The studies on early warning of Lens culinaris-reactive alpha-Fetoprotein (AFP-L3) detecting in primary hepatocellular carcinoma / 中华实验和临床病毒学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To explore the significance of Lens culinaris-reactive alpha-Fetoprotein (AFP-L3) detection in primary hepatocellular carcinoma.</p><p><b>METHODS</b>AFP-L3 was isolated by using microspin column coupled with lens culinaris agglutinin (LCA), AFP and AFP-L3 were detected with chemiluminescent immunoassay, the proportion of AFP L3 levels were calculated, and the relationship between the elevated AFP-L3 (%) levels and benign and malignant liver disease was analyzed.</p><p><b>RESULTS</b>There were significant differences in positive rate between the patients of HCC, suspected HCC and other liver disease (81.80%, 73.68%, 11.80%, respectively, P < 0.05). Among the undetermined HCC (suspected HCC, liver disease) patients, 12 out of 21 cases of AFP-13 positive were diagnosed to be HCC within 6 months, and 6 of them were diagnosed to be the single small HCC at the early stage through B-Ultrasonic Diagnosis or CT. Among 62 cases of AFP-L3 negative, 3 cases were diagnosed to be HCC within 6 months and the risk of occurrence of HCC for AFP-L3 positive increased 11.9 times.</p><p><b>CONCLUSION</b>AFP-L3 has no correlation with AFP value, and it can be used as an independent HCC diagnosis factor. The detection of AFP-L3 has a significant implication for the identification of benign or malignant liver disease and the early stage predictive diagnosis of HCC while AFP increases.</p>
