Hi Jimmy,
You really need to get your PSMA scan results, because that will decide if there are curative options available. These might include focal therapies to the prostate, and maybe cyberknife if you have a only a small number of mets in certain other places. Prostatectomy might be an option too, although rarely performed after radiotherapy.
You may need to be pushy here. Many hospitals don't think to suggest treatments they can't offer themselves (one of my pet peeves), and for salvage treatments, you may benefit from treatments only available at the main cancer centres of excellence, which may mean referral for second opinion.
If there aren't curative treatments available, then you are on to long term management of the prostate cancer with hormone therapy.
