Flow cytometric DNA analysis was performed in 50 paraffin-embedded specimens of clinical hepatocellular carcinoma (HCC) after hepatic resections. The DNA distribution pattern was classified in two types, diploid and aneuploid, according to the degree of dispersion on the DNA histogram. The major DNA pattern of HCC in this report proved to be aneuploid (78%), although 22% of tumors revealed a diploid pattern. The serum alpha-fetoprotein level exceeded 40 ng/ml in 86.1% of the aneuploid tumors and in 13.9% of the diploid tumors (p less than 0.05). We found no correlation between DNA distribution and hepatitis B surface antigen positivity, the presence of liver cirrhosis or tumor size. Additionally we noted no significant correlation between the DNA pattern and survival rates in patients with HCC who underwent hepatic resection.
