Purpose: Mohs micrographic surgery (MMS) is a low-risk penile cancer management option. However, contemporary patients' short-term oncologic control and preoperative characteristics predicting reconstruction needs are undefined. This study assesses MMS's oncologic efficacy for low-risk penile cancer and identifies baseline predictors of post-resection reconstruction referral., Methods: We retrospectively reviewed 73 adult males with 78 penile cutaneous malignancies treated with MMS from 2005 to 2019. Patients underwent MMS with or without surgical reconstruction. Demographic information, MMS operative details, lesion pathology, and short-term outcomes were recorded. Descriptive statistics for all variables were calculated, and logistic regression identified predictive factors for urologic referral for complex reconstruction., Results: Seventy-three men with 78 lesions, all staged ≤ cT1a prior to MMS, were identified. Twenty-one men were found to have invasive SCC. Median follow-up was 2.0 years (IQR 0.8-5.2 years). MMS was able to clear the disease in 90.4% of cases. One patient had disease related death following progression. Dermatology closed primarily in 68% of patients. Twenty percent of patients had a complication, most commonly poor wound healing. On univariate and multivariate linear regression analysis, lesion size > 3 cm and involvement of the glans independently predicted the need for referral to a reconstructive surgeon., Conclusions: MMS for penile cancer appears to provide sound oncologic control in the properly selected patient. Involvement of a reconstructive surgeon may be needed for glandular and large lesions, necessitating early referral to a comprehensive multidisciplinary care team., (© 2024. The Author(s).)

Objective: Among patients undergoing two-stage interpolated flap repair of nasal defects, nasal function, and appearance before surgery and at 16 weeks after flap takedown were compared using the Nasal Appearance and Function Evaluation Questionnaire (NAFEQ). Design: Multicenter prospective cohort study. Methods: Adult patients with a nasal skin cancer anticipated to require two-stage interpolation flap repair completed the NAFEQ before surgery, at 1 week after flap placement, 4 weeks after flap takedown, and 16 weeks after flap takedown. Results: One hundred sixty-nine patients were enrolled, with 138 patients completing both presurgical and 16-week post-takedown NAFEQs. Overall NAFEQ score increased by 1.09 points (1.91% improvement, confidence interval [95% CI -0.34 to 2.53]). NAFEQ functional subscale increased by 0.72 points (2.58% increase; 95% CI [0.10-1.35]) and appearance subscale increased by 0.37 points (1.28% improvement, 95% CI [-0.65 to 1.39]). Conclusion: At 16 weeks after flap takedown, patients' perceptions of their nasal function and appearance are similar to or slightly improved when compared with their presurgical assessments.

Background: Dermatologists perform most interpolated flaps after skin cancer resection. Prospective, multicenter data on complications after interpolated flap repair in this setting are limited., Objective: To determine the rate of physician-reported complications after interpolated flap repair of the nose., Methods: Multicenter, prospective cohort study of 169 patients undergoing 2-stage interpolated flap repair of post-Mohs nasal defects. Frequency of bleeding, infection, dehiscence, necrosis, hospitalization, and death in the 30 days after flap placement and flap takedown are reported., Results: Patients experienced 23 complications after flap placement (13.61%) and 6 complications after flap takedown (3.55%) that were related to the surgical procedure. The most frequent complication after flap placement was bleeding (9, 5.33%, 95% confidence interval [CI]: 2.83%-9.82%). The most frequent complication after flap takedown was infection (5, 2.96%, 95% CI: 1.27%-6.74%). There was one hospitalization related to an adverse reaction to antibiotics. There were no deaths., Conclusion: Most complications after interpolated flap repair for post-Mohs defects of the nose are minor and are associated with flap placement. Interpolated flap repair for post-Mohs defects can be performed safely in the outpatient setting under local anesthesia., (Copyright © 2022 by the American Society for Dermatologic Surgery, Inc.

