I'm kind of in the same situation. I haven't yet made my decision, though I must do it soon. I already had the gold seed implanted and today I'll do the simulation and next week I'm supposed to start IMRT.
However, I had never heard of SBRT, so yesterday I began furiously to research the subject and even contacted UCLA to ask about
doing it there.
The problem I have is that some specialists I contacted warned me that there's no long term comparison studies to know what the side effects could be. That's because SBRT is still a new thing and therefore there's no reliable data on side effects.
Certainly a 5 day course of Rx sounds so good vs 49 days of it,doesn' it?
Thank you for hearing me out...
