A Management Algorithm for Mitomycin C Induced Cystitis

Bladder Cancer
Amy N LuckenbaughJeffrey S Montgomery

Abstract

Background/Objective: A post-bladder tumor resection dose of MMC can reduce non-invasive papillary (pTa) bladder cancer recurrences by up to 40%; this treatment is recommended in both the AUA and EUA non-muscle-invasive bladder cancer guidelines. A common complication of this treatment is eosinophilic cystitis. Symptoms range from mild urinary frequency and urgency to debilitating pain and dysuria. Currently, there is no established treatment algorithm for MMC-induced cystitis. Methods: Members of the Urologic Surgery Quality Collaborative (USQC), a group composed of over 160 private and academic urologists, met to discuss the management of patients with cystitis following MMC therapy. They devised a treatment algorithm based on experiences of urologic oncologists and neurourologists to aid in the diagnosis and management of MMC-induced cystitis. Results: The assessment begins with urinalysis and culture, followed by cystoscopy. For mild symptoms, behavioral therapy, including timed voids, fluid restriction and Kegel exercises are trialed. If symptoms have not resolved, treatment with an antihistamine, followed by a combination of anticholinergic and alpha-blocker medications. For persistent symptoms or severe symptoms at prese...Continue Reading
