Active clinical trials for "Lymphoma, B-Cell, Marginal Zone"

This phase II trial studies giving rituximab before and after a donor peripheral blood stem cell transplant in patients with B-cell lymphoma that does not respond to treatment (refractory) or has come back after a period of improvement (relapsed). Monoclonal antibodies, such as rituximab, can interfere with the ability of cancer cells to grow and spread. Giving rituximab before and after a donor peripheral blood stem cell transplant may help stop cancer from coming back and may help keep the patient's immune system from rejecting the donor's stem cells.

RATIONALE: Biological therapies, such as fusion protein cytokine therapy, may stimulate the immune system in different ways and stop cancer cells from growing. 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. Giving fusion protein cytokine therapy together with rituximab may kill more cancer cells. PURPOSE: This phase I trial is studying the side effects and best dose of fusion protein cytokine therapy when given after rituximab in treating patients with B-cell non-Hodgkin lymphoma.

This phase I trial is studying the side effects of giving genetically engineered lymphocytes together with cyclophosphamide and aldesleukin in treating patients with relapsed or refractory mantle cell lymphoma or indolent B-cell non-Hodgkin lymphoma. Placing a gene that has been created in the laboratory into white blood cells may make the body build an immune response to kill cancer cells. