项目摘要

Abstract Asian American women experience more favorable cancer survival than other US racial/ethnic groups, even after accounting for known prognostic indicators. Breast cancer, which follows this pattern, is a useful model for understanding factors contributing to this intriguing survival advantage, given that it is the most common cancer in Asian American women, and has established clinical, biological/genetic, and lifestyle prognostic factors. Thus, studying the breast cancer survival advantage in Asian American women has the potential to identify protective factors that may benefit all patients. We propose to investigate multilevel factors (health behaviors and contextual factors, clinical characteristics, treatment, and tumor immune response) in relation to overall and breast cancer-specific mortality in Asian American breast cancer cases. However, the Asian American population is heterogeneous, with lifestyle factors and disease risks (e.g., breast cancer survival rates) varying by specific ethnicity and by immigration status. Many studies have shown the importance of population disaggregation to uncovering meaningful differences among Asian American ethnic groups, but no single study to date includes adequate Asian American ethnic group population samples. To overcome this limitation, we will conduct the proposed research in integrated data and biospecimens from four established cohort studies enriched with Asian American breast cancer cases. These studies together include 4,219 Asian American patients (1,848 Chinese, 602 Japanese, 1,538 Filipinas) and 5,386 non-Latina White women with breast cancer as a comparison group. In Specific Aim 1, we will assess contributions of individual-level lifestyle and health behaviors and multilevel neighborhood social context and sociocultural factors to survival differences among the Asian American ethnic groups relative to non-Latina Whites. In Specific Aim 2, we will evaluate how specific treatment factors impact survival for 4,373 Asian Americans compared to 4,373 non- Latina Whites, taking advantage of electronic health record data from an equal-access healthcare system. In Specific Aim 3, we will characterize the immune infiltrates in the breast tumor microenvironment from 1,200 Asian American (from Aim 1) and 714 non-Latina White (from TCGA) patients using immunogenomic profiling, and to determine the associations of immune phenotypes with patient survival among Asian Americans and with exposure factors from Aim 1. Thus, using existing resources, this study will comprehensively assess factors including health behaviors and neighborhood context, lifestyle, treatment, tumor immuno-biology, and their contributions to the survival advantage in Asian American women. The proposed study makes efficient use of data from numerous breast cancer studies to gain insight for strategies that may advance knowledge about the management of breast cancer for all women.

抽象的亚裔美国妇女的癌症生存比其他美国种族/民族群体更有利，甚至考虑到已知的预后指标之后。遵循这种模式的乳腺癌是一个有用的模型理解有助于这一有趣的生存优势的因素，鉴于它是最常见的亚裔妇女的癌症，并建立了临床，生物学/遗传和生活方式的预后因素。因此，研究亚裔美国妇女的乳腺癌生存优势有可能确定可能使所有患者受益的保护因素。我们建议研究多层次因素（健康行为和情境因素，临床特征，治疗和肿瘤免疫反应）亚裔美国乳腺癌病例的总体和乳腺癌特异性死亡率。但是，亚洲美国人口是异质的，有生活方式因素和疾病风险（例如乳腺癌存活费率）因特定种族和移民身份而异。许多研究表明了人口分解以发现亚裔美国族裔之间有意义的差异，但没有迄今为止，单一研究包括足够的亚裔美国族裔人口样本。克服这一点限制，我们将对四个已建立的综合数据和生物测量进行拟议的研究队列研究富含亚裔美国乳腺癌病例。这些研究一起包括4,219个亚洲美国患者（1,848名中国人，602个日语，1,538名菲律宾人）和5,386名非拉丁裔白人妇女乳腺癌作为比较组。在特定目标1中，我们将评估个人级生活方式的贡献以及健康行为以及多层次的社会社会环境和社会文化因素生存亚裔美国族裔之间的差异相对于非拉丁裔白人。在特定的目标2中，我们将评估特定治疗因素如何影响4,373名亚裔美国人的生存率，而4,373个非 - 拉丁裔白人，利用了从同等访问的医疗保健系统中的电子健康记录数据。在特定的目标3，我们将表征来自1,200的乳腺肿瘤微环境中的免疫浸润。亚裔美国人（来自AIM 1）和714名非latina白人（来自TCGA）患者，使用免疫基因组学分析，并确定免疫表型与亚裔美国人和患者生存的关联通过AIM 1的暴露因素。因此，使用现有资源，本研究将全面评估包括健康行为和邻里环境，生活方式，治疗，肿瘤免疫生物学以及他们对亚裔美国妇女的生存优势的贡献。拟议的研究提高了利用来自众多乳腺癌研究的数据，以了解可能提高知识的策略关于所有女性乳腺癌的管理。
