Melanoma

Shortages of carboplatin and cisplatin have become widespread among major cancer centers, according to a survey released this week from the National Comprehensive Cancer Network.

The survey, which included responses from 27 NCCN member institutions, revealed that 93% are experiencing a shortage of carboplatin and that 70% have reported a shortage of cisplatin.

“This is an unacceptable situation,” Robert W. Carlson, MD, NCCN’s chief executive offer, said in the statement released by the network.

“We are hearing from oncologists and pharmacists across the country who have to scramble to find appropriate alternatives for treating their patients with cancer right now,” Dr. Carlson said. And while the survey results show patients are still able to get lifesaving care, “it comes at a burden to our overtaxed medical facilities.”

The NCCN called on the federal government, the pharmaceutical industry, providers, and payers to take steps to “help mitigate any impacts” from this cancer drug shortage.

“We need to work together to improve the current situation and prevent it from happening again in the future,” Dr. Carlson stressed.

Carboplatin and cisplatin, which are frequently used together for systemic treatment, are highly effective therapies prescribed to treat many cancer types, including lung, breast, and prostate cancers, as well as leukemias and lymphomas. An estimated 500,000 new patients with cancer receive these agents each year.

The current survey, conducted over the last week of May, found that 100% of responding centers are able to continue to treat patients who need cisplatin without delays.

The same cannot be said for carboplatin: only 64% of centers said they are still able to continue treating all current patients receiving the platinum-based therapy. Among 19 responding centers, 20% reported that they were continuing carboplatin regimens for some but not all patients. And 16% reported treatment delays from having to obtain prior authorization for modified treatment plans, though none reported denials.

“Carboplatin has been in short supply for months but in the last 4 weeks has reached a critical stage,” according to one survey comment. “Without additional inventory many of our sites will be out of drug by early next week.”

In response to the survey question, “Is your center experiencing a shortage of carboplatin,” others made similar comments:

• “Current shipments from established manufacturers have been paused.”
• “The supply of carboplatin available is not meeting our demands.”
• “Without additional supply in early June, we will have to implement several shortage mitigation strategies.”

Survey respondents also addressed whether manufacturers or suppliers have provided any indication of when these drugs will become readily available again. For both drugs, about 60% of respondents said no. And for those who do receive updates, many noted that the “information is tentative and variable.”

Respondents indicated that other cancer agents, including methotrexate (67%) and 5FU (26%), are also in short supply at their centers.

The shortage and the uncertainty as to when it will end are forcing some centers to develop conservation and mitigation strategies.

The NCCN has broadly outlined how the federal government, the pharmaceutical industry, providers, and payers can help with prevention and mitigation. The NCCN has called on the federal government and the pharmaceutical industry to work to secure a steady supply of core anticancer drugs and has asked payers to “put patients first and provide flexible and efficient systems of providing coverage for alternative therapies replacing anti-cancer drugs that are unavailable or in shortage.”

Overall, the survey results “demonstrate the widespread impact of the chemotherapy shortage,” said Alyssa Schatz, MSW, senior director of policy and advocacy for NCCN. “We hope that by sharing this survey and calling for united action across the oncology community, we can come together to prevent future drug shortages and ensure quality, effective, equitable, and accessible cancer care for all.”

Racial disparities in melanoma stage at diagnosis were less pronounced in a large cohort of Veterans Affairs patients, compared with a large cohort of U.S. men, a new analysis shows.

“The trend of a lower racial disparity in the VA in the proportion of melanomas with local disease and in the proportion of distant metastasis at presentation was observed across age groups,” wrote Martin A. Weinstock MD, PhD, and Rachel K. Lim, of the department of dermatology at Brown University, Providence, R.I., and the Center for Dermatoepidemiology at the VA Providence Healthcare System. The study was published online in the Journal of the American Academy of Dermatology.

“Melanoma was the fourth-most common cancer [diagnosed] in male VA patients in 2010,” wrote the authors, who also pointed out that “prior surveys found that 11%-13% of U.S. active-duty personnel routinely use sunscreen despite significant occupational sun exposure. Racial disparities are important concerns in the VA and elsewhere.”

To compare the stage of melanoma at presentation among White and non-Whites patients in the VA and in the general U.S. population, the researchers identified invasive cutaneous melanoma cases from 2000 to 2019 in the VA Corporate Data Warehouse and the Surveillance, Epidemiology and End Results Program (SEER).

They restricted the analysis to men because of the small proportion of women in the at-risk veteran population and excluded cases with an age younger than 20, those with unknown histology, and melanoma in situ. The researchers performed two-tailed z-tests to evaluate the difference in proportions of melanoma stages between the veteran population and the general population.

The analysis included 44,077 cases of invasive melanoma in the VA and 217,030 in SEER. Racial disparities in melanoma staging were substantially less pronounced in the VA than in SEER.

In the VA, localized disease represented 77.9% of melanomas among Whites versus 71.0% among non-Whites. But in SEER, localized disease represented 80.7% of melanomas among Whites versus 61.5% in non-Whites – over double the VA disparity (P < .0001).

Likewise, the disparity between Whites and nonwhites observed for regional or distant metastatic disease at presentation in the VA was lower than the disparity observed in SEER. For example, in the VA, distant metastatic disease at presentation represented 6.1% of melanomas among Whites versus 8.6% among non-Whites, while in SEER it represented 4.8% of melanomas among Whites versus 11.3% in non-Whites – again, more than double the VA disparity (P < .0001).

“These differences between the VA and SEER were less marked” among those older than 65 years, the researchers wrote. “Notably, the differences between VA and SEER in racial disparities among those greater than 65 in age were still significant for localized disease and for distant metastasis.”

The findings suggest that the VA “may be more effective in reducing racial disparities in melanoma stage at diagnosis, potentially due to all patients in the VA dataset having insured access to health care, regardless of socioeconomic status,” the researchers concluded. Similarly, the decreased difference in racial disparities observed in patients older than 65 across systems “may be related to the availability of Medicare to the older general populations. The authors acknowledged several study limitations, such as the predominantly elderly and male VA population, potentially underreported utilization of non-VA dermatologic care, and variation in geographic regions covered by each database.

Travis W. Blalock, MD, director of dermatologic surgery, Mohs micrographic surgery, and cutaneous oncology at Emory University, Atlanta, who was asked to comment on the work, said in an interview he would have liked to see a more detailed breakdown of the younger patients, “for those in their 30s and 40s, to see if this trend held up.”

He would have also liked to see how the data trended over time, adding, “while this, broadly, may be good news for our veterans, attributing this finding to a reduction in access disparity or some other organizational intervention seems a little premature. Regardless, Dr. Weinstock has given us, once again, information from our veterans to probe for the betterment of all patients.”

The researchers reported having no relevant disclosures and the study had no funding. Dr. Blalock disclosed that he has served as a principal investigator for Castle Biosciences.

CHICAGO – Sunscreen recommendations are most effective when a multitude of factors are considered, Susan C. Taylor, MD, said during a presentation on personal photoprotection at the inaugural Pigmentary Disorders Exchange Symposium.

Among the first factors physicians should consider before recommending sunscreen are a patient’s Fitzpatrick skin type, risks for burning or tanning, underlying skin disorders, and medications the patient is taking, Dr. Taylor, professor of dermatology at the University of Pennsylvania, Philadelphia, said at the meeting, provided by MedscapeLIVE! If patients are on hypertensives, for example, medications can make them more photosensitive.

Consider skin type

Dr. Taylor said she was dismayed by the results of a recent study, which found that 43% of dermatologists who responded to a survey reported that they never, rarely, or only sometimes took a patient’s skin type into account when making sunscreen recommendations. The article is referenced in a 2022 expert panel consensus paper she coauthored on photoprotection “for skin of all color.” But she pointed out that considering skin type alone is inadequate.

