| Outline of Final Research Achievements |
Sustained virological response (SVR) is defined as undetectable serum hepatitis C virus (HCV) RNA after completion of antiviral therapy for chronic HCV infection. We studied resected liver tissues in 53 patients with initial hepatocellular carcinoma (HCC) after achieving SVR. This study found following insights. (1) Hepatic fibrosis that does not decrease sufficiently after achieving SVR may be a risk factor of liver carcinogenesis in the patients after achieving SVR. Sinusoidal capillarization, i.e., CD34 expression in sinusoidal mesenchymal cells, and activation of HSCs, i.e., αSMA expression in sinusoidal mesenchymal cells, may contribute to hepatic fibrosis after achieving SVR. (2) There were 14 patients with previous infection of hepatitis B virus.
