Brief Summary:

Objectives: The purpose of this study was to assess the long-term follow-up of the overall and melanoma-specific survival in the randomised, open-lable multicenter trial (NTC NCT01183936) comparing excision margin of 2 cm versus 4 cm for patients with primary cutaneous malignant melanoma (CMM) thicker than 2 mm.

Study hypothesis: The hypothesis is that there is no difference between the two treatment arms measured as melanoma-specific survival and overall survival.
