Interventions

DRUG

Oxaliplatin plus S-1

SOX group: eight 3-week cycles of intravenous oxaliplatin (130mg/m2 on day 1 for each cycle) with orally S-1 dose dependent on body surface area (\<1.24 m2, 40mg twice a day; 1.25-1.5 m2, 50mg twice a day; \>1.5m2 60mg twice a day, days 1 to 14 of each cycle).

DRUG

Docetaxel plus S-1
