Arms Assigned Interventions
Experimental: 1
TS-1 and cisplatin
Drug: TS-1 and cisplatin
TS-1(40-60 mg per body surface area) was given orally, twice daily for 3 consecutive weeks, and 60 mg/m2 cisplatin was given intravenously on day 8, followed by a 2-week rest period, within a 5-week cycle.
Active Comparator: 2
TS-1
Drug: TS-1
TS-1(40-60 mg per body surface area) was given orally, twice daily for 4 consecutive weeks, followed by a 2-week rest period, within a 6-week cycle.

Detailed Description:

This is a randomized, controlled, open-label, parallel, multicenter study. Patients are stratified according to 3 factors ; performance status (ECOG scale: 0, 1, 2), disease stage (unresectable gastric cancer or recurrent gastric cancer (received prior adjuvant chemotherapy or not)) and participating center. Patients are randomized to one of two treatment arms. Arm A: Patients receive oral TS-1 twice daily on days 1-28 followed by 14 days rest. Treatment is repeated every 42 days for up to 4 courses. Arm B: Patients receive CDDP iv on day 8 and oral TS-1 twice daily on days 1-21 followed by 14 days rest. Treatment is repeated every 35 days for up to 5 courses. Patients are followed every 6 months for up to 2 years from the day they participates in this study.
