TOPLINE:

Tapering glucocorticoids (GCs) does not increase the risk for flare in modified serologically active clinically quiescent (mSACQ) patients with systemic lupus erythematosus (SLE) with a low daily exposure to GC.

METHODOLOGY:

• Previous research has indicated that SACQ SLE is associated with an increased risk for flare after low-dose GC withdrawal.
• Researchers assessed the risk for flare and damage accrual after tapering GCs in mSACQ patients with SLE.
• They used data from the Asia Pacific Lupus Collaboration (APLC) to study 1850 patients (mean age, 40 years; 91.6% women) who met the criteria for SLE, including the definition of mSACQ at least once during observation and being followed up for 2 years after the first mSACQ visit.
• mSACQ was defined as a condition with serological activity but without clinical activity managed with ≤ 7.5 mg/d of -equivalent GCs, regardless of duration.
• The primary outcome was disease flare (both severe and overall) on the basis of the SELENA-SLEDAI flare index definitions.

TAKEAWAY:

• A total of 742 patients experienced an overall flare, 271 experienced a severe flare, and 180 experienced damage accrual.
• Reducing the prednisolone-equivalent GC dosage by 1 mg/d did not increase the risk for an overall (P = .27) or severe (P = .11) flare in patients initially on prednisolone-equivalent GC dosages of 0-7.5 mg/d.
• Antimalarial use decreased the risk for overall (hazard ratio [HR], 0.78; P = .002) and severe (HR, 0.59; P < .001) flares, and immunosuppressant use decreased the risk for severe flares (HR, 0.77; P = .043) but not overall flares.
• Reducing the GC dosage by 1 mg/d reduced the risk for damage accrual by 4% in patients who started taking prednisolone at a dose > 5 but ≤ 7.5 mg/d (P = .007).

IN PRACTICE:

“Cautious tapering of GCs is a feasible option for mSACQ-SLE with low daily exposure to GCs (≤ 7.5 mg/d of prednisolone-equivalent) and can reduce GC burden,” wrote the authors.

SOURCE:

The study, led by Yasuhiro Katsumata, Division of Rheumatology, Tokyo Women’s Medical University School of Medicine, Tokyo, Japan, was published online in Annals of the Rheumatic Diseases.

LIMITATIONS:

The data were collected retrospectively. A short follow-up duration might have prevented the demonstration of clear benefits in terms of damage accrual among patients receiving < 5 mg of GCs. Moreover, the findings may have limited generalizability as the majority of patients had Asian ancestry.

DISCLOSURES:

This work was supported by grants and funding from AstraZeneca, Bristol-Myers Squibb, Eli Lily, Janssen, Merck Serono, UCB, GlaxoSmithKline, Australia, and others to APLC. Some of the authors declared receiving honoraria, consulting fees, research grants, and research support from various sources.

SAN DIEGO — New guidelines for cutaneous melanoma have been issued by the National Comprehensive Cancer Network (NCCN), creating some new standards of practice that extend a slow divergence from the last set of detailed recommendations released by the American Academy of Dermatology (AAD) in 2019.

Based on the constantly evolving science that drives guidelines, the new set of NCCN recommendations reflects the latest iteration of a consensus effort to define best practice, according to Susan M. Swetter, MD, professor of dermatology and director of the Pigmented Lesion and Melanoma Program at Stanford University in California.

Dr. Swetter chaired the committee that developed the most recent NCCN guidelines, released February 12. She also chaired the work group that developed the AAD recommendations, released in 2019. Differences between the two primarily reflect evolving evidence and expert opinion over time. 
 

Next AAD Guidelines More Than 1 Year Away

The AAD guidelines are developed infrequently and in a process that can take years. The next AAD cutaneous melanoma guidelines are not likely to be released until the end of 2025 or in 2026, Dr. Swetter said at the annual meeting of the American Academy of Dermatology on March 8. In contrast, the NCCN guidelines for cutaneous melanoma are revisited frequently. The last iteration was published only 1 year ago.

More Than 50% Consensus Generally Required

The NCCN committee that issues periodic guidelines on cutaneous melanoma is formed by a rotating group of interdisciplinary melanoma specialists. More than 30 academic institutions nationwide are generally represented, and the group includes patient advocates. Typically, no comment or recommendation is provided if the committee cannot generate at least a majority endorsement (≥ 50%) on a given topic.

Overall, the majority of guidelines, including those issued by the NCCN and the AAD, are aligned, except to the degree of the time lag that provides different sets of evidence to consider. The rationale for keeping abreast of the NCCN recommendations is that updates are more frequent, according to Dr. Swetter, who noted that these are available for free once a user has registered on the NCCN website. 

Importantly, guidelines not only identify what further steps can be taken to improve diagnostic accuracy or outcomes but what practices can be abandoned to improve the benefit-to-risk ratio. As an example, surgical margins for primary melanomas have been becoming progressively smaller on the basis of evidence that larger margins increase morbidity without improving outcomes.

Although Dr. Swetter acknowledged that “we still haven’t identified the narrowest, most efficacious margins for cutaneous melanoma,” she cited studies now suggesting that margins of 2 cm appear to be sufficient even for advanced T3 and T4 tumors. Prior to the 1970s, margins of 5 cm or greater were common.

There are still many unanswered questions about optimal margins, but the 2023 NCCN guidelines already called for surgical margins of at least 1 cm and no more than 2 cm for large invasive melanomas when clinically measured around the primary tumor. Dr. Swetter said that even smaller margins can be considered “to accommodate function and/or the anatomic location.”
 

Best Margins for MIS Undefined

So far, there are no randomized trials yet to guide surgical margins or depth for many melanoma subtypes, including melanoma in situ (MIS). These are the types of data, when they become available, that change guidelines.

The list of procedures often performed, but for which there is no specific guidance from NCCN or other organizations, is long. Numerous examples were provided during the AAD symposium on guidelines, during which Dr. Swetter spoke. The bedside diagnosis of cutaneous melanoma with noninvasive testing was one.

Describing the 2-gene molecular assay for the evaluation of a suspected melanoma, Caroline C. Kim, MD, director of the Melanoma and Pigmented Lesion Program at Tufts University in Boston, explained that this tool, which is based on the presence of the LINC00158 gene and the preferentially expressed antigen in melanoma (PRAME), has limited utility as a tool for establishing a diagnosis of melanoma. But, she said, it has reasonably good reliability for ruling out melanoma, thereby providing a basis to avoid or delay further diagnostic steps, such as biopsy.

Skin biopsy, as established in the guidelines, “is still the gold standard,” but there are numerous studies indicating that patients negative for both LINC00158 and PRAME have a low risk for melanoma, she said.

“A double negative result is not 100% effective, but it is high,” said Dr. Kim, who provided several examples whereby she employed the test to follow the patient rather than do invasive testing.

This test is gaining popularity, according to Dr. Kim, who cited several surveys suggesting growing use among clinicians, but she characterized it as an adjunctive approach that should be considered in the context of guidelines. It is an example of an approach that is not yet standard practice but can be helpful if used appropriately, she noted.

Dr. Swetter and Dr. Kim report no relevant financial relationships.

“Exercise is medicine” has become something of a mantra, with good reason. There’s no doubt that regular physical activity has a broad range of health benefits. Exercise can improve circulation, help control weight, reduce stress, and boost mood — take your pick.

Lower cancer risk is also on the list — with exercise promoted as a risk-cutting strategy in government guidelines and in recommendations from professional groups such as the American Cancer Society.

Despite confidently worded recommendations, the relationship between exercise and cancer risk is much less certain than the guidelines would suggest. The bulk of the data hangs on less rigorous, observational studies that have linked physical activity to lower risks for certain cancers, but plenty of questions remain.

What are the cancer types where exercise makes a difference? How significant is that impact? And what, exactly, defines a physical activity pattern powerful enough to move the needle on cancer risk?

Here’s an overview of the state of the evidence.

Exercise and Cancer Types: A Mixed Bag

When it comes to cancer prevention strategies, guidelines uniformly endorse less couch time and more movement. But a deeper look at the science reveals a complex and often poorly understood connection between exercise and cancer risk.

For certain cancer types, the benefits of exercise on cancer risk seem fairly well established.

