摘要 目的探讨COX-2基因在大肠癌中表达的意义。方法收集手术切除的大肠癌标本58例,同时选取大肠癌远端正常黏膜组织10例,应用流式细胞术(FCM)检测大肠癌及正常黏膜中COX-2表达情况,根据平均荧光强度计算荧光指数(FI)。结果 COX-2表达平均FI值正常黏膜组为1.00±0.28,高、中、低分化及黏液癌组分别为2.47±1.41、2.70±1.08、3.16±1.34和2.01±1.43,高、中、低分化及黏液癌组COX-2表达均明显高于正常黏膜组(P<0.01);大肠癌淋巴结转移组平均FI值(2.45±1.41)显著高于无淋巴结转移组(1.61±1.27)(P<0.05)。COX-2的表达与患者的年龄、性别、肿瘤的发生部位等无关。结论 COX-2在大肠癌中表达异常增高,并与淋巴结转移密切相关。
