A retrospective case series of Mohs micrographic surgery and interdisciplinary management of female genital skin cancers: Local recurrence rates and patient-reported outcomes

Abstract

Conventional excision of female genital skin cancers has high rates of local recurrence and morbidity. Few publications describe local recurrence rates (LRRs) and patient-reported outcomes (PROs) after Mohs micrographic surgery (MMS) for female genital skin cancers. To evaluate LRRs, PROs, and interdisciplinary care after MMS for female genital skin cancers. A retrospective case series was conducted of female genital skin cancers treated with MMS between 2006 and 2021 at an academic center. The primary outcome was local recurrence. Secondary outcomes were PROs and details of interdisciplinary care. Sixty skin cancers in 57 patients were treated with MMS. Common diagnoses included squamous cell cancer (n=26), basal cell cancer (n=12), and extramammary Paget disease (n=11). Three local recurrences were detected with a mean follow-up of 61.1months (median: 48.8months). Thirty-one patients completed the PROs survey. Most patients were satisfied with MMS (71.0%, 22/31) and reported no urinary incontinence (93.5%, 29/31). Eight patients were sexually active at follow-up and 75.0% (6/8) experienced no sexual dysfunction. Most cases involved interdisciplinary collaboration 71.7% (43/60). Limitations include the retrospective single-center design, heterogeneous cohort, and lack of preoperative function data. Incorporating MMS into interdisciplinary teams may help achieve low LRRs and satisfactory function after genital skin cancer surgery.
