Overall Survival After Mohs Surgery for Early-Stage Merkel Cell Carcinoma
Cheraghlou, Shayan; Doudican, Nicole A; Criscito, Maressa C; Stevenson, Mary L; Carucci, John A
IMPORTANCE/UNASSIGNED:Merkel cell carcinoma (MCC) is a rare cutaneous malignant neoplasm with increasing incidence and high mortality. Although it is accepted that the optimal treatment for localized tumors is surgical, the data surrounding the optimal surgical approach are mixed, and current National Comprehensive Cancer Network guidelines state that Mohs micrographic surgery (MMS) and wide local excision (WLE) can both be used. The current National Comprehensive Cancer Network guidelines do not advocate a preference for MMS or WLE and suggest that they can be used interchangeably. OBJECTIVE/UNASSIGNED:To evaluate the association of surgical approach with overall survival after excision of localized T1/T2 MCC. DESIGN, SETTING, AND PARTICIPANTS/UNASSIGNED:This retrospective cohort study used the National Cancer Database to assess adults with T1/T2 MCC who were diagnosed between January 1, 2004, and December 31, 2018, with pathologically confirmed, negative regional lymph nodes and treated with surgery. The National Cancer Database includes all reportable cases from Commission on Cancer-accredited facilities. Data analysis was performed from October 2022 to May 2023. EXPOSURE/UNASSIGNED:Surgical approach. MAIN OUTCOMES AND MEASURES/UNASSIGNED:Overall survival. RESULTS/UNASSIGNED:A total of 2313 patients (mean [SD] age, 71 [10.6] years; 1340 [57.9%] male) were included in the study. Excision with MMS had the best unadjusted survival, with mean (SE) survival rates of 87.4% (3.4%) at 3 years, 84.5% (3.9%) at 5 years, and 81.8% (4.6%) at 10 years vs 86.1% (0.9%) at 3 years, 76.9% (1.2%) at 5 years, and 60.9% (2.0%) at 10 years for patients treated with WLE. Patients treated with narrow-margin excision had similar survival as those treated with WLE, with mean (SE) survival rates of 84.8% (1.4%) at 3 years, 78.3% (1.7%) at 5 years, and 60.8% (3.6%) at 10 years. On multivariable survival analysis, excision with MMS was associated with significantly improved survival compared with WLE (hazard ratio, 0.59; 95% CI, 0.36-0.97; P = .04). High-volume MCC centers were significantly more likely to use MMS over WLE compared with other centers (odds ratio, 1.99; 95% CI, 1.63-2.44; P < .001). CONCLUSIONS AND RELEVANCE/UNASSIGNED:In this cohort study, the use of MMS (compared with WLE) was associated with significantly improved survival for patients with localized MCC with pathologically confirmed negative lymph nodes treated with surgery. These data suggest that Mohs surgery may provide a more effective treatment for MCC primary tumors than conventional WLE, although the lack of randomization and potential for selection bias in this study highlight the need for future prospective work evaluating this issue.

Assessing Rates of Positive Surgical Margins After Standard Excision of Vulvar Melanomas
Cheraghlou, Shayan; Doudican, Nicole A; Criscito, Maressa C; Stevenson, Mary L; Carucci, John A
BACKGROUND:Vulvar melanoma is a rare malignancy with frequent recurrence and poor prognosis. National guidelines recommend wide local excision of these tumors with allowances for narrower margins for anatomic and functional limitations, which are common on specialty sites. There is presently a lack of data of margin positivity after standard excision of vulvar melanomas. OBJECTIVE:We aim to evaluate the rate of positive margins after standard excision of vulvar melanomas. MATERIALS AND METHODS/METHODS:Retrospective cohort study of surgically excised vulvar melanomas from the NCDB diagnosed from 2004 to 2019. RESULTS:We identified a total of 2,226 cases. Across surgical approaches and tumor stages, 17.2% (Standard Error [SE]: 0.8%) of cases had positive surgical margins. Among tumor stages, T4 tumors were most commonly excised with positive margins (22.9%, SE: 1.5%). On multivariable survival analysis, excision with positive margins was associated with significantly poorer survival (Hazard Ratio 1.299, p = .015). CONCLUSION/CONCLUSIONS:We find that positive margin rates after standard excision of vulvar malignancies are higher than for other specialty site melanomas. Our data suggest that use of surgical approaches with complete margin assessment may improve local control and functional outcomes for patients with vulvar melanoma as they have for patients with other specialty site melanomas.

