FDA Removes Harmful Chemicals From Food Packaging
Issued on February 28, 2024, “this means the major source of dietary exposure to PFAS from food packaging like fast-food wrappers, microwave popcorn bags, take-out paperboard containers, and pet food bags is being eliminated,” the FDA said in a statement.
In 2020, the FDA had secured commitments from manufacturers to stop selling products containing PFAS used in the food packaging for grease-proofing. “Today’s announcement marks the fulfillment of these voluntary commitments,” according to the agency.
PFAS, a class of thousands of chemicals also called “forever chemicals” are widely used in consumer and industrial products. People may be exposed via contaminated food packaging (although perhaps no longer in the United States) or occupationally. Studies have found that some PFAS disrupt hormones including estrogen and testosterone, whereas others may impair thyroid function.
Endocrine Society Report Sounds the Alarm About PFAS and Others
The FDA’s announcement came just 2 days after the Endocrine Society issued a new alarm about the human health dangers from environmental EDCs including PFAS in a report covering the latest science.
“Endocrine disrupting chemicals” are individual substances or mixtures that can interfere with natural hormonal function, leading to disease or even death. Many are ubiquitous in the modern environment and contribute to a wide range of human diseases.
The new report Endocrine Disrupting Chemicals: Threats to Human Health was issued jointly with the International Pollutants Elimination Network (IPEN), a global advocacy organization. It’s an update to the Endocrine Society’s 2015 report, providing new data on the endocrine-disrupting substances previously covered and adding four EDCs not discussed in that document: Pesticides, plastics, PFAS, and children’s products containing arsenic.
At a briefing held during the United Nations Environment Assembly meeting in Nairobi, Kenya, last week, the new report’s lead author Andrea C. Gore, PhD, of the University of Texas at Austin, noted, “A well-established body of scientific research indicates that endocrine-disrupting chemicals that are part of our daily lives are making us more susceptible to reproductive disorders, cancer, diabetes, obesity, heart disease, and other serious health conditions.”
Added Dr. Gore, who is also a member of the Endocrine Society’s Board of Directors, “These chemicals pose particularly serious risks to pregnant women and children. Now is the time for the UN Environment Assembly and other global policymakers to take action to address this threat to public health.”
While the science has been emerging rapidly, global and national chemical control policies haven’t kept up, the authors said. Of particular concern is that EDCs behave differently from other chemicals in many ways, including that even very low-dose exposures can pose health threats, but policies thus far haven’t dealt with that aspect.
Moreover, “the effects of low doses cannot be predicted by the effects observed at high doses. This means there may be no safe dose for exposure to EDCs,” according to the report.
Exposures can come from household products, including furniture, toys, and food packages, as well as electronics building materials and cosmetics. These chemicals are also in the outdoor environment, via pesticides, air pollution, and industrial waste.
“IPEN and the Endocrine Society call for chemical regulations based on the most modern scientific understanding of how hormones act and how EDCs can perturb these actions. We work to educate policy makers in global, regional, and national government assemblies and help ensure that regulations correlate with current scientific understanding,” they said in the report.
New Data on Four Classes of EDCs
Chapters of the report summarized the latest information about the science of EDCs and their links to endocrine disease and real-world exposure. It included a special section about “EDCs throughout the plastics life cycle” and a summary of the links between EDCs and climate change.
The report reviewed three pesticides, including the world’s most heavily applied herbicide, glycophosphate. Exposures can occur directly from the air, water, dust, and food residues. Recent data linked glycophosphate to adverse reproductive health outcomes.
Two toxic plastic chemicals, phthalates and bisphenols, are present in personal care products, among others. Emerging evidence links them with impaired neurodevelopment, leading to impaired cognitive function, learning, attention, and impulsivity.
Arsenic has long been linked to human health conditions including cancer, but more recent evidence finds it can disrupt multiple endocrine systems and lead to metabolic conditions including diabetes, reproductive dysfunction, and cardiovascular and neurocognitive conditions.
The special section about plastics noted that they are made from fossil fuels and chemicals, including many toxic substances that are known or suspected EDCs. People who live near plastic production facilities or waste dumps may be at greatest risk, but anyone can be exposed using any plastic product. Plastic waste disposal is increasingly problematic and often foisted on lower- and middle-income countries.
‘Additional Education and Awareness-Raising Among Stakeholders Remain Necessary’
Policies aimed at reducing human health risks from EDCs have included the 2022 Plastics Treaty, a resolution adopted by 175 countries at the United Nations Environmental Assembly that “may be a significant step toward global control of plastics and elimination of threats from exposures to EDCs in plastics,” the report said.
The authors added, “While significant progress has been made in recent years connecting scientific advances on EDCs with health-protective policies, additional education and awareness-raising among stakeholders remain necessary to achieve a safer and more sustainable environment that minimizes exposure to these harmful chemicals.”
The document was produced with financial contributions from the Government of Sweden, the Tides Foundation, Passport Foundation, and other donors.

What Happens to Surgery Candidates with BHDs and Cancer?
based on data from a new study of nearly 700,000 individuals.
The reason for this association remains unclear, and highlights the need to address existing behavioral health disorders (BHDs), which can be exacerbated after a patient is diagnosed with cancer, wrote Timothy M. Pawlik, MD, of The Ohio State University, Columbus, and colleagues. A cancer diagnosis can cause not only physical stress, but mental, emotional, social, and economic stress that can prompt a new BHD, cause relapse of a previous BHD, or exacerbate a current BHD, the researchers noted.
What is Known About BHDs and Cancer?
Although previous studies have shown a possible association between BHDs and increased cancer risk, as well as reduced compliance with care, the effect of BHDs on outcomes in cancer patients undergoing surgical resection has not been examined, wrote Dr. Pawlik and colleagues.
Previous research has focused on the impact of having a preexisting serious mental illness (SMI) such as schizophrenia and bipolar disorder on cancer care.
A 2023 literature review of 27 studies published in the Journal of Medical Imaging and Radiation Sciences showed that patients with preexisting severe mental illness (such as schizophrenia or bipolar disorder) had greater cancer-related mortality. In that study, the researchers also found that patients with severe mental illness were more likely to have metastatic disease at diagnosis, but less likely to receive optimal treatments, than individuals without SMIs.
Many studies also have focused on patients developing mental health problems (including BHDs) after a cancer diagnosis, but the current study is the first known to examine outcomes in those with BHDs before cancer.
Why Was It Important to Conduct This Study?
“BHDs are a diverse set of mental illnesses that affect an individual’s psychosocial wellbeing, potentially resulting in maladaptive behaviors,” Dr. Pawlik said in an interview. BHDs, which include substance abuse, eating disorders, and sleep disorders, are less common than anxiety/depression, but have an estimated prevalence of 1.3%-3.1% among adults in the United States, he said.
What Does the New Study Add?
