Transarterial chemoembolization (TACE) plus apatinib-combined therapy versus TACE alone in the treatment of intermediate to advanced hepatocellular carcinoma patients: A real-world study

Abstract

Apatinib exhibits the synergistic effect with transarterial chemoembolization (TACE) though inhibiting the neoangiogenetic reaction caused by TACE. In this real-world study, we aimed to evaluate the efficacy and safety of TACE plus apatinib-combined therapy (ACT) in intermediate to advanced hepatocellular carcinoma (HCC) patients. Data from 168 intermediate to advanced HCC patients who received TACE alone (N = 49) or TACE plus ACT (N = 119) were extracted. Besides, ACT was defined as apatinib with or without other therapy, such as arsenic trioxide, microwave ablation and radioactive seed implantation. In TACE plus ACT group, the median overall survival (OS) was 30 months (95% confidence interval (CI): 24-40 months) with 1-year, 3-year and 5-year OS rate of 84.0%, 41.2% and 21.5%, respectively. While in TACE group, the median OS was only 14 months (95%CI: 11-17 months) with 1-year, 3-year and 5-year OS rate of 55.1%, 18.4% and 16.1%, separately. By comparation, the OS was prolonged in TACE plus ACT group compared with TACE group (P<0.001). After adjusted by multivariate Cox's regression analysis, TACE plus ACT (vs. TACE) independently related to the longer OS (hazard ratio: 0.504, P = 0.001). In TACE plus ACT group, the most frequent adverse events included hand-foot syndrome (95.8%), hypertension (95.8%), fatigue (90.8%), albuminuria (85.7%), anorexia (79.0%), diarrhea (66.4%), myelosuppression (58.8%), nausea/vomiting (49.6%) and abdominal pain (39.5%), besides, no grade 4 adverse events and treatment-related death occurred. TACE plus ACT is a promising treatment choice for the intermediate to advanced HCC patients.
