Active clinical trials for "Leukemia, Myelomonocytic, Juvenile"

In this trial, the investigators will test the combination of escalating doses of chemotherapy (starting at relatively low dose) with lenalidomide in intermediate-2-or high risk MDS and AML with del 5 q31. It is hoped that this combined therapy will further increase response rate in intermediate-2-or high risk MDS and AML with del 5 q31, without major toxicity in comparison to historical results obtained with chemotherapy alone in the same subset of patients.

Long-term follow-up studies have demonstrated significant late toxicities of total body irradiation (TBI), which are most marked in children radiated at a young age. Growth failure, decline in cognitive function, and endocrine abnormalities have all been described. Good outcomes can be achieved with alkylating agents only as a preparative regimen. This plan will use a combination of busulfan and cyclophosphamide (Bu/Cy) with or without antithymocyte globulin (ATG) to reduce the late toxicities of therapy that includes TBI.

5-azacytidine treatment prolongs survival in patients with myelodysplastic syndrome (MDS), but does not cure the disease. Allogeneic stem cell transplantation is a curative treatment option but is associated with a high risk treatment-related morbidity and mortality. In the current trial allogeneic stem cell transplantation will be compared to 5-azacytidine only treatment according to donor availability in elderly patients with MDS (55-70 years).

This pilot clinical trial studies mechanical stimulation in preventing bone density loss in patients undergoing donor stem cell transplant. Mechanical stimulation may limit, prevent, or reverse bone loss, increase muscle and cardiac performance, and improve overall health

The purpose of this study is to assess the safety and effectiveness in the real-world setting among participants who are treated with Azacitidine in accordance with the China Product Label.

This study is a non-interventional, specimen collection translational study to evaluate vitamin C levels in the peripheral blood of Acute Myeloid Leukemia (AML), Myelodysplastic Syndrome (MDS), or Chronic Myelomonocytic Leukemia (CMML) patients.

This randomized phase III trial is studying how well Caphosol rinse works in preventing mucositis in young patients undergoing autologous or donor stem cell transplant. Supersaturated calcium phosphate (Caphosol) rinse may be able to prevent mucositis, or mouth sores, in patients undergoing stem cell transplant.

RATIONALE: Infection prophylaxis and management may help prevent cytomegalovirus (CMV) infection caused by a stem cell transplant. PURPOSE:This clinical trial studies infection prophylaxis and management in treating cytomegalovirus infection in patients with hematologic malignancies previously treated with donor stem cell transplant.

Myelodysplastic syndromes (MDS) constitute a heterogeneous group of clonal bone marrow neoplasms that predominate in the elderly, with a median age at diagnosis of 70 years. MDS are characterized by peripheral blood cytopenia and morphologic dysplasia for one or more hematopoietic cell lineage, reflecting ineffective hematopoiesis. The diagnostic work-up of MDS includes a bone marrow aspirate and biopsy, which is an invasive procedure, for cytomorphologic and cytogenetic evaluations. Because the prevalence of disease is lower than 20% in subjects referred for suspected MDS, many patients are exposed to unnecessary bone marrow aspiration-related discomfort and harms. An objective assay is highly desirable for accurately ruling out MDS based on peripheral blood samples, which may obviate the need for invasive bone marrow aspiration and biopsy in patients with negative results. Few studies have investigated the value of peripheral blood flow cytometric analysis for the diagnosis of MDS and/or chronic myelomonocytic leukemia (CMML). Although promising, these studies lacked replication of their results, used a case-control design, which was prone to spectrum bias, or yielded imprecise diagnostic accuracy estimates due to relatively limited sample sizes. Anecdotal evidence supports the potential of flow cytometric analysis of peripheral blood neutrophil myeloperoxidase expression for the diagnosis of MDS and CMML. Myeloperoxidase is an enzyme synthetized during myeloid differentiation that constitutes the major component of neutrophil azurophilic granules. Myeloperoxidase expression may reflect neutrophil hypogranulation, which is a classical although subjective dysplastic feature of MDS. Flow cytometric analysis of myeloperoxidase expression in bone marrow neutrophil granulocytes has been used for discriminating low versus high grade MDS. Yet a study reporting on the accuracy of flow cytometric analysis of peripheral blood neutrophil myeloperoxidase expression for the diagnosis of MDS is still lacking, to our knowledge. In this study, the investigators hypothesize that flow cytometric analysis of neutrophil myeloperoxidase expression in peripheral blood may accurately rule out MDS and obviate the need for bone marrow aspiration and biopsy, with sensitivity approaching 100%, in routine practice. In this observational diagnostic accuracy study, burden will be null for recruited patients. No specific intervention is assigned to participants. All diagnostic testing, procedures, and medication ordering are performed at the discretion of attending physicians. Flow cytometry analysis of peripheral blood neutrophil myeloperoxidase expression will not require additional blood sample. A test result will have no impact on patient management. No follow-up visits are planned in this cross-sectional study.

Post-authorisation observational study to assess the evolution in normal clinical practice of patients recently diagnosed with myelodysplastic syndrome (MDS) or chronic myelomonocytic leukaemia (CMML), depending on the moment when active treatment is initiated. Subjects will be recruited from approximately 50 haematology sites in Spain.
