Hi Joeven - welcome to our forum. You've landed in a great place to ask questions and get some support, especially with your high risk/metastatic situation. Once the metastases have happened, the "risk" assessment from the Gleason score isn't very important, but it does highlight the aggressiveness of your case.
I've added you to the G9 Crew roster, a thread we've set up so people with this diagnosis can find one another for mutual support. Here's a link. You'll find many there, with links to many of their posts. Please feel free to ask questions, vent, share information, whatever you find helpful.
