摘要 目的观察胃腺癌中基质金属蛋白酶(MMP)-19和上皮型黏附素(E-cadherin)的表达特征,分析其临床价值。方法 65例行胃腺癌手术后留取的标本作为研究组,收集距肿物边缘>3 cm的非肿瘤性胃黏膜组织20例作为对照组,应用免疫组化方法检测两组中MMP-19和E-cadherin的表达。结果研究组和对照组中MMP-19和E-cadherin表达的阳性率差异有统计学意义。研究组中MMP-19和E-cadherin表达的阳性率与肿瘤的脉管侵犯和转移密切相关,MMP-19表达的阳性率与肿瘤最大径密切相关,二者均与性别、年龄及浸润深度无明显相关性。线性相关分析显示研究组中MMP-19和E-cadherin的表达具有负相关性。结论胃腺癌中MMP-19高表达、E-cadherin低表达可以促进肿瘤的形成和进展。二者具有一定的协同作用,可能对肿瘤的转移有一定的调节作用。
