| Summary: | Abstract Background The efficacy of adding programmed death-1 (PD-1) inhibitors to transcatheter arterial chemoembolization (TACE) combined with apatinib for advanced hepatocellular carcinoma (HCC) remains controversial. This study aimed to evaluate the efficacy of incorporating PD-1 inhibitors into TACE combined with apatinib. Methods Relevant literature on TACE combined with apatinib plus PD-1 inhibitors for advanced HCC was searched in PubMed, Cochrane Library, Embase, and Web of Science databases. Trial sequential analysis (TSA) was conducted to minimize randomization errors and assess whether the meta-analysis provided conclusive evidence. Results Six studies involving 1,452 patients were included. Compared with the TACE combined with apatinib treatment group (T-A), TACE combined with apatinib plus PD-1 inhibitors (T-A-P) significantly prolonged overall survival (OS) (Hazard Ratio [HR] 2.22, 95% Confidence Interval [CI] 1.93–2.56; p < 0.001) and progression-free survival (PFS) (HR 2.36, 95% CI 2.01–2.77; p < 0.001), while also improving the objective response rate (ORR) (risk ratios [RR] 1.60, 95% CI 1.20–2.14; p < 0.001) and disease control rate (DCR) (RR 1.06, 95% CI 1.00–1.12; p < 0.001). TSA results indicated that additional studies were required to confirm the significance of DCR. Prognostic analysis identified treatment regimen and extrahepatic metastasis as common independent risk factors for OS and PFS. The incidence of adverse events in the T-A-P treatment group was comparable to that in the T-A treatment group. Conclusion Adding PD-1 inhibitors to TACE combined with apatinib significantly prolonged OS and PFS, particularly in patients without extrahepatic metastases. It also improved ORR and DCR in patients with HCC. |
