A new article published online in February explores the outcomes of Melanoma In Situ (MIS) when teated with Mohs Micrographic Surgery vs. Wide Local Excision. The take home message from this study is that the Mohs Micrographic Surgery (MMS) is at least as effective as wide local excision (WLE), (with the potential added benefit of possibly sparing more normal tissue that Mohs Micrographic Surgery always offers). The study looked at the results of MMS treated MIS and compared them to the results of WLE treated MIS and found that tumors treated with MMS only recurred at a rate of 5 in 277, versus tumors treated with WLE which reoccurred every 22 in 385. The study was conducted with 662 patients with MIS between 1978 and 2013 with follow up’s performed through 2015. This study is important as MIS is becoming more and more prevalent and WLE is currently the primarily recommended standard of care.
