Active clinical trials for "Plasmacytoma"

RATIONALE: Drugs such as melphalan, thalidomide, and dexamethasone may be effective in treating patients with primary systemic amyloidosis. PURPOSE: This phase II trial is studying how well giving melphalan together with thalidomide and dexamethasone works in treating patients with primary systemic amyloidosis.

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 use different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Combining peripheral stem cell transplantation with chemotherapy and radiation therapy may allow the doctor to give higher doses of radiation and chemotherapy drugs and kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of high-dose melphalan plus total-body irradiation and peripheral stem cell transplantation in treating patients with multiple myeloma in first relapse.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. Interferon alfa may interfere with the growth of cancer cells. PURPOSE: Phase II trial to determine the effectiveness of giving interferon alfa after chemotherapy and peripheral stem cell transplantation to patients who have stage III or stage IV multiple myeloma and who have been treated with high-dose melphalan.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. PURPOSE: Phase I trial to study the effectiveness of MS-275 in treating patients who have 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.

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.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase II trial to study the effectiveness of tocladesine in treating patients who have recurrent or refractory multiple myeloma.
