The big programs including MSKCC, MDACC, MGH/Harvard, Duke, Hopkins, train Heme/Oncs either over 1 or 2 additional years. As you have already completed a fellowship, there are things about you that make you more competitive. If the program includes a lot of neuro-based call as a fellow, this could be tough as status epilepticus in a cancer patient may be beyond your skills. Not all the programs include fellow call, and most have neurology residents as first call. You are way ahead of the neuro trained folks from the oncology perspective. We have to learn as much oncology as we can, typically over a 2 year fellowship. I know 3 folks who have gone your route, all with good jobs after fellowship in university or private settings. It adds to the field, to have people trained from both paths IMO. The UCNS board certification in Neuro-Oncology is a neurology based test, for neurologists who train in Oncology. However, if you are IM/Heme/Onc board certified, the UCNS certification won't mean a damn thing. Those of us that have the certification still aren't sure what it means exactly. Go for it dude.
