Hey. Short-tracker/single boarded med onc here. Very smart of you to think ahead so as to not close doors. As a happily failed MD-PhD in community practice, I’d advise everyone to think about that.
As for short tracking, no one will care about that whatsoever.
Single boarding may be relevant. The vast majority of places I talked to didn’t care, even if they were general heme onc jobs, but there were a few places that explicitly wanted double boarding.
I would keep in mind two things:
1) If you’re double boarding, short tracking isn’t actually shorter. If you short track IM, fellowship becomes 4.5 years total. If you’re single boarding, it’s 4 year fellowship which is the same length as IM/hem-onc without short tracking. The true short track is 3 year IM and 2 year med onc fellowship, but that depends if your program allows it.
2) Much more important than whether you double board or not is the type of program you go to. If you end up at a big academic place with all sub speciality faculty, that’s great in some ways but it also means it will be harder to become familiar with all heme-onc. And fundamentally, the main limiting factor on your ability to get jobs is what tumor types and what benign heme conditions you’re comfortable treating. My best advice is get the broadest training you can and specialize after if you want, not the other way around.
