BACKGROUND Extracorporeal photochemotherapy (ECP) gives positive results in the management of graft-versus-host disease (GVHD), but in children, specific difficulties can outweigh this benefit. These difficulties must be taken into consideration when establishing a standardized reproducible procedure for implementation under a quality management plan. (More)
PURPOSE To evaluate the efficacy of vinblastine for relapsed/refractory anaplastic large-cell lymphoma (ALCL). PATIENTS AND METHODS Data were reviewed on all 36 patients included prospectively in the French database for pediatric ALCL who were treated with vinblastine (6 mg/m(2)/wk) for resistant primary disease (one), a first relapse (15), or subsequent(More)
New concepts of allogeneic hematopoietic SCT (allo-HSCT) for neuroblastoma and other solid tumors do not rely on escalation of chemotherapy intensity and tumor load reduction but rather on a graft-vs-tumor effect. At this point, this is still an investigational and unusual application of allogeneic transplant, with 78 neuroblastoma patients reported to the(More)
Although worldwide experience with extracorporeal photochemotherapy (ECP) for GvHD treatment has grown enormously over the past decade, only a few pediatric centers have experience with ECP. Studies reporting clinical outcome in children with GvHD treated by ECP comprises a very limited number of patients with only few information described. This review(More)
Juvenile myelomonocytic leukemia (JMML) is a rare and severe myelodysplastic and myeloproliferative neoplasm of early childhood initiated by germline or somatic RAS-activating mutations. Genetic profiling and whole-exome sequencing of a large JMML cohort (118 and 30 cases, respectively) uncovered additional genetic abnormalities in 56 cases (47%). Somatic(More)
Little information is available on erythrocytapheresis in children with sickle cell disease, and no comparison has ever been made with manual exchanges in a long-term blood exchange program. We matched a historical cohort of five patients who received 60 erythrocytapheresis procedures with five who received 124 manual exchanges. Long-term(More)
BACKGROUND Allogeneic haematopoietic stem cell transplantation (allo-SCT) may provide donor cytotoxic T cell-/NK cell-mediated disease control in patients with rhabdomyosarcoma (RMS). However, little is known about the prevalence of graft-vs-RMS effects and only a few case experiences have been reported. METHODS We evaluated allo-SCT outcomes of 30(More)

PURPOSE Langerhans cell histiocytosis (LCH) is an inflammatory myeloid neoplasia with a broad spectrum of clinical manifestations and outcomes in children. The somatic BRAF(V600E) mutation occurs frequently, but clinical significance remains to be determined. PATIENTS AND METHODS BRAF(V600E) mutation was investigated in a French LCH cohort. We analyzed(More)
There is little data available regarding children and adolescents with Hodgkin lymphoma (HL) who relapse after combined-modality treatment, even though they have a substantial chance of cure. The purpose of this national retrospective study was to evaluate the outcome of patients with recurrent/refractory HL and determine adverse prognostic factors. From(More)
