摘要
目的研究肿瘤干细胞标志物CD133和内皮素转化酶(ECE)在非小细胞肺癌(NSCLC)组织中表达的临床意义。方法用免疫组织化学方法检测77例NSCLC组织中CD133和ECE的表达,分析其与肿瘤大小、组织学类型、组织分化程度、淋巴结转移和预后的关系。结果77例NSCLC组织中CD133与ECE的阳性表达率分别为51.9%(40/77)和45.5%(35/77)。CD133和ECE的表达与淋巴结转移呈正相关(r=0.246,P<0.05;r=0.339,P<0.05);CD133和ECE的表达均与患者术后生存时间呈负相关(P<0.05)。CD133和ECE的表达与肿瘤大小、组织学类型和组织分化程度均无关(P>0.05)。CD133与ECE的表达之间呈正相关(r=0.249,P<0.05)。结论肿瘤干细胞标志物CD133和ECE的表达与NSCLC的淋巴转移和预后密切相关,它们的高表达提示患者预后不良。
