摘要 目的:探讨胃癌组织中Survivin、Cox-2与HIF-1α蛋白的表达及其临床意义。方法:采用免疫组织化学染色法检测Survivin、Cox-2及HIF-1α在65例胃癌组织、18例癌旁组织及20例正常胃黏膜的表达水平,并分析其与胃癌生物学行为的关系。结果:Survivin、Cox-2与HIF-1α在正常胃黏膜、癌旁组织、癌组织中的表达呈升高趋势,其差异均有统计学意义(P<0.05)。Survivin阳性表达在TNM分期、组织学分化程度、胃癌浸润深度、淋巴结转移及远隔转移方面差异显著(P<0.05);Cox-2阳性表达在TNM分期、组织学分化程度和淋巴结转移方面差异显著(P<0.05);HIF-1α阳性表达在TNM分期、组织学分化程度、胃癌浸润深度和淋巴结转移方面差异显著(P<0.05)。相关分析显示,65例胃癌组织中,Survivin、Cox-2与HIF-1α表达均呈正相关(r=0.285,0.405,0.546,P<0.05)。结论:Survivin、Cox-2与HIF-1α的过表达在胃癌的发生、发展、浸润和转移过程中发挥协同作用,可成为胃癌基因诊断和治疗的新靶点。
