Nonmelanoma Skin Cancer

Delivering microdose incision-site injections of clindamycin significantly reduced the rate of surgical site infections (SSIs) in skin cancer surgery.

However, prophylaxis with flucloxacillin did not significantly lower SSI rates, compared with not using incision site antibiotics.

The rate of postoperative SSIs was 2.1% in the clindamycin arm, vs. 5.7% in the control arm and 5.3% in the flucloxacillin arm.

“Based on these results, we recommend the routine adoption of incisional microdosed clindamycin for patients undergoing skin cancer surgery,” Maple Goh, MBChB, of the Auckland Regional Plastic and Reconstructive Surgery Unit, Auckland, New Zealand, and the coauthors conclude. “This strategy appears suitable for widespread implementation because of the magnitude of the effect observed and the absence of adverse events.”

The study was published online in JAMA Surgery.

Skin cancer surgery carries a high risk of SSIs, which represent costly yet largely preventable complications of surgery. Despite the risk, there’s a lack of evidence from randomized clinical trials of the role of antibiotic prophylaxis in reducing SSI rates among patients undergoing skin cancer surgery. Previous studies have investigated incisional antibiotic prophylaxis to reduce SSIs with Mohs micrographic surgery, but these surgeries represent a relatively small proportion of overall skin cancer surgeries.

To understand whether this benefit extends to more general skin cancer surgeries, investigators recruited patients from a high-volume skin cancer center in New Zealand who were treated from February to July 2019. In the double-blind, prospective PICASSo trial, patients were randomly assigned to receive an incision site injection of buffered local anesthetic alone (control group), buffered local anesthetic with microdoses of flucloxacillin (500 mcg/mL), or buffered local anesthetic with microdoses of clindamycin (500 mcg/mL). The most common surgery type was excision and direct closure (approximately 80% in all arms), and the mean volume injected per length of direct closure was 1.5 mL/cm.

The primary endpoint was the rate of postoperative SSIs, defined as a postoperative wound infection score of 5 or more. The SSI rate was calculated as the number of lesions with SSIs per total number of lesions in the group.

Overall, 681 patients with 1,133 total lesions were included in the study. Compared with the control arm, the rate of postoperative SSIs was nearly threefold lower among patients who received clindamycin, –2.1% (9 of 422) vs. 5.7% (22 of 388) in the control arm (P = .01 for clindamycin vs. control).

However, flucloxacillin did not demonstrate the same effectiveness. The flucloxacillin arm and the control arm demonstrated similar postoperative SSI rates – 5.3% (17 of 323) vs. 5.7%.

The results were similar after adjusting for baseline differences and lesion ulceration.

The researchers also found that the proportion of lesions that required postoperative systemic antibiotics was four times higher among the control arm, in comparison with the clindamycin arm (8% vs. 2.1%; P < .001). It was two times higher than in the flucloxacillin arm (8% vs. 4%; P = .03).

Treatment with microdoses of incisional flucloxacillin and clindamycin was safe and well tolerated.

The researchers speculated that clindamycin’s greater effectiveness may come down to its slightly broader coverage of commonly cultured bacteria in skin and soft tissue infections, including community-associated methicillin-resistant Staphylococcus aureus. Clindamycin is known to have more efficacy against anaerobic bacteria that may be lurking in chronically ulcerated skin lesions and is associated with less local tissue inflammation, compared with flucloxacillin.

Overall, “clindamycin was significantly more effective at preventing SSI than flucloxacillin in our study,” the authors conclude. They note that the use of clindamycin as a first-line prophylaxis agent against SSIs for patients undergoing skin cancer surgery is a practical option.

“These results establish evidence-based guidelines for antibiotic prophylaxis in one of the most common surgical interventions performed worldwide, where they have been previously absent,” the researchers say.

The authors of an editorial published with the study underscore other advantages of incisional microdosing with antibiotics.

“One advantage of cutaneous antibiotic administration is improved drug delivery to poorly perfused tissue, which would have limited reach by the systemic circulation,” wrote Amanda R. Sergesketter, MD, of Duke University, Durham, N.C., and Scott T. Hollenbeck, MD, of the University of Virginia, Charlottesville.

“While not evaluated in this study, local antibiotic delivery may be especially relevant to larger and more complex wounds,” the editorialists say. They note that the next step for future studies should be to evaluate prophylaxis in more complex situations.