In the new review by Dr. Pawlik and colleagues, published in the Journal of the American College of Surgeons (Katayama ES. J Am Coll Surg. 2024 Feb 29. doi: 2024. 10.1097/XCS.0000000000000954), BHDs were defined as substance abuse, eating disorders, or sleep disorders, which had not been the focus of previous studies. The researchers reviewed data from 694,836 adult patients with lung, esophageal, gastric, liver, pancreatic, or colorectal cancer between 2018-2021 using the Medicare Standard Analytic files. A total of 46,719 patients (6.7%) had at least one BHD.
Overall, patients with a BHD were significantly less likely than those without a BHD to undergo surgical resection (20.3% vs. 23.4%). Patients with a BHD also had significantly worse long-term postoperative survival than those without BHDs (median 37.1 months vs. 46.6 months) and significantly higher in-hospital costs ($17,432 vs. 16,159, P less than .001 for all).
Among patients who underwent cancer surgery, the odds of any complication were significantly higher for those with a BHD compared to those with no BHD (odds ratio 1.32), as were the odds of a prolonged length of stay (OR 1.67) and 90-day readmission (OR 1.57).
Dr. Pawlik said he was surprised by several of the findings, including that 1 in 15 Medicare beneficiaries had a BHD diagnosis, “with male sex and minority racial status, as well as higher social vulnerability, being associated with a higher prevalence of BHD.”
Also, the independent association of having a BHD with 30%-50% higher odds of a complication, prolonged length of stay, and 90-day readmission was higher than Dr. Pawlik had anticipated.
Why Do Patients With BHDs Have Fewer Surgeries and Worse Outcomes?
The reasons for this association were likely multifactorial and may reflect the greater burden of medical comorbidity and chronic illness in many patients with BHDs because of maladaptive lifestyles or poor nutrition status, Dr. Pawlik said.
“Patients with BHDs also likely face barriers to accessing care, which was noted particularly among patients with BHDs who lived in socially vulnerable areas,” he said. BHD patients also were more likely to be treated at low-volume rather than high-volume hospitals, “which undoubtedly contributed in part to worse outcomes in this cohort of patients,” he added.
What Can Oncologists Do to Help?
The take-home message for clinicians is that BHDs are linked to worse surgical outcomes and higher health care costs in cancer patients, Dr. Pawlik said in an interview.
“Enhanced accessibility to behavioral healthcare, as well as comprehensive policy reform related to mental health services are needed to improve care of patients with BHDs,” he said. “For example, implementing psychiatry compensation programs may encourage practice in vulnerable areas,” he said.
Other strategies include a following a collaborative care model involving mental health professionals working in tandem with primary care and mid-level practitioners and increasing use and establishment of telehealth systems to improve patient access to BHD services, he said.
What Are the Limitations?
The study by Dr. Pawlik and colleagues was limited by several factors, including the lack of data on younger patients and the full range of BHDs, as well as underreporting of BHDs and the high copays for mental health care, the researchers noted. However, the results suggest that concomitant BHDs are associated with worse cancer outcomes and higher in-hospital costs, and illustrate the need to screen for and target these conditions in cancer patients, the researchers concluded.
What Are the Next Steps for Research?
The current study involved Medicare beneficiaries aged 65 years or older, and more research is needed to investigate the impact of BHDs among younger cancer patients in whom the prevalence may be higher and the impact of BHDs may be different, Dr. Pawlik said in an interview. In addition, the analysis of BHDs as a composite of substance abuse, eating disorders, and sleep disorders (because the numbers were too small to break out data for each disorder, separately) prevented investigation of potential differences and unique challenges faced by distinct subpopulations of BHD patients, he said.
“Future studies should examine the individual impact of substance abuse, eating disorders, and sleep disorders on access to surgery, as well as the potential different impact that each one of these different BHDs may have on postoperative outcomes,” Dr. Pawlik suggested.
The study was supported by The Ohio State University College of Medicine Roessler Summer Research Scholarship. The researchers had no financial conflicts to disclose.

In addition, the analysis of BHDs as a composite of substance abuse, eating disorders, and sleep disorders (because the numbers were too small to break out data for each disorder, separately) prevented investigation of potential differences and unique challenges faced by distinct subpopulations of BHD patients, he said.
“Future studies should examine the individual impact of substance abuse, eating disorders, and sleep disorders on access to surgery, as well as the potential different impact that each one of these different BHDs may have on postoperative outcomes,” Dr. Pawlik suggested.
The study was supported by The Ohio State University College of Medicine Roessler Summer Research Scholarship. The researchers had no financial conflicts to disclose.

Are Food Emulsifiers Associated With Increased Cancer Risk?
Food emulsifiers are among the most widespread food additives.
Ultraprocessed foods constitute a significant part of our diet, representing approximately 30% of energy intake in France.
Large epidemiologic studies have already linked diets rich in ultraprocessed products to an increased risk for cardiovascular diseases, diabetes, obesity, and mortality. Possible explanations for this association include the presence of additives, particularly emulsifiers. These additives are intended to improve the texture and shelf life of foods.
Recent experimental studies have shown that emulsifiers alter the gut microbiota and may lead to low-grade inflammation. Dysbiosis and chronic inflammation not only increase the risk for inflammatory bowel diseases but are also implicated in the etiology of several other chronic pathologies and certain extraintestinal cancers.
The NutriNet-Santé study provided extensive information on the dietary habits of > 100,000 French participants. A new analysis was conducted, examining the possible link between the presence of emulsifiers in the diet and cancer occurrence. Data from 92,000 participants (78.8% women) were utilized. They covered an average follow-up of 6.7 years, during which 2604 cancer cases were diagnosed, including 750 breast cancers, 322 prostate cancers, and 207 colorectal cancers.
In this cohort, the risk for cancer increased with a higher presence in the diet of products containing certain emulsifiers widely used in industrial food in Europe: Carrageenans (E407), mono- and diglycerides of fatty acids (E471), pectins (E440), and sodium carbonate (E500).
Notably, the highest consumption of mono- and diglycerides of fatty acids (E471) was associated with a 15% increase in the risk for all types of cancer, a 24% increase in breast cancer risk, and a 46% increase in prostate cancer risk. The highest consumption of carrageenans (E407) was associated with a 28% increase in breast cancer risk.
In an analysis by menopausal status, the risk for breast cancer before menopause was associated with high consumption of diphosphates (E450; 45% increase), pectins (E440; 55% increase), and sodium bicarbonate (E500; 48% increase). No link was found between emulsifier consumption and colorectal cancer risk. While some associations were observed for other emulsifiers, they did not persist in sensitivity analyses.
The European Food Safety Agency recently evaluated the risks of emulsifiers, however, and found no safety issues or need to limit daily consumption of several of them, notably E471.
