摘要 目的:研究DNA修复基因XRCC1(rs25487)和XRCC3(rs1799796)的单核苷酸多态性与膀胱癌易感性及其病理参数的相关性。方法:采用病例一对照研究方法.收集经病理诊断为膀胱癌患者的279例为病例组,健康体检正常的人群280例为对照组,采用限制性片段长度多态性-聚合酶链式反应(PCR—RFLP)技术检测多态性位点rs25487和rs1799796在病例组和对照组中的基因型分布。采用Logistic回归模型分析各基因型与膀胱癌发生的关系并比较不同基因型与膀胱癌及其病理参数的关系。结果:XRCC1(rs25487)和XRCC3(rs1799796)位点在病例及对照组中分布无统计学差异(均P〉0.05):rs25487的AG基因型在肿瘤分期Ⅰ-Ⅱ期(OR=0.48,95%C1=0.31~0.73)、高分化(OR=0.53,95%CI=0.29~0.97)、低分化(OR=0.56,95%CI=0.33~0.94)、无周围淋巴结转移组(OR=0.53。95%CI=0.34—0.84)、无远端淋巴结转移组(OR=0.56,95%CI=0.37~0.83)中的分布频率低于对照组;rs1799796的GG基因型在中分化(OR=3.68.95%CI=1.62~8-36)、有周围淋巴结转移纽(OR=2.36,95%CI=1.23~4.53)及有远端淋巴结转移组(OR=2.51,95%CI=1.08~5.80)中的分布频率高于对照组,使膀胱癌的发病风险增加。结论:本研究发现XRCC1(rs25487)和XRCC3(rs1799796)与膀胱癌的病理进展相关。
