MMP-9、EGFR和E-cadherin在非小细胞肺癌中的表达及意义

Expression and Significance of MMP-9、EGFR and E-cadherin in NSCLC

  • 摘要: 目的 探讨基质金属蛋白酶 9(MMP 9)、表皮生长因子受体 (EGFR)和上皮性钙黏附蛋白 (E cadherin, E cad)在非小细胞肺癌 (NSCLC)中的表达及临床意义。方法 采用免疫组织化学 (SP)法检测MMP 9、EGFR和E cad在 6 2例NSCLC组织和 18例正常肺组织中的表达。结果  (1) 6 2例NSCLC中MMP 9和EGFR阳性表达率分别为 6 7.7%和 5 8.1%, E cad的异常表达率为 5 1.6 %, 显著高于癌旁正常肺组织 (P <0 .0 0 5 ) ;(2 )MMP 9、EGFR和E cad的表达水平在NSCLC不同病理分级、不同临床TNM分期以及有无淋巴结转移间比较均有显著差异 (P均 <0 .0 5 )。 (3)MMP 9、EGFR、E cad的表达水平在NSCLC不同病理类型间比较无明显差异 (P均 >0 .0 5 )。结论 检测MMP 9、EGFR、E cad的表达水平, 对判断NSCLC恶性程度有重要意义。

     

    Abstract: Objective To study the clinical significance of the expression of matrix metalloproteinase-9(MMP-9)、epidermal growth factor receptor (EGFR)、E-cadherin(E-cad) in patients with non-small cell lung cancer(NSCLC). Methods Immunohistochemical method (SP) was used to detect the expression of the MMP-9、EGFR、E-cad in 62 NSCLC tissues and 18 normal lung tissues. Results (1) The positive expression rates of MMP-9 and EGFR were 67.7%、 58.1% respectively in the 62 NSCLC. The abnormal expression rate of E-cad w...
