Among people diagnosed with cutaneous melanoma in the United States, those who live in rural areas have significantly lower rates of survival than those who live in urban areas, results from an analysis of data from the National Cancer Institute showed.

“Melanoma is currently the fifth most common malignancy in the United States, with approximately 106,000 new cases and 7180 reported deaths occurring in 2021,” the study’s first author, Mitchell Taylor, MD, a dermatology research fellow at the University of Nebraska, Omaha, and colleagues wrote in the abstract, which was presented during a poster session at the annual meeting of the Society for Investigative Dermatology. “Rural areas have been shown to bear a higher melanoma disease burden, yet there is a paucity of national-level studies examining these disparities.”

To characterize the rural population diagnosed with cutaneous melanoma and assess associated disparities in the United States, the researchers queried the NCI’s Surveillance, Epidemiology, and End Results database to identify individuals diagnosed with cutaneous melanoma from 2000 to 2020 (International Classification of Diseases, 3rd Edition, 8720/3 — 8780/3; Primary Site codes C44.0-C44.9). They drew from US Office of Management and Budget terminology to define and categorize rural and urban communities.

Among 391,047 patients included during the study period, binary logistic regression analysis revealed that patients in rural areas had a greater odds of being older, from ages 50 to 75 years (odds ratio [OR], 1.10; P < .001); had annual incomes < $70,000 (OR, 16.80; P < .001); had tumors located on the head and neck (OR, 1.24; P < .001); and presented with regional/distant disease (OR, 1.13; P < .001).



As for disease-specific survival, patients living in rural areas had significantly reduced survival compared with those living in urban areas (a mean of 207.3 vs 216.3 months, respectively; P < .001). Multivariate Cox regression revealed that living in a rural setting was significantly associated with reduced disease-specific survival (hazard ratio [HR], 1.10; P < .001), as was having head and neck tumors (HR, 1.41; P < .001).“Overall, this study underscores a significant decrease in disease-specific survival among rural patients diagnosed with cutaneous melanoma and establishes a significant association between rural living and high-risk primary tumor locations, particularly the head and neck,” the authors concluded.

Lucinda Kohn, MD, assistant professor of dermatology in the Centers for American Indian and Alaska Native Health at the University of Colorado at Denver, Aurora, Colorado, who was asked to comment on the results, said the findings echo the results of a recent study which characterized melanoma rates among non-Hispanic American Indian/Alaska Native individuals from 1999 to 2019.

“I suspect this decreased disease-specific survival highlights the issues our rural-residing patients face with access to dermatology care,” Dr. Kohn told this news organization. “Dermatologists are able to detect thinner melanomas than patients [and] are preferentially concentrated in metropolitan areas. Dermatologists are also the most skilled and knowledgeable to screen, diagnose, and manage melanomas. Having fewer dermatologists in rural areas impedes melanoma care for our rural-residing patients.”

Neither the researchers nor Dr. Kohn reported any relevant disclosures.

Features of Merkel Cell in Hispanic Patients Explored

Article Type

Wed, 06/12/2024 - 11:05

Compared with White patients with Merkel cell carcinoma (MCC), non-White Hispanic patients more commonly presented younger than 70 years of age and were more often female. In addition, the most affected site was the upper limb/shoulder, which differs from what has been reported in previous studies.

Those are key findings from a retrospective study of national cancer data that was presented during a poster session at the annual meeting of the Society for Investigative Dermatology.

“Merkel cell carcinoma is an infrequent and aggressive form of neuroendocrine skin cancer that mainly impacts individuals of White ethnicity, with a general occurrence rate of 0.7 instances per 100,000 person-years,” one of the study authors, Luis J. Borda, MD, chief dermatology resident at Eastern Virginia Medical School, Norfolk, Virginia, told this news organization. The incidence of MCC is increasing among all racial groups, especially in the Hispanic population, he added.

To determine how age, sex, and primary site of MCC differ in White vs non-White Hispanic patients, the researchers evaluated the 22 population-based cancer registries of the National Cancer Institute’s Surveillance, Epidemiology, and End Results (SEER) Program from 2000 through 2020. They reported categorical variables as counts and percentages and used chi-square test with Yates’s correction to assess the association between categorical variables.

