The CDE Browser can be used to download collections of meta data describing data held in repositories for cancer research and clinical trials. These CDEs can be downloaded in Excel or XML Format. However, it is not always easy to find the desired collection, as the high level organization of CDEs in the Navigation Tree is by Context, not topic. After selecting a Context, one can browse the Classifications, but this may not be intuitive to some users.

Additionally, attempting to download all the caDSR CDEs would result in a file that is too large for a single MS Excel download.

Therefore, "canned", or pre-downloaded collections in the following CDEs are provided for your convenience.

NCI Standard CDEs

caDSR Community Released CDEs

REDx - caDSR REDCap Transformation Utilities

Current NCI Standard CRFs

The NCI develops and publishes standard CRF templates for use in creating new clinical trials protocol forms.  Each CRFs consists of CDEs organized into 3 sections: mandatory, optional, and conditional CDEs. To retrieve these and any other forms registered in caDSR since the dates listed below, please visit the caDSR Form Builder

 Project CDEs

For other prior versions of the files see the Attachments listed at the end of this page.

If importing caDSR content into another ISO/IEC 11179 registry, i.e. local implementation of cgMDR, please add the caDSR Registration Authority Identifier (RAI) 2.16.840.1.113883.3.26.2 to the metadata to keep the caDSR content distinct from the local repository. Per ISO/IEC 11179, the RAI is part of a globally unique identifier known as the IRID (Item Registry Identifier), and uniquely identifies registry content as being related to particular registrars. The IRID for all caDSR content is the <caDSR OID + Item public Id + item version>. For example, if the caDSR item public id = 2181292, version = 1.1, when importing you would add the RAI, and the result would be an IRID = 2.16.840.1.113883.3.26.2 + 2181292 + 1.1.