The latest edition of the Physical Activity Guidelines for Americans, published in 2018, cites “strong evidence” that regular exercise might curb the risks for breast and colon cancers as well as bladder, endometrial, esophageal, kidney, and gastric cancers. These guidelines also point to “moderate”-strength evidence of a protective association with lung cancer.

The evidence of a protective effect, however, is strongest for breast and colon cancers, said Jennifer Ligibel, MD, senior physician in the Breast Oncology Center at Dana-Farber Cancer Institute, Boston, . “But,” she pointed out, “that may be because they’re some of the most common cancers, and it’s been easier to detect an association.”

Guidelines from the American Cancer Society, published in 2020, align with the 2018 recommendations. 

“We believe there’s strong evidence to suggest at least eight different types of cancer are associated with physical activity,” said Erika Rees-Punia, PhD, MPH, senior principal scientist, epidemiology and behavioral research at the American Cancer Society.

That view is not universal, however. Current recommendations from the World Cancer Research Fund and American Institute for Cancer Research, for example, are more circumspect, citing only three cancers with good evidence of a protective effect from exercise: Breast (postmenopausal), colon, and endometrial.

“We definitely can’t say exercise reduces the risk of all cancers,” said Lee Jones, PhD, head of the Exercise Oncology Program at Memorial Sloan Kettering Cancer Center in New York City. “The data suggest it’s just not that simple.”

And it’s challenging to put all the evidence together, Dr. Jones added.

The physical activity guidelines are based on published systematic reviews, meta-analyses, and pooled analyses of data from observational studies that examined the relationship between physical activity — aerobic exercise, specifically — and cancer incidence. That means the evidence comes with all the limitations observational studies entail, such as how they collect information on participants’ exercise habits — which, Dr. Jones noted, is typically done via “monster questionnaires” that gauge physical activity in broad strokes.

Pooling all those findings into a meta-analysis is tricky, Dr. Jones added, because individual studies vary in important ways — from follow-up periods to how they quantify exercise and track cancer incidence.

In a study published in February in Cancer Cell, Dr. Jones and his colleagues attempted to address some of those issues by leveraging data from the PLCO screening trial.

The PLCO was a prospective study of over 60,000 US adults that compared the effects of annual screening vs usual care on cancer mortality. At enrollment, participants completed questionnaires that included an assessment of “vigorous” exercise. Based on that, Dr. Jones and his colleagues classified 55% as “exercisers” — meaning they reported 2 or more hours of vigorous exercise per week. The remaining 45%, who were in the 0 to 1 hour per week range, were deemed non-exercisers.

Over a median of 18 years, nearly 16,000 first-time invasive cancers were diagnosed, and some interesting differences between exercisers and non-exercisers emerged. The active group had lower risks for three cancers: Head and neck, with a 26% lower risk (hazard ratio [HR], 0.74), lung (a 20% lower risk), and breast (an 11% lower risk).

What was striking, however, was the lack of connection between exercise and many cancers cited in the guidelines, including colon, gastric, bladder, endometrial, and renal cancers.

Perhaps even more surprising — exercisers had higher risks for prostate cancer (12%) and melanoma (20%). This finding, Dr. Jones said, is in line with a previous pooled analysis of data from 12 US and European prospective cohorts. In this study, the most physically active participants (90th percentile) had higher risks for melanoma and prostate cancer, compared with the least active group (10th percentile).

The melanoma findings do make sense, Dr. Jones said, given that highly active people may spend a lot of time in the sun. “My advice,” Dr. Jones said, “is, if you’re exercising outside, wear sunscreen.” The prostate cancer findings, however, are more puzzling and warrant further research, he noted.

But the bottom line is that the relationship between exercise and cancer types is mixed and far from nailed down.

How Big Is the Effect?

Even if exercise reduces the risk for only certain cancers, that’s still important, particularly when those links appear strongest for common cancer types, such as breast and colon.

But how much of a difference can exercise make?

Based on the evidence, it may only be a modest one. A 2019 systematic review by the Physical Activity Guidelines Advisory Committee provided a rough estimate: Across hundreds of epidemiological studies, people with the highest physical activity levels had a 10%-20% lower risk for the cancers cited in the 2018 exercise guidelines compared with people who were least active.

These figures, however, are probably an underestimate, said Anne McTiernan, MD, PhD, a member of the advisory committee and professor of epidemiology, at Fred Hutchinson Cancer Center, Seattle.

“This is what we usually see when a factor is not measured very well,” said Dr. McTiernan, explaining that the individual studies differed in their categories of “highest” and “lowest” physical activity, such that one study’s “highest” could be another’s mid-range.

“In other words, the effects of physical activity are likely larger” than the review found, Dr. McTiernan said.

The next logical question is whether a bigger exercise “dose” — more time or higher intensity — would have a greater impact on cancer risk. A 2019 study published in the Journal of Clinical Oncology tried to clarify that by pooling data on over 750,000 participants from nine prospective cohorts.

Overall, people meeting government recommendations for exercise — equivalent to about 2.5-5 hours of weekly moderate activity, such as a brisk walk, or about 1.25-2.5 hours of more vigorous activities, like running — had lower risks for seven of 15 cancer types studied compared with less active people.

For cancers with positive findings, being on the higher end of the recommended 2.5- to 5-hour weekly range was better. Risk reductions for breast cancer, for instance, were 6% at 2.5 hours of physical activity per week and 10% at 5 hours per week. Similar trends emerged for other cancer types, including colon (8%-14%), endometrial (10%-18%), liver cancer (18%-27%), and non-Hodgkin lymphoma in women (11%-18%).

But there may be an exercise sweet spot that maximizes the cancer risk benefit.

Among people who surpassed the recommendations — exercising for more time or more intensely — the risk reduction benefit did not necessarily improve in a linear fashion. For certain cancer types, such as colon and endometrial, the benefits of more vigorous exercise “eroded at higher levels of activity,” the authors said.

The issue here is that most studies have not dug deeply into aerobic exercise habits. Often, studies present participants with a list of activities — walking, biking, and running — and ask them to estimate how often and for what duration they do each.

Plus, “we’ve usually lumped moderate and vigorous activities together,” Dr. Rees-Punia said, which means there’s a lack of “granular data” to say whether certain intensities or frequencies of exercise are optimal and for whom.

Why Exercise May Lower Cancer Risk

Exercise habits do not, of course, exist in a vacuum. Highly active people, Dr. Ligibel said, tend to be of higher socioeconomic status, leaner, and have generally healthier lifestyles than sedentary people.

Body weight is a big confounder as well. However, Dr. Rees-Punia noted, it’s also probably a reason that exercise is linked to lower cancer risks, particularly by preventing weight gain. Still, studies have found that the association between exercise and many cancers remains significant after adjusting for body mass index.

The why remains unclear, though some studies offer clues.

“There’s been some really interesting mechanistic research, suggesting that exercise may help inhibit tumor growth or upregulate the immune system,” Dr. Ligibel said.

That includes not only lab research but small intervention studies. While these studies have largely involved people who already have cancer, some have also focused on healthy individuals.

A 2019 study from Dr. Ligibel and her colleagues, which randomly assigned 49 women newly diagnosed with breast cancer to start either an exercise program or mind-body practices ahead of surgery, found exercisers, who had been active for about a month at the time of surgery, showed signs of immune system upregulation in their tumors, while the control group did not.

Among healthy postmenopausal women, a meta-analysis of six clinical trials from Dr. McTiernan and her colleagues found that exercise plus calorie reduction can reduce levels of breast cancer-related endogenous hormones, more so than calorie-cutting alone. And a 2023 study found that high-intensity exercise boosted the ranks of certain immune cells and reduced inflammation in the colon among people at high risk for colon and endometrial cancers due to Lynch syndrome.

Defining an Exercise ‘Prescription’

Despite the gaps and uncertainties in the research, government guidelines as well as those from the American Cancer Society and other medical groups are in lockstep in their exercise recommendations: Adults should strive for 150-300 minutes of moderate-intensity aerobic exercise (like brisk walking), 75-150 minutes of vigorous activity (like running), or some combination each week.

The guidelines also encourage strength training twice a week — advice that’s based on research tying those activity levels to lower risks for heart disease, diabetes, and other chronic conditions.

