Brief Summary
The purpose of this study is to explore the effectiveness and safety of immunotherapy (Adebrelimab, a PD-L1 inhibitor) combined with standard chemotherapy (XELOX) in the perioperative treatment of resectable esophagogastric junction adenocarcinoma.
Eligibility Criteria
Inclusion Criteria: * Sign on the informed consent form (ICF) * Histologically confirmed esophagogastric junction Adenocarcinoma (AEG, Type Siewert I/II/ III), the stage is locally advanced cT1b-2N+ or T3-4Nany that the investigator judges it to be resectable (1. CT or MRI assessment shows no invasion of adjacent organs or tissues, 2. No peritoneal metastasis occurs, 3. There are surgical indications) (Note: If bone lesions are suspected, a bone scan is required; if peritoneal carcinomatosis is suspected, laparoscopy is required to confirm; if T3-T4 subjects have diffuse tissue types, diagnostic laparoscopy is also required)) * No previous systematic treatment * At least one measurable lesion according to RECIST 1.1. * ECOG PS: 0-1 * The functions of important organs meet the following requirements：Absolute neutrophil count ≥ 1.5 × 109/L； Platelet ≥ 100 × 109/L； Hemoglobin ≥ 90g / l; ALT and AST ≤ 2.5 times ULN; TBIL ≤ 1.5 times ULN; Serum creatinine ≤ 1.5 times ULN or creatinine clear
