The pharmacogenetics of methotrexate (MTX) was investigated in a large cohort of pediatric patients with acute lymphoblastic leukemia (ALL). Four hundred ninety-nine children with ALL from the ALL-BFM (Berlin-Frankfurt-Münster) 2000 trial who received 1996 courses of MTX at 5 g/m(2) were genotyped for 8 single nucleotide polymorphisms in 5 candidate genes(More)
Trial ALL-BFM 90 was designed to improve outcome in patients with childhood acute lymphoblastic leukemia (ALL) by using a reduced treatment regimen. Patients were stratified into a standard-risk group (SRG), a medium-risk group (MRG), both defined by adequate early treatment response; and a high-risk group (HRG), defined by inadequate response to the(More)
In trial ALL-BFM 86, the largest multicenter trial of the Berlin-Frankfurt-Münster (BFM) study group for childhood acute lymphoblastic leukemia (ALL), treatment response was used as an overriding stratification factor for the first time. In the previous trial ALL-BFM 83, the in vivo response to initial prednisone treatment was evaluated prospectively. A(More)
Secondary neoplasms (SNs) represent serious late complications after successful treatment of malignant diseases. To evaluate the rate and type of SNs after Berlin-Frankfurt-Münster (BFM) treatment in children with acute lymphoblastic leukemia (ALL), we analyzed the data from the BFM database and the German Childhood Cancer Registry (GCCR). Between April(More)
The purpose of our study was to investigate the efficacy of an acute lymphoblastic leukemia (ALL)-type treatment with moderate-dose, prophylactic cranial irradiation and without local radiotherapy for childhood T-cell lymphoblastic lymphoma (T-LBL). From April 1990 to March 1995, 105 evaluable patients, 1.1 to 16.4 years of age, with T-LBL were enrolled in(More)
Between 1981 and 2000, 6609 children (<18 years of age) were treated in five consecutive trials of the Berlin-Frankfurt-Münster (BFM) study group for childhood acute lymphoblastic leukemia (ALL). Patients were treated in up to 82 centers in Germany, Austria and Switzerland. Probability of 10-year event-free survival (EFS) (survival) improved from 65% (77%)(More)
The Associazione Italiana di Ematologia Oncologia Pediatrica and the Berlin-Frankfurt-Münster Acute Lymphoblastic Leukemia (AIEOP-BFM ALL 2000) study has for the first time introduced standardized quantitative assessment of minimal residual disease (MRD) based on immunoglobulin and T-cell receptor gene rearrangements as polymerase chain reaction targets(More)
PURPOSE To improve outcome in high-risk patients, high-dose cytarabine and mitoxantrone (HAM) was introduced into the treatment of children with acute myelogenous leukemia (AML) in study AML-BFM 93. Patients were randomized to HAM as either the second or third therapy block, for the purpose of evaluation of efficacy and toxicity. PATIENTS AND METHODS A(More)
Pediatric acute lymphoblastic leukemia (ALL) is a malignant disease resulting from accumulation of genetic alterations. A robust technology, single nucleotide polymorphism oligonucleotide genomic microarray (SNP-chip) in concert with bioinformatics offers the opportunity to discover the genetic lesions associated with ALL. We examined 399 pediatric ALL(More)
The trial ALL-BFM 95 for treatment of childhood acute lymphoblastic leukemia was designed to reduce acute and long-term toxicity in selected patient groups with favorable prognosis and to improve outcome in poor-risk groups by treatment intensification. These aims were pursued through a stratification strategy using white blood cell count, age,(More)