Importance: Single-center studies have shown that patients report better skin cancer-specific quality of life (QOL) after Mohs micrographic surgery (MMS), but it is unclear whether this improved QOL applies to patients after MMS and complex reconstruction in cosmetically sensitive areas., Objective: To evaluate patient QOL after MMS and interpolation flap reconstruction for patients with nasal skin cancers., Design, Setting and Participants: This multicenter prospective survey study used the Skin Cancer Index (SCI), a validated, 15-question QOL questionnaire administered at 4 time points: before MMS, 1 week after flap placement, 4 weeks after flap takedown, and 16 weeks after flap takedown. Patients age 18 years or older with a nasal skin cancer who presented for MMS and were anticipated to undergo 2-stage interpolated flap repair by a Mohs surgeon were recruited from August 9, 2018, to February 2, 2020, at 8 outpatient MMS locations across the United States, including both academic centers and private practices., Main Outcomes and Measures: Mean difference in overall SCI score before MMS vs 16 weeks after flap takedown., Results: A total of 169 patients (92 men [54.4%]; mean [SD] age, 67.7 [11.4] years) were enrolled, with 147 patients (75 men [51.0%]; mean [SD] age, 67.8 [11.7] years) completing SCI surveys both before MMS and 16 weeks after flap takedown. Total SCI scores improved significantly 16 weeks after flap takedown compared with pre-MMS scores, increasing by a mean of 13% (increase of 7.11 points; 95% CI, 5.48-8.76; P < .001). All 3 SCI subscale scores (emotion, appearance, and social) improved significantly (emotion subscale, increase of 3.27 points; 95% CI, 2.35-4.18; P < .001; appearance subscale, increase of 1.65 points; 95% CI, 1.12-2.18; P < .001; and social subscale, increase of 2.10 points; 95% CI, 1.55-2.84; P < .001) 16 weeks after flap takedown compared with pre-MMS., Conclusions and Relevance: Removal of a nasal skin cancer and repair of the resulting defect can be distressing for patients. However, this cohort study suggests that physicians referring patients for MMS can be reassured that their patient's QOL will improve on average after surgery, even when a complex reconstruction is required.

Background: Antibiotics are often prescribed after dermatologic surgery for infection prophylaxis, but patient preferences about prophylactic antibiotics are not well understood., Objective: To understand patient preferences about taking antibiotics to prevent surgical site infection (SSI) relative to antibiotic efficacy and antibiotic-associated adverse drug reactions., Materials and Methods: Multi-center, prospective discrete choice experiment (DCE)., Results: Three hundred thirty-eight respondents completed the survey and DCE. 54.8% of respondents preferred to take an antibiotic if it reduced the SSI rate from 5% to 2.5% and if the risk of adverse drug reactions was low (1% risk gastrointestinal upset, 0.5% risk itchy skin rash, 0.01% risk emergency department visit). Even if an antibiotic could eliminate SSI risk (0% risk SSI) and had a low adverse drug reaction profile, 26.7% of respondents prefer not to take prophylactic oral antibiotics., Conclusion: Risk-benefit thresholds for taking antibiotics to prevent SSI vary widely. Clinical trials are needed to better characterize the effectiveness and risks of oral antibiotic SSI prophylaxis to guide decision-making. Future studies should also evaluate whether shared decision-making can improve the patient experience., (Copyright © 2021 by the American Society for Dermatologic Surgery, Inc.

Background: Local recurrence rates (LRRs) after Mohs micrographic surgery (MMS) for male genital cancers have been reported in only a few small case series, and patient-reported outcomes (PROs) have not been studied., Objective: To determine the LRR and PROs after MMS for male genital skin cancers., Methods: Retrospective review of all male genital skin cancers removed with MMS between 2008 and 2019 at an academic center. LRR was determined by chart review and phone calls. PROs were assessed by survey., Results: A total of 119 skin cancers in 108 patients were removed with MMS. Tumors were located on the penis (90/119) and scrotum (29/119). Diagnoses included squamous cell carcinoma in situ (n = 71), invasive squamous cell carcinoma (n = 32), extramammary Paget disease (n = 13), melanoma (n = 2), and basal cell carcinoma (n = 1). The LRR was 0.84% (1/119), with a mean follow-up time of 3.25 years (median, 2.36 years). The majority of survey respondents reported no changes in urinary (66%) or sexual functioning (57.5%) after surgery., Limitations: Retrospective single-center experience; short follow-up time; low survey response rate; no baseline functional data., Conclusion: MMS for male genital skin cancer has a low LRR and high patient-reported satisfaction with urinary and sexual function., Competing Interests: Conflicts of interest None disclosed., (Copyright © 2020.

