I find that I always learn new things when I re-visit things I have already read. I was perusing the section on CIS under the BLC information of this web site, and was struck by the following excerpts..

Occasionally (1% of cases or less), CIS is found without associated invasive TCC (primary CIS"
QUESTION: what does the part about "usually associated with concomitant high grade invasive TCC..." mean? I was under the impression that CIS was "controllable" with BCG, or, at worst, bladder removal. Is it USUAL that it has already spread? Guess I am in a bit of a panic, confused.