Of the 17,920 MCCs identified by the researchers, 40 (0.22%) were in non-White Hispanic patients. Compared with the White patients with MCC, significantly fewer non-White Hispanic patients were age 70 years or older (50% vs 72.1%, respectively; P < .001), and MCC was more common in female non-White Hispanic patients (23, or 57.5%), while White patients with MCC were predominantly male (11,309, or 63.2%; P < .05). “This suggests that MCC in non-White Hispanic patients may involve different risk factors related to age beyond just cumulative UV exposure and aging-related immunosenescence, which may additionally account for the higher prevalence of females in this cohort, as historically male outdoor occupation has resulted in increased lifetime cumulative UV exposure,” Dr. Borda said.



The head and neck were the most common sites of disease involvement in White patients (41.9% vs 27.5% in non-White Hispanic patients; P = .09), while the upper limb and shoulder were the most common sites of disease involvement in non-White Hispanic patients (37.5% vs 23.8% in White patients; P = .06). This finding “differs from previous studies showing head/neck being the most common site in Hispanics,” Dr. Borda said, adding that this could be a result of White patients not being included in the Hispanic cohort in this study. “Because non-White Hispanic patients have darker skin, they may have proportionally more cases on sun-protected skin, as is described by the present data, suggesting that they are less likely to have UV-driven MCC.”

The study “highlights distinct demographic and clinical characteristics of MCC among non-White Hispanic patients compared to their White counterparts, emphasizing the importance of considering race/ethnicity in understanding the epidemiology of this rare but increasingly prevalent cancer,” Dr. Borda said. He and his co-authors are planning to do further research on the increasing incidence of MCC in non-White Hispanic patients and on staging at diagnosis compared to White patients.

Dr. Borda acknowledged certain limitations of the analysis, including the small sample size in the non-White Hispanic group, the retrospective nature of SEER data, selection bias, and the potential for underreporting. He and his co-authors reported having no financial disclosures.

Study Finds Mace Risk Remains High in Patients with Psoriasis, Dyslipidemia

Tue, 06/04/2024 - 16:46

Over a period of 5 years, the likelihood of major adverse cardiovascular events (MACE) in patients with psoriasis and dyslipidemia who were on statin therapy was 40% greater than that in non-psoriasis patients with dyslipidemia on statin therapy, even after adjusting for covariates, results from a large retrospective study showed.

“It is well-established that psoriasis is an independent risk factor for the development of MACE, with cardiometabolic risk factors being more prevalent and incident among patients with psoriasis,” the study’s first author Ana Ormaza Vera, MD, a dermatology research fellow at Eastern Virginia Medical School, Norfolk, said in an interview after the annual meeting of the Society for Investigational Dermatology, where the study was presented during a late-breaking abstract session.

Current guidelines from the joint American Academy of Dermatology/National Psoriasis Foundation and the American Academy of Cardiology/American Heart Association Task Force recommend statins, a lipid-lowering and anti-inflammatory therapy, “for patients with psoriasis who have additional risk-enhancing factors, similar to recommendations made for the general population without psoriasis,” she noted. But how the incidence of MACE differs between patients with and without psoriasis while on statin therapy “has not been explored in real-world settings,” she added.

To address this question, the researchers used real-world data from the TriNetX health research network to identify individuals aged 18-90 years with a diagnosis of both psoriasis and lipid disorders who were undergoing treatment with statins. Those with a prior history of MACE were excluded from the analysis. Patients with lipid disorders on statin therapy, but without psoriatic disease, were matched 1:1 by age, sex, race, ethnicity, common risk factors for MACE, and medications shown to reduce MACE risk. The researchers then assessed the cohorts 5 years following their first statin prescription and used the TriNetX analytics tool to calculate the odds ratio (OR) with 95% CI to evaluate the likelihood of MACE in the presence of statin therapy.

Dr. Ormaza Vera and colleagues identified 20,660 patients with psoriasis and 2,768,429 patients without psoriasis who met the criteria for analysis. After propensity score matching, each cohort included 20,660 patients with a mean age of 60 years. During the 5-year observation period, 2725 patients in the psoriasis cohort experienced MACE compared with 2203 patients in the non-psoriasis cohort (OR, 1.40; 95% CI, 1.317-1.488).



“This was an unexpected outcome that challenges the current understanding and highlights the need for further research into tailored treatments for cardiovascular risk in psoriasis patients,” Dr. Ormaza Vera told this news organization.

She acknowledged certain limitations of the study, including its retrospective design, the inherent limitations of an observational study, and the use of electronic medical record data.

Lawrence J. Green, MD, clinical professor of dermatology, George Washington University, Washington, who was asked to comment on the study results, said that the findings imply that there is more than statin use alone to protect someone with psoriasis from having an increased risk for MACE. “This is not really surprising because statin use alone is only part of a prevention strategy in someone with psoriasis who usually has multiple comorbidities,” Dr. Green said. “On the other hand, the study only went out for 5 years and cardiovascular disease is a long accumulating process, so it could also be too early to demonstrate MACE prevention.”