It is certain that cancer is multifactorial, and a single factor (here, exposure to emulsifiers) will not significantly increase the risk. However, while not essential to human health, emulsifiers are widely prevalent in the global market. Therefore, if causality is established, the increased risk could translate into a significant number of preventable cancers at the population level. Confirmation of this causal link will need to be obtained through experimental and epidemiological studies.

Democratic Lawmakers Press Pfizer on Chemotherapy Drug Shortages
In a statement about their February 21 action, the legislators, led by Rep. Jamie Raskin (D-Md.), the committee’s ranking minority member, described their work as a follow up to an earlier investigation into price hikes of generic drugs. While the committee members queried Pfizer over the three oncology medications only, they also sent letters to drugmakers Teva and Sandoz with respect to shortages in other drug classes.
A representative for Pfizer confirmed to MDedge Oncology that the company had received the representatives’ letter but said “we have no further details to provide at this time.”
What is the basis for concern?
All three generic chemotherapy drugs are mainstay treatments used across a broad array of cancers. Though shortages have been reported for several years, they became especially acute after December 2022, when an inspection by the US Food and Drug Administration (FDA) led to regulatory action against an Indian manufacturer, Intas, that produced up to half of the platinum-based therapies supplied globally. The National Comprehensive Cancer Care Network reported in October 2023 that more than 90% of its member centers were struggling to maintain adequate supplies of carboplatin, and 70% had trouble obtaining cisplatin, while the American Society of Clinical Oncology published clinical guidance on alternative treatment strategies.
What has the government done in response to the recent shortages?
The White House and the FDA announced in September that they were working with several manufacturers to help increase supplies of the platinum-based chemotherapies and of methotrexate, and taking measures that included relaxing rules on imports. Recent guidance under a pandemic-era federal law, the 2020 CARES Act, strengthened manufacturer reporting requirements related to drug shortages, and other measures have been proposed. While federal regulators have many tools with which to address drug shortages, they cannot legally oblige a manufacturer to increase production of a drug.
What can the lawmakers expect to achieve with their letter?
By pressuring Pfizer publicly, the lawmakers may be able to nudge the company to take measures to assure more consistent supplies of the three drugs. The lawmakers also said they hoped to glean from Pfizer more insight into the root causes of the shortages and potential remedies. They noted that, in a May 2023 letter by Pfizer to customers, the company had warned of depleted and limited supplies of the three drugs and said it was “working diligently” to increase output. However, the lawmakers wrote, “the root cause is not yet resolved and carboplatin, cisplatin, and methotrexate continue to experience residual delays.”
Why did the committee target Pfizer specifically?
Pfizer and its subsidiaries are among the major manufacturers of the three generic chemotherapy agents mentioned in the letter. The legislators noted that “pharmaceutical companies may not be motivated to produce generic drugs like carboplatin, cisplatin, and methotrexate, because they are not as lucrative as producing patented brand name drugs,” and that “as a principal supplier of carboplatin, cisplatin, and methotrexate, it is critical that Pfizer continues to increase production of these life-sustaining cancer medications, even amidst potential lower profitability.”
The committee members also made reference to news reports of price-gouging with these medications, as smaller hospitals or oncology centers are forced to turn to unscrupulous third-party suppliers.
What is being demanded of Pfizer?
Pfizer was given until March 6 to respond, in writing and in a briefing with committee staff, to a six questions. These queries concern what specific steps the company has taken to increase supplies of the three generic oncology drugs, what Pfizer is doing to help avert price-gouging, whether further oncology drug shortages are anticipated, and how the company is working with the FDA on the matter.

Unleashing Our Immune Response to Quash Cancer
This article was originally published on February 10 in Eric Topol’s substack “Ground Truths.”
It’s astounding how devious cancer cells and tumor tissue can be. This week in Science we learned how certain lung cancer cells can function like “Catch Me If You Can” — changing their driver mutation and cell identity to escape targeted therapy. This histologic transformation, as seen in an experimental model, is just one of so many cancer tricks that we are learning about.
Recently, as shown by single-cell sequencing, cancer cells can steal the mitochondria from T cells, a double whammy that turbocharges cancer cells with the hijacked fuel supply and, at the same time, dismantles the immune response.
Last week, we saw how tumor cells can release a virus-like protein that unleashes a vicious autoimmune response.
And then there’s the finding that cancer cell spread predominantly is occurring while we sleep.
As I previously reviewed, the ability for cancer cells to hijack neurons and neural circuits is now well established, no less their ability to reprogram neurons to become adrenergic and stimulate tumor progression, and interfere with the immune response. Stay tuned on that for a new Ground Truths podcast with Prof Michelle Monje, a leader in cancer neuroscience, which will post soon.
Add advancing age’s immunosenescence as yet another challenge to the long and growing list of formidable ways that cancer cells, and the tumor microenvironment, evade our immune response.
An Ever-Expanding Armamentarium
Immune Checkpoint Inhibitors
The field of immunotherapies took off with the immune checkpoint inhibitors, first approved by the FDA in 2011, that take the brakes off of T cells, with the programmed death-1 (PD-1), PD-ligand1, and anti-CTLA-4 monoclonal antibodies.
But we’re clearly learning they are not enough to prevail over cancer with common recurrences, only short term success in most patients, with some notable exceptions. Adding other immune response strategies, such as a vaccine, or antibody-drug conjugates, or engineered T cells, are showing improved chances for success.
Therapeutic Cancer Vaccines
There are many therapeutic cancer vaccines in the works, as reviewed in depth here.
Here’s a list of ongoing clinical trials of cancer vaccines. You’ll note most of these are on top of a checkpoint inhibitor and use personalized neoantigens (cancer cell surface proteins) derived from sequencing (whole-exome or whole genome, RNA-sequencing and HLA-profiling) the patient’s tumor.
An example of positive findings is with the combination of an mRNA-nanoparticle vaccine with up to 34 personalized neoantigens and pembrolizumab (Keytruda) vs pembrolizumab alone in advanced melanoma after resection, with improved outcomes at 3-year follow-up, cutting death or relapse rate in half.
Antibody-Drug Conjugates (ADC)
There is considerable excitement about antibody-drug conjugates (ADC) whereby a linker is used to attach a chemotherapy agent to the checkpoint inhibitor antibody, specifically targeting the cancer cell and facilitating entry of the chemotherapy into the cell. Akin to these are bispecific antibodies (BiTEs, binding to a tumor antigen and T cell receptor simultaneously), both of these conjugates acting as “biologic” or “guided” missiles.
A very good example of the potency of an ADC was seen in a “HER2-low” breast cancer randomized trial. The absence or very low expression or amplification of the HER2 receptor is common in breast cancer and successful treatment has been elusive. A randomized trial of an ADC (trastuzumab deruxtecan) compared to physician’s choice therapy demonstrated a marked success for progression-free survival in HER2-low patients, which was characterized as “unheard-of success” by media coverage.
