喉癌组织ICE基因蛋白表达与喉癌临床的相关性研究

目的 :探讨喉癌组织白细胞介素 1β转换酶 (ICE)基因蛋白表达与喉癌发生、发展的关系。 方法 :采用免疫组化SP法测定 5例正常人声带组织、30例癌旁鳞状上皮不典型增生组织和 73例喉癌组织标本中ICE基因蛋白表达。结果 :ICE主要表达于正常人喉上皮棘层及角化层细胞胞膜 ,基底层细胞呈阴性或弱阳性表达 ,随着正常喉上皮向不典型增生转变 ,其ICE蛋白表达明显减少。喉癌组织中ICE基因蛋白表达与癌细胞分化程度有关 ,细胞分化程度越好ICE表达越强 (P <0 .0 5 )。结论 :ICE蛋白分布形式和数量变化与喉不典型增生有关 ,ICE的表达与喉癌的预后有一定的关系 ,可作为喉癌预后的一个监测指标

ICE expression in laryngeal carcinoma and it''''s clinical relationship

OBJECTIVE: To study the role of ICE in Laryngeal Carcinoma. METHOD: Using polyclonal antibody for ICE gene protein, 73 cases of laryngeal carcinoma, 30 cases dysplasia and 5 cases normal were stained by SP immunohistochemistry. RESULT: ICE protein is situated mainly in the upper of epithelium and a little in the basal layer. Compared with the normal epithelium, the expression of ICE in the dysplasia is decreased significantly (P < 0.01). There is a relationship between expression of ICE in laryngeal carcinoma and the degree of differentiation. The better differentiation, the much expression of ICE (P < 0.05). CONCLUSION: There is an intimate relationship between innormal expression protein of ICE and dysplasia, and that of between laryngeal carcinoma and prognosis. The expression of ICE may be a monitoring marker for prognosis of laryngeal carcinoma.
