Hi Rosemary,
I've known a number of folks receiving Mitomycin after TUR's but it's still not standard as far as I can tell. There are reasons to think that perhaps it should be...
Your other question, cytology tests can detect abnormal cells including cancer cells. If negative, no malignant cells were found; if positive, then that's not so good. However, cytololgy tests are not 100% infallible, unfortunately, especially is the cancer is of low or intermediate grade. Luckily it's more reliable when detecting high grade tumors and/or CIS.
I've also read that results may differ from lab to lab, which means there is some room for improvement. It's still a standard test though, the newer urine marker tests like FISH and NMP22 have only recently been approved and need a lot more study. I'd say using one of those in addition to cytolology is probably worth the time and extra cost (not all that much considering).
Your last post in this thread is about blood markers, this has been studied for many other cancers, those markers you cite are used in breast, ovarian, colo-rectal cancer and more. But till now none of the tumor markers have been used for bladder cancer, this study is breaking new ground for us and I'm glad to see it. A blood test is much less invasive than so many othet tests out there.
Take care, and all the best with your BCG treatments.
