Background The treatment of hepatocellular carcinoma (HCC) patients with portal vein tumor thrombus (PVTT) remains controversial due to the limited effect of sorafenib. The aim of the study was to investigate whether apatinib could improve the efficacy of transarterial chemoembolization (TACE) for patients with HCC complicated by PVTT. Methods The study included 109 patients with HCC and PVTT who received TACE combined with apatinib (TACE + apatinib) (53 patients) or TACE alone (56 patients) between June 2015 and January 2019. Propensity score matching (PSM) analysis was used to reduce the potential selection bias. Overall survival time (OS) and time to progression (TTP) were used to evaluate the efficacy of TACE + apatinib and TACE alone. Results Before PSM, TACE + apatinib significantly improved median TTP (7.0 vs. 3.0 months, P < 0.001) and median OS (15.0 vs. 7.0 months, P < 0.001) when compared with TACE alone. After PSM, the median TTP was significantly longer in the TACE + apatinib group, 6.0 months, than in the TACE alone group, 3.0 months (P < 0.001), and the median OS was significantly longer in the TACE + apatinib group, 14.0 months, than in the TACE alone group, 7.0 months (P < 0.001). Subgroup analysis revealed that, except for patients with Child–Pugh class B, the patients with or without extrahepatic metastases and with Child–Pugh class A had longer TTP and OS after the combined TACE + apatinib treatment than after TACE alone. Conclusion The combination of TACE + apatinib might be an effective and safe treatment for HCC patients with PVTT.