“Such studies should be considered enthusiastically, given the clearly favorable impact on surgical site infections demonstrated in the PICASSo trial,” Dr. Sergesketter and Dr. Hollenbeck said.

The study was supported by a grant from the New Zealand Health Research Council. Dr. Hollenbeck reported educational grants to Duke University from Allergan, Acelity, Synovis, Integra, Smith & Nephew, Stryker, Cook, KLs Martin, Bard, VOptix, Scanlan, True Digital Surgery, Nautilus, Mitaka, Checkpoint Surgical, and Omniguide, and he is a founder and equity holder for InSoma Bio, a premarket company focused on tissue regeneration.

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.”

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.

MedscapeLIVE!

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.

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.

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.

To the Editor:

A 47-year-old man presented to the dermatology service with an asymptomatic plaque on the right thigh of 2 months’ duration. He had a medical history of HIV and Kaposi sarcoma as well as a recently relapsed primary effusion lymphoma (PEL) subsequent to an allogeneic bone marrow transplant. He initially was diagnosed with PEL 3 years prior to the current presentation during a workup for fever and weight loss. Imaging at the time demonstrated a bladder mass, which was biopsied and demonstrated PEL. Further imaging demonstrated both sinus and bone marrow involvement. Prior to dermatologic consultation, he had been treated with 6 cycles of etoposide, prednisolone, vincristine, cyclophosphamide, and doxorubicin (EPOCH); 6 cycles of brentuximab; 4 cycles of rituximab with gemcitabine and oxaliplatin; and 2 cycles of ifosfamide, carboplatin, and etoposide. Despite these therapies, he had 3 relapses, and oncology determined the need for a matched unrelated donor allogeneic stem cell transplant for his PEL.

At the time of dermatology consultation, the patient was being managed on daratumumab and bortezomib. Physical examination revealed an infiltrative plaque on the right inferomedial thigh measuring approximately 6.0 cm (largest dimension) with a small amount of peripheral scale (Figure 1). An ultrasound revealed notable subcutaneous tissue edema and increased vascularity without a discrete mass or fluid collection. A 4-mm punch biopsy demonstrated a dense infiltrate comprised of collections of histiocytes admixed with scattered plasma cells and mature lymphoid aggregates. Additionally, rare enlarged plasmablastic cells with scant basophilic cytoplasm and slightly irregular nuclear contours were visualized (Figure 2A). Immunohistochemistry was positive for CD3 with a normal CD4:CD8 ratio, CD68-highlighted histiocytes within the lymphoid aggregates, and human herpesvirus 8 (HHV-8)(or Kaposi sarcoma–associated herpesvirus) demonstrated stippled nuclear staining within the scattered large cells (Figure 2B). Epstein-Barr virus–encoded RNA staining was negative, though the area of interest was lost on deeper sectioning of the tissue block. The histopathologic findings were consistent with cutaneous extracavitary PEL. Shortly after this diagnosis, he died from disease complications.

Primary effusion lymphoma is an aggressive non-Hodgkin B-cell lymphoma that was first described by Knowles et al¹ in 1989. Primary effusion lymphoma occurs exclusively in the setting of HHV-8 infection and typically is associated with chronic immunosuppression related to HIV/AIDS. Cases that are negative for HIV-1 are rare but have been reported in organ transplant recipients and elderly men from areas with a high prevalence of HHV-8 infections. Most HIV-associated cases show concurrent Epstein-Barr virus infection, though the pathogenic meaning of this co-infection remains unclear.^2,3

Primary effusion lymphoma classically presents as an isolated effusion of malignant lymphoid cells within body cavities in the absence of solid tumor masses. The pleural, peritoneal, and pericardial spaces most commonly are involved. Extracavitary PEL, a rare variant, may present as a solid mass without effusion. In general, extracavitary tumors may occur in the setting of de novo malignancy or recurrent PEL.⁴ Cutaneous manifestations associated with extracavitary PEL are rare; 4 cases have been described in which skin lesions were the heralding sign of the disease.³ Interestingly, despite obligatory underlying HHV-8 infection, a review by Pielasinski et al³ noted only 2 patients with cutaneous PEL who had prior or concurrent Kaposi sarcoma. This heterogeneity in HHV-8–related phenotypes may be related to differences in microRNA expression, but further study is needed.⁵

The diagnosis of PEL relies on histologic, immunophenotypic, and molecular analysis of the affected tissue. The malignant cells typically are large with round to irregular nuclei. These cells may demonstrate a variety of appearances, including anaplastic, plasmablastic, and immunoblastic morphologies.^6,7 The immunophenotype displays CD45 positivity and markers of lymphocyte activation (CD30, CD38, CD71), while typical B-cell (CD19, CD20, CD79a) and T-cell (CD3, CD4, CD8) markers often are absent.^6-8 Human herpesvirus 8 detection by polymerase chain reaction testing of the peripheral blood or by immunohistochemistry staining of the affected tissue is required for diagnosis.^6,7 Epstein-Barr virus infection may be detected via in situ hybridization, though it is not required for diagnosis.

