title: [Subject diagnostic value of detecting a1pha-fetoprotein variants with a new microspincolumn method in hepatocellular carcinoma].
abstract: OBJECTIVE
  To evaluate the usefulness of new microspincolumn method for the measurement of a1pha-fetoprotein variant AFP-L3 in differentiation of benign and malignant liver disease and the warming for liver cancer.
  
  
  METHODS
  AFP-L3 was isolated by using microspincolumn coupled with lens culinaris agglutinin (LCA), AFP and AFP-L3 were determined with chemiluminescent immunoassay, the proportion of AFP-L3 levels AFP-L3(%) were calculated, and the relationship between the elevated AFP-L3(%) levels and benign and malignant liver disease was analyzed.
  
  
  RESULTS
  The levels of AFP-L3(%) in serum of patients with hepatocellular carcinoma was significantly higher than those in the patients with other liver diseases (P < 0.001). Taking AFP-L3(%) >or= 10% as the diagnostic criteria, the sensitivity for diagnosis of liver cancer was 90.9%.
  
  
  CONCLUSIONS
  Detection of AFP-L3 seemed to be of clinical value in diagnosis and differential diagnosis of hepatocellular carcinoma; it may be especially important for identifying patients with hepatocellular carcinoma whose a1pha-fetoprotein level is low.
