Compare S-1 for 6 Months to 1 Year as Adjuvant Chemotherapy After D2 Resection in Patients With Gastric Cancer Staged II , IIIA or IIIB.

Summary

The study aims to compare the efficacy and safety of S-1 for 6 months versus S-1 for 1 year as adjuvant chemotherapy after D2 resection in patients with gastric cancer. Hypothesis: For gastric patients after D2 resection, S-1 for 6 months shows non-inferiority to S-1 for 1 year in disease free survival(DFS), overall survival (OS) and safety.
