摘要 目的探讨血清高尔基体蛋白73(GP73)及甲胎蛋白(AFP)异质体3百分含量(AFP-L3(%)检测在AFP低浓度(1.0~108.0μg/L)肝癌中的诊断价值。方法选择临床诊断符合AFP低浓度肝癌患者(80例)、肝硬化患者(55例)及健康体检者(80人),测定3组人的血清GP73、总AFP及AFP-L3含量,并计算AFP-L3(%)。结果GP73和AFP-L3(%)在AFP低浓度肝癌组的检测值及阳性率,均高于肝硬化组和健康对照组;ROC曲线分析结果,GP73单项诊断AFP低浓度肝癌的曲线下面积0.887、敏感性37.5%、特异性97.8%、准确度75.3%;AFP-L3(%)单项诊断的曲线下面积0.933、敏感性10.0%、特异性99.3%、准确度66.0%;两者联合应用对AFP低浓度肝癌诊断的敏感性45.0%、特异性97.0%、准确度77.7%。结论血清GP73及AFP-L3(%)测定有助于检出AFP低浓度肝癌患者,两者联合可提高检测的敏感性与准确度,实现对肝癌的早期预警。
