Camrelizumab combined with transcatheter arterial chemoembolization for intermediate or advanced hepatocellular...

This review assesses the efficacy and safety of the combination of transarterial chemoembolization (TACE) and camrelizumab for treating advanced hepatocellular carcinoma (HCC) and is to provide a goal, evidence-based medical foundation for effectively guiding clinical practice.

We conducted a computerized search of six electronic databases to identify studies pertinent to the combination of TACE and camrelizumab for treating advanced HCC. For further analysis of clinical indicators and adverse events data, we utilized random or fixed-effect models to account for heterogeneity between studies.

As of May 30, 2023, 12 articles were included for Meta-analysis, encompassing 1123 patients with advanced HCC. The results indicated that the combined objective response rate (ORR) and disease control rate (DCR) were 51.1 % and 86.8 %, respectively. Regarding survival indicators, the combined overall survival (OS) and progression-free survival (PFS) were 24.26 months and 11.84 months, respectively. Among the adverse events observed, the highest incidence rates for TACE combined with camrelizumab were fever (all grade: 46.5 %, ≥grade III: 5.0 %), hypertension (all grade: 32.2 %, ≥grade III: 8.5 %), transaminase elevation (all grade: 34.7 %, ≥grade III: 13.4 %), and nausea and vomiting (all grade: 43.9 %, ≥grade III: 2.5 %).

This study demonstrated the efficacy and safety of combining TACE with camrelizumab in treating patients with advanced HCC, providing valuable evidence for its prospective clinical application. However, due to the limited availability of clinical data, it is essential to design larger-scale and multi-center clinical randomized controlled trials in the future to validate and confirm these findings definitively.
