Abstract
Recently, a prospective randomized study suggested that transcatheter arterial chemoembolization (TACE) plus lenvatinib, as opposed to TACE plus sorafenib, was an effective and promising treatment for patients with advanced hepatocellular carcinoma (HCC) having portal vein thrombus (PVTT) and large tumor burden. However, no propensity score matching retrospective studies on TACE with drug-eluting beads (DEB-TACE) plus lenvatinib (DEB-TACE+LEN) versus DEB-TACE plus sorafenib (DEB-TACE+SOR) for advanced HCC has been reported to date. The medical records of consecutive patients with advanced HCC who underwent DEB-TACE+LEN or DEB-TACE+SOR between January 2017 and December 2020 were retrospectively reviewed. Mutation genes (VEGF, ANG2, FGF19, FGF21, and FGF23) were measured by whole-exome sequencing (WES). Adverse events (AEs), objective response rate (ORR), disease control rate (DCR), overall survival (OS) and time to progression (UP) were compared between patients who underwent DEB-TACE+LEN and DEB-TACE+SOR. In total, 150 patients were enrolled in this study. The DEB-TACE+LEN group (n=50) showed significantly better ORR (64.0% vs. 33.3%; P=0.008), OS (hazard ratio [HR]=0.63, 95% confidence interval (CI): 0.41-0.98; P=0.043), and UP (HR=0.65, 95% CI: 0.45-0.94; P=0.023) than that in the DEB-TACE+SOR group (n=100). Subgroup analyses showed that in patients with portal vein tumor thrombus (PVTT), OS and TTP were significantly longer in the DEB-TACE+LEN group than in the DEB-TACE+SOR group (HR=0.59, 95% CI: 0.36-0.98; P=0.043; H R=0.89, 95% CI: 0.35-2.29; P=0.035). In patients with FGF21 amplification, OS was also significantly longer in the DEB-TACE+LEN group than that in the DEB-TACE+SOR group (HR=0.19, 95% CI: 0.06-0.66; P=0.003). The patients in DEB-TACE+LEN group had a significantly lower incidence of hand-foot skin reaction (32.0% vs. 49.0%; P=0.048), but a higher incidence of proteinuria (26.0% vs. 10.0%; P=0.010) than that in the DEB-TACE+SOR group. In conclusion, DEB-TACE+LEN conferred better ORR, OS and UP than did DEB-TACE+SOR in patients with advanced HCC, especially those with PVTT and FGF21 amplification, with acceptable AEs; thus making it a superior treatment modality for these patients.
