Filter by:RATIONALE: Peripheral stem cell transplantation may be able to replace immune cells that were destroyed by chemotherapy. Sometimes the transplanted cells from a donor are rejected by the body's normal cells. Eliminating the T cells from the donor cells before transplanting them may prevent this from happening. Infusions of donor lymphocytes may decrease the body's rejection of the transplanted peripheral stem cells. PURPOSE: Phase II trial to study the effectiveness of allogeneic stem cell transplantation followed by donor lymphocyte infusions in treating patients who have hematologic cancer.
RATIONALE: Cyproheptadine and megestrol may improve appetite and help prevent weight loss in children with cancer. PURPOSE: This phase II trial is studying how well cyproheptadine and megestrol work in improving appetite and preventing weight loss in children with cachexia caused by cancer or cancer treatment.
RATIONALE: Antifungals such as ravuconazole may be effective in preventing fungal infections in patients undergoing chemotherapy and stem cell transplantation. PURPOSE: Phase I/II trial to study the effectiveness of ravuconazole in preventing fungal infections in patients undergoing allogeneic stem cell transplantation.
RATIONALE: Drugs used in chemotherapy such as cytarabine use different ways to stop cancer cells from dividing so they stop growing or die. 3-AP may stop the growth of cancer cells by blocking the enzymes necessary for cancer cell growth and may help cytarabine kill more cancer cells by making them more sensitive to the drug. PURPOSE: Phase I trial to study the effectiveness of combining cytarabine with 3-AP in treating patients who have relapsed or refractory hematologic cancer.
RATIONALE: Antibiotics such as amoxicillin, ciprofloxacin, and moxifloxacin may be effective in preventing or controlling fever and neutropenia in patients with cancer. It is not yet known whether moxifloxacin alone is more effective than amoxicillin combined with ciprofloxacin in treating neutropenia and fever. PURPOSE: This randomized clinical trial is studying how well moxifloxacin works and compares it to ciprofloxacin together with amoxicillin in treating neutropenia and fever in patients with cancer.
RATIONALE: Adjusting the dose of drugs used in chemotherapy such as cyclophosphamide may decrease side effects while stopping cancer cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage cancer cells. Stem cell transplantation may be able to replace immune cells that were destroyed by chemotherapy and radiation therapy used to kill cancer cells. PURPOSE: Phase I trial to study the effect on the body of dose-adjusted cyclophosphamide combined with total-body irradiation and donor stem cell transplantation in treating patients who have hematologic cancer.
Bone marrow transplantation (BMT) is a risky procedure. If doctors could reduce the complications, BMT would be safer to use for a wider range of conditions. The purposes of this study are - to prevent graft rejection by increasing the amount of immunosuppression and by giving some lymphocytes from the donor before transplant; - to prevent graft-versus-host disease (GVHD) by transplanting T-cell depleted stem cells; - to improve the immune effect against residual leukemia by the add-back of donor lymphocytes before transplant and six or more weeks after transplant. Beyond the standard transplant protocol, study participants will undergo additional procedures. First, along with total body irradiation, patients will receive two drugs (a high dose of cyclophosphamide and fludarabine) to suppress immunity and prevent rejection of the transplant. Second, four days before the transplant, patients will be given donor lymphocytes that have been irradiated to make them incapable of causing GVHD. On the day of the transplant, patients will receive an infusion of T-cell depleted bone marrow stem cells. Finally, patients will receive two doses of add-back donor T-cells (45 and 100 days post transplant) and the immunosuppressive drug cyclosporine starting on day 44 until about six months after transplant. Study participants must be between the ages of 10 and 56 and have a family member who is a suitable stem cell donor match.
RATIONALE: Umbilical cord blood transplantation may be able to replace immune cells that were destroyed by the chemotherapy or radiation therapy that was used to kill cancer cells. PURPOSE: Phase II trial to study the effectiveness of allogeneic umbilical cord blood transplantation in treating patients who have leukemia, lymphoma, or nonmalignant hematologic disorders.
RATIONALE: Combining antithymocyte globulin with combination chemotherapy before donor peripheral stem cell transplantation may reduce the chance of developing graft-versus-host disease following transplantation. PURPOSE: Phase I/II trial to study the effectiveness of combining antithymocyte globulin with busulfan and cyclophosphamide in reducing graft-versus-host disease in patients who are undergoing donor stem cell transplantation for myelodysplastic syndrome or other myeloproliferative disorder.
RATIONALE: Giving chemotherapy and total-body irradiation before a donor peripheral stem cell transplant 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 a related 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. PURPOSE: This phase II trial is studying how well giving chemotherapy with or without radiation therapy followed by donor stem cell transplant works in treating patients with hematologic cancer.
