Hepatocellular carcinoma in cirrhotic liver in Trieste.
One hundred consecutive cases of hepatocellular carcinoma (HCC) in cirrhosis observed at autopsy were studied and their pathological aspects were compared with those reported in the literature. The results, which are representative of HCC epidemiology in a geographical area where cirrhosis is mostly due to alcohol abuse, show that similarities in the architectural pattern of HCC and weight of the liver exist between our material and samples with different aetiology and epidemiology. A relationship between the histological grade of HCC and its propensity to metastasize was demonstrated. The reported better prognosis of clear cells per se could not be confirmed, although clear cell HCC occurred exclusively in grade 2. It was also demonstrated that the relationship between grading and staging was strongly influenced by the association of HCC with cirrhosis, which is a fact that is usually overlooked by the common staging (and grading) methods.
