Highly enhanced fucosylation of serum glycoproteins in patients with hepatocellular carcinoma

Abstract

There was a highly significant correlation between LCA-reactive species by CIAE and pyridyl-amino-fucosylated biantennary sugar chain by HPLC in both AAT and TF. Lens culinaris agglutinin-reactive species of AFP, AAT and TF in HCC were significantly higher than those in liver cirrhosis. A highly statistically significant positive correlation of fucosylated glycans was observed between AAT and TF in both HCC and liver cirrhosis, but not between AFP and AAT or between AFP and TF. Accordingly, the present results indicate that highly enhanced fucosylation of serum glycoproteins was found in HCC compared with liver cirrhosis and that the combination of measurements of fucosylated AFP with AAT or TF were useful for the diagnosis of HCC.
