Brief Summary
Perioperative chemotherapy improves overall survival (OS) and disease-free survival (DFS) compared with surgery alone in patients with resectable gastric adenocarcinoma (GA) or gastro-oesophageal junc...
Detailed Description
This study will evaluate the pathologic complete response rate of a perioperative chemotherapy combined with tislelizumab and Trastuzumab in patients with resectable gastric cancer. Prior to surgery t...
Eligibility Criteria
Inclusion
- Key

- CT2-4CN any C M0 or T any CN +M0, AJCC/UICC TNM staging of gastric cancer (8th edition).
- The HER2 receptor protein status was assessed by immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH) using the following methods.Tumors with an IHC 3+ score are considered HER2-positive.Patients with immunohistochemical 2+ tumors were given FISH tests to determine FISH positive samples.
- Abdominal computed tomography (CT), abdominal, pelvic, and/or echo-endoscopy were performed 2 weeks before surgery to assess resectability.
