PURPOSE To determine the incidence, risk factors, and morbidity for osteonecrosis (ON) in children with acute lymphoblastic leukemia (ALL) treated with intensive chemotherapy including multiple, prolonged courses of corticosteroid. PATIENTS AND METHODS The occurrence of symptomatic ON was investigated retrospectively in 1, 409 children ages 1 to 20 years(More)
This article describes case studies of five children treated with vasopressin for refractory hypotension. In addition, physiology and pharmacology of vasopressin are reviewed in a comprehensive survey of the literature from 1966 until the present. In all five children, blood pressure increased immediately after vasopressin administration. The preliminary(More)

We investigated the anti-asparaginase antibody (Ab) and asparaginase enzymatic activity in the sera of 1,001 patients (CCG-1961) with high-risk acute lymphoblastic leukemia (HR-ALL). Patients received nine doses of native Escherichia coli asparaginase during induction. Half of rapid early responders (RER) were randomly assigned to standard intensity arms(More)
PURPOSE Thrombocytopenia has been reported in some children with severe iron deficiency anemia, but the validity of the association and the mechanism of the thrombocytopenia are not well established. Six children with severe iron deficiency and thrombocytopenia are described, and the literature is reviewed. PATIENTS AND METHODS Clinical, hematologic, and(More)
PURPOSE The specific aims of this study were to improve event-free survival (EFS) in patients with newly diagnosed nonmetastatic osteosarcoma of an extremity using the histologic response to neoadjuvant chemotherapy to determine postoperative chemotherapy; to evaluate a uniform histologic grading system that measures tumor response; and to identify patient(More)
We have studied 20 children with therapy-related myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML) who were 3 months to 16 years old at diagnosis of their primary neoplasm and 1 to 24 years old at diagnosis of their secondary neoplasm. The median interval from initial treatment for the first malignancy to diagnosis of therapy-related MDS or AML(More)
PURPOSE Children with acute lymphoblastic leukemia (ALL) and high hyperdiploidy (> 50 chromosomes) have improved outcome compared with other ALL patients. We sought to identify cytogenetic features that would predict differences in outcome within this low-risk subset of ALL patients. MATERIALS AND METHODS High-hyperdiploid ALL patients (N = 480) were(More)
PURPOSE Current standard therapy for children and adolescents with Hodgkin's disease includes combination chemotherapy and low-dose involved-field radiation (LD-IFRT). Because radiation may be associated with adverse late effects, the Children's Cancer Group (CCG) investigated whether radiation could be omitted in patients achieving a complete response to(More)
PURPOSE Nonrandom chromosomal translocations are frequently observed in pediatric patients with acute lymphoblastic leukemia (ALL). Specific translocations, such as t(4;11) and t(9;22), identify subgroups of B-lineage ALL patients who have an increased risk of treatment failure. The current study was conducted to determine the prognostic significance of(More)