This strategy is being used to target some of the most difficult cancer driver mutations such as TP53 and KRAS.
Oncolytic Viruses
Modifying viruses to infect the tumor and make it more visible to the immune system, potentiating anti-tumor responses, known as oncolytic viruses, have been proposed as a way to rev up the immune response for a long time but without positive Phase 3 clinical trials.
After decades of failure, a recent trial in refractory bladder cancer showed marked success, along with others, summarized here, now providing very encouraging results. It looks like oncolytic viruses are on a comeback path.
Engineering T Cells (Chimeric Antigen Receptor [CAR-T])
As I recently reviewed, there are over 500 ongoing clinical trials to build on the success of the first CAR-T approval for leukemia 7 years ago. I won’t go through that all again here, but to reiterate most of the success to date has been in “liquid” blood (leukemia and lymphoma) cancer tumors. This week in Nature is the discovery of a T cell cancer mutation, a gene fusion CARD11-PIK3R3, from a T cell lymphoma that can potentially be used to augment CAR-T efficacy. It has pronounced and prolonged effects in the experimental model. Instead of 1 million cells needed for treatment, even 20,000 were enough to melt the tumor. This is a noteworthy discovery since CAR-T work to date has largely not exploited such naturally occurring mutations, while instead concentrating on those seen in the patient’s set of key tumor mutations.
As currently conceived, CAR-T, and what is being referred to more broadly as adoptive cell therapies, involves removing T cells from the patient’s body and engineering their activation, then reintroducing them back to the patient. This is laborious, technically difficult, and very expensive. Recently, the idea of achieving all of this via an injection of virus that specifically infects T cells and inserts the genes needed, was advanced by two biotech companies with preclinical results, one in non-human primates.
Gearing up to meet the challenge of solid tumor CAR-T intervention, there’s more work using CRISPR genome editing of T cell receptors. A.I. is increasingly being exploited to process the data from sequencing and identify optimal neoantigens.
Instead of just CAR-T, we’re seeing the emergence of CAR-macrophage and CAR-natural killer (NK) cells strategies, and rapidly expanding potential combinations of all the strategies I’ve mentioned. No less, there’s been maturation of on-off suicide switches programmed in, to limit cytokine release and promote safety of these interventions. Overall, major side effects of immunotherapies are not only cytokine release syndromes, but also include interstitial pneumonitis and neurotoxicity.
Summary
Given the multitude of ways cancer cells and tumor tissue can evade our immune response, durably successful treatment remains a daunting challenge. But the ingenuity of so many different approaches to unleash our immune response, and their combinations, provides considerable hope that we’ll increasingly meet the challenge in the years ahead. We have clearly learned that combining different immunotherapy strategies will be essential for many patients with the most resilient solid tumors.
Of concern, as noted by a recent editorial in The Lancet, entitled “Cancer Research Equity: Innovations For The Many, Not The Few,” is that these individualized, sophisticated strategies are not scalable; they will have limited reach and benefit. The movement towards “off the shelf” CAR-T and inexpensive, orally active checkpoint inhibitors may help mitigate this issue.
Notwithstanding this important concern, we’re seeing an array of diverse and potent immunotherapy strategies that are providing highly encouraging results, engendering more excitement than we’ve seen in this space for some time. These should propel substantial improvements in outcomes for patients in the years ahead. It can’t happen soon enough.

Of concern, as noted by a recent editorial in The Lancet, entitled “Cancer Research Equity: Innovations For The Many, Not The Few,” is that these individualized, sophisticated strategies are not scalable; they will have limited reach and benefit. The movement towards “off the shelf” CAR-T and inexpensive, orally active checkpoint inhibitors may help mitigate this issue.
Notwithstanding this important concern, we’re seeing an array of diverse and potent immunotherapy strategies that are providing highly encouraging results, engendering more excitement than we’ve seen in this space for some time. These should propel substantial improvements in outcomes for patients in the years ahead. It can’t happen soon enough.

It’s astounding how devious cancer cells and tumor tissue can be. This week in Science we learned how certain lung cancer cells can function like “Catch Me If You Can” — changing their driver mutation and cell identity to escape targeted therapy. This histologic transformation, as seen in an experimental model, is just one of so many cancer tricks that we are learning about.
Recently, as shown by single-cell sequencing, cancer cells can steal the mitochondria from T cells, a double whammy that turbocharges cancer cells with the hijacked fuel supply and, at the same time, dismantles the immune response.
Last week, we saw how tumor cells can release a virus-like protein that unleashes a vicious autoimmune response.
And then there’s the finding that cancer cell spread predominantly is occurring while we sleep.
As I previously reviewed, the ability for cancer cells to hijack neurons and neural circuits is now well established, no less their ability to reprogram neurons to become adrenergic and stimulate tumor progression, and interfere with the immune response. Stay tuned on that for a new Ground Truths podcast with Prof Michelle Monje, a leader in cancer neuroscience, which will post soon.
Add advancing age’s immunosenescence as yet another challenge to the long and growing list of formidable ways that cancer cells, and the tumor microenvironment, evade our immune response.
An Ever-Expanding Armamentarium
Immune Checkpoint Inhibitors
The field of immunotherapies took off with the immune checkpoint inhibitors, first approved by the FDA in 2011, that take the brakes off of T cells, with the programmed death-1 (PD-1), PD-ligand1, and anti-CTLA-4 monoclonal antibodies.
But we’re clearly learning they are not enough to prevail over cancer with common recurrences, only short term success in most patients, with some notable exceptions. Adding other immune response strategies, such as a vaccine, or antibody-drug conjugates, or engineered T cells, are showing improved chances for success.
Therapeutic Cancer Vaccines
There are many therapeutic cancer vaccines in the works, as reviewed in depth here.
Here’s a list of ongoing clinical trials of cancer vaccines. You’ll note most of these are on top of a checkpoint inhibitor and use personalized neoantigens (cancer cell surface proteins) derived from sequencing (whole-exome or whole genome, RNA-sequencing and HLA-profiling) the patient’s tumor.
An example of positive findings is with the combination of an mRNA-nanoparticle vaccine with up to 34 personalized neoantigens and pembrolizumab (Keytruda) vs pembrolizumab alone in advanced melanoma after resection, with improved outcomes at 3-year follow-up, cutting death or relapse rate in half.
Antibody-Drug Conjugates (ADC)
There is considerable excitement about antibody-drug conjugates (ADC) whereby a linker is used to attach a chemotherapy agent to the checkpoint inhibitor antibody, specifically targeting the cancer cell and facilitating entry of the chemotherapy into the cell. Akin to these are bispecific antibodies (BiTEs, binding to a tumor antigen and T cell receptor simultaneously), both of these conjugates acting as “biologic” or “guided” missiles.