The overall prognosis for PEL is poor; Brimo et al⁶ reported a median survival of less than 6 months, and Guillet et al⁹ reported 5-year overall survival (OS) for PEL vs extracavitary PEL to be 43% vs 39%. Another review noted variation in survival contingent on the number of body cavities involved; patients with a single body cavity involved experienced a median OS of 18 months, whereas patients with multiple involved cavities experienced a median OS of 4 months,⁷ possibly due to the limited study of treatment regimens or disease aggressiveness. Even in cases of successful initial treatment, relapse within 6 to 8 months is common. Extracavitary PEL may have improved disease-free survival relative to classic PEL, though the data were less clear for OS.⁹ Limitations of the Guillet et al⁹ study included a small sample size, the impossibility to randomize to disease type, and loss of power on the log-rank test for OS in the setting of possible nonproportional hazards (crossing survival curves). Overall, prognostic differences between the groups may be challenging to ascertain until further data are obtained.

As with many HIV-associated neoplasms, antiretroviral treatment (ART) for HIV-positive patients affords a better prognosis when used in addition to therapy directed at malignancy.⁷ The general approach is for concurrent ART with systemic therapies such as rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone for the rare CD20⁺ cases, and cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) or dose-adjusted EPOCH therapy in the more common CD20⁻ PEL cases. Narkhede et al⁷ suggested avoidance of methotrexate in patients with effusions because of increased toxicity, but it is unclear if this recommendation is applicable in extracavitary PEL patients without an effusion. Additionally, second-line treatment modalities include radiation for solid PEL masses, HHV-8–targeted antivirals, and stem cell transplantation, though evidence is limited. Of note, there is a phase I-II trial (ClinicalTrials.gov identifier NCT02911142) ongoing for treatment-naïve PEL patients involving the experimental treatment DA-EPOCH-R plus lenalidomide, but the trial is ongoing.¹⁰

We report a case of cutaneous PEL in a patient with a history of Kaposi sarcoma. The patient’s deterioration and ultimate death despite initial treatment with EPOCH and bone marrow transplantation followed by final management with daratumumab and bortezomib confirm other reports that PEL has a poor prognosis and that optimal treatments are not well delineated for these patients. In general, the current approach is to utilize ART for HIV-positive patients and to then implement chemotherapy such as CHOP. Without continued research and careful planning of treatments, data will remain limited on how best to serve patients with PEL.

Inflammation produces a firm painful nodule that often forms a central crust and enlarges rapidly, mimicking cutaneous malignancy. Chondrodermatitis nodularis helicis is believed to be caused by chronic pressure on the pinna, usually from sleeping, which causes compromised blood supply. However, there is a wide range of additional risk factors,¹ including trauma (eg, pressure), environmental insult (eg, sun or cold exposure), and autoimmune processes (eg, systemic lupus erythematosus, scleroderma). Chondrodermatitis nodularis helicis after Mohs micrographic surgery (MMS) is rare. We report a novel case of CNH as a postoperative complication of MMS following adjuvant radiation therapy.

A 61-year-old man presented to the MMS clinic for treatment of a primary squamous cell carcinoma of the right posterior helix. Stage I MMS demonstrated tumor invasion in the deep dermis directly overlying the auricular cartilage, as well as large-nerve (ie, >0.1 mm) perineural invasion. Two additional stages were taken; negative margins were obtained on Stage III. The defect was repaired by primary closure (Figure 1). Considering the presence of perineural invasion around a large nerve, the patient elected to receive adjuvant radiation therapy consisting of 50 Gy in 20 fractions administered to the right ear over 1 month.

