DACH1在子宫内膜癌的表达及与ER、PR表达的相关性

目的:探讨细胞命运决定因子DACH1蛋白、ER、PR在子宫内膜癌的表达及分析其与子宫内膜癌临床病理指标及预后的关系。方法:免疫组化技术检测80例子宫内膜癌、20例正常子宫内膜、10例复杂增生子宫内膜和10例不典型增生子宫内膜组织标本中DACH1蛋白、ER、PR的表达,分析其与子宫内膜癌患者临床病理参数及预后的关系。结果:在子宫内膜癌、正常子宫内膜、不典型增生和复杂增生子宫内膜中DACH1蛋白表达的阳性率分别为36.3%(29/80)、95.0%(19/20)、8/10、10/10,DACH1蛋白在子宫内膜癌中的表达显著低于非癌组(P=0.000)。DACH1表达阳性率内膜癌Ⅰ期为47.7%,Ⅱ~Ⅳ期为22.2%,两者差异有统计学意义(P0.05)。DACH1表达阳性率与内膜癌的病理分级有关,G1~G2级显著高于G3级(43.6%vs 20.0%,P0.05)。内膜样癌中DACH1表达阳性率为42.2%,特殊类型癌中DACH1表达的阳性率为2/16,两者差异有统计学意义(P0.05)。单因素生存分析显示DACH1阳性组子宫内膜癌患者的总体生存率明显高于DACH1阴性组(P0.05)。80例子宫内膜癌组织中34例呈ER阳性表达,42例呈PR阳性表达,DACH1蛋白表达与ER蛋白表达呈正相关(ρ=0.245906,P0.05),与PR蛋白表达呈正相关(ρ=0.3527758,P0.01)。结论:DACH1蛋白在子宫内膜癌组织表达缺失,且和ER、PR表达有一定的相关性,它在子宫内膜癌的发生、发展及预后中可能起重要作用。

The significance of DACH1 expression and it's correlation with the expression of ER and PR in endometrium carcinoma

Objective:To investigate the expressions of cell fatedetermination factor DACH1,ER and PR in endometrial carcinoma tissues,the relationship between DACH1 and the clinicopathological parameters and prognosis of endometrial carcinoma.Methods:The expressions of DACH1,ER and PR were detected by immunostainings in tissues from 80 endometrial carcinomas,20 normal endometrium,10 complex hyperplasia endometrium and 10 atypical hyperplasia endometrium and the relationship with the clinicopathological and prognosis o...
