Transarterial chemoembolization (TACE) combined with apatinib has been used for advanced hepatocellular carcinoma (HCC), and the efficacy is good. The study was conducted to compare the efficacy and safety of drug-eluting bead TACE plus apatinib (D-TACE-A) with conventional TACE plus apatinib (C-TACE-A) in the treatment of HCC with portal vein tumor thrombus (PVTT). A total of 130 continuous patients who received D-TACE-A or C-TACE-A were included in the study from January 2017 to June 2020. Propensity score matching (PSM) was used to reduce potential selection bias. Before PSM, the median overall survival (mOS) (14 months) and median progression-free survival (mPFS) (7 months) in the C-TACE-A group were longer than the mOS (9 months; P = 0.001) and mPFS (4 months; P = 0.001) in the D-TACE-A group. After PSM, the mOS (14 months vs 9 months; P = 0.039) and mPFS (7 months vs 5 months; P = 0.009) in the C-TACE-A group were longer than those in the D-TACE-A group. In the multivariate regression analysis, C-TACE-A reduced the mortality rate and tumor progression rate compared with D-TACE-A. For the subgroup analysis, patients with VP1–2, without extrahepatic metastases, and with multiple TACE sessions who received C-TACE-A had a lower death risk and tumor progression risk than patients who received D-TACE-A. Before PSM, there was no statistically significant difference in any grade or grade III/IV adverse events (all P > 0.05). C-TACE-A could prolong mOS and mPFS in patients with PVTT, especially for patients with VP1–2 stage PVTT, no extrahepatic tumor metastases, and multiple TACE sessions.
