we need as clinicians, researchers, and advocates of machine learning and AI in healthcare.”

But, Dr. Lee noted, the FDA in June took a step toward illuminating its validation process when it adopted guiding principles for transparency for machine learning–enabled devices. “Once we can get more access to this information and have more transparency, that’s where we can think about actually about making the decision to implement or not implement into local healthcare settings,” she said. The process was further enabled by a White House executive order in October 2023 on the safe, secure, and trustworthy development and use of AI.

The experience with telehealth during the COVID-19 pandemic, when patients and providers quickly embraced the technology to stay connected, serves as a potential template for AI, Dr. Lee noted. “As we’d seen with telehealth through the pandemic, you also need the cultural evolution and the development of the infrastructure around it to actually make sure this is a sustainable implementation and a scalable implementation in healthcare.”

Dr. Lee had no relevant relationships to disclose. Dr. Hartman received funding from DermaSensor for a study. Dr. Witkowski is a cofounder of Sklip. Dr. Liu is an employee of Google Research. Dr. Daneshjou reported financial relationships with MD Algorithms, Revea, and L’Oreal.

Another challenge she noted was overcoming biases built into medicine. “A lot of the image-based models are built on datasets depicting skin disease on White skin, and those models don’t work so well on people with brown and black skin, who have historically had worse outcomes and also have been underrepresented in dermatology,” said Dr. Daneshjou, an associate editor of NEJM AI.

There’s also the challenge of getting verified AI models into the clinic. “Similar to many medical AI endeavors, developing a proof-of-concept or research prototype is far easier and faster than bringing the development to real users,” Dr. Liu said. “In particular, it is important to conduct thorough validation studies on various patient populations and settings and understand how these AI tools can best fit into the workflow or patient journey.”

A study published in 2023 documented progress Google made in deploying AI models in retina specialty clinics in India and Thailand, Dr. Liu noted.

Another challenge is to avoid overdiagnosis with these new technologies, Dr. Hartman said. Her group’s study showed the DermaSensor had a positive predictive value of 16% and a negative predictive value of 98.5%. “I think there’s some question about how this will factor into overdiagnosis. Could this actually bombard dermatologists more if the positive predictive value’s only 16%?”

One key to dermatologists accepting AI tools is having a transparent process for validating them, Dr. Lee said. “Even with FDA clearance, we don’t have the transparency we need as clinicians, researchers, and advocates of machine learning and AI in healthcare.”

But, Dr. Lee noted, the FDA in June took a step toward illuminating its validation process when it adopted guiding principles for transparency for machine learning–enabled devices. “Once we can get more access to this information and have more transparency, that’s where we can think about actually about making the decision to implement or not implement into local healthcare settings,” she said. The process was further enabled by a White House executive order in October 2023 on the safe, secure, and trustworthy development and use of AI.

The experience with telehealth during the COVID-19 pandemic, when patients and providers quickly embraced the technology to stay connected, serves as a potential template for AI, Dr. Lee noted. “As we’d seen with telehealth through the pandemic, you also need the cultural evolution and the development of the infrastructure around it to actually make sure this is a sustainable implementation and a scalable implementation in healthcare.”

Dr. Lee had no relevant relationships to disclose. Dr. Hartman received funding from DermaSensor for a study. Dr. Witkowski is a cofounder of Sklip. Dr. Liu is an employee of Google Research. Dr. Daneshjou reported financial relationships with MD Algorithms, Revea, and L’Oreal.

Emerging diagnostic technology that uses artificial intelligence (AI) has demonstrated the potential to free dermatologists from the burden of triaging skin lesions, but dermatology lags behind some other specialties in harnessing the power of AI, and confusion surrounds dermatologists’ role in using this technology, according to researchers and dermatologists investigating AI.

While some AI-integrated devices designed to triage skin lesions have emerged, including one that received Food and Drug Administration (FDA) clearance earlier in 2024, it may be some time before AI has a meaningful clinical impact in dermatology and, more specifically, the diagnosis of skin cancer, Ivy Lee, MD, a dermatologist in Pasadena, California, and chair of the American Academy of Dermatology’s augmented intelligence committee, told this news organization.

