2、在大肠癌组织中的表达及其与肝转移的关系。方法:采用免疫组化法分别检测伴肝转移大肠癌的原发灶与肝转移灶、无肝转移大肠癌组织以及正常肠管黏膜组织中CEA的表达,比较CEA在上述4种组织中阳性表达率与表达强度的差异。结果:伴肝转移大肠癌的原发灶、肝转移灶、无肝转移大肠癌组织中CEA的阳性表达率分别为97.22%、100%、91.67%,均高于正常肠管黏膜组织(19.44%)(均P伴肝转移大肠癌原发灶>无肝转移大肠癌组织>正常肠管黏膜(均P3、EA的高表达可能预示大肠癌的肝转移风险增高。【中国普通外科杂志,2014,23(1):69—73】关键词肝肿瘤/继发性;结直肠肿瘤;癌胚抗原中图分类号:R735.7RelationshipofCEAexpressionincolorectalcancertissueandlivermetastasisXUYuanbing。一,LINYuan‘,JtNQinwen。,LIUYi‘,CHENJiansi‘,HUChaohuarI.DepartmentofGeneralSurgeryfJJ,XiaoganCentralHospital,Xiaogan,Hubei4334、200,China;2.DepartmentofGastrointestinalSurgery,AffiliatedCancerHospital,GuangxiMedicalUniversity,Nanning53002I,China)Correspondingauthor:LINYuan,Email:gxlinyuan789@126.comABSTRACTObjective:Toinvestigatethecarcino—embryonicantigen(CEA)expressionincolorectalcancertissueanditsrelations5、hipwithlivermetastasis.Methods:TheCEAexpressionsinthetissuesthatincludedtheprimarylesionandlivermetastasesoflivermetastaticcolorectalcancer,andcolorectalcancerwithoutlivermetastasisaswellasnormalcolorectalmucosaweredetectedbyimmunohistochemicalstaining.TheCEApositiveexpressionratesan6、dexpressionintensitiesamongtheabove4typesoftissueswerecompared.Results:TheCEApositiveexpressionrateintheprimarylesionandlivermetastasesoflivermetastaticcolorectalcancer,colorectalcancertissuewithoutlivermetastasisandnormalcolorectaltissuewas97.22%,100%,91.67%and19.44%respective1)5whi7、chwereallsignificantlyhigherthanthatinthenormalcolorectalmucosa(19.4%)(al1P<0.0s).TheCEAexpressionintensityinasignificantlyincreasedtodecreasedorderwas:livermetastases,收稿日期:2013—11-20;修订日期:2013—12—27。作者简介:徐元兵,湖北省孝感市中心医院住院医师,主要从事肝胆、胃肠、乳腺肿瘤方面的研究。通信作者:林源,Emaihlinyuan789@126.com@皈权l扭串国普通8、外科杂志所有http:/
