Abstract
PURPOSE: This study aimed to explore the clinical efficacy of transarterial chemoembolization (TACE) in combination with tyrosine kinase inhibitors (TKIs) plus immune checkpoint inhibitors (ICIs) (triple therapy) compared to TACE alone (monotherapy) for advanced hepatocellular carcinoma (HCC). MATERIAL AND METHODS: Data of consecutive advanced HCC patients receiving triple therapy or monotherapy at our center between January 2019 and December 2022 were collected and retrospectively analyzed. Propensity score matching (PSM) and subgroup analyses were performed to reduce the bias between the two groups. The primary outcomes of the study were the overall survival (OS) and progression-free survival (PFS). The secondary outcomes were the objective response rate (ORR) and disease control rate (DCR). RESULTS: A total of 104 patients were enrolled in this study: 41 in the triple therapy group and 63 in the monotherapy group. After PSM analysis, each group included 37 patients. The median OS and PFS were significantly longer in the triple therapy group than in the monotherapy group in the whole cohort (median OS, 18.8 vs 11.7 months, P = 0.022; median PFS, 10.5 vs 6.4 months, P = 0.012) and after PSM (median OS, 19.6 vs 12.5 months, P = 0.030; median PFS, 10.5 vs 6.7 months, P = 0.008). Furthermore, the treatment modality was an independent prognostic factor for OS (hazard ratio [HR]: 0.449, 95% confidence interval [CI]: 0.240-0.840, P = 0.012) and PFS (HR: 0.406, 95% CI: 0.231-0.713, P = 0.002) according to the multivariate cox regression analysis. A greater ORR was also observed in the triple therapy group (ORR: 56.7% vs 32.4%, P = 0.035). No significant difference was observed in DCR between the two groups (83.7% vs 72.9%, P = 0.259). CONCLUSION: The triple therapy was superior to the monotherapy regarding OS, PFS, and ORR of advanced HCC patients.
