AFP与CA199、CA125联合检测在诊治原发性肝癌中的意义易春生黄泽亮周波廖东承余鹏飞(湖南省怀化市第二人民医院418000)【摘要】目的分析比较原发性肝细胞摘(hepatocellularcarcinoma,HCC)患者血清AFP、CA199、CA125水平,找出它们之间的相关性。方法选择2007年3月〜2013年10月在我院肝胆外科、肿瘤科治疗的138例HCC患者,及同院内科、传染科治疗的50例肝硬化、乙型肝炎患者和100名健康体检者,用化学发光法对血清AFP、CA199、CA125进行检测和比较分析。结果138例HCC患者AFP阳性率73.9%、CA199阳性率69.6%、CA125阳性率65.2%;AFP阴性的HCC患者中,CA199和CA125有较高的阳性率,经手术治疗后,均明显降低,经放化疗,有些升高,有些降低。结论AFP与CA199、CA125联合检测,可明显提高HCC阳性诊断率,特别对AFP阴性的HCC患者,检测CA199、CA125不仅可作为诊断的参考指标,而且可作为疗效观察,预后评估和复发监测的重要指标。【关键词】HCCCA199CA125AFP【中图分类号】R735.7【文献标识码】A【文章编号】1672-5085(2013)49-0021-02SignificancesofCombineddetectionofAFP,CA199andCA125inprimaryhepatomadiagnosis丫IChunsheng,HUANGZeliang,ZHOUBo,SUNWeihua,LIAODongcheng,YUPengfei(SecondPeople’sHospitalofHuaihua,Hunan418000,China)【Abstract】ObjectiveThroughanalysisandcomparisonofAFP,CA199,CA125levelinserumofprimaryhepatocellularcarcinoma(HCC)patients,toidentifythecorrelationbetweenthem.MethodsAtotalof138serumsamplesfromHCCpatientsofHepatobiliaryandOncology,50serumsamplesfrompatientswithCirrhosisandHepatitisBfromMedicinedepartmentandinfectiousdepartmentand100serumsamplesofhealthypeoplewereobtainedfromMarch2007toOctober2007.Allsamplesweredetectedandcomparedbyusingchemiluminescence.ResultsIn138serumsamplesfromHCCpatients,AFPshowed73.9%ofpositiverate,CA199showed69.9%ofpositiverate,CA125showed65.2%ofpositiverate.InserumsamplesofAFP-negativeHCCpatients,CA199andCA125hadahigherpositiverate.Aftersurgery,theyweresignificantlyreduced.Afterchemotherapy,somewereelevatedandsomewerereduced.ConclusionCombineddetectionofAFP,CA199andCA125cansignificantlyimprovethediagnosticyieldofpositiveHCC.EspeciallyforAFP-negativeHCCpatients,detectionofCA199andCA125cannotonlybeusedasareferenceforthediagnosis,butalsoasanimportantindicatorofefficacy,prognosisandrecurrencemonitoring.【Keywords】HCCCA199CA125AFP原发性肝细胞癌是常见恶心肿瘤之一,以亚非地区尤甚;在我国,肝癌0前为癌症第二杀手,在部分肝癌高发区己跃居第一位[1-2]。原发性肝癌,约80%的病人血清中AFP含量增高(>300ng/ml)oAFP是筛选和诊断无临床症状小肝癌的主要方法,其•含量显著升高,大于500ng/ml,持续4周,或大于200ng/ml,持续8周,或由低浓度逐渐升高不降,在排除妊娠和生殖胚胎瘤基础上,一般提示原发性肝细胞癌。AFP用于肝癌辅助诊断的报道较多,但是其诊断HCC的敏感度和特异度不高[3】。原发性肝癌,CA199与CA125可增高,其用于辅助诊断肝癌的敏感度和特异度的报道很少。将AFP与CA199、CA125联合检测,可明显提高HCC阳性诊断率。1资料与方法1.1一般资料(1)选择2007年3月〜2013年10月在我院肝胆外科、肿瘤科治疗的138例经我院病理确诊为原发性肝细胞癌患者,年龄38〜72岁,平均年龄56岁,男96例,女42例;同院内科、传染科治疗的肝硬化、乙肝患者50例,其中肝硬化28例,乙型肝炎22例,年龄26〜68岁,平均年龄52岁。以AFP>20ng/ml为阳性,CA199>37U/ml为阳性,CA125>35U/ml为阳性。(2)同院健康体检者100名,男58名,女42名,年龄23〜68岁,平均年龄42岁。1.2仪器与试剂AXSYM型化学发光分析仪,原装进口配套试剂,由美国雅培公司提供。1.3方法抽取待检者清晨空腹静脉血4ml,室温放置1小时,然后300*g分离血清。采用微粒子酶联免疫(MEIA)检测法测AFP、CA199和CA125,测试均严格按试剂说明书操作。微粒子酶联免疫分析法是雅培公...
