2、R+(En组且AR阳性)、En—AR一(En组且AR阴性)、Ep·AR+(Ep组且AR阳性)、Ep.AR。(Ep组且AR阴性),其中En.AR一又称为均阴性组,其他三组统称为部分或完全阳性组。不同分组方法比较与临床病理特征的关系。结果Ep组AR阳性率62.8%(54/86),En组AR阳性率37.9%(33/87),两组差异有显著性(P=O.001),AR阳性组体积小、核分裂少、组织学分级低(P3、组织学分级低(P<0.05),Ep组内AR阳性者临床分期高(P=0.000),En—AR+、Ep-AR+、Ep—AR一比较均无差异。结论AR在不同激素状态乳腺癌中表达的意义不同,ER、PR均阴性乳腺癌表达AR者预后较好,ER、PR阳性乳腺癌表达AR者临床分期高。在选择针对性药物时应考虑到不同激素受体状态的组合。关键词:乳腺肿瘤;受体,雄激素;受体,雌激素;PR;免疫组织化学中图分类号:R737.9;R347文献标识码:A文章编号:100l一7399(2010)01—0052一04Expression4、andsignificanceofandrogenreceptorinbreastcarcinoma、)I,itlldifferentERandPRstatusCHENJianl。ZHANGXu2。TIANRul,LIUYil,DONGHong.meil,GUORui.fen91,LIANGHua.yinl(’Depa疗memofPathology,No252HospitalofPIM,Baoding071000,China;2DepartmentofPediatrics,Bao击ngMaterna5、landChil-drenHealthHospital,Baoding071000,China)Abstract:PurposeToinvestigatetheexpressionandsignificanceofandrogenreceptor(AR)inbreastcarcinomawithdifferentERandPRsk帅s.MethodsImmunohistochemicalmethodWagusedtodetectAR.ERandPRexpressionin173casesofbrea6、stcal℃ino-眦,andalltheCagesweregroupedaccordingto:(1)ARstatus:AR—positivesubgroupandAR—negativesubgroup,(2)ERstatus:Ensubgroup(negativeforbethERandPR),Epsubgroup(positiveforERand/orPR),(3)AR,ERandPRstatus:En-AR+sub-group(AR—positivecasesofEnsubgroup),En7、·AR—subgroup(AR’negativeeasesofEnsubgroup),Ep—AR+subgroup(AR—posi-tirecasesofEpsubgroup),andEp—AR—subgroup(AR—negativeca8e8ofEpsubgroup).En—AR—subgroupalsoWagcallednegative-f撕一allsubgroup,andtherestthreesubgroupswerecalledpartly·or-completelypositivesu8、bgroup(positiveforatleastoneofthethreemarkers),andthen,thegroupswerecomparedwithclinicopathologicalfeatures.ResultsThepositiverateofARWag62.8%(54/86)inEpsubgroupand37.9%(33/87)inEnsubgroup,andtherewassignificantdifferencebetweenthem(P=0
