Abstract
AIMS: To investigate the efficacy and safety of lenvatinib and idarubicin-loaded drug-eluting beads transarterial chemoembolization (IDADEB-TACE) in primary advanced hepatocellular carcinoma (HCC). METHODS: This retrospective study included patients with primary advanced HCC who received either lenvatinib monotherapy or lenvatinib plus IDADEB-TACE as first-line treatment from September 2019 to September 2020 at three institutes. Overall survival (OS), time to progression (TTP), objective response rate (ORR), and adverse events were compared. Propensity score-matching was used to reduce the influence of confounding factors on the outcomes. RESULTS: The study reviewed 118 patients who received lenvatinib plus IDADEB-TACE (LIDA group) and 182 who received lenvatinib alone (LEN group). After propensity score-matching, 78 pairs of patients remained. Compared to patients in the LEN group, those in the LIDA group had better post-treatment ORR (57.7% vs. 25.6%, p < 0.001, respectively), median OS and TTP (15.7 vs. 11.3 months, hazard ratio [HR] = 0.50, p < 0.001; 8.0 vs. 5.0 months, HR = 0.60, p = 0.003, respectively), 6- and 12-month OS rates (88.5% vs. 71.4%; 67.6% vs. 43.4%, respectively), and progression-free rates at 6 and 12 months (60.3% vs. 42.3%; 21.1% vs. 10.3%, respectively). Vascular invasion, α-fetoprotein level, and treatment type were independent OS predictors, and vascular invasion and treatment type were independent TTP predictors. Incidences of nausea/vomiting, fever, abdominal pain, and increased ALT/AST were higher in the LIDA group than in the LEN group. CONCLUSIONS: Lenvatinib plus IDADEB-TACE is well-tolerated and more effective than lenvatinib monotherapy in patients with advanced HCC.
