Treating High Stage cSCC: Better Results With Mohs Surgery vs Wide Local Excision, Study Finds
PHOENIX — . The benefit was seen across all outcome measures, including rates of recurrence, metastasis, and mortality.
These data support Mohs surgery as being the preferred surgical treatment option for high-stage cSCC, commented lead author David M. Wang, MD, Mohs Micrographic Surgery and Dermatologic Oncology Fellow, at Harvard’s Brigham and Women’s Hospital (BWH)/Dana-Farber Cancer Institute, Boston. “We found that across all outcomes, high-stage cSCC treated with WLE had a roughly twofold greater risk for recurrence, metastasis, or disease-specific death compared to Mohs,” he said at the annual meeting of the American College of Mohs Surgery (ACMS), where he presented the results.
External validation using data from a multicenter cSCC research collaboration from 12 contributing sites from across the United States, as well as international sites, was also conducted. “We performed the external validation by comparing results of the BWH-only cohort, which was the primary study, with the full multicenter data and with the full multicenter data minus the BWH cohort, and the findings were nearly identical in all three analyses,” Dr. Wang said.
Although patients diagnosed with cSCC usually have good outcomes, high-stage disease is associated with a higher risk for recurrence, metastasis, and death. Both Mohs surgery and WLE are used to treat cSCC, but a comparison of outcomes has not been well established in the setting of high-stage cSCC. Comparing the two surgical strategies can be problematic, as both patient and/or tumor characteristics can make it difficult to determine which outcomes can be attributed solely to the treatment type.
Mohs Superior Across the Board
In the retrospective cohort study, Dr. Wang and colleagues aimed to compare the results of Mohs surgery and WLE in patients with high-stage cSCC (BWH Staging System T2b or T3) and used statistical methods to balance baseline patient and tumor characteristics.
“To control for confounding by indication — differences in baseline patient or tumor characteristics — that are associated with both the treatment received and outcomes, we used propensity score weighting so that the baseline characteristics were balanced in the two treatment groups,” Dr. Wang told this news organization. “This statistical method aims to simulate randomization in a randomized controlled trial such that any differences in outcomes after propensity score weighting is attributed solely to the treatment received.”
The study used electronic medical records from a single tertiary care academic institution, and 216 patients with high-stage cSCC who had undergone surgery from January 2000 to December 2019 were included in the analysis. The median follow-up time was 33.1 months.
They found that overall, the risk for all adverse outcomes was lower among patients who had undergone Mohs surgery than among those treated with WLE, with the following results: Rates of local recurrence (5-year CI, 10.8% vs 22.1%, respectively; P = .003), nodal metastasis (11.9% vs 19.3%; P = .04), distant metastasis (4.7% vs 9.0%; P = .09), any recurrence (17.0% vs 34.2%; P < .001), and disease-specific death (8.5% vs 20.3%; P = .001).
“The data supports Mohs surgery as the preferred surgical treatment option for high-stage cSCC in accordance with NCCN [National Comprehensive Cancer Network] guidelines for very high-risk cSCC,” Dr. Wang said. He pointed out that the terminology “very high risk” in NCCN equates to “high stage” in other staging systems (BWH T2b or higher, AJCC T3 or higher).
There is still “a substantial proportion” of patients with high-stage cSCC who are eligible for Mohs but are treated with WLE, he added. “Our hope is that these findings provide additional data to support Mohs as the standard of care for primary surgical treatment of high-stage cSCC.”
Supports Benefits of Mohs
Weighing in on the research, Thomas E. Rohrer, MD, a dermatologic surgeon in Chestnut Hill, Massachusetts, noted that this was an excellent study that demonstrates benefits of Mohs surgery over straight excision on essentially all outcomes investigated and measured.
“The data clearly shows that Mohs should be used whenever possible,” he said. “There are some patients and facilities that do not have access or timely access to Mohs, so they would likely proceed with standard wide local excision. Otherwise, if there is the capability to perform Mohs, it would be preferred,” he added.
“There is no benefit to a standard excision over Mohs,” Dr. Rohrer emphasized. “If a surgeon is not sure if they have attained clear margins, they could and often do take a little more tissue to be certain.”
Also asked to comment on the data, Chad L. Prather, MD, a dermatologist in Baton Rouge, Louisiana, said, “We know that Mohs has been used for cancers that are not highly staged and we know it’s better than WLE, but this study shows that it is beneficial for higher stage cancers.”
However, he cautioned that unlike early-stage cancers, where Mohs is usually a definitive treatment, with higher stage disease it is a starting point. “As a takeaway, Mohs is superior, but it needs to be followed through,” he said. “These patients need to be closely followed as they are at a high risk for recurrence and metastasis and may need to be worked up for lymph node involvement and need additional therapy going forward.”
Dr. Prather also pointed out that there are circumstances when WLE may be a more suitable treatment. “Mohs is not very good if there is bony involvement,” he said. “This most often happens when the lesion is on the scalp and has invaded the skull. WLE may still be the preferred choice.”
Additionally, Mohs is not the best choice if the tumor is broken into multiple segments. “In these cases, WLE may be preferred,” Dr. Prather added. “But overall, Mohs is one of the best tools we have, and it stands to reason that it works well for high-risk tumors, as this study shows.”
The study was independently supported. Dr. Wang reported no relevant financial relationships. Dr. Rohrer and Dr. Prather had no relevant disclosures.

FROM ACMS 2024
Study Finds Immunosuppression Affects Risk for Poor Outcomes in Patients with cSCC
PHOENIX — Immunosuppression is an independent risk factor for poorer outcomes in patients with cutaneous squamous cell carcinoma (cSCC), according to new research that was presented at the American College of Mohs Surgery (ACMS) 2024 annual meeting.
Even though immunosuppression is strongly associated with an increased risk for cSCC, studies to date have generally not shown it to be an independent risk factor for metastasis and disease-specific death (DSD), after accounting for primary tumor stage.
“Solid organ transplant puts patients at risk for developing cutaneous squamous cell carcinoma, and it’s more likely to have aggressive features,” said study author Jason Klein, MD, PhD, a dermatology resident at University of Texas Southwestern Medical Center, Dallas. “But it’s still not known if immunosuppression is an independent risk factor.”
Other groups “have tried to tackle this, but they have all primarily been single-institution data,” he noted, adding that “results so far have been tipping the scale towards immunosuppression not being an independent risk factor” for worse outcomes.
Immunosuppressed individuals face a greater risk for cSCC than the general population and often present with more aggressive, multifocal disease. However, Dr. Klein explained that a previous retrospective study comprising a cohort of approximately 7600 tumors from two centers reported that immunosuppression was not an independent risk factor for both tumor metastasis and cancer-specific death after adjusting for tumor characteristics.
Tipped the Scale
Therefore, the goal of the current study was to repeat this analysis but in a much larger retrospective cohort. Dr. Klein and his colleagues pooled cSCC data from 12 dermatology centers (11 academic and one private) that were located in the United States, Spain, and Brazil. The cohort included 4392 patients (3769 immunocompetent patients and 623 immunosuppressed patients) with 19,237 tumors (15,191 immunocompetent and 4046 immunosuppressed). Study endpoints included local recurrence, metastasis (nodal, satellite/in-transit, and distant), DSD, and “major poor outcomes” (defined as metastasis and DSD combined).
