摘要
目的初步探讨咽喉反流与喉癌的相关性。方法选取2011年1月2013年12月期间的喉鳞状细胞癌患者的肿瘤组织标本32例作为喉癌组,2011年1月2013年12月期间的喉鳞状细胞癌患者的肿瘤组织标本32例作为喉癌组,2011年1月2014年3月间行尸检的喉部正常者声带组织标本19例作为正常组,采用免疫组化方法检测2组标本胃蛋白酶表达水平,比较两组其表达强度。结果喉癌组肿瘤组织中胃蛋白酶表达量强阳性4例(12.5%,4/32),阳性10例(31.25%,10/32),弱阳性14例(43.75%,14/32),阴性4例(12.5%,4/32);正常组声带组织中胃蛋白酶表达弱阳性4例(21.05%,4/19),阴性15例(78.95%,15/19),无强阳性及阳性表达,喉癌组胃蛋白酶表达的阳性率显著高于正常组(P<0.001)。结论喉癌组织中胃蛋白酶阳性表达率明显高于正常声带组织,提示咽喉反流可能与喉癌存在相关性,可能是喉癌发生的危险因素之一。
