Abstract

Background

Programmed death-1 inhibitors plus lenvatinib and transarterial chemoembolization (TACE) (P–L–T) is a novel combination strategy. This systematic review and meta-analysis aimed to evaluate the efficacy and safety of P–L–T compared with lenvatinib and TACE (L–T) therapy in patients with unresectable hepatocellular carcinoma.

Methods

A systematic literature search of the PubMed, Embase, Web of Science and Cochrane Library databases for studies investigating P–L–T therapy was performed. Data regarding outcome data, including overall survival (OS), progression-free survival (PFS), tumor response, and adverse events (AEs), were independently extracted by two authors using a standardized protocol.

Results

Eight cohort studies comprising 847 patients (P–L–T: 416, L–T: 431) were included in the meta-analysis. The P–L–T group exhibited significantly longer OS (hazard ratio (Page et al.) 0.51 [95% confidence interval (CI) 0.42–0.62]; I2 = 9.8%; p = 0.354] and PFS (HR 0.51 [95% CI 0.43–0.61]; I2 = 0%; p = 0.824), and higher objective response rate (risk ratio [RR] 1.54 [95% CI 1.33–1.78]; I2 = 0%, p = 0.858]) and disease control rate (RR 1.27 [95% CI 1.17–1.38]; I2 = 17.3%; p = 0.467). Grade 3/4 AEs were more prevalent in the P–L–T group, including hypertension (RR 1.91 [95% CI 1.16–3.15]), vomiting or nausea (RR 2.29 [95% CI 1.01–5.19]), and hypothyroidism (RR 12.21 [95% CI 1.63–91.23]).

Conclusion

Compared with L–T combination therapy, P–L–T demonstrated a significant advantage in terms of OS, PFS, objective response rate, disease control rate, and manageable AEs.
