@dgd1953 hey, thanks for your input.

I am 3+4 with high decipher. thinking of IMRT at UNIV. Chicago. (similiar to VMAT) in 22sessions with 68 gy. photon.

question. why did you choose VMAT? where did you get it done? did you think about Proton therapy also?

thanks. good luck with next PSA test.

@matthewdore I went to a local hospital which is an affiliate of one of the big Boston hospitals. It was a 20 minute drive, so relatively convenient.

It was the RO who thought VMAT (a form of IMRT) would be best and that I did not need ADT (contrary to what my urologist and Decipher recommended). Looking at proton, I learned that the outcomes and QOL issues were very similar between photon and proton, so I decided to stay local. I’ve interacted with three different ROs at this hospital all of whom have been trained and taught at Ivy league schools (UPenn, Harvard, & Brown), so I felt that I was in good hands.

It’s now approaching three years since my treatment and things are going well. I did have two brief “blood in the water” sessions in the last two years, but they both cleared up quickly without any sort of intervention. I did have a colonoscopy last year that showed evidence of radiation proctitis, but no bleeding was observed. The ED I had before treatment got worse after undergoing radiation, but the combination of Trimix and a VED allows me to still be sexually active.

My latest PSA number came in at 0.18 which is the lowest it has been since this adventure started. I believe that I received excellent treatment and am pleased with the outcome.

@matthewdore
VMAT Uses a 3-D treatment that circles around your body to treat the prostate without Going into other areas. IMRT doesn’t do that.

This requires much more complex programming to do the treatment.
