MRI-Guided SBRT vs Proton Therapy (5-fraction)

I would speak to a oncologist/radiologist and get second opinions.
I am not sure the research on your comments about photon and proton. Proton beam radiation (which is what I had) is very precise. It has little or no damage from radiation going in, very precise beam. and does NOT proceed past the prostrate or where it is programmed to deliver the radiation.
Photon radiation does proceed past the prostate and outside the body thus can damage additinal tissues and organs that proton does not. I chose proton radiation and got pencil beam based on the physics department at UFPTI and my oncologist/radiologist.
Mayo Jacksonville does the SBRT with photon radiation and even though very precise the radiation does proceed past the prostrate versus proton and thus I chose proton at UFPTI. I think best suggestion would be second opinions and go over the pros and cons of each. Then do some research of your own and decide what is best for you based on the opinions you got and your own research of both treatments.

Thanks JC, that's exactly what I am doing. I have been leaning towards Proton for the reasons you mentioned and I confirmed that my insurance will cover it before I got emotionally invested in it. Either treatment seems like a good option, so I am concerning myself with the QOL side effects and the location of my G7 right up on the capsule, next to the bladder. The MR-guided SBRT has a margin of 2mm (to Proton's 3mm) and it accounts for realtime movement and automatically gating (shuts off) if off target. Also, MR-guided SBRT's urethral-sparing techniques have demonstrated significantly low rates of acute genitourinary toxicity in trials. Additionally, while proton therapy lowers the dose at several rectal DVH points compared to photons, in turn, photons limit the high dose to the bladder slightly better than protons. And the proximity of my G7 to my bladder leaves me with a few questions (which I am pursuing).
