1、甘肃医药 2023 年 42 卷第 6 期Gansu Medical Journal,2023,Vol.42,No.63讨论本研究采用病例对照的方式,采集了 101 例乳腺癌病例作为癌症组,采集 101 例健康人作为对照组。同时,根据世界卫生组织 2012 年对乳腺纤维腺瘤的定义12,乳腺纤维腺瘤为起源于终末导管小叶单位的界限清楚的乳腺肿块,故本课题采集 101 例乳腺纤维腺瘤病例同时设为对照组。由于健康人组哈代温伯格检测不平衡,未能纳入进一步的数据分析,因此本课题将乳腺纤维腺瘤病例作为对照组。关于 rs3176658 多态性与肿瘤易感性关系的研究较少。Annah 等报告 rs3176658
2、位点 SNPs 与头颈癌易感性无相关13;Doherty 等报告 rs3176658 位点 SNPs 总体上与子宫内膜癌易感性无相关,但是在“高风险”妇女组(指连续使用雌激素 6 个月以上),rs3176658 位点SNPs 与子宫内膜癌易感性相关(未提供详细数据)14;Lori 等报告 rs3176658 位点 SNPs 与肺癌的易感性相关,且女性中较男性更为明显15。本课题对于 XPA 基因 rs3176658 位点 SNPs 与乳腺癌这一病种的易感性进行了研究,报告了 XPA 基因内含子 rs3176658 位点 SNPs 与乳腺癌易感性相关,rs3176658 位点突变型 T/T 增加
