摘要 目的 检验p16、p27蛋白在宫颈癌中的表达,探讨它们在宫颈癌发生发展中的作用及其与宫颈癌的临床病理特征关系。方法 收集56例手术切除宫颈癌标本,同时取20例正常宫颈组织,应用免疫组化EnVision二步法,检测宫颈癌组织及正常组织中的p16、p27蛋白表达。结果 p16和p27蛋白在正常宫颈组织的表达率为100%(20/20)、95%(19/20),而在宫颈癌的表达则分别为53.6%(30/56)、35.7%(20,56),(P<0.05),在FIGO分期早期的宫颈癌阳性表达率高,与宫颈癌分化程度呈正相关(P<0.05)。结论 p16、p127蛋白失活可加速细胞周期转化,促进宫颈癌的发生发展。p16和p27蛋白的检测可作为评价宫颈癌恶性程度和判断预后的重要指标。
