Effect and Safety of Huaier Granule Versus SOX Regimen in Gastric Cancer Patients

Huaier granule, oral administration, 10g each time, 3 times a day. Continuous medication until disease progression, the end of the study, intolerable toxicity, withdrawal from the study for any reason or death, or until the researcher determines that the participants will no longer benefit, whichever occurs first. After disease progression, whether to continue the medication or not should be determined by the researcher and participant together. Participants will start taking Huaier granule within 1 to 3 weeks after surgery.

Participants will receive intravenous infusion of 130 mg/m² oxaliplatin on the first day of treatment cycle.

Participants will receive oral Tegafur, Gimeracil and Oteracil Potassium (40 mg/m², twice a day) for 2 weeks, followed by 1 week of rest.
