简介:目的:探讨AEG-1、P16、KI-67蛋白在宫颈癌前病变中的表达与临床意义。方法:2008年2月至2015年9月选择在我院诊治的宫颈癌前病变患者98例作为癌前病变组,同期选择宫颈癌患者98例作为宫颈癌组和98例健康体检人作为对照组,取三组的宫颈样本都进行AEG-1、P16、KI-67蛋白表达的免疫组化分析,并调查了临床资料进行相关性分析。结果:AEG-1、P16、KI-67蛋白在宫颈癌组的阳性表达率分别为80.0%、93.9%和92.9%,而癌前病变组为57.1%、50.0%和57.1%,在对照组为3.1%、2.0%和4.1%,三组间对比差异有统计学意义(P〈0.05)。AEG-1、P16、KI-67蛋白的阳性表达与宫颈癌前病变的年龄、疾病类型、HPV感染等病理参数对比差异有统计学意义(P〈0.05)。直线相关性显示AEG-1、P16、KI-67蛋白表达都呈现两两正向相关性(P〈0.05)。结论:AEG-1、P16、KI-67蛋白在宫颈癌前病变中都呈现高表达状况,且与临床病理特征存在相关性,三者可互相作用影响宫颈癌前病变的发展状况。
