JAMA Netw open:辅助生殖技术与儿童癌症风险

2022-09-04 liangying MedSci原创

通过ART怀孕的儿童比自然受孕的儿童患癌症的风险更高,且增加的风险不能用早产或出生体重过低来解释。

全世界通过辅助生殖技术(ART)出生的婴儿数量正在逐渐增加,2018年,台湾约每20名新生儿中就有1名在ART的帮助下出生(占所有新生儿的5.7%)。然而,有证据表明,有生育问题或接受不孕治疗的父母所生的孩子,其表观遗传改变和不良围产期结局的风险增加——这些可能与儿童癌症有关。

本研究的目的是确定不同受孕方式与儿童癌症之间的关系,以及早产和出生体重过低的潜在中介作用。

这项全国性、基于人群的队列研究包括2004年1月1日至2017年12月31日台湾2308016名合格父母-儿童三合会的登记数据。共确定了1880名儿童癌症患者。数据分析时间为2020年9月1日至2022年6月30日。

受孕模式,定义为(1)自然受孕,(2)亚生育和非ART(即不孕症诊断但无ART促进受孕),或(3)ART(如不孕症诊断和ART促进的受孕),主要结局是根据国际儿童癌症分类第三版对儿童癌症的诊断。

研究结果发现,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。在1490万人年的随访期间(中位数,6年[IQR,3-10年]),与自然受孕(危险比,1.58;95% CI,1.17-2.12)和非ART受孕的亚生育(危险比:1.42;95% CI,1.04-1.95)相比,ART受孕与任何类型的儿童癌症风险增加相关。接受抗逆转录病毒治疗的儿童患癌症的风险增加主要是由于白血病和肝肿瘤。与ART受孕相关的癌症风险增加不是由早产或低出生体重引起的。

ART受孕、低生育能力和非ART受孕儿童癌症风险的比较

总之,在这项队列研究表明,通过ART怀孕的儿童比自然受孕的儿童患癌症的风险更高,且增加的风险不能用早产或出生体重过低来解释。
