I have not had the gel but have had two instillations of liquid mitomycin for low-grade NMIBC. The chemo caused severe irritation and bleeding in my bladder lining for 1-2 months. That was almost 10 years ago. After another recurrence this year, I consulted with the urologist who treated me then. She no longer treats bladder cancer but remarked that I was her only patient to ever react to intravesical mitomycin in that way. The curious thing is she said we would use something different next time, as if she expected it to recur. After 9 years with no disease, I thought it was over. But it keep could keep coming back, no matter what drug is instilled. So, where do we go from here? I'd like to know, as well, although I suspect that whether it's liquid or gel, mitomycin is still mitomycin. Your recurrence notwithstanding, did you have gentle side effects with gemcitibine? At any rate, I wish you the best possible outcomes with all your treatments. And as I pray for myself, that we stay on top of it, and it doesn't progress. It's a journey, right? Take care of yourself. -Jacqueline, Moderator (Bladdercancer.net)
