Postoperative Chemoradiotherapy With S-1 in Gastric Cancer

April 3, 2013 updated by: Sang-Hee Cho, Chonnam National University Hospital

A Phase II Study of Adjuvant S-1/Cisplatin Chemotherapy Followed by S-1-based Chemoradiotherapy in Advanced Gastric Cancer

This study was conducted to evaluate the clinical outcomes and toxicities of adjuvant treatment including S-1/cisplatin chemotherapy followed by S-1 based CRT.

Detailed Description

Surgery is the only possible curative treatment of gastric cancer. However, the high recurrence rate makes gastric cancer a disease difficult to cure by surgery alone. Despite the benefit of CRT on local recurrence, the distant recurrence is the leading pattern of failure. We hypothesized that gastric cancer outcome could be improved using a more effective chemotherapy regimen. This study was conducted to evaluate the clinical outcomes and toxicity of adjuvant treatment including S-1/cisplatin chemotherapy followed by S-1 based CRT.

Participant Group / Arm
Intervention / Treatment
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.
