Evaluation of serum protein markers in diagnosis of hepatocellular carcinoma and carcinogenesis risk assessment in chronic liver disease patients

Abstract

Objective: To assess the diagnostic value of the protein markers in both cirrhotic patients on top of hepatitis C virus (HCV) and in hepatocellular carcinoma (HCC) patients on top of HCV in comparison to normal controls. Methods: A total number of 100 subjects including HCC, cirrhotic patients on top of HCV and normal controls were subjected to serum protein markers analysis for alpha-fetoprotein, apolipoprotein A1, apolipoprotein A2, insulin like growth factor 1 and insulin like growth factor 1 receptor by western blotting technique. Results: It was found that alpha-fetoprotein alone could not be used as a screening test while apolipoprotein A2 as a serum marker could be used as a non invasive screening test to differentiate a case of HCC from cirrhotic HCV patient. The all four markers were able to discriminate normal persons from HCC and cirrhotic HCV patients effectively. Conclusions: We concluded that proteomics analysis being non invasive, rapid and sensitive is a novel gate that can serve in early diagnosis and screening of HCC and cirrhotic HCV patients.
