摘要 目的研究胰腺癌、癌旁组织、正常胰腺组织中DNA损伤修复蛋白ERCC1,RRM1表达及其临床意义。方法选取吉林大学第一医院2009年1月至2012年6月手术切除胰腺癌及癌旁组织34例,正常胰腺组织20例,标本经常规石蜡包埋,采用SABC法行免疫组化染色。结果在胰腺癌组织中ERCC1高表达14例(41.2%),RRM1高表达10例(29.4%),癌旁组高表达率分别为67.6%、52.9%,正常胰腺组织分别为70.0%、80.0%。两种基因的高表达率均低于癌旁组及正常胰腺组(P<0.05)。在有无淋巴结、肿瘤大小、分化程度因素中分析ERCC1及RRM1的高低表达无统计学差异。结论 ERCC1及RRM1基因的表达缺失与肿瘤的发生密切相关,其表达与否对肿瘤大小、分化程度、区域淋巴结转移等无显著影响。