But there’s no “best” exercise prescription for lowering cancer risk specifically. Most epidemiological studies have examined only aerobic activity, Dr. Rees-Punia said, and there’s very little known about whether strength conditioning or other moderate heart rate-elevating activities, such as daily household chores, may reduce the risk for cancer.

Given the lack of nuance in the literature, it’s hard to say what intensities, types, or amounts of exercise are best for each individual.

Going forward, device-based measurements of physical activity could “help us sort out the effects of different intensities of exercise and possibly types,” Dr. Rees-Punia said.

But overall, Dr. McTiernan said, the data do show that the risks for several cancers are lower at the widely recommended activity levels.

“The bottom-line advice is still to exercise at least 150 minutes per week at a moderate-intensity level or greater,” Dr. McTiernan said.

Or put another way, moving beats being sedentary. It’s probably wise for everyone to sit less, noted Dr. Rees-Punia, for overall health and based on evidence tying sedentary time to the risks for certain cancers, including colon, endometrial, and lung.

There’s a practical element to consider in all of this: What physical activities will people actually do on the regular? In the big epidemiological studies, Dr. McTiernan noted, middle-aged and older adults most often report walking, suggesting that’s the preferred, or most accessible activity, for many.

“You can only benefit from the physical activity you’ll actually do,” Dr. Rees-Punia said.

Dr. Ligibel echoed that sentiment, saying she encourages patients to think about physical activity as a process: “You need to find things you like to do and work them into your daily life, in a sustainable way.

“People often talk about exercise being medicine,” Dr. Ligibel said. “But I think you could take that too far. If we get too prescriptive about it, that could take the joy away.”

“Exercise is medicine” has become something of a mantra, with good reason. There’s no doubt that regular physical activity has a broad range of health benefits. Exercise can improve circulation, help control weight, reduce stress, and boost mood — take your pick.

Lower cancer risk is also on the list — with exercise promoted as a risk-cutting strategy in government guidelines and in recommendations from professional groups such as the American Cancer Society.

Despite confidently worded recommendations, the relationship between exercise and cancer risk is much less certain than the guidelines would suggest. The bulk of the data hangs on less rigorous, observational studies that have linked physical activity to lower risks for certain cancers, but plenty of questions remain.

What are the cancer types where exercise makes a difference? How significant is that impact? And what, exactly, defines a physical activity pattern powerful enough to move the needle on cancer risk?

Here’s an overview of the state of the evidence.

Exercise and Cancer Types: A Mixed Bag

When it comes to cancer prevention strategies, guidelines uniformly endorse less couch time and more movement. But a deeper look at the science reveals a complex and often poorly understood connection between exercise and cancer risk.

For certain cancer types, the benefits of exercise on cancer risk seem fairly well established.

The latest edition of the Physical Activity Guidelines for Americans, published in 2018, cites “strong evidence” that regular exercise might curb the risks for breast and colon cancers as well as bladder, endometrial, esophageal, kidney, and gastric cancers. These guidelines also point to “moderate”-strength evidence of a protective association with lung cancer.

The evidence of a protective effect, however, is strongest for breast and colon cancers, said Jennifer Ligibel, MD, senior physician in the Breast Oncology Center at Dana-Farber Cancer Institute, Boston, . “But,” she pointed out, “that may be because they’re some of the most common cancers, and it’s been easier to detect an association.”

Guidelines from the American Cancer Society, published in 2020, align with the 2018 recommendations. 

“We believe there’s strong evidence to suggest at least eight different types of cancer are associated with physical activity,” said Erika Rees-Punia, PhD, MPH, senior principal scientist, epidemiology and behavioral research at the American Cancer Society.

That view is not universal, however. Current recommendations from the World Cancer Research Fund and American Institute for Cancer Research, for example, are more circumspect, citing only three cancers with good evidence of a protective effect from exercise: Breast (postmenopausal), colon, and endometrial.

“We definitely can’t say exercise reduces the risk of all cancers,” said Lee Jones, PhD, head of the Exercise Oncology Program at Memorial Sloan Kettering Cancer Center in New York City. “The data suggest it’s just not that simple.”

And it’s challenging to put all the evidence together, Dr. Jones added.

The physical activity guidelines are based on published systematic reviews, meta-analyses, and pooled analyses of data from observational studies that examined the relationship between physical activity — aerobic exercise, specifically — and cancer incidence. That means the evidence comes with all the limitations observational studies entail, such as how they collect information on participants’ exercise habits — which, Dr. Jones noted, is typically done via “monster questionnaires” that gauge physical activity in broad strokes.

Pooling all those findings into a meta-analysis is tricky, Dr. Jones added, because individual studies vary in important ways — from follow-up periods to how they quantify exercise and track cancer incidence.

In a study published in February in Cancer Cell, Dr. Jones and his colleagues attempted to address some of those issues by leveraging data from the PLCO screening trial.

The PLCO was a prospective study of over 60,000 US adults that compared the effects of annual screening vs usual care on cancer mortality. At enrollment, participants completed questionnaires that included an assessment of “vigorous” exercise. Based on that, Dr. Jones and his colleagues classified 55% as “exercisers” — meaning they reported 2 or more hours of vigorous exercise per week. The remaining 45%, who were in the 0 to 1 hour per week range, were deemed non-exercisers.

Over a median of 18 years, nearly 16,000 first-time invasive cancers were diagnosed, and some interesting differences between exercisers and non-exercisers emerged. The active group had lower risks for three cancers: Head and neck, with a 26% lower risk (hazard ratio [HR], 0.74), lung (a 20% lower risk), and breast (an 11% lower risk).

What was striking, however, was the lack of connection between exercise and many cancers cited in the guidelines, including colon, gastric, bladder, endometrial, and renal cancers.

Perhaps even more surprising — exercisers had higher risks for prostate cancer (12%) and melanoma (20%). This finding, Dr. Jones said, is in line with a previous pooled analysis of data from 12 US and European prospective cohorts. In this study, the most physically active participants (90th percentile) had higher risks for melanoma and prostate cancer, compared with the least active group (10th percentile).

The melanoma findings do make sense, Dr. Jones said, given that highly active people may spend a lot of time in the sun. “My advice,” Dr. Jones said, “is, if you’re exercising outside, wear sunscreen.” The prostate cancer findings, however, are more puzzling and warrant further research, he noted.

But the bottom line is that the relationship between exercise and cancer types is mixed and far from nailed down.

How Big Is the Effect?

Even if exercise reduces the risk for only certain cancers, that’s still important, particularly when those links appear strongest for common cancer types, such as breast and colon.

But how much of a difference can exercise make?

Based on the evidence, it may only be a modest one. A 2019 systematic review by the Physical Activity Guidelines Advisory Committee provided a rough estimate: Across hundreds of epidemiological studies, people with the highest physical activity levels had a 10%-20% lower risk for the cancers cited in the 2018 exercise guidelines compared with people who were least active.

These figures, however, are probably an underestimate, said Anne McTiernan, MD, PhD, a member of the advisory committee and professor of epidemiology, at Fred Hutchinson Cancer Center, Seattle.

“This is what we usually see when a factor is not measured very well,” said Dr. McTiernan, explaining that the individual studies differed in their categories of “highest” and “lowest” physical activity, such that one study’s “highest” could be another’s mid-range.

“In other words, the effects of physical activity are likely larger” than the review found, Dr. McTiernan said.

The next logical question is whether a bigger exercise “dose” — more time or higher intensity — would have a greater impact on cancer risk. A 2019 study published in the Journal of Clinical Oncology tried to clarify that by pooling data on over 750,000 participants from nine prospective cohorts.

Overall, people meeting government recommendations for exercise — equivalent to about 2.5-5 hours of weekly moderate activity, such as a brisk walk, or about 1.25-2.5 hours of more vigorous activities, like running — had lower risks for seven of 15 cancer types studied compared with less active people.

For cancers with positive findings, being on the higher end of the recommended 2.5- to 5-hour weekly range was better. Risk reductions for breast cancer, for instance, were 6% at 2.5 hours of physical activity per week and 10% at 5 hours per week. Similar trends emerged for other cancer types, including colon (8%-14%), endometrial (10%-18%), liver cancer (18%-27%), and non-Hodgkin lymphoma in women (11%-18%).

But there may be an exercise sweet spot that maximizes the cancer risk benefit.

