donafenib combine with sintilimab and haic (hepatic artery infusion chemotherapy，haic）in the first-line treatment of unresectable hepatocellular carcinoma

Conditions: Hepatocellular Carcinoma

Summary: the investigators design a phase iib clinical study to explore the efficacy and safety of donafenib combined with sintilimab and haic in the first-line treatment of unresectable hepatocellular carcinoma

this trial is a single-arm, non-randomized and single-center clinical study of donafenib combined with sintilimab and haic in the first-line treatment of unresectable hepatocellular carcinoma. it will estimate that 30 patients who met the study criteria will be enrolled in tianjin medical university cancer institute and hospital and treat with donafenib combined with sintilimab and haic. the investigators will follow up and collect subjects' data monthly to evaluate the efficacy and safety of treatment, including overall survival and time to progression.
