Abstract： 目的研究环氧合酶-2(COX-2)在鼻咽癌中的表达及其对血管生成及预后的影响.方法选取临床资料完整并随访达5年以上的86例鼻咽癌患者,采用免疫组织化学技术检测活检标本中COX-2、血管内皮生长因子(VEGF)表达和微血管密度(MVD).结果 COX-2在鼻咽癌组织中阳性表达率为73.3%(63/86),与VEGF表达[69.8%(60/86)]呈显著正相关(rs=0.438,P<0.01),且与肿瘤分级、原发灶范围、颈淋巴结转移、远地转移及较短生存期亦具相关性.MVD平均数为32.3±12.8.结论 COX-2在鼻咽癌组织中高表达,与肿瘤血管生成密切相关,可作为预测鼻咽癌预后的一种有用指标.
