In 645 patients, HBsAg and HBV DNA showed a significant correlation (r=0.693, P<0.001), and this was also observed in the IT, EPH and IC groups (r=0.664, r=0.541, r=0.505, respectively, all P<0.001), but not in the ENH group (r=0.093, P=0.321).
Hepatocellular carcinoma (HCC) is widely known to develop more frequently in cirrhotic patients with a high expression of Hepatitis B virus X protein (HBx), which is controlled by the enhancer 1 (Enh1)/X-promoter.
Patients were categorized according to the phase of HBV-infection: HBeAg(+) immune tolerance phase (IT, n=30), immune clearance phase (IC, n=48), HBeAg(-) low-replicative phase (LR, n=68), HBeAg(-) hepatitis (ENH, n=68), and acute hepatitis B (n=12).