Questions for patients in joint decision-making should include lifestyle and work choices such as whether they work inside or outside, and how much sun exposure they get in a typical day. Heat and humidity levels should also be considered as should a patient’s susceptibility to dyspigmentation. “That could be overall darkening of the skin, mottled hyperpigmentation, actinic dyspigmentation, and, of course, propensity for skin cancer,” she said.
 

Use differs by race

Dr. Taylor, who is also vice chair for diversity, equity and inclusion in the department of dermatology at the University of Pennsylvania, pointed out that sunscreen use differs considerably by race.

In study of 8,952 adults in the United States who reported that they were sun sensitive found that a subset of adults with skin of color were significantly less likely to use sunscreen when compared with non-Hispanic White adults: Non-Hispanic Black (adjusted odds ratio, 0.43); non-Hispanic Asian (aOR. 0.54); and Hispanic (aOR, 0.70) adults.

In the study, non-Hispanic Black and Hispanic adults were significantly less likely to use sunscreens with an SPF greater than 15. In addition, non-Hispanic Black, non-Hispanic Asian, and Hispanic adults were significantly more likely than non-Hispanic Whites to wear long sleeves when outside. Such differences are important to keep in mind when advising patients about sunscreens, she said.
 

Protection for lighter-colored skin

Dr. Taylor said that, for patients with lighter skin tones, “we really want to protect against ultraviolet B as well as ultraviolet A, particularly ultraviolet A2. Ultraviolet radiation is going to cause DNA damage.” Patients with Fitzpatrick skin types I, II, or III are most susceptible to the effects of UVB with sunburn inflammation, which will cause erythema and tanning, and immunosuppression.

“For those who are I, II, and III, we do want to recommend a broad-spectrum, photostable sunscreen with a critical wavelength of 370 nanometers, which is going to protect from both UVB and UVA2,” she said.

Sunscreen recommendations are meant to be paired with advice to avoid midday sun from 10 a.m. to 2 p.m., wearing protective clothing and accessories, and seeking shade, she noted.

Dr. Taylor said, for those patients with lighter skin who are more susceptible to photodamage and premature aging, physicians should recommend sunscreens that contain DNA repair enzymes such as photolyases and sunscreens that contain antioxidants that can prevent or reverse DNA damage. “The exogenous form of these lyases have been manufactured and added to sunscreens,” Dr. Taylor said. “They’re readily available in the United States. That is something to consider for patients with significant photodamage.”

Retinoids can also help alleviate or reverse photodamage, she added.
 

Protection for darker-colored skin

“Many people of color do not believe they need sunscreen,” Dr. Taylor said. But studies show that, although there may be more intrinsic protection, sunscreen is still needed.

Over 30 years ago, Halder and colleagues reported that melanin in skin of color can filter two to five times more UV radiation, and in a paper on the photoprotective role of melanin, Kaidbey and colleagues found that skin types V and VI had an intrinsic SPF of 13 when compared with those who have lighter complexions, which had an SPF of 3.

Sunburns seem to occur less frequently in people with skin of color, but that may be because erythema is less apparent in people with darker skin tones or because of differences in personal definitions of sunburn, Dr. Taylor said.

“Skin of color can and does sustain sunburns and sunscreen will help prevent that,” she said, adding that a recommendation of an SPF 30 is likely sufficient for these patients. Dr. Taylor noted that sunscreens for patients with darker skin often cost substantially more than those for lighter skin, and that should be considered in recommendations.

Tinted sunscreens

Dr. Taylor said that, while broad-spectrum photostable sunscreens protect against UVB and UVA 2, they don’t protect from visible light and UVA1. Two methods to add that protection are using inorganic tinted sunscreens that contain iron oxide or pigmentary titanium dioxide. Dr. Taylor was a coauthor of a practical guide to tinted sunscreens published in 2022.

“For iron oxide, we want a concentration of 3% or greater,” she said, adding that the percentage often is not known because if it is contained in a sunscreen, it is listed as an inactive ingredient.

Another method to address visible light and UVA1 is the use of antioxidant-containing sunscreens with vitamin E, vitamin C, or licochalcone A, Dr. Taylor said.

During the question-and-answer period following her presentation, Amit Pandya, MD, adjunct professor of dermatology at University of Texas Southwestern Medical Center, Dallas, asked why “every makeup, every sunscreen, just says iron oxide,” since it is known that visible light will cause pigmentation, especially in those with darker skin tones.

He urged pushing for a law that would require listing the percentage of iron oxide on products to assure it is sufficient, according to what the literature recommends.

Conference Chair Pearl Grimes, MD, director of the Vitiligo and Pigmentation Institute of Southern California, Los Angeles, said that she recommends tinted sunscreens almost exclusively for her patients, but those with darker skin colors struggle to match color.

Dr. Taylor referred to an analysis published in 2022 of 58 over-the counter sunscreens, which found that only 38% of tinted sunscreens was available in more than one shade, “which is a problem for many of our patients.” She said that providing samples with different hues and tactile sensations may help patients find the right product.

Dr. Taylor disclosed being on the advisory boards for AbbVie, Avita Medical, Beiersdorf, Biorez, Eli Lily, EPI Health, Evolus, Galderma, Hugel America, Johnson and Johnson, L’Oreal USA, MedScape, Pfizer, Scientis US, UCB, Vichy Laboratories. She is a consultant for Arcutis Biothermapeutics, Beiersdorf, Bristol-Myers Squibb, Cara Therapeutics, Dior, and Sanofi. She has done contracted research for Allergan Aesthetics, Concert Pharmaceuticals, Croma-Pharma, Eli Lilly, and Pfizer, and has an ownership interest in Armis Scientific, GloGetter, and Piction Health.

“Many people of color do not believe they need sunscreen,” Dr. Taylor said. But studies show that, although there may be more intrinsic protection, sunscreen is still needed.

Over 30 years ago, Halder and colleagues reported that melanin in skin of color can filter two to five times more UV radiation, and in a paper on the photoprotective role of melanin, Kaidbey and colleagues found that skin types V and VI had an intrinsic SPF of 13 when compared with those who have lighter complexions, which had an SPF of 3.

Sunburns seem to occur less frequently in people with skin of color, but that may be because erythema is less apparent in people with darker skin tones or because of differences in personal definitions of sunburn, Dr. Taylor said.

“Skin of color can and does sustain sunburns and sunscreen will help prevent that,” she said, adding that a recommendation of an SPF 30 is likely sufficient for these patients. Dr. Taylor noted that sunscreens for patients with darker skin often cost substantially more than those for lighter skin, and that should be considered in recommendations.

Tinted sunscreens

Dr. Taylor said that, while broad-spectrum photostable sunscreens protect against UVB and UVA 2, they don’t protect from visible light and UVA1. Two methods to add that protection are using inorganic tinted sunscreens that contain iron oxide or pigmentary titanium dioxide. Dr. Taylor was a coauthor of a practical guide to tinted sunscreens published in 2022.

“For iron oxide, we want a concentration of 3% or greater,” she said, adding that the percentage often is not known because if it is contained in a sunscreen, it is listed as an inactive ingredient.

Another method to address visible light and UVA1 is the use of antioxidant-containing sunscreens with vitamin E, vitamin C, or licochalcone A, Dr. Taylor said.

During the question-and-answer period following her presentation, Amit Pandya, MD, adjunct professor of dermatology at University of Texas Southwestern Medical Center, Dallas, asked why “every makeup, every sunscreen, just says iron oxide,” since it is known that visible light will cause pigmentation, especially in those with darker skin tones.

