A Diagnostic Value of Serum Level Cyclase-Associated Plasma Protein 2 Versus Alpha Fetoproteins as a novel Biomarker for Detection of Hepato-Cellular Carcinoma in Egyptian Patients with Liver Cirrhosis
Abstract Background HCC is the third deadliest and fifth most common cancer worldwide, despite the widespread use of surveillance programs in at risk populations, more than half of HCC cases are diagnosed late, and curative therapies such as surgical resection, radiofrequency ablation or TACE are possible in less than 30% of patients. Objective To assess the value of plasma cyclase-associated protein 2 level in diagnosis of hepatocellular carcinoma among the Egyptian patients with chronic hepatitis c virus. Patients and Methods This study has been carried out in the department of Internal Medicine and Gastroenterology in Ain Shams University Hospitals and Manshiet El-Bakry general hospital, Department of Gastrohepatology. This study evaluate the significance of Plasma CAP2 level as a new diagnostic marker for HCC patients with post hepatitis C liver cirrhosis where (80) persons, divided into three groups; Group A included (30) patients with post hepatitis C liver cirrhosis without HCC, Group B included (40) patients with post hepatitis C liver cirrhosis and HCC, and Group C included (10) healthy subjects as a control group. Results In this study CAP2 was significantly higher in HCC group than in cirrhotic and control groups (p < 0.001) with mean levels (30.7±12.4), (14.4±7.6), and (6.9±4.3) ng/ml respectively although in HCC patients with negative or low AFP levels. This finding could imply the role of CAP2 in diagnosing early and AFP negative HCC patients. Conclusion CAP2 is significantly elevated in HCC group than in cirrhotic and control groups with better sensitivity and specificity than AFP at cut off values ≥15.9 ng/ml and ≥53.2 ng/ml respectively. Such results support using of CAP2 as a better diagnostic marker for HCC. AFP and CAP-2 were higher in multiple lesions than in single lesions, but the differences were significant only in CAP-2 with ≥27.3 ng/ml in differentiating multiple from solitary lesions Considering the HCC if both of them were positive decreased sensitivity but had perfect specificity.
