PROJECT SUMMARY – Biostatistics and Data Management Core The Biostatistics and Data Management (BDM) Core will support all projects and the Comparative Effectiveness (CE) Core by providing centralized coordination of high-quality data collection, management, analysis, and sharing. The BDM Core includes six Breast Cancer Surveillance Consortium (BCSC) breast imaging registries and a central Statistical Coordinating Center (SCC). The core will increase efficiency by providing projects with data collected from a common cohort of women and sharing novel statistical methods performed by a single analytical support team. The specific aims are to: (1) collect, pool, manage, and share high-quality data required to meet project aims; (2) collaborate with program investigators in implementing sound and efficient study designs and perform valid statistical analyses that address each project aim; and (3) develop and implement novel statistical methods needed to meet study aims. The BDM Core will accomplish these aims using existing and new data collected on 2.6 million women (including 90,000 survivors with surveillance imaging) by six breast imaging registries. These BCSC registries have built strong relationships with the participating breast imaging facilities and have established secure procedures for data collection and linkage. Data will be pooled and analyzed by the SCC, which has extensive experience in data management, analyzing complex longitudinal observational data, and developing novel statistical methods as needed to overcome the limitations of existing methods. Following the BCSC's well-established collaborative research policies and procedures, the BDM Core will continue its successes in sharing data with the broader research community. Using the unique set of resources available to the BCSC — the established and cohesive research network; integrated surveillance system of longitudinal, individual-level data on women, radiologists, and facilities; infrastructure for accessing well-characterized study populations; and expertise in statistical methods and outcomes measurement in community settings — the BCSC registries and SCC will continue working together to support this renewal in answering key questions that cannot be addressed otherwise. These combined strengths ideally position the program's research teams to determine the most effective breast cancer screening and surveillance strategies in community practice.

生物统计和数据管理（BDM）核心将通过提供高质量数据收集、管理、分析和共享的集中协调，支持所有项目和比较有效性（CE）核心。BDM核心包括六个乳腺癌监测联盟（BCSC）乳腺成像登记中心和一个中央统计协调中心（SCC）。该核心将通过向项目提供从一个共同的妇女群体收集的数据和分享由一个单一的分析支助小组执行的新的统计方法来提高效率。具体目标是： (1)收集、汇集、管理和共享实现项目目标所需的高质量数据; (2)与项目调查人员合作，实施合理有效的研究设计，并进行有效的统计分析，以解决每个项目的目标; (3)开发和实施新的统计方法，以满足研究目标。 BDM核心将利用六个乳腺成像登记处收集的260万名妇女（包括9万名监测成像的幸存者）的现有和新数据来实现这些目标。这些BCSC登记研究与参与的乳腺成像机构建立了牢固的关系，并建立了数据收集和链接的安全程序。数据将由SCC汇总和分析，SCC在数据管理、分析复杂的纵向观察数据以及根据需要开发新的统计方法以克服现有方法的局限性方面具有丰富的经验。根据BCSC完善的合作研究政策和程序，BDM核心将继续与更广泛的研究界分享数据。利用BCSC现有的一套独特的资源-已建立的和有凝聚力的研究网络;关于妇女、放射科医生和设施的纵向、个人层面数据的综合监测系统;访问特征明确的研究人群的基础设施;以及在社区环境中统计方法和成果衡量方面的专业知识-BCSC登记处和SCC将继续合作，以支持这一更新，回答无法通过其他方式解决的关键问题。这些综合优势使该项目的研究团队能够在社区实践中确定最有效的乳腺癌筛查和监测策略。
