Clinicopathologic and survival differences between upper and lower extremity melanomas.

This analysis was performed to compare differences in clinicopathologic factors, sentinel lymph node (SLN) status, and survival between upper extremity (UE) and lower extremity (LE) melanoma patients. Post hoc analysis of a prospective clinical trial was performed of all patients with extremity melanomas with complete data. Survival was evaluated with Kaplan-Meier analysis.