He urged pushing for a law that would require listing the percentage of iron oxide on products to assure it is sufficient, according to what the literature recommends.

Conference Chair Pearl Grimes, MD, director of the Vitiligo and Pigmentation Institute of Southern California, Los Angeles, said that she recommends tinted sunscreens almost exclusively for her patients, but those with darker skin colors struggle to match color.

Dr. Taylor referred to an analysis published in 2022 of 58 over-the counter sunscreens, which found that only 38% of tinted sunscreens was available in more than one shade, “which is a problem for many of our patients.” She said that providing samples with different hues and tactile sensations may help patients find the right product.

CHICAGO – Sunscreen recommendations are most effective when a multitude of factors are considered, Susan C. Taylor, MD, said during a presentation on personal photoprotection at the inaugural Pigmentary Disorders Exchange Symposium.

Among the first factors physicians should consider before recommending sunscreen are a patient’s Fitzpatrick skin type, risks for burning or tanning, underlying skin disorders, and medications the patient is taking, Dr. Taylor, professor of dermatology at the University of Pennsylvania, Philadelphia, said at the meeting, provided by MedscapeLIVE! If patients are on hypertensives, for example, medications can make them more photosensitive.

Consider skin type

Dr. Taylor said she was dismayed by the results of a recent study, which found that 43% of dermatologists who responded to a survey reported that they never, rarely, or only sometimes took a patient’s skin type into account when making sunscreen recommendations. The article is referenced in a 2022 expert panel consensus paper she coauthored on photoprotection “for skin of all color.” But she pointed out that considering skin type alone is inadequate.

Questions for patients in joint decision-making should include lifestyle and work choices such as whether they work inside or outside, and how much sun exposure they get in a typical day. Heat and humidity levels should also be considered as should a patient’s susceptibility to dyspigmentation. “That could be overall darkening of the skin, mottled hyperpigmentation, actinic dyspigmentation, and, of course, propensity for skin cancer,” she said.
 

Use differs by race

Dr. Taylor, who is also vice chair for diversity, equity and inclusion in the department of dermatology at the University of Pennsylvania, pointed out that sunscreen use differs considerably by race.

In study of 8,952 adults in the United States who reported that they were sun sensitive found that a subset of adults with skin of color were significantly less likely to use sunscreen when compared with non-Hispanic White adults: Non-Hispanic Black (adjusted odds ratio, 0.43); non-Hispanic Asian (aOR. 0.54); and Hispanic (aOR, 0.70) adults.

In the study, non-Hispanic Black and Hispanic adults were significantly less likely to use sunscreens with an SPF greater than 15. In addition, non-Hispanic Black, non-Hispanic Asian, and Hispanic adults were significantly more likely than non-Hispanic Whites to wear long sleeves when outside. Such differences are important to keep in mind when advising patients about sunscreens, she said.
 

Protection for lighter-colored skin

Dr. Taylor said that, for patients with lighter skin tones, “we really want to protect against ultraviolet B as well as ultraviolet A, particularly ultraviolet A2. Ultraviolet radiation is going to cause DNA damage.” Patients with Fitzpatrick skin types I, II, or III are most susceptible to the effects of UVB with sunburn inflammation, which will cause erythema and tanning, and immunosuppression.

“For those who are I, II, and III, we do want to recommend a broad-spectrum, photostable sunscreen with a critical wavelength of 370 nanometers, which is going to protect from both UVB and UVA2,” she said.

Sunscreen recommendations are meant to be paired with advice to avoid midday sun from 10 a.m. to 2 p.m., wearing protective clothing and accessories, and seeking shade, she noted.

Dr. Taylor said, for those patients with lighter skin who are more susceptible to photodamage and premature aging, physicians should recommend sunscreens that contain DNA repair enzymes such as photolyases and sunscreens that contain antioxidants that can prevent or reverse DNA damage. “The exogenous form of these lyases have been manufactured and added to sunscreens,” Dr. Taylor said. “They’re readily available in the United States. That is something to consider for patients with significant photodamage.”

Retinoids can also help alleviate or reverse photodamage, she added.

Programmed cell death protein 1 (PD-1) inhibitors have been widely used in the treatment of various cancers. Programmed cell death-ligand 1 (PD-L1) and programmed cell death-ligand 2 located on cancer cells will bind to PD-1 receptors on T cells and suppress them, which will prevent cancer cell destruction. Programmed cell death protein 1 inhibitors block the binding of PD-L1 to cancer cells, which then prevents T-cell immunosuppression.¹ However, cutaneous adverse effects have been associated with PD-1 inhibitors. Dermatitis associated with PD-1 inhibitor therapy occurs more frequently in patients with cutaneous tumors such as melanoma compared to those with head and neck cancers.² Curry et al¹ reported that treatment with an immune checkpoint blockade can lead to immune-related adverse effects, most commonly affecting the gastrointestinal tract, liver, and skin. The same report cited dermatologic toxicity as an adverse effect in approximately 39% of patients treated with anti–PD-1 and approximately 17% of anti–PD-L1.¹ The 4 main categories of dermatologic toxicities to immunotherapies in general include inflammatory disorders, immunobullous disorders, alterations of keratinocytes, and alteration of melanocytes. The most common adverse effects from the use of the PD-1 inhibitor nivolumab were skin rashes, not otherwise specified (14%–20%), pruritus (13%–18%), and vitiligo (~8%).¹ Of the cutaneous dermatitic reactions to PD-1 and PD-L1 inhibitors that were biopsied, the 2 most common were lichenoid dermatitis and spongiotic dermatitis.² Seldomly, there have been reports of keratoacanthomas (KAs) in association with anti–PD-1 therapy.³

A KA is a common skin tumor that appears most frequently as a solitary lesion and is thought to arise from the hair follicle.⁴ It resembles squamous cell carcinoma and commonly regresses within months without intervention. Exposure to UV light is a known risk factor for the development of KAs.

Eruptive KAs have been found in association with 10 cases of various cancers treated with the PD-1 inhibitors pembrolizumab and nivolumab.³ Multiple lesions on photodistributed areas of the body were reported in all 10 cases. Various treatments were used in these 10 cases—doxycycline and niacinamide, electrodesiccation and curettage, clobetasol ointment and/or intralesional triamcinolone, cryotherapy, imiquimod, or no treatment—as well as the cessation of PD-1 inhibitor therapy, with 4 cases continuing therapy and 6 cases discontinuing therapy. Nine cases regressed by 6 months; electrodesiccation and curettage of the lesions was used in the tenth case.³ We report a case of eruptive KA after 1 cycle of nivolumab therapy for metastatic melanoma.

A 79-year-old woman with stage III melanoma presented to her dermatologist after developing generalized pruritic lichenoid eruptions involving the torso, arms, and legs, as well as erosions on the lips, buccal mucosa, and palate 1 month after starting nivolumab therapy. The patient initially presented to dermatology with an irregularly shaped lesion on the left upper back 3 months prior. Biopsy results at that time revealed a diagnosis of malignant melanoma, lentigo maligna type. The lesion was 1.5-mm thick and classified as Clark level IV with a mitotic count of 6 per mm². Molecular genetic studies showed expression of PD-L1 and no expression of c-KIT. The patient underwent wide local excision, and a sentinel lymph node biopsy was positive. Positron emission tomography did not show any hypermetabolic lesions, and magnetic resonance imaging did not indicate brain metastasis. The patient underwent an axillary dissection, which did not show any residual melanoma. She was started on adjuvant immunotherapy with intravenous nivolumab 480 mg monthly and developed pruritic crusted lesions on the arms, legs, and torso 1 month later, which prompted follow-up to dermatology.

