Active clinical trials for "Lymphoproliferative Disorders"

This investigator initiated trial was a prospective, open, single-arm, diagnostic-prognostic study. Patients who received high-dose therapy with autologous stem cell transplantation for the treatment of their lymphoproliferative disease were included into the study. After completion of the high-dose therapy (day -2 with respect to the stem cell transplantation) the first blood sample A for the cytocapacity test with determination of leukocytes and neutrophils was taken in the evening of day -1. Directly thereafter the study medication was administered. The second blood sample B for the cytocapacity test with determination of leukocytes and neutrophils was taken in the morning of day 0, 12-14 hours after administration of the study medication. Thereafter the stem cell re-infusion was performed. The primary objective of this study was to show that the cytocapacity test with lenograstim is a useful predictive tool with respect to the risk of post-transplant complications and prolonged myelosuppression, typically occurring after high-dose chemotherapy. The primary variables were: the rate of patients with documented infections the time to platelet engraftment

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.

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.

Post-transplant lymphoproliferative disorders (PTLD) can present as a type of malignancy that limits patient and graft survival after solid organ transplantation. Many early PTLDs are driven by the Epstein-Barr Virus (EBV). Once acquired, EBV virus establishes latency in B-cells and can reactivate under immunosuppression. The highest risk transplant type to develop PTLD are lung transplants who have newly acquired EBV from their donors (D+/R-). There are no good modalities to prevent PTLD from developing after transplant. Rituximab is a monoclonal antibody that depletes B-cells thereby also reducing the burden of EBV. However, rituximab can have toxicities when given intravenously including infusion reactions and increased risk of reactions. Furthermore, more than one dose is usually required. The Toronto Transplant program has developed a technology called ex vivo lung perfusion that repairs lungs outside of the body. Preliminary work has shown that rituximab given through the EVLP circuit can coat B-cells. We have also shown that there is no toxicity to the lung by giving rituximab. The current highly novel study proposes to treat donor lungs ex-vivo with rituximab in order to decrease the amount of B-cells and EBV in the graft. These lungs will then be transplanted into EBV negative patients with the hope that transmission of EBV would be reduced or prevented. Ten patients will be included in the current trial. Outcomes include safety, EBV viral load, and B-cell measurements in biopsies.

RATIONALE: Collecting information about the effect of hematologic cancer and its treatment on quality of life may help doctors learn more about the disease and plan the best treatment. PURPOSE: This phase I trial is studying quality of life in younger leukemia and lymphoma survivors.

This study will evaluate the usefulness of FDG-PET scanning in distinguishing autoimmune lymphoproliferative syndrome (ALPS) from lymphoma. Lymphoma is cancer of the lymph system. ALPS is a condition involving persistent enlargement of the lymph glands, spleen, or liver, and a range of other problems relating to blood cell counts and abnormal immune activity, in which the immune system attacks healthy tissues. People with ALPS particularly those with an abnormal Fas gene also have an increased risk of developing lymphoma. The Fas gene codes for a protein that causes immune cells called lymphocytes to die when they are no longer needed. FDG-PET is a new nuclear imaging test that is very effective in detecting lymphoma. It is important to identify these cancers as quickly as possible, since some are very curable when caught early. Since ALPS and lymphoma share several common characteristics, a reliable, non-invasive method of distinguishing the two, such as FDG-PET might offer, is crucial. FDG-PET uses a radioactive sugar molecule to produce images that show the metabolic activity of tissues. Because cancer cells grow and divide more rapidly than normal cells, they metabolize more sugar for fuel. This increased activity identifies them as cancer in FDG-PET scanning. For this procedure, the subject is injected with the sugar molecule and lies in a doughnut-shaped machine (PET camera) for the imaging. Adults and children 10 years old or older with ALPS, with or without lymphoma, may be eligible for this study. Candidates will be screened with a physical examination, blood tests, and computed tomography (CT) scan. Participants will have an FDG-PET scan and a DEXA scan. The DEXA scan measures fat and non-fat tissue and is used help interpret the FDG-PET results. For this test, the subject lies on a table while a fast X-ray is taken from head to toe. Patients who develop signs or symptoms suggesting the development or recurrence of lymphoma (such as further enlargement of lymph glands, unexplained fever or weight loss, or abnormal scans) may undergo a tissue biopsy. For this procedure, a small piece of lymph or other tissue is surgically removed for examination under the microscope. In addition, patients who develop these symptoms may be asked to undergo additional FDG-PET scans up to two a year in patients without lymphoma, and as many as needed in patients with lymphoma to evaluate their response to treatment and guide future therapy.

The purpose of this study is to assess the seroconversion rate and the cellular immune response after vaccination against hepatitis B virus in patients with lymphoproliferative syndrome like chronic lymphocytic leukemia stade A and follicular lymphoma without of treatment criteria.

This retrospective study collects and evaluates the clinical experience reached in Italy on the use of bendamustine alone or combined with rituximab as treatment of patients with relapsed or refractory chronic lymphoproliferative disorders.

RATIONALE: Gathering information about how often methemoglobinemia occurs in young patients receiving dapsone for hematologic cancer or aplastic anemia may help doctors learn more about the disease and plan the best treatment. PURPOSE: This research study is looking at methemoglobinemia in young patients with hematologic cancer or aplastic anemia treated with dapsone.
