Hi Stephen,
When I was diagnosed back in 2007, the consensus seemed to be that Prostectomy was not an option for guys with Gleason 9, because no matter how sharp the scalpel, some microscopic cancer cells would inevitably break away during surgery and spread about the body via blood and lymph systems, going on to cause metstastacies (never could spell that word) all around the body.
The thinking was that with lower grade Gleason scores this didn't matter because the individual cells were not very cancerous, they were not as aggressive as Gleason 9's and 10's so didn't have the potential to cause so much trouble.
The idea was for Gleason 9's that you would have 6 months of HT to shrink the tumour and then give the whole thing a good blast of external beam RT, and keep the HT going for another couple of years, to give the tumour plenty of 'teddy' so to speak.
Now obviously science has moved on and I was recently offerred a prostectomy as a salvage treatment, however to my way of thinking there is something in the old science, the logic being that if you have Gleason 9 and it is contained within the capsule, it is really a good idea to keep it within the capsule?
I guess there may be some Gleason 9 guys on this site who have had surgery and can give you a more modern view of the pro'sand con's.