At the current presentation 4 months after the onset of lesions, physical examination revealed lichenoid patches with serous crusting that were concentrated on the torso but also affected the arms and legs. She developed erosions on the upper and lower lips, buccal mucosa, and hard and soft palates, as well as painful, erythematous, dome-shaped papules and nodules on the legs (Figure 1). Her oncologist previously had initiated treatment at the onset of the lesions with clobetasol cream and valacyclovir for the lesions, but the patient showed no improvement.

Four months after the onset of the lesions, the patient was re-referred to her dermatologist, and a biopsy was performed on the left lower leg that showed squamous cell carcinoma, KA type. Additionally, flat erythematous patches were seen on the legs that were consistent with a lichenoid drug eruption. Two weeks later, she was started on halobetasol propionate ointment 0.05% for treatment of the KAs. At 2-week follow-up, 5 months after the onset of the lesions, the patient showed no signs of improvement. An oral prednisone taper of 60 mg for 3 days, 40 mg for 3 days, and then 20 mg daily for a total of 4 weeks was started to treat the lichenoid dermatitis and eruptive KAs. At the next follow-up 6.5 months following the first eruptive KAs, she was no longer using topical or oral steroids, she did not have any new eruptive KAs, and old lesions showed regression (Figure 2). The patient still experienced postinflammatory erythema and hyperpigmentation at the location of the KAs but showed improvement of the lichenoid drug eruption.

We describe a case of eruptive KAs after use of a PD-1 inhibitor for treatment of melanoma. Our patient developed eruptive KAs after only 1 nivolumab treatment. Another report described onset of eruptive KAs after 1 month of nivolumab infusions.³ The KAs experienced by our patient took 6.5 months to regress, which is unusual compared to other case reports in which the KAs self-resolved within a few months, though one other case described lesions that persisted for 6 months.³

Our patient was treated with topical steroids and an oral steroid taper for the concomitant lichenoid drug eruption. It is unknown if the steroids affected the course of the KAs or if they spontaneously regressed on their own. Freites-Martinez et al⁵ described that regression of KAs may be related to an immune response, but corticosteroids are inherently immunosuppressive. They hypothesized that corticosteroids help to temper the heightened immune response of eruptive KAs.⁵

Our patient had oral ulcers, which may have been indicative of an oral lichenoid drug eruption, as well as skin lesions representative of a cutaneous lichenoid drug eruption. This is a favorable reaction, as lichenoid dermatitis is thought to represent successful PD-1 inhibition and therefore a better response to oncologic therapies.² Comorbid lichenoid drug eruption lesions and eruptive KAs may be suggestive of increased T-cell activity,^2,6,7 though some prior case studies have reported eruptive KAs in isolation.³

Discontinuation of immunotherapy due to development of eruptive KAs presents a challenge in the treatment of underlying malignancies such as melanoma. Immunotherapy was discontinued in 7 of 11 cases due to these cutaneous reactions.³ Similarly, our patient underwent only 1 cycle of immunotherapy before developing eruptive KAs and discontinuing PD-1 inhibitor therapy. If we are better able to treat eruptive KAs, then patients can remain on immunotherapy to treat underlying malignancies. Crow et al⁸ showed improvement in lesions when 3 patients with eruptive KAs were treated with hydroxychloroquine; the Goeckerman regimen consisting of steroids, UVB phototherapy, and crude coal tar; and Unna boots with zinc oxide and compression stockings. The above may be added to a list of possible treatments to consider for hastening the regression of eruptive KAs.

Our patient’s clinical course was similar to reports on the regressive nature of eruptive KAs within 6 months after initial eruption. Although it is likely that KAs will regress on their own, treatment modalities that speed up recovery are a future source for research.

SEATTLE – The majority of patients who underwent a teledermatology follow-up after Mohs micrographic surgery reported that they preferred it to in-person follow up, according to new findings.

In addition, nearly all patients surveyed (91.4%) were willing to go through electronic follow-up again.

“A big takeaway from our study is that streamlining this process is really essential for successful implementation,” said study author Laura Rezac, MD, a PGY IV dermatology resident at the University of Mississippi, Jackson. “This study demonstrated the flexibility and convenience for both patients and surgeons and can serve as a prototype for future innovation.”

The study results were presented at the annual meeting of the American College of Mohs Surgery.

The role of telehealth has rapidly expanded over the past decade, with its use accelerating during the COVID-19 pandemic and transforming into an indispensable resource. It can be synchronous, Dr. Rezac explained, which is when telehealth happens in live, real-time settings where the patient interacts with a clinician. This usually occurs via phone or video, and providers and patients communicate directly.

Conversely, asynchronous telehealth, also known as “store-and-forward,” is often used for patient intake or follow-up care. For example, in dermatology, a patient can send a photo of a skin condition that is then reviewed by a dermatologist later.

“A pilot survey regarding the adoption of telemedicine in Mohs surgery found that, although most dermatologic surgeons felt that it can play a role, most said that they didn’t plan on using it after the pandemic,” said Dr. Rezac.

The survey, which was reported by this news organization, found that 80% of surveyed surgeons said that they turned to telemedicine during the pandemic, compared with just 23% who relied on the technology prior to the pandemic.

There were numerous perceived barriers to the use of telemedicine, and the one most commonly cited was the uncertainty of how telemedicine fits in the workflow of clinical practice. Other limitations reported were for physical exams (88%), patient response and training (57%), reimbursement concerns (50%), implementation of the technology (37%), regulations such as HIPAA (24%), training of staff (17%), and licensing (8%).

“The survey did identify one key use of telemedicine in Mohs and that was for [postoperative] visits,” she said. “But thus far, a postoperative evaluation after Mohs via an integrated asynchronous ‘store and forward’ teledermatology platform has not yet been evaluated.”

In the study, Dr. Rezac and colleagues sought to evaluate feasibility and efficacy, as well as patient attitudes, using a telemedicine platform for postoperative follow-up. A total of 163 patients who were treated with Mohs at a single academic institution during the 9-month study period (December 2021 through August 2022) responded to a survey and elected to participate in postoperative follow-up using telemedicine.

Dr. Rezac explained how their procedure was implemented for the patient. “On the day of the follow-up, the patient receives a text with a link that takes them to the MyChart website or app on their phone,” she said. “Once they log in, they see that they have a message telling them that they have a teledermatology message waiting for them. When they view it, they are taken to the curated message with instructions and a phone call if they need assistance, and then at the bottom, it shows they have a task to complete, which is the questionnaire.”

The patient will then be prompted to upload photos, which can be taken with their phone camera. The next step is to answer questions regarding the surgical site or pain concerns, and finally, patients are asked to respond to a few short questions about this type of follow-up. Once submitted, then they wait to be contacted by the surgeon.

On the surgeon’s side, these answers come into their EPIC inbox, and they can respond via a MyChart message.

Patient response was overwhelmingly positive, Dr. Rezac noted. Of the patients, 80.4% found the electronic surgery follow-up process to be “easy” or “very easy,” while only 4% found it “difficult” or “very difficult,” she said. “Also, 75.5% preferred electronic follow-up while 17.2% preferred in-person follow-up.”

There were limitations to this study, primarily that the asynchronous method does reduce live interaction, which could be an issue, depending on person’s needs, she pointed out. “But it is easy to schedule a phone call or video call or office visit.”

“The universal barrier is how to adopt it into the workflow, which includes training of staff,” she continued, “But this was a very streamlined process and gave very detailed instructions to the staff. Additionally, widespread use is limited to dermatological proficiency and access, and patients have to be amenable to it, so there is a selection bias since these patients chose to participate.”

