摘要
目的探讨乳腺浸润性导管癌组织中上皮间质转化(EMT)分子标记物E-钙黏蛋白、N-钙黏蛋白、基质金属蛋白酶9(MMP-9)和MDM2蛋白的表达及其与临床病理特征和预后的关系。方法应用免疫组织化学法检测242例乳腺浸润性导管癌患者手术标本中E-钙黏蛋白、N-钙黏蛋白、MMP-9和MDM2蛋白的表达水平,并进行统计分析。结果在乳腺浸润性导管癌组织中,E-钙黏蛋白、N-钙黏蛋白、MMP-9和MDM2的阳性表达率分别为70.7%、2.9%、54.9%和49.6%,其中,E-钙黏蛋白与MMP-9的表达呈正相关(r=0.238,P=0.000),MDM2与MMP-9的表达也呈正相关(r=0.171,P=0.012)。E-钙黏蛋白的表达与肿瘤大小及雌激素受体(ER)状态有关,肿瘤较小及ER阳性者的E-钙黏蛋白阳性表达率高;MDM2的表达与肿瘤大小也存在显著相关性(P=0.028),肿瘤较小者的MDM2阳性表达率高。生存分析显示,肿瘤较大、淋巴结转移及MDM2表达阳性者的术后无病生存期较短,其中淋巴结转移(HR=11.33,95%CI:3.46~37.13,P<0.001)和MDM2表达阳性(HR=5.17,95%CI:1.66~16.10,P=0.005)是乳腺浸润性导管癌患者的独立不良预后因素。结论 MDM2是乳腺浸润性导管癌的不良预后因子之一,MDM2可能通过上调MMP-9的表达,介导EMT发生,导致肿瘤浸润转移影响预后。
