Pathogenesis and screening for hepatocellular carcinoma.
Hepatocellular carcinoma is an increasingly common clinical problem. Investigators have begun to understand aspects of the pathogenesis of the tumor, mainly from a morphologic point of view. Preneoplastic lesions and early cancer may be difficult to distinguish radiologically. Nonetheless, programs for surveillance of liver cancer have been developed. Little uniformity exists in methods of surveillance, and even less in methods of investigation and follow-up after an abnormal result is obtained. This article attempts to bring some rigor to the understanding of hepatocellular carcinoma.
