Clinical value of serum GP73 detection in patients with hepatocellular carcinoma

Objective To explore the clinical application value of the serum GP73 detection in the diagnosis of hepatocellular car-cinoma(HCC).Methods The expression level of serum GP73 protein was quantitatively detected by ELISA,including 52 cases of healthy individuals,45 cases of non-hepatic disease,43 cases of viral hepatitis B,20 cases of liver cirrhosis and 30 cases of HCC;The levels of GP73 were compared among the 5 groups.Serum a-fetoprotein(AFP)level in the HCC patients was detected by electro-chemilumnescence(ECL)method.The area of receiver operating curve(ROC),sensitivity and specificity of GP73 and AFP for diag-nosing HCC were calculated.Results The serum level of GP73 was (58.57 ± 35.64)ng/mL in the non-hepatic disease group, (70.36±49.88)ng/mL in the viral hepatitis B group,(114.47±51.27)ng/mL in the liver cirrhosis group and (251.37±95.6)ng/mL in the HCC group,which in the patients was significantly higher than(34.03±15.20)ng/mL in the healthy control group,the differences had statistical significance(P <0.05);The serum GP73 level in the HCC group was significantly higher than that in the other groups with statistical difference(P <0.01);The positive detection rate of serum GP73 in the HCC group was 76.7%,which was significantly higher than 3.12% in the non-HCC group,the difference had statistical significance(χ2 =108,P <0.05);The sen-sitivity and specificity of GP73 for diagnosing HCC were 75.1% and 94.9% respectively,which were significantly higher than those of the AFP(52.3% and 86.6%).Conclusion GP73 could be to become a better serum marker for diagnosing HCC.
