BCG is considered the standard treatment, but 8¼ years ago when I was treated for high grade superficial bladder cancer plus CIS, my urologist also preferred Mitomycin C. He said he had better results with it. I can't tell you if it's luck, Mitomycin C, or his surgical skills, but I've never had a recurrence.
