Relation of hemochromatosis with hepatocellular carcinoma: epidemiology, natural history, pathophysiology, screening, treatment, and prevention.

HH is a common inherited disorder of iron metabolism affecting about 1 out of 250 individuals of Northern European decent. Many of these patients do not have evident phenotypic expression and do not develop significant iron loading. Some patients, however, develop progressive iron overload and cirrhosis. These individuals are at risk of developing HCC. Cirrhotics with hemochromatosis should undergo regular screening for HCC. If HCC is identified early, treatment with either resection or liver transplantation is optimal. Palliative measures, including ablative therapy and chemoembolization, can be used. With increasing clinical recognition,hemochromatosis should be diagnosed earlier and progression to cirrhosis and HCC should be minimized.