“It hasn’t really translated into clinical practice yet,” Dr. Lee said of AI in dermatology. “There have been significant advances in terms of the technical possibility and feasibility of these tools, but the translation and integration of AI into actual clinical work flows to benefit patients beyond academic research studies has been limited.” More studies and more “easily accessible and digestible information” are needed to evaluate AI tools in dermatologic practice.

“In dermatology, we’re on a cusp with AI,” said Rebecca Hartman, MD, MPH, chief of dermatology at the VA Boston Healthcare System and director of melanoma epidemiology at Brigham and Women’s Hospital, Boston, Massachusetts. “I think it’s going to come and change what we do,” which is especially true for any image-based specialty,” including radiology and pathology, in addition to dermatology.

Dr. Hartman led a study of one of these emerging technologies, the handheld elastic scattering spectroscopy device DermaSensor, which was cleared by the FDA in January for evaluating skin lesions suggestive of skin cancer.
 

Early AI Devices for Skin Cancer Detection

At the American Society for Laser Medicine and Surgery (ASLMS) meeting in April, a panel explored a number of algorithms with dermatologic applications that use AI to triage skin lesions, including DermaSensor.

Raman spectroscopy, which contains a handheld Raman probe, a diode laser, and a detecting spectrograph. A laser beam — which at 1.56 W/cm² is below the maximum permissible exposure — focuses on the skin target with a 3.5-mm spot, gathers data on the target, and feeds it back into the unit that houses the algorithm that evaluates the spot analysis. It’s still in the investigative phase. A clinical trial, published almost 5 years ago, demonstrated a sensitivity of 90%-99% and a specificity of 24%-66% for skin cancer.

A dermatoscope called Sklip clips onto a smartphone and performs what company cofounder Alexander Witkowski, MD, PhD, described as an “optical painless virtual biopsy” for at-home use. The device uploads the captured image to an AI platform for analysis. It received FDA breakthrough device designation in 2022. At the ASLMS meeting, Dr. Witkowski said that clinical performance showed the device had a 97% sensitivity and 30% specificity for skin cancer.

DermaSensor, described in the study conducted by Dr. Hartman and others as a noninvasive, point-and-click spectrometer, is a wireless handheld piece that weighs about 10 ounces. The unit captures five recordings to generate a spectral reading, which an algorithm in the software unit analyzes. The study found a sensitivity of 95.5% and specificity of 32.5% for melanoma detection with the device.

The target market for DermaSensor is primary care physicians, and, according to the FDA announcement in January, it is indicated for evaluating skin lesions “suggestive” of melanoma, basal cell carcinoma (BCC), and/or squamous cell carcinoma (SCC) in patients aged 40 and older to “assist healthcare providers in determining whether to refer a patient to a dermatologist.”
 

So Many Cases, So Few Dermatologists

In dermatology, AI devices have the potential to streamline the crushing burden of diagnosing skin cancer, said Yun Liu, PhD, a senior staff scientist at Google Research, Mountain View, California, who’s worked on developing machine-learning tools in dermatology among other medical fields. “Many people cannot access dermatology expertise when they most need it, ie, without waiting a long time. This causes substantial morbidity for patients,” Dr. Liu said in an interview.

His own research of an AI-based tool to help primary care physicians and nurse practitioners in teledermatology practices diagnose skin conditions documented the shortage of dermatologists to triage lesions, including a finding that only about one quarter of skin conditions are seen by a specialist and that nonspecialists play a pivotal role in the management of skin lesions.

The Centers for Disease Control and Prevention reports that about 6.1 million adults are treated for BCC and SCCs each year. The American Medical Association estimates that 13,200 active dermatologists practice in the United States.

William Fox, MD, a self-described “dinosaur,” works in an independent internal medicine practice with two other physicians in Charlottesville, Virginia. He is rarely able to accept new patients, and when he does see one, they often have to wait months for the appointment. He accepts the burden of many pent-up needs, along with the huge administrative chore of coordinating their care with subspecialists.

