Prognostic factors for survival in gastric cancer after radical resection: A retrospective study of 1,594 patients in Shanghai.

e14575 Background: Gastric Cancer (GC) is the second leading cause of cancer death in Shanghai,and the overall treatment response remains poor. This study aimed to describe overall survival and identify prognostic factors for survival among GC patients (pts) after radical resection. Methods: Clinical data of 1594 GC pts (Shanghai residents) who had undergone R0 or R1 resection in Zhongshan hospital, January 2003 to June 2010, were analyzed. Potential prognostic factors including demographic and tumor characteristics were collected. Survival was calculated by the Kaplan-Meier method and Log-rank test was used to determine statistical significance. Prognostic factors were analyzed using Cox regression multivariate analysis. Results: Overall 5-year cumulative survival for all pts was 55.8%. The 5-year cumulative survival by TNM stage I, II, III, and IV (classified using AJCC 7th edition staging system) were 93.8%, 72.7%, 33.3%, and 12.7%, respectively. The distribution of pts by AJCC stage I-IV was 22.5%, 23...
