Pretreatment AKR1B10 expression in the liver was immunohistochemically assessed and quantified as a percentage of positive staining area by using image-analysis software. A multivariate Cox analysis was used to estimate the hazard ratios(HRs) of AKR1B10 expression for hepatocellular carcinoma(HCC) development after achieving SVR. The cumulative incidences of HCC development were evaluated using Kaplan-Meier analysis and the log-rank test.RESULTS Of the 303 chronic hepatitis C patients,153(50.5%) showed scarce hepatic AKR1B10 expression,quantified as 0%,which was similar to the expression in control normal liver tissues. However,the remaining 150 patients(49.5%) exhibited various degrees of AKR1B10 expression in the liver,with a maximal AKR1B10 expression of 73%. During the median follow-up time of 3.6 years(range 1.0-10.0 years),8/303 patients developed HCC. Multivariate analysis revealed that only high AKR1B10 expression(≥ 8%) was an independent risk factor for HCC development(HR = 15.4,95%CI: 1. 8- 1 3 2. 5,P = 0. 0 1 2). T h e 5- y e a r c u m u l a t i v e incidences of HCC development were 13.7% and 0.5% in patients with high and low AKR1B10 expression,respectively(P < 0.001). During the follow-up period after viral eradication,patients expressing high levels of AKR1B10 expressed markedly higher levels of alanine aminotransferase and α-fetoprotein than did patients exhibiting low AKR1B10 expression.CONCLUSION Chronic hepatitis C patients expressing high levels of hepatic AKR1B10 had an increased risk of HCC development even after SVR.展开更多
