PURPOSE To determine the response rate of the combination of cyclophosphamide and topotecan in pediatric patients with recurrent or refractory malignant solid tumors. PATIENTS AND METHODS A total of 91 pediatric patients, 83 of whom were fully assessable for response and toxicity, received cyclophosphamide (250 mg/m2/dose) followed by topotecan (0.75(More)
Human genetic variation contributes to differences in susceptibility to HIV-1 infection. To search for novel host resistance factors, we performed a genome-wide association study (GWAS) in hemophilia patients highly exposed to potentially contaminated factor VIII infusions. Individuals with hemophilia A and a documented history of factor VIII infusions(More)
Juvenile myelomonocytic leukemia (JMML) is a myeloproliferative neoplasm (MPN) of childhood with a poor prognosis. Mutations in NF1, NRAS, KRAS, PTPN11 or CBL occur in 85% of patients, yet there are currently no risk stratification algorithms capable of predicting which patients will be refractory to conventional treatment and could therefore be candidates(More)
PURPOSE To determine the outcomes, with particular attention to toxicity, of children with Down syndrome (DS) and acute myeloid leukemia (AML) treated on Pediatric Oncology Group (POG) protocol 9421. PATIENTS AND METHODS Children with DS and newly diagnosed AML (n = 57) were prospectively enrolled onto the standard-therapy arm of POG 9421 and were(More)
BACKGROUND Treatment choice in pediatric immune thrombocytopenia (ITP) is arbitrary, because few studies are powered to identify predictors of therapy response. Increasingly, rituximab is becoming a treatment of choice in those refractory to other therapies. METHODS The objective of this study was to evaluate univariate and multivariable predictors of(More)
PURPOSE Patients with Ehlers-Danlos syndrome (EDS), especially types IV, VI, and VIII, are at increased risk of bleeding, and most do not have specific hemostatic deficiencies that would be amenable to replacement therapy. We have investigated the ability of DDAVP (desmopressin acetate) to control bleeding in EDS. PATIENTS AND METHODS Two children with(More)
PURPOSE To present two patients as illustrations of the risk of developing secondary acute myelogenous leukemia (sAML) when theoretically safe doses of etoposide (VP-16) are used. PATIENTS AND METHODS Patient no. 1 was a 15-year-old white girl diagnosed with stage IIa Hodgkin's disease. She was treated with a combination of vincristine, doxorubicin,(More)
PURPOSE Prognosis is poor for Ewing sarcoma patients with metastasis at diagnosis. We intensified a five-drug therapy (ifosfamide, etoposide alternated with vincristine, doxorubicin, and cyclophosphamide) using filgrastim but not stem-cell support. We studied topotecan alone and combined with cyclophosphamide in therapeutic windows before the five-drug(More)
HIV-1-specific cell-mediated cytotoxicity (CMC) is a form of antibody-dependent cellular cytotoxicity (ADCC) in which HIV-1-specific antibodies arm NK cells directly to become cytotoxic for targets bearing HIV-1 antigenic determinants. This non-MHC-restricted cytotoxic activity is present in early stages of disease and declines markedly with disease(More)
