[Diagnosis of hepatocellular carcinoma].

Hepatocellular carcinoma (HCC) is a frequent complication of chronic liver disease. The major causes of chronic liver diseases are hepatitis B virus (HBV) or hepatitis C virus (HCV) infection, as well as chronic alcohol misuse. The clinical presentations of HCC patients are unspecific, with signs and symptoms of chronic liver disease. Early diagnosis of HCC in an asymptomatic and potentially curable stage is of highest priority. The present strategy for the detection of early HCC in patients with chronic liver disease is 6-monthly determination of alpha-fetoprotein (AFP) and ultrasound study of the liver. If these are abnormal, further diagnostic steps include computer tomography, magnetic resonance tomography, lipiodol-angiography and histopathology. By this sequential diagnostic strategy it should be possible to identify HCC in patients with chronic liver disease at an early and potentially curable stage.
