PROJECT SUMMARY Early onset breast cancer (BC) incidence has increased dramatically worldwide, including in the U.S. where the greatest increase has occurred in young non-Hispanic Black (NHB) women. Identifying the modifiable causes of early onset BC is critical for reducing health inequities, a top priority for public health and BC prevention, and addresses one of the NCI’s 2020 provocative questions on the etiology of cancers in adults under age 40. Physical activity in adulthood is an established risk factor for cancer, and the long latency of tumorigenesis suggests that physical activity in adolescence may play an important role in the development of early onset BC. However, there is currently limited epidemiologic data, especially from racially diverse cohorts, to support this. It is essential that we address this major gap in the evidence-base. The overarching goal of this study is to elucidate the role of adolescent physical activity in the risk of and outcomes from early onset BC, including whether physical activity impacts breast tissue biomarkers in adolescent girls and young women. Aim 1 (K99) will evaluate adolescent physical activity in association with early onset BC risk and outcomes after diagnosis in young women across the continuum of BC susceptibility using survival modeling approaches coupled with causal methods, including Mendelian randomization and sibling set analyses. This aim will use existing data from a racially diverse family-based cohort of 31,640 women that is enriched for BC family history (BCFH) and includes 7,703 (1,422 NHB or Hispanic) women diagnosed with BC before age 50 (3,108 diagnosed before age 40). Aim 2 (K99) will determine if physical activity is associated with intermediate markers of BC risk in adolescent girls, including timing of breast development and breast tissue composition (BTC) measured by optical spectroscopy (OS). This aim will use existing prospective data from two adolescent cohorts, including a multiethnic cohort of 1,040 girls that is enriched for BCFH and a cohort of 216 NHB and Hispanic girls in NYC. Aim 3 (R00) will evaluate if adolescent physical activity is associated with structural and metabolic differences in the breast tissue of young women under age 40 and determine if these alterations are associated with early onset BC risk. This aim will be completed during the independent R00 phase by conducting a case-control study in 150 women under age 40, newly diagnosed with BC, and 300 matched controls (sample ≥50% NHB or Hispanic). BTC will be measured in cases and controls using OS and mammography. Taken together, this study will provide the most comprehensive evaluation of adolescent physical activity and early onset BC to date, which is needed to move the field of BC prevention research forward in developing novel intervention strategies for populations at increased risk of early onset disease. This research will be complemented by experiential and didactic training in molecular and genetic epidemiology, advanced statistical methods, physical activity research, and intervention design, as well as career development activities. This K99/R00 award will thus facilitate the long-term career objective of leading an independent research program studying modifiers of cancer risk that are amenable to early life intervention.

项目概要 早发性乳腺癌 (BC) 的发病率在全球范围内急剧增加，其中包括美国 增幅最大的是年轻的非西班牙裔黑人 (NHB) 女性。 早发 BC 对于减少健康不平等至关重要，这是公共卫生和 BC 预防的首要任务，并且 解决了 NCI 2020 年关于 40 岁以下成人癌症病因学的挑衅性问题之一。 成年期的体力活动是癌症的既定危险因素，而且肿瘤发生的潜伏期较长 表明青春期的体力活动可能在早发 BC 的发展中发挥重要作用。 然而，目前支持这一点的流行病学数据有限，尤其是来自不同种族群体的数据。 解决证据基础上的这一重大差距至关重要。这项研究的首要目标是阐明这一点。 青少年体力活动在早发 BC 的风险和结果中的作用，是否包括 目标 1 (K99) 将评估身体活动对青春期女孩和年轻女性乳腺组织生物标志物的影响。 青少年体力活动与年轻女性早发 BC 风险和诊断后结果的关系 使用生存建模方法与因果方法相结合，跨越 BC 易感性的连续体， 包括孟德尔随机化和兄弟姐妹集分析，该目标将使用来自不同种族的现有数据。 基于家庭的 31,640 名女性队列，丰富了 BC 家族史 (BCFH)，其中包括 7,703 名 (1,422 NHB 或西班牙裔）在 50 岁之前诊断出患有 BC 的女性（3,108 名在 40 岁之前诊断出）将。 确定体力活动是否与青春期女孩 BC 风险的中间标志相关，包括 通过光谱 (OS) 测量乳房发育时间和乳房组织成分 (BTC)。 Target 将使用两个青少年队列的现有前瞻性数据，其中包括 1,040 名女孩的多种族队列 丰富的 BCFH 和纽约市 216 名 NHB 和西班牙裔女孩的队列将评估是否。 青少年体力活动与青少年乳腺组织的结构和代谢差异有关 40 岁以下的女性，并确定这些改变是否与早发 BC 风险相关。 在独立 R00 阶段通过对 150 名 40 岁以下女性进行病例对照研究完成， 新诊断的 BC 和 300 名匹配的对照（样本≥50% NHB 或西班牙裔）将被测量。 综上所述，本研究将提供最全面的使用 OS 和乳房 X 光检查的病例和对照。 迄今为止对青少年体力活动和早发 BC 的评估，这是推动 BC 领域发展所必需的 预防研究的进展，为早期感染风险增加的人群制定新的干预策略 这项研究将得到分子和遗传学方面的经验和教学培训的补充。 流行病学、先进的统计方法、身体活动研究和干预设计以及职业 因此，该 K99/R00 奖项将促进领导一个长期职业目标。 研究适合早期生命干预的癌症风险调节因素的独立研究项目。
