The NCI caDSR CDE Browser can be used to download collections of meta data metadata describing data held in repositories for cancer research and clinical trials.

The caDSR Form Builder can be used to create, view and download the Case Report Forms (CRFs) designs.

Currently, CDEs can be downloaded in Excel or XML Format, CRFs can be downloaded in Excel format.

It is not easy for occasional or novice user users of the CDE Browser and Form Builder to discover collections of CDEs or CRFs, since the high level organization of CDEs and Forms in the Navigation Tree is by Context, not topic. After selecting a Context, one can browse the Classifications, but this may not be intuitive, and some find the use of the Advanced Search, which also offers search by Classifications, dauntingModernization of the caDSR content access services is planned.

In addition to the usability issues noted above, attempting to download all the caDSR CDEs would result in a file size that is too large for a single MS Excel download, and currently forms can only be downloaded one form at a time.

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