Among people who surpassed the recommendations — exercising for more time or more intensely — the risk reduction benefit did not necessarily improve in a linear fashion. For certain cancer types, such as colon and endometrial, the benefits of more vigorous exercise “eroded at higher levels of activity,” the authors said.

The issue here is that most studies have not dug deeply into aerobic exercise habits. Often, studies present participants with a list of activities — walking, biking, and running — and ask them to estimate how often and for what duration they do each.

Plus, “we’ve usually lumped moderate and vigorous activities together,” Dr. Rees-Punia said, which means there’s a lack of “granular data” to say whether certain intensities or frequencies of exercise are optimal and for whom.

Why Exercise May Lower Cancer Risk

Exercise habits do not, of course, exist in a vacuum. Highly active people, Dr. Ligibel said, tend to be of higher socioeconomic status, leaner, and have generally healthier lifestyles than sedentary people.

Body weight is a big confounder as well. However, Dr. Rees-Punia noted, it’s also probably a reason that exercise is linked to lower cancer risks, particularly by preventing weight gain. Still, studies have found that the association between exercise and many cancers remains significant after adjusting for body mass index.

The why remains unclear, though some studies offer clues.

“There’s been some really interesting mechanistic research, suggesting that exercise may help inhibit tumor growth or upregulate the immune system,” Dr. Ligibel said.

That includes not only lab research but small intervention studies. While these studies have largely involved people who already have cancer, some have also focused on healthy individuals.

A 2019 study from Dr. Ligibel and her colleagues, which randomly assigned 49 women newly diagnosed with breast cancer to start either an exercise program or mind-body practices ahead of surgery, found exercisers, who had been active for about a month at the time of surgery, showed signs of immune system upregulation in their tumors, while the control group did not.

Among healthy postmenopausal women, a meta-analysis of six clinical trials from Dr. McTiernan and her colleagues found that exercise plus calorie reduction can reduce levels of breast cancer-related endogenous hormones, more so than calorie-cutting alone. And a 2023 study found that high-intensity exercise boosted the ranks of certain immune cells and reduced inflammation in the colon among people at high risk for colon and endometrial cancers due to Lynch syndrome.

Despite the gaps and uncertainties in the research, government guidelines as well as those from the American Cancer Society and other medical groups are in lockstep in their exercise recommendations: Adults should strive for 150-300 minutes of moderate-intensity aerobic exercise (like brisk walking), 75-150 minutes of vigorous activity (like running), or some combination each week.

Sulfites, present in foods, drinks, pharmaceuticals, and personal care products, have been named the “Allergen of the Year” for 2024 by the American Contact Dermatitis Society (ACDS).

Sulfites are currently not found in most screening patch test series, so may be missed as a relevant contact allergen, Donald V. Belsito, MD, emeritus professor in the Department of Dermatology at Columbia University, New York City, said in his presentation on the Allergen of the Year on March 7 at the annual meeting of the American Contact Dermatitis Society in San Diego. Sulfites, he noted, are distinct from sulfates, and the groups do not cross-react with each other.

Sodium disulfite, an inorganic compound, belongs to a group of sulfiting agents, which contain the sulfite ion SO₃²⁻ and include ammonium sulfite, potassium sulfite, and sodium sulfite, Dr. Belsito said. Sulfites function as antioxidants and preservatives in a range of products including food and beverages, personal care products, and pharmaceuticals.

The type of sulfite allergy diagnosed by patch testing is type IV hypersensitivity or delayed-type hypersensitivity, where patients present with pruritic, red, scaling macules, papulovesicles, and patches, Dr. Belsito told this news organization. “It is not the type I, immediate hypersensitivity that causes hives and, in some cases, anaphylaxis,” he said. Sulfites also can cause these side effects, so correct labeling of food and beverages is important, he noted.

Some common nonoccupational sulfite sources include hair coloring and bleach products, hairspray, tanning lotions, makeup, sunscreens, and deodorants, Dr. Belsito said in his presentation. Medications including topical antifungals, topical corticosteroids, and nasal solutions can be culprits, as can water in swimming pools, he noted.

In occupational settings, sulfites may be present not only in food and drink products but also can be used in production of products, such as those used for sterilization during beer and wine fermentation, Dr. Belsito said. Other potential occupational sources of sulfite exposure include healthcare settings and textile, chemical, rubber, and pharmaceutical manufacturing.

High-sulfite food products (> 100 ppm) to be aware of include dried fruit (raisins and prunes are exceptions), bottled lemon or lime juice (but not frozen products), wine, molasses, grape juice (white, or white, pink, and red sparkling), and pickled cocktail onions, Dr. Belsito said.

“Like other contact allergens, the clinical presentation correlates with exposure,” he added. A study by the North American Contact Dermatitis Group (NACDG) found that 28.8% of patients positive for sulfite allergy on patch testing presented with facial dermatitis, which was not only related to cosmetics and medications used on the face but also from products, such as shampoo, used on the scalp that dripped onto the face. “The scalp is relatively resistant to the expression of contact allergy and may not be involved at all,” he said.

According to the NACDG study, the hands were the second most common site of dermatitis associated with sulfites (20.5%) followed by generalized distribution (13.6%). These sites are to be expected, given the sources of food and beverage, personal care products, and occupational materials, Dr. Belsito said.

“Eczematous dermatitis of the lips is also common in patients with ingested food sources of sulfites,” he said.

Systemic contact dermatitis to sulfites has been documented following oral, rectal, and parental exposure, Dr. Belsito told this news organization. “Systemic dermatitis may present as a scattered/generalized dermatitis, symmetrical drug-related intertriginous and flexural exanthema (also referred to as baboon syndrome), or erythroderma,” he said.
 

How to Spot Sulfite Allergies

The exclusion of sulfites from most patch test series means that sulfite allergy diagnoses are often missed, despite the wide range of potential exposures, Dr. Belsito said.

“Most cases of allergic contact dermatitis occur at the site of application of the allergen,” he noted. Depending on the location of the dermatitis, a detailed history of exposures that includes cosmetics and topical medications, work-related materials, and foods and beverages might suggest a sulfite allergy, he said.

Given the range of potential clinical presentations and the many and varied exposures to sulfites, Dr. Belsito’s best tip for clinicians is to routinely screen for them and evaluate the many avenues of exposure if a patch test is positive, he said.

For now, he said he does not think additional research is needed on sulfites as allergens; instead, sulfites, such as sodium metabisulfite/sodium disulfite, should be included in all clinicians’ baseline screening series, he said.

The Allergen of the Year was also recently announced in the journal Dermatitis. Authors Samuel F. Ekstein, MS, and Erin M. Warshaw, MD, from the Department of Dermatology, Park Nicollet Health Services, Minneapolis, Minnesota, noted that the ACDS hoped to raise awareness of sulfites as a “significant allergen” and called for their increased inclusion in screening patch test series.

Patients identified with sulfite allergies can find alternative products on the ACDS CAMP (Contact Allergen Management Program) website, Dr. Warshaw said in an interview.

She also highlighted some examples of sulfites as allergens in healthcare settings in particular. She described one patient who presented with dermatitis at the site of three previous hand orthopedic procedures.

“Although surgical cleansers were suspected, the patient reacted to sodium metabisulfite. Review of the operating room contactants confirmed sulfites as preservatives in an injectable anesthetic and antibiotic used for wound irrigation,” she said. Another patient who had been treated for recurrent otitis externa and seborrheic dermatitis was found to be allergic to sulfites in an otic antibiotic suspension as well as in a ketoconazole cream product, she added.

In the paper, Dr. Warshaw and Mr. Ekstein called for the addition of sulfites to the test series. Although the NACDG added sodium metabisulfite to the series in 2017, sulfites are not part of the American Contact Dermatitis Core Series, they wrote. Sodium metabisulfite, they said, was added to the European baseline standard series after review of the 2019-2020 patch test reactivity and clinical relevance data.

The ACDS meeting is held every year the day before the annual meeting of the American Academy of Dermatology.

Dr. Belsito and Dr. Warshaw had no financial conflicts to disclose.

Sulfites, he noted, are distinct from sulfates, and the groups do not cross-react with each other.

Sodium disulfite, an inorganic compound, belongs to a group of sulfiting agents, which contain the sulfite ion SO₃²⁻ and include ammonium sulfite, potassium sulfite, and sodium sulfite, Dr. Belsito said. Sulfites function as antioxidants and preservatives in a range of products including food and beverages, personal care products, and pharmaceuticals.

