Commentary: No multiplicative GXE interactions for breast cancer risk: Have we reached a verdict or is the jury still out?

In this issue of the IJE, Kapoor et al.1 report findings from the most comprehensive breast cancer (BC) study to date evaluating gene–environment (GXE) interactions, with 205 BC susceptibility genes and 13 established BC risk factors. With both its size and scope, this study provides evidence specific to the evaluation of the potential use of GXE interactions in risk models and for considering potential aetiologic mechanisms. The study used data from the Breast Cancer Association Consortium (BCAC) and assessed genetic variants with two platforms—iCOGS (28 176 cases and 32 209 controls) and OncoArray (44 109 cases and 48 145 controls). The OncoArray platform has ∼2.5 times the coverage of single nucleotide polymorphisms (SNPs), with 533 000 SNPs compared with 211 155 SNPs on iCOGS. The investigators performed analyses separately by platform and then combined data using meta-analytic techniques. Specifically, they examined interactions with age at menarche, parity (ever, number and age at first birth), breastfeeding (ever and overall duration), ever use of oral contraceptives, body mass index (BMI), adult height, lifetime alcohol consumption, cigarette smoking (current and overall pack-years based on duration and intensity) and menopausal hormone therapy (MHT, opposed and unopposed). The key finding was an overall lack of multiplicative GXE interactions with established BC risk factors with few exceptions.

评论:乳腺癌风险没有可乘的GXE相互作用:我们是否已作出判决或陪审团仍在进行中?

在IJE的这一期中,Kapoor等人。1个报告了迄今为止最全面的乳腺癌(BC)研究的结果,该研究评估了205个BC易感基因和13个已确定的BC危险因素,从而评估了基因与环境(GXE)的相互作用。就其规模和范围而言,本研究为评估风险模型中GXE相互作用的潜在用途以及考虑潜在的病因机制提供了具体证据。该研究使用了来自乳腺癌协会协会(BCAC)的数据,并通过两种平台评估了遗传变异:iCOGS(28 176例和32 209例对照)和OncoArray(44 109例和48 145例对照)。OncoArray平台的单核苷酸多态性(SNP)覆盖率约为2.5倍,有533 000个SNP,而iCOGS则为211 155个SNP。研究人员通过平台分别进行了分析,然后使用荟萃分析技术对数据进行了合并。具体来说,他们研究了与初潮年龄,胎次(曾经,第一次出生的人数和年龄),母乳喂养(曾经和总体持续时间),曾经使用口服避孕药,体重指数(BMI),成人身高,终生饮酒,吸烟(根据持续时间和强度,当前和整个包年)和更年期激素疗法(对立和不对立的MHT)。关键发现是,除了几乎没有例外,总体上缺乏与已确定的BC危险因素的乘性GXE相互作用。成人身高,一生中的饮酒量,吸烟(根据持续时间和强度,当前和整个包装年)和更年期激素疗法(MHT,反对和反对)。关键发现是,除了几乎没有例外,总体上缺乏与已确定的BC危险因素的乘性GXE相互作用。成人身高,一生中的饮酒量,吸烟(根据持续时间和强度,当前和整个包装年)和更年期激素疗法(MHT,反对和反对)。关键发现是,除了几乎没有例外,总体上缺乏与已确定的BC危险因素的乘性GXE相互作用。
