BACKGROUND: The aim of this study was to elucidate the usefulness of measuring the fucosylation index (FI) of alpha-fetoprotein (AFP) before the initiation of therapy as a new prognostic indicator for patients with hepatocellular carcinoma (HCC). METHODS: One hundred twelve patients with HCC who underwent transcatheter arterial embolization, chemoembolization, and/or percutaneous ethanol injection were examined in the current study. FI was determined by crossed immunoaffino-electrophoresis in the presence of Lens culinaris agglutinin. RESULTS: When the tentative discriminating value of FI was set at 18%, the mean survival rate for the group whose FI was higher than 18% was significantly lower than that for the group whose FI was equal to or less than 18%, according to the generalized Wilcoxon test (P = 0.0117) and the log rank test (P = 0.0183). The survival rate for HCC patients with AFP concentrations of more than 200 ng/mL was also significantly lower than that for patients with AFP in the range of 21-200 ng/mL, according to the generalized Wilcoxon test (P = 0.0017) and the log rank test (P = 0.0018). When FI was combined with AFP concentration, a highly significant difference was observed between the group with FI >18% and AFP >200 ng/mL and another group with FI < or =18% and AFP < or =200 ng/mL, as determined by the generalized Wilcoxon test (P < 0.0001) and the log rank test (P = 0.0003). An analysis of multiple covariates in the prognostic factors with the Cox proportional hazards model showed that FI was one of the independent prognostic factors. CONCLUSIONS: The current study indicates that measuring FI from sera before the initiation of treatment serves as a new prognostic factor and may improve prognostic estimates and appraisal of therapeutic outcomes for patients with HCC.
