Arms of the Study
Arm 1
Experimental
S-1,chemoradiotherapy, adjuvant treatment
Pts with radically D2 resected adenocarcinoma of the stomach or GEJ in AJCC stage Ib-IV (M0) were eligible for this study. Pts were treated with S-1 (40-60 mg depending on BSA) b.i.d. for 3 wks, and cisplatin (60 mg/m²) iv on day 1, followed by a 2-wk rest period, within a 5-wk cycle. Subsequently, radiotherapy (RT) started which consisted of 25 fractions of 1.8 Gy to a total dose of 45 Gy in 5 wks (5 fractions/wk). On RT days, S-1 (40-60 mg depending on BSA ) b.i.d., 5 days/wk was given. One month after the completion of RT, two 5-wk cycles of S-1/ciplatin chemotherapy were given.
