Abstract
BACKGROUND/AIM:
We aimed to identify the incidence rate of hepatocellular carcinoma (HCC) in chronic hepatitis B (CHB) patients treated with entecavir or tenofovir in South Korea, and to identify predictors of HCC development in these patients.
METHODS:
Between January, 2007 and December, 2015, 582 CHB patients initially received entecavir (n=406, 69.8%) or tenofovir (n=176, 30.2%) for CHB.
RESULTS:
During a median follow-up of 57.1 months, HCC developed in 38 (6.5%) of the 582 patients, regardless of antiviral agent type. Entecavir and tenofovir treated patients had similar HCC development rates (p=0.471). For the 582 patients, 2-, 4- and 6-year cumulative HCC development rates were 2.6%, 4.4 %, and 8.3%, respectively, and the 2-, 4-, and 6-year cumulative HCC development rates of patients with liver cirrhosis were significantly greater than those of patients without liver cirrhosis (6.2%, 9.8%, and 18.4% vs. 0.3%, 1.1%, and 2.2%, respectively, p<0.001). Older (≥60 years) patients regardless of the presence of cirrhosis and cirrhotic patients with age of ≥40 years showed significantly higher risk of HCC development compared to others (p<0.05, respectively). Multivariate analysis showed that an older age (≥50 years; hazard ratio [HR] 5.02, p=0.009), and the presence of cirrhosis (HR 4.95, p=0.002) independently predicted HCC development.
CONCLUSIONS:
The 6-year cumulative HCC development rate was 6.5% in CHB patients treated with entecavir or tenofovir. An age of ≥ 50 and liver cirrhosis were found to predict HCC development in these patients.