Asked to comment on the study, Vishal Patel, MD, director of cutaneous oncology at George Washington University in Washington, said: “The COVID pandemic changed how practices and providers considered follow-up visits for small routine matters. Postoperative visits are often simple and do not require an in-depth, in-person evaluation.” Dr. Patel was not involved with this research.

“This study highlights the comfort of the vast majority of patients to have follow-up postoperative visits conducted via teledermatology – an approach that can help cut overall costs and also increase access for patients who are more in need of in-office care,” he added.

No external funding of the study was reported. Dr. Rezac reported no relevant financial relationships. Dr. Patel is a consultant for Sanofi, Regeneron, and Almirall.

SEATTLE – The majority of patients who underwent a teledermatology follow-up after Mohs micrographic surgery reported that they preferred it to in-person follow up, according to new findings.

In addition, nearly all patients surveyed (91.4%) were willing to go through electronic follow-up again.

“A big takeaway from our study is that streamlining this process is really essential for successful implementation,” said study author Laura Rezac, MD, a PGY IV dermatology resident at the University of Mississippi, Jackson. “This study demonstrated the flexibility and convenience for both patients and surgeons and can serve as a prototype for future innovation.”

SEATTLE – At least for now, the number of physicians trained to perform Mohs surgery is not only stable but appears to be increasing. New findings show that the number of new fellows offsets the attrition rate and that has been the case for the past 5 years.

Using CMS billing codes as a surrogate, the researchers found that there was a steady increase in the number of physicians who billed from 2015 to 2020. With the exception of 2020, which was the height of the COVID-19 pandemic, the number of times that a specific code was billed for increased on average by 4.7% annually.

“Thus, if the attrition rate remains stable, even with changes in board certification and potential payer eligibility restrictions, the number of physicians will continue to increase,” study author Ji Won Ahn, MD, who specializes in dermatology and Mohs surgery at University of Pittsburgh Medical Center, said at the annual meeting of the American College of Mohs Surgery, where she presented the results.

The growth in the number of Mohs surgeons has been fueled by several factors, including a rising incidence of skin cancer as well as the superior cure rates and cosmetic outcomes with the procedure. Reimbursement has been favorable and training pathways have expanded. A 2019 retrospective study reported that there were 2,240 dermatologists who performed Mohs surgery in the United States, with nearly all of them (94.6%) residing in metropolitan areas.

Dr. Ahn explained that it was important to define the workforce because of several new factors that will be affecting it in the future. “With the establishment of Micrographic Surgery and Dermatologic Oncology [MSDO] board certification that went into effect 2 years ago, potential future payer eligibility restrictions may be coming,” she said. “The adequacy of the Mohs surgery workforce is an important consideration.”

Another issue is that new board certification will be limited to fellowship-trained physicians after the first 5 years. “We wanted to compare these numbers with the fellowship numbers,” she said. “Although fellowship numbers are something that the college potentially has the power to change.”

Dr. Ahn and colleagues used the Centers for Medicare & Medicaid Services database to evaluate the use of the Current Procedural Terminology (CPT) code 17311, which is one of the most common billing codes for Mohs micrographic technique. Looking at data from 2015-2020, they found that there was an annual increase in the number of unique national provider identifiers (NPIs) billing for 17311, at an average rate of 75.6 per year.

The total number of times that 17311 was billed also increased from 2015 to 2019 at an average rate of 4.7% per year but declined in 2020 by 8.4%. “Overall, there was an average of 135 new NPIs that appeared and an average of 59.4 NPIs that stopped billing for 17311,” thus, an attrition rate of 59 surgeons, Dr. Ahn explained.

She emphasized that notably, the number of approved MSDO fellowship spots has remained stable since 2016 and is about 92 to 93 per year. “There are about 135 new surgeons and about two-thirds are new fellowship graduates,” she said.

The researchers were also interested in seeing how saturated each surgeon was and looked at the approximate number of cases that they were handling.

Of the physicians who billed 17311 through CMS, over 26% billed less than 100 times and more than 45% billed less than 200 times, and over 80% billed less than 500 times.

“One might be able to conclude that there might be some potential flexibility depending on the future need for surgeons,” she said.

The study was limited by several factors, one being that the researchers looked only at CPT code 17311 and not other designated codes for Mohs surgery. Other factors such as staff and space limitations were not accounted for since only billing data were used.

Dr. Ahn and her team are going to continue their work, and the next steps are to look at geographic trends and monitor for insurance network eligibility changes. “We are currently doing a workforce survey so we can better understand our current workforce rather than just historical data,” she concluded.

Asked to comment on the results, Vishal Patel, MD, assistant professor of dermatology and director of the cutaneous oncology program at George Washington University, Washington, who was not involved with the study, noted that the increase in the “billing rates of the first stage of Mohs micrographic surgery highlights not only the growing skin cancer epidemic, but also the number of providers who are providing these services. This underscores the importance of standardized training guidelines and board certifications of Mohs micrographic surgeons to assure high levels of patient care and the appropriate use of Mohs micrographic surgery,” he said.

The number of cancer survivors who report functional limitation has more than doubled in 20 years, according to a research letter published in JAMA Oncology.

Vishal Patel, BS, a student at the Dell Medical School at The University of Texas at Austin, and colleagues identified 51,258 cancer survivors from the National Health Interview Survey, representing a weighted population of approximately 178.8 million from 1999 to 2018.

Most survivors were women (60.2%) and were at least 65 years old (55.4%). In 1999, 3.6 million weighted survivors reported functional limitation. In 2018, the number increased to 8.2 million, a 2.25-fold increase.

The number of survivors who reported no limitations also increased, but not by as much. That group grew 1.34-fold during the study period.

For context, “the 70% prevalence of functional limitation among survivors in 2018 is nearly twice that of the general population,” the authors wrote.
 

Patients surveyed on function

Functional limitation was defined as “self-reported difficulty performing any of 12 routine physical or social activities without assistance.” Examples of the activities included difficulty sitting for more than 2 hours, difficulty participating in social activities or difficulty pushing or pulling an object the size of a living room chair.

Over the 2 decades analyzed, the adjusted prevalence of functional limitation was highest among survivors of pancreatic cancer (80.3%) and lung cancer (76.5%). Prevalence was lowest for survivors of melanoma (62.2%), breast (61.8%) and prostate (59.5%) cancers.
 

Not just a result of living longer

Mr. Patel told this publication that one assumption people might make when they read these results is that people are just living longer with cancer and losing functional ability accordingly.

“But, in fact, we found that the youngest [– those less than 65 years–] actually contributed to this trend more than the oldest people, which means it’s not just [happening], because people are getting older,” he said.

Hispanic and Black individuals had disproportionately higher increases in functional limitation; percentage point increases over the 2 decades were 19.5 for Black people, 25.1 for Hispanic people and 12.5 for White people. There may be a couple of reasons for that, Mr. Patel noted.

Those who are Black or Hispanic tend to have less access to cancer survivorship care for reasons including insurance status and historic health care inequities, he noted.

“The other potential reason is that they have had less access to cancer care historically. And if, 20 years ago Black and Hispanic individuals didn’t have access to some chemotherapies, and now they do, maybe it’s the increased access to care that’s causing these functional limitations. Because chemotherapy can sometimes be very toxic. It may be sort of a catch-up toxicity,” he said.
 

Quality of life beyond survivorship

Mr. Patel said the results seem to call for building on improved survival rates by tracking and improving function.

“It’s good to celebrate that there are more survivors. But now that we can keep people alive longer, maybe we can shift gears to improving their quality of life,” he said.