The type of sulfite allergy diagnosed by patch testing is type IV hypersensitivity or delayed-type hypersensitivity, where patients present with pruritic, red, scaling macules, papulovesicles, and patches, Dr. Belsito told this news organization. “It is not the type I, immediate hypersensitivity that causes hives and, in some cases, anaphylaxis,” he said. Sulfites also can cause these side effects, so correct labeling of food and beverages is important, he noted.

Some common nonoccupational sulfite sources include hair coloring and bleach products, hairspray, tanning lotions, makeup, sunscreens, and deodorants, Dr. Belsito said in his presentation. Medications including topical antifungals, topical corticosteroids, and nasal solutions can be culprits, as can water in swimming pools, he noted.

In occupational settings, sulfites may be present not only in food and drink products but also can be used in production of products, such as those used for sterilization during beer and wine fermentation, Dr. Belsito said. Other potential occupational sources of sulfite exposure include healthcare settings and textile, chemical, rubber, and pharmaceutical manufacturing.

High-sulfite food products (> 100 ppm) to be aware of include dried fruit (raisins and prunes are exceptions), bottled lemon or lime juice (but not frozen products), wine, molasses, grape juice (white, or white, pink, and red sparkling), and pickled cocktail onions, Dr. Belsito said.

“Like other contact allergens, the clinical presentation correlates with exposure,” he added. A study by the North American Contact Dermatitis Group (NACDG) found that 28.8% of patients positive for sulfite allergy on patch testing presented with facial dermatitis, which was not only related to cosmetics and medications used on the face but also from products, such as shampoo, used on the scalp that dripped onto the face. “The scalp is relatively resistant to the expression of contact allergy and may not be involved at all,” he said.

According to the NACDG study, the hands were the second most common site of dermatitis associated with sulfites (20.5%) followed by generalized distribution (13.6%). These sites are to be expected, given the sources of food and beverage, personal care products, and occupational materials, Dr. Belsito said.

“Eczematous dermatitis of the lips is also common in patients with ingested food sources of sulfites,” he said.

Systemic contact dermatitis to sulfites has been documented following oral, rectal, and parental exposure, Dr. Belsito told this news organization. “Systemic dermatitis may present as a scattered/generalized dermatitis, symmetrical drug-related intertriginous and flexural exanthema (also referred to as baboon syndrome), or erythroderma,” he said.
 

How to Spot Sulfite Allergies

The exclusion of sulfites from most patch test series means that sulfite allergy diagnoses are often missed, despite the wide range of potential exposures, Dr. Belsito said.

“Most cases of allergic contact dermatitis occur at the site of application of the allergen,” he noted. Depending on the location of the dermatitis, a detailed history of exposures that includes cosmetics and topical medications, work-related materials, and foods and beverages might suggest a sulfite allergy, he said.

Given the range of potential clinical presentations and the many and varied exposures to sulfites, Dr. Belsito’s best tip for clinicians is to routinely screen for them and evaluate the many avenues of exposure if a patch test is positive, he said.

For now, he said he does not think additional research is needed on sulfites as allergens; instead, sulfites, such as sodium metabisulfite/sodium disulfite, should be included in all clinicians’ baseline screening series, he said.

The Allergen of the Year was also recently announced in the journal Dermatitis. Authors Samuel F. Ekstein, MS, and Erin M. Warshaw, MD, from the Department of Dermatology, Park Nicollet Health Services, Minneapolis, Minnesota, noted that the ACDS hoped to raise awareness of sulfites as a “significant allergen” and called for their increased inclusion in screening patch test series.

Patients identified with sulfite allergies can find alternative products on the ACDS CAMP (Contact Allergen Management Program) website, Dr. Warshaw said in an interview.

She also highlighted some examples of sulfites as allergens in healthcare settings in particular. She described one patient who presented with dermatitis at the site of three previous hand orthopedic procedures.

“Although surgical cleansers were suspected, the patient reacted to sodium metabisulfite. Review of the operating room contactants confirmed sulfites as preservatives in an injectable anesthetic and antibiotic used for wound irrigation,” she said. Another patient who had been treated for recurrent otitis externa and seborrheic dermatitis was found to be allergic to sulfites in an otic antibiotic suspension as well as in a ketoconazole cream product, she added.

In the paper, Dr. Warshaw and Mr. Ekstein called for the addition of sulfites to the test series. Although the NACDG added sodium metabisulfite to the series in 2017, sulfites are not part of the American Contact Dermatitis Core Series, they wrote. Sodium metabisulfite, they said, was added to the European baseline standard series after review of the 2019-2020 patch test reactivity and clinical relevance data.

The ACDS meeting is held every year the day before the annual meeting of the American Academy of Dermatology.

Dr. Belsito and Dr. Warshaw had no financial conflicts to disclose.

Clinicians are navigating how to begin treating their patients with lifileucel (Amtagvi, Iovance Biotherapeutics Inc.), a new treatment for melanoma with a hefty price tag.

The US Food and Drug Administration (FDA) recently approved the tumor-infiltrating lymphocyte cell therapy (TIL) for use in certain adults with unresectable or metastatic melanoma. This marks the first time the FDA has allowed a cellular therapy to be marketed for a solid tumor cancer.

Lifileucel is made from a patient’s surgically removed tumor. Tissue from that tumor is then sent to a manufacturing center. Turnaround time to when the drug is ready to be sent back to the cancer center for use is approximately 34 days, according to the drug’s manufacturer, Iovance.
 

Insurance Adjustments

The cost of the one-time lifileucel treatment is $515,000, according to the manufacturer.

Two investigators in the clinical trials of lifileucel, Allison Betof Warner, MD, of Stanford University, Stanford, California, and Igor Puzanov, MD, of Roswell Park Comprehensive Cancer Center, Buffalo, New York, shared their expectations regarding factors that would contribute to how much a patient paid for the drug.

Given the drug’s recent approval, the logistical details are still being worked out between cancer centers and insurers regarding how much patients will pay out of pocket for lifileucel, said Dr. Betof Warner, who is assistant professor in the Department of Medicine, Division of Medical Oncology at Stanford University.

The associated costs, including the surgery that is needed to procure the TIL cells for expansion into the final drug product, will be different for each patient, she told this publication.

Patients’ costs for lifileucel will vary based on their insurance, explained Dr. Puzanov, chief of melanoma and professor of oncology at Roswell Park Comprehensive Cancer Center.

At Roswell Park, “we will work with our regionally-based payers on a case-by-case basis to seek approval for those patients we believe can most benefit from lifileucel,” he said in an interview. Preauthorization will be required, as is standard for many cancer treatments, he added.

Once payer approval is in place, Dr. Puzanov said, he did not anticipate significant delays in access for patients.

Certified centers such as the multidisciplinary team at Roswell Park are ready to treat patients now. Other centers are similarly prepared, especially those involved in the clinical trials of lifileucel, he said.

 

Logistics and Infrastructure

A position article and guidelines on the management of and best practices for TIL was published in the Journal for ImmunoTherapy of Cancer on February 29. The paper, of which both Dr. Betof Warner and Dr. Puzanov served as authors, noted that one of the barriers to the use of TIL cell therapy in clinical practice is the need for state-of-the art infrastructure at centers that want to offer the treatment. Scheduling, patient referrals, and surgery, as well as the production and infusion of TIL, must be organized and streamlined for successful treatment, the authors wrote.

The two supply chains involved in TIL — the transportation of the tumor tissue from the treatment center to the manufacturer and transport of the TIL infusion product back to the treatment center — must be timely and precise, they emphasized.
 

Docs Hope TIL Improves in Several Ways

Although the TIL technology is a breakthrough, “we hope to see even better efficacy and lower toxicity as further research looks at ways to improve on the current TIL standard,” Dr. Puzanov said.

More research and dose adjustments may impact patient costs and side effects, he noted. “I am looking to see TILs used in the front line, with or without checkpoint inhibitors.”

Research is needed to explore how to lower the chemotherapy doses and possibly the associated toxicity, he added. Finally, researchers must consider whether high-dose IL-2 therapy — given as part of the TIL cell therapy — could be replaced with other cytokines, or whether the number of doses could be lowered. Another avenue of exploration is engineering genes for cytokines into TILs, he said.

