Hepatitis B e antigen predicts delayed reduction of HBV DNA without viral breakthrough with adefovir dipivoxil and lamivudine: a 5-year study of patients with hepatitis B with lamivudine resistance.

To clarify the factors associated with delayed reduction of HBV DNA during combination treatment with adefovir dipivoxil (ADV) and lamivudine (LAM) for patients with LAM-resistant hepatitis B virus (HBV), factors including patient characteristics, viral mutations, and drug metabolism were investigated during a 5-year observation period. Delayed reduction of HBV DNA was defined as delayed viral response of detectable HBV DNA after 3 years of combination therapy. Of 67 consecutive patients, 47 attained undetectable HBV DNA after 3 years of combination therapy, and the mean therapeutic duration was 5 years (range: 3.

Prognostic model for hepatocellular carcinoma with time-dependent factors.

The purpose of this study was to build a prognostic model of hepatocellular carcinoma (HCC) using time-dependent covariates to re-evaluate the prognosis at any stage of the disease. The subjects were consecutive HCC patients who were treated at our institute between 1995 and 2007. We constructed time-fixed and time-dependent prognostic models with a training group (n=336) and compared the prognostic abilities between conventional Cancer of the Liver Italian Program (CLIP) scores, Japan Integrated Staging (JIS) scores, an Okuda classification, and our prognostic models in the testing group (n=227) with the c-index.

Time-dependent analysis of predisposing factors for the recurrence of hepatocellular carcinoma.

Background/aim: There are many reports dealing with the risk factors for hepatocellular carcinoma (HCC) recurrence. However, in most of these reported studies, factors were analysed only at the initial treatment stage, and the predisposing factors for the recurrence during follow-up have not been well studied. The aim of this study is to evaluate the predisposing factors after treatments.
