METHODS： The mean follow-up time was 83.6 ± 39.6 mo. Alpha-fetoprotein test and abdominal ultrasound were used for cancer surveillance. Hepatitis B basal core promoter mutants, precore mutants, genotypes, hepatitis B viral DNA （HBV DNA） level and hepatitis B e antigen （HBeAg） were measured. Univariate analysis and logistic regression were used to assess odds ratios for viral factors related to liver deaths and hepatocellular carcinoma development. RESULTS： During follow-up, 38 patients had liver deaths not related to hepatocellular carcinoma. On multivariate analysis, older age [odds ratio： 95.74 （12.13-891.31）, P 〈 0.0001], male sex [odds ratio： 7.61 （2.20-47.95）; P = 0.006], and higher Iogzo HBV DNA [odds ratio： 4.69 （1.16-20.43）; P 〈 0.0001] were independently predictive for these liver related deaths. Also, 31 patients developed hepatocellular carcinoma. Multivariate analysis showed that older age [odds ratio： 26.51 （2.36-381.47）; P = 0.007], presence of precore mutants [odds ratio： 4.23 （1.53-19.58）, P = 0.02] and presence of basal core promoter mutants [odds ratio： 2.93 （1.24-7.57）; P = 0.02] were independent predictors for progression to hepatocellular carcinoma. CONCLUSION： Our results show that high levels of baseline serum HBV DNA are associated with non- hepatocellular carcinoma-related deaths of liver failure, while genetic mutations in the basal core promoter and precore regions are predictive for development of hepatocellular carcinoma.展开更多
