Management of metastatic malignant melanoma of the bladder.
Recombinant interleukin-2 (IL-2) has demonstrated antitumor activity and durable clinical responses in patients with metastatic melanoma. Careful screening and selection of appropriate patients has improved the safety profile of IL-2 administration. Gross hematuria would ordinarily preclude the safe delivery of IL-2. We report a case of metastatic melanoma to the bladder presenting with hematuria. A complete resection was performed and subsequently allowed the administration of high-dose, bolus IL-2. The combination of resection and IL-2 therapy resulted in a partial response maintained for more than 18 months. Symptomatic bladder melanoma should be aggressively treated to allow for systemic immunotherapy, which can provide durable responses.
