Abstract PFAS are a class of man-made organofluorine compounds whose presence in the environment is an emerging, worldwide public health concern and a priority in environmental and human health research. Many PFAS are environmentally persistent, bioaccumulative, and have long half-lives in humans. Of particular concern is that environmental exposure to PFAS may increase the risk of kidney cancer, whose incidence has shown unexplained sustained and rapid increases in the US during the past decades. Several lines of emerging evidence strongly support that PFAS exposures may increase the risk of kidney cancer among humans: First, the kidney is a target organ of PFAS, which cause serious damage to the kidney at the levels commonly experienced by US population; Second, PFAS exposures have been associated with kidney damage that is known to increase kidney cancer risk; Third, a recent population-based case-control study of 324 RCC cases and 324 controls from NCI supports the findings of early occupational mortality studies that PFAS exposure increases kidney cancer risk. Much larger prospective studies of diverse, non-occupationally exposed populations are urgently needed to either confirm or refute these preliminary findings. Here, we propose a prospective nested case-control study to test the association between PFAS exposure and renal cell carcinoma (RCC, more than 85% of all cases of kidney cancer). We will utilize the extensive resources from five large and well-characterized US prospective cohorts: The Southern Community Cohort Study; Hispanic Community Health Study/Study of Latinos Cohort; Nurses’ Health Study; Health Professionals Follow-Up Study; and Physicians' Health Study. We will measure pre-diagnostic plasma levels of 40 PFAS from ~650 incident RCC cases and their individually matched controls (~1,300 controls in 1:2 ratio). Specifically, we will examine the following hypotheses: 1. Environmental exposure to PFAS increases the risk of RCC. In particular, environmental exposure to PFOA, PFOS and PFHxS increases RCC risk; 2. Risk of RCC associated with environmental PFAS exposure varies by mixture patterns, and varies by PFAS chemical structure, branched vs linear isomers, and short vs. long chain length; and 3. Established baseline risk factors of RCC (hypertension, obesity, diabetes and smoking) moderate the relationship between PFAS exposure and risk of RCC. In exploratory aims, we will test if the risk of RCC associated with individual PFAS exposures varies by histologic type of RCC or by race, and thus may contribute to racial disparities in kidney cancer risk. This proposed study fills a critical knowledge gap and represents the first large prospective cohort study to investigate the alleged association between PFAS exposure and kidney cancer risk in the US among diverse cohorts of non-occupationally exposed individuals. The results of the study will inform the medical and public health communities about the potential health effects of PFAS exposure and can help regulators make sound, science-based decisions.

摘要PFAS是一类人工合成的有机氟化合物， 新出现的全球公共卫生问题，以及环境和人类健康研究的优先事项。许多 全氟辛烷磺酸具有环境持久性、生物累积性，在人体内的半衰期较长。特别关注的 PFAS的环境暴露可能会增加患肾癌的风险，其发病率已显示 在过去的几十年里，美国的人口持续快速增长。几条新兴的 有证据强烈支持PFAS暴露可能增加人类患肾癌的风险：首先， 肾脏是PFAS的靶器官，PFAS在通常水平下可对肾脏造成严重损害 第二，PFAS暴露与肾脏损伤相关， 已知会增加肾癌风险;第三，最近对324例RCC病例进行的基于人群的病例对照研究 来自NCI的324名对照支持早期职业死亡率研究的结果， 增加患肾癌的风险。更大规模的前瞻性研究， 人们迫切需要证实或反驳这些初步调查结果。 在这里，我们提出了一项前瞻性巢式病例对照研究，以测试PFAS暴露与 肾细胞癌（RCC，超过所有肾癌病例的85%）。我们将利用广泛的资源 来自五个大型且特征良好的美国前瞻性队列：南方社区队列研究; 西班牙裔 社区健康研究/拉丁裔队列研究; 护士健康研究;卫生专业人员随访研究; 医生的健康研究我们将测量约650例患者的40 PFAS诊断前血浆水平 RCC病例及其单独匹配的对照（约1，300名对照，比例为1：2）。具体来说，我们将研究 以下假设：1. PFAS的环境暴露会增加RCC的风险。特别是， 环境暴露于PFOA、PFOS和PFHxS会增加RCC风险; 2. RCC的风险与 环境PFAS暴露因混合物模式而异，并因PFAS化学结构而异， 支链与直链异构体，以及短链与长链长度;以及3.确定的基线风险因素 RCC（高血压、肥胖、糖尿病和吸烟）与PFAS暴露的中度关系 和RCC的风险。在探索性目的中，我们将测试RCC的风险是否与个体PFAS相关， 暴露因RCC的组织学类型或种族而异，因此可能导致RCC的种族差异。 肾癌风险。这项拟议的研究填补了一个关键的知识空白，代表了第一个大的前瞻性 队列研究，旨在调查美国PFAS暴露与肾癌风险之间的相关性 在不同的非职业暴露人群中。研究结果将告知医学界 和公共卫生界了解PFAS暴露的潜在健康影响，并可以帮助监管机构 合理科学的决定