“The key is to think about TIL therapy before you need it — ideally, when the patient is still doing well on their frontline checkpoint inhibition immunotherapy,” Dr. Puzanov said in an interview. That is the time for evaluation, and specialty centers can provide an expert assessment, he said.

“We are constantly working to improve TIL therapy,” Dr. Betof Warner told this publication. More research is needed optimize the regimen to reduce side effects, which would not only make treatment easier for currently eligible patients, but might allow treatment for patients not currently eligible.

“For example, we are looking for ways to reduce the dose of preparative chemotherapy, which prepares the body for the cells to maximize their longevity and efficacy, and to reduce or eliminate the need to give IL-2 after the cell administration,” continued Dr. Betof Warner, who is also Director of Melanoma Medical Oncology, Director of Solid Tumor Cellular Therapy, and Codirector of the Pigmented Lesion and Melanoma Program at Stanford University. “We are also actively studying next-generation TIL therapies to try to increase the efficacy.”

“Lifileucel has about a 30% success rate for melanoma that has progressed after standard therapy; we are working hard to do better than that,” she noted.  

In a press release, Iovance summarized the results of the trial that supported the FDA’s accelerated approval of lifileucel. In an open-label single-arm study, including multiple sites worldwide, 73 adults with unresectable or metastatic melanoma who had received at least one previous systemic therapy underwent a lymphodepleting regimen followed by treatments with fludarabine and aldesleukin. Patients then received lifileucel at a median dose of 21.1 x 109 viable cells; the recommended dose ranges from 7.5 x 109 to 72 x 109 cells.

The primary efficacy outcome was objective response rate (ORR). The ORR in the study was 31.5%, and the median time to initial lifileucel response was 1.5 months.

The clinical trials of lifileucel for which Dr. Betof Warner and Dr. Puzanov served as investigators were sponsored by Iovance.

Hospital administrators and some department heads have been vocal about the potential for unions to affect both the attending-resident relationship and the ability for residents to directly discuss concerns and educational plans.

Critics feel that having a third party at the table, such as a union representative who isn’t as knowledgeable about the nuances of medical education, could complicate the decision-making process.

Sometimes, there are institution-specific issues as well. One example was at Loma Linda. They argued that unionization would go against their religious principles. They filed a lawsuit. That didn’t go through, and the residents won a few months later.

I know there’s always that one senior, older doctor who says, “Back in our day, we just worked, and we never complained.”

Look at the current situation that residents are facing now, with housing and rent prices and increasing costs of childcare. Sprinkle in some inflation, poor hospital staffing, increasing workload, and add in the fact that the average first-year resident salary in 2023 was around $64,000.

Now, if you look back to 2012, the average salary was around $55,000. If you adjust that for inflation, it would be around $75,000 today, which is more than what the average resident is getting paid.

Then, there are hospital administrators who say that the hospital does not have the money to meet these demands; meanwhile, hospital graduate medical education (GME) offices receive about $150,000 of Medicare funds per resident.

Obviously, there are additional costs when it comes to training and supporting residents. In general, unionizing freaks out the people handling all the cash.

There’s also the threat of a strike, which no hospital wants on their public record. A recent highly publicized event happened at New York’s Elmhurst Hospital, when 160 residents went on strike for 3 days until a deal was made.

Critics of unionizing also cite a particular study in JAMA, which included a survey of 5700 general surgery residents at 285 programs. It found that while unions helped with vacation time and housing stipends, the unions were not associated with improved burnout rates, suicidality, job satisfaction, duty hour violations, mistreatment, educational environment, or salary.

Now, granted, this isn’t the strongest study. It only sampled one group of residents, so I wouldn’t generalize these findings, but it’s still commonly cited by anti-union advocates.

Another potential downside, which is purely anecdotal because I can’t find any data to support this, is potential retaliation against residents or harm to the attending-resident relationship.

I’m an attending. I don’t really understand this one. I don’t exactly own stock in my hospital, nor am I making millions of dollars by siphoning GME money. I’m just trying to focus on educating and supporting my residents the best I can.

Obviously, there are additional costs when it comes to training and supporting residents. In general, unionizing freaks out the people handling all the cash.

There’s also the threat of a strike, which no hospital wants on their public record. A recent highly publicized event happened at New York’s Elmhurst Hospital, when 160 residents went on strike for 3 days until a deal was made.

Critics of unionizing also cite a particular study in JAMA, which included a survey of 5700 general surgery residents at 285 programs. It found that while unions helped with vacation time and housing stipends, the unions were not associated with improved burnout rates, suicidality, job satisfaction, duty hour violations, mistreatment, educational environment, or salary.

Now, granted, this isn’t the strongest study. It only sampled one group of residents, so I wouldn’t generalize these findings, but it’s still commonly cited by anti-union advocates.

Another potential downside, which is purely anecdotal because I can’t find any data to support this, is potential retaliation against residents or harm to the attending-resident relationship.

I’m an attending. I don’t really understand this one. I don’t exactly own stock in my hospital, nor am I making millions of dollars by siphoning GME money. I’m just trying to focus on educating and supporting my residents the best I can.

This transcript has been edited for clarity.

Hospital administrators and some department heads have been vocal about the potential for unions to affect both the attending-resident relationship and the ability for residents to directly discuss concerns and educational plans.

Critics feel that having a third party at the table, such as a union representative who isn’t as knowledgeable about the nuances of medical education, could complicate the decision-making process.

Sometimes, there are institution-specific issues as well. One example was at Loma Linda. They argued that unionization would go against their religious principles. They filed a lawsuit. That didn’t go through, and the residents won a few months later.

I know there’s always that one senior, older doctor who says, “Back in our day, we just worked, and we never complained.”

Look at the current situation that residents are facing now, with housing and rent prices and increasing costs of childcare. Sprinkle in some inflation, poor hospital staffing, increasing workload, and add in the fact that the average first-year resident salary in 2023 was around $64,000.

Now, if you look back to 2012, the average salary was around $55,000. If you adjust that for inflation, it would be around $75,000 today, which is more than what the average resident is getting paid.

Then, there are hospital administrators who say that the hospital does not have the money to meet these demands; meanwhile, hospital graduate medical education (GME) offices receive about $150,000 of Medicare funds per resident.

Obviously, there are additional costs when it comes to training and supporting residents. In general, unionizing freaks out the people handling all the cash.

There’s also the threat of a strike, which no hospital wants on their public record. A recent highly publicized event happened at New York’s Elmhurst Hospital, when 160 residents went on strike for 3 days until a deal was made.

TOPLINE:

The odds of having cognitive impairment may be increased among children with atopic dermatitis, primarily among those with neurodevelopmental disorders, such as attention-deficit/hyperactivity disorder (ADHD) or a learning disability.

METHODOLOGY:

It remains unknown whether subpopulations of children with atopic dermatitis face a greater risk for cognitive impairment or not.

To determine the association, researchers drew from a weighted sample of 69,732,807 children with atopic dermatitis in the 2021 US National Health Interview Survey.

Main outcomes of interest were difficulty in learning or memory (cognitive impairment symptoms) as reported by the child’s caregiver.

The researchers performed logistic regression to compare the odds of learning or memory difficulties between 60,509,794 children without atopic dermatitis and 9,223,013 children with atopic dermatitis.

TAKEAWAY:

Children with versus without atopic dermatitis were more likely to experience difficulties with learning (10.8% [95% CI, 7.8%-15.8%] vs 5.9% [95% CI, 5.1%-6.9%]; P < .001) and difficulties with memory (11.1% [95% CI, 8.0%-15.9%] vs 5.8% [95% CI, 4.9%-6.9%]; P < .001).

On multivariable logistic regression adjusted for sociodemographic factors, asthma, food allergies, and seasonal allergies or hay fever, researchers found that having atopic dermatitis was associated with increased odds of difficulties in learning (adjusted odds ratio [aOR], 1.77; 95% CI, 1.28-2.45) and memory (aOR, 1.69; 95% CI, 1.19-2.41). 

When stratified by neurodevelopmental comorbidities, having atopic dermatitis was associated with a 2- to 3-fold greater odds of memory difficulties among children with any neurodevelopmental disorder (aOR, 2.26; 95% CI, 1.43-3.57), which included ADHD (aOR, 2.90; 95% CI, 1.60-5.24) or learning disabilities (aOR, 2.04; 95% CI, 1.04-4.00).

