摘要 目的通过观察细胞核增殖抗原ki-67在子宫内膜异位症中的表达,探讨子宫内膜细胞增殖能力对子宫内膜异位症发病的影响。方法应用免疫组化SP法检测58例子宫内膜异位症(EMS)患者(包括36例卵巢子宫内膜异位症和22例子宫腺肌症)的异位内膜和在位内膜及15例子宫肌瘤患者子宫内膜(对照组)中ki-67的表达情况,以增殖指数为统计指标。结果卵巢EMS组和子宫腺肌症的在位和异位内膜ki-67的表达差异均无显著性;对照组子宫内膜和EMS组在位内膜的腺体和间质的ki-67表达在增生期均显著高于分泌期,EMS异位内膜增殖指数在增生期和分泌期差异无显著性(P>0.05);EMS异位内膜ki-67增殖指数在增殖期低于在位内膜,但在分泌期则显著高于在位内膜(P<0.01);EMS异位内膜腺体Ⅰ~Ⅱ期时的ki-67表达高于Ⅲ、Ⅳ期,但在位内膜的ki-67表达在不同临床分期中差异无显著性(P>0.05)。结论ki-67增殖指数反映了子宫内膜细胞的增殖活性,EMS异位内膜细胞持续增殖活跃可能在子宫内膜异位症发生发展中起重要作用。
