Volume 23, Number 2Bladder CancerIntegrating JELMYTO (Mitomycin) for Pyelocalyceal Solution Into Community Practice: Practical Tips for the UrologistMichael J. ShannonSandip M. PrasadTreatment options for upper-tract urothelial carcinoma are based on whether the patient has high-risk or low-risk disease. Low-grade tumors can be managed with nephron-sparing approaches, including ureteroscopic resection and ablation, although most patients undergoing endoscopic treatment of upper-tract urothelial cancers face a risk of recurrence. Mitomycin gel for pyelocalyceal solution provides an effective alternative therapy. In OLYMPUS, a phase 3, single-arm, open-label study, 58% of patients with low-grade disease experienced a complete response to induction therapy at 3 months. Kaplan-Meier analysis revealed an estimated 12-month durable response rate of 82%. The most common treatment-emergent adverse events were ureteric stenosis, urinary tract infection, hematuria, and flank pain (grade <3). Mitomycin gel offers a novel, kidney-sparing, nonoperative approach to managing low-grade upper-tract urothelial carcinoma.MitomycinUrologyDrug therapyUrinary tractCarcinomaUrologic neoplasmsurinary bladder neoplasms
