Paul, I had never heard of this but after all the posts from you and others, this treatment sounds really good for certain cases: a whopping dose of radiation precisely placed at the tumor without the negative effects of damaging the surrounding tissue, as it is not a beam or a wave or a pulse.
That killing dose followed by EBRT to ‘mop up’ the surrounding area along with ADT sounds about as comprehensive a treatment as you can get - even more-so than surgery IMO.
Best of luck with your treatment and please keep us posted on your progress!
