Abstract

Abstract Objectives To compare the efficacy, overall survival (OS) and safety of drug-eluting beads-TACE (DEB-TACE) and C-TACE as initial treatment in advanced hepatocellular carcinoma (HCC) patients with main portal vein tumor thrombus (mPVTT). Methods The medical records of consecutive advanced HCC patients with mPVTT who underwent initial DEB-TACE or C-TACE from September 2015 to October 2021 were retrospectively evaluated. Treatment crossover was allowed in this retrospective research. The adverse events, disease control rate (DCR), time to tumor progression (TTP) and OS of patients who underwent DEB-TACE were compared with those of patients who underwent C-TACE. Results Eighty-three patients were included: 42 patients in DEB-TACE group and 41 patients in C-TACE group. DEB-TACE could be safely performed in HCC patients with mPVTT, and they gained a better DCR than those submitted to the C-TACE (76.2% vs. 53.7%, P = 0.031), which might have resulted in longer TTP (median TTP: 9.0 months vs. 3.0 months, P < 0.001). Furthermore, DEB-TACE showed significant OS benefits compared with C-TACE (median OS: 12.0 months vs. 5.0 months, P < 0.001). DEB-TACE, absence of arterioportal shunts (APS), leisons with capsular non-infiltration were found to be independent prognostic factors for better OS. Furthermore, subgroup analysis proved that patients with good DCR gained longer OS in DEB-TACE group. Conclusions DEB-TACE could be safely performed and improve the DCR of HCC patients with mPVTT, which resulting in longer TTP and OS, compared with C-TACE.
