November 8, 2022 updated by: Xiangdong Cheng, Zhejiang Cancer Hospital

A Retrospective Study of Sintilimab Combined With Chemotherapy in Conversion Therapy of Unresectable Locally Advanced or Stage IV Gastric Cancer/Gastroesophageal Junction Carcinoma

This study was an observational, non-interventional, multicenter retrospective study to evaluate the feasibility and safety of sintilimab combined with chemotherapy (SOX or PS) in the clinical practice of unresectable locally advanced or stage IV gastric cancer/gastroesophageal junction carcinoma.
