Active clinical trials for "Leukemia, Myeloid, Acute"

To detect SRSF2 gene mutation by polymerase chain reaction (PCR) in the two types of t-MDS/AML which recognized in the WHO classification. Association between SRSF2 gene mutation and the presence of other cytogenetic abnormalities in the two types of t-MDS/AML which recognized in the WHO classification, e.g. (Loss of chromosome 7 or del(7q), del(5q), isochromosome 17q, recurrent balanced chromosomal translocations involving chromosomal segments 11q23 (KMT2A, previously called MLL) or 21q22.1 (RUNX1), and PML-RARA). Relationship between SRSF2 gene mutation and cumulative dose, dose intensity, time of exposure and prognostic criteria (disease free survival, overall survival and disease course).

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.

Purpose: The purpose of this trial is to investigate whether a microfluidics assay can detect trace amounts of residual leukemia and predict relapse in acute myeloid leukemia (AML) patients in remission who have undergone allogeneic stem cell transplantation (SCT) or Induction and Consolidation Chemotherapy (ICC) at the North Carolina Cancer Hospital (NCCH). Procedures (methods): A total of 40 eligible subjects will be treated per standard of care with either SCT or induction and consolidation chemotherapy (ICC) based on the appropriate AML treatment paradigm for their disease. Peripheral blood (10 ml) for microfluidic chip analysis and possible Immune Monitoring Core Facility analysis will be collected along with routine lab draws prior to SCT. Patients in remission after SCT or those with confirmed remission by bone marrow biopsy after induction chemotherapy will be followed for 1 year; and peripheral blood (20 ml) will be collected to assess MRD by standard methods or by microfluidic chip analysis on a monthly basis. In addition, bone marrow biopsies will be performed at the end of consolidation (typically 5 months from remission), and at 1-year post remission in non-transplant patients. In transplanted patients, bone marrow biopsies will be collected at + 30 days, + 90 days, +180 days, and +360 days after SCT.

The purpose of this study is to investigate if a type of magnetic resonance imaging (MRI) scan of the bone marrow before the start of standard chemotherapy can predict complete remission of leukemia patients after the therapy. This type of MRI scan, called dynamic contrast-enhanced MRI (DCE-MRI), measures bone marrow blood flow. For those patients who do not achieve complete remission status after initial therapy and will be treated with additional therapy, the investigators are also interested in determining if the second MRI exam before the additional therapy can predict complete remission. If successfully tested, the MRI exam may be used in the future to help with early identification of patients who are unlikely to respond to standard chemotherapy. This will allow for a personalized therapeutic plan to be developed for these patients at an early stage and prevent them from being exposed to toxic and ineffective therapies.

This study will examine the risks of workplace exposure to benzene, a substance known to lead to cancer of the blood and possibly of the lungs. It is used widely in industries and is a contaminant in the environment. Researchers from the National Cancer Institute and the China Center for Disease Control (formerly Chinese Academy of Preventive Medicine) had done previous studies of workers in manufacturing industries in China of people who worked at least 1 day from 1972 to 1987 in 12 cities in that country. Data were collected of approximately 75,000 workers exposed to benzene and 35,000 who were not, with the purpose of investigating the relationship between benzene exposure and cancer risk. For workers exposed to benzene, there was a significant risk of cancer affecting the blood cells and a 1.8-fold excess of lung cancer among them. This study will expand those findings and also identify the effects of benzene amounts and whether there is a genetic tendency for benzene poisoning. About 3,860 benzene-exposed workers from the 12 cities will be interviewed. Next-of-kin of deceased workers, and a subcohort (additional grouping) of participants will serve as a control group in the research. Patients who have worked at places where there was exposure to benzene will have a brief physical exam and samples of cells from a mouth rinse and samples from blood will be collected to study the genetic influence on developing blood diseases from workplace exposures. All participants or next-of-kin, for deceased, will be given a questionnaire about their work history, use of cigarettes and hair dyes, medications they take, and family history of cancer. Interviews of about 40 minutes long will be conducted at participants homes or workplaces, at a time convenient to them, and the interviews will be audiotaped.

