Objective: Transarterial chemoembolization (TACE) is a common therapy for hepatocellular carcinoma (HCC), while TACE-induced tumor angiogenesis would increase progression and metastasis risk. Besides, apatinib possesses the capability of inhibiting tumor angiogenesis. Thus, this study aimed to explore the efficacy and safety of TACE plus apatinib compared to TACE alone in HCC patients.
Methods: Ninety-six intermediate-advanced HCC patients were retrospectively enrolled and classified into TACE plus apatinib group (N = 45) and TACE group (N = 51) based on the treatment.
Results: Objective response rate (68.9% vs. 47.1%) was increased in TACE plus apatinib group than in TACE group (P = 0.031). However, no difference was found in disease-control rate between groups (95.6% vs. 86.3%) (P = 0.167). Progression-free survival (PFS) (median PFS (95% confidence interval (CI)): 20.0 (13.2-26.8) vs. 14.0 (8.3-19.7) months) was enhanced in TACE plus apatinib group compared with TACE group (P = 0.030), while no difference was found in overall survival between groups (P = 0.060). Additionally, multivariate Cox's analysis presented that TACE plus apatinib (vs. TACE alone) independently associated with prolonged PFS (P = 0.043, hazard ratio = 0.617). Regarding safety profile, no difference in liver function indexes (albumin, total bilirubin, alanine aminotransferase and aspartate aminotransferase) was found after treatment between two groups; meanwhile, only the incidence of hand-foot skin reaction (24.4% vs. 7.8%) was higher in TACE plus apatinib group compared to TACE group (P = 0.025), while no difference was found in other adverse events between two groups (all P > 0.05).
Conclusion: TACE plus apatinib illustrates a superior efficacy with tolerable safety than TACE alone in intermediate-advanced HCC patients.
