Bone Marrow Transplantation in Treating Patients With Severe Aplastic Anemia or Rejection of Previous...

Chronic Myeloproliferative DisordersGraft Versus Host Disease4 more

RATIONALE: Bone marrow from donors may be able to treat patients with severe aplastic anemia and patients whose bodies have rejected previous bone marrow transplantation. PURPOSE: Phase II trial to study the effectiveness of bone marrow transplantation in treating patients who have severe aplastic anemia or whose bodies have rejected previous bone marrow transplant.

Partially HLA-Matched Irradiated Allogeneic Cellular Therapy After Reduced Intensity Total Body...

LeukemiaLymphoma2 more

RATIONALE: Giving low-dose total-body irradiation before a donor stem cell transplant helps stop the growth of cancer 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 cells (graft-versus-tumor effect). PURPOSE: This phase I trial is studying the side effects of donor stem cell transplant after total-body irradiation and to see how well it works in treating patients with relapsed or refractory hematologic cancer or acute myeloid leukemia or acute lymphocytic leukemia in complete remission.

Donor T Cells in Treating Patients With High-Risk Hematologic Cancer Undergoing Donor Peripheral...

Graft Versus Host DiseaseLeukemia3 more

RATIONALE: A donor peripheral stem cell transplant helps stop the growth of cancer 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. Once the donated stem cells begin working, the patient's immune system may see the remaining cancer cells as not belonging in the patient's body and destroy them. Giving an infusion of donor T cells may helps stop the patient's immune system from rejecting the donor's stem cells. PURPOSE: This phase I/II trial is studying the side effects and best dose of donor T cells in treating patients with high-risk hematologic cancer who are undergoing donor peripheral blood stem cell transplant. Note: Only Phase I portion of study was performed. Due to slow accrual, study was closed before Phase II portion of study.

Anti-thymocyte Globulin and Melphalan in Treating Patients With Relapsed Multiple Myeloma

Multiple Myeloma and Plasma Cell Neoplasm

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.

High-Dose Melphalan With or Without Radiolabeled Monoclonal Antibody in Treating Patients With Multiple...

Multiple Myeloma and Plasma Cell Neoplasm

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.

Umbilical Cord Blood (UCB) Transplant, Fludarabine, Melphalan, and Anti-thymocyte Globulin (ATG)...

Myeloproliferative DisordersLeukemia3 more

RATIONALE: Giving low doses of chemotherapy before a donor umbilical cord blood transplant helps stop the growth of cancer cells. It may also 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 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 after the transplant may stop this from happening. PURPOSE: This phase II trial is studying how well giving umbilical cord blood transplant together with fludarabine, melphalan, and antithymocyte globulin works in treating patients with hematologic cancer.

T-Cell Depletion, Donor Hematopoietic Stem Cell Transplant (HSCT), and T-Cell Infusions in Treating...

Chronic Myeloproliferative DisordersLeukemia5 more

RATIONALE: Giving chemotherapy and total-body irradiation before a donor peripheral blood 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 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. Removing the T cells from the donor cells before transplant may stop this from happening. Giving an infusion of the donor's T cells (donor lymphocyte infusion) after the transplant may help destroy any remaining cancer cells (graft-versus-tumor effect). PURPOSE: This phase II trial is studying T-cell depletion in donor stem cell transplant followed by delayed T cell infusions in treating patients with hematologic cancer or other disease.

Vaccine Therapy With or Without Donor Lymphocyte Infusion in Treating Patients With Acute Myeloid...

LeukemiaMultiple Myeloma and Plasma Cell Neoplasm

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.

Chronic Myeloproliferative DisordersLeukemia5 more

RATIONALE: A peripheral stem cell transplant or an umbilical cord blood transplant from a donor may be able to replace blood-forming cells that were destroyed by chemotherapy or radiation therapy. Giving an infusion of the donor's white blood cells (donor lymphocyte infusion) after the transplant may help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells can make an immune response against the body's normal cells. Methotrexate, cyclosporine, tacrolimus, or methylprednisolone may stop this from happening. PURPOSE: This clinical trial is studying how well a donor stem cell transplant or donor white blood cell infusions work in treating patients with hematologic cancer.

CpG 7909 in Treating Patients Who Have Undergone Autologous Stem Cell Transplant

Germ Cell TumorLeukemia2 more

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.