Treatment options and clinical outcomes for acute myeloid leukemia (AML) have not improved for more than 40 years. AML patients are still suffering from receiving costly, ineffective chemotherapy treatments with very high chances of bad side effects. The purpose of this study is to take a look at leukemia cells to see if the investigators can learn what makes them up and makes them aggressive and hard to treat. We want to use this information to create new treatments that the investigators hope are more effective and less harmful for AML patients. Newly diagnosed, relapsed or refractory (post induction therapy) AML patients that are 18 years of age or older will have bone marrow and blood samples taken for their regular AML treatment. When these tests are done during their treatment the investigators will need to get some extra blood and bone marrow to do this research. The patients will not be asked to have an extra needle stick or bone marrow biopsy to get these samples. The patients will have the same number of blood and bone marrow tests whether they participate in this study or not. We will only need to get about two teaspoons of blood and two teaspoons of bone marrow each time the patient has these tests during their regular AML treatment. The research the investigators do with these sample will not decide or change the care the patients get for their AML.

This project aim at deciphering immune mechanisms that allow the immunoescape of AML initiating cells.

This study is to test a new therapy for patients with acute myeloid leukaemia who are undergoing blood stem cell transplant. In this study, the investigators will take a small number of your immune cells whose normal function is to give immunity to infections and help to fight leukaemia. These cells will be stimulated to multiply in the laboratory and will then be given to the transplant recipient after the transplant. This is a sort of "immunity transplant". The exact purpose of this study is to investigate if these cells are safe and effective in patients having a transplant for AML.

The goal of this clinical trial is to test passive music therapy in patients receiving induction chemotherapy for an acute myeloblastic leukemia or undergoing an hematopoietic stem cell transplantation. The main questions it aims to answer are: - Can music therapy control physical and psychological symptoms and improve the mood and quality of life of these patients? Participants will be randomly assigned to the control and experimental group. Patients included in both groups will complete weekly mood and quality of life questionnaires. Those included in the experimental group will also complete daily symptom burden questionnaires before and after listening to a music therapy session. Researchers will confirm if the experimental group improves their symptoms after the music therapy session and will compare both groups to see if there are differences in mood and quality of life.

Over recent decades, improvements have been made in the treatment of adult acute myeloid leukemia (AML). This has been mainly attributed to improvements in supportive therapy and to intensification of treatment strategies. The introduction of a post-induction myeloablative regimen followed by allogeneic stem cell transplant (SCT) has reduced the relapse rate in younger adults. However, this procedure is limited by the availability of human leukocyte antigen (HLA)-identical donors and conventional SCT preparative regimens according to patient age. In the absence of a compatible donor, myeloablative chemotherapy followed by autologous peripheral blood (PB) SCT remains one treatment strategy in adult patients with AML, allowing 35 - 50% long-term survivors. Despite several advantages of the CD34+ cell mobilization procedure, recent data have shown that relapse was higher and leukemia-free survival (LFS) shorter compared with bone marrow (BM) autografts. Higher doses of CD34+ peripheral blood stem cells (PBSCs) are collected to ensure engraftment and possibly reduce the incidence of treatment-related mortality (TRM). Although there is a threshold CD34+ cell dose below which engraftment is delayed in AML, the positive linear correlation of the number of CD34+ cells and kinetics of engraftment reaches a limit above which an increase in the number of progenitor cells does not provide any additional benefit. Relapse has been shown to be higher and survival shorter for those who receive the highest CD34+ PB doses. Although highly active against the leukemia bulk, intensive chemotherapy often spares the hardiest leukemia stem cells (LSCs) responsible for relapse. Detection of minimal residual disease (MRD) in autologous PBSC products may reflect inadequate in vivo purging, at least in part responsible for relapse. Although representing a heterogeneous cell population including both normal and leukemia cells, and despite that recent data have challenged the CD34+ CD38- phenotype of LSCs in AML, the CD34+ CD38- cell population generally remains considered enriched for LSCs. In this setting, MRD remaining during morphological complete remission (CR) should be relatively enriched in CD34+ CD38- leukemia cells, and their persistence after CR achievement should correlate with disease recurrence. This was investigated in a cohort of 123 patients with AML following apheresis procedures after CR achievement. The investigators also studied the impact of the infused dose of subpopulations of CD34+ PB cells on the outcome of a subset of 71 patients who further underwent autologous PBSCT.
