We are planning pooled analyses for ACTS-GC, CLASSIC, and SAMIT trials to identify prognostic factors for patients with gastric cancer curatively treated by D2 gastrectomy; and predictive factors in adjuvant chemotherapy and in each regimen for those patients. Postoperative survival prediction models will also be developed for patients treated by adjuvant chemotherapy.
Efficacy

Relapse-free survival and overall survival according to treatment groups and trials will be described by Kaplan-Meier methods. Distributions of clinical and pathological factors will be described as well and will be compared across trials by ANOVA or the Fisher exact tests. For adjuvant groups, hazard ratios of capecitabine and oxaliplatin in CLASSIC vs. S-1 in ACTS-GC, and paclitaxel then S-1 in SAMIT vs. S-1 in ACTS-GC will be estimated by Cox regression adjusted for clinical and pathological factors.
Predictive factors for adjuvant chemotherapy will be identified by examining the difference in relapse-free survival or overall survival between treatment groups, i.e. adjuvant plus surgery vs. surgery alone, in all combined patients of ACTS-GC, CLASSIC, and SAMIT. Relapse-free survival and overall survival according to treatment groups and subgroups (defined based on the clinical and pathological factors) will be described by Kaplan-Meier methods. The hazard ratios, 95% confidence intervals, and p values of the treatment groups will be estimated by stratified Cox regression using trial as the stratified factor. Tests for treatment-subgroup interactions will be examined by stratified Cox regression including a treatment-subgroup interaction as a covariate and trial as the stratified factor. The hazard ratios, 95% confidence intervals, p values and the baseline survival functions of the final models which include significant interactions will be estimated and a postoperative survival prediction model will be developed based on the estimates.
