Kaplan-Meier analyses of disease-free survival (DFS) of 450 patients with stage I-III melanoma received definitive therapy according to different stratums by prognostic factors (overall comparison was performed by Mantel-Cox log-rank test): (A) Male vs. Female (P = .035), (B) DFS estimates according to stage (P < .001), (C) DFS of patients receiving different excision (EE for extended excision, LE for local excision, LND for lymph node dissection) of primary tumor (P < .001), (D) DFS of patients receiving different adjuvant therapy (P < .001).
