PURPOSE The study goal was to improve outcome in children with rhabdomyosarcoma by comparing risk-based regimens of surgery, radiotherapy (RT) and chemotherapy. PATIENTS AND METHODS Eight hundred eighty-three previously untreated eligible patients with nonmetastatic rhabdomyosarcoma entered the Intergroup Rhabdomyosarcoma Study-IV (IRS-IV) (1991 to 1997)(More)
BACKGROUND There is a need to develop a single prognostically significant classification of rhabdomyosarcomas (RMS) and other related tumors of children, adolescents, and young adults which would be a current guide for their diagnosis, allow valid comparison of outcomes between protocols carried out anywhere in the world, and should enhance recognition of(More)
A specific chromosomal abnormality, t(2;13)(q35;q14), was discovered in five cases of advanced rhabdomyosarcoma. It was identified directly in cells that had metastasized from bone marrow in one patient and in xenografts derived from the tumors of four other patients. The translocation was not restricted by histologic subtype, but was found in cases(More)
Ectomesenchymomas (EM) are rare malignant neoplasms usually consisting of rhabdomyosarcoma (RMS) with a neural component. Only 21 cases have been previously reported. Here we extend the clinicopathologic spectrum of EM by describing our findings in 15 cases. Only 5 patients were infants; 10 were < or =3 years old and 5 were > or =6 years old. No male(More)
PURPOSE One hundred thirty of 2,792 patients (5%) registered on three Intergroup Rhabdomyosarcoma Study clinical trials (IRS-I, -II, and -III) from 1972 to 1991 had an extraosseous Ewing's sarcoma (EOE). We report here the results of multimodality therapy for this tumor. PATIENTS AND METHODS The 130 patients were less than 21 years of age; 70 (54%) were(More)
Neonatal rhabdomyosarcoma is rare, and the characteristics and optimal therapy for patients with this condition have not been well described. Of 3,217 eligible patients entered in the Intergroup Rhabdomyosarcoma Study (IRS), 14 were less than 30 days old at the time of diagnosis. Among these patients, male gender, Caucasian race, caudal tumors, and(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)
Because of the rarity of pediatric nonrhabdomyosarcomatous soft tissue sarcomas, it is difficult to test standardized treatment protocols for individual tumor entities. Grading has been used successfully to predict outcome of adult sarcomas, but pediatric soft tissue tumors display a notable difference in clinical behavior when compared to older patients.(More)
From July 1972 through September 1984, 8 of 44 children diagnosed as having primary malignant hepatic tumors, who were treated at St. Jude Children's Research Hospital, had undifferentiated (embryonal) sarcoma (five patients) or rhabdomyosarcoma (three patients). The natural history and response to multimodal therapy of these rare tumors are described. The(More)
