Hi, I am using the clinical data from TCGA. But there are some clinical informations that I don't understand.Such as "days_to_drug_therapy_start","days_to_drug_therapy_end",
"days_to_surgical_resection","days_to_radiation_therapy_end","days_to_new_tumor_event_additional_surgery_procedure".the values of "days_to_surgical_resection" is -6213. I really need some help.Another question is why some patients have two different "days_to_surgical_resection"? this means these patients had two surgical resection?

To update the old answers, the data dictionary has once again been moved.

As for the "days_to_drug_therapy_start" and "days_to_drug_therapy_end" columns of the drug annotation file, the little information I could find suggests these to be days from the date of initial pathological diagnosis. (lists days_to_treatment_start as "Number of days between the date used for index and the date the treatment started"; does not specify what the index date is) (defines "days to treatment" as "The number of days from the date of the initial pathologic diagnosis that treatment began.").

Hope this helps others having to work with TCGA drug and radiotherapy annotation files.
