    Abstract:
    BACKGROUND: The objectives were to assess the safety and efficacy of drug-eluting bead transarterial chemoembolization (DEB-TACE) as locoregional therapy (LRT) in hepatocellular carcinoma (HCC) before liver transplantation (LT) beyond Hangzhou criteria (HC) and to analyze the prognostic factors. METHODS: Forty patients with HCC beyond HC who received DEB-TACE only before LT were retrospectively analyzed between January 2017 and December 2022. Data on patient demographics, disease characteristics, treatment response, and adverse events (AE) were collected. Overall survival (OS) and recurrence-free survival (RFS) were evaluated with Kaplan-Meier curves. Univariate and multivariate Cox regression analyses were performed to identify factors independently associated with RFS and OS. RESULTS: All patients successfully underwent LT following DEB-TACE with a mean interval of 2.3 months. The objective response rates (ORRs) for these patients following DEB-TACE was 82.5%. The primary AE was post-embolization syndrome (PES), with affected patients experiencing grades I and II. The median RFS and OS were 12.0 months (95%CI: 0.0-30.1) and 52.0 months (95%CI: 11.8-92.2) over the follow-up period until December 2022. The 2-year RFS and OS rates were 42.5%, and 67.5%. Multivariate analyses revealed Child-Pugh classification (HR = 6.24; 95%CI,1.83-21.24; P = 0.01) and macrovascular invasion (MAV) (HR = 3.89; 95%CI,1.07-14.15; P = 0.04) were both significant independent predictors of OS. CONCLUSIONS: DEB-TACE can serve as a safe and effective LRT in HCC patients beyond HC before LT, and can improve the prognosis of patients, especially without MAV. The higher Child-Pugh classification and MAV are independent prognostic factors after LT.
