The Safety and Effectiveness of Hyperthermic Intraperitoneal Chemotherapy Combined With Intravenous Chemotherapy for Peritoneal Metastatic Pancreatic Cancer, a Phase II Clinical Trial

The goal of this clinical trial is to evaluate the effectiveness and safety of hyperthermic intraperitoneal chemotherapy combined with intravenous chemotherapy in peritoneal metastatic pancreatic cancer. The main question it aims to answer are: (1) Does this combined approach increase 1-year survival rates? and (2) What is the safety profile of this treatment regimen? Participants will: undergo baseline imaging and surgical exploration to confirm peritoneal metastasis, receive two cycles of intraperitoneal cisplatin HIPEC (70mg/m²) postoperatively, followed by systemic AG chemotherapy (nab-paclitaxel plus gemcitabine), with treatment adjustments based on regular imaging assessments and multidisciplinary team (MDT) recommendations.
