Abstract

Purpose

Hepatic arterial infusion chemotherapy (HAIC) combined with lenvatinib (Len) and immune checkpoint inhibitor (ICI) in treating advanced hepatocellular carcinoma (HCC) still needs further confirmation. We aimed to evaluate the efficacy of HAIC combined with Len and ICI (HAIC + Len + ICI) versus Len alone in advanced HCC.

Methods

A total of 290 patients in Len group and 349 patients in HAIC + Len + ICI group were analysed. Propensity score matching (PSM), inverse probability treatment weighting (IPTW), and coarsened exact matching (CEM) analyses were used to balance the bias between two groups. Mediation analysis of treatment type in survival was performed for analysis.

Results

The median progression-free survival (PFS) was 5.9 ± 0.2 months in Len group and 9.2 ± 0.5 months in HAIC + Len + ICI group. The HAIC + Len + ICI group demonstrated significantly better PFS than the Len group across the entire cohort (hazard ratio [HR], 0.50; 95% CI 0.43–0.60; P < 0.001). This advantage in PFS was sustained in the PSM, IPTW, and CEM cohorts. HAIC + Len + ICI group also showed better overall survival (OS) than the Len group (HR, 0.38; 95% CI 0.31–0.46; P < 0.001). The OS was also superior in the PSM, IPTW, and CEM cohorts. The objective response rate (ORR) in HAIC + Len + ICI group was twice as high as that in Len group. Further mediation analysis showed tumor response at 3 and 6 months had different mediation effect on survival.

Conclusions

HAIC combined with Len and ICI showed improved better OS and PFS than Len alone. This triple therapy could be considered as a first-line treatment for advanced HCC.