Two months after completion of adjuvant radiation therapy, the patient returned to the clinic with a tender pink papule on the right crus within the radiation portal but nonadjacent to the surgical scar (Figure 2). Histopathology from a tangential biopsy revealed acanthosis, dermal sclerosis, and degenerated cartilage, consistent with CNH. Stellate fibroblasts also were seen, suggesting changes related to prior radiation therapy (Figure 3).

Although CNH is a benign condition, it can be concerning in the context of patient follow-up after MMS given its clinical appearance, which is similar to nonmelanoma skin cancer. The differential diagnosis of CNH includes hypertrophic actinic keratosis, basal cell carcinoma, and squamous cell carcinoma. The diagnosis is based on clinical history and confirmed by histopathologic examination.

Chondrodermatitis nodularis helicis in close proximity to a prior MMS site should lower the threshold for biopsy because the area is already known to be affected by actinic damage and cutaneous carcinogenesis. The histopathology of CNH often is characterized by epidermal acanthosis with ulceration, perichondral fibrosis, and a variable degree of cartilage degeneration associated with granulation tissue.²

The scarce subcutaneous tissue and limited blood supply of the pinna offer minimal cushioning and poor circulation to underlying cartilage. These anatomic features predispose the pinna to inflammation and ischemia.¹ Mohs micrographic surgery may inadvertently cause damage to surrounding tissue because of excision of cartilage, mechanical manipulation, severance of the extant blood supply, electrocautery, fenestration in preparation for skin grafting, compression from a wound dressing, and other factors related to surgery. In addition, following MMS, scar tissue and swelling with compression of adjacent structures can further inhibit circulation and lead to CNH.

In our case, multiple factors may have contributed to CNH after MMS, including postoperative swelling and compression, prior actinic damage, and other environmental factors. Given that CNH occurred within the radiation portal, we postulated that adjuvant radiation may have played a role in the pathogenesis of the patient’s CNH. Pandya et al³ reported CNH after radiation therapy for a brain tumor.

One prior study showed that CNH treated by surgical excision recurred in 34% of patients.⁴ In all of these patients, the CNH was completely excised; however, trauma from the surgical procedure itself likely resulted in recurrence of CNH. Darragh et al⁵ reported a case of CNH after MMS on the right nasal vestibule following wound reconstruction that utilized a cartilage graft from the right ear.

Our patient demonstrated an unusual but concerning complication associated with MMS. The location of CNH also was not in a traditional location but rather near the superior helical crus. Although CNH is benign by nature, it can mimic recurrence of a tumor when it presents close to the site of prior MMS. Diagnostic biopsy of CNH should be considered to rule out recurrence of skin cancer.

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 – 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.

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

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.

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

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.

SEATTLE – The use of Mohs surgery may improve survival for patients with early-stage Merkel cell carcinoma (MCC), results from a large, retrospective study show.

Compared with conventional wide local excision, survival was significantly improved among patients treated with Mohs, and a subgroup analysis showed that the survival benefit remained for patients with risk factors.

“At 10 years, overall survival was about 21% higher for those treated with Mohs surgery versus those treated with conventional surgery,” said lead author Shayan Cheraghlou, MD, a dermatology resident at the New York University School of Medicine. “On multivariable analysis, which controlled for tumor and patient factors, Mohs was associated with an over 40% reduction in the hazard for death.”

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

MCC is a rare, aggressive, neuroendocrine cutaneous malignancy that carries a high mortality rate. The estimated 5-year survival for patients with localized disease is about 50%, Dr. Cheraghlou noted. “That extrapolates to about 55% for T1 tumors and down to about 30% for T4 tumors.”

Although it’s considered to be a rare cancer, the incidence of MCC has been rapidly rising, and in fact it doubled during the period from the 1990s to the 2010s.

Most commonly treated with wide local excision with or without adjuvant radiation therapy, Mohs as monotherapy may offer an alternative treatment option for patients with MCC. It is generally accepted that the optimal treatment for tumors without regional lymph node involvement is surgical, but the data regarding the optimal surgical approach are mixed. Current National Comprehensive Cancer Network guidelines state that either Mohs surgery or wide local excision can be used.

“However, these guidelines do not indicate a preference for one modality over the other,” said Dr. Cheraghlou, “and present them as interchangeable treatment options.”

A growing body of literature supports Mohs surgery for many types of rare tumors, including MCC. For example, as previously reported at the 2021 ACMS meeting, one study found that Mohs surgery compared favorably with the standard treatment approach when it came to recurrence rates for patients with MCC. The 5-year disease-specific survival rate was 91.2% for patients with stage I disease and 68.6% for patients with stage IIa. These rates were comparable with rates for historical control patients who were treated with wide local excision, with or without radiation (81%-87% for stage I disease, and 63%-67% for stage II).

