Like Tudpock, I feel that you and your husband have been tossed around with respect to possible treatments. Or, perhaps there are misunderstandings that need to be cleared up.
Nothing wrong though that I can discern with conventional proton therapy. Let me mention though that there are numerous reports that show that this more expensive treatment has no advantages over conventional (IMRT) photon therapies.
You have also been given erroneous information with regard to (photon) SBRT. There are numerous papers that show that this method has good outcomes for patients such as your husband. If necessary, it can be augmented with IMRT and ADT (hormone treatment).
I believe that the pencil beam proton SBRT (five sessions) is off the table for your husband. This is GOOD, because that therapy is still experimental. During a very recent visit, I specifically asked my radiation oncologist (with well over 100 refereed papers in the field) about
this and he told me that the alignment method used in photon SBRT is more precise than with a proton machine. This is important for accurate dosing because the prostate moves while the patient is 'on the table'.
Good luck on choosing the best methodology.
