Filter by:The purpose of this study is to compare capillary blood count parameters with the corresponding venous samples to verify the hypothesis that capillary and venous blood count parameters are equivalent.
The purpose of this study is to identify and characterize blood diseases presenting at Shanghai hospitals and to compare them with respect to clinical presentation, phenotype, molecular characteristics, benzene or other exposures and genetic susceptibility.
The purpose of this study is to investigate the health effects of benzene exposure in workers in Shanghai, China.
GVHD prophylaxis of sirolimus and mycophenolate mofetil for patients undergoing matched related allogeneic transplant for acute and chronic leukemia, MDS, high risk NHL and HL
Leukemia holds a special place in the study of radiation-related cancer because bone marrow is one of the tissues most sensitive to the carcinogenic effect of ionizing radiation, radiogenic leukemia has the shortest latent period among radiation-induced cancers, and its appearance suggests that solid tumors may follow. These same characteristics also contribute to its considerable significance in radiation protection. There are, nevertheless, important gaps in existing knowledge of radiation-induced leukemia, gaps that derive from characteristics of the study of the atomic bombing of Hiroshima and Nagasaki, and from studies of the effects of medical irradiation and studies of nuclear workers, these being the studies that have provided most of the information to date. These gaps include the presumed reduction in risk resulting from dose-fractionation and low dose-rate, and the time-response function in the first five years after exposure. The primary objective of this study is to investigate leukemia risk as a function of such radiation; it would constitute the largest epidemiologic study conducted to date among working-age males, a group of particular concern in establishing occupational radiation safety standards. In addition, data on cases of multiple myeloma and myelodysplasia identified in the cohort will be collected to test the hypothesis of a dose related association between radiation and increased risk for each of these diseases. The primary scientific objectives of the proposed study are to test the following hypotheses: (a) that there is a dose-related increase in risk of leukemia among these liquidators; (b) that the magnitude of any observed risk per unit dose is less than that seen in the atomic bomb survivors, exposed to essentially instantaneous radiation. Subsidiary objectives include: (a) to investigate the nature of the dose-response relationship among liquidators and to identify modifiers of risk, including time since exposure, age at exposure, etc.; (b) to test the hypothesis that there is a dose-related increased risk of multiple myeloma; (c) to test the hypothesis that there is a dose-related increased risk of myelodysplasial; (d) to collect and store buccal cells from about 2,000 liquidators with a wide range of dose estimates extending to well over 1 Gy for possible use in future molecular studies of their DNA.
RATIONALE: Giving chemotherapy drugs, such as fludarabine and cyclophosphamide, and total-body irradiation before a donor umbilical cord blood stem cell transplant helps stop the growth of cancer cells and prepares the patient's bone marrow for the 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 and mycophenolate mofetil may stop this from happening. PURPOSE: This phase II trial is studying how well giving fludarabine and cyclophosphamide together with total-body irradiation works in treating patients who are undergoing an umbilical cord blood transplant for hematologic cancer.
The major purpose of this study is to evaluate the curative potential of white cell growth hormone (G-CSF)-stimulated bone marrow cells in allogeneic bone marrow transplants. Patients with cancers or blood diseases, who have poor potential for a cure with standard treatment, will be able to participate in the study. Donors will receive the white cell growth hormone (G-CSF) as a shot (injection) in their arm once a day for three days before they donate their bone marrow cells. Total body irradiation and/or chemotherapy will be given first to prepare the patient's body for the infusion of new bone marrow cells from the donor. Two medicines (cyclosporine and methotrexate) will be used to prevent the new bone marrow cells (graft) from attacking the patient's body (host) (graft-versus-host disease; GVHD). Certain safety checkpoints were built into the study if unwanted/unexpected events were to occur. If the outcomes appear better than could be expected, this will provide a bridge to extend this current approach for other innovative therapies.
This research study goal is to analyze the plasma and the cells that make up part of the immune system. We want to learn how the plasma and cells work. These may influence why one person will develop an infection and another will not, or why one person develops severe symptoms of a disease while others remain without symptoms.
This study will examine whether the combination of two anaesthetic medications, propofol and remifentanil, is suitable for short duration surgical procedures, providing a shorter recovery time and fewer side effects than either drug used alone.
This is a research study involving the treatment of leukemia or lymphoma (lymph gland cancer) in adults who have leukemia or lymphoma that is unlikely to be cured with regular anticancer drugs or radiation treatments.
