Yeah, when RT is giving as the primary treatment for PC, not uncommon to go 39-42 treatments, usually from above 70 gys to sometimes over 80 gys. That is because there is a prostate in place, of course.
With our SRT, Salvage Radiation, it can range from 33-39 typically for treatments (not in all cases), and the gys can be as low as 60 to the mid 70's, depending on the individual data and history of the patient.
I went for 39 great ments for a total of 72 gy, which is higher than average in my area for SRT.
I saw the same radiation oncologist each and every week of my treatments, same one that made my plan. Usually saw her every Monday.
The urgency you describe is very typical side effect while going through the SRT, never experienced that, since all mine were done with a catheter in place. Since you have to travel so far, might be wise to take the tablets from the dr, should ease some of those feelings.
As far as those stronger doses given over lesser time, my own dr. said that not member people could endure that much radiaition poisoning without really getting sick or having more serious side effects. From my own experience, I would tend to agree.
Good luck as you continue. You are getting there, a day at the time.
