Where can I find clinical data elements specific to my cancer research of interest?
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. EBV status), treatment regimen, slide magnification, histology distinctions, and staging questions.
