Hi Polaris1!
Welcome to the forum, sorry you need to be here. I've added you to the roster of the G9 Crew, a thread we have for people with that diagnosis. It is pretty shocking and worrisome to get that news; on the thread, you'll find many guys, most doing quite well even with a G9. It's a gathering place for us to discuss some of our specific concerns, and to peruse other people's situations and their decisions.
Here's the link to the thread:
The Gleason 9 Crew -- Part 2, continued.As a 5+4, you are in an even more exclusive group. We only see around five or so new 5+4 cases a year here on the forum. Those type 5 cells are aggressive, and having them dominant is a higher risk yet. There are darn few of us 5+4 types, so it's hard to find study data for us. They lump us in with other risk groups so they can have a big enough sample size to draw conclusions.
Surgery vs. radiation is a tough call. If it is truly well contained, surgery can be effective. There are some studies just in the last year or two that are pretty encouraging about
the success of surgery even with the high Gleason cases.
Mine had too many indications that it was locally advanced already for me to choose surgery. Radiation is pretty easy to tolerate. Mine was external beam only, with HT. Adding the brachytherapy boost (or brachytherapy with EBRT boost if you want to think of it that way), for the so-called "triple play" has been shown to be very effective, though with some increase to risks for urinary tract complications (strictures). There are guys here who've done it either way.
You may be finding it hard just to keep breathing right now. It's a real gut punch. Stay with us, it will get better as you begin to develop a plan.
