Brief summary: This study was designed to evaluate the effectiveness and safety of hepatic arterial infusion chemotherapy combined with Bevacizumab and Sintilimab (Triplet-combined Therapy) for Unresectable A-staged Hepatocellular Carcinoma in BCLC classification.

The primary outcome measure is to evaluate the objective response rate (ORR RECIST 1.1) of Triplet-combined Therapy for Unresectable A-staged Hepatocellular Carcinoma in BCLC classification.

The secondary Outcome measures include the objective response rate (ORR mRECIST 1.1), duration of response (DOR), disease control rate (DCR), progression-free survival rate (PFSR) \[ Time Frame: 6- and 12-month\], overall survival rate (OSR) \[ Time Frame: 6- and 12-month\], the median progression-free survival time (mPFS) and median overall survival time (mOS) of Triplet-combined Therapy for Unresectable A-staged Hepatocellular Carcinoma in BCLC classification.

Moreover, this study aims to assess the safety and tolerability of Triplet-combined Therapy for Unresectable A-staged Hepatocellular Carcinoma in BCLC classification.

Detailed description: Primary liver cancer is a common malignant tumor of the digestive system in the world. There are about 854,000 new incidences and 810,000 mortality each year. In China, there is a high incidence of liver cancer, with about 466,000 new cases and 422,000 mortality each year. Hepatocellular carcinoma (HCC) accounted for about 90% of primary liver cancer in pathological type. Most patients have reached advanced stage or are unresectable when diagnosed and the natural median survival time is only 3 to 4 months. Then only systemic therapy is recommended for patients in advanced HCC in many global guidelines. Hepatic arterial infusion chemotherapy (HAIC) of mFOLFOX7, anti-angiogenic targeting drugs, and antibody immunotherapy against programmed death molecule-1 (PD-1) immunological checkpoints are effective treatment options for advanced hepatocellular carcinoma. Many clinical studies have shown that the two-two combination of the above three treatment options can improve the anti-tumor overall response rate, the survival rate and even achieve clinical complete remission of patients with unresectable HCC. Shi Ming et al reported HAIC combined with systemic targeted therapy has a better survival outcome compared to systemic targeted therapy monotherapy \[OS 13.37 vs 7.13 months, PFS 7.03 vs 2.6 months\] in JAMA Oncology. In summary, for patients of unresectable Hepatocellular Carcinoma, HAIC, antiangiogenic targeted therapy, and anti-PD-1 immunotherapy have their important status, and the combination of any two treatments brings about synergy effect. Then, could the combination of the three treatment methods further improve the outcome of unresectable hepatocellular carcinoma? This study was designed to evaluate the efficacy and safety of a combination of hepatic arterial infusion chemotherapy, targeted drugs (Apatinib), and anti-PD-1 immunotherapy (Camrelizumab) to provide a more effective and toxic-tolerable treatment for patients in unresectable A-staged Hepatocellular Carcinoma in BCLC classification. This is a single-arm phase II study, and 30 patiented will be enrolled. The patients will receive Hepatic Arterial Infusion(mFOLFOX7) on the first day, and intravenous infusion of Bevacizumab on the 4th day, and intravenous infusion of Sintilimab on the 25th day. The intervention is repeated every 3 weeks. The primary outcome measure is ORR by RECIST 1.1.
