Active clinical trials for "Plasmacytoma"

RATIONALE: Biological therapies, such as lenalidomide, may stimulate the immune system in different ways and stop cancer cells from growing. Vaccines may help the body build an effective immune response to kill cancer cells. Giving lenalidomide together with vaccine therapy may make a stronger immune response and kill more cancer cells. PURPOSE: This phase II trial is studying how well giving lenalidomide together with vaccine therapy works in treating patients with relapsed or refractory multiple myeloma.

RATIONALE: Drugs used in chemotherapy, such as hydroxychloroquine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving hydroxychloroquine together with bortezomib may kill more cancer cells. PURPOSE: This phase I/II trial is studying the side effects and best dose of hydroxychloroquine when given together with bortezomib and to see how well it works in treating patients with relapsed or refractory multiple myeloma.

This is a Phase I/II, open-label, multi-center study conducted in patients with recurrent or refractory multiple myeloma who have failed at least two prior standard systemic treatments.

RATIONALE: Dexamethasone is used to treat multiple myeloma. Drugs used in chemotherapy may stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Plasma exchange is a process in which certain cells are separated from the plasma in the blood by a machine and then only the cells are returned to the patient. Dexamethasone and plasma exchange may be an effective treatment for acute kidney failure caused by multiple myeloma. It is not yet known whether giving dexamethasone and chemotherapy together with plasma exchange is more effective than giving dexamethasone and chemotherapy alone in treating patients with multiple myeloma and acute kidney failure. PURPOSE: This randomized phase III trial is studying dexamethasone, chemotherapy, and plasma exchange to see how well they work compared with dexamethasone and chemotherapy alone in treating patients with newly diagnosed multiple myeloma and acute kidney failure.

RATIONALE: Radioactive drugs, such as samarium Sm 153 lexidronam pentasodium, may carry radiation directly to cancer cells and not harm normal cells. Bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the cancer. Bortezomib may also make cancer cells more sensitive to radiation therapy. Giving samarium Sm 153 lexidronam pentasodium together with bortezomib may kill more cancer cells. PURPOSE: This phase I/II trial is studying the side effects and best dose of bortezomib when given together with samarium Sm 153 lexidronam pentasodium and to see how well they work in treating patients with relapsed or refractory multiple myeloma.

RATIONALE: Radioactive substances, such as samarium 153, may release radiation as it breaks down and kill cancer cells. Bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Bortezomib may also make tumor cells more sensitive to radiation. Giving samarium 153 together with bortezomib may kill more cancer cells. PURPOSE: This phase I trial is studying the side effects and best dose of samarium 153 when given together with bortezomib in treating patients with relapsed or refractory multiple myeloma.

RATIONALE: Lenalidomide may stop the growth of multiple myeloma by blocking blood flow to the cancer. It may also stimulate the immune system in different ways and stop cancer cells from growing. 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. Giving lenalidomide together with melphalan may kill more cancer cells. PURPOSE: This randomized phase II trial is studying the side effects and best dose of lenalidomide when given together with melphalan and to see how well they work in treating patients with multiple myeloma.

RATIONALE: Biological therapies, such as antithymocyte globulin, may stimulate the immune system in different ways and stop cancer cells from growing. PURPOSE: This phase II trial is studying how well antithymocyte globulin works in treating patients undergoing stem cell transplant for multiple myeloma.

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 donor 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 combining total-body irradiation with fludarabine and donor peripheral stem cell transplantation in treating patients who have hematologic cancer.

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.
