Fairwind is correct but left out one part. There are two staging mechanisms ~ clinical and post operative. the list above is according to the staging manual put out by the American Joint Comission on Cancer or AJCC. When you see a staging on a pathology report you will usually see in parenthesis AJCC2007 or AJCC2002. Every 5 years AJCC will update the tables if necessary. The last major change for prostate cancer was in 2002. The previous AJCC1997 had a stage T3C. You will sometimes see that here. It is still valid it's just that AJCC no longer uses T3C and today T3B is the same thing.
Also worth noting is that post surgery also has a class of stages. They are preceded by a "p". For example I was T1C before surgery and after surgery I was pT3b. The P indicates "Prostate" and indicates that the entire prostate was examined. You will never find a T1 post surgery as those are clinical classifications. This is the primary reason that almost everyone will have a new staging after surgery.
Just a note...
