Donafenib Combine With Sintilimab and HAIC in Neoadjuvant of Resectable Hepatocellular Carcinoma

This trial is a single-arm, non-randomized and single-center clinical study of Donafenib combined with Sintilimab and HAIC in Neoadjuvant of Resectable Hepatocellular CarcinomaIt will estimate that 30 patients who met the study criteria will be enrolled in Tianjin Medical University Cancer Institute and Hospital and neoadjuvant in Donafenib combined with Sintilimab and HAIC. The investigators will follow up and collect subjects' data monthly to evaluate the efficacy and safety of treatment.
