AG vs mFOLFIRINOX as Neoadjuvant Therapy for Borderline Reseactable and Locally Advanced Pancreatic Cancer

Three hundred patients with borderline resectable and locally advanced pancreatic cancer will be randomized 1:1 (150 :150) to the AG and mFOLFIRINOX chemotherapy groups and to observe the overall survival. The AG regimen: albumin-bound paclitaxel and gemcitabine are given intravenous infusion, repeated every 4 weeks for 1, 8, and 15 days, for a total of 4 to 6 cycles. MFOLFIRINOX: Intravenous oxaliplatin for 2 hours, day 1;Intravenous infusion of calcium formyl tetrahydrofolate (LV) for 2 h, day 1;Irinotecan intravenous infusion is added 30 minutes later for 90 minutes, day 1;Intravenous infusion of 5-fluorouracil (5-FU) continued for 46 hours.Repeat every 2 weeks for a total of 4-6 cycles. After neoadjuvant chemotherapy, the surgery will be evaluated according to the patient's tumor and systemic condition. The first cycle of adjuvant chemotherapy begins 4-8 weeks after radical resection, and the choice of adjuvant chemotherapy regimen depends on the response to neoadjuvant chemotherapy.If neoadjuvant chemotherapy is effective, adjuvant chemotherapy maintains the original regimen.Adjuvant chemotherapy has 4 cycles of treatment. Relevant examinations were performed before and after each cycle of medication to assess safety events, imaging review was performed every 2 cycles during the treatment period and every 3 months during the follow-up period.
