BACKGROUND Children with high-risk acute lymphoblastic leukemia (ALL) who have a slow response to initial chemotherapy (more than 25 percent blasts in the bone marrow on day 7) have a poor outcome despite intensive therapy. We conducted a randomized trial in which such patients were treated with either an augmented intensive regimen of post-induction(More)
Leukemic cells from a significant number of children with acute lymphoblastic leukemia (ALL) express protein antigens characteristic of both lymphoid and myeloid cells, yet the clinical significance of this immunophenotype has remained controversial. In the current study, we have determined relationships between myeloid antigen expression and treatment(More)
Cancer is a significant health problem in the adolescent and young adult population. Confusion exists within the field of pediatric oncology with respect to the definition of childhood cancer, since most population-based incidence studies define childhood cancer on the basis of age alone. We recommend that the scope of pediatric oncology include the study(More)
Ikaros, a zinc finger-containing DNA-binding protein, is required for normal lymphocyte development. Germ-line mutant mice that express only non-DNA binding dominant-negative "leukemogenic" Ikaros isoforms lacking critical NH2-terminal zinc fingers develop an aggressive form of T-cell leukemia. We studied Ikaros gene expression in leukemic cells from 18(More)
Leukemic cells from bone marrow (BM) of 17 infants and 127 children with newly diagnosed ALL, as well as fetal liver and BM and normal infant BM samples, were analyzed for presence of a t(4;11) translocation using standard cytogenetic techniques and expression of an MLL-AF4 fusion transcript using standard reverse transcriptase-polymerase chain reaction(More)
PURPOSE A randomized trial designed to compare mechlorethamine, vincristine, procarbazine, and prednisone (MOPP)/doxorubicin, bleomycin, vinblastine, and daccarbazine (ABVD) (regimen A) with ABVD plus low-dose regional (extended-field) radiation therapy (EF RT) (regimen B) for the treatment of children and adolescents with stages III and IV Hodgkin's(More)
We found a marked variation in BCL-2 oncoprotein expression levels of primary leukemic cells from 338 children with newly diagnosed acute lymphoblastic leukemia (ALL). None of the high-risk features predictive of poor treatment outcome in childhood ALL, such as older age, high white blood cell (WBC) count, organomegaly, T-lineage immunophenotype, ability of(More)

The inhibition of specific SH2 domain mediated protein-protein interactions as an effective chemotherapeutic approach in the treatment of diseases remains a challenge. That different conformations of peptide-ligands are preferred by different SH2 domains is an underappreciated observation from the structural analysis of phosphotyrosine peptide binding to(More)
