HAIC Plus A+T for Patients With High-risk HCC: a Single-arm Phase 2 Trial

Atezolizumab plus bevacizumab is the first-line treatment for patients with advanced hepatocellular carcinoma. However, the prognosis for high-risk hepatocellular carcinoma is still poor, with a median overall survival of 7.6 months. Hepatic arterial infusion chemotherapy of oxaliplatin, 5-fluorouracil and leucovorin is effective in large hepatocellular carcinoma or hepatocellular carcinoma with major portal vein tumor thrombus. Our previous showed that hepatic arterial infusion chemotherapy plus lenvatinib and toripalimab (programmed cell death protein-1 antibody) had a powerful anti-tumor effect for high-risk hepatocellular carcinoma, with a median overall survival of 18 months. Thus, the purpose of this study is to evaluate the efficacy and safety of hepatic arterial infusion chemotherapy of oxaliplatin, 5-fluorouracil and leucovorin plus atezolizumab plus bevacizumab for patients with high-risk hepatocellular carcinoma.
