Role of Serum Glypican-3 in the Diagnosis of Hepatocellular Carcinoma in the Upper Egypt

Background and Aim: Early diagnosis of hepatocellular carcinoma (HCC) is essential for achieving good prognosis. Glypican 3 (GPC3) has been reported to be raised in HCC in comparison with non-neoplastic lesions. This work aimed to study the role of GPC3 in the early diagnosis of HCC in post-chronic hepatitis C (CHC) cirrhotic patients. Patients and Methods: A comparative study included 60 patients, 40 patients with HCC (HCC group) and 20 patients of CHC without HCC (control group). Diagnosis of HCC was based on abdominal ultrasound and triphasic CT, while biopsy was performed in debating cases. Serum samples for measurement of GPC3 and AFP levels were obtained from all participants. Results: The median levels of both AFP and GPC3 were significantly higher among HCC cases compared to controls. Analysis of the ROC curve showed that both AFP and GPC3 could be used to differentiate HCC cases from controls. AUROCs of GPC3 and AFP were 0.928 and 0.727 respectively, and both were statistically significant with p-values Conclusion: Serum GLP-3 is highly sensitive and specific for detecting HCC, more than AFP for the early detection of HCC, and the combination of both yielded improved sensitivity.
