摘 要: | 目的:研究p53基因突变在非霍奇金淋巴瘤(NHL)发生发展中的作用。方法:在37例非霍奇金淋巴瘤组织中采用PCR-单链构象多态性分析法(PCR-SSCP)进行p53基因外显子5~8的突变检测。结果:p53基因总突变率为54.1%,惰性组、侵袭性组、高侵袭性组突变率分别为0.0%、58.1%、100.0%;T和NK细胞组和B细胞组突变率分别为37.5%、58.6%。结论:非霍奇金淋巴瘤中存在p53基因的突变,p53基因的突变在NHL的发展演变中可能起重要作用。

Abstract: | Objective:To evaluate the mutation of p53 gene in pathogenesis of non-Hodgkin's lymphoma.Methods:Thirty-seven cases of non-Hodgkin's lymphoma were studied for frequency of p53 gene mutation in exon 5 to 8 with PCR-SSCP method.Results:In 37 cases of non-Hodgkin's lymphoma,the frequency of p53 genic mutation was 54.1%.The the frequency of p53 genic mutation was detected in indolent(0.0%),aggressive(58.6%) and highly aggressive group(100.0%).The incidence of p53 genic mutation in T/NK cell lymphoma and B cell lymphoma was 37.5% and 58.6%,respectively.Conclusion:The mutation of p53 gene is present in NHL.Mutation of p53 gene might play a key role in pathogenesis and progression of lymphoma. |