The more-than-doubling of functional limitations over 2 decades “is a very sobering trend,” he noted, while pointing out that the functional limitations applied to 8 million people in the United States – people whose needs are not being met.

There’s no sign of the trend stopping, he continued. “We saw no downward trend, only an upward trend.”

Increasingly, including functionality as an endpoint in cancer trials, in addition to improvements in mortality, is one place to start, he added.

“Our findings suggest an urgent need for care teams to understand and address function, for researchers to evaluate function as a core outcome in trials, and for health systems and policy makers to reimagine survivorship care, recognizing the burden of cancer and its treatment on physical, psychosocial, and cognitive function,” the authors wrote in their paper. Limitations of the study include the potential for recall bias, lack of cancer staging or treatment information, and the subjective perception of function.

The number of cancer survivors who report functional limitation has more than doubled in 20 years, according to a research letter published in JAMA Oncology.

Vishal Patel, BS, a student at the Dell Medical School at The University of Texas at Austin, and colleagues identified 51,258 cancer survivors from the National Health Interview Survey, representing a weighted population of approximately 178.8 million from 1999 to 2018.

Most survivors were women (60.2%) and were at least 65 years old (55.4%). In 1999, 3.6 million weighted survivors reported functional limitation. In 2018, the number increased to 8.2 million, a 2.25-fold increase.

The number of survivors who reported no limitations also increased, but not by as much. That group grew 1.34-fold during the study period.

For context, “the 70% prevalence of functional limitation among survivors in 2018 is nearly twice that of the general population,” the authors wrote.
 

Patients surveyed on function

Functional limitation was defined as “self-reported difficulty performing any of 12 routine physical or social activities without assistance.” Examples of the activities included difficulty sitting for more than 2 hours, difficulty participating in social activities or difficulty pushing or pulling an object the size of a living room chair.

Over the 2 decades analyzed, the adjusted prevalence of functional limitation was highest among survivors of pancreatic cancer (80.3%) and lung cancer (76.5%). Prevalence was lowest for survivors of melanoma (62.2%), breast (61.8%) and prostate (59.5%) cancers.
 

Not just a result of living longer

Mr. Patel told this publication that one assumption people might make when they read these results is that people are just living longer with cancer and losing functional ability accordingly.

“But, in fact, we found that the youngest [– those less than 65 years–] actually contributed to this trend more than the oldest people, which means it’s not just [happening], because people are getting older,” he said.

Hispanic and Black individuals had disproportionately higher increases in functional limitation; percentage point increases over the 2 decades were 19.5 for Black people, 25.1 for Hispanic people and 12.5 for White people. There may be a couple of reasons for that, Mr. Patel noted.

Those who are Black or Hispanic tend to have less access to cancer survivorship care for reasons including insurance status and historic health care inequities, he noted.

“The other potential reason is that they have had less access to cancer care historically. And if, 20 years ago Black and Hispanic individuals didn’t have access to some chemotherapies, and now they do, maybe it’s the increased access to care that’s causing these functional limitations. Because chemotherapy can sometimes be very toxic. It may be sort of a catch-up toxicity,” he said.
 

Quality of life beyond survivorship

Mr. Patel said the results seem to call for building on improved survival rates by tracking and improving function.

“It’s good to celebrate that there are more survivors. But now that we can keep people alive longer, maybe we can shift gears to improving their quality of life,” he said.

The more-than-doubling of functional limitations over 2 decades “is a very sobering trend,” he noted, while pointing out that the functional limitations applied to 8 million people in the United States – people whose needs are not being met.

There’s no sign of the trend stopping, he continued. “We saw no downward trend, only an upward trend.”

Increasingly, including functionality as an endpoint in cancer trials, in addition to improvements in mortality, is one place to start, he added.

“Our findings suggest an urgent need for care teams to understand and address function, for researchers to evaluate function as a core outcome in trials, and for health systems and policy makers to reimagine survivorship care, recognizing the burden of cancer and its treatment on physical, psychosocial, and cognitive function,” the authors wrote in their paper. Limitations of the study include the potential for recall bias, lack of cancer staging or treatment information, and the subjective perception of function.

Communities with easy access to fast food were 77% more likely to have high levels of obesity-related cancer mortality, based on data from a new cross-sectional study of more than 3,000 communities.

Although increased healthy eating has been associated with reduced risk of obesity and with reduced cancer incidence and mortality, access to healthier eating remains a challenge in communities with less access to grocery stores and healthy food options (food deserts) and/or easy access to convenience stores and fast food (food swamps), Malcolm Seth Bevel, PhD, of the Medical College of Georgia, Augusta, and colleagues, wrote in their paper, published in JAMA Oncology.

In addition, data on the association between food deserts and swamps and obesity-related cancer mortality are limited, they said.

“We felt that the study was important given the fact that obesity is an epidemic in the United States, and multiple factors contribute to obesity, especially adverse food environments,” Dr. Bevel said in an interview. “Also, I lived in these areas my whole life, and saw how it affected underserved populations. There was a story that needed to be told, so we’re telling it,” he said in an interview.

In a study, the researchers analyzed food access and cancer mortality data from 3,038 counties across the United States. The food access data came from the U.S. Department of Agriculture Food Environment Atlas (FEA) for the years 2012, 2014, 2015, 2017, and 2020. Data on obesity-related cancer mortality came from the Centers for Disease Control and Prevention for the years from 2010 to 2020.

Food desert scores were calculated through data from the FEA, and food swamp scores were based on the ratio of fast-food restaurants and convenience stores to grocery stores and farmers markets in a modification of the Retail Food Environment Index score.

The researchers used an age-adjusted, multiple regression model to determine the association between food desert and food swamp scores and obesity-related cancer mortality rates. Higher food swamp and food desert scores (defined as 20.0 to 58.0 or higher) were used to classify counties as having fewer healthy food resources. The primary outcome was obesity-related cancer mortality, defined as high or low (71.8 or higher per 100,000 individuals and less than 71.8 per 100,000 individuals, respectively).

Overall, high rates of obesity-related cancer mortality were 77% more likely in the counties that met the criteria for high food swamp scores (adjusted odds ratio 1.77). In addition, researchers found a positive dose-response relationship among three levels of both food desert scores and food swamp scores and obesity-related cancer mortality.

A total of 758 counties had obesity-related cancer mortality rates in the highest quartile. Compared to counties with low rates of obesity-related cancer mortality, counties with high rates of obesity-related cancer mortality also had a higher percentage of non-Hispanic Black residents (3.26% vs. 1.77%), higher percentage of adults older than 65 years (15.71% vs. 15.40%), higher rates of adult obesity (33.0% vs. 32.10%), and higher rates of adult diabetes (12.50% vs. 10.70%).

Possible explanations for the results include the lack of interest in grocery stores in neighborhoods with a population with a lower socioeconomic status, which can create a food desert, the researchers wrote in their discussion. “Coupled with the increasing growth rate of fast-food restaurants in recent years and the intentional advertisement of unhealthy foods in urban neighborhoods with [people of lower income], the food desert may transform into a food swamp,” they said.

The findings were limited by several factors including the study design, which did not allow for showing a causal association of food deserts and food swamps with obesity-related cancer mortality, the researchers noted. Other limitations included the use of groups rather than individuals, the potential misclassification of food stores, and the use of county-level data on race, ethnicity, and income, they wrote.

The results indicate that “food swamps appear to be a growing epidemic across the U.S., likely because of systemic issues, and should draw concern and conversation from local and state officials,” the researchers concluded.
 

