Serum Squamous Cell Carcinoma Antigen Level in Cirrhotic Chronic Hepatitis C Patients With and Without Hepatocellular Carcinoma

This study will be carried out on 500 personnel divided into five groups : Group A: 100 cases of hepatocellular carcinoma without interventions. Group B: same 100 cases of group A before and 3 months after successful interventions.Group C: 100 cases of established cirrhosis. Group D: 100 cases with chronic hepatitis C virus infection without established cirrhosis. Group E: 100 healthy individuals as controls. Methods: Sera from selected patients and controls have been used for estimation of SCC-Ag using CanAg SCC EIA. Results: high significant increase in serum SCCA level in patients with HCC (groupA and groupB) when compared to cirrhotic, chronic HCV and control groups (P < 0.001). Positive significant correlation was found between AFP and serum SCCA level .The best cut-off value to differentiate HCC patients from cirrhotic patients was 3.2 ng/ml for SCCA yielded with 80% sensitivity and 90% specificity. When combined sensitivity of both markers was calculated in our study at the best-chosen cutoff values (SCCA 3.2 ng/ml and AFP 200 ng/ml) sensitivity improved to 93%. Conclusion: Combined SCCA and AFP can be used as in diagnosis of HCC and follow up 3 months after therapeutic intervention.
