Filter by:RATIONALE: Drugs used in chemotherapy, such as melphalan, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Radiolabeled monoclonal antibodies can find cancer cells and carry cancer-killing substances to them without harming normal cells. A stem cell transplant using stem cells from the patient may be able to replace blood-forming cells that were destroyed by the chemotherapy and radiolabeled monoclonal antibody. PURPOSE: This randomized phase II trial is studying how well high-dose melphalan works when given with or without radiolabeled monoclonal antibody in treating patients with multiple myeloma undergoing an autologous stem cell transplant.
RATIONALE: Biological therapies, such as anti-thymocyte globulin, may stimulate the immune system in different ways and stop cancer cells from growing. Drugs used in chemotherapy, such as melphalan, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Anti-thymocyte globulin may also make cancer cells more sensitive to melphalan. Giving anti-thymocyte globulin together with melphalan may kill more cancer cells. PURPOSE: This phase II trial is studying how well giving anti-thymocyte globulin together with melphalan works in treating patients with relapsed multiple myeloma.
RATIONALE: Giving chemotherapy and total-body irradiation before a donor umbilical cord blood 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 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 tacrolimus and mycophenolate mofetil before and after transplant may stop this from happening. PURPOSE: To look at the ability of umbilical cord blood cells from one or two unrelated donors to serve as a source of stem cells for people needing a bone marrow transplant.
RATIONALE: Deferasirox may be effective in treating iron overload caused by blood transfusions in patients who have undergone donor stem cell transplant. PURPOSE: This phase II trial is studying the side effects and how well deferasirox works in treating patients with iron overload after donor stem cell transplant.
RATIONALE: Studying blood or mouthwash samples in the laboratory from patients receiving melphalan for cancer may help doctors learn more about changes that occur in DNA, identify biomarkers related to cancer, and help predict how patients will respond to treatment. PURPOSE: This clinical trial is studying common genetic mutations related to mucositis in patients with multiple myeloma receiving high-dose melphalan.
RATIONALE: Lenalidomide may stop the growth of multiple myeloma by blocking blood flow to the cancer. Monoclonal antibodies, such as rituximab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Giving lenalidomide together with rituximab may be an effective treatment for multiple myeloma. PURPOSE: This phase II trial is studying the side effects of giving lenalidomide together with rituximab and to see how well it works in treating patients with recurrent or refractory multiple myeloma.
RATIONALE: Interferon alfa may interfere with the growth of cancer cells. Interleukin-6 may stimulate the white blood cells to kill cancer cells. Giving interferon alfa together with interleukin-6 may kill more cancer cells. PURPOSE: This clinical trial is studying the side effects and how well giving interferon alfa together with interleukin-6 works in treating patients with recurrent multiple myeloma.
RATIONALE: Vaccines made from the patient's cancer cells may help the body build an effective immune response to kill cancer cells. Giving vaccine therapy together with donor lymphocyte infusion after a stem cell transplant from the patient's brother or sister may kill any cancer cells that remain after transplant. PURPOSE: This clinical trial is studying the side effects, best dose, and how well vaccine therapy with or without donor lymphocyte infusion works in treating patients with acute myeloid leukemia, acute lymphoblastic leukemia, or multiple myeloma undergoing donor stem cell transplant.
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.
RATIONALE: Giving CpG 7909 after an autologous stem cell transplant may make a stronger immune response and prevent or delay the recurrence of cancer. PURPOSE: This phase I trial is studying the side effects and best dose of CpG 7909 in treating patients who have undergone autologous stem cell transplant.
