1、昆明医科大学学报2013,(6):82~84CN53—1221/RJournalofKunmingMedicalUniversity非小细胞肺癌XRCC1Arg399GIn基因分析与顺铂疗效的关系李恒,黄云超,冯雨(昆明医科大学第三附属医院,云南省肿瘤医院,云南昆明650118)[摘要]目的探讨x线修复交叉互补基因1(x—rayrepairClOgScomplementinggroup1,XRCC1)Arg399Gln基因多态性分析与顺铂疗效的相关性.方法回顾性分析83例接受以Nef为主的联合化疗非d,-N胞肺癌(non—fwallce11lungcancer,NSCLC)患者的治疗效果.
2、应用多聚酶链反应一限制性片段长度(polymerasechainreac~LOllrestrictionfragmentlen舢p~mowhism,PCR-一RFLP)法分析XRCC1Arg399Gln的多态性,并对两者关系进行分析.结果携带XRCC1399Arg/Arg基因型患者49例(59.04%),携带Arg,Gin基因型28例(33.73%),携带Gin/Gin基因型6例(7.23%).在XRCC1399Arg/Arg、Arg/Gln和Gin/Gin携带者中,化疗有效率分别为42.86%、11.2%和19.3%.A,A组化疗有效率优于A/G+G/G(42.86%vsl1.76%),
3、P<0.05.Gln等位基因携带者的疗效不如Arg等位基因携带者.XRCC1基因型与化疗毒副反应的发生没有明显相关性.结论xRcc1Arg399Gln基因分型与顺铂疗效有一定关系,其中携带XRCC1399Arg/Arg患者更有利于使用顺铂,可以为临床用药提供一定的依据.[关键词]非小细胞肺癌;xRcC1Arg399Gln;顺铂;疗效[中图分类号]R734.2[文献标识码]A[文章编号]2095-610X(2013)06—0082—03AssociationbetweenXRCC1Arg399GInPolymorphismsinNon-smallCellLungCancerwithEfica
