I'm using the TCGA/GDC data related to Colon Adenocarcinoma (COAD) I have retrieved the data from Firebrowse: that allows a simply access to the data.

I downloaded the clinical data: gdac.broadinstitute.org_COAD.Merge_Clinical.Level_1.2016012800.0.0/

and I'm using the file COAD.merged_only_clinical_clin_format.txt

that contains the clinical feature of each patient.

My problem is that I can't find anywhere the description of those clinical features. Ad examples there are:

  • patient.follow_ups.follow_up.new_tumor_events.new_tumor_event.days_to_new_tumor_event_after_initial_treatment
  • patient.new_tumor_events.new_tumor_event.days_to_new_tumor_event_after_initial_treatment

From the name is not easy to understand exactly which is the difference of this features. And the same happens for other features.

I gave a look to but the amount of information is very limited.

Where can I find additional information about these clinical information?

The information you wanted was stored in but it was recently removed. For the GDC data model the description can be found here: However, those fields are not listed.

Maybe sending and email to TCGA or GDC support might help you.
