Using the Kaplan-Meier method, the overall 1-, 2-, and 5-year survival rates were 48.1%, 19.9%, and 16.0%, respectively. Overall median survival was 10.3 months. For resectable gastric cancer with stage I and II PC, the 1-, 2-, and 5-year survival rates were 71.3%, 37.8%, and 30.2%, respectively, with median survival of 19.0 months, whereas for stage III and IV PC, the 1- and 2-year survival rates were 32.0% and 8.0%, respectively, with median survival of 6.6 months (P = .004) (Figure 2). For patients with CCR-0 or CCR-1, the 1-, 2-, and 5-year survival rates were 74.8%, 36.8%, and 29.4%, respectively, with median survival of 21.3 months, and for patients with CCR-2, the 1-year survival rate was 15.8%, with nobody alive at 2 years and median survival of 6.6 months (P<.001) (Figure 3). Among the different variables tested using univariate analysis, the presence of preoperative ascites, unresectable primary tumor, stage III or IV PC, and CCR-2 had a significant negative effect on survival. Survival rates were higher with adjuvant treatment than without, but this difference was not significant (P = .88). Multivariate analysis using a logistic regression model was performed to determine which clinical variables were most strongly correlated with survival. All clinical variables that were close to significance (P<.10) by univariate analysis were included in the model. The CCR category and the presence of preoperative ascites had a significant effect on survival (P<.001 and P = .04, respectively).
