Abstract

To discuss exhanstively: complex molecular and cellular mechanism in Hepatocellular Carcinoma (HCC); effect of chronic inflammation and cirrhosis, accompained by regenerative process, on the development of HCC; genetic instability of liver cells of regenerating nodules; the relative role of hepatitis C virus (HCV) and hepatitis B virus (HBV) in hepatocarcinogenesis; tumorigenicity of aflatoxin B1 (AFB1); gene expression profiles in HCC; liver tumors and host defense; future perspectives of HCC treatment. We reviewed the most important studies on HCV. HCC is an aggressive malignancy with poor prognosis and is one of the most common tumor in the world. In the majority of cases, HCC is found in conjunction with cirrhosis of the liver. Chronic inflammation and cirrhosis, accompagnied by regenerative process, function as a tumor promoter, providing a common pathway from chronic HBV or HCV infection to HCC. The direct etiologic role of HBV and HCV for HCC is obscure. Tumor progression may be brought about in HCC by mutation of the p53 tumor suppressor gene. The prevalences of p53 mutations is similar in HBV-associated and HCV-associated HCCs. Another mechanisms of host defense are the production of transforming growth factor beta1 (T...Continue Reading