A very good example of the potency of an ADC was seen in a “HER2-low” breast cancer randomized trial. The absence or very low expression or amplification of the HER2 receptor is common in breast cancer and successful treatment has been elusive. A randomized trial of an ADC (trastuzumab deruxtecan) compared to physician’s choice therapy demonstrated a marked success for progression-free survival in HER2-low patients, which was characterized as “unheard-of success” by media coverage.
This strategy is being used to target some of the most difficult cancer driver mutations such as TP53 and KRAS.
Oncolytic Viruses
Modifying viruses to infect the tumor and make it more visible to the immune system, potentiating anti-tumor responses, known as oncolytic viruses, have been proposed as a way to rev up the immune response for a long time but without positive Phase 3 clinical trials.
After decades of failure, a recent trial in refractory bladder cancer showed marked success, along with others, summarized here, now providing very encouraging results. It looks like oncolytic viruses are on a comeback path.
Engineering T Cells (Chimeric Antigen Receptor [CAR-T])
As I recently reviewed, there are over 500 ongoing clinical trials to build on the success of the first CAR-T approval for leukemia 7 years ago. I won’t go through that all again here, but to reiterate most of the success to date has been in “liquid” blood (leukemia and lymphoma) cancer tumors. This week in Nature is the discovery of a T cell cancer mutation, a gene fusion CARD11-PIK3R3, from a T cell lymphoma that can potentially be used to augment CAR-T efficacy. It has pronounced and prolonged effects in the experimental model. Instead of 1 million cells needed for treatment, even 20,000 were enough to melt the tumor. This is a noteworthy discovery since CAR-T work to date has largely not exploited such naturally occurring mutations, while instead concentrating on those seen in the patient’s set of key tumor mutations.
As currently conceived, CAR-T, and what is being referred to more broadly as adoptive cell therapies, involves removing T cells from the patient’s body and engineering their activation, then reintroducing them back to the patient. This is laborious, technically difficult, and very expensive. Recently, the idea of achieving all of this via an injection of virus that specifically infects T cells and inserts the genes needed, was advanced by two biotech companies with preclinical results, one in non-human primates.
Gearing up to meet the challenge of solid tumor CAR-T intervention, there’s more work using CRISPR genome editing of T cell receptors. A.I. is increasingly being exploited to process the data from sequencing and identify optimal neoantigens.
Instead of just CAR-T, we’re seeing the emergence of CAR-macrophage and CAR-natural killer (NK) cells strategies, and rapidly expanding potential combinations of all the strategies I’ve mentioned. No less, there’s been maturation of on-off suicide switches programmed in, to limit cytokine release and promote safety of these interventions. Overall, major side effects of immunotherapies are not only cytokine release syndromes, but also include interstitial pneumonitis and neurotoxicity.
Summary
Given the multitude of ways cancer cells and tumor tissue can evade our immune response, durably successful treatment remains a daunting challenge. But the ingenuity of so many different approaches to unleash our immune response, and their combinations, provides considerable hope that we’ll increasingly meet the challenge in the years ahead. We have clearly learned that combining different immunotherapy strategies will be essential for many patients with the most resilient solid tumors.
Of concern, as noted by a recent editorial in The Lancet, entitled “Cancer Research Equity: Innovations For The Many, Not The Few,” is that these individualized, sophisticated strategies are not scalable; they will have limited reach and benefit. The movement towards “off the shelf” CAR-T and inexpensive, orally active checkpoint inhibitors may help mitigate this issue.
Notwithstanding this important concern, we’re seeing an array of diverse and potent immunotherapy strategies that are providing highly encouraging results, engendering more excitement than we’ve seen in this space for some time. These should propel substantial improvements in outcomes for patients in the years ahead. It can’t happen soon enough.

FDA Approves First Cellular Therapy for Metastatic Melanoma
The US Food and Drug Administration (FDA) has approved lifileucel (Amtagvi, Iovance Biotherapeutics) for the treatment of certain adults with unresectable or metastatic melanoma, marking the first approval of a cellular therapy in the solid tumor setting.
Specifically, the tumor-derived autologous T-cell immunotherapy is indicated for adult patients previously treated with a programmed cell death protein 1 (PD-1)–blocking antibody, and if BRAF V600–positive, a BRAF inhibitor with or without an MEK inhibitor.
,” Samantha R. Guild, JD, president, AIM at Melanoma Foundation, stated in a press release. “This one-time cell therapy represents a promising innovation for the melanoma community, and we are excited by its potential to transform care for patients who are in dire need of additional therapeutic options.”
The approval was based on findings from the open-label single-arm global C-144-01 clinical trial, which showed an objective response rate of 31.5% in 73 patients treated within the recommended dosing rage of 7.5 x 109 to 72 x 109 viable cells. Complete responses occurred in three patients (4.1%) and partial responses occurred in 20 patients (27.4%)
Median duration of response was not reached at 18.6 months of follow-up. The median time to initial response to the therapy was 1.5 months, according to an FDA press release.
“Unresectable or metastatic melanoma is an aggressive form of cancer that can be fatal,” Peter Marks, MD, PhD, director of the FDA’s Center for Biologics Evaluation and Research stated in the FDA release. “The approval of Amtagvi represents the culmination of scientific and clinical research efforts leading to a novel T cell immunotherapy for patients with limited treatment options.”
“The melanoma community is so grateful to the patients, caregivers, and clinicians who have made the clinical trials of this therapy possible and got lifileucel to approval,” Allison Betof Warner, MD, PhD, director of Melanoma Medical Oncology at Stanford Medicine, wrote on X. “We are very excited to bring this life-saving therapy to patients ASAP! Available immediately at @StanfordCancer!!!”
For the C-144-01 trial, lifileucel was administered after a lymphodepletion regimen of 60 mg/kg/d of cyclophosphamide for 2 days followed by 25 mg/m2/d of fludarabine for 5 days. Between 3 and 34 hours after infusion, patients received 600,000 IU/Kg of the interleukin 2 aldesleukin every 8-12 hours for up to six doses to support cell expansion in vivo.
The full prescribing information for lifileucel contains a boxed warning for treatment-related mortality, prolonged severe cytopenia, severe infection, cardiopulmonary, and renal impairment. The most common adverse reactions, which occurred in at least 20% of patients, were chills, pyrexia, fatigue, tachycardia, diarrhea, febrile neutropenia, edema, rash hypotension, alopecia, infection, hypoxia, and dyspnea.
“Patients receiving this product should be closely monitored before and after infusion for signs and symptoms of adverse reactions. Treatment should be withheld or discontinued in the presence of these symptoms, as indicated,” according to the FDA statement.

Despite Good Prognosis, Early Melanoma Sparks Fear of Recurrence
Localized melanoma of the skin is highly curable with surgery, especially when the malignancy is in its early stages. Yet .
These findings come from a study of 51 patients who were treated for stage 0 (melanoma in situ) to stage IIA (Breslow thickness 1.01-2.0 mm without lymph node invasion or metastasis) disease, and who were interviewed about their experiences as survivors and their fear of recurrence.
