1、检验医学与临床2014年2月第11卷第3期LabMedClin,February2014,Vo1.11,No.3·307··论著·微量离心柱法检测肝癌患者血清甲胎蛋白异质体临床意义分析黄海深,周永均,何兰香。,李宇呜,唐光定,陈国强(1.清远市阳山县人民医院检验科,广东清远513100;2.清远市阳山县疾控中心,广东清远513100)【摘要】目的探讨微量离心柱法检测血清甲胎蛋白(AFP)异质体(AFP—L3)在肝癌诊断及良、恶性肝病鉴别诊断中的临床应用价值。方法选择2O11年6月至2O12年1O
2、月于阳山县人民医院就诊的原发性肝癌(PIc)患者8O例(PLC组)、肝硬化患者66例(肝硬化组)和慢性肝炎患者54例(慢性肝炎组)作为研究对象,应用国产微量离心柱法试剂分离纯化血清AFP-L3,采用化学发光法检测血清AFP和AFP—L3水平,并计算AFP—I3在总AFP中所占比例(AFP—L3)。结果PLC组患者血清AFP、AFP—L3水平均高于肝硬化组和慢性肝炎组(P<0.05)。以AFP>25ng/mL,AFP-L3≥10作为阳性判断标准,PLC组患者血清AFP阳性率高于肝硬化组和慢性肝炎组
3、,且PLC组患者血清AFP-L3阳性率亦明显高于肝硬化组和慢性肝炎组(P<0.05),但具有不同血清AFP水平的PLC患者之间,血清AFP—L3水平和阳性率比较差异均无统计学意义(P>0.05)。结论微量离心柱法检测血清AFP.L3在肝癌的早期诊断和良、恶性肝病的鉴别诊断中具有重要价值。【关键词】微量离心枉法;甲胎蛋白异质体;原发性肝癌DoI:10.3969/j.issn.1672-9455.2014.03.008文献标志码:A文章编号:1672—9455(2O14)03—0307—03Appl
