Access Data

The GDC supports the submission of clinical and biospecimen supplements. Supplemental files can be downloaded from the GDC by searching for the Data Type "Clinical Supplement" or "Biospecimen Supplement" from the facet search in the GDC Data Portal Repository. For TCGA data, the supplement data is provided in XML documents and tab delimited files (biotabs). These files, in varying degrees, provide information on marker status (e.g.

TCGA “collection” represents the collection of the sample for TCGA, whereas “procurement” represents the removal of tissue from the patient.

The GDC harmonizes data across projects. This includes aligning the genomic data to a common reference genome (HG38) and generating higher level data using GDC bioinformatics pipelines. Other repositories may process the data differently.

The TCGA marker and other landmark cancer genomics papers, as well as associated supplemental files, are available on the GDC Publication Pages. The Publication Pages provide access to publication information and supplementary files.

Submitting treatment data is optional as not all projects are associated with treatment studies. For TCGA projects, for example, not all projects and cases have treatment data. For TCGA projects with treatment data, information is available in applicable clinical supplement files (i.e. clinical XML, biotabs). For other project associated with treatment studies in which the treatment data has been submitted to the GDC, treatment data is available for download in JSON and TSV format. These studies may also contain clinical supplement files.

The availability of follow-up data is specific to the project and associated study.

For the Multiple Myeloma Research Foundation (MMRF) Clinical Outcomes in Multiple Myeloma to Personal Assessment of Genetic Profile (CoMMpass) study, longitudinal information was generated to track patients over the course of their disease. This data is available in the GDC by viewing the clinical follow-up data available for download on each case page in the GDC Data Portal or by querying the GDC API.

The GDC’s Data Release 26 features updates allowing Multiple Myeloma Research Foundation (MMRF) CoMMpass data to be explored directly in the GDC Data Portal.

The GDC’s latest data release includes two major National Cancer Institute projects: the HIV+ Tumor Molecular Characterization Project (HTMCP) and Cancer Proteomic Tumor Analysis Consortium (CPTAC)

The GDC has released data for over 44,000 cases from the American Association for Cancer Research’s Project Genomics Evidence Neoplasia Information Exchange (AACR Project GENIE, phs001337), includi

Data from the Multiple Myeloma Research Foundation (MMRF) is now available at the GDC.
