HAIC Plus Toripalimab vs. HAIC Plus Sorafenib for HCC With PVTT: a Non-comparative, Prospective, Randomized Trial

Hepatic Arterial Infusion Chemotherapy Plus Toripalimab Versus Hepatic Arterial Infusion Chemotherapy Plus Sorafenib for Hepatocellular Carcinoma With Portal Vein Tumor Thrombus: a Non-comparative, Prospective, Randomized Trial

The purpose of this study is to evaluate the efficacy and safety of hepatic arterial infusion chemotherapy of oxaliplatin, 5-fluorouracil and leucovorin plus toripalimab versus hepatic arterial infusion chemotherapy of oxaliplatin, 5-fluorouracil and leucovorin plus sorafenib in patients with hepatocellular carcinoma (HCC) with portal vein tumor thrombus.

Our previous study showed that hepatic arterial infusion chemotherapy (HAIC) of oxaliplatin, 5-fluorouracil and leucovorin plus sorafenib was more effective and safe than sorafenib for hepatocellular carcinoma with portal vein tumor thrombus. Programmed cell death protein-1 (PD-1) antibody was effective and tolerable in patients with advanced hepatocellular carcinoma. No study has compared HAIC plus toripalimab with HAIC plus sorafenib. Thus, the investigators carried out this prospective, randomized, non-comparative study to find out it.
