摘要
目的探讨抑癌基因p16与喉癌的生物学行为的关系。方法采用免疫组织化学法检测39例喉癌中p16基因表达情况。结果喉癌组织p16阳性表达率为66.7%,p16蛋白阳性率在鳞癌Ⅰ、Ⅱ、Ⅲ级中分别为100%、64.7%。50%,显示p16蛋白表达阳性率随喉癌的病理分级的上升而降低,p16阳性与阴性组之间的1~5年的生存率则无明显差异。结论抑癌基因p16的表达与肿瘤的类型有关,而喉癌预后好于其它肿瘤可能与p16的失表达少有关。
Objective To approach the relationship between antioncogene p16 and the biologic behavior of laryngocarcinoma.Method Immunohistochemical staining was used to detect the expression of p16 gene in the specimens of 39 cases with laryngo-carcinoma.Results The positive rate of expression of p16 in the laryngocarcinoma was 66.7%. The positive rate of p16 ingrade and of squamous cell carcinoma was 100%, 64.7% and 50% respectively. It is suggested that the positive rate ofp16 decline with the grade elevation in pathology. There was no significant difference in 1 ~ 5 year survival rate between the pe tients with positive and negative p16. Conclusions The expression of P16 is related to the tumor type. The prognosis of laryn-gocarcinoma better than other tumors be correlated with the expression of antioncogene p16.
