Active clinical trials for "Plasmacytoma"

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of combining O6-benzylguanine with carmustine in treating patients who have previously untreated, refractory, or relapsing multiple myeloma.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. White blood cells from donors may be able to prevent graft-versus-host disease in patients with hematologic cancer that has relapsed following donor peripheral stem cell transplantation. PURPOSE: Phase I trial to study the effectiveness of chemotherapy plus donor white blood cell infusion in treating patients who have relapsed hematologic cancer following donor peripheral stem cell transplantation.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Vitamin C may increase the effectiveness of arsenic trioxide by making cancer cells more sensitive to the drug. PURPOSE: Phase I/II trial to determine the effectiveness of arsenic trioxide plus vitamin C in treating patients who have recurrent or refractory multiple myeloma.

RATIONALE: Peripheral stem cell transplantation may be able to replace immune cells that were destroyed by chemotherapy or radiation therapy. PURPOSE: Randomized phase I/II trial to study the effectiveness of peripheral stem cell transplantation in treating patients who have breast cancer or hematologic cancer.

RATIONALE: Peripheral blood lymphocyte therapy may be effective in the treatment and prevention of Epstein-Barr virus infection following transplantation. PURPOSE: Phase II trial to study the effectiveness of peripheral blood lymphocyte therapy in treating and preventing lymphoproliferative disorders in patients who have Epstein-Barr virus infection following transplantation.

RATIONALE: Giving chemotherapy drugs and total-body irradiation before a donor bone marrow transplant helps stop the growth of cancer cells. It also 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. PURPOSE: This phase II trial is studying how well donor bone marrow transplant works in treating patients with hematologic cancers.

RATIONALE: Radiation therapy uses high-energy x-rays to damage cancer cells. Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining chemotherapy with bone marrow transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of bone marrow transplantation in treating patients who have hematologic cancer.

RATIONALE: Thalidomide may slow the growth of cancer cells. Oblimersen may increase the effectiveness of thalidomide and dexamethasone by making cancer cells more sensitive to the drugs. PURPOSE: Phase II trial to study the effectiveness of combining thalidomide and dexamethasone with oblimersen in treating patients who have relapsed or refractory multiple myeloma.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Peripheral stem cell transplantation may be able to replace immune cells that were destroyed by chemotherapy. Sometimes the transplanted cells are rejected by the body's tissues. Peripheral stem cell transplantation with the person's own stem cells followed by donor peripheral stem cell transplantation may prevent this from happening. PURPOSE: Phase II trial to study the effectiveness of combining chemotherapy with autologous peripheral stem cell transplantation and donor peripheral stem cell transplantation in treating patients who have multiple myeloma.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Deoxycytidine may protect patients from the side effects of high-dose cytarabine. PURPOSE: Phase I trial to study the effectiveness of high-dose cytarabine given with deoxycytidine in treating patients who have refractory acute myelogenous leukemia or other lymphoma or leukemia.
