Filter by:The goal of this research study is to identify biologic and lifestyle factors that may increase a person's risk of developing acute myeloid leukemia or myelodysplastic syndrome after treatment for a previous cancer (treatment-related AML/MDS).
Objectives: Primary: To evaluate the response rate of total cytokine-immunotherapy for low-risk myelodysplastic syndromes (MDS). Secondary: To evaluate response duration, survival and side effects of the treatment.
Background: Major problems with stem cell transplantation (SCT) for cancer treatment are a lack of suitable donors for patients without a human leukocyte-antigen (HLA) tissue-matched sibling and graft-versus-host disease (GVHD), a serious side effects of immune-suppressing chemotherapy that is given to bring the cancer under control before SCT. In GVHD, the patients immune system attacks the transplanted donor cells. This study will try to improve the results of SCT from unrelated HLA-matched donors using targeted immune-depleting chemotherapy to bring the cancer under control before transplantation and to lower the chance of graft rejection, followed by reduced-intensity transplant chemotherapy to make the procedure less toxic. Objectives: To evaluate the safety and effectiveness of targeted immune-depleting chemotherapy followed by reduced-intensity transplant chemotherapy in patients with advanced cancers of the blood and immune system. To evaluate the safety and effectiveness of two different drug combinations to prevent GVHD. Both regimens have been successful in preventing GVHD, but they work by different mechanisms and affect the rebuilding of the immune system after the transplant. Eligibility: People 18 to 74 years of age with advanced or high-risk cancers of the blood and immune system who do not have a suitable HLA-matched sibling. Design: All patients receive chemotherapy before transplant to treat the cancer and suppress immune function. All patients receive a conditioning regimen of cyclophosphamide for 4 days and fludarabine for 4 days before SCT to prepare for the transplant. Patients are randomly assigned to one of two combination drug treatments to prevent GHVD as follows: - Group 1: Tacrolimus starting 3 days before SCT and continuing for 6 months, plus methotrexate on days 1, 3, 6, and 11 post-SCT, plus sirolimus starting 3 days before the SCT and continues for 6 months following SCT. - Group 2: Alemtuzumab for 4 days starting 8 days before SCT, plus cyclosporine starting 1 day before SCT and continuing for 6 months. Patients receive the donors stem cells and immune cells 2 days after completing the conditioning regimen. Patients are followed at the clinic regularly for the first 6 months after SCT, and then less often for at least 5 years. Some visits may include bone marrow aspirates and biopsies, blood draws, and other tests to monitor disease status. A skin biopsy, oral mucosa biopsy, and saliva collection are done to study chronic GVHD.
The purpose of this study is to better understand why some women who survived cancer or a related illness later develop diabetes, problems with their cholesterol, or other problems that may lead to heart disease. Because these problems may be related to treatment with total body irradiation and a stem cell transplant, the investigators will compare the rates of obesity, cholesterol problems, and diabetes between women who were treated with total body irradiation and a stem cell transplant and women who were not. The amount and location of fat stores in the abdomen is more important than overall weight or total body fat in the development of diabetes and cholesterol problems. In general, fat can be stored in several areas in the abdomen: around the organs (visceral fat), under the skin (subcutaneous fat), and in the liver (liver fat). People with higher amounts of fat around the organs (visceral fat), even those with a normal weight, are more likely to become diabetic or have high cholesterol. The amount of fat in each of these areas can be measured with an abdominal magnetic resonance imaging (MRI). In this study, the investigators will use blood tests, height, weight, waist circumference, blood pressure measurements, and an abdominal MRI to evaluate for several risk factors of heart disease, including cholesterol problems, diabetes and pre-diabetes, elevated blood pressure, and increased abdominal fat.
The goal of this clinical research study is to learn if the combination of rabbit anti-thymocyte globulin (Thymoglobulin®), sirolimus (Rapamune®), and mycophenolate mofetil (Cellcept®) can help to prevent graft versus host disease (GVHD). The safety of this drug combination will also be studied. Primary Objective: To determine efficacy and toxicity of a regimen of thymoglobulin, sirolimus and mycophenolate mofetil for prevention of acute GVHD after allogeneic stem cell transplantation from human leukocyte antigen (HLA) identical related or unrelated donors. Secondary Objective: To assess engraftment, chronic GVHD, relapse and survival.
Primary Objective: 1. To assess the self-reported symptoms and the plasma cytokine levels of AML/MDS patients pretransplantation and posttransplantation with allogeneic blood and marrow in order to identify changes in symptoms (or symptom clusters) and changes in cytokines that may be related to the conditioning regimen and/or to the development of GVHD during the 100 days posttransplant. Based on the current literature, both animal and human research, in this study we hypothesize that increases in TNF alpha to be associated with poor appetite, sleep disturbance and fatigue, but not with increases in pain, depression and numbness.
The goal of this clinical research study is to learn if combining cord blood units will be safe and result in the cells "taking" faster in recipients. The cord blood units will have their cell number increased in the lab using cells from a family member or they will be collected from an unrelated healthy donor.
The primary objective is to evaluate the efficacy of the treatment in response rate terms. Otherwise this study wants to evaluate the safety of the treatment.
The study hypotheses is that the introduction of dose escalated treosulfan, in substitution to busulfan, will reduce toxicity after allogeneic transplantation while improving myeloablation and and disease control in patients with AML and MDS not eligible for standard transplantation.
The different mechanisms of action between Antithymocyte globulin and cyclosporine can improve the effectivity when both are used in combination in patients with myelodysplastic syndrome.
