  • Title: Development of a novel score for early detection of hepatocellular carcinoma among high-risk hepatitis C virus patients.
    Author: El-mezayen HA, Darwish H.
    Journal: Tumour Biol; 2014 Jul; 35(7):6501-9. PubMed ID: 24687551.
    Abstract:
    Hepatocellular carcinoma (HCC) is often diagnosed at advanced stage where effective therapies are lacking. Identification of new scoring system is needed to discriminate HCC patients from those with chronic liver disease. Based on the link between vascular endothelial growth factor (VEGF) and HCC progression, we aimed to develop a novel score based on combination of VEGF and routine laboratory tests for early prediction of HCC. VEGF was assayed for HCC group (123), liver cirrhosis group (210), and control group (50) by enzyme-linked immunosorbent assay (ELISA). Data from all groups were retrospectively analyzed including α-fetoprotein (AFP), international normalized ratio (INR), albumin and platelet count, transaminases, and age. Areas under receiving operating curve (ROC) were used to develop the score. A novel index named hepatocellular carcinoma-vascular endothelial growth factor score (HCC-VEGF score) = 1.26 (numerical constant + 0.05 × AFP (U l(-1)) + 0.038 × VEGF (ng ml(-1)) + 0.004 × INR - 1.02 × albumin (g l(-1)) - 0.002 × platelet count × 10(9) l- (1) was developed. HCC-VEGF score produce area under ROC curve of 0.98 for discriminating HCC patients from liver cirrhosis with sensitivity of 91 % and specificity of 82 % at cutoff 4.4 (i.e., less than 4.4 considered cirrhosis and greater than 4.4 considered HCC). Hepatocellular carcinoma-VEGF score could replace AFP in HCC screening and follow up of cirrhotic patients.
