In my hospital chart from 2021, I recently noticed that my then-radiation oncologist referenced STAMPEDE as justification for doing radiation on my prostate despite the fact that my cancer was/is stage 4 oligometastatic.

Apparently that was still a new-ish idea in 2021, so he felt a need to explain himself. Also, the team's head oncologist was on leave and he was a resident, so a clear decision trail was probably doubly important. (He supervises his own team now, and well-deserved IMO).
