Brief Summary:

This is a randomized, multicenter, controlled trial to prove efficacy of S‐1 and Oxaliplatin as Neoadjuvant Chemotherapy for Advanced Gastric Cancer Patients who undergo D2 gastrectomy.

The primary endpoint is three-year free disease and the second primary includes five-year overall survival, safety and R0 resection rate.

Arm Intervention/treatment
Experimental: Arm A:Neoadjuvant sox
Patients in arm a will receive (N=2-4) cycles of neoadjuvant SOX first, and then standard gastrectomy with D2 lymphadenectomy, and (8-N) cycles of adjuvant SOX adjuvant chemotherapy.
Drug: Oxaliplatin+S-1
S-1: 40~60mg bid,po, d1~14 (S-1:BSA <1.25m2, 40mg bid, 1.25m2≤BSA≤1.5m2,50mg bid, BSA>1.5m2, 60mg bid) oxaliplatin:130mg/m2,iv drip for 2h,d1
Other Names:
  • Oxaliplatin(Sanofi-aventis)
  • S-1(Taiho)

Active Comparator: Arm B:Adjuvant SOX
Patients in arm B will receive standard gastrectomy with D2 Lymphadenectomy first, and 8 cycles of adjuvant SOX later.
Drug: Adjuvant Oxaliplatin/S-1(SOX)
S-1:40~60mg bid,d1~14 q3W oxaliplatin:130mg/m2,iv drip for 2h,d1,q3W 8 cycles (6 months)
Other Names:
  • Oxaliplatin(Sanofi-aventis)
  • S-1(Taiho)

Primary Outcome Measures :
  1. disease free survival [ Time Frame: three years ]
    SOX regimen as Neoadjuvant chemotherapy for AJCC II-III gastric cancer patients is superior than postoperative SOX after D2 surgery.Disease free survival is defined as time of surgery to recurrence or death.

Secondary Outcome Measures :
  1. response rate [ Time Frame: 3 months ]
    For neoadjuvant chemotherapy patients,response rate will be evaluated according to RECIST 1.1 criteria after at least 2 cycles of SOX chemotherapy.CT scan is required to every patient.

  2. overall survival [ Time Frame: five years ]
    Neoadjuvant chemotherapy of SOX is superior than postoperative SOX after D2 dissection in AJCC II-III gastric cancer patients.Overall survival is defined as the time of randomization to death.

  3. safety [ Time Frame: six months ]
    Number of participants with adverse events related to SOX chemotherapy.All adverse events are from CTCAE 4.0 criteria.
