高尔基体糖蛋白73、磷脂酰肌醇蛋白聚糖3、甲胎蛋白异质体百分比联合检测在原发性肝癌诊断中的应用

Application of combined detection of Golgi glycoprotein 73,phosphatidylinositol proteoglycan 3 and percentage of AFP heteroplasmon in diagnosis of primary hepatocellular carcinoma

目的探讨高尔基体糖蛋白73(GP-73)、磷脂酰肌醇蛋白聚糖3(GPC3)、甲胎蛋白异质体百分比(AFP-L3%)联合检测在原发性肝癌诊断中的应用。方法选择肝癌患者154例(肝癌组),肝硬化患者78例(肝硬化组),健康对照者56例(对照组),用酶联免疫法分别测出GP-73、GPC3、AFP-L3的浓度。然后分别按照检测项目统计分析。结果肝癌组中GP-73、GPC3、AFP-L3%的水平明显高于肝硬化组和对照组(P<0.05);肝癌组中GP-73、GPC3、AFP-L3%的阳性率分别为66.2%、72.1%、53.2%。三项联合检测的阳性率可达到97.9%。高于任何单项和联合检测的敏感度和准确度。肝癌组中GP-73、AFP-L3%在AFP不同水平内比较,差异有统计学意义(P<0.05)。结论 GP-73、GPC3、AFP-L3%三者联合检测提高原发性肝癌诊断的敏感度和准确度,对鉴别诊断早期肝癌有参考意义。

Objective To study the application of the combined detection of Golgi glycoprotein 73（GP-73）,phosphatidylinositol proteoglycan 3（GPC3 ）and percentage of AFP heteroplasmon（AFP-L3%）in the diagnosis of primary hepatocellular carcinoma （PHC）.Methods The concentrations of GP-73,GPC3 and AFP-L3 were detected by enzyme-linked immunosorbent assay（ELISA） in 154 patients with PHC（PHC group）,78 patients with cirrhosis（cirrhosis group）and 56 healthy subjects（control group）.Then the detection results were statistically analyzed.Results The levels of GP-73,GPC3 and AFP-L3% in the PHC group were signifi-cantly higher than those in the liver cirrhosis group and the control group（P ＆lt;0.05）.The positive rates of GP-73,GPC3 and AFP-L3% in the PHC group were 66.2%,72.1% and 53.2% respectively.The positive rate in the combined detection of these three in-dices could reach 97.9%,which was higher than the sensitivity and accuracy in any single index detection and the combination de-tection.In the PHC group,the comparison between different levels of GP-73 and AFP-L3% with the AFP levels showed the statis-tically significant difference（P ＆lt;0.05 ）.Conclusion The combination detection of GP-73,GPC3 and AFP-L3% can improve the sensitivity and accuracy for diagnosing PHC and has reference significance in the differential diagnosis of early PHC.