The study was funded by a grant from the American Skin Association. Dr. Ormaza Vera and her coauthors reported having no relevant disclosures. Dr. Green disclosed that he is a speaker, consultant, or investigator for many pharmaceutical companies.

Dupilumab Evaluated as Treatment for Pediatric Alopecia Areata

Children with concomitant atopic dermatitis (AD) and alopecia areata (AA) who were treated with dupilumab demonstrated significant hair regrowth over a mean of nearly 68 weeks, preliminary results from a small case series showed.

“We might be opening a new avenue for a safe, long-term treatment for our children with AA,” the study’s lead investigator, Emma Guttman-Yassky, MD, PhD, professor and chair of dermatology at the Icahn School of Medicine at Mount Sinai, New York City, said in an interview during the annual meeting of the Society for Investigative Dermatology (SID), where the results were presented during a poster session. “I think AA is likely joining the atopic march, which may allow us to adapt some treatments from the atopy world to AA.”

When the original phase 2 and phase 3 trials of dupilumab for patients with moderate to severe AD were being conducted, Dr. Guttman-Yassky, one of the investigators, recalled observing that some patients who also had patch alopecia experienced hair regrowth. “I was scratching my head because, at the time, AA was considered to be only a Th1-driven disease,” she said. “I asked myself, ‘How can this happen?’ I looked in the literature and found many publications linking atopy in general to alopecia areata. The largest of the dermatologic publications showed that eczema and atopy in general are the highest comorbidities in alopecia areata.”

“This and other findings such as IL [interleukin]-13 genetic linkage with AA and high IgE in patients with AA link AA with Th2 immune skewing, particularly in the setting of atopy,” she continued. In addition, she said, in a large biomarker study involving the scalp and blood of patients with AA, “we found increases in Th2 biomarkers that were associated with alopecia severity.”
 

Case Series of 20 Pediatric Patients

As part of a case series of children with both AD and AA, Dr. Guttman-Yassky and colleagues evaluated hair regrowth using the Severity of Alopecia Tool (SALT) in 20 pediatric patients (mean age, 10.8 years) who were being treated at Mount Sinai. They collected patient demographics, atopic history, immunoglobulin E (IgE) levels, and SALT scores at follow-up visits every 12-16 weeks for more than 72 weeks and performed Spearman correlations between clinical scores, demographics, and IgE levels.

At baseline, the mean SALT score was 54.4, the mean IgE level was 1567.7 IU/mL, and 75% of patients also had a family history of atopy. The mean follow-up was 67.6 weeks. The researchers observed a significant reduction in SALT scores at week 48 compared with baseline (a mean score of 20.4; P < .01) and continued improvement up to at least 72 weeks (P < .01 vs baseline). They also noted that patients who achieved a treatment response at week 24 had baseline IgE levels > 200 IU/mL.

In other findings, baseline IgE positively correlated with improvement in SALT scores at week 36 (P < .05), while baseline SALT scores positively correlated with disease duration (P < .01) and negatively correlated with improvement in SALT scores at weeks 24, 36, and 48 (P < .005). “The robustness of the response surprised me,” Dr. Guttman-Yassky said in the interview. “Dupilumab for AA takes time to work, but once it kicks in, it kicks in. It takes anywhere from 6 to 12 months to see hair regrowth.”



She acknowledged certain limitations of the analysis, including its small sample size and the fact that it was not a standardized trial. “But, based on our data and the adult data, we are very encouraged about the potential of using dupilumab for children with AA,” she said.

Mount Sinai recently announced that the National Institutes of Health awarded a $6.6 million, 5-year grant to Dr. Guttman-Yassky to further investigate dupilumab as a treatment for children with AA. She will lead a multicenter controlled trial of 76 children with alopecia affecting at least 30% of the scalp, who will be randomized 2:1 (dupilumab:placebo) for 48 weeks, followed by 48 weeks of open-label dupilumab for all participants, with 16 weeks of follow-up, for a total of 112 weeks. Participating sites include Mount Sinai, Yale University, Northwestern University, and the University of California, Irvine.

Dr. Guttman-Yassky disclosed that she is a consultant to many pharmaceutical companies, including dupilumab manufacturers Sanofi and Regeneron.