“Consistent themes and subthemes brought up by participants included anxiety associated with follow-up skin examinations, frequent biopsy procedures attributable to screening intensity, fear of the sun, changes in sun exposure behavior, and increasing thoughts about death. Many of these experiences profoundly affected participants’ lives, despite the favorable prognosis for this group,” wrote Ayisha N. Mahama, MD, MPH, from the Dell Medical School at the University of Texas at Austin, and colleagues, in an article published online in JAMA Dermatology.
Interviews and Inventory
The investigators sought to characterize the psychological well-being of localized melanoma survivors who were treated in their practice. Participants took part in a semistructured interview and the Fear of Cancer Recurrence Inventory short form, with a score of 13 or greater indicating potential cases of clinically significant fear of recurrence.
The mean patient age was 48.5 years, and there were twice as many women as men (34 and 17, respectively). In all, 17 of the patients were treated for stage 0 melanoma, and the remainder were treated for stage I-IIA disease.
The interviews and survey revealed four main “themes” among the patients: anxiety surrounding follow-up appointments and relief after a normal examination; concerns about intensity of melanoma surveillance, including anxiety or reassurance about frequent biopsies and worries regarding familial melanoma risk; lifestyle changes related to sun exposure, such as limiting time outdoors, using sunscreen, and wearing protective clothing; and thoughts about life and death.
On the Fear of Cancer Recurrence Inventory short form, 38 of the 51 participants (75%) had a score of 13 or more points, indicating clinically significant fear of cancer recurrence, and when a higher threshold of 16 or more points were was applied, 34 participants (67%) still met the definition for clinically significant fear of recurrence.
Inform, Reassure, Counsel
“Given the crucial role that dermatologists play in diagnosing melanomas, there may be an opportunity to provide reassurance and support for patients to mitigate the psychological consequences of the diagnosis, by emphasizing the excellent life expectancy at a localized stage, particularly at stage 0. In addition, a referral to a mental health practitioner could be placed for patients with higher levels of anxiety and fear of recurrence,” Dr. Mahama and her coauthors wrote.
They also noted that their findings suggest that some individuals who undergo screening for melanoma might experience “psychological harms” from receiving a melanoma diagnosis “particularly given that many or most screening-detected early-stage melanomas will not progress.”
In an interview seeking objective commentary, a surgical oncologist who was not involved in the study said that anxiety about recurrence is common among patients with melanoma, many of whom may be unfamiliar with significant recent advances such as immunotherapy in the care of patients with more advanced disease.
“Often what we will do in addition to just sharing statistics, which are historical and don’t even necessarily reflect how much better we can do for patients now if the melanoma does recur or metastasize, is recommend close surveillance by their dermatologist,” said Sonia Cohen, MD, PhD, from the Mass General Cancer Center in Boston.
“The earlier we capture a recurrence the better we can help the patients. So that’s something we’ll recommend for patients to help give them a sense of control, and that they’re doing everything they can to capture current or new skin cancers,” she said.
Dr. Cohen and colleagues also instruct patients how to look for potential signs of recurrence, such as swollen lymph nodes or suspicious lesions. Patients who express extreme anxiety may also be referred to an oncology social worker or other support services, she said.
Also asked to comment on the results, Allison Dibiaso MSW, LICSW, a social worker at Dana-Farber Cancer Institute, Boston, Massachusetts, who specializes in melanoma, said that she often sees patients who have been successfully treated for early localized malignant melanoma who experience a fear of recurrence. “These patients frequently express feelings of uncertainty and worry, with the fear of another occurrence always on their mind. Managing this fear on a day-to-day basis can be challenging,” she told this news organization.
Moreover, patients with previous treatment for melanoma often experience significant anxiety before skin exams. “Some may feel anxious and worried a few days or weeks before their appointment wondering if something will reoccur and be discovered during the examination,” she said. “While some individuals develop coping skills to manage their anxiety beforehand, many still feel anxious about the possibility of recurrence until after the exam is over and results are confirmed.”
At Dana-Farber, patients with completely resected lesions are provided with individual counseling and have access to support groups specifically designed for patients with melanoma. In addition, a caregiver group is also available for those supporting patients with melanoma, and, “if needed, we provide referrals to therapists in their local community,” Ms. Dibiaso said.
The study was supported by awards/grants to senior author Adewole S. Adamson, MD, MPP from the Robert Wood Johnson Foundation, Dermatology Foundation, National Institutes of Health, and the American Cancer Society. All authors reported having no conflicts of interest. Dr. Cohen had no relevant conflicts of interest to disclose. Ms. Dibiaso had no relevant conflicts to disclose.

Expert Hopes to Expand Ohio Model of Melanoma Case Reporting
SAN DIEGO – Soon after Brett M. Coldiron, MD, launched his Cincinnati-based dermatology and Mohs surgery practice more than 20 years ago, he reported his first three cases of thin melanomas to the Ohio Department of Health, as mandated by state law.
“I got sent reams of paperwork to fill out that I did not understand,” Dr. Coldiron, a past president of the American College of Mohs Surgery and the American Academy of Dermatology, recalled at the annual Cutaneous Malignancy Update. “Then, I got chewed out for not reporting sooner and threatened with thousands of dollars in fines if I did not promptly report the forms in the future. It was an obnoxious experience.”
About 15 years later, while testifying at the Ohio Legislature on medical reasons to restrict the use of tanning beds, a lobbyist for the tanning bed industry told him that the melanoma rates had been stable in Ohio for the previous 5 years. “It turns out they were cherry picking certain segments of data to fit their narrative,” Dr. Coldiron said. “I was stunned and it kind of deflated me. I thought about this for a long time, and thought, ‘how do we solve this issue of reporting melanoma cases without adding work to existing staff if you’re a small practice and without spending significant amounts of money? Let’s make this easier.’ ”
In addition to reducing the use of tanning beds, proper reporting of melanoma cases is important for reasons that include efforts to increase sunscreen use and to be counted in ongoing research efforts to obtain a realistic snapshot of melanoma prevalence and incidence, he said.
Quality of melanoma case reporting relies on the Centers for Disease Control and Prevention’s National Program of Cancer Registries (NPCR), and the National Cancer Institute’s Surveillance Epidemiology and End Results (SEER) Program, which collects data on the incidence, treatment, staging, and survival for 28% of the US population. All 50 states and US territories require melanoma to be reported to the NPCR, but while most hospital systems have reporting protocols and dedicated data registrars, private practices may not.
Also, many dermatopathology practices operate independently and do not have dedicated registrars and may not report cases. “Melanoma is unique in that it is often completely managed in outpatient settings and these melanomas may never be reported,” said Dr. Coldiron, current president of the Ohio Dermatological Foundation. “That’s the practice gap.” One study published in 2018 found that only 49% of dermatologists knew that melanoma was a reportable disease and only 34% routinely reported newly diagnosed cases to their state’s cancer registry. He characterized melanoma reporting as an unfunded mandate.
