Active clinical trials for "Preleukemia"

Recent investigations have demonstrated that DNMT gene polymorphisms can contribute to the inter-individual variants in DNMT expression. Accordingly, we hypothesized that the DNMT and HDAC genes SNPs could predict the outcomes of decitabine therapy for myelodysplastic syndrome. Prospective collection of DNA from peripheral blood will be performed in the patients with MDS before commencement of decitabine therapy. We will evaluate the efficacy decitabine therapy according to the DNMT or HDAC gene SNPs in terms of following parameters: 1) hematolotic response (HR) or improvement (HI), or requirement of decitabine dose to achieve HR or HI, 2) complete (CR) or partial response (PR), or requirement of decitabine dose to achieve CR or PR, and 3) time to relapse or progression of MDS. The objective of this study is 1) to determine genotypes from DNA samples from MDS patients receiving Decitabine therapy, 2) to determine the association of clinical outcomes (HR, HI, CR, PR or time to progression to leukemia) following decitabine therapy with DNMT or HDAC genotypes, and 3) to analyze the impact of cytogenetic risk on the response or leukemic evolution following decitabine therapy for MDS.

In Myelodysplastic syndrome, epigenetic treatments such as Azacitidine and Decitabine have been highlighted in phase 3 studies. However, as the 1st line treatment, it has not been evaluated the head to head comparison of two drugs. This study is a retrospective study to compare the efficacy of two drugs.

RATIONALE: Gathering information about how often methemoglobinemia occurs in young patients receiving dapsone for hematologic cancer or aplastic anemia may help doctors learn more about the disease and plan the best treatment. PURPOSE: This research study is looking at methemoglobinemia in young patients with hematologic cancer or aplastic anemia treated with dapsone.

RATIONALE: Collecting and storing samples of blood and bone marrow from patients with cancer to study in the laboratory may help doctors learn more about diagnosing cancer and how well patients will respond to treatment. PURPOSE: The purpose of this study is to collect and store blood and bone marrow samples from patients with hematologic cancer to be tested in the laboratory.

This is a dose and schedule finding study of AMG 531 designed to assess the activity of AMG 531 to reduce the rate of clinically significant bleeding and blood transfusions in subjects with myelodysplastic syndrome (MDS) receiving lenalidomide. Subjects with MDS that are planned to receive at least four cycles of lenalidomide for treatment of their disease are appropriate to screen for this study. All subjects meeting the eligibility criteria will receive lenalidomide 10 mg capsule by mouth daily every day of each 28-day cycle. Subjects will receive AMG 531 or placebo once a week by subcutaneous injection for 16 weeks.

RATIONALE: Questionnaires that measure quality-of-life may improve the health care team's ability to plan supportive care for patients undergoing donor bone marrow transplantation. PURPOSE: This clinical trial is studying quality of life in patients who are undergoing donor bone marrow transplantation.

RATIONALE: Studying quality of life in cancer survivors may help determine the long-term effects of hematologic cancer and may help improve the quality of life for future cancer survivors. PURPOSE: This clinical trial is studying the quality of life of adult cancer survivors who have undergone a previous bone marrow or peripheral stem cell transplant for a childhood hematologic cancer.

RATIONALE: Diagnostic procedures may improve the ability to detect residual disease. PURPOSE: Clinical trial to detect the presence of residual disease in children who are receiving therapy for acute myeloid leukemia or myelodysplastic syndrome.

Although PARP inhibitors (PARPi) have proved effective in treating many cancers, few patients receiving PARPi may experience rare but life-threatening adverse events such as myelodysplastic syndrome (MDS) and/or acute myeloid leukaemia (AML). Today, data about MDS/AML are scarce. The objective was to investigate reports of MDS/AML adverse events related to PARPi, including olaparib, rucaparib, niraparib, talazoparib and veliparib using the World Health Organization (WHO) and the French pharmacovigilance databases.

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.
