Abstract
One hundred and twelve curatively resected gastric adenocarcinomas were studied retrospectively to appreciate the survival factors. Twenty different criteria (clinic, histologic and therapeutic parameters) were assessed using univariate and then multivariate analysis (semi parametric regression (COX's) model). Only three criteria were very important according to the multivariate analysis: 1) invasion of neighboring organs (p less than 0.006) with a relative risk score (RRS) of 4.26; 2) intravascular or intralymphatic tumor embols outside the tumor (p less than 0.004; RRS = 2.11); 3) invaded distal nodes (located at the origin of the vessels (p less than 0.04; RRS = 1.88). A prognosis index was described according to these results. A repartition of the patients in three prognostic groups according to these 3 criteria was proposed. Future, trials should consider these three different prognostic groups.
