荧光原位杂交检测子宫内膜癌8号染色体畸变

Detection of chromosome 8 abnormalities in carcinoma of endometrium (endometrial carcinoma of uterus) by fluorescence in situ hybridization( FISH)

目的:探讨第8号染色体改变与子宫内膜癌发生、发展及预后的关系。方法:应用荧光原位杂交技术(fluorescence in situ hybridization,FISH)对子宫内膜癌、子宫内膜增殖症及正常子宫内膜标本各10例进行第8号染色体检测研究。结果:本组10例子宫内膜癌第8号染色体出现单体、3体或4体畸变,畸变率100％(10/10);子宫内膜增殖症第8号染色体出现单体、3体畸变,畸变率70％(7/10);正常子宫内膜第8号染色体无畸变,子宫内膜癌与子宫内膜增殖症及正常子宫内膜比较,差异显著。结论:子宫内膜癌第8号染色体畸变,与子宫内膜癌发生、发展密切相关,其改变发生在子宫内膜癌早期,与患者临床分期、病理分化相关。

Purpose: To study the relationship between chromosome abnormalities and the pathogenesis, development and prognosis of endometrial carcinoma of uterus. Methods: FISH was used to detect endometrial carcinoma, endometrial hyperplasia and normal endometrium , 10 cases in each group, respectively. Results: All of the 10 carcinoma cases had chromosome 8 mutation, including trisomy, monosomy, tetraploid and in 10 cases of endometrial hyperplasia with trisomy of chromosome 8 were found. But there were no mutations of chromosome 8 in the normal group. There was significant difference in the three groups. Conclusions: Abnormalities of chromosome 8 are significantly associated with the process of pathogenesis, development of endometrial carcinoma. The abnormalities may occur in the early stage of the carcinoma, and may have the significant association with clinical stage and pathological differentiation among the patients.
