You may even consider asking how many open prostatectomies he has done and consider that route. open and robotic are really equal in results.
I am also a Gleason 9, and I elected to have surgery. But the odds are good that you will need radiation also. If I were to do it over, and found the right doctors, I may have chosen seeds and IMRT, or just IMRT.
It is a confusing time of dealing with reality, learning so much about prostate cancer, and the treatment options. The tendency is to rush, when in all likelihood, 6 months wouldn't make a lot of difference in the outcome.
I would advise multiple opinions from multiple disciplines. Seek out experienced doctors. It is generally felt that a doctor needs several hundred surgeries to be considered to have mastered robotic. That is not to say your doctor won't do a fine job, but with a Gleason 9, you need every advantage you can get.
Good luck on your journey. I am 2 years post op and feeling great.
