摘要 目的检测非小细胞肺癌COX-2基因mRNA的表达水平并探讨其临床意义。方法运用两步法RT-PCR技术检测83例非小细胞肺癌组织和24例支良性非癌肺组织中COX-2基因mRNA的表达水平。结果 83例肺癌组织中检测出44例(53.01%)阳性,24例非癌肺组织中检测出2例(8.33%)阳性,其中在腺癌表达率67.31%显著高于鳞癌表达率35.48%,差异有统计学意义(P=0.005),淋巴结转移组中表达率(65.85%)显著高于无淋巴结转移组(42.86%)(P=0.036)。低分化组中表达率(85.00%)显著高于高、中分化组表达率(55.56%)(P=0.018)。结论 COX-2基因在肺癌组织与非癌肺组织中mRNA表达差异有统计学意义(P=0.000),COX-2表达与肺癌病理类型密切相关,揭示了COX-2可以作为判断病情和预后评价的指标。
