SBRT: Every day or every other day; proton or photon

Posted by bhDC @bhdc, 3 days ago

Thanks to everyone for their participation in this forum. Your comments and questions have been enormously helpful to me. I'm considering SBRT and trying to determine the answer to two questions: (1) if you have the choice, should you push to do radiation every other day (or simply not continuous days in a row) just to give your body a rest; and (2) if you have the choice (all things being equal) between SBRT with photon or proton machines, which is better? Thank you for any and all reactions

Has to come from within yourself of what is best for you not what was best for me or others.

Both high dose and low dose radiation have their pros and cons. Same goes for proton radiation and photon radiation. They have almost identical success rates. What is different in may cases is side affects or different types of treatments and dealing with long term treatments low dose and high dose short treatment times.

For me I chose 30 rounds of proton radiation. Why? I had two different opinions visits. Then met with my PCP at Mayo and we decided as a team what was best for me not only physically but mentally.

@bjroc
I have asked my DR. at Mayo which machine they are going to use on me. They haven't answered my question yet. I'm guessing it w/b the Varian Probeam or the Hitachi.
The biggest question for me is would I want the advantage of the MRIdian with 2mm margins or the Proton CT guided with the stoppage of rays at the prostate target? Mayo doesn't have Mridian I'm told. Studies show markedly better results in complications with bladder, urethra issues with MRIdian.

I meant the Varian Ethos not ProBeam
