National utilization patterns of Mohs micrographic surgery for invasive melanoma and melanoma in situ.

Background: Although wide local excision continues to be commonly used for melanoma treatment, Mohs micrographic surgery (MMS) for the treatment of melanomas remains controversial.

Objective: We sought to determine national utilization patterns for MMS in the treatment of invasive melanoma and melanoma in situ.

Methods: A retrospective analysis of patients receiving surgical excision (MMS or wide local excision) for the treatment of invasive melanoma and melanoma in situ was performed using data from the National Cancer Institute Surveillance, Epidemiology, and End Results (SEER) program.
