摘要 目的探讨年轻女性宫颈上皮内瘤变(CIN)2级组织p16INK4a的表达与病变级别及转归的相关性。方法选取2010年1-12月在北京大学第一医院妇产科门诊就诊的年龄≤35岁、经病理诊断的CIN2患者36例,按照年龄将其分为<30岁组(12例)和30~35岁组(24例),采用免疫组化法对其宫颈活检组织进行p16INK4a检测,并采用两个结果判断标准对患者的转归进行随访。结果 CIN2组织中p16INK4a阴性、弱阳性和阳性(>50%)的表达率分别为11.1%(4/36)、8.3%(3/36)和80.6%(29/36);美国下生殖道鳞状上皮病变项目(LAST projet)分流标准p16INK4a连续弥漫全层阳性的表达率为63.9%(23/36)。其中年龄<30岁组p16INK4a>50%阳性和弥漫全层阳性患者中,宫颈环状电切术(LEEP)后诊断为CIN3的比例分别为1/9和1/7;而30~35岁组两者的比例分别为4/18和3/15,两者比较,差异均无统计学意义(P>0.05)。36例患者平均随访(13.4±3.9)个月,未发现病变进展。结论对CIN2组织中p16INK4a阳性患者进一步行LEEP或锥切是必要的;p16INK4a对预测CIN转归的意义仍需进一步研究。
