BACKGROUND Intergroup Rhabdomyosarcoma Study (IRS)-II, (1978-1984) had the general goals of improving the survival and treatment of children with rhabdomyosarcoma (RMS). METHODS Nine hundred ninety-nine previously untreated eligible patients entered the study after surgery and were randomized or assigned to therapy by IRS Clinical Group (I-IV), tumor(More)
The results of treatment of 686, previously untreated patients younger than 21 years with rhabdomyosarcoma or undifferentiated sarcoma, who were entered on Intergroup Rhabdomyosarcoma Study-I (IRS-I) were analyzed after a minimum potential follow-up time of 7 years. Patients in Clinical Group I (localized disease, completely resected) were randomized to(More)
Histopathologic material from 1,782 patients registered in the Intergroup Rhabdomyosarcoma Study Committee (IRS)-I and -II were reviewed by the IRS Pathology Committee in order to provide a uniform approach to classification and correlate patient survival with tumor type. Categories considered eligible were the four types of rhabdomyosarcoma (RMS) (criteria(More)
Prestudy patient characteristics and specific therapy of all eligible patients with rhabdomyosarcoma entered into Intergroup Rhabdomyosarcoma (RMS) Studies I (IRS-I) (1972 to 1978, n = 686) or II (IRS-II) (1978 to 1984, n = 1,002) were examined for their relationship to survival within each of the four clinical groups using univariate and multivariate(More)
Of a total of 1561 patients registered in the Intergroup Rhabdomyosarcoma Study (IRS) as of May 1983, 78 patients (5%) were younger than 1 year of age. These infants did not differ from the older children (1-20 years of age) in male/female ratio, clinical grouping, or survival rates. Infants younger than 1 year of age had a significantly greater frequency(More)
This article reports on the diagnostic features, radiographic findings, staging, operative management, treatments, and treatment results for 95 children (mean age, 10 years) with paratesticular sarcoma; they were treated on the Intergroup Rhabdomyosarcoma Study (IRS) I and II protocols. Embryonal rhabdomyosarcoma (RMS) was the most common histologic subtype(More)
A review of 1415 patients without distant metastasis from the Intergroup Rhabdomyosarcoma Study (IRS) I and II revealed an overall 10% incidence of identified lymphatic spread at diagnosis, whereas 81 of 592 children with localized rhabdomyosarcoma who had grossly complete resection (and therefore with more complete pathologic data) had histologically(More)
The need for a pretreatment staging system to accurately assess programs of therapy for the various sites and stages of childhood rhabdomyosarcoma has become apparent as detailed analyses of many factors affecting prognosis and treatment choices have been accomplished through the national cooperative trial, the Intergroup Rhabdomyosarcoma Study (IRS).(More)
Forty-two children, 6 months to 17 years of age with newly diagnosed soft-tissue sarcomas (gross residual or metastatic), were treated according to either of two pilot protocols that included intensive chemotherapy before irradiation. Vincristine, actinomycin D, cyclophosphamide, and doxorubicin were used in various combinations with cisplatin alone(More)
Children with rhabdomyosarcoma (RMS) (1461 total cases) were included in two prospective, randomized protocols conducted by the Intergroup Rhabdomyosarcoma Study (IRS) Committee from November 1972 to June 1983. Treatment assignment was determined by extent of tumor at diagnosis (clinicopathologic group) and not by primary site. Accordingly, 127 patients(More)
