A recent experimental study took a limited number of patients (120 total patients) with a history of superficial/early stage bladder cancer and split them into 2 groups. The first group underwent standard treatment with "bladder scraping" (TURBT), followed by Mitomycion C chemotherapy in the bladder once a week for 6 weeks. The experimental group instead underwent Mitomycin C in the bladder 3 times a week for 2 weeks. When the bladder was then inspected, 57% of the experimental group had complete tumor response and many were able to avoid surgery. These are very preliminary results, but may be a new line of treatment for recurrence of superficial bladder cancer in the future.
