Modern treatment strategies have improved the prognosis of childhood ALL; however, treatment still fails in 25-30% of patients. Further improvement of treatment may depend on the development of targeted therapies. mTOR kinase, a central mediator of several signaling pathways, has recently attracted remarkable attention as a potential target in pediatric(More)
The Langerhans cell histiocytosis (LCH) in children is relatively rare and the long-term analysis of therapy results has not been done yet in Hungary. The aim of this study was to investigate the incidence, clinical features, prognostic risk factors, and treatment results of children's LCH in Hungary in a 20-year period. Children less than 18 years of age(More)
To develop an effective immunotherapy for B-lineage acute lymphoblastic leukemia (ALL), bispecific monoclonal antibodies (bsAb) were raised by cell fusion of two hybridoma cell lines secreting CD3 and CD19 antibodies. The resulting bispecific antibody contains two different specificities within a single antibody molecule. One binding site (CD3) activates(More)
Targeting signaling pathways is an attractive approach in many malignancies. The PI3K/Akt/mTOR pathway is activated in a number of human neoplasms, accompanied by lower overall and/or disease free survival. mTOR kinase inhibitors have been introduced in the therapy of renal cell carcinoma and mantle cell lymphoma, and several trials are currently underway.(More)
We investigated whether an altered individual glucocorticoid sensitivity due to particular glucocorticoid receptor single-nucleotide polymorphisms (SNPs) (N363S, ER22/23EK, and Bcl-1) influences the susceptibility to steroid-related toxicities, prognostic factors, and survival rates in children with acute lymphoblastic leukemia. In total, 346 pediatric(More)
In spite of the improved efficacy of therapy, it still fails in 15–20 % of childhood acute lymphoblastic leukemia (ALL) patients. Recently, altered expression of certain miRNAs (miRs) have been described in ALL with potential effect on prognosis. Presence of certain miRs (miRNA-16, −21, −24, −29b, −128b, −142-3p, −155, −223) was characterized in human(More)
OBJECTIVES The use of anthracyclines are limited by their cardiotoxic side effects (first of all congestive cardiomyopathy). In this study we analyzed the anthracycline-induced cardiotoxicity and the possible preventive role of dexrazoxane in children. PATIENTS 158 anthracycline-treated long-term survivors could be analyzed. Sixty-one children received(More)
Data on clinical features and outcome in pediatric follicular lymphoma (pFL) are scarce. The aim of this retrospective study including 13 EICNHL and/or i-BFM study group members was to assess clinical characteristics and course in a series of 63 pFL patients. pFL was found to be associated with male gender (3:1), older age (72 % ≥10 years old), low serum(More)
Primary genetic abnormalities of leukemia cells have important prognostic significance in childhood acute leukemia. In the last two years 30 newly diagnosed or recurrent childhood ALL bone marrow samples were analyzed for chromosomal abnormalities with conventional G-banding and interphase-fluorescence in situ hybridization (I-FISH) using probes to detect(More)
Children and adolescents with pre-existing conditions such as DNA repair defects or other primary immunodeficiencies have an increased risk of non-Hodgkin lymphoma. However, large-scale data on patients with non-Hodgkin lymphoma and their entire spectrum of pre-existing conditions are scarce. A retrospective multinational study was conducted by means of(More)