About 30% of the immunosuppressed patients were organ transplant recipients (OTR) and 10% had chronic lymphocytic leukemia (CLL). Half of the immunocompetent patients (50.3%) underwent Mohs surgery as the primary treatment, as did 58.2% of the immunosuppressed patients.
On multivariable analysis, significant predictors of “major poor outcomes” included immunosuppression (subdistribution hazard ratio [SHR], 1.3; P = .04), Brigham and Women’s Hospital tumor stage (SHR 6.7 for T2a, 18.1 for T2b, and 37.2 for T3; P < .001 for all), location on the head/neck (SHR, 2.1; P < .001), and adjuvant radiation (SHR, 1.6; P < .001).
But when metastasis and DSD were evaluated separately, immunosuppression was only predictive of DSD (SHR, 1.7; P = .008) but not metastasis (SHR, 1.2; P = .21). Dr. Klein explained that they also conducted a separate subanalysis limited to OTR and patients with CLL, which demonstrated that immunosuppression was no longer a significant predictor of “major poor outcomes” (SHR, 0.9; P = .66 for OTR; SHR, 1.4; P = .25 for CLL).
“Organ transplant status and CLL were not independent risk factors for major poor outcomes,” he said. “But in summary, we may be tipping the scale to immunosuppression being a risk factor.”
Asked to comment on the findings, Naissan O. Wesley, MD, director of Mohs surgery, Skin Care and Laser Physicians of Beverly Hills, Los Angeles, California, stated that “this larger scale study presented at this meeting was important to further confirm what we see in everyday practice, that immunosuppression may lead to poorer outcomes in patients with cutaneous squamous cell carcinoma.”
Also weighing in on the data, Jesse M. Lewin, MD, chief of Mohs micrographic and dermatologic surgery, at the Icahn School of Medicine at Mount Sinai, New York City, noted that the treatment of cSCC in high-risk patients has been challenging because of the historical lack of data and large studies to guide management.
“The authors provide a large cohort to help stratify which patients are most at risk for poor outcomes, which can inform our decision to refer for neoadjuvant or adjuvant treatment and multi-disciplinary management,” he said. “This is the first step in being able to optimize cure in these patients.”
The study was independently supported. Dr. Klein, Dr. Lewin, and Dr. Wesley reported no relevant financial relationships.

FROM ACMS 2024
Study Finds Injuries, Stress Levels Increased Among Mohs Surgeons
PHOENIX — In addition, most surgeons did not feel prepared to manage or prevent these symptoms.
“Our study highlights the need to implement ergonomic training and emotion-focused coping skills, as part of fellowship training and the continuing medical education curriculum, to alleviate and prevent emotional burnout,” said lead author Eduardo A. Michelen-Gómez, MD, a dermatology resident at the University of Puerto Rico School of Medicine, San Juano. “This interaction also must be designed to cater to generation and sex specific needs.”
Dr. Michelen-Gómez presented the findings at the annual meeting of the American College of Mohs Surgery.
Mohs is a demanding procedure that involves repetitive motion, strict attention to detail, and high practice efficiency, all of which must be balanced with the need to prioritize patient safety and well-being. “All of these factors predispose Mohs surgeons to be at an increased risk of physical and emotional stress,” he said.
Despite these concerns, however, the literature is limited concerning work-associated stressors among Mohs surgeons. To further explore this issue, Dr. Michelen-Gómez and colleagues conducted a survey study of ACMS members to investigate not only the prevalence of emotional and physical stressors associated with being a Mohs surgeon but also what specific actions physicians were taking to prevent and/or treat these stressors.
They designed a 21-question cross-sectional electronic survey that was sent to all active ACMS members in 2023. Outcomes evaluated were gender, years of practice, concern for and prevalence of occupational musculoskeletal disorders, emotional stress and burnout, and surgeon’s knowledge and training to manage these symptoms. A total of 473 Mohs surgeons responded.
High Prevalence of Injury and Burnout
“Almost 90% of respondents reported moderate to severe concern for occupational musculoskeletal injuries,” said Dr. Michelen-Gómez. “The prevalence of these injuries was 68%, with neck injuries being the most common complaint. Of the entire cohort, 67% have adopted ergonomic practices patterns.”
Female surgeons had a higher prevalence of musculoskeletal injuries than men, and there was no correlation between years of practice and prevalence of these injuries.
Their results also showed that 70% of respondents reported experiencing psychological and emotional stress or burnout associated with being a Mohs surgeon. The cause of emotional stress differed between men and women. “In males, the most common cause was patient care–related anxiety, while in females, it was finding an adequate work-life balance,” he said.
Surgeons with fewer years of experience were more likely to experience emotional stress (P = .01), and female surgeons had a higher prevalence of burnout and musculoskeletal disorders (71.0% and 71.4%, respectively) than male surgeons (67.7% and 65.2%, respectively).
To prevent or manage musculoskeletal injury, respondents reported using interventions such as physical therapy, yoga/stretching/Pilates, massage therapy, cupping, and using a physical trainer. Specific actions for preventing or managing emotional stress and burnout included engaging with a therapist, working with a life coach, practicing meditation or mindfulness, journaling, relying on religion or spirituality, and exercise.
However, among those who reported musculoskeletal disorders or emotional stress, only 40.56% and 46.67%, respectively, felt they had sufficient knowledge and the resources to manage them appropriately.
“In addition, we found a positive correlation between the development of psychological stress and physical issues,” said Dr. Michelen-Gómez. Future studies can include determining the most effective methods to address the emotional and physical stressors of practicing Mohs Surgery.”
Asked to comment on the study findings, Jesse M. Lewin, MD, chief of Mohs micrographic and dermatologic surgery and vice chair of surgical operations at the Icahn School of Medicine at Mount Sinai, New York City, said that the real-world take-home messages from this study are twofold.
“It is important to focus on physician wellness and prevention of burnout and physical injury to protect our physician workforce, and two, we should equip physicians-in-training with tools to protect their physical and emotional health,” he said.

PHOENIX — In addition, most surgeons did not feel prepared to manage or prevent these symptoms.
“Our study highlights the need to implement ergonomic training and emotion-focused coping skills, as part of fellowship training and the continuing medical education curriculum, to alleviate and prevent emotional burnout,” said lead author Eduardo A. Michelen-Gómez, MD, a dermatology resident at the University of Puerto Rico School of Medicine, San Juano. “This interaction also must be designed to cater to generation and sex specific needs.”
Dr. Michelen-Gómez presented the findings at the annual meeting of the American College of Mohs Surgery.
Mohs is a demanding procedure that involves repetitive motion, strict attention to detail, and high practice efficiency, all of which must be balanced with the need to prioritize patient safety and well-being. “All of these factors predispose Mohs surgeons to be at an increased risk of physical and emotional stress,” he said.
