[The significance of the determination of AFP-isoform in the early diagnosis of hepatocellular carcinoma]

Abstract

To evaluate the significance of the determination of the AFP-isoform in the early diagnosis of hepatocellular carcinoma (HCC), the AFP-isoform was determined in 48 patients with HCC and in 53 patients with liver cirrhosis, using the lectin electrophoresis of AFP by antibody-affinity blotting technique. 1. The HCC-type AFP-isoform was detected in 44 of the 48 patients with HCC, 2. In about 30% of the patients with HCC, the HCC-type AFP-isoform appeared 3-10 months before the graphic diagnosis of HCC, 3. In about 60% of the patients with liver cirrhosis found to have the HCC-type AFP-isoform, HCC developed within one year. Thus, the serial determination of the AFP-isoform in patients with liver cirrhosis was considered very useful for the early diagnosis of HCC.
