Abstract

Iron overload has been shown to impair the immune response of the liver, and induce hepatic fibrosis and cirrhosis. Opinions differ concerning the relative risk of developing hepatocellular carcinoma (HCC) in siderotic patients as compared with patients with hepatic fibrosis and cirrhosis and the possible mechanism of liver carcinogenesis in genetic hemochromatosis is still unknown. The purpose of this study is to assess hepatic iron overload, fibrosis and cirrhosis in liver tissue adjacent to hepatocellular carcinoma and in liver tissue of controls in population at risk for hepatocellular carcinoma. Liver tissue was available for examination in 147 biopsies with HCC collected in South Africa. As controls we used liver samples from 211 age and sex matched Africans who died in accidents. Tissue samples were processed routinely, stained with H and E, Sweet's reticulin, Masson's trichrome for fibrous tissue, Prussian blue for iron stain and immunohistochemically for HBsAg. Iron content was assessed with the method described by Brissot. Iron overload was detected in 42.1% of cancerous livers and in 43.7% of livers from controls. The presence of siderosis and iron content gradually increased with the age of studied similarly in case...Continue Reading
