My primary treatment was IGRT/IMRT. I had possible lymph node involvement as well. So, the treatment consisted of 45 total doses. The first 25 were a combination treatment. I received what is called "full pelvic" radiation. I believe this is what they will do for seminal vesicle involvement as well. So, for the first 25 the machine would buzz a bit and then I could here the collimeters leaves reposition and it would buzz a bit more. The first buzz was the full pelvic. The second buzz was focused on the prostate. The machine would then move to the next station and repeat the process. There were seven stations in the treatment arc. The radiation machine was a Varian. The last 20 were only aimed at the prostate and this cut the time for treatment in half. Although none of the treatment sessions took more than 20 minutes in to out.
I had minor bowel and urination issues the last five treatments of the full pelvic and things got better fast when we went to the prostate only. I have had no lingering effects from the treatment other than ED. Somehow, though, I think the ADT therapy is more to blame for that than the radiation. Of the two the ADT was the more unpleasant, but tolerable, treatment.
Good luck to you Dad. I hope his treatment is a benign as mine was.