“I will probably have to make multiple visits in a quick succession in order to make sure that I stabilize all the various issues,” Dr. Fox said. Doing so for a complicated new patient is nearly impossible because of time pressures, especially as it has become increasingly difficult for his patients to access subspecialists.

Dr. Fox traced the roots of the problem to a shortage of primary care physicians.

“Primary care is a vital part of healthcare and infrastructure in the United States, and it is being eroded unfortunately, as fewer and fewer medical students and residents choose to go into the primary care field,” Fox said. “And the reason it’s being eroded partly is because it is undervalued” and under-reimbursed, he added.

A study published 2 years ago in the Journal of General Internal Medicine proved what every primary care clinician already knows: The 24-hour day simply isn’t long enough.

Assuming an average panel of 2500 patients, the authors estimated the average time needed to provide currently recommended preventive care services and vaccines, chronic disease care, and management of acute illnesses. The answer: 26.7 hours a day.

However, using a team-based approach in which the necessary care was divided between physicians, advanced practice providers, and medical assistants, the physician component could be whittled down to 9 hours.

As chair of the Board of Regents of the American College of Physicians (ACP), Dr. Fox champions the ACP’s endorsement of physician-led team-based care, which improves patient outcomes and increases well-being among health professionals. But practices like his rarely have the necessary resources to support advanced practice clinicians or social workers. “Team-based care can be achieved in larger healthcare systems that have the resources to do it,” said Dr. Fox. “We need to find a way for smaller independent practices to also participate in team-based care.”

The solution? Major reform in the current fee-for-service payment structure, which incentivizes patient volume over patient outcomes. Dr. Fox co-authored a 2022 position statement from ACP outlining strategies such as prospective payment models that could achieve high-quality care and address social inequities. “We need to evolve our payment system from a fee-for-service system into a blended system where you have some population-based payments along with fee-for-service, or a fully capitated system,” he said.
 

Advantages of Team-Based Care

When a patient wrote on a satisfaction survey “the doctor spent more time examining the computer than examining me,” Kevin Hopkins, MD, decided he needed to change some things. Now the vice chief of Cleveland Clinic’s Primary Care Institute in Cleveland, in 2010, he developed a rudimentary team-based care model consisting of himself and two medical assistants at Cleveland Clinic.

The assistants did much of the patient intake, served as scribes while Dr. Hopkins saw his patients, and completed most of the required documentation. “I was able to see 30% more patients in a day and still take great care of them,” Dr. Hopkins said.

The concept of team-based care has evolved since then, often including some combination of advanced practice providers such as physician assistants (PAs) or nurse practitioners (NPs), nurses or medical assistants, and social workers or case managers working under the leadership of a physician. According to Dr. Hopkins, the basic strategy should be that “the physician does what only the physician is uniquely trained and qualified to do.” All other tasks, such as data entry, handling refill requests and messages from the patient portal, scheduling, or patient education, can — and should — be done by someone else.

Dr. Hopkins also serves as a senior physician advisor to the American Medical Association (AMA) and an instructor for workshops like “Saving Time: Practice Innovation Boot Camp.” His advice for clinicians who would like to streamline their workflow is to start with small steps.

“You’re not going to be able to hire all the people that you’d like to have,” he said. “I encourage physicians to look around at the people that they have and what they are currently doing as a part of their roles and responsibilities.”

The AMA Team-Based Care and Workflow website provides brief continuing medical education activities on topics such as implementing lab testing prior to office visits or advanced protocols for rooming and discharge; adopting any of these strategies can help save steps during office visits.

Dr. Hopkins said the AMA is committed to reducing the regulatory burden on clinicians. Clinical compliance officers may misinterpret regulatory requirements, putting into place overly conservative internal policies and procedures. The AMA’s “Reducing Regulatory Burden Playbook” offers advice on practices that could be stopped, such as two-factor authentication for approving or signing orders unless they are for controlled substances, or started, such as writing prescriptions for chronic daily medications for the maximum allowed length. Reducing a few clicks with each log-on to the electronic health record or reducing the number of tasks physicians must complete to log on can dramatically reduce hours spent on the computer.
 