Despite these concerns, however, the literature is limited concerning work-associated stressors among Mohs surgeons. To further explore this issue, Dr. Michelen-Gómez and colleagues conducted a survey study of ACMS members to investigate not only the prevalence of emotional and physical stressors associated with being a Mohs surgeon but also what specific actions physicians were taking to prevent and/or treat these stressors.
They designed a 21-question cross-sectional electronic survey that was sent to all active ACMS members in 2023. Outcomes evaluated were gender, years of practice, concern for and prevalence of occupational musculoskeletal disorders, emotional stress and burnout, and surgeon’s knowledge and training to manage these symptoms. A total of 473 Mohs surgeons responded.
High Prevalence of Injury and Burnout
“Almost 90% of respondents reported moderate to severe concern for occupational musculoskeletal injuries,” said Dr. Michelen-Gómez. “The prevalence of these injuries was 68%, with neck injuries being the most common complaint. Of the entire cohort, 67% have adopted ergonomic practices patterns.”
Female surgeons had a higher prevalence of musculoskeletal injuries than men, and there was no correlation between years of practice and prevalence of these injuries.
Their results also showed that 70% of respondents reported experiencing psychological and emotional stress or burnout associated with being a Mohs surgeon. The cause of emotional stress differed between men and women. “In males, the most common cause was patient care–related anxiety, while in females, it was finding an adequate work-life balance,” he said.

Reimbursement for Mohs Surgery Not Keeping Up With Health Care Costs
PHOENIX — Medicare cuts, which are expected to continue, have exacerbated this issue even further.
“This ongoing downward trend in inflation-adjusted reimbursement may lead to delayed patient access to quality dermatology surgical care,” said lead study author Lily Park, DO, a resident in the Department of Dermatology, Larkin Community Hospital, Miami. “This trend will lead to reduced access.”
Dr. Park emphasized that reimbursement for Mohs surgery has also been further affected by the multiple surgery reduction rule, which is where Medicare pays less for the second and subsequent procedures performed during the same patient encounter. Reductions may be calculated in several ways, depending on what kind of procedure or service is involved.
“The Mohs surgery community needs to be aware of this financial trend and actively engage with healthcare policymakers to ensure the establishment of a sustainable payment infrastructure,” she said.
Dr. Park presented the study results at the annual meeting of the American College of Mohs Surgery.
The landscape of healthcare economics continues to evolve and has been further complicated by rising inflation. In addition, a 2% cut to the Medicare payment conversion factor was implemented in 2023, followed by a further 3.37% cut in early 2024 — which was cut by half in March 2024, with an additional cut expected this year, she noted. “This has presented more challenges for dermatologic surgeons who are already dealing with the rising healthcare costs.”
However, despite these financial challenges, there is a lack of research on physician reimbursement for dermatologic procedures, including surgery.
Decreased Reimbursement for All Procedures
Dr. Park and colleagues analyzed trends in Medicare reimbursement rates for Mohs micrographic surgery and several other common dermatologic procedures. Beginning with 2007, they calculated the inflation-adjusted values for each year’s non-facility prices for all codes except Current Procedural Terminology (CPT) codes 11102 and 11104. For those two codes, inflation-adjusted prices were based on the prices in 2019, the year when the codes were first introduced. The authors estimated the inflation adjusted value for each year based on the non-facility price for 2007, and the difference between the rate of inflation and the change in physician reimbursement over time was calculated.
The six most commonly performed procedures in 2023, ranked in descending order of frequency, were identified as CPT 17000, used for the removal of actinic keratosis; CPT 11102, used for biopsy of skin; CPT 17110, used for the destruction of benign lesions such as seborrheic keratoses and warts; CPT 17311, used for the destruction of malignant lesions (including Mohs surgery); CPT 11104, which is also related to biopsy of skin; and CPT 10060, used for incision and drainage of abscess.
Their analysis showed that all CPT codes experienced a decline when compared with their inflation-adjusted values. Both Mohs surgery (17311) and benign destruction of premalignant lesions (17000) showed a decrease of 46% in reimbursement during an inflation-adjusted 18-year time span between 2007 and 2024.
When adjusted for inflation, Dr. Park noted, reimbursement for CPT 17311 and 17000 should actually be increased by 42% and 41% in 2024, respectively. The greatest declines in reimbursement were seen during the last 4 years.
“Future legislation, such as H.R.2474, a bill proposing inflation-based updates to physician pay, would aid us in the future if implemented,” said Dr. Park.
Dangerous Trend
The finding that payments have declined for many common dermatologic procedures since 2007 “is particularly important given the rising cost of healthcare delivery,” said Jesse M. Lewin, MD, who was asked to comment on the study results. “The administrative burden of electronic medical records, filing, and following up insurance claims has necessitated the employment of more non-physician staff to support these tasks,” he told this news organization.
“Declining reimbursement for Mohs surgery and other cancer-related procedures is a dangerous trend, as the ultimate impact will be the effect it has on quality and accessibility of skin cancer care for patients,” added Dr. Lewin, chief of Mohs micrographic and dermatologic surgery and vice chair of surgical operations at the Icahn School of Medicine at Mount Sinai, New York City. “This is an important study that reinforces physician engagement in healthcare policy and legislation to advocate for our specialty and patients.”
The study was independently supported. Dr. Park and Dr. Lewin, who was not involved with the study, reported no relevant financial relationships.

Merkel Cell: Immunotherapy Not Used for Many Patients With Metastatic Disease
PHOENIX — Immunotherapy has revolutionized outcomes for patients are better at high-volume centers.
The study has important implications, said study author Shayan Cheraghlou, MD, an incoming fellow in Mohs surgery at New York University, New York City. “We can see that in a real-world setting, these agents have an impact on survival,” he said. “We also found high-volume centers were significantly more likely to use the agents than low-volume centers.” He presented the findings at the annual meeting of the American College of Mohs Surgery.
MCC is a neuroendocrine skin cancer with a high rate of mortality, and even though it remains relatively rare, its incidence has been rising rapidly since the late 1990s and continues to increase. There were no approved treatments available until 2017, when the US Food and Drug Administration (FDA) approved the immunotherapy drug avelumab (Bavencio) to treat advanced MCC. Two years later, pembrolizumab (Keytruda) also received regulatory approval for MCC, and these two agents have revolutionized outcomes.
“In clinical trial settings, these agents led to significant and durable responses, and they are now the recommended treatments in guidelines for metastatic Merkel cell carcinoma,” said Dr. Cheraghlou. “However, we don’t have data as to how they are being used in the real-world setting and if survival outcomes are similar.”
Real World vs Clinical Trials
Real-world outcomes can differ from clinical trial data, and the adoption of novel therapeutics can be gradual. The goal of this study was to see if clinical trial data matched what was being observed in actual clinical use and if the agents were being used uniformly in centers across the United States.
The authors used data from the National Cancer Database that included patients diagnosed with cancer from 2004 to 2019 and identified 1017 adult cases of metastatic MCC. They then looked at the association of a variety of patient characteristics, tumors, and system factors with the likelihood of receiving systemic treatment for their disease.
