Efficacy and safety of immune checkpoint inhibitors plus antiangiogenic agents for chronic hepatitis B-associated unresectable hepatocellular carcinoma
Objective This study aimed to investigate the efficacy and safety of immune checkpoint inhibitors combined with antiangiogenic agents for patients with chronic hepatitis B associated-unresectable hepatocellular carcinoma (uHCC). Methods Eighty-five patients with uHCC who were hospitalized in Beijing You'an Hospital,Capital Medical University from July 2019 to July 2023 and treated with immune checkpoint inhibitors plus antiangiogenic agents were enrolled. A retrospective study was conducted to analysis the efficacy and safety with clinical data. Results Eighty-five patients with chronic hepatitis B associated-uHCC included 65 males and 20 females,with a median age of 60.0 years old. 54 cases (63.5%) were China Liver Cancer Staging (CNLC) Ⅲ,37 (43.5%) were vascular invasion,37 (43.5%) were distant metastases and 28 (32.9% ) were Child-Pugh B and C diseases. After treatment,6 cases (7.1%) had complete responses,28 (32.9%) had partial responses,and the objective response rate reached 40.0%. The median progression-free survival was 5.8 months (95% CI:4.0-7.7),and the median overall survival was 25.8 months (95% CI:16.4-35.2). Univariate analysis showed that the median OS of the subgroups of patients who were under 55 years old,Child-Pugh BC diseases,vascular invasion and CNLC Ⅲ-Ⅳ were significantly lower than that of patients who were over 55 years old,Child-Pugh A disease,no vascular invasion and CNLC Ⅰ-Ⅱ(P<0.05). The overall safety profile was good,with a grade ≥3 adverse event rate of 32.9%. Conclusions The combination of immune checkpoint inhibitor and antiangiogenic agents can prolong the survival of the patients with chronic hepatitis B associated-uHCC and show a good safety.
