摘要: 采用改进的aPCR - SSCP 银染技术和SP 免疫组化技术检测36 例卵巢上皮癌,12 例卵巢上皮交界瘤和15 例良性卵巢上皮肿瘤的P53基因的突变和突变蛋白的表达。结果卵巢上皮癌P53基因突变率为30. 6 % ,突变蛋白表达为58. 4 %。P53基因突变主要发生在外显子5~8 上,以第7 外显子突变率最高。交界性肿瘤个别出现P53基因突变和突变蛋白表达,而在良性肿瘤无一例出现。提示P53基因突变是卵巢癌形成过程中的晚期事件。P53基因突变可作为肿瘤标记物判定卵巢癌的预后。aPCR - SSCP 非同位素基因突变技术克服了常规PCR - SSCP 检测方法的缺陷,可提高准确性。

Abstract: To dectect P53gene mutation and it s mutation protein ,improved aPCR - SSCP silver staining and SP immunohistochemical methods were emploied in 12 borderline epithelial ovarian tumor and 15 benign epithelial ovarian tumor. The result s showed that positive rate of P53 gene mutation was 30. 6 % , and that of the mutation protein was 58. 4 %. The mutation of P53 gene was mainly on it s exon 5 - 8 ,especially on exon 7. In some cases of borderline tumor , P53 gene and it s mutation protein were positive , but nine in benign tumor This indicated that P53gene mutation was a later event in the form ovarian carcinoma. P53gene mutation might serve as a genetic marker to determine the prognosis of ovairan carcinoma. aPCR - SSCP sliver staining method overed the defect of former method ,and improved the accuracy of esamine.
