Active clinical trials for "Plasmacytoma"

RATIONALE: Drugs used in chemotherapy, such as melphalan, use different ways to stop cancer cells from dividing so they stop growing or die. Stem cell transplant using stem cells from the patient may be able to replace immune cells that were destroyed by chemotherapy used to kill cancer cells. Giving colony-stimulating factors, such as G-CSF or pegfilgrastim, helps stem cells move from the bone marrow to the blood so they can be collected. It is not yet known which regimen is more effective in treating multiple myeloma. PURPOSE: This randomized phase II trial is studying how well high-dose chemotherapy followed by stem cell transplant works in treating patients with newly diagnosed stage I, stage II, or stage III multiple myeloma.

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. It is not yet known which combination chemotherapy regimen is most effective in treating older patients with multiple myeloma. PURPOSE: Randomized phase III trial to compare the effectiveness of combination chemotherapy with or without cyclophosphamide and prednisone in treating older patients with multiple myeloma.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one drug may kill more cancer cells. Steroids, such as dexamethasone or prednisolone, may help relieve some of the side effects of chemotherapy. It is not yet known which regimen of chemotherapy plus steroid therapy is more effective in treating patients with multiple myeloma. PURPOSE: Randomized phase III trial to compare the effectiveness of two different regimens of chemotherapy plus steroid therapy in treating patients with multiple myeloma that has recurred for the first time.

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 II trial to study the effectiveness of combination chemotherapy and peripheral stem cell transplantation in treating patients who have multiple myeloma.

RATIONALE: Giving chemotherapy drugs, such as fludarabine and melphalan, before a donor bone marrow transplant or peripheral blood stem cell transplant helps stop the patient's immune system from rejecting the donor's stem cells and helps stop the growth of cancer or abnormal 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 giving combination chemotherapy followed by donor bone marrow transplant or peripheral stem cell transplant works in treating patients with hematologic cancer or genetic disorders.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Enzyme products such as Wobe-Mugos E may help to reduce the side effects of multiple myeloma therapy. It is not yet known if chemotherapy is more effective with or without Wobe-Mugos E in treating multiple myeloma. PURPOSE: Randomized phase III trial to compare the effectiveness of chemotherapy with or without Wobe-Mugos E in treating patients who have stage II or stage III multiple myeloma.

RATIONALE: Antiemetic drugs, such as aprepitant and ondansetron, may help lessen nausea and vomiting caused by opioids. It is not yet known whether aprepitant is more effective than ondansetron in treating nausea and vomiting caused by opioids in patients with cancer. PURPOSE: This randomized clinical trial is studying aprepitant to see how well it works compared to ondansetron in treating nausea and vomiting caused by opioids in patients with cancer.

This pilot clinical trial studies mechanical stimulation in preventing bone density loss in patients undergoing donor stem cell transplant. Mechanical stimulation may limit, prevent, or reverse bone loss, increase muscle and cardiac performance, and improve overall health

RATIONALE: Antimicrobial solution comprising trimethoprim-sulfamethoxazole, edetate calcium disodium, and ethanol may help prevent blockages and infections from forming in patients with central venous access catheters or peripheral venous catheters. PURPOSE: This randomized trial is studying an antimicrobial solution or saline solution in maintaining catheter patency and preventing catheter-related blood infections in patients with malignancies.

RATIONALE: Studying samples of blood and bone marrow in the laboratory from patients with monoclonal gammopathy of undetermined significance, multiple myeloma, or plasmacytoma may help doctors learn more about changes that occur in DNA and identify biomarkers related to these diseases. It may also help doctors predict how patients will respond to treatment. PURPOSE: This research study is looking at blood and bone marrow samples from patients with monoclonal gammopathy of undetermined significance, multiple myeloma, or plasmacytoma.
