腹壁内膜异位症在位及异位内膜雌激素受体的表达

采用免疫组化方法 ,对56例腹壁内膜异位症(AWE)患者(增殖期33例,分泌期23例)在位、异位子宫内膜,正常分泌期与增殖期(36与37例)子宫内膜的雌激素受体(ER)蛋白进行测定.AWE患者增殖期组在位内膜ER表达率(85%)高于正常内膜(60%)和异位内膜(58%)(P<0.05);分泌期异位内膜ER表达率(57%)高于在位内膜(26%)和正常内膜(25%)(P<0.05).分泌期在位和正常内膜ER表达率均低于增殖期组(P<0.01),异位内膜ER表达率差异无统计学意义.在位和异位内膜ER的异常表达可能与AWE的发生有关.

Expression of estrogen receptor in entopic and ectopic endometrium of abdominal wall endometriosis

Fifty-six patients with abdominal wall endometriosis(AWE)were assigned into the proliferous group or the secretory group and the expression of estrogen receptor(ER)in the entopie,ectopic and normal endometrium was investigated.In the proliferous group,the positive ER expression rate on the entopie endometrium(85%)was significantly higher than that on the normal(60%)or ectopie endometrium (58%)(P<0.05).In the secretory group,the positive ER expression rate on the eetopie endometrium (57%)was significantly higher than that on the entopic (26%) or normal endometrium(25%)(P< 0.05).There was significant difference in the entopie and normal endometriilm between the two groups (P<0.01):however,there was no significant diffeFence in the ectopic endometrium.Abnormal ER expression on the entopic or ectopic endometrium may play a role in the pathogenesis of AWE.
