Active clinical trials for "Plasmacytoma"

Patients with stage-I multiple myeloma are treated with a vaccine made from their own immune cells (dendritic cells) and their own myeloma protein. Vaccinations are given on 5 occasions every 4 weeks. The aim is to induce an immune reaction against the malignant myeloma cells in order to slow down or cure the disease.

RATIONALE: Probiotics, such as Lactobacillus, may be effective in preventing infections in patients with suppressed immune systems. PURPOSE: This phase I trial is studying the side effects and how well giving enteral nutrition, including Lactobacillus, works in preventing infections in patients undergoing donor stem cell transplant for hematologic cancer or myelodysplastic syndrome.

RATIONALE: A donor stem cell transplant can lower the body's immune system, making it difficult to fight off infection. Giving antibiotics, such as moxifloxacin, may help prevent bacterial infections in patients who have recently undergone donor stem cell transplant. It is not yet known whether moxifloxacin is more effective than a placebo in preventing bacterial infections in patients who have recently undergone donor stem cell transplant. PURPOSE: This randomized phase III trial is studying moxifloxacin to see how well it works compared with a placebo in preventing bacterial infections in patients who have recently undergone donor stem cell transplant.

RATIONALE: Antibiotics such as amoxicillin, ciprofloxacin, and moxifloxacin may be effective in preventing or controlling fever and neutropenia in patients with cancer. It is not yet known whether moxifloxacin alone is more effective than amoxicillin combined with ciprofloxacin in treating neutropenia and fever. PURPOSE: This randomized clinical trial is studying how well moxifloxacin works and compares it to ciprofloxacin together with amoxicillin in treating neutropenia and fever in patients with cancer.

RATIONALE: Diagnostic procedures, such as magnetic resonance imaging (MRI) and fludeoxyglucose F 18 positron emission tomography (^18FDG-PET) may help diagnose solitary plasmacytoma. PURPOSE: This clinical trial is studying MRI and ^18FDG-PET to see how well they work in diagnosing patients with solitary plasmacytoma.

This Phase II clinical trial was designed for patients with hematologic malignancies in need of donor peripheral blood stem cell transplant, and have no HLA matched donor. Therefore It will test the efficacy of combining sirolimus, tacrolimus, antithymocyte globulin, and rituximab in preventing graft versus host disease in transplants from HLA Haploidentical and partially mismatched donors.

RATIONALE: Methadone, morphine, or oxycodone may help relieve pain caused by cancer. It is not yet known whether methadone is more effective than morphine or oxycodone in treating pain in patients with cancer. PURPOSE: This randomized clinical trial is studying methadone to see how well it works compared with morphine or oxycodone in treating pain in patients with cancer.

RATIONALE: The influenza vaccine may help prevent flu in patients who have undergone stem cell transplant. PURPOSE: This clinical trial is studying how well the influenza vaccine works in preventing flu in patients who have undergone stem cell transplant and in healthy volunteers.

RATIONALE: Deferasirox may be effective in treating iron overload caused by blood transfusions in patients who have undergone donor stem cell transplant. PURPOSE: This phase II trial is studying the side effects and how well deferasirox works in treating patients with iron overload after donor stem cell transplant.

RATIONALE: Monoclonal antibodies such as rituximab can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. Biological therapies such as interferon alfa-2b use different ways to stimulate the immune system and stop cancer cells from growing. PURPOSE: Phase II trial to study the effectiveness of rituximab or interferon alfa-2b in treating patients who have chronic lymphocytic leukemia or multiple myeloma in remission.
