%X BACKGROUND: Immune Checkpoint Inhibitors (ICIs) are becoming a new treatment approach for patients with unresectable hepatocellular carcinoma (uHCC). However, the results regarding its efficacy compared with the standard regimen of targeted therapy are not consistent.
OBJECTIVE: Our aim was to conduct a meta-analysis of existing studies to reveal the differences in the efficacy and safety of the two systems of treatment.
METHODS: The related studies were searched in PubMed, Web of Science, the Cochrane Library, and Embase from inception to June 30th, 2022. Data on overall survival (OS), progression-free survival (PFS), objective response rate (ORR), disease control rate (DCR), and rate of treatment- related adverse events (TrAEs) with their 95% confidence intervals (CI) were pooled and analyzed by Stata 12.0 software.
RESULTS: A total of ten high-quality controlled clinical studies with 5,539 patients with uHCC were included. The hazard ratio (HR) of the OS and PFS were 0.80 (95% CI, 0.74-0.86) and 0.72 (95% CI, 0.58-0.89), respectively. In addition, the odds ratio (OR) of the ORR and DCR were 3.39 (95% CI, 2.75-4.17) and 1.20 (95% CI, 0.84-1.73), respectively. The ORR of ICIs monotherapy, ICIs plus anti-vascular endothelial growth factor (VEGF) and ICIs plus ICIs were 16% (95% CI, 0.13-0.18), 17% (95% CI, 0.10-0.27), and 20% (95% CI, 0.16-0.24), respectively. For all included studies, the OR of the overall TrAEs was 0.51(95% CI, 0.22-1.18), and grade ≥ 3 TrAEs was 0.78 (95% CI, 0.53-1.14).
CONCLUSIONS: ICIs were more effective than targeted drugs concerning survival periods and ORR in patients with uHCC while maintaining a stable safety profile.
