Abstract： 目的:探讨食管鳞癌中是否存在TGF-β1引发的EMT,及其与食管鳞癌的浸润转移的关系.方法:选用郑州大学第一附属医院2000-01/2004-12食管鳞癌手术切除标本100例,每例标本均选用癌组织中心及其远端正常黏膜对照.采用免疫组织化学技术检测100例食管鳞癌手术切除标本中的TGF-β1、E-cadherin和Vimentin蛋白的表达.结果:TGF-β1蛋白在食管鳞癌组织中的表达明显高于正常黏膜(85% VS 27%,P<0.01),其在深层浸润组中的表达高于浅层浸润组(91%VS 75%,P<0.05);E-cadherin蛋白在食管鳞癌组织中的表达明显低于正常黏膜(43% VS 85%.P<0.01);Vimentin蛋白在食管鳞癌组织中的表达高于正常黏膜(23% VS 0%,P<0.05);食管鳞癌组织中,TGF-β1与E-cadherin表达呈负相关(Tb=-0.257,P=0.013),而与Xrtmentin表达呈正相关(Tb=0.163,P=0.030),E-cadherin与Vimentin表达呈负相关(Th=-0.379,P=0.000).结论:食管鳞癌中可能存在TGF-β1引发的EMT,且可能与食管鳞癌的浸润转移有关.