Background: Antibiotic prescriptions associated with dermatologic surgical visits are increasing and prescribing practices vary among surgeons., Objective: To describe dermatologic surgeons' attitudes and practices regarding prophylactic antibiotic use for surgical site infection (SSI), to compare current prescribing practices to those of a 2012 survey, and to determine surgeons' interest in clinical trial data on the utility of prophylactic antibiotics., Materials and Methods: This was a cross-sectional online survey of the American College of Mohs Surgery (ACMS) members. Survey items were adapted from a 2012 survey of ACMS members., Results: The survey was initiated by 101 ACMS members. 75.25% (76/101) of surgeons reported routinely prescribing prophylactic antibiotics to reduce SSI risk. The use of prophylactic antibiotics varied with clinical scenario. Most providers (84.21%, 64/76) prescribe postoperative antibiotics, with an average course of 6.56 days. 40.21% (39/97) of respondents were uncertain if prophylaxis prevents SSI, and up to 90.63% (87/96) indicated interest in clinical trial data evaluating the efficacy of oral antibiotics for SSI prevention., Conclusion: Dermatologic surgeons continue to report varied attitudes and practices for SSI prophylaxis. Evidence from clinical trials is desired by surgeons to guide clinical practice., (Copyright © 2020 by the American Society for Dermatologic Surgery, Inc. Published by Wolters Kluwer Health, Inc.

Importance: Defining which populations are affected by basal cell carcinoma (BCC) vs cutaneous squamous cell carcinoma (cSCC) may inform targeted public health strategies. Incidence of BCC and cSCC is not reported to national cancer registries, but claims data for the treatment of BCC and cSCC provide insights into the epidemiology of keratinocyte carcinoma., Objective: To define differences in the ratio of BCC to cSCC in adults (age, ≥18 years) in a large database of patients with commercial insurance and Medicare Advantage coverage., Design, Setting, and Participants: This cross-sectional analysis used deidentified data derived from the Optum Clinformatics Data Mart to perform a retrospective evaluation of a large commercially insured cohort based on treatment claims from January 1, 2012, to December 31, 2016. Patients with a diagnosed and treated BCC or cSCC as determined by codes from the International Classification of Diseases, Ninth Revision, International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, and Current Procedural Terminology were included. Data were analyzed from November 30, 2019, to March 20, 2020., Exposure: Diagnosis and treatment of BCC or cSCC., Main Outcomes and Measures: The ratio of BCC to cSCC based on age, sex, race, and geographic location. Multivariable logistic regression was used to assess how demographics were associated with the odds of a treated keratinocyte carcinoma being a BCC., Results: Among the 985 317 claims for patients included in the analysis (61.59% for men; mean [SD] age, 69.82 [12.58] years), BCCs were 1.69 (95% CI, 1.6899-1.6901) times more likely than cSCCs to be treated in the United States from 2012 to 2016. Basal cell carcinomas were significantly more prevalent than cSCCs in younger patients (18-39 years, 9.63 [95% CI, 9.6088-9.6574] BCCs per cSCC; 40-64 years, 2.92 [95% CI, 2.9171-2.9187] BCCs per cSCC; and ≥65 years, 1.33 [95% CI, 1.3289-1.3291] BCCs per cSCC; P < .001). Basal cell carcinomas were significantly more prevalent than cSCCs in women vs men, except in adults 65 years or older (odds ratios [ORs], 0.98 [95% CI, 0.97-0.99] vs 1.67 [95% CI, 1.47-1.88] for those aged 18-39 and 1.15 [95% CI, 1.12-1.19] for those aged 40-64 years; P < .001). The difference in BCC:cSCC ratios between men and women diminished with increasing age (OR, 1.67 for 18-39 years, 1.15 for 40-64 years, and 0.98 for 65 years or older). Basal cell carcinoma was more prevalent than cSCC in all races, including Black patients (BCC:SCC ratios, 1.60 for Asian patients, 1.45 for Black patients, 2.00 for Hispanic patients, and 1.69 for White patients of all ages). The BCC:cSCC ratio varied based on geography, with the highest ratio in the West North Central census division (2.12) and the lowest ratio in the South Atlantic census division (1.35)., Conclusions and Relevance: In the absence of a national registry, claims data can improve our understanding of the epidemiology of keratinocyte carcinomas. In this cross-sectional study, basal cell carcinomas were more common than cSCCs for all demographics, including in Black patients. In populations younger than 40 years, BCCs were 12.6 times more likely for women and 7.2 times more likely for men. These demographic groups may benefit from public health education focused on the presentation and management of BCCs.
