My mentor Tall Allen gave you the cliff Notes, SBRT but allow me to expound.
All of the other radiaiton oprions by the time you also do brachy plus the "boost" have the same drawbacks as what you noted in #2, EBRT, 7-9 weeks elapsed time.
That was a big negative for me too. So I chose SBRT which can be done in 5 fractions every other day in a week and a half @ 8 Gy each for a total of 40 Gy versus the other radiaitons typcially are 79 Gy - 81 Gy in total and just take longer to do that in smaller more numerous doses.
So that gave me over a month of my life back as opposed to daily back and forth with fatigue setting in abut week 5. I had no adverse side effect so far but only been since Oct 20th last SBRT fraction.
The one drawback is that so far there are only about
7 years of history that bench marks favorably with IMRT/EBRT etc. My rationale was that this was true in the day for IMRT and even for RALP. no long term history until enough people had undergone the procedure and enough time had passed.
I am G9 so chose to concurrently do Provenge to leverage the abscopal effect
prostate-cancer.org/abscopal-effect/To qualify for Provenge you would need two PSA increases at least 14 days apart.
For G9's SBRT is only available in LA, NY or Toronto. I would suspect for G7's SBRT or its cousin Cyberknife is available in a lot more places.
You can find out more on
Cyberknife.com Casper, since you are in UK, I am not familiar with what your options of treatments and locales may be.
