Analysis of Mohs Micrographic Surgery Over 5 Years in Single Institution Center

Background: Mohs micrographic surgery (MMS) is a unique minimal marginal surgery that offers cure rates superior to other treatments of skin cancers. Our purpose was to report our experience with MMS for treatment of skin cancers, the clinical characteristics, and recurrence rates of the skin cancers, and MMS operation times. Methods: We retrospectively evaluated 293 patients who were diagnosed with skin cancer and treated by MMS and several reconstructive methods from May 2010 to April 2015. Results:The male-female patient ratio was 0.47:1, and mean patient age was 70.88 years (male, 69.98 years; female, 72.2 years). The most frequent age group was the seventh decade (36%). The most common cancer was basal cell carcinoma (57.3%), followed by squamous cell carcinoma (42.7%). The most commonly involved site was the face (80.8%), particularly the nose. Local flap was the most common method of repairing surgical defects (79.8%), followed by primary closure (13%). Recurrence after MMS was observed in 3 of 293 patients (1.0%). The minimum and maximum MMS operative times were 65 and 251 minutes, and the mean operative time was 131 minutes. The mean operative time per stage was 46.7, 43.6, and 40.0 minutes for the first, second, and third, respectively. Image studies for cancer metastasis revealed lymph node enlargement in 6 patients. Conclusion: MMS is a reliable and satisfactory method for treatment of skin cancer, and offers a low recurrence rate.
