Text: Four independent prognostic factors were identified by multivariate analysis of both preoperative and postoperative factors : pathological curability B (pB ; R0 with stage IV or pD < pN) or pC [microscopic or macroscopic residual tumor (R1/R2)] [vs. pA (R0) ; HR 1. 93, p = 0. 015], pathological stage N1 (vs. pN0 ; HR 3. 86, p = 0. 0012), cT3 (vs. cT1-2 ; HR 2. 80, p = 0. 0073), and serum Alb < 4. 0 g/dl (vs. 4. 0 g/dl ; HR 2. 03, p = 0. 0069).
