Demographics, stage distribution, and relative roles of surgery and radiotherapy on survival of persons with primary prostate sarcomas.

Disease-specific survival and OS for non-rhabdomyosarcoma histologies appear inferior to those of rhabdomyosarcoma. The addition of RT to surgical resection may improve DSS in locally advanced non-rhabdomyosarcoma. This is the largest report of the incidence, stage distribution, and survival for this extremely rare urologic malignancy providing valuable prognostic information.
