Filter by:RATIONALE: Giving chemotherapy before a donor peripheral stem cell transplant or bone marrow transplant using stem cells from a brother or sister that closely match the patient's stem cells, helps stop the growth of cancer or abnormal cells. It also helps stop the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer or abnormal cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving colony-stimulating factors, such as G-CSF, to the donor helps the stem cells move from the bone marrow to the blood so they can be collected and stored. Giving methotrexate and cyclosporine before and after transplant may stop this from happening. It is not yet known whether a donor peripheral stem cell transplant is more effective than a donor bone marrow transplant in treating hematologic cancers or other diseases. PURPOSE: This randomized phase III trial is studying filgrastim-mobilized sibling donor peripheral stem cell transplant to see how well it works compared with sibling donor bone marrow transplant in treating patients with hematologic cancers or other diseases.
RATIONALE: Pemetrexed disodium may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Studying samples of cerebrospinal fluid and blood from patients with cancer in the laboratory may help doctors learn how pemetrexed disodium works in the body and identify biomarkers related to cancer. PURPOSE: This clinical trial is studying the side effects and how well pemetrexed disodium works in treating patients with leptomeningeal metastases.
RATIONALE: Giving low doses of chemotherapy and total-body irradiation before a donor umbilical cord blood stem cell transplant helps stop the growth of cancer or abnormal cells. It also stops the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer or abnormal cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving tacrolimus and mycophenolate mofetil before the transplant may stop this from happening. PURPOSE: This clinical trial is studying how well umbilical cord blood stem cell transplant works in treating patients with hematologic cancer or other disease.
RATIONALE: Drugs used in chemotherapy, such as azacitidine, work in different ways to stop the growth of abnormal cells, either by killing the cells or by stopping them from dividing. PURPOSE: This phase II trial is studying how well azacitidine works in treating patients with myelofibrosis.
RATIONALE: Giving chemotherapy, such as fludarabine and cyclophosphamide, and total-body irradiation before a donor umbilical cord blood stem cell transplant helps stop the growth of cancer or abnormal 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. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer or abnormal cells (graft-versus-tumor effect). Giving an infusion of the donor's T-regulatory cells before the transplant may help increase this effect. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving cyclosporine and mycophenolate mofetil after the transplant may stop this from happening. PURPOSE: This phase I trial is studying the side effects and best dose of umbilical cord blood T-regulatory cell infusion followed by donor umbilical cord blood transplant in treating patients with high-risk leukemia or other hematologic diseases.
This phase II trial studies the side effects and how well decitabine works in treating patients with myelofibrosis, a cancer of the blood system associated with fibrosis (scar tissue) in the bone marrow that is advanced and for which there is no standard therapy. Decitabine may block the actions of some proteins that are responsible for turning certain genes off in various cancers including myelofibrosis.
