View clinical trials related to Burkitt Lymphoma.
Filter by:Burkitt lymphoma (BL) is an aggressive monoclonal B-cell malignancy that is rare (sporadic) worldwide, but is 100-fold more common (endemic) in equatorial Africa, particularly among children. Epstein-Barr virus (EBV) and malaria are epidemiologically linked to endemic BL in epidemiologic studies, but questions remain about role of EBV variants and the evidence for association with malaria is weak. EBV is ubiquitous, yet only few children develop BL, possibly because only a few EBV variants are pathogenically relevant. The association of BL with malaria is based on ecologic and non-comparative clinical studies. Two case-control studies have reported significant association of high anti-malarial antibodies with BL (OR=5_ among children in Uganda and in Malawi, but selection bias (cases and controls came from dissimilar geographical areas) and reverse causality bias were limitations. Three studies were conducted in the 1960s and 70s to test association of carriage of malaria-resistance gene with BL, two of which reported a significant or marginal inverse association. These pioneering studies were small (240 cases all together) and looked at one polymorphism in one gene (sickle cell gene). Improvements in technologies to characterize genetic variation allow the EBV and malaria hypotheses to be examined with greater power by looking at genetic variation across multiple genes. Epidemiology of Burkitt lymphoma in East African children and minors (EMBLEM) is a case-control study of 1500 BL cases and 3000 age-, sex- and residence-frequency matched controls we are proposing to conduct in East Africa. The study will enroll cases at four hospitals in four regions in East Africa, where malaria transmission is holoendemic and year round. The controls will be enrolled from general population attendees at Health Center II (HC-II) units where the cases originated. The primary study objectives are: 1) to test the hypothesis that genetic resistance to malaria is associated with a lower risk of BL, and 2) to use genome-wide association methods to discover genetic variation that may be associated with decreased or increased risk of BL. Because genetic variation conveys no information on actual exposure to malaria or EBV, in secondary analyses, we will use empiric epidemiological questionnaire and laboratory methods: a) to measure exposure to malaria and its association with BL, and b) to measure EBV variants and their association with BL. To examine issues related to bias and to obtain data to correct for deviations, we will also enroll 2250 population controls from 5% of the villages to obtain population distribution of key exposures variables. This data will be used to reweight the distribution in HC-II controls back to the general population. ...
This is a pilot study, assessing the feasibility, safety and toxicity of an mTOR (mammalian target of Rapamycin) inhibitor (MTI), rapamycin, when administered with HyperCVAD (Hyperfractionated Cyclophosphamide, Vincristine, Doxorubicine and Dexamethasone), with an ultimate goal to perform a phase II study to evaluate response rates and survival in adults with Acute Lymphoblastic Leukemia (ALL) and aggressive lymphoid malignancies.
RATIONALE: Giving high doses of chemotherapy drugs, such as busulfan and cyclophosphamide, before a donor bone marrow transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's stem 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. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving cyclosporine, methylprednisolone, and methotrexate after transplant may stop this from happening. PURPOSE: This clinical trial studies high-dose busulfan and high-dose cyclophosphamide followed by donor bone marrow transplant in treating patients with leukemia, myelodysplastic syndrome, multiple myeloma, or recurrent Hodgkin or Non-Hodgkin lymphoma.
This phase I clinical trial is studying the side effects and best dose of RO4929097 when given together with capecitabine in treating patients with refractory solid tumors. RO4929097 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving RO4929097 together with chemotherapy may kill more tumor cells.
RATIONALE: AR-42 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. PURPOSE: This phase I trial is studying the side effects and best dose of AR-42 in treating patients with advanced or relapsed multiple myeloma, chronic lymphocytic leukemia, or lymphoma.
This phase II trial is studying how well giving bendamustine hydrochloride, etoposide, dexamethasone, and filgrastim together for peripheral stem cell mobilization works in treating patients with refractory or recurrent lymphoma or multiple myeloma. Giving chemotherapy, such as bendamustine hydrochloride, etoposide, and dexamethasone, before a peripheral stem cell transplant stops the growth of cancer cells by stopping them from dividing or killing them. Giving colony-stimulating factors, such as filgrastim, and certain chemotherapy drugs helps stem cells move from the bone marrow to the blood so they can be collected and stored
The purpose of this study is to determine the long-term safety of a fixed-dose, daily regimen of PCI-32765 PO in subjects with B cell lymphoma or chronic lymphocytic leukemia/small lymphocytic leukemia (CLL/SLL).
RATIONALE: Giving chemotherapy before a donor umbilical cord blood transplant (UCBT) helps stop the growth of cancer and abnormal cells and helps stop the patient's immune system from rejecting the donor's stem cells. When the stem cells from an unrelated donor, that do not exactly match the patient's blood, are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving antithymocyte globulin before transplant and cyclosporine and mycophenolate mofetil after transplant may stop this from happening. PURPOSE: This phase II trial is studying how well donor umbilical cord blood stem cell transplant works in treating patients with hematologic malignancies.
Background: - Burkitt lymphoma/leukemia (BL) is highly treatable, but most of the standard therapies require multiple doses of intensive chemotherapy that may require long hospital stays and frequently have severe side effects. In addition, BL is a fairly common type of cancer in patients who also have human immunodeficiency virus (HIV), but treatment outcomes are poor because standard treatments do not work very well in HIV-positive patients and the more intense treatment regimens are highly toxic. New approaches are needed that expand the ways to treat BL with the same efficiency but with reduced side effects. - Etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin, and rituximab (DA-EPOCH-R) is a standard chemotherapy treatment that consists of the drugs etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin, and rituximab. It may be able to treat BL with similar effectiveness but with fewer side effects. Researchers are interested in confirming the results of previous studies that investigated the effectiveness of DA-EPOCH-R in treating BL. Objectives: - To determine the safety and effectiveness of DA-EPOCH-R in treating Burkitt lymphoma. Eligibility: - Individuals at least 18 years of age who have been diagnosed with Burkitt lymphoma and have not had any prior chemotherapy treatments. Design: - Individuals will have a series of blood and other tests to determine their suitability for participating in the study. Eligible participants will be divided into high-risk and low-risk groups based on their disease prognosis and the possibility that the BL may or already has spread into the central nervous system. - Participants will receive intravenous infusion of the six chemotherapy drugs in DA-EPOCH-R in 21-day treatment cycles. The exact doses will be adjusted depending on participants white blood cell counts and other tests. - High-risk participants will receive six cycles of DA-EPOCH-R. To treat BL that may have entered the central nervous system, high-risk participants will also receive infusions of other chemotherapy drugs into their spinal fluid. - Low-risk participants will receive up to six cycles of DA-EPOCH-R, with an additional dose of rituximab during each cycle. - Frequent blood and urine tests will be performed during treatment, as well as body imaging scans and other tests of cancer progression as directed by the study doctors. Participants will receive additional medicines to help prevent possible adverse side effects of DA-EPOCH-R. - Participants who respond successfully to the treatment will be asked to return for follow-up exams every 3 months for the first 18 months, then every year for the next 3 years. Participants who do not respond successfully to the treatment will be given the opportunity to participate in additional research and treatment protocols, if any are available.
RATIONALE: Everolimus may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Lenalidomide may stop the growth of cancer cells by blocking blood flow to the cancer. Giving everolimus together with lenalidomide may be an effective treatment for lymphoma. PURPOSE: This phase I/II trial is studying the side effects and best dose of giving everolimus and lenalidomide together and to see how well they work in treating patients with relapsed or refractory non-Hodgkin or Hodgkin lymphoma.
