Pilot study evaluates glypican-3 levels in HCC patients, suggesting potential improvements in diagnostic accuracy.
Background: Early diagnosis of hepatocellular carcinoma (HCC) and monitoring of therapeutic results remain clinical challenges. Methods: In a prospective study, we evaluated the diagnostic capabilities of the serum level of glypican-3 in 70 patients with chronic advanced compensated liver disease: 40 cases with confirmed HCC and 30 cases with chronic viral hepatitis with bridging fibrosis or cirrhosis as a control group. The glypican-3 concentration was analyzed in the context of the disease characteristics. Results: The mean level of glypican-3 in HCC patients was 50.84 ± 75.98 ng/mL, significantly higher compared to the control group of 5.69 ± 10.43 ng/mL. A progressive increase in alpha-fetoprotein in accordance with the stage of neoplastic disease was observed, but this tendency was not assessed for glypican-3. Two cut-off levels can be suggested for glypican-3: 2.5 ng/mL to exclude HCC with an optimal sensitivity of 85%, and 33.7 ng/mL for confirmation of HCC, with a specificity of 96.7%. The diagnostic accuracy of serum glypican-3 was 80.0% for HCC, 82.1% for alpha-fetoprotein, and 87.4% for both tumor markers. Conclusions: This pilot study suggests a complementary role of glypican-3 with alpha-fetoprotein and better diagnostic performance when combining tumor biomarkers.
