Study arms

  • Active comparator
    FLOT+Sintilimab

    Patients in the FLOT group received 4 cycles of standard FLOT chemotherapy, the FLOT chemotherapy cycle consists of: day 1: intravenous 5-FU 2600 mg/m² inserted through a peripherally inserted central catheter (PICC) for 24 hours intravenous folic acid 200 mg/m2 intravenous OXA 85 mg/m² intravenous TXT 50 mg/m². The next cycle of chemotherapy was repeated on day 15. Sintilimab: 200 mg every 3 weeks.

    Drug: FLOT+Sintilimab

  • Experimental
    SOX+Sintilimab

    Patients in the SOX group received 3 cycles of S-1 + OXA chemotherapy prior to radical gastrectomy.The SOX chemotherapy cycle consists of: day 1: intravenous OXA 130 mg/m² days 1-14: oral S-1 80 mg/m², 2 times/Day. Repeat next chemotherapy on day 22. Sintilimab: 200 mg every 3 weeks.

    Drug: SOX+Sintilimab

Interventions

  • DrugSOX+Sintilimab

    Patients would be allocated to the SOX+Sintilimab group.

  • DrugFLOT+Sintilimab

    Patients would be allocated to the FLOT+Sintilimab group.

    Time frame: From the preoperative chemotherapy until the occurrence of adverse events, assessed up to 180 days

  2. disease-free survival

    from diagnosis to recurrence or death

    Time frame: From date of diagnosis until the first documented recurrence or death, assessed up to 60 months
