摘要 目的探讨上皮性钙粘蛋白(E-cadherin)及神经性钙粘蛋白(N-cadherin)在乳腺癌中表达的相关性及临床意义。方法选取2014年1月-2017年6月期间该院诊治的乳腺癌患者128例为研究对象,统计128例乳腺癌组织、128例乳腺癌癌旁组织、128例腋窝转移淋巴组织中E-cadherin及N-cadherin的表达阳性率,就3组临床病理资料进行统计学分析。结果(1)E-cadherin在癌旁组织、肿瘤组织、腋窝转移淋巴组织中表达的阳性率分别是92. 97%、53. 13%、35. 16%,两两比较差异有统计学意义(P<0. 05); N-cadherin在癌旁组织、肿瘤组织、腋窝转移淋巴组织中表达的阳性率分别是6. 25%、43. 75%、57. 81%,两两比较差异有统计学意义(P<0. 05);(2) E-cadherin在乳腺癌组织中的阳性表达率是53. 13%(68/128),N-cadherin在乳腺癌组织中的阳性表达率是43. 75%(56/128),均与其淋巴结转移、病理分级、c-er B-2阳性存在相关性(P<0. 05);(3)E-cadherin表达阳性组中N-cadherin的阳性表达率是11. 76%(8/68),E-cadherin表达阴性组中的N-cadherin的阴性表达率是80. 00%(48/60),两者差异有统计学意义(P<0. 05),且E-cadherin、N-cadherin之间在乳腺癌表达中呈现负相关(P<0. 05)。结论 E-cadherin蛋白表达降低、N-cadherin蛋白异常表达同乳腺癌发生、浸润转移均存在密切相关性,且E-cadherin转化为N-cadherin机制在乳腺癌进展中可能发挥重大作用。
