Active clinical trials for "Plasmacytoma"

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. Ultraviolet-B light therapy given before and after allogeneic stem cell transplantation may help prevent this from happening. PURPOSE: Clinical trial to study the effectiveness of combining ultraviolet-B light therapy with allogeneic stem cell transplantation in treating patients who have hematologic malignancies.

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. An autologous stem cell transplant using the patient's stem cells may be able to replace blood-forming cells that were destroyed by chemotherapy. Giving white blood cells from a donor may help the patient's body destroy any remaining cancer cells. Interleukin-2 may stimulate the white blood cells to kill cancer cells. PURPOSE: This phase I/II trial is studying the side effects of donor white blood cell infusions and interleukin-2 and to see how well they work in treating patients who are undergoing an autologous stem cell transplant for relapsed advanced lymphoid cancer.

RATIONALE: Giving low doses of chemotherapy, such as fludarabine and busulfan, before a donor peripheral blood 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 system and help destroy any remaining cancer cells (graft-versus-tumor effect). Giving an infusion of the donor's T cells (donor lymphocyte infusion) after the transplant may help increase this effect. Sometimes the transplanted cells from a donor can also 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/II trial is studying the side effects of giving busulfan and fludarabine together with total-body irradiation and to see how well they work in treating patients who are undergoing a donor stem cell transplant for hematologic cancer.

RATIONALE: Peripheral blood stem cell transplant using stem cells from the patient or a donor may be able to replace immune cells that were destroyed by chemotherapy used to kill tumor cells. The donated stem cells may also help destroy any remaining cancer cells (graft-versus-tumor effect). PURPOSE: This phase II trial is studying how well autologous peripheral stem cell transplant followed by donor peripheral stem cell transplant works in treating patients with multiple myeloma.

RATIONALE: Monoclonal antibodies such as daclizumab can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. Peripheral stem cell transplantation from a brother or sister may be effective treatment for hematologic cancer. Sometimes the transplanted cells can be rejected by the body's tissue. Mycophenolate mofetil, tacrolimus, and donor white blood cells may prevent this from happening. PURPOSE: Phase II trial to study the effectiveness of mycophenolate mofetil, tacrolimus, daclizumab, and donor peripheral stem cell transplantation in treating patients who have hematologic cancer.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase I trial to study the effectiveness of PS-341 in treating patients who have advanced cancer.

Randomized phase I trial to study the effectiveness of tipifarnib in treating patients who have advanced hematologic cancer. Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one chemotherapy drug may kill more cancer cells. PURPOSE: Phase II trial to study the effectiveness of phenylbutyrate plus azacitidine in treating patients who have acute myeloid leukemia, myelodysplasia, non-Hodgkin's lymphoma, multiple myeloma, non-small cell lung cancer, or prostate cancer.

RATIONALE: Bone marrow transplantation may be able to replace immune cells that were destroyed by chemotherapy and radiation therapy used to kill tumor cells. PURPOSE: Phase II trial to study the effectiveness of bone marrow transplantation in treating patients who have hematologic cancer.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Radioactive drugs such as holmium Ho 166 DOTMP can kill cancer cells without harming healthy cells. Peripheral stem cell transplantation may be able to replace immune cells that were destroyed by chemotherapy or radiation therapy used to kill tumor cells. PURPOSE: Randomized phase III trial to compare the effectiveness of melphalan with or without holmium Ho 166 DOTMP followed by peripheral stem cell transplantation in treating patients who have multiple myeloma.
