摘要 [目的]探讨参与生物节律调控的生物钟PER3基因多态性与乳腺癌易感性的关系。[方法]2005年9月至2008年2月,836例乳腺癌患者和946名健康对照者,采用PCR技术对PER3基因多态性进行检测,分析两组PER3基因型的分布及PER3基因多态性与乳腺癌发病风险的关系。[结果]对照组PER3-/-、+/+和+/-基因型分布频率分别为72.73%、1.59%和25.69%,病例组分别为72.61%、1.79%和25.60%,两组分布差异无统计学意义(P=0.9432)。经相关因素调整后,PER3基因型与乳腺癌发病风险相关性分析显示,携带PER3+/+基因型发生乳腺癌的危险是携带PER3-/-基因型的3.503倍(95%CI:1.069~11.480),是携带PER3+/-或PER3-/-基因型对象的3.337倍(95%CI:1.025~10.864)。[结论]PER3+/+基因型能够增加乳腺癌的发病风险,是乳腺癌发生的独立危险因素。
