摘要 目的:探讨雌激素受体(ER)及孕激素受体(PR)在不同程度宫颈上皮内瘤病变(CIN)组织中的表达及与人乳头瘤病毒(HPV)的关系。方法:采用免疫组化SP法染色观察ER及PR在160例CIN及正常宫颈组织的表达情况,同时采用PCR方法检测高危型HPV感染。结果:ER在慢性宫颈炎、CINⅠ组、CINⅡ组、CINⅢ组的阳性表达率分别是100.0%、67.9%、40.6%、12.0%;PR在以上各组的阳性表达率分别为29.4%、28.6%、18.8%、1.0%。从慢性宫颈炎到CINⅢ组,ER、PR阳性表达率逐渐降低,ER的表达在各组之间有显著性差异,而PR的表达在各组之间无显著性差异。CIN合并高危型HPV感染的患者行宫颈锥切术后,ER在HPV(+)组阳性表达率为92.9%,在HPV(-)组的表达率为56.7%,两组比较差异有统计学意义。结论:对CIN病变宫颈组织进行ER测定,有助于判断病变的程度,指导治疗。宫颈锥切术后局部ER表达增高,可能促进HPV的增殖,是导致HPV持续感染的重要原因之一。
