Filter by:Adult acute lymphoblastic leukemia treatment approaches relie on risk stratification, including cytogenetics. We want to study at diagnosis several blast cells parameters on frozen samples of GRAALL protocols enrolled patients: 1. A CD45-DNA double staining analysed by flow cytometry will allow mesurement for each blastic clone of DNA ploidy, percentage of cells in S-phase, CD45 fluorescence index. 2. The proteine P16 metabolic way, involved in cell cycle regulation, will be studied by Western Blot analysis. The comparison between these parameters, and main haematological data, will be followed by a prognostic analysis, based on blast corticosensibility in vivo, chimiosensibility, complete remission, and survival. Combination of the studied parameters will allow to appreciate a clonal diversity. This will help to predict, at diagnosis, high probability of resistance to treatment.
This is a pilot study to demonstrate that the modified LMB-89 treatment regimen for children with newly diagnosed small noncleaved cell NHL, large cell NHL (B-cell), and B-cell acute lymphoblastic leukemia can be delivered in this setting with acceptable toxicity.
The main purpose of this study is to find out which form of asparaginase (the native E. coli/Erwinia) or PEG-asparaginase) is more effective during induction treatment for children with acute lymphoblastic leukemia that has come back after treatment (relapsed) or is resistant to treatment (refractory)
The main purpose of this study is to find out if radiation to the central nervous system (CNS) can be safely omitted with early intensification of chemotherapy and chemotherapy given directly to the CNS. Another purpose is to find out if survival of children with ALL can be improved with risk-directed therapy given on this protocol.
This is an international multicenter open label randomized phase III trial in children with relapsed and refractory acute myeloid leukemia (AML) such a disease. The main purpose of this study is to determine the efficacy and toxicity of liposomal daunorubicin when added to fludarabine, ara-C and G-CSF(FLAG) in children with relapsed and refractory AML.
This is a multi-center trial for rasburicase in children at high risk of tumor lysis syndrome who have a history of asthma/atopy. The main purpose of this study is to establish the safety of this drug in patients with a history of asthma or severe allergies.
Research studies have shown that children who are long-term survivors of childhood leukemia may be at greater risk for early bone loss called osteoporosis. This bone loss may lead to a greater risk of broken bones and other spine and bone problems. However, researchers still do not know much about how frequently this long-term side effect may occur and how severe the problem is. St. Jude Children's Research Hospital researchers want to determine the frequency and severity of this side effect. They are also studying whether taking calcium and Vitamin D supplements can help children at risk for osteoporosis and if certain factors can be identified -- such as age at diagnosis, cancer treatments, or family history -- that may increase the chances of having osteoporosis. Researchers will take an x-ray study called quantitative computed tomography (QCT) to measure bone mineral density (BMD). The BMD is a measure of bone strength. If a subject's BMD falls below the average, he/she will be assigned to one of two groups. Subjects will be randomly assigned (like tossing a coin) to receive calcium and vitamin D pills. The other half will receive placebo pills that look like the calcium and vitamin D pills.
The main purpose of this study is to find out how well participants with relapsed or refractory ALL respond to treatment with an etoposide- and teniposide-based induction chemotherapy regimen and what the side effects are. Primary Objectives: - To estimate the response rate for patients with refractory or relapsed ALL. - To estimate the survival rate of patients with refractory or relapsed ALL treated with risk-directed therapy.
Blood and marrow stem cell transplant has improved the outcome for patients with high-risk hematologic malignancies. However, most patients do not have an appropriate HLA (immune type) matched sibling donor available and/or are unable to identify an acceptable unrelated HLA matched donor through the registries in a timely manner. Another option is haploidentical transplant using a partially matched family member donor. Although haploidentical transplant has proven curative in many patients, this procedure has been hindered by significant complications, primarily regimen-related toxicity including graft versus host disease (GVHD) and infection due to delayed immune reconstitution. These can, in part, be due to certain white blood cells in the graft called T cells. GVHD happens when the donor T cells recognize the body tissues of the patient (the host) are different and attack these cells. Although too many T cells increase the possibility of GVHD, too few may cause the recipient's immune system to reconstitute slowly or the graft to fail to grow, leaving the patient at high-risk for significant infection. This research project will investigate the use of particular pre-transplant conditioning regimen (chemotherapy, antibodies and total body irradiation) followed by a stem cell infusion from a "mismatched" family member donor. Once these stem cells are obtained they will be highly purified in an effort to remove T cells using the investigational CliniMACS stem cell selection device. The primary goal of this study will be to determine the rate of neutrophil and platelet engraftment, as well as the degree and rate of immune reconstitution in the first 100 days posttransplant for patients who receive this study treatment. Researchers will also study ways to decrease complications that may occur with a transplant from a genetically mismatched family donor.
