You could look at the " Predict Prostate" site. It was done by Cambridge University and compares survival at different stages and the difference between radical treatment and surveillance.
I found it enlightening in that there was such a small difference whichever way you go. ( Especially in the lower grade cancers) and it has made me question whether we did the right thing. Unfortunately it doesn't give you recurrence rates which is what most of us probably fear with the prospect of more unpleasant treatment.
I am not very good at adding a link but if you just Google Predict prostate it will come up easily enough.
As for the American nomograms we in the UK seem to have worse outcomes for some reason and it can vary depending on hospitals and who treated you.
It must always be remembered that these are only averages and we are not just a statistic.
