From literature I know that a few TCGA samples have also information about treatment. It isn't clear to me how to obtain that information. After downloading the clinical data sets with TCGAbiolinks package I see one column "treatment_id". Each TCGA sample has a code in this column, looking like this: dbf26982-97b4-59f7-b165-d3889623bc21.
I can't figure out what that means, or how I can translate the code into drug name. Any ideas? Or is there an other way, how to obtain the treatment information outside the "clinical data information"?