Community-level investments can benefit individual health

Dr. Bevel said he was not surprised by the findings, as he has seen firsthand the lack of healthy food options and growth of unhealthy food options, especially for certain populations in certain communities. “Typically, these are people who have lower socioeconomic status, primarily non-Hispanic Black or African American or Hispanic American,” he said “I have watched people have to choose between getting fruits/vegetables versus their medications or running to fast food places to feed their families. What is truly surprising is that we’re not talking about people’s lived environment enough for my taste,” he said.  

“I hope that our data and results can inform local and state policymakers to truly invest in all communities, such as funding for community gardens, and realize that adverse food environments, including the barriers in navigating these environments, have significant consequences on real people,” said Dr. Bevel. “Also, I hope that the results can help clinicians realize that a patient’s lived environment can truly affect their obesity and/or obesity-related cancer status; being cognizant of that is the first step in holistic, comprehensive care,” he said. 

“One role that oncologists might be able to play in improving patients’ access to healthier food is to create and/or implement healthy lifestyle programs with gardening components to combat the poorest food environments that their patients likely reside in,” said Dr. Bevel. Clinicians also could consider the innovative approach of “food prescriptions” to help reduce the effects of deprived, built environments, he noted.

Looking ahead, next steps for research include determining the severity of association between food swamps and obesity-related cancer by varying factors such as cancer type, and examining any potential racial disparities between people living in these environments and obesity-related cancer, Dr. Bevel added.
 

Data provide foundation for multilevel interventions

The current study findings “raise a clarion call to elevate the discussion on food availability and access to ensure an equitable emphasis on both the importance of lifestyle factors and the upstream structural, economic, and environmental contexts that shape these behaviors at the individual level,” Karriem S. Watson, DHSc, MS, MPH, of the National Institutes of Health, Bethesda, Md., and Angela Odoms-Young, PhD, of Cornell University, Ithaca, N.Y., wrote in an accompanying editorial.

The findings provide a foundation for studies of obesity-related cancer outcomes that take the community environment into consideration, they added.

The causes of both obesity and cancer are complex, and the study findings suggest that the links between unhealthy food environments and obesity-related cancer may go beyond dietary consumption alone and extend to social and psychological factors, the editorialists noted.

“Whether dealing with the lack of access to healthy foods or an overabundance of unhealthy food, there is a critical need to develop additional research that explores the associations between obesity-related cancer mortality and food inequities,” they concluded.

The study received no outside funding. The researchers and the editorialists had no financial conflicts to disclose.

SAN DIEGO – Primary care providers can draw from a wide range of diets to give patients evidence-based advice on how to lose weight, prevent diabetes, and achieve other health goals, according to a speaker at the annual meeting of the American College of Physicians.

“Evidence from studies can help clinicians and their patients develop a successful dietary management plan and achieve optimal health,” said internist Michelle Hauser, MD, clinical associate professor at Stanford (Calif.) University. She also discussed evidence-based techniques to support patients in maintaining dietary modifications.
 

Predominantly plant‐based diets

Popular predominantly plant‐based diets include a Mediterranean diet, healthy vegetarian diet, predominantly whole-food plant‐based (WFPB) diet, and a dietary approach to stop hypertension (DASH).

The DASH diet was originally designed to help patients manage their blood pressure, but evidence suggests that it also can help adults with obesity lose weight. In contrast to the DASH diet, the Mediterranean diet is not low-fat and not very restrictive. Yet the evidence suggests that the Mediterranean diet is not only helpful for losing weight but also can reduce the risk of various chronic diseases, including obesity, type 2 diabetes, cardiovascular disease (CVD), and cancer, Dr. Hauser said. In addition, data suggest that the Mediterranean diet may reduce the risk of all-cause mortality and lower the levels of cholesterol.

“I like to highlight all these protective effects to my patients, because even if their goal is to lose weight, knowing that hard work pays off in additional ways can keep them motivated,” Dr. Hauser stated.

A healthy vegetarian diet and a WFPB diet are similar, and both are helpful in weight loss and management of total cholesterol and LDL‐C levels. Furthermore, healthy vegetarian and WFPB diets may reduce the risk of type 2 diabetes, CVD, and some cancers. Cohort study data suggest that progressively more vegetarian diets are associated with lower BMIs.

“My interpretation of these data is that predominantly plant-based diets rich in whole foods are healthful and can be done in a way that is sustainable for most,” said Dr. Hauser. However, this generally requires a lot of support at the outset to address gaps in knowledge, skills, and other potential barriers.

For example, she referred one obese patient at risk of diabetes and cardiovascular disease to a registered dietitian to develop a dietary plan. The patient also attended a behavioral medicine weight management program to learn strategies such as using smaller plates, and his family attended a healthy cooking class together to improve meal planning and cooking skills.
 

Time‐restricted feeding

There are numerous variations of time-restricted feeding, commonly referred to as intermittent fasting, but the principles are similar – limiting food intake to a specific window of time each day or week.

Although some studies have shown that time-restricted feeding may help patients reduce adiposity and improve lipid markers, most studies comparing time-restricted feeding to a calorie-restricted diet have shown little to no difference in weight-related outcomes, Dr. Hauser said.

These data suggest that time-restricted feeding may help patients with weight loss only if time restriction helps them reduce calorie intake. She also warned that time-restrictive feeding might cause late-night cravings and might not be helpful in individuals prone to food cravings.
 

Low‐carbohydrate and ketogenic diets

Losing muscle mass can prevent some people from dieting, but evidence suggests that a high-fat, very low-carbohydrate diet – also called a ketogenic diet – may help patients reduce weight and fat mass while preserving fat‐free mass, Dr. Hauser said.

The evidence regarding the usefulness of a low-carbohydrate (non-keto) diet is less clear because most studies compared it to a low-fat diet, and these two diets might lead to a similar extent of weight loss.
 

Rating the level of scientific evidence behind different diet options

Nutrition studies do no provide the same level of evidence as drug studies, said Dr. Hauser, because it is easier to conduct a randomized controlled trial of a drug versus placebo. Diets have many more variables, and it also takes much longer to observe most outcomes of a dietary change.

In addition, clinical trials of dietary interventions are typically short and focus on disease markers such as serum lipids and hemoglobin A1c levels. To obtain reliable information on the usefulness of a diet, researchers need to collect detailed health and lifestyle information from hundreds of thousands of people over several decades, which is not always feasible. “This is why meta-analyses of pooled dietary study data are more likely to yield dependable findings,” she noted.
 

Getting to know patients is essential to help them maintain diet modifications

When developing a diet plan for a patient, it is important to consider the sustainability of a dietary pattern. “The benefits of any healthy dietary change will only last as long as they can be maintained,” said Dr. Hauser. “Counseling someone on choosing an appropriate long-term dietary pattern requires getting to know them – taste preferences, food traditions, barriers, facilitators, food access, and time and cost restrictions.”

In an interview after the session, David Bittleman, MD, an internist at Veterans Affairs San Diego Health Care System, agreed that getting to know patients is essential for successfully advising them on diet.

“I always start developing a diet plan by trying to find out what [a patient’s] diet is like and what their goals are. I need to know what they are already doing in order to make suggestions about what they can do to make their diet healthier,” he said.

SAN DIEGO – Primary care providers can draw from a wide range of diets to give patients evidence-based advice on how to lose weight, prevent diabetes, and achieve other health goals, according to a speaker at the annual meeting of the American College of Physicians.

“Evidence from studies can help clinicians and their patients develop a successful dietary management plan and achieve optimal health,” said internist Michelle Hauser, MD, clinical associate professor at Stanford (Calif.) University. She also discussed evidence-based techniques to support patients in maintaining dietary modifications.
 

Predominantly plant‐based diets

Popular predominantly plant‐based diets include a Mediterranean diet, healthy vegetarian diet, predominantly whole-food plant‐based (WFPB) diet, and a dietary approach to stop hypertension (DASH).

