NCI Standard CDEs

The NCI regularly reviews and harmonizes CDEs in use by the community. The NCI Standard CDEs represent those that have been through the NCI's Content Owners governance Governance process and have been determined to meet all the necessary criteria for standardization.

CDEs Initiatives

CDEs initiatives are owned by individual NCI Divisions, Offices, and Centers, as well as by NCI stakeholder communities who have chosen to use NCI caDSR as a central repository for their CDEs. The CDEs are organized in the caDSR CDE Browser based on Context and Classification Scheme. 

...

Contexts represent a community who have agreed to share CDEs and CRFs, within a Context end users create Classification Schemes for various projects in their community, and use them to classify and organize CDEs reflection their usage by project. They classifications are not formal Classification Schemes, but are more of a list of keywords and categories familiar to the community of practice. Opening up a Context in the CDE 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.

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

If importing caDSR content from a download into another ISO/IEC 11179 or other similar CDE or CRF metadata registry,

...

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.

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"

Biomedical Research Integrated Domain Group (BRIDG) meta data elements (CDEs)

BRIDG is a model that was created by a collaborative effort engaging stakeholders from the Clinical Data Interchange Standards Consortium (CDISC), the HL7 BRIDG Work Group, the US National Cancer Institute (NCI), and the US Food and Drug Administration (FDA). A logical information model was developed to describe basic, pre-clinical, clinical, and translational research.  Please visit the BRIDG website for more information.

The CDEs in the BRIDG model are available from the CDE Browser in the BRIDG Context under the Classifications heading "Link to BRIDG 3.2", subheading "BRIDG 3.2". They have been downloaded and made available here for convenience.

 BRIDG 3.0.2 is also available in the Attachments section of this page and in the CDE Browser.

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.

Surveillance, Epidemiology and End Results (SEER) meta data elements (CDEs)

The SEER program works to provide information on cancer statistics in an effort to reduce the burden of cancer among the U.S. population.  The data elements collected in cancer surveillance have been registered in the NCI caDSR, and are available from the CDE Browser in the PS&CC Context under the Classifications tab heading "caSEER", subheading "com.imsweb.caseer". They have been downloaded and made available here for convenience.

Health Information National Trends Survey (HINTS2005)
