Here is a page on the Sloan-Kettering web site that may be of assistance.
Click on "Prostate cancer prediction tool".
I clicked "no" on case saving function.
What comes up is a pre-treatment nomogram. But you can click on "Change Treatment Stage" -- "Post Radical Prostectomy" to get the chance of recurrence at that phase.
Perfect! Thanks for this!
bluebird and myman, thanks for your responses also. As a mathematician, I am quite aware of statistics and what they are and are not, and of course try to have as positive an outlook as possible. I am also aware that nothing in this life is guaranteed. Having said that, I feel the statistics are another piece of information that I wanted to have. Knowledge is power, after all. Thanks for the help and positive thoughts!