Telehealth Changes Everything

But it might be even more efficient to keep patients out of the office.

Initially piloted in Palo Alto, California, from 2018 to 2022, the Tera Practice adopted team-based care strategies in a practice that conducts most of its work virtually. Sutter Health has since expanded the concept to three “Connected Care Clinics” in the San Francisco area, which provide 80% of their care via secure messaging, telephone, or video visit. Staff work primarily from home, and patients do not need to take off work or spend time driving to in-person visits to access care.

Matthew Sakumoto, MD, is a virtualist primary care physician at Sutter Health’s San Francisco clinic and an adjunct assistant clinical professor at the University of California, San Francisco. He leads a three-person team, which typically has included either an NP or a PA, along with a licensed vocational nurse or medical assistant.

“I go into clinic once a week, but a lot of the visits are video visits, so I don’t feel the pressure to address everything all in one visit,” Dr. Sakumoto said. “It is really freeing for both me and the patient.”

For more complex patients, for example, he prioritizes one problem at a visit because his team will follow up virtually for administrative issues like refills or specialty referrals. He can easily find time to schedule a patient for a follow-up virtual visit in the next week or 2 weeks to address additional needs. And on days he and his staff work from home, patients who message with an urgent concern can often be seen by video that same day.

Dr. Sakumoto and his team have a traditional huddle in the office the morning of their clinic day to plan for the scheduled visits, but most of their days are less structured. On non-clinic days, their morning Zoom huddle has a much different focus.

“We’re saying, ‘Okay, who are our high-risk patients? Who haven’t we seen in a while?’ ” Dr. Sakumoto said. They group patients into tiers based on factors such as age, number of complex medical needs, and frequency of emergency visits or hospitalizations. They also check in with higher-risk patients who haven’t contacted the office or been seen recently.

Dr. Sakumoto noticed in medical school doctors take excellent care of the patients who show up to the clinic. “We don’t do quite as well for those that don’t show up,” he said. The hybrid-virtual model gives him time to think in a more population-based way about engaging his entire panel of patients. The majority have capitated or value-based insurance plans, providing a dedicated monthly revenue stream that funds his virtual practice.

More clinicians may be able to hire staff and adopt some of these innovative approaches if Congress approves proposed changes to Medicare and Medicaid increasing the use of value-based payment systems. Although these changes may not provide all the funding needed to reinvigorate the field of primary care medicine, Dr. Fox said, “at least some people in positions of power and responsibility are beginning to think more seriously about these issues.”

Dr. Sakumoto reported personal fees from the following companies within the past 24 months: Clearstep Health, Carbon Health, Matter Health, CareAlign, PlushCare, Teladoc, and Nabla Health. Dr. Fox and Dr. Hopkins reported no financial conflicts of interest.

They group patients into tiers based on factors such as age, number of complex medical needs, and frequency of emergency visits or hospitalizations. They also check in with higher-risk patients who haven’t contacted the office or been seen recently.

Dr. Sakumoto noticed in medical school doctors take excellent care of the patients who show up to the clinic. “We don’t do quite as well for those that don’t show up,” he said. The hybrid-virtual model gives him time to think in a more population-based way about engaging his entire panel of patients. The majority have capitated or value-based insurance plans, providing a dedicated monthly revenue stream that funds his virtual practice.

More clinicians may be able to hire staff and adopt some of these innovative approaches if Congress approves proposed changes to Medicare and Medicaid increasing the use of value-based payment systems. Although these changes may not provide all the funding needed to reinvigorate the field of primary care medicine, Dr. Fox said, “at least some people in positions of power and responsibility are beginning to think more seriously about these issues.”

Dr. Sakumoto reported personal fees from the following companies within the past 24 months: Clearstep Health, Carbon Health, Matter Health, CareAlign, PlushCare, Teladoc, and Nabla Health. Dr. Fox and Dr. Hopkins reported no financial conflicts of interest.
