Active clinical trials for "Plasmacytoma"

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Bone marrow transplantation may be able to replace immune cells that were destroyed by chemotherapy or radiation therapy used to kill cancer cells. PURPOSE: Phase I trial to study the effectiveness of cyclophosphamide plus bone marrow transplantation in treating patients who have hematologic cancer.

RATIONALE: PS-341 may stop the growth of tumor cells by blocking the enzymes necessary for tumor cell growth. PURPOSE: Phase I trial to study the effectiveness of PS-341 in treating patients who have hematologic cancer.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Thalidomide may stop the growth of cancer by stopping blood flow to the tumor. Combining dexamethasone and thalidomide may kill more cancer cells. It is not yet known whether dexamethasone is more effective with or without thalidomide in treating multiple myeloma. PURPOSE: Randomized phase III trial to determine the effectiveness of dexamethasone with or without thalidomide 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. Holmium Ho 166 DOTMP may deliver radiation directly to cancer cells and cause less damage to normal tissue. Combining chemotherapy and holmium Ho 166 DOTMP with peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy and holmium Ho 166 DOTMP and kill more tumor cells. PURPOSE: Phase I/II trial to study the effectiveness of combining holmium Ho 166 DOTMP with melphalan and peripheral stem cell transplantation in treating patients who have multiple myeloma.

RATIONALE: Vorinostat may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Lenalidomide may stop the growth of multiple myeloma by blocking blood flow to the cancer. Giving vorinostat together with lenalidomide may kill more cancer cells. PURPOSE: This phase I trial is studying the side effects and best dose of vorinostat when given together with lenalidomide after autologous stem cell transplant in treating patients with multiple myeloma.

RATIONALE: Giving high-dose chemotherapy before an autologous stem cell transplant stops the growth of cancer cells by stopping them from dividing or killing them. An autologous stem cell transplant may be able to replace the blood-forming cells that were destroyed by the chemotherapy. PURPOSE: This phase II trial is studying how well giving busulfan together with cyclophosphamide followed by an autologous stem cell transplant works in treating patients with multiple myeloma.

RATIONALE: Biological therapies, such as lenalidomide, may stimulate the immune system in different ways and stop plasma cells from growing. Drugs used in chemotherapy, such as cyclophosphamide and dexamethasone, work in different ways to stop the growth of plasma cells, either by killing the cells or by stopping them from dividing. Giving lenalidomide together with cyclophosphamide and dexamethasone may be an effective treatment for primary systemic amyloidosis. PURPOSE: This phase II trial is studying how well giving lenalidomide together with cyclophosphamide and dexamethasone works in treating patients with primary systemic amyloidosis.

RATIONALE: Giving chemotherapy, such as cyclophosphamide and busulfan, and 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 from bone marrow or umbilical cord blood 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 methotrexate and cyclosporine after transplant may stop this from happening. PURPOSE: This phase II trial is studying how well a donor stem cell transplant works in treating patients with previously treated lymphoma, multiple myeloma, or chronic lymphocytic leukemia.

RATIONALE: Bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as doxorubicin and dexamethasone, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) together with bortezomib may kill more cancer cells. PURPOSE: This phase II trial is studying how well giving bortezomib together with doxorubicin and dexamethasone works in treating patients with multiple myeloma that has relapsed or not responded to treatment. PATIENT POPULATION: Patients with relapsed or refractory multiple myeloma requiring therapy will be invited to participate in this study. Eligible patients will be >18 years old and able to give fully informed consent. Patients must have a Performance Score (PS) of 0-3 (ECOG), measurable serum and/or urine paraprotein, or serum free light chain, bilirubin value of less than one and a half times the upper limit of normal with ALT/AST values less than two and a half times the upper limit of normal. Patients with non-secretory multiple myeloma are excluded from this study.

RATIONALE: Bortezomib and thalidomide may stop the growth of multiple myeloma by blocking blood flow to the cancer. Bortezomib may also stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving bortezomib together with thalidomide and dexamethasone may kill any cancer cells that remain after high-dose melphalan and stem cell transplant in patients with multiple myeloma. PURPOSE: This phase II trial is studying the side effects of giving bortezomib together with thalidomide and dexamethasone after melphalan and stem cell transplant and to see how well it works in treating patients with stage I-III multiple myeloma.
