- •Normal hemodynamic indices:
- •Blood cell count: HB ≥ 90g/L, ANC ≥ 1.5×109/L, PLT ≥ 80×109/L; Liver and renal function: BIL<1.5 times of the upper limit of normal reference values, ALT and AST<2.5 times of the upper limit of normal reference values, and Crea≤1 time of upper limits of normal reference values.
- •Therapeutic response rating after neoadjuvant chemotherapy is CR, PR, SD, or Therapeutic response rating after neoadjuvant chemotherapy is PD, tumor is expected to have radical resection; Subjects are still willing to continue participating in this clinical trial.
排除标准
- •History of upper abdominal surgery (include endoscopic mucosal resection or endoscopic submucosal dissection, except for laparoscopic cholecystectomy); History of acute pancreatitis; Enlarged or bulky regional lymph node (diameter>3cm) by imaging exam; Patients have received neoadjuvant therapy prior to screen work; History of other malignant disease within the past five years; History of cerebrovascular accident within the past six months; History of continuous systematic administration of corticosteroids within the past month; Scheduled simultaneous surgery for other disease; Emergency surgery due to complication (bleeding, obstruction or perforation) caused by gastric cancer; Pyloric obstruction; FEV1<50% of predicted value; Women who are pregnant or lactating at the time of screening; Severe mental disorder; Participating in other clinical studies; Refused to sign the informed consent;
- •Therapeutic response rating after neoadjuvant chemotherapy is PD, involvement of adjacent structures(T4b), distal metastasis(M1), or enlarged or bulky regional lymph node (diameter>3cm) by preoperative imaging Patients cannot complete 3 cycles of chemotherapy due to intolerance; After 3 cycles of neoadjuvant chemotherapy, patients cannot tolerate surgery due to severe adverse reactions, or ASA score ≥ 4 ; Patients undertake emergency operation due to tumor bleeding, perforation or obstruction during chemotherapy; After signing the informed consent, the patient withdraws from this clinical trial.
