I was diagnosed with pTaG3 (i.e. aggressive cancer, but only in the first layer) with evidence of CIS (aggressive pre-cancer cells that lie flat on the surface) in January 2014. I had two TURBTs to start with, and then BCG treatments since. All bar one of the biopsies taken following each set of BCG treatments have been clear, with a very small amount of CIS in one. Unfortunately the disease and treatments have combined to significantly reduce the size of my bladder, and I may not be able to continue with the last year of BCG. I will have regular monitoring through urine cytology tests and cystoscopies, and hope the cancer and CIS don't recur.
I found the following publications online, which you may find useful:
UK Guidance for the treatment of bladder cancer:
European Association of Urology guidance for the treatment of non-muscle invasive and muscle invasive bladder cancer:
Guys & St Thomas Hospital leaflet regarding maintenance BCG:
There are two UK websites for further information and support:
