1、山西医科大学硕士学位论文胃癌组织中PTEN和VEGF、PCNA、bcl-2表达的相关性研究姓名:郭建红申请学位级别:硕士专业:病理学指导教师:李士瑛2003.6.9生兰苎!!圭兰翌型!塑、_胃癌组织中PTEN幂口VEGF、PCNA、bcI一2表达的相关性研究研究生郭建红导师李士瑛教授摘要目的:通过对PTEN和血管内皮生长因子(vascularendothelialgro州hfactor,vEGF)、增殖细胞核抗原(Proliferatingcellnuclearantigen,PCNA)、bcl.2在胃癌中表达的研究,结合临床病理特征,探讨PTEN和VEGF、PcNA、bc
2、l.2的相关性.方法:应用免疫组织化学s.P法检测68例胃癌组织及20例正常胃粘膜中PTEN、VEGF、PcNA和bcl一2的表达。结果:胃癌组织中PTEN蛋白表达率为47.1%(33/68),显著低于正常胃粘膜的表达100%(20/20)(P<0.01),与组织分化程度呈正相关(P3、。PcNA在胃癌小的表达率为73.5%(50/68),显著高于JJ三常胃粘膜的表达20.0%(4/20),与癌组织浸润深度呈正相关fP4、联合检测PTEN、vEGF和PcNA,有助=丁二提高胃癌侵袭转移能力的评估,对胃癌的预后判断具有重要的临床意义。关键词:胃癌PTENvEGFPcNAbcl一2免疫组织化学CorrelationbetweenProteinExpressionofPTENandVEGl●PCNA,bcl.2inHumanGastricCarciIlomaAbstractobjectiVe:ThisstudywasdesignedtoinvestigatetheexpressionofPTENandVascularendothelialgmwthfactor(VEGF),Proliferatin5、gcellnuclearantigen(PCNA),bcl一2in.3-山曲医科大学硕士学位论文gastriccarcinonlaandnonnalgastr.cmucosa,andtherelationshipbetweentheirexpressionandclinicalpathologicalfactors.Methods:TheexpressionofPTENandVEGF、PCNA、bcI一2in68casesofgastriccarcinomaand20casesofnonllalgastricmucosawasdetectedusillgImnlunohis6、to—chelnicalS—Pmethod.ResuIts:33casesweredefectedpositivestainingofPTEN(47.1%)i1168cases譬astriccarcinoma,whileall20casesnonllallnucosashowedpositivestainingofPTEN.TheexpressionlevelofPTENinhighdif五。J.entiatedadenocarcinomawashigherthanthatinlowdifferentiatedadenocarcinoma.Also.thelossordec7、reasedexpressionofPTENwassignificantlycorreIatedwithJymphnodemetastasisandin丘Itrativedeepness.In68casesgastriccarcinoma,51cases(75.0%)and50cases(73.5%)weredetectedposj“veslainjngofVEGFandPCNA,respectively.whilein20casesnormalgastricmucosa,only2casesand4casessh
