RE: Mitomycin, I was diagnosed with CIS. Have been clean for 18 months with the usual cysto/BCG routine. I am now being treated at MDAnderson due to relocation to TX. After a clear cysto last September, I should have had the usual 3 treatment course of BCG, however, it was not available to me at that time. MDA decided to put me on Mitomycin once a month for 6 months as an alternative protocol, and then have another cysto. Fortunately that was all good, except some spot of inflamation. They did follow-up biopsies to make sure nothing was lurking. All negative! Now I'm on 1/3 dose of BCG for 3 treatments. I'm having a lot of side effects this time, whereas I did not previously. They are saying that I'm getting a strong response from my immune system.
By the way, MDA no longer uses the Clorox protocol after BCG! They say you can use any toilet as long as it is high flo - not your home toilet for most people. I have been treated at 3 different facilities and each seem to have their own procedures.
