title: Radiation to regional nodes for rhabdomyosarcoma of the genitourinary tract in children: is it necessary? A report from the Intergroup Rhabdomyosarcoma Study No. 1 (IRS-1).
abstract: Fifty-eight children with genitourinary rhabdomyosarcoma are reported. Lesions involved the bladder (22), prostate (14), vagina/uterus (6), and paratesticular tissues (16). Fifteen of 58 had positive sampling of regional lymph nodes. Eleven of 15 received radiation to no more than 4500 rad in most cases, and 9 of 11 are diseases free. Two of 15 had no radiation and are disease free also. Twenty-three of 58 had negative nodes. Six of 23 had radiation to these nodal areas and 4 of 6 are disease free. Fifteen of 17 patients had no radiation and are disease free also. Sixteen of 20 patients with no node sampling are disease free; 9 of 16 had radiation but 7 of 16 did not. All patients in the Study had intensive systemic maintenance chemotherapy. One 1 patient failed in regional nodes despite 4500 rad to these node echelons. We suggest chemotherapy and radiotherapy, not to exceed 3500 rad in four weeks, to known residual disease including regions from which positive nodes have been obtained.