Analysis Finds Minority of Chronic Wounds Treated by Dermatologists

Article Type

Mon, 06/03/2024 - 15:14

Between 2011 and 2019, chronic cutaneous wounds accounted for about one third of all health care visits for cutaneous wounds, and the most common diagnoses were open wounds of the thumb without nail damage. However, fewer than 8% of chronic wounds were managed by dermatologists during this time.

Those are among key findings from an analysis of National Ambulatory Medical Care Survey (NAMCS) data between 2011 and 2019 presented as a late-breaking abstract at the annual meeting of the Society for Investigative Dermatology. “Cutaneous wounds were estimated to account for 28.1 to 96.1 billion dollars in US health care costs in 2014,” one of the study authors, Rithi Chandy, MD, MS, a research fellow at the Center for Dermatology Research at Wake Forest University School of Medicine, Winston-Salem, North Carolina, said in an interview following the meeting. “By examining national trends in patient visits and treatment, we may be able to better inform health care utilization for cutaneous wounds.”

Dr. Rithi Chandy


Dr. Chandy and colleagues analyzed de-identified patient data from the 2011 to 2019 NAMCS for acute and chronic wound diagnoses, medications prescribed, and physician specialty categories. During the time studied, 5.76 billion patient visits were made, including 45.1 million visits for cutaneous wounds. Of these, the most common diagnoses were open wounds of the thumb without nail damage (7.96%), the lower leg (5.75%), nonpressure chronic ulcers of other parts of the foot (5.08%), and open wounds of the ear (5%).

Among all visits for cutaneous wounds, about one third were chronic cutaneous wounds, with the following descriptions: “Nonpressure chronic ulcer of other part of foot” (17.8%); “nonpressure chronic ulcer of skin, not elsewhere classified” (9.38%); and “ulcer of lower limbs, excluding decubitus, unspecified” (8.72%). “The frequency of patient visits per year during the study period remained stable for both acute and chronic wounds,” Dr. Chandy said. The number of visits for which antimicrobials were used was stable over time for both acute and chronic cutaneous wounds, with the exception of increased use of antivirals for chronic cutaneous wounds, he added.

Specifically, prescriptions were issued in 156 million visits over the time studied, most commonly cephalexin (4.22%), topical silver sulfadiazine (1.59%), topical mupirocin (1.12%), and miscellaneous antibiotics (1.18%).

“Our data shows that topical mupirocin is the most commonly used topical antimicrobial for cutaneous wounds,” Dr. Chandy said. “However, there are reports of emerging bacterial resistance to mupirocin. Our data can inform ongoing efforts to promote antimicrobial stewardship and drug development to provide alternative options that are less likely to induce antimicrobial resistance.”

In findings limited to specialty-specific NAMCS data available from 2011 and from 2013 to 2016, dermatologists managed 3.85% of overall cutaneous wounds, 2.35% of acute wounds, and 7.39% of chronic wounds. By contrast, Dr. Chandy said, 21.1% of chronic wounds were managed by general/family practice physicians, 20.7% by internists, 6.84% by general surgeons, and 5.65% by orthopedic surgeons.

“As dermatologists are experts in the structure and function of the skin and are trained to manage cutaneous disorders including wound healing, we [believe that] dermatologists are equipped with the skill set” for managing wounds, especially for chronic ulcers, he said. The decline in dermatologists who specialize in wound care, he added, “underscores the need for structured dermatology fellowship programs to prepare next-generation dermatologists to address this shortage and ensure dermatology leadership in cutaneous wound healing.”

Dr. Chandy acknowledged certain limitations of the study, including the potential for misclassification of diagnoses or medications prescribed and the fact that the NAMCS database is unable to provide insight into individual patient experiences such as continual cutaneous wound management for the same patient over time.

In the opinion of Shari R. Lipner, MD, PhD, associate professor of clinical dermatology and director of the Nail Division at Weill Cornell Medicine, New York, who was asked to comment on the study, the most interesting finding was that dermatologists cared for a small minority of patients with cutaneous wounds. “It would be interesting to know whether this is due to dermatologist shortages or knowledge gaps on the part of primary care physicians or patients that dermatologists are trained to care for wounds,” Dr. Lipner told this news organization. Other unanswered questions, she noted, “are patient demographics, geographic locations, and comorbidities.”

One of the study authors, Steven R. Feldman, MD, PhD, professor of dermatology at Wake Forest University, disclosed that he has received research, speaking and/or consulting support from numerous pharmaceutical companies. No other authors reported having relevant disclosures. Dr. Lipner reported having no disclosures.
