This study aimed to compare the safety and efficacy of TACE plus lenvatinib (TACE-lenvatinib) with TACE alone for patients with unresectable hepatocellular carcinoma (HCC).Methods: Between June 2019 and September 2021, a total of 215 patients diagnosed with unresectable HCC were retrospectively reviewed, including 53 patients who received TACE-lenvatinib and 162 patients who received TACE alone. The patient selection bias between the TACE-lenvatinib group and the TACE group was balanced by propensity score matching analysis at a 1:2 ratio. Progression-free survival (PFS), overall survival (OS) and tumor response were evaluated in the two groups.Results: After propensity score matching analysis, 34 patients receiving TACE-lenvatinib and 68 patients receiving TACE alone were enrolled. The median PFS and OS times in the TACE-lenvatinib group were significantly greater than those in the TACE group (PFS: 8.3 months vs 4.6 months, P = 0.008; OS: 27.7 months vs 18.4 months, P = 0.043). The objective response rate (ORR) in the TACE-lenvatinib group was higher than that in the TACE alone group (64.1% vs 36.5%, P = 0.002). Univariate and multivariate analyses revealed that TACE-lenvatinib treatment was an independent favorable prognostic factor for both PFS and OS.Conclusion: For unresectable HCC patients, the TACE-lenvatinib appeared superior to TACE alone regarding tumor control, PFS, and OS. However, considering the limitations of this study, these results should be interpreted as preliminary and warrant further confirmation.Keywords: carcinoma, hepatocellular, chemoembolization, therapeutic, lenvatinib, survival analysis, propensity score
