Cancer Research Data Commons Repositories

Repositories in the NCI Cancer Research Data Commons (CRDC) contain related data that have been harmonized and stored in a format that is ready for analysis by the research community. The data are brought together with infrastructure for security, interoperability, and elastic compute capability.

The CRDC is a network of repositories that researchers, tool developers, clinicians, and in the future, patients can use to access and contribute tools and data across scientific domains, such as genomics, proteomics, and imaging, for example.

Each CRDC repository will have a submission and curation process that harmonizes the data and applies standardized metadata to enable sharing and analysis. Repositories will be centered around a scientific domain and analytic and visualization tools will be developed based on the needs and feedback of the scientific community.

Repositories will be populated with data generated by NCI-funded programs. Through the Data Commons Framework, CRDC repositories will interoperate with data from commons being developed by other NIH institutes and organizations.

Current Status of Repositories in the CRDC

There are currently three accessible repositories within the CRDC:

Genomic Data Commons

The Genomic Data Commons (GDC) is a unified repository for genomic, clinical, and biospecimen data from cancer research programs.  The GDC includes data from The Cancer Genome Atlas (TCGA), its pediatric equivalent the Therapeutically Applicable Research to Generate Effective Treatments (TARGET) program, Foundation Medicine (FMI), the Cancer Cell Line Encyclopedia (CCLE), and a growing number of other sources.

Proteomic Data Commons

The Proteomic Data Commons (PDC) offers access to highly curated and standardized biospecimen, clinical, and proteomic data. The PDC includes data from the Clinical Proteomic Tumor Analysis Consortium (CPTAC) program and will grow to include other sources over time. The data are open access and can be browsed interactively using a series of filters and accessed by an API.

Integrated Canine Data Commons

The Integrated Canine Data Commons (ICDC) includes genomics, proteomics, and imaging naturally occurring cancer data in canine cancer patients. Researchers can explore multiple types and collections of open-access data directly through the portal or through one of NCI's Cloud Resources.

Future Development of Repositories in the CRDC

Several repositories are currently planned or under development, including repositories of imaging, immuno-oncology, and epidemiological data.

Data available through the CRDC will come from many sources, including:

The Cancer Data Service

Some NCI-funded programs are generating cancer genomic data types that are not currently accepted by the Genomic Data Commons, so NCI is establishing a Cancer Data Service to broaden the sharing of cancer genomic data.

This repository will accommodate data that:

  • Do not fit the current data type criteria for GDC submission.
  • Do not meet the minimum metadata standards for GDC submission.

Access to Data in CRDC Repositories

Data in the CRDC repositories will be publicly accessible, but some of the data will be controlled and require approval for access, depending on the Data Use Agreements in place.

Each repository will provide information about the data it hosts and instructions on how to gain access.

dbGaP access is required for each researcher who wishes to access controlled data.
