Effects of Proton Therapy Without SpaceOAR

Posted by danieljohnmyers1 @danieljohnmyers1, May 20, 2022

I have a gleason of 7 (4+3) with an adjusted PSA of 15 (doubled 7.5 due to longtime finasteride use) and an MRI showing extraprostatic extension. Fortunately, a PSMA-PET showed no spread outside the prostate. I've begun lupron ADT therapy and will begin 28 proton radiation therapy sessions in a week. A spaceOAR was not indicated given the extraprostatic extension so I'm wondering of others experiences and impact on rectal functioning throughout therapy and after.

Interested in more discussions like this? Go to the Prostate Cancer Support Group.

Although I had a SpaceOAR with my 43 proton zaps 3 years ago at Mayo PHX, I hear it’s no longer standard protocol, extra prostatic or otherwise. Best wishes…