“Hospitals are doing the most of them, because they have a registrar,” he said. “Small practices have to assign someone to do this, and it can be difficult to train that person. It’s time consuming. The first time we did it, it took an hour,” but, he said, taking a 2-hour tutorial from the Ohio Department of Health helped.
He noted that there is a lack of awareness and clinicians think it’s the dermatopathologist’s job to report cases, “while the dermatopathologist thinks it’s the clinician’s job,” and many of the entry fields are not applicable to thinner melanomas.
There is also a “patchwork” of ways that state departments of health accept the information, not all electronically, he continued. For example, those in Arizona, Montana, West Virginia, Delaware, Vermont, and Maine accept paper copies only, “meaning you have to download a PDF, fill it out, and fax it back to them,” Dr. Coldiron said at the meeting, which was hosted by Scripps Cancer Center.
“We have them sign a HIPAA form and take the two-hour online tutorial,” he said. They download data that Ohio dermatologists have faxed to a dedicated secure HIPAA-compliant cloud-based fax line that Dr. Coldiron has set up, and the cases are then sent to the Ohio Department of Health.
Dr. Coldiron and colleagues have also partnered with the University of Cincinnati Clermont, which offers a National Cancer Registries Association–accredited certificate program — one of several nationwide. Students in this program are trained to become cancer registrars. “The university staff are gung-ho about it because they are looking for easy cases to train the students on. Also, the Ohio Department of Health staff are keen to help train the students and even help them find jobs or hire them after they complete the degree. Staff from the department of health and college faculty are fully engaged and supervising. It’s a win-win for all.”
According to Dr. Coldiron, in 2023, 8 Ohio dermatology practices were sending their reports to the fax line he set up and 7 more have signed up in recent months, making 15 practices to date. “It’s self-perpetuating at this point,” he said. “The Ohio Department of Health and the University of Cincinnati are invested in this program long-term.” The fax service costs Dr. Coldiron $42 per month — a small price to pay, he said, for being a clearinghouse for private Ohio dermatology practices looking for a practical way to report their melanoma cases. The model has increased melanoma reporting in Ohio by 2.8% in the last 2 years, “which doesn’t seem like that many, but if there are 6500 cases of melanoma, and you can increase reporting by a couple hundred cases, that’s a lot,” he said.
His goal is to expand this model to more states. “Dermatologists, surgical oncologists, and cancer center administrators should embrace this opportunity to make their practices a clearinghouse for their state,” he said. “This is an opportunity to improve state health, quality improvement projects, help providers, and gain recognition as a center of excellence. The increase in incidence of melanoma will lend great clout to public and legislative requests for prevention, treatment, and research dollars.”
In an interview, Hugh Greenway, MD, the head of Mohs and dermatologic surgery at Scripps Clinic in San Diego, also noted that cutaneous melanoma is significantly underreported in spite of individual state requirements. “As Dr. Coldiron reminds us, the main reason is that in many cases the pathology diagnosis and report come from the dermatologist’s/dermatopathologist’s office,” Dr. Greenway said. “With no hospital or large multispecialty laboratory involved, the reporting may be incomplete or not done. This is not the case with almost all other cancers where a hospital laboratory is involved.”
If widespread adoption of Dr. Coldiron’s model can occur, he added, “then we will have much better melanoma reporting data on which to both help our patients and specialty. He is to be applauded for producing a workable solution to the problem of underreporting.”
Dr. Coldiron reported having no relevant disclosures. Dr. Greenway reported that he conducts research for Castle Biosciences. He is also course director of the annual Cutaneous Malignancy Update.

FROM MELANOMA 2024
A 74-year-old White male presented with a 1-year history of depigmented patches on the hands, arms, and face, as well as white eyelashes and eyebrows
This patient showed no evidence of recurrence in the scar where the melanoma was excised, and had no enlarged lymph nodes on palpation. His complete blood count and liver function tests were normal. A positron emission tomography (PET) scan was ordered by Dr. Nasser that revealed hypermetabolic right paratracheal, right hilar, and subcarinal lymph nodes, highly suspicious for malignant lymph nodes. The patient was referred to oncology for metastatic melanoma treatment and has been doing well on ipilimumab and nivolumab.
Vitiligo is an autoimmune condition characterized by the progressive destruction of melanocytes resulting in hypopigmentation or depigmentation of the skin. Vitiligo has been associated with cutaneous melanoma. Melanoma-associated leukoderma occurs in a portion of patients with melanoma and is correlated with a favorable prognosis. Additionally, leukoderma has been described as a side effect of melanoma treatment itself. However, cases such as this one have also been reported of vitiligo-like depigmentation presenting prior to the diagnosis of metastatic melanoma.
Melanoma, like vitiligo, is considered highly immunogenic, and cytotoxic T lymphocytes (CTLs) can recognize antigens in melanoma. Furthermore, studies have shown a vitiligo-like halo around melanoma tumors, likely caused by T-cell recruitment, and this may lead to tumor destruction, but rarely total clearance. It seems that the CTL infiltrate in both diseases is similar, but regulatory T cells are decreased in vitiligo, whereas they are present in melanomas and may contribute to the immunosuppressive tumor microenvironment found at the margin of these lesions.
Leukoderma is also associated with melanoma immunotherapy which may be described as drug-induced leukoderma. Additionally, the frequency of recognition of melanoma cells by CTLs leading to hypopigmentation appears to be higher in those with metastatic disease. High immune infiltrate with CTLs and interferon-gamma (IFN-gamma) expression by type 1 T helper cells is associated with favorable prognosis. Immunotherapy with checkpoint inhibitors has shown promise in treatment augmentation for melanoma, but not all patients fully respond to therapy. Nonetheless, development of leukoderma with these treatments has been significantly associated with good therapeutic response. Depigmentation of hair and retinal epithelium has also been reported. However, drug-induced leukoderma and vitiligo seem to have clinical and biological differences, including family history of disease and serum chemokine levels. Vaccines are in production to aid in the treatment of melanoma, but researchers must first identify the appropriate antigen(s) to include.
Conversely, vitiligo-like depigmentation has been reported as a harbinger of metastatic melanoma. Patients with previous excision of primary melanoma have presented months or years later with depigmentation and, upon further evaluation, have been diagnosed with metastatic melanoma. The prevalence of depigmentation in melanoma patients is about 3%-6%, and is estimated to be 7-10 times more common in those with melanoma than in the general population. In most cases, hypopigmentation follows the diagnosis of melanoma, with an average of 4.8 years after the initial diagnosis and 1-2 years after lymph node or distant metastases. It is unclear whether hypopigmentation occurs before or after the growth of metastatic lesions, but this clinical finding in a patient with previous melanoma may serve as an important clue to conduct further investigation for metastasis.

