Filter by:The present therapy intends to be an homogeneous treatment for AML patients based on a pretreatment with hydroxiurea plus an induction therapy with the standard arm with Daunorubicine as according to EORTC-GIMEMA AML10 study. The post-remissional treatment is based on transplant with HLA compatible donor is foreseen for all patients and autologous transplant for those without HLA compatible donor available.
Newly diagnosed pediatric patients (age < 19 years) with bcr-abl-positive CML will be treated with imatinib. Serial monitoring of treatment response is performed in one month intervals during the first three months of treatment and in three months intervals thereafter. Patients with non-response, poor response (either molecular, cytogenetic, or hematologic non-/poor response) or progress of the disease while under imatinib treatment will stop imatinib and undergo stem cell transplantation. All responders to imatinib treatment with an HLA matched donor will undergo stem cell transplantation not later than 2 years after diagnosis.
RATIONALE: Giving chemotherapy, such as busulfan, fludarabine, and melphalan, before a donor umbilical cord blood stem cell transplant helps stop the growth of abnormal or cancer cells and prepares the patient's bone marrow for the stem cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving cyclosporine and mycophenolate mofetil may stop this from happening. PURPOSE: This phase II trial is studying how well combination chemotherapy followed by a donor umbilical cord blood transplant works in treating infants with high-risk acute leukemia or myelodysplastic syndromes.
The purpose of this study is to evaluate the incidence of neutrophil engraftment after transplantation of one or two cord blood units meeting a predetermined total minimum cell dose of 2.0 x 10 to the seventh total nucleated cell (TNC)/kg.
This study will investigate the efficacy and tolerability of a short (6 months) high dose therapy followed by a standard dose compared to a continuous treatment with a standard dose of imatinib (Glivec®) in pretreated Philadelphia chromosome- positive (Ph+)/BCR-ABL+ CML patients in chronic phase.
Primary Objective: A. To determine whether stable allogeneic hematopoietic engraftment can be safely established in patients receiving a non-myeloablative allogeneic SCT from a matched sibling donor, with fludarabine and low-dose TBI, with pre- and post-transplant immunosuppression with tacrolimus and MMF. B. To evaluate the incidence of grade II-IV GVHD associated with this treatment.
The study is controlled and randomized in Philadelphia-positive chronic myeloid leukemia (Ph+ CML) patients with complete cytogenetic response after more than one year of imatinib therapy. The aim is to explore a possible benefit in the addition of peg-interferon (Peg-IFN) to imatinib, in terms of the rate of achievement, molecular remission, and response duration.
Primary Objectives: This a pilot project to determine the feasibility of the preemptive CD8+ depleted T-cell donor lymphocyte infusion (DLI) in: - Reducing the incidence of graft versus host disease (GVHD) based on standard classification of acute and chronic GVHD - Improving hte disease remission rate in comparison with our previous study results. Secondary Objectives: - To investigate the impact of CD8+ depleted T-cell DLI in hematopoietic chimerism, and immunologic recovery of transplant patients.
The allograft of marrow in its technique of reference (myélo-ablative (MA) condition by cyclophosphamide and total body irradiation (TBI) with strong amounts) therapeutic is recognized acute myeloid leukaemia (AML) of the adult for the patients of less than 55 years, because it offers chances of cure higher than chemotherapy or the auto-graft. However, mortality related to the traditional graft is approximately 30% to 1 year. The recent use of the non-myélo-ablative graft (NMA), in which the anti-leukaemia effect rests exclusively on the allogenic effect "graft-versus-leukaemia" makes it possible to obtain among patients of more than 55 years in complete reemission (CR), survivals without relapses comparable with the traditional allograft among patients of more than 35 years. The major interest of NMA graft is to reduce early mortality related to the graft. This reduction should be all the more significant as the patient is younger, and thus bring to a better survival. There is not, at the present hour, of prospective comparative study of the two procedures of graft. Taking into account the results observed after NMA graft among patients of more than 55 years, and taking into account the toxicity of the standard graft between 35 and 55 years, it is essential to now compare the 2 approaches among patients who do not have a counter-indication for one or the other, in the age bracket where the toxicity of the traditional graft is highest.
In malignant or neoplastic disease, angiogenesis is defined as the generation of new capillaries from preexisting blood vessels, e.g. by sprouting or by intusseption. Through the pioneering work of Folkman, it was recognized that angiogenesis plays an important role in tumor development, progression, and metastasis. It is also conceivable that there are forms or developmental stages of leukemia, multiple myeloma, or lymphomas that will progress independently of angiogenesis. Synthesis of angiogenesis activators, such as vascular endothelial growth factor (VEGF) and other angiogenic factors, such as basic fibroblast growth factor (bFGF), has been demonstrated for leukemia cells, non-Hodgkin’s lymphoma, and myeloma cells. Microvessel density is also significantly elevated over normal controls with progressive increases according to the stages of myelodysplastic syndrome. Increased microvessel density (MVD) in the bone marrow was found in patients with multiple myeloma in comparison to normal controls and increased MVD is an adverse prognostic marker in multiple myeloma. However, the functional status of the blood vessel (e.g. permeability) cannot be determined by the above mentioned methods.
