Filter by:This phase II trial is studying how well giving clofarabine and cytarabine together with filgrastim works in treating patients with newly diagnosed acute myeloid leukemia (AML), advanced myelodysplastic syndrome (MDS), and/or advanced myeloproliferative neoplasm. Drugs used in chemotherapy, such as clofarabine and cytarabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving the drugs in different doses may kill more cancer cells. Colony stimulating factors, such as filgrastim, may increase the number of immune cells found in bone marrow or peripheral blood and may help the immune system recover from the side effects of chemotherapy.
RATIONALE: Antimicrobial solution comprising trimethoprim-sulfamethoxazole, edetate calcium disodium, and ethanol may help prevent blockages and infections from forming in patients with central venous access catheters or peripheral venous catheters. PURPOSE: This randomized trial is studying an antimicrobial solution or saline solution in maintaining catheter patency and preventing catheter-related blood infections in patients with malignancies.
RATIONALE: Giving chemotherapy before a donor umbilical cord blood transplant (UCBT) helps stop the growth of cancer and abnormal cells and helps stop the patient's immune system from rejecting the donor's stem cells. When the stem cells from an unrelated donor, that do not exactly match the patient's blood, 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 antithymocyte globulin before transplant and cyclosporine and mycophenolate mofetil after transplant may stop this from happening. PURPOSE: This phase II trial is studying how well donor umbilical cord blood stem cell transplant works in treating patients with hematologic malignancies.
RATIONALE: Studying samples of semen from cancer survivors in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. PURPOSE: This phase I research study is looking at the presence of donor-derived DNA in semen samples form cancer survivors who underwent donor stem cell transplant.
RATIONALE: Giving chemotherapy and total-body irradiation (TBI) before a donor peripheral blood stem cell transplant helps stop the growth of cancer cells and helps stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells from a donor are infused into the patient they will help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Giving colony-stimulating factors, such as filgrastim (G-CSF) and plerixafor, to the donor helps the stem cells move (mobilization) from the bone marrow to the blood so they can be collected and stored. PURPOSE: This clinical trial is studying giving plerixafor and filgrastim together for mobilization of donor peripheral blood stem cells before a peripheral blood stem cell transplant in treating patients with hematologic malignancies
This phase II trial is studying the side effects and how well giving fludarabine phosphate, busulfan, anti-thymocyte globulin followed by donor peripheral blood stem cell transplant, tacrolimus, and methotrexate works in treating patients with myeloid malignancies. Giving chemotherapy, such as fludarabine phosphate and busulfan, before a donor peripheral blood stem cell transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's 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 anti-thymocyte globulin before transplant and tacrolimus and methotrexate after transplant may stop this from happening.
The present project aims at evaluating the capacity of MSC to improve one-year overall survival of patients transplanted with HLA-mismatched PBSC from related or unrelated donors after non-myeloablative conditioning. Co-infusion of MSC has been shown to facilitate engraftment of hematopoietic stem cell (HSC) in an immunodeficient mouse model. In addition, it has been shown that infusion of third party MSC in HSC transplantation could be successfully used as treatment for grade II-IV steroid-refractory acute graft versus host disease. One hundred and twenty patients with HLA-mismatched donors will be included over 6 years at multiple centers across Belgium through the transplant committee of the Belgian Hematological Society. The conditioning regimen will consist of fludarabine and 2 Gy TBI, followed by the infusion of donor HSC. Patients will be randomized 1/1 in double-blind fashion to receive or not MSC (1.5-.3.0 x106/kg) from third-party (either haploidentical family members or unrelated volunteer) donors on day 0. Postgrafting immunosuppression will combine tacrolimus and MMF. Except for the collection, expansion and infusion of MSC, the clinical management of the patient will not differ from that of routine NM-HCT.
RATIONALE: Studying samples of bone marrow and blood from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict how patients will respond to treatment. PURPOSE: This research study is looking at bone marrow and blood samples from patients with leukemia or other hematopoietic cancers.
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.
This phase I trial studies pretargeted radioimmunotherapy and donor peripheral blood stem cell transplant employing fludarabine phosphate and total-body irradiation (TBI) to treat patients with high-risk acute myeloid leukemia, acute lymphoblastic leukemia, or myelodysplastic syndrome. Giving chemotherapy drugs, such as fludarabine phosphate, and TBI before a donor peripheral blood stem cell transplant helps stop the patient's immune system from rejecting the donor's stem cells. Radiolabeled monoclonal antibodies can be combined with fludarabine phosphate and TBI to find cancer cells and kill them without harming normal cells. Pretargeted radioimmunotherapy (PRIT) allows for further improved targeting of tumor cells over standard directly labeled antibodies.
