Filter by:Toxicities related to pediatric cancer treatment can lead to significant illness, organ damage, treatment delays, increased health care cost, and decrease in quality of life. Such toxicities are largely due to tissue damage sustained by chemotherapy, and strategies designed to limit such cellular damage to normal tissues may reduce therapy-related morbidity and mortality. In addition to their in vitro and in vivo anti-cancer effects, naturally occurring soy isoflavones have anti-inflammatory and anti-oxidant properties, and have been shown to reduce side effects of therapy in adult oncology clinical trials. This study will examine the effect of genistein, the major isoflavone component in soybeans and the most extensively studied of the soy isoflavones, on short-term side effects of myelosuppressive chemotherapy in pediatric cancer patients. Subjects will be randomized to receive either: a) 30 mg genistein daily throughout chemotherapy Cycles 1 and 2 and placebo during chemotherapy Cycles 3 and 4; or b) placebo daily during chemotherapy Cycles 1 and 2 and 30 mg genistein daily during chemotherapy Cycles 3 and 4. Investigators hypothesize that subjects will have fewer short-term therapy-related side effects during cycles of chemotherapy given in conjunction with genistein supplementation than cycles given with placebo.
The investigators propose a new antitumor cell therapy for treating childhood refractory solid tumours. The aim of this study is explore the graft versus tumour effect mediated by allogenic natural killer cells (NKs). NK cell alloreactivity can be predicted by donor killer immunoglobulin-like receptors (KIRs) and human leukocyte antigen (HLA) class I alleles mismatch. Cells without an inhibitory HLA ligand may trigger natural killer cell activation and elimination of those target cells. Reduced risk of relapsed has been described in malignant cancer after haploidentical stem cell transplantation when HLA ligands against the inhibitory KIRs present in the donor were absent in the recipient (KIR-HLA receptor-ligand mismatch). NK alloreactivity could also be obtained by Natural Killer Receptor (NCR), Toll-Like-Receptors (TLRs) and NKG2D receptor stimulation mediated by cytokines or tumour cell lines. This will be an open, non randomized, Phase I/II clinical trial, with a double objective: therapeutic exploratory. The investigators aim at studying safety and efficacy of haploidentical stem cell transplantation for the treatment of these malignancies with no cure known. Patients will receive an haploidentical stem cell transplantation, followed by IL-15 stimulated NK cells infusion one month after transplantation. Efficacy of the procedure will be evaluated with up-to-date radiological techniques, molecular studies and functional assays.