Having atopic dermatitis was not associated with learning or memory difficulties among children without neurodevelopmental conditions. 

IN PRACTICE:

“These findings may improve the risk stratification of children with atopic dermatitis for cognitive impairment and suggest that evaluation for cognitive impairment should be prioritized among children with atopic dermatitis and comorbid ADHD or learning disability,” the authors wrote.

SOURCE:

Corresponding author Joy Wan, MD, of the department of dermatology at Johns Hopkins University School of Medicine, Baltimore, and colleagues conducted the research, which was published on March 6, 2024, in JAMA Dermatology.

LIMITATIONS:

The study’s limitations were its cross-sectional design, reliance on caregiver reports, and the fact that National Health Interview Survey data do not include information on factors such as atopic dermatitis severity, age at atopic dermatitis diagnosis, and sleep. 

DISCLOSURES:

The study was supported by a grant from the National Institutes of Health. Dr. Wan reported receiving a grant from Pfizer and personal fees from Sun Pharmaceutical Industries and Janssen Pharmaceuticals outside the submitted work. No other study authors had disclosures to report.

TOPLINE:

Women with daily exposure to spironolactone for dermatologic conditions showed no higher risk of developing breast or gynecologic cancer than that of unexposed women.

METHODOLOGY:

• Spironolactone, used off-label for several skin conditions in women, carries a warning about an increased tumor risk associated with high doses in rat models, and its antiandrogen properties have prompted hypotheses about a possible increased risk for breast or gynecologic cancers.
• The researchers reviewed data on 420 women with a history of spironolactone use for acne, hair loss, and hirsutism and 3272 women with no spironolactone use at the authors› institution. Their mean age ranged from 42 to 63 years; the majority were White, and 38% were non-White.
• Median spironolactone doses ranged from 25 mg to 225 mg; chart reviews included 5-year follow-up data from the first spironolactone exposure to allow time for tumor development.

TAKEAWAY:

• A total of 37 of the 420 women exposed to spironolactone developed any tumors, as did 546 of the 3272 with no spironolactone exposure.
• After the researchers controlled for age and race, women exposed to spironolactone were no more likely to develop a malignant tumor than a benign tumor, compared with unexposed women (odds ratio [OR], 0.48, P = .2).
• The risk for breast or uterine cancer was not significantly different in the spironolactone and non-spironolactone groups (OR, 0.95, P > .9).

IN PRACTICE:

“Women taking spironolactone for acne, hair loss, and hirsutism and who are at low risk of breast or gynecologic cancers may be counseled to have regular gynecology follow-up, but no more frequently than the general population,” but more studies are needed to evaluate risk over longer periods of time, the researchers wrote.

SOURCE:

The lead author of the study was Rachel C. Hill, BS, a student at Weill Cornell Medical College, New York City, and Shari R. Lipner, MD, PhD, of the department of dermatology at Weill Cornell Medical College, was the corresponding author. The study was published online in The Journal of the American Academy of Dermatology.

LIMITATIONS:

The findings were limited by the retrospective design, as well as the small number of spironolactone patients analyzed, the short follow-up period, the lack of information about spironolactone courses, and the inability to control for family history of malignancy.

DISCLOSURES:

The study was supported by the National Center for Advancing Translational Sciences and a grant from the Clinical and Translational Science Center at Weill Cornell Medical College awarded to Ms. Hill. None of the authors had relevant disclosures; Dr. Lipner disclosed serving as a consultant for Ortho-Dermatologics, Eli Lilly, Moberg Pharmaceuticals, and BelleTorus Corporation.

Lawmakers have added a provision to raise Medicare payments to clinicians to a $460 billion bipartisan package of federal spending bills that passed in the House on March 6 and is expected to be passed in the Senate and signed by President Biden before then end of March 8, but industry groups have criticized it as paltry.

Lawmakers often tweak Medicare policy by adding provisions to other kinds of legislation, including the spending bills Congress must pass to keep the federal government running.

Physicians’ groups and some lawmakers have long pressed Congress to change Medicare payment rules with little success, even as inflation has caused physicians’ expenses to rise. Doctors now face a 3.4% cut to Medicare reimbursements in 2024, which would be only partly mitigated by the recently announced provision.

The Medical Group Management Association (MGMA) said the proposed increase would total 1.68%. The increase, part of a bipartisan package of bills released by the House and Senate Appropriations committees on March 3, would apply to the budget for fiscal 2024, which began on October 1, 2023.

“We are deeply disappointed with Congress’ half-hearted attempt to remedy the devastating blow physician practices were dealt by the 2024 Medicare Physician Fee Schedule,” Anders Gilberg, senior vice president of MGMA, said in a statement. “Anything less than a full reversal of the 3.4% cut is appallingly inadequate.”

The American Medical Association said it was “extremely disappointed” that the boost only eased, but did not fully reverse, a deeper planned cut.

The American Academy of Family Physicians (AAFP) also expressed disappointment with the proposed increase.

“The AAFP has repeatedly told Congress that the 3.4% Medicare payment reduction that went into effect on January 1 is untenable for family physicians and threatens patients’ access to primary care,” the group said in a statement.

“While we appreciate the partial relief, family physicians continue to face an annual threat of payment cuts that are detrimental to practices and patients,” AAFP said.

Do I deserve to be here? Am I doing what I’m supposed to be doing? Is anyone going to tell me if I’m terrible?

Kerri Palamara McGrath, MD, remembered worrying over these questions as chief resident at Massachusetts General Hospital, Boston, Massachusetts, in 2009. Having graduated from New York Medical College, she felt out of step with her peers from Ivy League medical schools and considered herself lucky to be there. In order to measure up, she felt she had to work twice as hard as everybody else.

But as Dr. McGrath moved through residency and spoke with other trainees, she had a realization. Her constant fears, the nagging voice in her head saying she wasn’t good enough, these issues weren’t exclusive to her; they were pervasive.

Today, Dr. McGrath is the director of the Center for Physician Well-Being at Massachusetts General Hospital. The facility aims to address physician stress and equip doctors with the tools to navigate personal and professional issues. Dr. McGrath is also a physician coach, a growing nonclinical field, helping doctors identify their own stressors, values, and measures of success. This type of internal work, Dr. McGrath feels, can help alleviate imposter syndrome, that inner refrain saying: I’ll never be good enough.

What Is Imposter Syndrome?

While not a formal medical diagnosis, imposter syndrome has been defined as «an internal experience of intellectual phoniness.» It›s considered an inability to internalize success and a tendency to attribute gains to external factors — for example, being in the right place at the right time.

“Many people describe imposter phenomena in medicine as fearing that others are going to realize that they don’t belong somewhere or question why they’re there,” said Dr. McGrath.

It’s a “fear of being found out,” added Jessi Gold, MD, a psychiatrist who treats physicians. “In many ways, imposter syndrome shows up as a conflict between the outer self — the metaphorical mask you’re ‘putting on’ [in order] to achieve, and the inner self — how you feel like you’re not measuring up.”

Dr. McGrath said she experienced imposter syndrome before her medical career even began. She applied to 26 medical schools. Only one accepted her. “The whole time, I was like, ‘This is the only school you got into, so you’re obviously not good enough,’” she recalled. Later, having been chosen by a “coveted” institution like Mass General, “you assume that, at some point, someone will realize that the gig is up, that everybody’s better than you.”

Where Does Imposter Syndrome Come From?

Dr. McGrath felt that in medicine, high expectations are often coupled with low self-compassion. “We are so hard on ourselves, and when we set our expectations so high, we’re constantly disappointed in ourselves,” she said. External markers of success — papers published, promotions, or even social media — can further fuel this.

It can feel like “striving for excellence in a sea of excellence,” Dr. McGrath added, and this can invite comparison.

Ravi Parikh, MD, a medical oncologist and physician-scientist at the University of Pennsylvania, Philadelphia, Pennsylvania, remembered struggling with imposter syndrome early in his career. As a new doctor, he had a ton of questions, and yet those above him seemed able to make weighty decisions on their own. The comparison shook his confidence. “I remember thinking that when I became an attending, I would just magically not have to run decisions by people,” said Dr. Parikh. But even then, the “magical” self-assurance didn’t materialize.

