Uploaded caDSR Community Released CDEs as of March 5, 2018
The NCI caDSR CDE Browser can be used to download collections of metadata describing data held in repositories for cancer research and clinical trials. There are currently no NCI Recommended CDEs for use other than the CDEs marked as having a Registration Status of "Standard". Any CDE in caDSR can be reused, but the ones marked "Standard" have been through a broader governance process. There communities within NCI who have agreed to use a set of CDEs for specific purposes, for example EDRN, TCGA, NCTN, and many others. If you wish to collect data that is compatible with a specific group, you should begin by looking for the group's CDEs using the CDE Browser. The Context name is an organizing principle for tree based navigation, and the "Advanced Search" provides a way to search for CDEs grouped by Classifications, or keywords.
Best Practices for creating CDEs can be found here.
The caDSR Form Builder can be used to create, view and download the Case Report Forms (CRFs) designs.

The NCI Preferred Standard CDEs represent those that have been through the NCI's Content Owners Governance and have been determined to meet all the necessary criteria for standardization based on NCI Best Practices. When looking for NCI recommended CDEs, this is the place to start. The attached files are for downloading, a web browser view for comparing or viewing details of these CDEs is available by visiting the CDE Browser and clicking on the "NCI Standards" Context, or by performing an Advanced Search, selecting Registration Status = "Preferred Standard".
Other reusable CDEs can be found by searching using the CDE Browser if you do not find CDEs in the Preferred Standard set that meet your needs. The community standard CDEs have Registration Status = "Standard", and sort to the top of the search results by default, right after "Preferred Standard" For more information about Content development at NCI, see caDSR Content.
For current list of all NCI Standards since the date of this download, visit the NCI caDSR CDE Browser and click "Advanced Search", select "Preferred Standard" Registration Status, select "Search".
