Summary

This study tests whether adding the immunotherapy drug sintilimab to standard chemotherapy after surgery can help prevent stage III stomach or gastroesophageal junction cancer from returning. About 70 adults who have had their tumor removed will receive the combination treatment for up to 16 cycles. Researchers will track how long participants remain cancer-free and monitor side effects.
