  • Title: Rhabdomyosarcoma of the prostate in childhood: current challenges.
    Author: McLorie GA, Abara OE, Churchill BM, Greenberg M, Mancer K.
    Journal: J Pediatr Surg; 1989 Oct; 24(10):977-81. PubMed ID: 2809970.
    Abstract:
    Since 1978, six boys with prostatic rhabdomyosarcoma have been treated at our institution. Three had localized disease and were managed by initial biopsy, vincristine, actinomycin-D, and cyclophosphamide (VAC) chemotherapy, and bladder-sparing surgery with or without irradiation. Further combination chemotherapy ("pulse" VAC, Adriamycin, VP-16, cisplatin, and ifosfamide) was continued for 20 to 22 months following the induction course. Two boys had microscopic residual disease undetected by frozen section and unresponsive to radiotherapy. Subsequent total cystectomy 4 and 7 months later resulted in eradication of disease. In one patient, preservation of the bladder was achieved at the age of 3 months for 8 years. Artificial sphincter inserted to cure his urinary incontinence failed because of ischemia secondary to cuff compression and scar tissue. He is alive today with a modified Koch pouch urinary diversion. Of the 50% who had metastatic disease at presentation, two were dead within 12 months despite aggressive chemotherapy and irradiation. The third is currently on treatment. Although chemotherapy has markedly improved the prognosis, surgery is still necessary in most cases for cure. Bladder salvage is a desirable goal; however, residual microscopic disease, difficulty with frozen-section disease detection, and poor tissue vascularization for subsequent sphincter replacement remain significant obstacles.
