Surgery in rhabdomyosarcoma of the bladder, prostate and vagina.

The treatment of bladder and prostate rhabdomyosarcoma (RMS) is highly controversial. Aside from chemotherapy, treatment modalities include conservative surgery, radical surgery, and pre-, intra-, or postoperative irradiation. Between 1968 and 1993, 78 children with RMS were treated at our institution. In all, 22 tumors were located in the urogenital tract (bladder/prostate, 13; paratesticular, 5; vaginal, 2; others, 2). Altogether, 6 patients had stage II disease; 7, stage III disease; and 2, stage IV disease. All 15 patients with RMS of the bladder, prostate, or vagina received chemotherapy, and 4 had additional radiotherapy. Surgery was also done in 10 patients; parents refused an operation in 3 cases. In all, 3 patients in an advanced tumor stage died of their disease. All other children currently show no evidence of disease (mean follow-up, 6 years; range, from 2 months to 18 years). After chemotherapy, radical operative intervention with multiple biopsies (encircling the tumor)--in contrast to local tumor excision or partial resection--permits complete tumor resection followed by excellent long-term results. Following radiotherapy, often a consequence of organ-sparing therapy, many complications ensued (60%); therefore, irradiation should be restricted to highly selected cases.
