Official title

Comparison of With and Without Sequential Single Drug Therapy of S-1 After Adjuvant Chemotherapy With Docetaxel Plus S-1 in Stage III Gastric Cancer

Overview

The goal of this single arm clinical trial is to learn about sequential S-1 adjuvant therapy in patient wich locally advanced gastric cancer. The main question it aims to answer is: • The efficacy and safety of S-1 adjuvant therapy, following D2 radical surgery and DS(Docetaxel + S-1) adjuvant chemotherapy. All patients with locally advanced gastric cancer will received D2 radical surgery, 6 cycles of DS chemotherapy, and sequential S-1 chemotherapy up to 1 year postoperation.

Interventions

Drug Docetaxel
Docetaxel 40mg/m2，every 21 days，6 cycles.
Drug Tegafur-Gimeracil-Oteracil
S-1 40-60mg/m2，p.o, BID, day 1-14, till 1 year postoperation.

Primary outcome measures

Recurrence free survival [Time frame: 3 years]

Secondary outcome measures (1)

Overall survival [Time frame: up to 5 years]
