Objectives of Study:

Primary Objective: To assess the safety and antitumor activity of perioperative chemotherapy compared with perioperative chemotherapy combined with PD-1 inhibitor treatment for locally advanced gastro-esophageal junction cancer. Additionally, to explore the safety and antitumor activity of long-course neoadjuvant chemotherapy combined with PD-1 inhibitor treatment compared with perioperative chemotherapy for locally advanced esophagogastric junction adenocarcinoma. Exploratory Objectives: 1.To evaluate the correlation between the expression of Programmed Death-Ligand 1 (PD-L1) in tumor tissue, Epstein-Barr Virus (EBV) expression in tumor tissue, Microsatellite Instability (MSI) status, and the antitumor response. 2.To assess the correlation between circulating tumor DNA (ctDNA) in blood and antitumor response. 3.To evaluate the correlation between tumor tissue mutations, single-cell sequencing, RNA expression, and proteomics with the antitumor response. 4.To explore other potential immune-related biomarkers predictive of antitumor response.

随机方法(请说明由何人用什么方法产生随机序列):

根据肿瘤部位(Siewert I 型 vs Siewert II/III 型)及 Lauren 分型(弥漫型vs 肠型/混合型)分层因素,根据临床试验随机化系统(IWRS),将按照 1:1:1 比例随机分组,受试者将接受围手术期化疗(A 组)、常规新辅助的围手术期化疗联合 PD-1 抑制剂治疗(B 组)或者长程新辅助的围手术期化疗联合 PD-1 抑制剂治疗(C 组)。

Randomization Procedure (please state who generates the random number sequence and by what method):

Based on tumor location (Siewert Type I vs Siewert Type II/III) and Lauren classification (diffuse type vs intestinal/mixed type) as stratification factors, subjects will be randomized in a 1:1:1 ratio according to the Interactive Web Response System (IWRS). Subjects will receive perioperative chemotherapy (Group A), standard neoadjuvant perioperative chemotherapy combined with PD-1 inhibitor treatment (Group B), or long-course neoadjuvant perioperative chemotherapy combined with PD-1 inhibitor treatment (Group C).
