Absolutely. I don't think we have hard, definitive numbers, but there was a recent Red Journal article (
The Holman Research Pathway in Radiation Oncology: 2010 to 2019) looking at the outcomes of those who did Holman (although I am sure there are non-Holman people focused on research).
Nonetheless, in this select group of people from 2010 to 2019, this is what the abstract highlights: Of the 75 HRP graduates currently employed in an academic position, 39 (52.0%) have their own laboratories. Twenty-three of the 96 HRP residents (24.0%) who secured employment in full-time clinical positions after residency switched jobs over the study period.
Back of the envelope calculation, across 10 years, 39 have a laboratory, with nearly a quarter switching jobs during this time, leaving about
3 laboratory positions per year.
I am an MD/PhD, like many of us, who is now primarily clinical in an academic shop. The experience I saw on the job search, data like this, and decreased federal funding, I think I would be hard pressed to find a reason to persuade an MD/PhD student, who wants a physician-scientist career, to look at our field. There seems to me more opportunity elsewhere and ask them to look at those fields before coming back to rad onc.
