Hepatocarcinogenesis Is Associated with Serum Albumin Levels after Sustained Virological Responses with Interferon-Based Therapy in Patients with Hepatitis C

Objective: It is a generally accepted fact that eradication of hepatitis virus C inhibits the subsequent development of hepatocellular carcinoma (HCC). On the contrary, a significant population of patients developed HCC despite sustained virological responses (SVRs) to interferon (IFN) therapy. Methods: A total of 415 patients with chronic hepatitis C, who were treated at our hospital between 2004 and 2014, were enrolled for this study. We examined the risk factors for HCC development after IFN therapy. Results: After analyzing various clinical parameters, it was concluded that a serum albumin (ALB) level <4.0 g/dL and the presence or absence of SVR achievement were risk factors for the development of HCC. When analyzing pre- and posttreatment factors, only a serum ALB level <4.0 g/dL was considered a significant risk factor. The presence or absence of liver fibrosis progression was not identified as a risk factor. Conclusions: In patients with a serum ALB level <4.0 g/dL before IFN therapy, hepatic carcinogenesis after SVR achievement need to be considered. Furthermore, the serum ALB level may be more useful than the degree of fibrosis for the prediction of HCC after SVR in chronic hepatitis C.