Study details

In the current study, Dr. Cheraghlou and colleagues sought to evaluate the association of the type of surgical approach with patient survival after excision of early-stage MCC. They conducted a retrospective cohort study using the National Cancer Database to identify cases of MCC with T1/T2 tumors. A total of 2,313 patients who were diagnosed from 2004 to 2018 with pathologically confirmed negative lymph node involvement and who were treated with Mohs surgery or wide lesion excision were included in the analysis.

“About 90% were T1 tumors, about 40% were located on the head and neck, and the vast majority – about 60% – were treated with wide local excision,” he explained. “Only about 5% received Mohs surgery for treatment of the primary tumor.”

But when the researchers assessed survival outcomes, they found that treatment with Mohs surgery was associated with significantly improved overall survival.

The unadjusted 3-, 5-, and 10-year survival rates for patients treated with Mohs was 87.4% (SE: 3.4%), 84.5% (SE: 3.9%), and 81.8% (SE: 4.6%), respectively, while for wide lesion excision, the rates were 86.1% (SE: 0.9%), 76.9% (SE: 1.2%), and 60.9% (SE: 2.0%), respectively.

For patients who underwent treatment with narrow margin excision, survival rates were similar as for those treated with wide lesion excision, with 3-, 5-, and 10-year survival rates of 84.8% (SE: 1.4%), 78.3% (SE: 1.7%), and 60.8% (SE: 3.6%), respectively.

On multivariable survival analysis, Mohs surgery was associated with significantly improved survival, compared with wide lesion excision (hazard ratio, 0.594; P = .038). This was also true after multivariable analysis for patients who had one or more NCCN risk factors, for whom improved survival was also seen with Mohs (HR, 0.530; P = .026).

The results did not differ after a sensitivity analysis that included T3 and T4 tumors.

Given that the use of Mohs was so infrequent, compared with standard surgery, the researchers investigated the factors that were associated with the use of Mohs. High-volume MCC centers were significantly more likely to utilize Mohs than wide lesion excision (odds ratio, 1.993; P < .001), compared with other facilities.

“This study has important implications going forward,” Dr. Cheraghlou concluded. “We think it’s important how few patients were treated with Mohs for Merkel cell, and it was slightly more likely to happen in a high-volume center.”

The reasoning for that may be that high-volume centers are more likely to have a surgeon trained to perform Mohs surgery for MCC. “Or perhaps they are more attuned to the benefits of this procedure,” he said. “We can’t tell that from our data, but its notable that it’s such a small proportion of patients – especially when we consider that it is associated with improved survival for the patients who receive it.”

He added that efforts to increase the utilization of Mohs may yield improved local control and overall survival for these patients. “And perhaps with more data, future versions of guidelines may indicate a preference for Mohs over conventional incisions.”
 

No changes to current practice

Asked to comment on the study, Anthony J. Olszanski, RPh, MD, associate professor, department of hematology/oncology, Fox Chase Cancer Center, Philadelphia, noted that while the results are intriguing, they must be interpreted with caution.

“This study was retrospective in nature, and unrecognized biases can influence results,” he said. “Additionally, given the relative rarity of Merkel cell carcinoma, the sample size is expectantly small.”

But importantly, Dr. Olszanski emphasized, Mohs may more often have been recommended for patients with lesions that appear less aggressive. “Many patients undergoing wide lesion excision may have been referred by Mohs surgeons secondary to features or characteristics of lesions which were worrisome,” he explained. “The results of this study do not opine on why Mohs would impact overall survival over wide lesion excision, a point worthy of consideration. Presently, both modalities can be considered for patients with T1/T2 MCC. The results of this study should not change current practice and would lend themselves to a more robust study.”

No external funding of the study was reported. Dr. Cheraghlou has disclosed no relevant financial relationships. Dr. Olszanski has received financial support from Merck and BMS for participated on advisory boards.

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.

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.

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.

When asked about her approach to supporting patients in the long term, Dr. Hauser said that she recommends sequential, gradual changes. Dr. Hauser added that she suggests her patients prioritize implementing dietary changes that they are confident they can maintain.

Dr. Hauser and Dr. Bittleman report no relevant financial relationships.
