Ntraperitoneal Thermal Perfusion Combined With Chemotherapy Versus Chemotherapy

Study Overview
=================
Brief Summary
-----------------
In view of the existence of malignant ascites in patients with advanced pancreatic cancer, we put forward the heat abdominal cavity perfusion chemotherapy combined albumin paclitaxel and gemcitabine compared with albumin paclitaxel and gemcitabine prospective clinical study, to assess abdominal albumin hot perfusion chemotherapy combined control of ascites and taxol in improving patients' quality of life, survival, exploring the feasibility of celiac hot perfusion chemotherapy combined albumin paclitaxel and side effects.
