Bladder leiomyosarcoma: a review of 10 cases with 5-year followup.

Of 10 patients with leiomyosarcoma of the bladder followed for a minimum of 5 years 4 remain free of disease at 5, 6, 6 and 9 years, respectively, following partial cystectomy. An additional patient who was treated sequentially by radiation, radical cystectomy and chemoimmunotherapy survived for 10 years before death of metastatic disease. Wide surgical extirpation (partial or radical cystectomy) remains the curative treatment of choice.
