Abstract

Objectives: This study aims to compare the safety and effectiveness between transarterial chemoembolization (TACE) with drug-eluting beads (DEB-TACE) and conventional TACE (cTACE) using lipiodol-based regimens in HCC patients with a transjugular intrahepatic portosystemic shunt (TIPS).

Methods: This retrospective study included patients with patent TIPS who underwent TACE from January 2013 to January 2019 that received either DEB-TACE (DEB-TACE group, n = 57) or cTACE (cTACE group, n = 62). The complications, liver toxicity, overall survival (OS), time to progression (TTP), and objective response rate (ORR) were compared between the groups.

Results: Altogether, 119 patients (50 ± 11 years, 107 men) were evaluated. The incidence of adverse events, including abdominal pain within 7 days (45.6% vs 79.0%, p < 0.001) and hepatic failure within 30 days (5.3% vs 19.4%, p = 0.027), were significantly lower in the DEB-TACE group than in the cTACE group. Compared to the cTACE group, the DEB-TACE group also showed mild liver toxicities in terms of increased total bilirubin (8.8% vs 22.6%), alanine aminotransferase (5.3% vs 21.0%), and aspartate aminotransferase (10.5% vs 29.0%) levels. The DEB-TACE group had better ORR than the cTACE group (70.2% vs 50.0%). The median OS and TTP were longer in the DEB-TACE group (11.4 vs 9.1 months, hazard ratio [HR] = 2.46, p < 0.001; 6.9 vs 5.2 months, HR = 1.47, p = 0.045). Multivariable analysis showed that α-fetoprotein levels, Barcelona clinic liver cancer stage, and treatment allocation were independent predictors of OS.

Conclusion: DEB-TACE is safe and effective in HCC patients with a TIPS and is potentially superior to cTACE in terms of complications, liver toxicities, OS, TTP, and ORR.

Key points: • DEB-TACE is safe and effective in HCC patients after a TIPS procedure. • DEB-TACE improves overall survival, objective response rate, and liver toxicities and is non-inferior to cTACE in terms of time to progression. • DEB-TACE might be a potential new therapeutic option for HCC patients with TIPS.