Research found that imposter syndrome is more likely to affect women and groups that are underrepresented in medicine. But overall, the incidence is remarkably high.

A 2023 survey published in the Journal of the American College of Surgeons found that 90% of female surgeons and more than two-thirds of male ones experienced imposter syndrome. In a 2023 study on medical students in JAMA, it was nearly universal; 97% reported feelings of imposter syndrome with women 1.7 times more likely to report it than men and underrepresented groups often three times more likely.

‘I’m Clearly in the Minority Here’

The term “imposter” also suggests a lack of belonging. If medicine doesn’t “look like you,” this can create feelings of pressure, like you’re “representing a whole group with your mere existence,” said Dr. Gold, “and you have to keep proving yourself.”

Chloe Slocum, MD, MPH, an assistant professor of physical medicine and rehabilitation at Harvard Medical School, Boston, Massachusetts, remembered that feeling of conspicuous “otherness.” As a resident, Dr. Slocum began presenting at national meetings and later pursued physician leadership training. Many of her counterparts at these events were older males. “At some programs early on, I’d wonder, ‘I’m clearly in the minority here; did they really make the right decision including me in this?’”

Reactions from those around you can also have an impact. Dr. McGrath — who is 5’ 2” and describes herself as looking “very young” — noted that when she started out, neither patients nor other providers thought she was a doctor.

“I have tried everything in the book to be seen, in somebody else’s eyes, as more consistent with a doctor,” she said. “I’ve dressed down. I’ve dressed up. I’ve worn heels. I’ve worn flats. I’ve worn glasses. I’ve done all the things. When you’re constantly being told you don’t look like a doctor, you start questioning yourself.”

The Emotional Toll

If that sounds mentally exhausting, it is. Research found that imposter syndrome is often linked with burnout, depression, and anxiety.

The need to prove yourself and prevent being “found out” can push some doctors toward traditional measurements of success — promotions or published work, said Dr. Gold. But “if you’re trying to achieve in ways that you don’t value,” she warned, “you’re going to burn out.”

On the other hand, intense self-doubt can also limit advancement. After all, if you don’t think you’re good enough, you may not apply for job opportunities or leadership positions.

This mental burden can persist over years and even decades. A 2020 review of studies on imposter syndrome noted that “it would be reassuring to believe that imposter symptoms decline with age.” Unfortunately, several studies indicated that they do not.

How to Manage Imposter Syndrome

While it can be difficult to overcome imposter syndrome, there are ways to work through it and make it less pervasive or intense. Here are some tips from our experts:

• Prioritize your mental health. This can be difficult for some physicians, but don’t ignore symptoms of depression, anxiety, or burnout. Untreated mental health conditions cloud the ability to reflect on some of the existential questions that will help you navigate imposter syndrome, said Dr. Gold.
• Assess how often you need validation and why. Try to identify what you›re feeling, what needs aren›t being met, and how you can meet those needs. You can then consider where to get that validation either internally or by connecting with a colleague. Dr. McGrath encourages physicians to ask, “What does success look like for me?” and can you make success more personal and meaningful. It might sound shocking, but rather than an unattainable ideal, success should be something that feels good.
• Know the power of teamwork. As Dr. Parikh eventually realized, collaborative care is a common and beneficial part of medicine — not something that makes you a less-than physician. “There’s a lot of opportunity to crowdsource the medical decision-making process in ways that increase your own confidence as a doctor,” he said.
• Practice self-compassion. Critical voices in your head add to an already hard and stressful world. This is where self-compassion comes in. “We don’t have much control over medicine, but we have control over how medicine makes us feel,” Dr. Gold said. Imagine treating yourself how you would treat a friend.
• Consider a physician coach.  suggests that physician coaches can help lower rates of burnout and improve well-being, resilience, professional fulfillment, and self-worth. “Coaching looks into the future to help you envision what things would look like if you were feeling differently. It helps you explore what’s in your control and how you want to shape that,” said Dr. McGrath.
• Amplify the good. Apps and web-based tools can remind you to celebrate your own achievements. The “” exercise created by J. Bryan Sexton, PhD, at the Duke Center for Healthcare Safety & Quality for example, was documented in a . When healthcare workers reflected on three good things that happened each day for 2 weeks, they reported significant improvements in depression, burnout, and work-life balance.
• Do a values check. Dr. Gold often suggested that physicians with imposter syndrome ask themselves what they value, what medicine values, and how the two line up. Pausing to consider this can guide you toward useful strategies. If you value family life but feel like medicine doesn’t, for example, you might talk with a colleague who has navigated this conflict.

Dr. Gold added that reminding yourself of the range of options can be freeing. “There’s no ‘one career’ in medicine,” she said. “There are multiple ways to be happy in medicine; there are multiple ways to be happy outside of medicine. And you’re not a failure for the path you choose.”

Do I deserve to be here? Am I doing what I’m supposed to be doing? Is anyone going to tell me if I’m terrible?

Kerri Palamara McGrath, MD, remembered worrying over these questions as chief resident at Massachusetts General Hospital, Boston, Massachusetts, in 2009. Having graduated from New York Medical College, she felt out of step with her peers from Ivy League medical schools and considered herself lucky to be there. In order to measure up, she felt she had to work twice as hard as everybody else.

But as Dr. McGrath moved through residency and spoke with other trainees, she had a realization. Her constant fears, the nagging voice in her head saying she wasn’t good enough, these issues weren’t exclusive to her; they were pervasive.

Today, Dr. McGrath is the director of the Center for Physician Well-Being at Massachusetts General Hospital. The facility aims to address physician stress and equip doctors with the tools to navigate personal and professional issues. Dr. McGrath is also a physician coach, a growing nonclinical field, helping doctors identify their own stressors, values, and measures of success. This type of internal work, Dr. McGrath feels, can help alleviate imposter syndrome, that inner refrain saying: I’ll never be good enough.

What Is Imposter Syndrome?

While not a formal medical diagnosis, imposter syndrome has been defined as «an internal experience of intellectual phoniness.» It›s considered an inability to internalize success and a tendency to attribute gains to external factors — for example, being in the right place at the right time.

“Many people describe imposter phenomena in medicine as fearing that others are going to realize that they don’t belong somewhere or question why they’re there,” said Dr. McGrath.

It’s a “fear of being found out,” added Jessi Gold, MD, a psychiatrist who treats physicians. “In many ways, imposter syndrome shows up as a conflict between the outer self — the metaphorical mask you’re ‘putting on’ [in order] to achieve, and the inner self — how you feel like you’re not measuring up.”

Dr. McGrath said she experienced imposter syndrome before her medical career even began. She applied to 26 medical schools. Only one accepted her. “The whole time, I was like, ‘This is the only school you got into, so you’re obviously not good enough,’” she recalled. Later, having been chosen by a “coveted” institution like Mass General, “you assume that, at some point, someone will realize that the gig is up, that everybody’s better than you.”

Where Does Imposter Syndrome Come From?

Dr. McGrath felt that in medicine, high expectations are often coupled with low self-compassion. “We are so hard on ourselves, and when we set our expectations so high, we’re constantly disappointed in ourselves,” she said. External markers of success — papers published, promotions, or even social media — can further fuel this.

It can feel like “striving for excellence in a sea of excellence,” Dr. McGrath added, and this can invite comparison.

Ravi Parikh, MD, a medical oncologist and physician-scientist at the University of Pennsylvania, Philadelphia, Pennsylvania, remembered struggling with imposter syndrome early in his career. As a new doctor, he had a ton of questions, and yet those above him seemed able to make weighty decisions on their own. The comparison shook his confidence. “I remember thinking that when I became an attending, I would just magically not have to run decisions by people,” said Dr. Parikh. But even then, the “magical” self-assurance didn’t materialize.

Research found that imposter syndrome is more likely to affect women and groups that are underrepresented in medicine. But overall, the incidence is remarkably high.

A 2023 survey published in the Journal of the American College of Surgeons found that 90% of female surgeons and more than two-thirds of male ones experienced imposter syndrome. In a 2023 study on medical students in JAMA, it was nearly universal; 97% reported feelings of imposter syndrome with women 1.7 times more likely to report it than men and underrepresented groups often three times more likely.