Staged melanoma excision requires larger margins for tumor clearance and results in low rates of recurrence
Himeles, Jaclyn Rosenthal; Criscito, Maressa C; Lee, Nayoung; Stevenson, Mary L; Carucci, John A
There is controversy regarding the optimal surgical modality and ideal recommended margins for treating melanoma in situ (MIS) and invasive melanoma (IM). Although wide local excision is recommended, staged excision offers excellent margin control and low recurrence rates. In this manuscript, we reviewed a 10-year experience of staged excisions for the treatment of MIS and IM. A retrospective review was performed of 130 MIS and 32 IM cases treated with staged excision from April 2012 to April 2022. Staged excision was performed on the head and neck in 102 (79%) MIS and 23 (72%) IM cases. Approximately 10% of cases required surgical margins above the current recommendations (11 (9%) MIS and 6 (19%) IM). Twenty-three (19%) MIS and 7 (22%) IM cases required more than one excision to obtain clearance. Recurrence rates among MIS and IM were 0.0% and 0.6%, respectively. Upstaging occurred in 5 (4%) MIS and 7 (22%) IM cases. Complex repairs were performed on 82 (63%) MIS and 17 (53%) IM cases. Our findings revealed that staged excision provides effective margin control and low recurrence rates. Approximately 10% of patients required margins greater than the current recommendations, leading to larger defects and more complex repairs.

Applying Occam's Razor and Descending the Reconstructive Ladder: The Modified Cheek Advancement Flap for Reconstruction of Nasal Defects
Rosenthal Himeles, Jaclyn; Criscito, Maressa; Kellner, Rebecca; Lee, Nayoung; Stevenson, Mary L; Sclafani, Anthony P; Carucci, John A
INTRODUCTION/BACKGROUND:Nasal reconstruction has important functional and cosmetic considerations, as proper repair of nasal defects is necessary to maintain function of the nasal airway and to recreate the normal appearance of this central facial structure. Cheek advancement flaps provide matched, mobile and highly vascularized tissue for the reconstruction of nasal defects, allowing for the concealment of incisions within natural creases in a one-stage approach. However, cheek advancement flaps are often underutilized for nasal reconstruction because of their difficulty restoring nasal contour. METHODS:We describe reconstruction of 19 nasal dorsal and sidewall defects 0.8 to 3.0 centimeters (cm) in size. We incorporated a periosteal anchoring suture to maintain/restore nasal contour and additionally removed a half standing cone inferior to the defect to prevent encroachment of the nasal ala or alar crease. All patients were evaluated at least 3 months post-operatively. RESULTS:In all patients, we were able to restore concavity of the nasofacial sulcus, preserve the biconvex nasal tips, prevent alar flaring and retraction and conserve the alar groove. All patients had excellent functional and cosmetic outcomes. CONCLUSION/CONCLUSIONS:We believe this modified cheek advancement flap provides functionally and aesthetically superior results and can be considered as a first-line approach for repair of nasal dorsal and sidewall defects in sub selected patients.

Deliberate practice-based surgical curriculum leads to enhanced technical proficiency among dermatology residents
Criscito, Maressa C; Wilken, Reason; Stevenson, Mary L; Carucci, John A
Deliberate practice-based medical education has demonstrated superiority in trainee acquisition and maintenance of skills in several surgical subspecialties. In an effort to highlight the impact of a deliberate practice-based surgical curriculum on the technical proficiency of dermatology residents, a prospective cohort study including first- and second-year dermatology residents was performed. A total of 87.5% (7 of 8) first-year dermatology residents completed three hands-on simulations at 6-week intervals. Additionally, six of eight (75.0%) second-year dermatology residents at the same institution were evaluated at a single point-in-time session without accessing the surgical curriculum prior. A 5-point global rating scale (GRS) was used to assess resident performance on six core surgical techniques. Nonparametric ANOVA statistical methods using the Kruskal-Wallis test was performed. The residents' overall GRS increased from a median of 1-2.75 after completion of the curriculum (p < 0.01). There was a significant improvement in the median scores of each tested surgical technique. The first-year residents had a greater overall GRS after completion of the curriculum compared to the second-year residents (median of 2.13 versus 1.88, p < 0.001). Limitations include the small sample size and lack of a synchronized control group. Our study highlights the use of deliberate practice-based strategies as an effective modality in teaching surgical skills to dermatology residents.
