Biometry Web Projects-Cancer Data Access System (CDAS)

CDAS是一个基于网络的提交和跟踪系统，用于使用来自国家肺筛查试验(NLST)和前列腺癌、肺癌、结直肠癌和卵巢癌(PLCO)筛查试验的数据。感兴趣的调查人员可以向CDAS注册，并请求访问任何一项筛查试验的数据。所有请求都由NCI审判领导层审查。一旦获得批准，调查人员将被允许在有限的时间内访问所请求的数据。CDAS为每项试验提供了广泛的文件，包括试验总结、收集的数据说明以及研究项目和出版物的可搜索清单。 CDAS的长期目标包括整合其他癌症筛查试验的数据，如LSS可行性研究、髋部乳腺癌筛查试验、明尼苏达州粪便潜血筛查试验和梅奥肺癌筛查试验。

CDAS is a web-based submission and tracking system for the use of data from the National Lung Screening Trial (NLST) and the Prostate, Lung, Colorectal and Ovarian (PLCO) Cancer Screening Trial. Interested investigators can register with CDAS and request access to data from either screening trial. All requests are reviewed by NCI trial leadership. Upon approval, investigators are granted access to the requested data for a limited period. CDAS provides extensive documentation for each trial including a summary of the trial, a description of the data collected, and a searchable list of research projects and publications. Long term objectives for CDAS include integration of data from other cancer screening trials such as the LSS Feasibility Study, the HIP Breast Cancer Screening Trial, the Minnesota Fecal Occult Blood Screening Trial, and the Mayo Lung Cancer Screening Trial.
