Carolina Breast Cancer Study

The Carolina Breast Cancer Study (CBCS), phase III, is a population-based study aiming to understand the social and molecular correlates of breast cancer outcomes, particularly among Black and young women. CBCS recruited first primary breast cancer cases from 44 North Carolina counties between 2008-2013. All cases were between age 20 and 74 and self-identified as female. Black women and young women were systematically oversampled by randomized recruitment such that the study includes approximately 50% Black women and approximately 50% women diagnosed before age 50.

In the ten years following diagnosis, women completed surveys approximately every 1-2 years and diagnoses of subsequent distant local recurrence and second primary tumors were...

卡罗来纳乳腺癌研究（Carolina Breast Cancer Study, CBCS）第三期是一项基于人群的研究，旨在阐明乳腺癌转归的社会与分子关联因素，尤其聚焦于黑人女性与年轻女性群体。该研究于2008年至2013年间，从北卡罗来纳州44个县招募了首次确诊原发性乳腺癌的病例。所有研究对象年龄介于20至74岁之间，且自我报告为女性。研究通过随机招募方式对黑人女性与年轻女性进行了系统过采样，最终队列中约50%为黑人女性，约50%为50岁前确诊乳腺癌的女性，共计纳入2998名参与者。在确诊后的十年间，研究对象每1至2年完成一次随访调查，同时会记录后续远处局部复发及第二原发肿瘤的诊断情况……（更多详情请参见dbGaP研究页面）
