Predictive value of liver cell dysplasia for development of hepatocellular carcinoma in patients with chronic hepatitis B

Abstract

GOALS: We aimed to determine whether the presence of large liver cell dysplasia (LLCD) and/or small LCD (SLCD) in chronic hepatitis B is a risk factor for hepatocellular carcinoma (HCC) development.

BACKGROUND: A close relationship between LLCD/SLCD and hepatitis B virus has been observed and SLCD has been proposed to be a putative precursor of HCC, whereas the significance of LLCD is still controversial.

STUDY: One hundred eighty-one patients with chronic hepatitis B who underwent needle liver biopsy were evaluated for the presence of LLCD/SLCD. The predictive value of LLCD/SLCD for HCC development was assessed.

RESULTS: LLCD and SLCD were present at initial biopsy in 82 (45%) and 17 (9%) patients, respectively. During the mean follow-up of 115+/-48 months, 19 (10%) cases were diagnosed of HCC, of which 13 (76%) and 3 (17%) cases had demonstrated LLCD and SLCD, respectively, at initial evaluation. The patients with LLCD showed a significantly higher cumulative probability of HCC development than those without LLCD (P=0.016). The risk of HCC development in the presence of LLCD was approximately 3-fold, with positive and negative predictive values of 15.9% and 94.9%, respectively. The patients with SLCD showed no significant difference in cumulative probability of HCC development compared with those without (P>0.05).

CONCLUSIONS: LLCD in chronic hepatitis B is considered to be one of the risk factors for HCC development and its presence may help to identify a high-risk subgroup of patients requiring more intensive screening for HCC.
