BACKGROUND: Alpha-fetoprotein (AFP) levels are routinely used for diagnosis and monitoring of hepatic diseases, but it has a limited value. Golgi protein 73 (GP73) has been suggested as a new marker for hepatic diseases. OBJECTIVE: To explore the clinical value of serum GP73 in different diseases associated with hepatitis B virus (HBV) infection. METHOD: Between January 2010 and August 2014, serum samples from 88 patients with chronic hepatitis B (CHB), 78 patients with HBV-related liver cirrhosis (LC), and 194 patients with HBV-related primary hepatic cancer (PHC) were collected. Serum samples from 30 healthy volunteers were used as controls. ELISA and microparticle enzyme immunoassay were used to measure serum GP73 and AFP levels. Receiver operating characteristic (ROC) curves were used to analyze the diagnostic value of serum GP73 and AFP for PHC. RESULTS: For the diagnosis of PHC, GP73 showed a sensitivity of 65.5% and specificity of 66.3%, while AFP levels showed sensitivity of 64.4% and specificity of 76.5%. Serial testing (both tests are positive) could increase the specificity (sensitivity of 45.9% and specificity of 85.5%) while parallel testing (any single positive test result) could increase the sensitivity (sensitivity of 84.0% and specificity of 57.2%). Serum GP73 and AFP levels were significantly different between Child-Pugh grades (P<0.001 for GP73 and P=0.044 for AFP). Significant differences in serum GP73 and AFP were found between TNM stages (all P<0.001). CONCLUSION: Serum GP73 had limited diagnostic value for HBV-related PHC. The combined use of serum GP73 and AFP levels improved the diagnostic efficacy.
