JAMA Netw Open:辅助生殖技术与儿童癌症风险

全世界通过辅助生殖技术(ART)出生的婴儿数量有所增加。在2018年的台湾,每20名新生儿中约有1名是在ART帮助下出生的(占所有新生儿的5.7%)。然而,有生育问题或接受不孕治疗的父母所生的孩子被发现有增加的表观遗传改变和不良围产期结局的风险,可能与儿童癌症有关

目前关于ART受孕与儿童癌症之间关联的证据仍有待商榷。在暴露和结局都是罕见事件的情况下,目前很少有研究使用基于人群的大型设计来减少选择偏倚并避免有限数量的暴露病例。过去的研究没有探讨围产期结局是否介导了受孕方式与儿童癌症之间的关联。因此,本研究使用2004年至2017年间台湾登记数据设计了一项基于人群的队列研究,以检查受孕方式(自然受孕,低生育力和非ART以及ART)与儿童癌症风险的关联,并评估了围产期结局在该关联中的潜在中介作用。

这项基于人群的全省性队列研究包括从2004年1月1日至2017年12月31日台湾2308016名符合条件的亲子三合会的登记数据。共确定了1880名患有儿童癌症的儿童。受孕模式定义为(1)自然受孕,(2)低生育力和非ART(即,不孕症诊断,但没有ART促进受孕),或(3)ART(即不孕不育诊断和ART促进受孕)。

结果显示,父亲和母亲的平均年龄分别为33.28(5.07)和30.83(4.56)岁。在2308016名儿童中,52.06%为男孩,8.16%为早产儿,7.38%为低出生体重儿。

父亲和母亲的平均(SD)年龄分别为33.28(5.07)和30.83(4.56)岁。2308016例中,52.06%为男孩,8.16%为早产,7.38%为低出生体重儿。在1490万人年的随访中(中位数,6年[IQR, 3-10年]),在对混杂因素进行调整后,与自然受孕相比,ART受孕与任何类型的儿童癌症(HR,1.58;95%CI,1.17-2.12),白血病(HR,2.10;95%CI,1.20-3.70)和肝肿瘤(HR,2.71;95%CI,1.28-5.73)的风险增加有关。与未接受ART的不孕不育相比,ART受孕还与任何类型的儿童癌症(HR,1.42;95%CI,1.04-1.95),白血病(HR,1.88;95%CI,1.03-3.43)和肝肿瘤(HR,2.41;95%CI,1.05-5.52)的风险较高相关。其他类型的儿童癌症与受孕方式没有关联。儿童癌症的风险在低生育力和非ART受孕组与自然受孕组之间没有显着差异。

中介分析表明,与ART受孕相关的癌症风险增加不是由早产或出生体重过低介导的。

在这项队列研究中,通过ART受孕的儿童患儿童癌症的风险高于自然受孕的儿童,并且高于那些被诊断为不孕症的父母所生的孩子没有使用ART。风险增加不能用早产或低出生体重来解释。
