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, where a Guest account and password are provided for your convenience.

TCGA Phase II meta data elements (CDEs)

Project CDEs

CDEs are organized in the caDSR CDE Browser based on Context and Classification Scheme.  Opening up the Context name in the browser will reveal a "Classifications" node, that when opened will list all the projects in alphabetical order. Clicking on a project node will search for all CDEs used by the project.

TCGA Phase II meta data elements (CDEs)

TCGA (The Cancer Genome Atlas) is a project funded by the National Cancer Institute (NCI) and National Human Genome Research Institute (NHGRI). A project overview can be found on the TCGA Home Page.

 

...

TCGA provides data element descriptions for the clinical data elements found in the TCGA data files.  The BCR on-line data dictionary displaying the essentials of the clinical CDEs as an HTML page is located here.  The files below contain all the caDSR metadata for these CDEs.  The HTML data dictionary was generated from the XML download of the TCGA CDEs. For more information or help creating your own HTML Data Dictionary from NCI registered CDEs, please contact the NCI Help Desk.

They are also available from the CDE Browser in the caBIG Context under the Classifications tab heading "TCGA 2.6 by Disease".  New TCGA CDEs not yet in the BCR data dictionary can be found under the caBIG Classification "The Cancer Genome Atlas", sub-heading "New TCGA Data Elements"

North American Central Cancer Registries (NAACCR) meta data elements (CDEs)

 

...

NAACCR develops and promotes uniform data standards for cancer registration, and aggregates and publishes data from central cancer registries. It promotes the use of cancer surveillance data and systems for cancer control and epidemiological research. See their website for more information about NAACCR.

NCI has registered several versions of the NAACCR data elements as CDE metadata in caDSR for discovery and use by those wishing to utilize the NAACCR data, or create data repositories of compatible data.

The following

...

versions of NAACCR have been recorded in caDSR, are available from the CDE Browser in the PS&CC Context under the Classifications tab heading "Division of Cancer Control and Population Sciences". They have been downloaded and made available here for convenience.
