摘要 目的:研究环氧合酶-2(COX-2)、p53基因在食管鳞癌组织中的表达及其临床意义。方法:采用免疫组化染色S-P法检测COX-2、p53蛋白在67例食管鳞癌组织及15例癌旁组织中的表达。结果:COX-2和p53在食管癌组织中的阳性表达率分别为73.5%(49/67)和64.2%(43/67),均高于癌旁组织(P<0.05)。COX-2在高、中、低分化食管癌中的表达率逐渐降低(P<0.05);有嗜酒史者阳性表达率明显高于无嗜酒史者(P<0.05)。p53高表达与食管癌淋巴结转移及嗜酒史有关(P<0.05)。COX-2与p53表达具有相关性(r=0.249,P<0.05)。结论:COX-2和p53均可能参与了食管癌的发生过程。不同分化食管鳞癌的COX-2表达率有差异,COX-2表达率与嗜酒可能相关。p53高表达与食管癌淋巴结转移及嗜酒史可能相关。
