Brief summary: Hepatocellular carcinoma (HCC) is one of the most common malignant tumors, with more than 700,000 new cases in the world every year. China has the highest incidence and death rate of HCC in the world, accounting for 55% of the world's annual incidence and 45% of the world's annual deaths. At present, surgical resection is still one of the most effective treatments for HCC. However, the recurrence rate of tumor after hepatectomy is still very high, and the recurrence rate of 5 years is 60\~70%. Especially in patients with high-risk recurrence factors, without intervention, the cumulative recurrence rate in the first year was about 50%, about 60% in the second year, about 70% in the third year, and about 80% in the fifth year. Tumor recurrence is an important bottleneck that hinders the long-term survival of patients. Therefore, there is an urgent need for effective adjuvant therapy to reduce the postoperative recurrence rate of patients with HCC, especially high-risk patients. However, there is still a lack of standard protocols for postoperative adjuvant therapy for HCC. Here investigators intend to explore the safety and efficacy of Donafinib Combined With Anti-PD-1 Antibody as postoperative adjuvant therapy for HCC patients with high risks of recurrence.

Detailed description: This is a single center, open, single arm, and exploratory study. Thirty HCC patients with high risk recurrence factors after radical surgery will be enrolled. Adjuvant treatment of Donafenib combined with anti-PD-1 antibody will be given for 6 months. The primary endpoint is the cumulative percentage of patients without recurrence in the first year. The recurrence-free survival (RFS), overall survival (OS), tumor recurrence time (TTR), ECOG physical condition (ECOG PS) score, the changes of FACT-Hep based quality of life score, changes of AFP, and adverse events will be recorded and analyzed, to evaluated the efficacy and safety of this combination treatment.

And during the study, antiviral drugs should be continued, and liver function and hepatitis B virus load should be monitored;
