Melanoma Recurrence after Mohs Micrographic Surgery with MART-1: A Systematic Review and Meta-analysis

Abstract

Background: Surveys suggest wide-spread use of MART-1 in MMS for CM among Mohs surgeons, but no previous systematic review has investigated the efficacy of this specific procedure. Methods: A systematic search and meta-analysis of retrospective studies on MMS with MART-1 was performed from Pubmed, Medline, and Cochrane databases for articles published from their inception to October 30, 2020. We performed a chi-squared analysis of homogenized data to examine the relationship between recurrence location and rate of recurrence. A risk of bias was obtained with the ROBINS-I tool. [PROSPERO ID: CRD42020221826] Results: Among the included studies, there were a total of 15 (0.52%) local recurrences of melanoma in-situ and invasive melanoma after MMS with MART-1. Conclusions: This review has served to demonstrate that MMS with MART-1 immunostaining in frozen sections is a technique that produces satisfactory recurrence rates for melanoma in-situ and invasive melanoma.