“Our first finding was maybe the least surprising,” he said. “Patients who received these therapeutic agents had significantly improved survival compared to those who have not.”
Those who received immunotherapy had a 35% decrease in the risk for death per year compared with those who did not. The 1-, 3-, and 5-year survival rates were 47.2%, 21.8%, and 16.5%, respectively, for patients who did not receive immunotherapy compared with 62.7%, 34.4%, and 23.6%, respectively, for those who were treated with these agents.
Dr. Cheraghlou noted that they started to get some “surprising” findings when they looked at utilization data. “While it has been increasing over time, it is not as high as it should be,” he emphasized.
From 2017 to 2019, 54.2% of patients with metastatic MCC received immunotherapy. The data also showed an increase in use from 45.1% in 2017 to 63.0% in 2019. “This is an effective treatment for aggressive malignancy, so we have to ask why more patients aren’t getting them,” said Dr. Cheraghlou.
Their findings did suggest one possible reason, and that was that high-volume centers were significantly more likely to use the agents than low-volume centers. Centers that were in the top percentile for MCC case volume were three times as likely to use immunotherapy for MCC compared with other institutions. “So, if you have metastatic Merkel cell carcinoma and go to a low volume center, you may be less likely to get potential lifesaving treatment,” he noted.
Implications Going Forward
Dr. Cheraghlou concluded his presentation by pointing out that this study has important implications. The data showed that in a real-world setting, these agents have an impact on survival, but all eligible patients do not have access. “In other countries, there are established referral patterns for all patients with aggressive rare malignancies and really all cancers,” he added. “But in the US, cancer care is more decentralized. Studies like this and others show that high-volume centers have much better outcomes for aggressive rare malignancies, and we should be looking at why this is the case and mitigating these disparities and outcomes.”
Commenting on the study results, Jeffrey M. Farma, MD, co-director of the Melanoma and Skin Cancer Program and professor of surgical oncology at Fox Chase Cancer Center, Philadelphia, referred to the two immunotherapies that have been approved for MCC since 2017, which have demonstrated a survival benefit and improved outcomes in patients with metastatic MCC.
“In their study, immunotherapy was associated with improved outcomes,” said Dr. Farma. “This study highlights the continued lag of implementation of guidelines when new therapies are approved, and that for rare cancers like Merkel cell carcinoma, being treated at high-volume centers and the regionalization of care can lead to improved outcomes for patients.”

The authors used data from the National Cancer Database that included patients diagnosed with cancer from 2004 to 2019 and identified 1017 adult cases of metastatic MCC. They then looked at the association of a variety of patient characteristics, tumors, and system factors with the likelihood of receiving systemic treatment for their disease.
“Our first finding was maybe the least surprising,” he said. “Patients who received these therapeutic agents had significantly improved survival compared to those who have not.”
Those who received immunotherapy had a 35% decrease in the risk for death per year compared with those who did not. The 1-, 3-, and 5-year survival rates were 47.2%, 21.8%, and 16.5%, respectively, for patients who did not receive immunotherapy compared with 62.7%, 34.4%, and 23.6%, respectively, for those who were treated with these agents.
Dr. Cheraghlou noted that they started to get some “surprising” findings when they looked at utilization data. “While it has been increasing over time, it is not as high as it should be,” he emphasized.
From 2017 to 2019, 54.2% of patients with metastatic MCC received immunotherapy. The data also showed an increase in use from 45.1% in 2017 to 63.0% in 2019. “This is an effective treatment for aggressive malignancy, so we have to ask why more patients aren’t getting them,” said Dr. Cheraghlou.
Their findings did suggest one possible reason, and that was that high-volume centers were significantly more likely to use the agents than low-volume centers. Centers that were in the top percentile for MCC case volume were three times as likely to use immunotherapy for MCC compared with other institutions. “So, if you have metastatic Merkel cell carcinoma and go to a low volume center, you may be less likely to get potential lifesaving treatment,” he noted.
Implications Going Forward
Dr. Cheraghlou concluded his presentation by pointing out that this study has important implications. The data showed that in a real-world setting, these agents have an impact on survival, but all eligible patients do not have access. “In other countries, there are established referral patterns for all patients with aggressive rare malignancies and really all cancers,” he added. “But in the US, cancer care is more decentralized. Studies like this and others show that high-volume centers have much better outcomes for aggressive rare malignancies, and we should be looking at why this is the case and mitigating these disparities and outcomes.”
Commenting on the study results, Jeffrey M. Farma, MD, co-director of the Melanoma and Skin Cancer Program and professor of surgical oncology at Fox Chase Cancer Center, Philadelphia, referred to the two immunotherapies that have been approved for MCC since 2017, which have demonstrated a survival benefit and improved outcomes in patients with metastatic MCC.
“In their study, immunotherapy was associated with improved outcomes,” said Dr. Farma. “This study highlights the continued lag of implementation of guidelines when new therapies are approved, and that for rare cancers like Merkel cell carcinoma, being treated at high-volume centers and the regionalization of care can lead to improved outcomes for patients.”

Use of Radiotherapy for Nonmelanoma Skin Cancer Increasing, Study Finds
PHOENIX — More specifically, the persistent growth in the use of superficial radiotherapy (SRT) devices and electronic brachytherapy (eBT) to treat nonmelanoma skin cancer (NMSC) has exceeded that of traditional procedures among dermatologists using these modalities, according to Christian Gronbeck, MD, a resident in dermatology at the University of Connecticut Health Center, Farmington.
“These services increased substantially over the study period,” Dr. Gronbeck said at the annual meeting of the American College of Mohs Surgery, where he presented the results of the study. “Our findings suggest that those using eBT/SRT were frequently general dermatologists and non-fellowship–trained Mohs surgeons who have less formalized surgical training.”
He also noted that billing for these services also rose substantially, which is being driven by growing utilization and an increased SRT payment rate.
Surgical approaches are standard for most NMSC cases, but some patients are not good surgical candidates because of medical comorbidities and/or other factors, and radiotherapy is emerging as a potential treatment option for those patients. Traditionally, radiotherapy was administered by radiation oncologists, but with the growing availability of SRT devices and the introduction of eBT, dermatologists are now treating patients with these modalities.
“It is a potential treatment option for nonmelanoma skin cancer and keloids, and these lower energy devices can be used in the outpatient setting,” said Dr. Gronbeck. “Treatment typically involves a series of fractions over a period of several weeks. There has been recent growth in the use of radiotherapy despite this being a secondary option in skin cancer, primarily when surgery is contraindicated.”
Steady Expansion of Use
Dr. Gronbeck and colleagues sought to gain a better understanding of the use of SRT and eBT for NMSC among dermatologists, as well as trends in cost. Data were obtained from the 2016-2021 Medicare Public Use Files to evaluate the trend in the volume of Medicare Part B claims for eBT (CPT 0394T) and SRT (CPT 77401) by dermatologists, and they also looked at related billable services for radiotherapy.
