About this trial

This is a multicenter, open-label, phase 3, randomized, non-inferiority study aimed to investigate the effect on disease-free survival of adjuvant chemotherapy with oxaliplatin plus S-1 compared with adjuvant chemotherapy with docetaxel plus S-1 after D2 gastrectomy in patients with stage III gastric cancer.

Treatments tested in this trial

  • Oxaliplatin plus S-1

    Drug

    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).

  • Docetaxel plus S-1

    Drug

    DS group: S-1 on days 1 to 14 of a 3-week cycle during the first cycle. During the second to seventh cycles, patients received intravenous infusion of docetaxel (40mg/m2) on day 1 of each cycle and S-1 on days 1 to 14 of a 3-week cycle. After the eighth cycle, treatment with S-1 continued on days 1 to 28 of 6-week cycles for up to 1 year.
