Abstract
In order to study clinicopathologic features of hepatocellular carcinoma (HCC) and their relation to metastatic growth, all autopsied cases with confirmed HCC (n = 490) from a period with a high autopsy frequency in a well-defined population were analyzed. Cirrhosis, usually of micronodular type, was found in 72%. The gross appearance of the tumour was predominantly massive (46%) or multinodular (42%). The tumour involved both liver lobes in 72% or the right lobe alone in 20%. Histologically, trabecular growth (79%) and grade II of differentiation (52%) prevailed. Vascular invasion was noted in 56%, whereas involvement of the biliary tract was unusual (4%). Metastases especially involved lymph nodes (42%), lungs (18%) and skeleton (17%). Increased weight of the liver, multinodular appearance, involvement of both liver lobes, low grade of differentiation and vascular invasion were significantly associated with presence of metastases.
