BACKGROUND AND AIM: Early detection of hepatocellular carcinoma (HCC) enhances effective and curative management. New genetic markers with distinct diagnostic ability are required. AIM: determine the expression of GPC3, PEG10, SERPINI1, MK and QP-C in the peripheral blood of HCC patients. METHODS: 74 HCV patients were recruited and divided into three groups; chronic hepatitis (I), liver cirrhosis (II) and HCC (III). Demographics, laboratory and imaging data were collected. Child score and metastatic work up were completed. The expression of the five candidate genes in the peripheral blood was performed by qRT-PCR assay. RESULTS: Groups were gender matched, age in group I was significantly lower than in groups II and III (37.7 vs 50.4 and 55.6, p value <0.005). CHILD score; group II and III A/B/C = (7/5/6) and (20/6/3). AFP was significantly higher in group III than I and II (204 vs 3.9 and 6.9, p < 0.01). In HCC group 69% of the lesions were < 5 cm, and had 1-2 nodules; 14% had metastases. GPC3, PEG10, SERPINI1 and MK mRNA were significantly higher in the HCC group compared to the other groups while QP-C mRNA was higher in chronic hepatitis C group compared to other groups. The gene expression values in HCC patients were independent of the tumor size, AFP levels or extrahepatic metastasis. Combined measurement of the five gene markers showed 100% sensitivity and 33% specificity, 48% PPV and 100% NPV. CONCLUSION: GPC3, PEG10, SERPINI1 and MK are genetic markers that can represent a useful tool for detection of HCC.
