近日,在医学权威杂志JAMA上面发表了一篇研究文章,研究人员在调整其他癌症治疗后,探讨雄激素剥夺治疗(ADT)对于前列腺癌患者来说患阿尔兹海默症的相对风险。

方法:
研究对象的年龄均为67岁及以上,研究数据来自于医疗保险索赔数据库中人口统计资料、生存情况、诊断规范、手术规范以及关于医保者的其他信息。研究人员评估了ADT引起的痴呆和AD的未调整或调整的风险。研究人员预先指定生存分析方法为相互竞争的风险回归。

结果:

在2001年至2014年期间,共有120万名医保者患上了前列腺癌,其中35%的人接受了ADT治疗。其中109815例(8.9%)和223765例(18.8%)患者分别出现AD和痴呆,并有26%至33%的人死于其他结局。接受了ADT治疗的患者,其每千名病人年的未调整的AD风险率和全因死亡率较高。每千名病人年未经调整的AD风险率分别为17.0(接受ADT治疗)和15.5(未接受ADT治疗),未经调整的全因死亡率分别为73.0(接受ADT治疗)和51.6(未接受ADT治疗)。未调整的痴呆率分别为38.5(接受ADT治疗)和32.9(未接受ADT治疗),未调整的死亡率分别为60.2(接受ADT治疗)和40.4(未接受ADT治疗)。

然而,研究人员在对其他癌症治疗和其他协变量进行了调整分析后,接受ADT治疗的患者没有增加AD的风险(subdistribution HR:0.98;95% CI:0.97-0.99),痴呆的风险极小(1%)(SHR:1.01;95% CI:1.01-1.02);接受ADT治疗的患者在发展到AD之前更有可能死亡(SHR:1.24;95% CI:1.23-1.24)或痴呆(SHR:1.26;95% CI:1.25-1.26)。AD和痴呆的风险与ADT的持续时间无关,即无剂量效应。其他的二级分析证实了这些结果。

结论:
这些数据表明,对于年龄在67岁或以上的前列腺癌来说,ADT治疗没有增加AD风险,对痴呆症也没有任何有意义的风险。