The DASH diet was originally designed to help patients manage their blood pressure, but evidence suggests that it also can help adults with obesity lose weight. In contrast to the DASH diet, the Mediterranean diet is not low-fat and not very restrictive. Yet the evidence suggests that the Mediterranean diet is not only helpful for losing weight but also can reduce the risk of various chronic diseases, including obesity, type 2 diabetes, cardiovascular disease (CVD), and cancer, Dr. Hauser said. In addition, data suggest that the Mediterranean diet may reduce the risk of all-cause mortality and lower the levels of cholesterol.

“I like to highlight all these protective effects to my patients, because even if their goal is to lose weight, knowing that hard work pays off in additional ways can keep them motivated,” Dr. Hauser stated.

A healthy vegetarian diet and a WFPB diet are similar, and both are helpful in weight loss and management of total cholesterol and LDL‐C levels. Furthermore, healthy vegetarian and WFPB diets may reduce the risk of type 2 diabetes, CVD, and some cancers. Cohort study data suggest that progressively more vegetarian diets are associated with lower BMIs.

“My interpretation of these data is that predominantly plant-based diets rich in whole foods are healthful and can be done in a way that is sustainable for most,” said Dr. Hauser. However, this generally requires a lot of support at the outset to address gaps in knowledge, skills, and other potential barriers.

For example, she referred one obese patient at risk of diabetes and cardiovascular disease to a registered dietitian to develop a dietary plan. The patient also attended a behavioral medicine weight management program to learn strategies such as using smaller plates, and his family attended a healthy cooking class together to improve meal planning and cooking skills.
 

Time‐restricted feeding

There are numerous variations of time-restricted feeding, commonly referred to as intermittent fasting, but the principles are similar – limiting food intake to a specific window of time each day or week.

Although some studies have shown that time-restricted feeding may help patients reduce adiposity and improve lipid markers, most studies comparing time-restricted feeding to a calorie-restricted diet have shown little to no difference in weight-related outcomes, Dr. Hauser said.

These data suggest that time-restricted feeding may help patients with weight loss only if time restriction helps them reduce calorie intake. She also warned that time-restrictive feeding might cause late-night cravings and might not be helpful in individuals prone to food cravings.
 

Low‐carbohydrate and ketogenic diets

Losing muscle mass can prevent some people from dieting, but evidence suggests that a high-fat, very low-carbohydrate diet – also called a ketogenic diet – may help patients reduce weight and fat mass while preserving fat‐free mass, Dr. Hauser said.

The evidence regarding the usefulness of a low-carbohydrate (non-keto) diet is less clear because most studies compared it to a low-fat diet, and these two diets might lead to a similar extent of weight loss.
 

Rating the level of scientific evidence behind different diet options

Nutrition studies do no provide the same level of evidence as drug studies, said Dr. Hauser, because it is easier to conduct a randomized controlled trial of a drug versus placebo. Diets have many more variables, and it also takes much longer to observe most outcomes of a dietary change.

In addition, clinical trials of dietary interventions are typically short and focus on disease markers such as serum lipids and hemoglobin A1c levels. To obtain reliable information on the usefulness of a diet, researchers need to collect detailed health and lifestyle information from hundreds of thousands of people over several decades, which is not always feasible. “This is why meta-analyses of pooled dietary study data are more likely to yield dependable findings,” she noted.
 

Getting to know patients is essential to help them maintain diet modifications

When developing a diet plan for a patient, it is important to consider the sustainability of a dietary pattern. “The benefits of any healthy dietary change will only last as long as they can be maintained,” said Dr. Hauser. “Counseling someone on choosing an appropriate long-term dietary pattern requires getting to know them – taste preferences, food traditions, barriers, facilitators, food access, and time and cost restrictions.”

In an interview after the session, David Bittleman, MD, an internist at Veterans Affairs San Diego Health Care System, agreed that getting to know patients is essential for successfully advising them on diet.

“I always start developing a diet plan by trying to find out what [a patient’s] diet is like and what their goals are. I need to know what they are already doing in order to make suggestions about what they can do to make their diet healthier,” he said.

Adults with cancer experienced significant reductions in pain after taking medicinal cannabis, in a study.

Physician-prescribed cannabis, particularly cannabinoids, has been shown to ease cancer-related pain in adult cancer patients, who often find inadequate pain relief from medications including opioids, Saro Aprikian, MSc, a medical student at the Royal College of Surgeons, Dublin, and colleagues, wrote in their paper.

However, real-world data on the safety and effectiveness of cannabis in the cancer population and the impact on use of other medications are lacking, the researchers said.

In the study, published in BMJ Supportive & Palliative Care, the researchers reviewed data from 358 adults with cancer who were part of a multicenter cannabis registry in Canada between May 2015 and October 2018.

The average age of the patients was 57.6 years, and 48% were men. The top three cancer diagnoses in the study population were genitorurinary, breast, and colorectal.

Pain was the most common reason for obtaining a medical cannabis prescription, cited by 72.4% of patients.

Data were collected at follow-up visits conducted every 3 months over 1 year. Pain was assessed via the Brief Pain Inventory (BPI) and revised Edmonton Symptom Assessment System (ESAS-r) questionnaires and compared to baseline values. Patients rated their pain intensity on a sliding scale of 0 (none) to 10 (worst possible). Pain relief was rated on a scale of 0% (none) to 100% (complete).

Compared to baseline scores, patients showed significant decreases at 3, 6 and 9 months for BPI worst pain (5.5 at baseline, 3.6 for 3, 6, and 9 months) average pain (4.1 at baseline, 2.4, 2.3, and 2.7 for 3, 6, and 9 months, respectively), overall pain severity (2.7 at baseline, 2.3, 2.3, and 2.4 at 3, 6, and 9 months, respectively), and pain interference with daily life (4.3 at baseline, 2.4, 2.2, and 2.4 at 3, 6, and 9 months, respectively; P less than .01 for all four pain measures).

“Pain severity as reported in the ESAS-r decreased significantly at 3-month, 6-month and 9-month follow-ups,” the researchers noted.

In addition, total medication burden based on the medication quantification scale (MQS) and morphine equivalent daily dose (MEDD) were recorded at 3, 6, 9, and 12 months. MQS scores decreased compared to baseline at 3, 6, 9, and 12 months in 10%, 23.5%, 26.2%, and 31.6% of patients, respectively. Also compared with baseline, 11.1%, 31.3%, and 14.3% of patients reported decreases in MEDD scores at 3, 6, and 9 months, respectively.

Overall, products with equal amounts of active ingredients tetrahydrocannabinol (THC) and cannabidiol (CBD) were more effective than were those with a predominance of either THC or CBD, the researchers wrote.

Medical cannabis was well-tolerated; a total of 15 moderate to severe side effects were reported by 11 patients, 13 of which were minor. The most common side effects were sleepiness and fatigue, and five patients discontinued their medical cannabis because of side effects. The two serious side effects reported during the study period – pneumonia and a cardiovascular event – were deemed unlikely related to the patients’ medicinal cannabis use.

The findings were limited by several factors, including the observational design, which prevented conclusions about causality, the researchers noted. Other limitations included the loss of many patients to follow-up and incomplete data on other prescription medications in many cases.

The results support the use of medical cannabis by cancer patients as an adjunct pain relief strategy and a way to potentially reduce the use of other medications such as opioids, the authors concluded.

The study was supported by the Canadian Consortium for the Investigation of Cannabinoids, Collège des Médecins du Québec, and the Canopy Growth Corporation. The researchers had no financial conflicts to disclose.
