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~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。Objective To study the correlation of laryngopharyngeal reflux and laryngeal carcinoma, tvtettx:Methods The laryngeal carcinoma specimens of 32 patients with laryngeal carcinoma confirmed pathologically from January, 2011 to De- cember, 2013 and 19 autopsy tissues of non-- laryngocarcinoma from January, 2011 to March, 2014, were collected. The im- munohistochemical staining was used to detect pepsin. The result of these two groups were statistically analyzed. Results In 4(12.5%) of 32 laryngeal carcinoma specimens expression of pepsin showed strong positive, 10(31.25%) of which showed positive,14(43.75%) of which showed weak positive,4(12.5%) of which showed negative. In 4 of 19(21.05%) autopsy specimens expression of pepsin showed weak positive, 15(78.95%) of which showed negative, none of which showed strong positive or positive. There were statistical differece between these two groups(P〈 0. 001). Gonclusion Pepsin in the laryngopharyngeal reflux has correlation to laryngeal carcinoma ,which may be a risk factor in the development of the laryngeal carcinoma.