Of 12,050 dermatologists, 293 (2.4%) were identified as utilizing eBT or SRT in 2021, representing a 75.4% increase from 2016. The usage of both eBT and SRT increased by 59.6% and 148.4%, respectively, from 2016 to 2021.
There were notable geographic differences in the utilization of radiotherapy. “Florida, California, Texas, and Arizona had the highest utilization,” Dr. Gronbeck said, although during the study period, utilization increased in other states, including North Carolina and Alabama.
When looking at geographic regions as a whole, the highest number of dermatologists using radiotherapy were located in the South (n = 143, 50.9%), followed by the West (n = 69, 23.6%). Utilization was more common in metro areas than in nonmetro/rural areas (86% vs 14%).
Differences were also noted among dermatologists. Those who performed eBT/SRT than those who did not were significantly more likely to have had 15 or more years of independent practice (70.1% vs 48.6%), be in a small private dermatology practice (62.7% vs 47.5%), and be non–fellowship-trained Mohs surgeons (33.5% vs 10.2%). Dermatologists utilizing radiotherapy were also more likely to treat Medicare beneficiaries who were older, with a mean age over 75 years (39.3% vs 31.1%) and a mean hierarchical condition category (HCC) score, above the national average (55.2% vs 44.6%).
Dr. Gronbeck and colleagues also looked at cost. The number of direct payments for eBT/SRT payments increased throughout the study period, from 3,678,224 in 2016 to 11,680,925 in 2021, nearly a 218% increase. The change in payments for services related to eBT/SRT, such as radiotherapy simulation, radiotherapy dosing, and ultrasound guidance, increased by 621.4% during this same timeframe.
Radiotherapy in dermatology has primarily been assessed through retrospective studies. “Our findings suggest that eBT and SRT are more frequently utilized by dermatologists managing older and sicker patients, but further studies are needed to identify whether these interventions are truly addressing poor surgical candidates,” Dr. Gronbeck said.
The Centers for Medicare & Medicaid Services (CMS) has recently proposed changes in Medicare coverage in seven states for Image-Guided Superficial Radiation Therapy (image-guided SRT or IGSRT) for the treatment of NMSC. The proposed local coverage determination, or LCD, if finalized in its current form, would affect residents in North Carolina, South Carolina, Virginia, West Virginia, Alabama, Georgia, and Tennessee.
“These changes would mean more restrictive coverage,” said Dr. Gronbeck, and further support the need for “improved clinical data and development of guidelines to support evidence-based utilization.”
Surgical Management Standard, but SRT Has a Role
Asked to comment on the findings, Seemal R. Desai, MD, president of the American Academy of Dermatology (AAD), who was not involved with the study, reiterated that according to this abstract, efficacy has mainly been assessed through retrospective studies, and results are likely inferior to Mohs surgery, require multiple treatment visits, and are associated with significant costs. More study is needed for the use of radiation therapy in dermatology, he told this news organization.
“The Academy supports continued research and studies for therapies that can help improve patient outcomes and offer treatment options, as well as further studies on long-term outcomes for treatments like superficial radiation therapy,” he said.
“Well-designed studies can certainly be helpful to better assess efficacy and outcomes,” Dr. Desai continued. “This is why the Academy supports the idea of scientific studies that continue to expand the body of literature and data, which can help dermatologists tailor therapeutic options for their patients.”
As for general dermatologists using radiation therapy, he pointed out that SRT was developed within the dermatology specialty with dermatologists being the experts in delivering SRT for patients with NMSCs when indicated. “SRT has been used for over 100 years to treat skin cancer,” said Dr. Desai, of the department of dermatology, UT Southwestern Medical Center, Dallas. “While certain radiation devices have historically been used by dermatologists, dermatologists engaged in providing superficial radiation therapy must have adequate education and training to administer this therapy safely and effectively.”
The AAD Association (AADA) has a position statement that supports the use of SRT as an option for the treatment of basal cell carcinoma and squamous cell carcinoma in certain circumstances. “This could be when surgical intervention is contraindicated or refused and after the benefits and risk of treatment alternatives have been discussed with the patient,” he said. “Based on current evidence, surgical management remains the most effective treatment for NMSC.”
Dr. Desai added that the AADA is also concerned that if the Proposed LCD is finalized by CMS, it “could restrict dermatologists from performing SRT and impede patient access to SRT as a potential treatment when indicated.”
The study was independently supported. Dr. Gronbeck and Dr. Desai reported no relevant financial relationships.

Post–Mohs Surgery Opioid Prescribing More Common in Some Patient Groups
PHOENIX — The study also found that patients who do receive opioids postoperatively are at an increased risk for chronic opioid use and complications.
This report represents the largest analysis to date of opioid prescribing after dermatologic surgery, said lead author Kyle C. Lauck, MD, a dermatology resident at Baylor University Medical Center, Dallas, Texas. “Females, African Americans, and Latino patients may be at a higher risk of opioid prescription after dermatologic surgery. Surgeons should be aware of these populations and the risks they face when determining candidacy for postsurgical opioid analgesia.”
He presented the results at the annual meeting of the American College of Mohs Surgery.
The opioid epidemic is a concern across all areas of medicine, and the majority of opioid prescriptions in dermatology are given following surgery. Dr. Lauck noted that even though guidelines delegate opioids as second line for pain control, the existing data on opioid prescribing in dermatologic surgery is mixed. For example, some reports have shown that up to 58% of patients receive opioids postoperatively. “No consensus exists when we should routinely give opioids to these patients,” he said.
Even though most surgeons prescribe short courses of opioids, even brief regimens are associated with increased risks for overuse and substance abuse. Population-level data are limited concerning opioid prescriptions in dermatologic surgery, and in particular, there is an absence of data on the risk for long-term complications associated with use.
Certain Populations at Risk
To evaluate opioid prescription rates in dermatologic surgery, focusing on disparities between demographic populations, as well as the risk for long-term complications of postoperative opioid prescriptions, Dr. Lauck and colleagues conducted a retrospective study that included 914,721 dermatologic surgery patients, with billing codes for Mohs micrographic surgery. Patient data were obtained from TriNetX, a federated health research network.
The mean age of patients in this cohort was 54 years, and 124,494 (13.6%) were prescribed postsurgical oral opioids. The most common was oxycodone, prescribed to 43% of patients. Dr. Lauck noted that, according to their data, certain groups appeared more likely to receive a prescription for opioids following surgery. These included Black or African American patients (23.75% vs 12.86% for White patients), females (13.73% vs 13.16% for males), and Latino or Hispanic patients (17.02% vs 13.61% non-Latino/Hispanic patients).
Patients with a history of prior oral opioid prescription, prior opioid abuse or dependence, and any type of substance abuse had a significant increase in absolute risk of being prescribed postsurgical opioids (P < .0001).
The type of surgery also was associated with prescribed postop opioids. For a malignant excision, 18.29% of patients were prescribed postop opioids compared with 14.9% for a benign excision. About a third of patients (34.9%) undergoing a graft repair received opioids.
