The Statistical Coordinating Center's (SCC) primary functions are to support the collection and analysis of data for the Breast Cancer Surveillance Consortium, develop and implement new statistical methodology that will characterize the process of mammography, and provide scientific guidance in the development of publications. The major goals of the Consortium are to provide population-based information on the performance of breast cancer screening in the community, improve the process of tumor detection, examine the role of practice patterns and biological factors on outcomes, and evaluate the efficacy of mammography in reducing breast cancer morbidity and mortality. In the last four years the SCC has established a standardized data collection system, constructed standardized questions, analyzed 1.5 million mammograms for inclusion in three papers underway, and assessed reader variability in interpretation of mammograms. In the next five years, the SCC will do the following: (1) Implement methods that continue to improve comparability of data across sites by improving quality control and maintaining standardized data collection instruments; (2) Maintain a data management system that facilitates pooled analyses and rapid development of new projects; (3) Conduct analyses of the outcomes of screening and symptomatic mammography to identify predictors and sources of variation across sites; (4) Develop statistical methods that allow for modeling of hierarchical, longitudinal data with covariates at the site, radiologist, or woman level; (5) Develop methods to evaluate the efficacy of the BIRADS 0 (incomplete) on outcomes; (6) Evaluate accuracy in a population undergoing repeat mammography; and (7) Provide scientific leadership and dissemination by maintaining a Consortium Web page, conducting annual meetings of the Data Managers and Statisticians, conducting site visits, and participating in the scientific leadership by developing proposals, conducting analyses, and publishing the results.

统计协调中心（SCC）的主要职能是支持乳腺癌监测联盟的数据收集和分析，开发和实施新的统计方法，以描述乳腺X射线摄影的过程，并在出版物的开发中提供科学指导。 该联盟的主要目标是提供关于社区乳腺癌筛查绩效的基于人口的信息，改进肿瘤检测过程，研究实践模式和生物因素对结果的作用，并评估乳房X线摄影术在降低乳腺癌发病率和死亡率方面的功效。在过去的四年里，SCC建立了一个标准化的数据收集系统，构建了标准化的问题，分析了150万张乳房X线照片，并将其纳入正在进行的三篇论文中，并评估了读者在解读乳房X线照片时的差异。 在今后五年中，统计委员会将开展以下工作：（1）通过改进质量控制和维护标准化数据收集工具，采用各种方法，继续提高各地点数据的可比性;（2）维护一个数据管理系统，以促进汇总分析和快速开发新项目;（3）对筛查和症状性乳房X线摄影的结果进行分析，以确定预测因素和不同地点的变异来源;（4）开发统计方法，允许在研究中心、放射科医生或女性水平上使用协变量对分层纵向数据进行建模;（5）开发评估BIRADS疗效的方法0（6）评价重复乳房X线摄影人群的准确性;以及（7）通过维护联盟网页、举行数据管理员和统计员年度会议、进行现场访问以及通过制定提案、进行分析、并公布结果。
