Jazz,
Here is the next line:
T2c: the tumor is in both lobes
T3: the tumor has spread through the prostatic capsule (if only partially, it is still T2)
Now, I can't say what that qualification means. I am a T3, so it wasn't in scope for me. I had full blown EPE in multiple spots.
The problem with positive margins, as Walsh says in the book, is that you don't know if the cell they found on the margin was the last one cut in half, so dead, or if there were more. The optimist says it is half of the last one.
