haic with oxaliplatin, 5-fu and bevacizumab plus intravenous toripalimab for advanced btc

Conditions: Advanced Biliary Tract Cancer

Summary: hepatic arterial infusion chemotherapy (haic) deliver high concentration of chemotherapeutic agents directly to the liver tumor, was proved to be effective for intrahepatic and perihilar cholangiocarcinoma. based on the potential synergistic effect of bevacizumab, chemotherapy and pd-1 inhibitor, this phase ii clinical study want to test the efficacy and safety using intra-arterial infusion of oxaliplatin, 5-fluorouracil and bevacizumab combined with intravenous infusion of pd-1 inhibitor (toripalimab) in the treatment of unresectable biliary malignant tumors.
