[Genitourinary rhabdomyosarcoma in childhood].

We present the result obtained by GICOP in the treatment of 12 genitourinary rhabdomyosarcoma, located in vagina-uterus (5), bladder-prostate (4) and paratesticular (3). The age of the patients ranging from 1 to 15 years. Embryonal rhabdomyosarcoma was the most common histologic type (58 for 100) being the major number of cases in stadium II. The treatment was based in the combination of chemotherapy protocolised with vincristine, d-actinomycin, cyclophosphamide (VAC), vincristine, adriamycin (VAC-VAD) and/or iphosphamide, vincristine, d-actinomycin (IVA), use of radiotherapy, marrow auto-transplantation and radical surgery avoidance. Complete remission was achieved in 11 out of 12 cases (92 for 100), relapsing in 5 cases (38 for 100) of which 4 (80 for 100) achieved a second remission. An 82 for 100 disease free survival was achieved in a 5 year period.
