Active clinical trials for "Lymphoma, Extranodal NK-T-Cell"

This phase I multicenter feasibility trial is studying the safety and potential efficacy of infusing ex vivo expanded cord blood progenitors with one unmanipulated umbilical cord blood unit for transplantation following conditioning with fludarabine, cyclophosphamide and total body irradiation (TBI), and immunosuppression with cyclosporine and mycophenolate mofetil (MMF) for patients with hematologic malignancies. Chemotherapy, such as fludarabine and cyclophosphamide, and TBI given before an umbilical cord blood transplant stops the growth of leukemia cells and works to prevent the patient's immune system from rejecting the donor's stem cells. The healthy stem cells from the donor's umbilical cord blood help the patient's bone marrow make new red blood cells, white blood cells, and platelets. It may take several weeks for these new blood cells to grow. During that period of time, patients are at increased risk for bleeding and infection. Faster recovery of white blood cells may decrease the number and severity of infections. Studies have shown that counts are more likely to recover more quickly if increased numbers of cord blood cells are given with the transplant. We have developed a way of growing or "expanding" the number of cord blood cells in the lab so that there are more cells available for transplant. We are doing this study to find out whether or not giving these expanded cells along with one unexpanded cord blood unit is safe and if use of expanded cells can decrease the time it takes for white blood cells to recover after transplant. We will study the time it takes for blood counts to recover, which of the two cord blood units makes up the patient's new blood system, and how quickly immune system cells return

This phase I/II trial studies whether stopping cyclosporine before mycophenolate mofetil is better at reducing the risk of life-threatening graft-versus-host disease (GVHD) than the previous approach where mycophenolate mofetil was stopped before cyclosporine. The other reason this study is being done because at the present time there are no curative therapies known outside of stem cell transplantation for these types of cancer. Because of age or underlying health status, patients may have a higher likelihood of experiencing harm from a conventional blood stem cell transplant. This study tests whether this new blood stem cell transplant method can be made safer by changing the order and length of time that immune suppressing drugs are given after transplant.

Phase I trial to study the effectiveness of combining MS-275 with isotretinoin in treating patients who have metastatic or advanced solid tumors or lymphomas. MS-275 may stop the growth of cancer cells by blocking the enzymes necessary for their growth. Isotretinoin may help cancer cells develop into normal cells. MS-275 may increase the effectiveness of isotretinoin by making cancer cells more sensitive to the drug. MS-275 and isotretinoin may also stop the growth of solid tumors or lymphomas by stopping blood flow to the cancer. Combining MS-275 with isotretinoin may kill more cancer cells

This phase II trial studies how well tacrolimus and mycophenolate mofetil works in preventing graft-versus-host disease in patients who have undergone total-body irradiation (TBI) with or without fludarabine phosphate followed by donor peripheral blood stem cell transplant for hematologic cancer. Giving low doses of chemotherapy, such as fludarabine phosphate, and TBI before a donor peripheral blood stem cell transplant helps stop the growth of cancer cells. It also stops the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune system and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving tacrolimus and mycophenolate mofetil after the transplant may stop this from happening.

This phase I trial is studying the side effects and best dose of methoxyamine when given together with fludarabine phosphate in treating patients with relapsed or refractory hematologic malignancies. Drugs used in chemotherapy, such as methoxyamine and fludarabine phosphate, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving methoxyamine together with fludarabine phosphate may kill more cancer cells.

The purpose of this study is to evaluate the efficacy and safety of methotrexate, etoposide, pegaspargase and dexamethasone (MEDA) chemotherapy and autologous hematopoietic stem cell transplantation (Auto-HSCT) in patients with stage IV extranodal natural killer/T-cell lymphoma, nasal type.

The purpose of this research study is to compare the survival rates of patients with better risk disease undergoing hematopoietic stem cell transplant (HSCT) to the survival rates reported in the medical literature of similar patients undergoing reduced intensity HSCT from matched related donors.

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.

This phase I trial is studying the side effects and best dose of vorinostat when given together with bortezomib in treating young patients with refractory or recurrent solid tumors, including CNS tumors and lymphoma. Vorinostat and bortezomib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor.

This phase I/II trial is studying the side effects and best dose of vorinostat when given together with rituximab, ifosfamide, carboplatin, and etoposide and to see how well they work in treating patients with relapsed or refractory lymphoma or previously untreated T-cell non-Hodgkin lymphoma or mantle cell lymphoma. Vorinostat may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as rituximab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Drugs used in chemotherapy, such as ifosfamide, carboplatin, and etoposide, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving vorinostat together with rituximab and combination chemotherapy may kill more cancer cells
