Try to gather your self away from total fear to decisions for your best course of actions and possible outcomes. Results in high risk patients can vary and cure may possibly never be in the cards, but winning many battles within the war is most important and even encouraging. How the heck would I know???? I had similar pathology to yours and the 12/12 biopsies all loaded with PCa and Gleasons 7,8,9's found, psa was 46.6 (lower than yours). The good news is that was over 11 years ago now and with alot of considered and used protocols for control of the blanking dragon. Now the battles are getting more omnious, but I was aware of that along time ago. I am not done with possible choices still that exist and so it continues as a warrior against the blanking dragon.
Checkout www.yananow.org and patient histories/mentors/experiences (900+ patients), see some histories and stories similar to ours for some idea of what this journey is like. Truman Seamans story is there his psa was like 2500+ or more and nasty stats from diagnosis day.....short story is he lived around 10-12 years or so with an omnious start. He had some good oncologists on his case which might have helped alot. You can run your numbers in a nomogram to get an idea of statistical concepts of cure, might not be encouraging to know and it is not in stone as to your outcome anyway, it is an averages thing. Knowledge is useful and you have the possiblity of many choices in protocols, especially with the right kind of PCa advocate type of doc. You might want to post your story there too after a little while (when ready), alot of us have done so and you can update it often over time. Learn all you can about the protocols and drugs used, because you will likely be choosing and using these in your arsenal.
Once you get control of this and doing alright, time passes by alot easier, even though we all sweat out the psa and other marker tests. I got monthly psa tests for about 2 years, watching this beast and it was useful as to when to switch drug protocols before psa went rogue. Had really good control until about one year ago and now the bigger battle is on. I am not complaining from where I started, included ER room for total urinary blockage from PCa, then diagnosis. Hope is eternal and more protocols keep coming, finally now. So, get your mindset on how to fight this sob the best you can and be envolved in your own choices, as only you walk the walk.
