Welcome to Healingwell, and the "reluctant brotherhood"
Sounds like it's on the move but still with a good chance for a cure. What have you done so far? First thing you should consider, in my laymans opinion, is send the slides to Johns Hopkins, or Bostwick Labs, for a second opinion on the Gleason, if you haven't already.
It's a very subjective thing to read, and you want a second set of eyes that sends lots of time looking at prostate cells.
There are lots of G9 guys here and very knowledgeable guys, that will chime in soon, so stay tuned.
