RT Journal Article SR Electronic T1 Histological characteristics predisposing to development of hepatocellular carcinoma in patients with chronic hepatitis B JF Journal of Clinical Pathology JO J Clin Pathol FD BMJ Publishing Group Ltd and Association of Clinical Pathologists SP 599 OP 604 DO 10.1136/jclinpath-2011-200036 VO 64 IS 7 A1 Sae Hwan Lee A1 Young-Hwa Chung A1 Jeong A Kim A1 Young-Joo Jin A1 Won Hyung Park A1 Jong Gi Choi A1 Danbi Lee A1 Ju Hyun Shim A1 Eunsil Yu A1 Myoung Kuk Jang YR 2011 UL http://jcp.bmj.com/content/64/7/599.abstract AB Aims Longstanding liver inflammation leads to hepatic regeneration and fibrosis, which subsequently progresses to cirrhosis in some patients with chronic hepatitis B virus (HBV) infection. It remains unclear, however, if the histological severity of chronic hepatitis B (CHB) may determine the development of hepatocellular carcinoma (HCC). The aim of this study was to evaluate the effects of necroinflammation and fibrosis at presentation of CHB on the development of HCC.Methods Medical records and radiographs of 796 biopsy-confirmed CHB patients were reviewed retrospectively for a median period of 107 months (6–218) (median age 34 years (18–64), male:female 636:160). Eighty-five per cent (680/796) of patients were treated with antiviral agents such as interferon alpha and/or lamivudine. All the patients were followed at a regular interval of 3–6 months with routine laboratory tests. Abdominal imagings together with serum alpha-fetoprotein were checked every 6–12 months to detect new HCC. Necroinflammation and fibrosis were assessed semiquantitatively. Univariate and multivariate analyses were performed to identify significant risk factors for HCC.Results HCC developed in 3.4% (27/796) of patients during follow-up. The overall cumulative occurrence rates of HCC were 0.5% and 3.5% at 5 and 10 years, respectively. In multivariate analysis, age over 40 years (p<0.001), advanced fibrosis (p=0.006) and severe lobular activity (p=0.038) at presentation were independent risk factors for the development of HCC.Conclusion Advanced fibrosis and severe lobular activity rather than porto–periportal activity on histology at presentation of CHB are independent predisposing risk factors for the development of HCC.
