Abstract

<abstract> <title> <x xml:space="preserve">Abstract</x> </title> <sec> <title>Objective:</title> <p>To compare the prognostic factors and outcomes after hepatic resection among patients with hepatitis B virus (HBV)-positive, hepatitis C virus (HCV)-positive, and negative for hepatitis B surface antigen and hepatitis C antibody, so-called "NBNC"-hepatocellular carcinoma (HCC) using the data from a nationwide survey.</p> </sec> <sec> <title>Background:</title> <p>The incidence of NBNC-HCC is rapidly increasing in Japan.</p> </sec> <sec> <title>Methods:</title> <p>A total of 11, 950 patients with HBV-HCC (n = 2194), HCV-HCC (n = 7018), or NBNC-HCC (n = 2738) who underwent a curative hepatic resection were enrolled in this study. The clinicopathological features were compared among the groups. The significant prognostic variables determined by univariate analysis were subjected to a multivariate analysis using a Cox proportional hazard regression model.</p> </sec> <sec> <title>Results:</title> <p>Liver function in the HCV-HCC group was significantly worse than that in the HBV-HCC and NBNC-HCC groups. The NBNC-HCC group had significantly more advanced HCC than the HCV-HCC group. The 5-year overall survival rates after hepatectomy in the HBV-HCC, HCV-HCC, and NBNC-HCC groups were 65%, 59%, and 68%, respectively. The 5-year recurrence-free survival (RFS) rates in these 3 groups were 41%, 31%, and 47%, respectively. Stratifying the RFS rates according to the TNM stage showed that the NBNC-HCC group had a significantly better prognosis than the HBV-HCC group in stages II, III, and IVA, and a significantly better prognosis than the HCV-HCC group in stages I and II. Multivariate analysis revealed a significantly better RFS rate in the NBNC-HCC group.</p> </sec> <sec> <title>Conclusions:</title> <p>The findings of this nationwide survey indicated that patients with NBNC-HCC had a significantly lower risk of HCC recurrence than those with HBV-HCC and HCV-HCC.</p> </sec> </abstract>
