摘要:

目的 探讨多发子宫内膜息肉(EP)和单发EP患者息肉组织中雌激素受体(ER)、血管内皮生长因子(VEGF)和转化生长因子β1(TGF-β1)的表达水平,并分析其与预后的关系。方法 选取行宫腔镜手术治疗的育龄期EP患者100例,其中多发EP(>5个)和单发EP各50例,以因输卵管因素行宫腔镜检查的患者35例作为正常内膜组,采用免疫组化法和逆转录聚合酶链反应(RT-PCR)检测ER、VEGF和TGF-β1在正常子宫内膜组织和单发EP、多发EP组织中的表达量。采用Kaplan-Meier曲线分析EP患者的复发率。采用Cox回归分析评估EP的复发风险。结果 多发EP组和单发EP组息肉组织中ERVEGFTGF-β1 mRNA及蛋白的相对表达量均高于正常内膜组的子宫内膜组织(P<0.05),且多发EP组均高于单发EP组(P<0.05)。多发EP组复发率(42.0%)明显高于单发EP组(12.0%)(P=0.001)。Cox回归分析结果显示,合并子宫内膜异位症[风险比率(HR)=2.718,95%可信区间(CI) 1.179~6.262]和EP多发(HR=4.134,95%CI 1.663~10.273)是EP复发的独立危险因素,VEGF(HR=1.073,95%CI 1.014~1.136)和TGF-β1(HR=1.056,95%CI 1.005~1.109)高表达是多发EP患者复发的独立危险因素。结论 多发EP患者息肉组织中ER、VEGF和TGF-β1高表达与术后高复发率密切相关。

Abstract:

Objective To investigate the expression levels of estrogen receptor (ER),vascular endothelial growth factor (VEGF)and transforming growth factor-beta 1(TGF-β1)in multiple endometrial polyp(EP)and single EP patients,and to analyze the relationship with prognosis. Methods A total of 100 premenopausal women undergoing hysteroscopic endometrial polypectomy were recruited. Among them,there were 50 multiple EP (>5) patients and 50 single EP patients. Totally,35 patients undergoing hysteroscopy due to oviductal problem were enrolled as normal endometrium group. Immunohistochemistry and reverse transcription polymerase chain reaction (RT-PCR) were used to determine the expression levels of ER,VEGF and TGF-β1 in normal endometrium,single EP and multiple EP groups. Kaplan-Meier curve was used to analyze the recurrence rate of EP patients. Cox regression analysis was used to assess the risk of EP recurrence. Results The mRNA and protein expression levels of ER,VEGF and TGF-β1 in the polyp tissues of multiple EP group and single EP group were higher than those in normal endometrium group (P<0.05),and they were higher in multiple EP group than those in single EP group (P<0.05). The recurrence rate in multiple EP group (42.0%) was higher than that in single EP group (12.0%) (P=0.001). Cox regression analysis showed that endometriosis [hazard ratio(HR)=2.718,95% confidence interval(CI) 1.179-6.262] and multiple EP (HR=4.134,95%CI 1.663-10.273) were independent risk factors for EP recurrence,and the high expressions of VEGF (HR=1.073, 95%CI 1.014-1.136) and TGF-β1 (HR=1.056,95%CI 1.005-1.109)were independent risk factors for recurrence in multiple EP patients. Conclusions The high expressions of ER,VEGF and TGF-β1 in multiple EP group are closely related to the high recurrence rate after operation.
