Description for medicine or protocol of treatment in detail:

 

纳入标准:

1.临床诊断为Ⅱ-Ⅳa期胃腺癌及食管胃结合部腺癌(Siewert II/III型)的患者,经病理组织活检确认; 2.年龄18-75岁,东部合作肿瘤学组(Eastern Cooperative Oncology Group,ECOG)疾病状况评分为0-1; 3.预计生存期为>=12个月; 4.无胸腔、腹盆腔积液,腹盆部CT证实无转移至腹膜、肝脏或其他远处器官; 5.自愿参与签署知情同意书,表现出良好的依从性和配合意愿以配合随访; 6.拟接受新辅助药物治疗,行根治性手术切除术患者。

Inclusion criteria

1. Patients clinically diagnosed with stage II–IVa gastric adenocarcinoma and adenocarcinoma of the esophagogastric junction (Siewert II/III), confirmed by pathological tissue biopsy; 2. Aged 18–75 years, Eastern Cooperative Oncology Group (ECOG) performance status 0–1; 3. Expected survival >=12 months; 4. No pleural, abdominal, or pelvic effusion, and abdominal-pelvic CT confirms no metastasis to the peritoneum, liver, or other distant organs; 5. Voluntarily willing to sign the informed consent form, demonstrating good compliance and cooperation for follow-up; 6. Intended to receive neoadjuvant drug therapy and undergo radical surgical resection.

排除标准:

1.怀孕或哺乳期妇女; 2.五年内接受过抗肿瘤治疗; 3.术后病理发现阳性切缘; 4.五年内患有其他恶性肿瘤病史; 5.不能控制的胸腔积液、心包积液或腹水; 6.严重未控制的并发感染或其他严重未控制的合并症或疾病,使受试者不适合参加研究,或任何严重的医学紊乱会影响受试者的安全性; 7.患者需紧急手术,或存在胃癌引起的出血、梗阻等并发症; 8.临床上严重的心脏病或肺功能障碍; 9.拒绝提供血液、组织样本; 10.无能力或因道德、医学原因不适合继续进行研究; 11.其他被认为可能影响患者安全性或试验遵从性的情况。

History of other malignant tumors within the past five years; 5. Uncontrolled pleural effusion, pericardial effusion, or ascites; 6. Severe uncontrolled concurrent infection or other severe uncontrolled comorbidities or diseases that make the subject unfit to participate in the study, or any serious medical disorder that may affect the safety of the subject; 7. Patients requiring emergency surgery, or with complications such as bleeding or obstruction caused by gastric cancer; 8. Clinically severe heart disease or pulmonary dysfunction; 9. Refusal to provide blood or tissue samples; 10. Unable or considered unsuitable for continuing the study due to ethical or medical reasons; 11. Other conditions considered likely to affect patient safety or trial compliance.
