Great summary. Although I chose 5 treatment proton at Mayo Rochester where they use Hitachi kit, the statement, "There are no well designed randomized studies comparing proton with photon" is consistent with all I have read and been told by urologists and radiologists. The one statement made by those perfming the procedure that I question is whether Radical Prostectomy is still the "Gold Standard". Photon and Proton have been shown to have equal long term outcomes.
