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.
