Non-extirpative treatment of myosarcomas of the bladder and prostate

Patients who present initially with locally unresectable or metastatic myosarcoma of the bladder or prostate may be treated by a variety of non-extirpative methods. The success of these methods in 4 cases reported here suggests that we should consider this approach more often. While chemotherapy and x-ray therapy are by no means universally effective in myosarcomas of bladder and prostate, we recommend their use definitively and aggressively when surgical extirpation is impossible. In addition, we favor using them preoperatively in more favorable situations. The application of cryotherapy has intriguing possibilities and deserves further exploration.
