Background/Aims: Because hepatitis B virus (HBV) replication has been known to play an important role in cancer recurrence after curative treatment of HBV-related hepatocellular carcinoma (HCC), we examined whether treatment based on nucleos(t)ide analogues (NAs) might decrease the recurrence rate and improve patient survival.
Methods: The retrospective cohort study enrolled 73 patients with chronic hepatitis B who were treated with transarterial chemoembolization (TACE) and radiofrequency ablation (RFA) with curative intent for HCC. Among those, 30 and 43 patients were treated with tenofovir disoproxil fumarate (TDF) and entecavir (ETV), respectively.
Results: Of the 73 patients, 51 experienced HCC recurrence, and 14 patients were dead during a follow-up of 73±34 months. Multivariate analyses showed that tumor size (hazard ratio [HR], 1.590; 95% confidence-interval [CI], 1.106-2.285; P=0.012) and Child-Pugh class B (vs. class A/non cirrhosis; HR, 5.794; 95% CI, 2.311-14.523; P=0.001) was significantly associated with HCC recurrence, and Child-Pugh class B (HR, 7.357; 95% CI, 2.100-25.777; P=0.002) was an independent unfavorable prognostic factor for survival. During NAs therapy, TDF was superior to ETV for complete viral response at 1 year after the date of combination of TACE and RFA (P=0.016). However, the risks of HCC recurrence and survival were not significantly different between those treated with TDF versus ETV.
Conclusions: TDF was superior to ETV for achieving complete viral response. However, the recurrence and mortality after TACE and RFA for HBV-related HCC were not significantly different between patients treated with TDF versus ETV.
