The prognosis of germinal center-derived B-cell (GCB) lymphomas, including follicular lymphoma and diffuse large-B-cell lymphoma (DLBCL), strongly depends on age. Children have a more favorable outcome than adults. It is not known whether this is because of differences in host characteristics, treatment protocols, or tumor biology, including the presence of(More)
The majority of lymphoblastic (precursor cell) neoplasms presents as leukemias. Consequently, the guidelines for lineage determination and subtyping of precursor cell neoplasms were primarily established for flow cytometry methods. Large-scale studies of nonleukemic lymphoblastic lymphomas are lacking so far. We analyzed a large series of pediatric patients(More)
PURPOSE To evaluate risk factors for outcome in children and adolescents with relapse of anaplastic large-cell lymphoma (ALCL) after comparable first-line therapy. PATIENTS AND METHODS We analyzed a population-based cohort of 74 children with relapsed ALCL after Berlin-Frankfurt-Muenster-type first-line therapy between April 1990 and December 2003. The(More)
UNLABELLED Background Pediatric follicular lymphoma has recently been recognized as a novel variant of follicular lymphoma in the World Health Organization classification of lymphomas. Given the rarity of the disease, histopathological and genetic data on this type of lymphoma are still scarce. DESIGN AND METHODS We analyzed 25 cases of pediatric(More)
PURPOSE The prognostic value of pathologic characteristics of childhood ALK-positive anaplastic large-cell lymphomas (ALCL), such as histologic subtypes, immunophenotype, and presence of the t(2;5) translocation or its variants, was assessed. PATIENTS AND METHODS All 375 patients with systemic ALK-positive ALCL included in an international trial launched(More)
Diffuse large B-cell lymphoma (DLBCL) in adults is a heterogeneous disease. Biologic subgroups of DLBCL with a favorable prognosis (germinal center B-cell-like, GCB) and with a poor prognosis (activated B-cell-like, ABC) have been defined by gene expression profiling and can be distinguished by immunohistochemistry. In contrast to their adult counterparts,(More)
We analysed the impact of age and gender on biology and outcome of 2084 patients diagnosed with non-Hodgkin lymphoma (NHL) between October 1986 and December 2002 and treated according to the Berlin-Frankfurt-Münster (BFM) multicentre protocols NHL-BFM-86, -90 and -95. Median age at diagnosis was 8.0 years for 97 precursor B-lymphoblastic lymphoma (pB-LBL)(More)
Age-related differences in the distribution, biology and treatment response of non-Hodgkin's lymphoma (NHL) in adolescents remain to be elucidated. The current analyses present clinical parameters and outcomes of adolescents treated in pediatric NHL-BFM trials. Patients were stratified by histological subtype: lymphoblastic lymphoma (LBL); mature B-NHL,(More)
In the Non-Hodgkin Lymphoma-Berlin-Frankfurt-Münster 95 (NHL-BFM95) study, we tested by randomization whether for patients with B-cell neoplasms methotrexate as intravenous infusion over 4 hours (MTX-4h) is not inferior to, but less toxic than, a 24-hour intravenous infusion (MTX-24h). Second, we investigated against the historical control of study(More)
Mature (peripheral) T-cell lymphoma (PTCL) other than anaplastic large cell lymphoma is a heterogeneous group of diseases and exceedingly rare in children and adolescents. Survival rates range between 46% and 85%. This study reports the disease characteristics, treatment and outcome of all patients with the diagnosis of mature TCL registered in the(More)
