摘要
目的:研究癌基因bcl-2及抑癌基因p53在子宫内膜癌发生、发展中的作用。方法:采用免疫组化ABC法检测49例子宫内膜癌中bcl-2、p53基因蛋白的表达。结果:49例子宫内膜癌中26例bcl-2表达阳性,占53%;12例p53表达阳性,占25%。子宫内膜癌组织学分级G1、G2bcl-2表达率(66%)显著高于G3表达率(21%,P<005),而G3p53表达率(46%)显著高于G1、G2表达率(17%,P<005),bcl-2表达阳性与阴性者生存率统计无显著性差异,p53表达阳性者生存率显著低于p53表达阴性者。bcl-2、p53表达与肌层浸润、手术分期无明显相关。结论:癌基因bcl-2与抑癌基因p53可能在子宫内膜癌发生的不同阶段起作用,抑制细胞凋亡,促进肿瘤的发展与转归。
Objective:To study the overexpression of bcl-2 and p53 in endometrial carcinoma and its relationship to clinicopathological fectures and prognosis.Methods:Overexpression of bcl-2 and p53 were studied by immunohistochemistry ABC method in paraffin-embedded tissues in 49 women with endometrial carcinoma,and X 2 analysis and survival curves were determined by the Kaplan-Meier method.Results:Bcl-2 overexpression was observed in the majority(53%) of endometrial carcinoma,while p53 overexpression was in the minority(25%).Bcl-2 overexpression was found to be significantly higher in FIGO G 1 and G 2 than in G 3 tumors(P<0 05),while inversely,p53 overexpression was significantly higher in FIGO G 3 than in G 1,G 2 tumors(P<0 05).p53 overexpression was related to poor survival rates,while bcl-2 was not.Neither bcl-2 nor p53 overexpression in tumors correlated with invasion and stages.Conclusions:In the development of endometrial carcinoma,bcl-2 oncogene and p53 tumor-suppressor gene may correlate with the progression of the malignant process.