There was an elevated rate of postop opioid prescribing that was specific to the site of surgery, with the highest rates observed with eyelids, scalp and neck, trunk, and genital sites. The highest overall rates of opioid prescriptions were for patients who underwent excisions in the genital area (54.5%).
Long-Term Consequences
The authors also looked at the longer-term consequences of postop opioid use. “Nearly one in three patients who were prescribed opioids needed subsequent prescriptions down the line,” said Dr. Lauck.
From 3 months to 5 years after surgery, patients who received postsurgical opioids were at significantly higher risk for not only subsequent oral opioid prescription but also opiate abuse, any substance abuse, overdose by opioid narcotics, constipation, and chronic pain. “An opioid prescription may confer further risks of longitudinal complications of chronic opioid use,” he concluded.
Commenting on the study, Jesse M. Lewin, MD, chief of Mohs micrographic and dermatologic surgery at Icahn School of Medicine at Mount Sinai, New York City, noted an important finding of this study was the long-term sequelae of patients who did receive postop opioids.
“This is striking given that postsurgical opiate prescriptions are for short durations and limited number of pills,” he told this news organization. “This study highlights the potential danger of even short course of opiates and should serve as a reminder to dermatologic surgeons to be judicious about opiate prescribing.”
Dr. Lauck and Dr. Lewin had no disclosures.

The mean age of patients in this cohort was 54 years, and 124,494 (13.6%) were prescribed postsurgical oral opioids. The most common was oxycodone, prescribed to 43% of patients. Dr. Lauck noted that, according to their data, certain groups appeared more likely to receive a prescription for opioids following surgery. These included Black or African American patients (23.75% vs 12.86% for White patients), females (13.73% vs 13.16% for males), and Latino or Hispanic patients (17.02% vs 13.61% non-Latino/Hispanic patients).
Patients with a history of prior oral opioid prescription, prior opioid abuse or dependence, and any type of substance abuse had a significant increase in absolute risk of being prescribed postsurgical opioids (P < .0001).
The type of surgery also was associated with prescribed postop opioids. For a malignant excision, 18.29% of patients were prescribed postop opioids compared with 14.9% for a benign excision. About a third of patients (34.9%) undergoing a graft repair received opioids.
There was an elevated rate of postop opioid prescribing that was specific to the site of surgery, with the highest rates observed with eyelids, scalp and neck, trunk, and genital sites. The highest overall rates of opioid prescriptions were for patients who underwent excisions in the genital area (54.5%).
Long-Term Consequences
The authors also looked at the longer-term consequences of postop opioid use. “Nearly one in three patients who were prescribed opioids needed subsequent prescriptions down the line,” said Dr. Lauck.
From 3 months to 5 years after surgery, patients who received postsurgical opioids were at significantly higher risk for not only subsequent oral opioid prescription but also opiate abuse, any substance abuse, overdose by opioid narcotics, constipation, and chronic pain. “An opioid prescription may confer further risks of longitudinal complications of chronic opioid use,” he concluded.
Commenting on the study, Jesse M. Lewin, MD, chief of Mohs micrographic and dermatologic surgery at Icahn School of Medicine at Mount Sinai, New York City, noted an important finding of this study was the long-term sequelae of patients who did receive postop opioids.
“This is striking given that postsurgical opiate prescriptions are for short durations and limited number of pills,” he told this news organization. “This study highlights the potential danger of even short course of opiates and should serve as a reminder to dermatologic surgeons to be judicious about opiate prescribing.”
Dr. Lauck and Dr. Lewin had no disclosures.

High rate of subsequent cancers in MCC
.
In a cohort of 6,146 patients with a first primary MCC, a total of 725 (11.8%) developed subsequent primary cancers. For solid tumors, the risk was highest for cutaneous melanoma and papillary thyroid carcinoma, while for hematologic cancers, the risk was increased for non-Hodgkin lymphoma.
“Our study does confirm that patients with MCC are at higher risk for developing other cancers,” study author Lisa C. Zaba, MD, PhD, associate professor of dermatology and director of the Merkel cell carcinoma multidisciplinary clinic, Stanford (Calif.) Cancer Center, said in an interview. “MCC is a highly malignant cancer with a 40% recurrence risk.”
Because of this high risk, Dr. Zaba noted that patients with MCC get frequent surveillance with both imaging studies (PET-CT and CT) as well as frequent visits in clinic with MCC experts. “Specifically, a patient with MCC is imaged and seen in clinic every 3-6 months for the first 3 years after diagnosis, and every 6-12 months thereafter for up to 5 years,” she said. “Interestingly, this high level of surveillance may be one reason that we find so many cancers in patients who have been diagnosed with MCC, compared to the general population.”
The study was published online in JAMA Dermatology.
With the death of “Margaritaville” singer Jimmy Buffett, who recently died of MCC 4 years after his diagnosis, this rare, aggressive skin cancer has been put in the spotlight. Survival has been increasing, primarily because of the advent of immunotherapy, and the authors note that it is therefore imperative to better understand the risk of subsequent primary tumors to inform screening and treatment recommendations.
In this cohort study, Dr. Zaba and colleagues identified 6,146 patients from 17 registries of the Surveillance, Epidemiology, and End Results (SEER) Program who had been diagnosed with a first primary cutaneous MCC between 2000 and 2018.
Endpoints were the ratio of observed to expected number of cases of subsequent cancer (Standardized incidence ratio, or SIR) and the excess risk.
Overall, there was an elevated risk of developing a subsequent primary cancer after being diagnosed with MCC (SIR, 1.28; excess risk, 57.25 per 10,000 person-years). This included the risk for all solid tumors including liver (SIR, 1.92; excess risk, 2.77 per 10,000 person-years), pancreas (SIR, 1.65; excess risk, 4.55 per 10,000 person-years), cutaneous melanoma (SIR, 2.36; excess risk, 15.27 per 10,000 person-years), and kidney (SIR, 1.64; excess risk, 3.83 per 10,000 person-years).
There was also a higher risk of developing papillary thyroid carcinoma (PTC) (SIR, 5.26; excess risk, 6.16 per 10,000 person-years).
The risk of developing hematological cancers after MCC was also increased, especially for non-Hodgkin lymphoma (SIR, 2.62; excess risk, 15.48 per 10,000 person-years) and myelodysplastic syndrome (SIR, 2.17; excess risk, 2.73 per 10,000 person-years).
The risk for developing subsequent tumors, including melanoma and non-Hodgkin lymphoma, remained significant for up to 10 years, while the risk for developing PTC and kidney cancers remained for up to 5 years.
“After 3-5 years, when a MCC patient’s risk of MCC recurrence drops below 2%, we do not currently have guidelines in place for additional cancer screening,” Dr. Zaba said. “Regarding patient education, patients with MCC are educated to let us know if they experience any symptoms of cancer between visits, including unintentional weight loss, night sweats, headaches that increasingly worsen, or growing lumps or bumps. These symptoms may occur in a multitude of cancers and not just MCC.”