Despite An AI Assist, Imaging Study Shows Disparities in Diagnosing Different Skin Tones
When clinicians in a large-scale study viewed a series of digital images that showed skin diseases across skin tones and were asked to make a diagnosis, the accuracy was 38% among dermatologists and 19% among primary care physicians (PCPs). But when decision support from a deep learning system (DLS) was introduced, diagnostic accuracy increased by 33% among dermatologists and 69% among PCPs, results from a multicenter study showed.
However, the researchers found that across all images, diseases in dark skin (Fitzpatrick skin types 5 and 6) were diagnosed less accurately than diseases in light skin (Fitzpatrick skin types 1-4).
“,” researchers led by Matthew Groh, PhD, of Northwestern University’s Kellogg School of Management, wrote in their study, published online in Nature Medicine.
For the study, 389 board-certified dermatologists and 450 PCPs in 39 countries were presented with 364 images to view spanning 46 skin diseases and asked to submit up to four differential diagnoses. Nearly 80% of the images were of 8 diseases: atopic dermatitis, cutaneous T-cell lymphoma (CTCL), dermatomyositis, lichen planus, Lyme disease, pityriasis rosea, pityriasis rubra pilaris, and secondary syphilis.
Dermatologists and PCPs achieved a diagnostic accuracy of 38% and 19%, respectively, but both groups of clinicians were 4 percentage points less accurate for diagnosis of images of dark skin as compared with light skin. With assistance from DLS decision support, diagnostic accuracy increased by 33% among dermatologists and 69% among primary care physicians. Among dermatologists, DLS support generally increased diagnostic accuracy evenly across skin tones. However, among PCPs, DLS support increased their diagnostic accuracy more in light skin tones than in dark ones.
In the survey component of the study, when the participants were asked, “Do you feel you received sufficient training for diagnosing skin diseases in patients with skin of color (non-white patients)?” 67% of all PCPs and 33% of all dermatologists responded no. “Furthermore, we have found differences in how often BCDs [board-certified dermatologists] and PCPs refer patients with light and dark skin for biopsy,” the authors wrote. “Specifically, for CTCL (a life-threatening disease), we found that both BCDs and PCPs report that they would refer patients for biopsy significantly more often in light skin than dark skin. Moreover, for the common skin diseases atopic dermatitis and pityriasis rosea, we found that BCDs report they would refer patients for biopsy more often in dark skin than light skin, which creates an unnecessary overburden on patients with dark skin.”
In a press release about the study, Dr. Groh emphasized that he and other scientists who investigate human-computer interaction “have to find a way to incorporate underrepresented demographics in our research. That way we will be ready to accurately implement these models in the real world and build AI systems that serve as tools that are designed to avoid the kind of systematic errors we know humans and machines are prone to. Then you can update curricula, you can change norms in different fields and hopefully everyone gets better.”
Ronald Moy, MD, a dermatologist who practices in Beverly Hills, Calif., who was asked to comment on the work, said that the study contributes insights into physician-AI interaction and highlights the need for further training on diagnosing skin diseases in people with darker skin tones. “The strengths of this study include its large sample size of dermatologists and primary care physicians, use of quality-controlled images across skin tones, and thorough evaluation of diagnostic accuracy with and without AI assistance,” said Dr. Moy, who is a past president of the American Academy of Dermatology, the American Society for Dermatologic Surgery, and the American Board of Facial Cosmetic Surgery.
“The study is limited to diagnosis and skin tone estimation based purely on a single image, which does not fully represent a clinical evaluation,” he added. However, “it does provide important benchmark data on diagnostic accuracy disparities across skin tones, but also demonstrates that while AI assistance can improve overall diagnostic accuracy, it may exacerbate disparities for non-specialists.”
Funding for the study was provided by MIT Media Lab consortium members and the Harold Horowitz Student Research Fund. One of the study authors, P. Murali Doraiswamy, MBBS, disclosed that he has received grants, advisory fees, and/or stock from several biotechnology companies outside the scope of this work and that he is a co-inventor on several patents through Duke University. The remaining authors reported having no disclosures. Dr. Moy reported having no disclosures.
When clinicians in a large-scale study viewed a series of digital images that showed skin diseases across skin tones and were asked to make a diagnosis, the accuracy was 38% among dermatologists and 19% among primary care physicians (PCPs). But when decision support from a deep learning system (DLS) was introduced, diagnostic accuracy increased by 33% among dermatologists and 69% among PCPs, results from a multicenter study showed.
However, the researchers found that across all images, diseases in dark skin (Fitzpatrick skin types 5 and 6) were diagnosed less accurately than diseases in light skin (Fitzpatrick skin types 1-4).
“,” researchers led by Matthew Groh, PhD, of Northwestern University’s Kellogg School of Management, wrote in their study, published online in Nature Medicine.
For the study, 389 board-certified dermatologists and 450 PCPs in 39 countries were presented with 364 images to view spanning 46 skin diseases and asked to submit up to four differential diagnoses. Nearly 80% of the images were of 8 diseases: atopic dermatitis, cutaneous T-cell lymphoma (CTCL), dermatomyositis, lichen planus, Lyme disease, pityriasis rosea, pityriasis rubra pilaris, and secondary syphilis.
Dermatologists and PCPs achieved a diagnostic accuracy of 38% and 19%, respectively, but both groups of clinicians were 4 percentage points less accurate for diagnosis of images of dark skin as compared with light skin. With assistance from DLS decision support, diagnostic accuracy increased by 33% among dermatologists and 69% among primary care physicians. Among dermatologists, DLS support generally increased diagnostic accuracy evenly across skin tones. However, among PCPs, DLS support increased their diagnostic accuracy more in light skin tones than in dark ones.
In the survey component of the study, when the participants were asked, “Do you feel you received sufficient training for diagnosing skin diseases in patients with skin of color (non-white patients)?” 67% of all PCPs and 33% of all dermatologists responded no. “Furthermore, we have found differences in how often BCDs [board-certified dermatologists] and PCPs refer patients with light and dark skin for biopsy,” the authors wrote. “Specifically, for CTCL (a life-threatening disease), we found that both BCDs and PCPs report that they would refer patients for biopsy significantly more often in light skin than dark skin. Moreover, for the common skin diseases atopic dermatitis and pityriasis rosea, we found that BCDs report they would refer patients for biopsy more often in dark skin than light skin, which creates an unnecessary overburden on patients with dark skin.”
In a press release about the study, Dr. Groh emphasized that he and other scientists who investigate human-computer interaction “have to find a way to incorporate underrepresented demographics in our research. That way we will be ready to accurately implement these models in the real world and build AI systems that serve as tools that are designed to avoid the kind of systematic errors we know humans and machines are prone to. Then you can update curricula, you can change norms in different fields and hopefully everyone gets better.”
