Diabetes Care:二甲双胍与膀胱癌发病降低无关

2014-02-10 晓静 编译 医学论坛网

美国一项研究表明,二甲双胍与膀胱癌发病率降低无相关性。研究者建议,应用与该研究相同的方法去研究之前报道的二甲双胍对其他癌症的潜在预防作用。文章2月4日在线发表于《糖尿病护理》(Diabetes Care)杂志。 既往评估二甲双胍对癌症风险影响的研究受时间相关偏差的影响,为避免这些偏差,研究者在二甲双胍和磺脲类降糖药(SUs)的起始应用者中评估了膀胱癌的发病率。 该队列研究纳入健康改善网

既往评估二甲双胍对癌症风险影响的研究受时间相关偏差的影响,为避免这些偏差,研究者在二甲双胍和磺脲类降糖药(SUs)的起始应用者中评估了膀胱癌的发病率。

该队列研究纳入健康改善网络数据库的87600例2型糖尿病患者,使用二甲双胍或SU被视为一个随时间变化的变量。校正年龄、性别、吸烟、肥胖和糖化血红蛋白(HbA1c)水平后,利用Cox回归分析二甲双胍和SU的危险比值(HRs)。

结果显示,在二甲双胍和SU队列里分别确诊196和66例膀胱癌患者。应用二甲双胍与膀胱癌风险降低无关(HR 0.81),按性别划分这一相关性也无差异(P趋势为0.20)。相对于SU的应用,研究者们也观察到这一风险与二甲双胍持续应用时间无关(应用3—4 年:0.57;4 —5 年:0.93;≥5 年:1.18;P趋势 0.26)。
