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 chemotherapy with peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. PURPOSE: Phase I/II trial to study the effectiveness of combining docetaxel, ifosfamide, and carboplatin followed by peripheral stem cell transplantation in treating patients with refractory cancer.

RATIONALE: 4'-Iodo-4'-deoxydoxorubicin may improve organ dysfunction and ease symptoms caused by primary systemic amyloidosis. PURPOSE: Phase II trial to study the effectiveness of 4'-iodo-4'-deoxydoxorubicin in treating patients who have primary systemic amyloidosis.

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 I trial to study the effectiveness of combining topotecan, fluorouracil, and leucovorin 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. Combining chemotherapy with bone marrow or peripheral stem cell 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 combination chemotherapy followed by bone marrow or peripheral stem cell transplantation in treating patients with multiple myeloma.

RATIONALE: Interleukin-12 may kill tumor cells by stopping blood flow to the tumor and by stimulating a person's blood cells to kill multiple myeloma cells. PURPOSE: Randomized phase II trial to compare the effectiveness of interleukin-12 given at different times in treating patients with multiple myeloma.

RATIONALE: Giving low doses of chemotherapy, such as fludarabine and busulfan, before a donor bone marrow or 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 immunosuppressive therapy after the transplant may stop this from happening. PURPOSE: This phase II trial is studying how well donor bone marrow or peripheral stem cell transplant works in treating patients with relapsed hematologic cancer after treatment with chemotherapy and autologous stem cell transplant.

RATIONALE: Giving chemotherapy before a donor bone marrow 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 cyclophosphamide, mycophenolate mofetil, or tacrolimus after transplant may stop this from happening. PURPOSE: This clinical trial is studying how well giving combination chemotherapy together with tacrolimus and mycophenolate mofetil works in treating patients who are undergoing a donor bone marrow transplant for hematologic cancer.

RATIONALE: Giving low doses of chemotherapy, such as melphalan and fludarabine, and a monoclonal antibody, such as alemtuzumab, before a donor bone marrow or 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). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving cyclosporine after the transplant may stop this from happening. PURPOSE: This phase II trial is studying how well fludarabine, melphalan, alemtuzumab, and peripheral stem cell transplant work in treating patients with hematologic cancer.

RATIONALE: Vaccines made from a person's tumor cells may make the body build an immune response and kill their tumor cells. Peripheral stem cell transplantation may be able to replace immune cells that were destroyed by chemotherapy used to kill tumor cells. PURPOSE: Phase II trial to study the effectiveness of peripheral stem cell transplantation plus vaccine therapy and chemotherapy in treating patients who have multiple myeloma.

RATIONALE: Peripheral stem cell transplantation may be able to replace immune cells that were destroyed by chemotherapy and radiation therapy used to kill tumor cells. PURPOSE: Phase I trial to study the effectiveness of treated donor stem cell transplantation in treating patients who have hematologic cancer.