Weighing in on the study, Jeffrey M. Farma, MD, interim chair, department of surgical oncology at Fox Chase Cancer Center, Philadelphia, noted that MCC is considered to be high risk because of its chances of recurring after surgical resection or spreading to lymph nodes or other areas of the body. “There are approximately 3,000 new cases of melanoma a year in the U.S., and it is 40 times rarer than melanoma,” he said. “Patients are usually diagnosed with Merkel cell carcinoma later in life, and the tumors have been associated with sun exposure and immunosuppression and have also been associated with the polyomavirus.”
That said, however, he emphasized that great strides have been made in treatment. “These tumors are very sensitive to radiation, and we generally treat earlier-stage MCC with a combination of surgery and radiation therapy,” said Dr. Farma. “More recently we have had a lot of success with the use of immunotherapy to treat more advanced MCC.”

New evidence suggests genetic risk factors in hidradenitis suppurativa
Hidradenitis suppurativa (HS) is a chronic inflammatory skin condition with lesions that include deep-seated nodules and abscesses, draining tracts, and fibrotic scars, and has been reported to be highly heritable.
A genomewide association study (GWAS) that involved a meta-analysis of data from three large biobanks (UK Biobank, FinnGen, and BioVU) identified one significant locus and two suggestive loci. The researchers were able to replicate the association with HS for two loci near the SOX9 and KLF5 genes in BioVU.
In addition, they also looked at genetic correlations between HS and autoimmune and inflammatory diseases, and results suggested a positive association with inflammatory bowel disease, psoriasis, and type 2 diabetes.
However, while plausible, the variant associations near candidate genes do not prove a causal effect of these variants or genes on disease risk, and further study is needed.
“It’s possible that these genes aren’t the ones affected by the variations we describe, but both are very strong candidates,” said study author Christopher J. Sayed, MD, associate professor of dermatology, University of North Carolina at Chapel Hill. “This improves our understanding of HS as a disease that is likely related to genetic changes that result in dysregulated hair follicle maintenance, inflammation, and wound healing.”
In turn, this will allow clinicians to educate patients about the underlying genetic influences on HS, he explained, as opposed to stigmatizing misconceptions focusing only on weight, smoking, and hygiene.
“Larger studies are underway and will be needed to find variants that may predict things like disease severity and response to treatment, but this is a big first step in the right direction,” Dr. Sayed added.
The study was published online in JAMA Dermatology.
Loci identified
GWASs have been limited in HS, and previous research has not identified significant risk loci. In the current study, Dr. Sayed and colleagues sought to identify underlying genes and genetic mechanisms that may underlie pathogenesis in HS.
They performed a GWAS in a cohort of 720 patients who were part of the Hidradenitis Suppurativa Program for Research and Care Excellence (HS ProCARE) at the UNC department of dermatology, and controls from the National Longitudinal Study of Adolescent to Adult Health (Add Health) study, a U.S.-based study following adolescents through adulthood.
The UK Biobank (UKB) is a prospective biobank with about 500,000 individuals aged 40-69 years, and FinnGen collects and analyzes genome and health data from Finnish biobank participants. To increase power to detect associations, a GWAS was performed using participants from the UKB (247 HS cases, 453,048 controls). The HS ProCARE GWAS results were meta-analyzed with UKB, along with data from FinnGen (673 HS cases, 297,544 controls). This three-way meta-analysis revealed one genomewide significant locus and two suggestive loci.
The authors found that the most strongly associated variant, rs10512572 located on chromosome 17, showed the strongest association in FinnGen; at the second locus, the most strongly associated variant was rs17090189 located on chromosome 13 and also showed the strongest association in FinnGen; and at the third locus, the most strongly associated variant, rs5792315, located on chromosome 11, showed the strongest association in HS ProCARE.
Next, they tested the 10 most strongly associated variants at the three loci in the BioVU biobank, which has 290 HS cases, including 189 individuals of European ancestry and 101 individuals of African ancestry, with 64,234 and 12,105 controls, respectively. The locus on chromosome 17 was replicated in BioVU in the same direction of effect, while one variant at the chromosome 13 locus showed nominal evidence of association in the same direction.
In a four-way meta-analysis of BioVU combined with the other three studies, the chromosome locus became more significant and the chromosome 13 locus exceeded the genomewide significance threshold. In contrast, the chromosome 11 locus was not replicated in BioVU (P = .27).
The authors pointed out that variants at these loci are located in keratinocyte regulatory elements near the genes SOX9 and KLF5, which play a role in skin and follicular inflammation, but have not previously been associated with HS pathogenesis.
Finally, they looked to see if there were shared genetic components between HS and autoimmune and inflammatory diseases. A nominally significant genetic correlation was observed between HS and inflammatory bowel disease (P = .04), psoriasis (P = .03), and type 2 diabetes (P = .04), although none reached significance.
Different manifestation with genetic variant
In a related study, researchers assessed the prevalence of the NCSTN:c.671_682del variant among individuals with HS in Malta, the island country in the Mediterranean, which has a high prevalence of HS and its associated risk factors, particularly obesity.
Led by Dillon Mintoff, MD, of the department of pathology at the University of Malta, Msida, they conducted a cross-sectional study of 113 adults with HS. In this group, 14 (12.39%) were found to be heterozygous for the NCSTN:c.671_682del variant. Individuals who had this variant were more likely to develop symptoms earlier and to manifest them in atypical skin sites, including the scalp, neck, torso, and antecubital fossae. Additionally, even though their symptoms weren’t more severe than those without the variant, patients with the variant were more likely to require treatment with biologic agents.
Studies move genetics in HS forward
Writing in an accompanying editorial, Atlas Khan, PhD, and Lynn Petukhova, PhD, from Columbia University, New York, noted that both of these HS genetic studies “set a solid foundation for future studies aimed at understanding the biological and clinical relevance of new HS genetic evidence.”
“Each study suggests a series of experiments that will allow us to gain new knowledge about HS,” they wrote, including coming closer to providing patients with a genetic diagnosis.
In addition, evidence from the GWAS paper suggests that with “larger HS GWASs we will be able to better prioritize drug-repurposing studies,” concluded the editorialists. “Both of these goals will help to improve health outcomes for patients with HS and their family members.”

The HS ProCARE GWAS results were meta-analyzed with UKB, along with data from FinnGen (673 HS cases, 297,544 controls). This three-way meta-analysis revealed one genomewide significant locus and two suggestive loci.
The authors found that the most strongly associated variant, rs10512572 located on chromosome 17, showed the strongest association in FinnGen; at the second locus, the most strongly associated variant was rs17090189 located on chromosome 13 and also showed the strongest association in FinnGen; and at the third locus, the most strongly associated variant, rs5792315, located on chromosome 11, showed the strongest association in HS ProCARE.
Next, they tested the 10 most strongly associated variants at the three loci in the BioVU biobank, which has 290 HS cases, including 189 individuals of European ancestry and 101 individuals of African ancestry, with 64,234 and 12,105 controls, respectively. The locus on chromosome 17 was replicated in BioVU in the same direction of effect, while one variant at the chromosome 13 locus showed nominal evidence of association in the same direction.
In a four-way meta-analysis of BioVU combined with the other three studies, the chromosome locus became more significant and the chromosome 13 locus exceeded the genomewide significance threshold. In contrast, the chromosome 11 locus was not replicated in BioVU (P = .27).
The authors pointed out that variants at these loci are located in keratinocyte regulatory elements near the genes SOX9 and KLF5, which play a role in skin and follicular inflammation, but have not previously been associated with HS pathogenesis.
Finally, they looked to see if there were shared genetic components between HS and autoimmune and inflammatory diseases. A nominally significant genetic correlation was observed between HS and inflammatory bowel disease (P = .04), psoriasis (P = .03), and type 2 diabetes (P = .04), although none reached significance.
Different manifestation with genetic variant
In a related study, researchers assessed the prevalence of the NCSTN:c.671_682del variant among individuals with HS in Malta, the island country in the Mediterranean, which has a high prevalence of HS and its associated risk factors, particularly obesity.
Led by Dillon Mintoff, MD, of the department of pathology at the University of Malta, Msida, they conducted a cross-sectional study of 113 adults with HS. In this group, 14 (12.39%) were found to be heterozygous for the NCSTN:c.671_682del variant. Individuals who had this variant were more likely to develop symptoms earlier and to manifest them in atypical skin sites, including the scalp, neck, torso, and antecubital fossae. Additionally, even though their symptoms weren’t more severe than those without the variant, patients with the variant were more likely to require treatment with biologic agents.
Studies move genetics in HS forward
Writing in an accompanying editorial, Atlas Khan, PhD, and Lynn Petukhova, PhD, from Columbia University, New York, noted that both of these HS genetic studies “set a solid foundation for future studies aimed at understanding the biological and clinical relevance of new HS genetic evidence.”
“Each study suggests a series of experiments that will allow us to gain new knowledge about HS,” they wrote, including coming closer to providing patients with a genetic diagnosis.
In addition, evidence from the GWAS paper suggests that with “larger HS GWASs we will be able to better prioritize drug-repurposing studies,” concluded the editorialists. “Both of these goals will help to improve health outcomes for patients with HS and their family members.”

Study supports new NCCN classification for cutaneous squamous cell carcinoma
, according to new findings.
In addition, regardless of the NCCN risk group, the study found that Mohs surgery or peripheral and deep en face margin assessment (PDEMA) conferred a lower risk of developing LR, DM, and disease-related death.
“Although the NCCN included this new high-risk group in the last iteration of the guidelines, there were no studies that identified whether the high-risk group achieved the goal of identifying riskier tumors,” said senior author Emily Ruiz, MD, MPH, associate physician at the Mohs and Dermatologic Surgery Center at Brigham and Women’s Faulkner Hospital, Boston. “Based on the data in our study, the risk groups did risk stratify tumors and so clinicians can utilize the high-risk group risk factors to identify which tumors may require additional surveillance or treatment.”
The study was published online in JAMA Dermatology.
Most patients with CSCC are successfully treated with Mohs micrographic surgery or wide local excision (WLE) alone, but a subset will experience more severe and aggressive disease. While useful for prognostication, current staging systems do not incorporate patient factors or other high-risk tumor features that influence outcomes, which led to the NCCN reclassifying CSCC into low-, high-, and very high-risk groups. The NCCN guidelines also made a new recommendation that Mohs or PDEMA be the preferred method for tissue processing for high- and very-high-risk tumors, based on this new stratification.
However, these changes to the NCCN guidelines have not been validated. The goal of this study was to compare outcomes in very-high-, high-, and low-risk NCCN groups as well as comparing outcomes of CSCCs stratified by Mohs and WLE.
Dr. Ruiz and colleagues conducted a retrospective cohort study using patient data from two tertiary care academic medical centers. Their analysis included 10,196 tumors from 8,727 patients that were then stratified into low-risk (3,054 tumors [30.0%]), high-risk (6,269 tumors [61.5%]), and very-high-risk (873 tumors [8.6%]) groups.
Tumors in the very-high-risk group were more likely to have high-risk tumor and histologic features, such as large-caliber perineural invasion, large diameter, invasion beyond the subcutaneous fat or bone, poor differentiation, and lymphovascular invasion.
The authors found that, compared with the low-risk group, the high- and very-high-risk groups demonstrated a greater risk of LR (high-risk subhazard ratio, 1.99; P = .007; very-high-risk SHR, 12.66; P < .001); NM (high-risk SHR, 4.26; P = .02; very-high-risk SHR, 62.98; P < .001); DM (high-risk SHR, 2.2 × 107;P < .001; very-high-risk SHR, 6.3 × 108;P < .001); and DSD (high-risk SHR, 4.02; P = .03; very-high-risk SHR, 93.87; P < .001).
Adjusted 5-year cumulative incidence was also significantly higher in very-high- vs. high- and low-risk groups for all endpoints.
They next compared the procedures used to treat the tumors. Compared with WLE, patients treated with Mohs or PDEMA had a lower risk of LR (SHR, 0.65; P = .009), DM (SHR, 0.38; P = .02), and DSD (SHR, 0.55; P = .006).
Mohs and PDEMA have already became preferred surgical modalities for high- and very-high-risk tumors, and Dr. Ruiz pointed out that their analysis was for the entire cohort.
“We did not stratify this by risk group,” she said. “So our results do not change anything clinically at this time, but support prior studies that have found Mohs/PDEMA to have improved outcomes, compared to WLE. Further studies are needed evaluating surgical approach by risk-group.”
However, she emphasized, “our studies further validate prior evidence showing Mohs/PDEMA to have the lowest rates of recurrence and in this study, even disease-related death.”
Approached for an independent comment, Jeffrey M. Farma, MD, codirector of the melanoma and skin cancer program, and interim chair, department of surgical oncology, Fox Chase Cancer Center, Philadelphia, noted that this study supports the new reclassification of CSCC tumors by the NCCN, and confirms that the high-risk and very-high-risk tumors surely have a higher propensity for worse outcomes overall.
“That being said, the notion for type of resection and margin assessment is still an area of controversy in the dermatology, surgical oncology, and pathology community,” said Dr. Farma, who is also on the NCCN panel. “I believe we need further studies to truly understand the role of the type of resection and the pathologic evaluation play in this disease process.”
He also pointed out that it is unclear in this dataset if patients initially had any imaging to evaluate for local or regional metastatic disease. “It would be helpful to have a further understanding of which type of provider was performing the excisions, the type of excision decided upon, and if there was a standardized approach to [decide] which patients had MOHS or PDEMA and what was the surveillance for these patients both with imaging and physical examinations,” said Dr. Farma. “This data also evaluated patients over a long time period where practice patterns have evolved.”
Finally, he noted that the number of local and metastatic events subjectively seems low in this cohort. “We also do not know any information about the initial workup of the patients, patterns of recurrence, and adjuvant or palliative treatment after recurrence,” he added. “It is unclear from this manuscript how the type of resection or pathologic evaluation of margins leads to improved outcomes and further prospective studies are warranted.”
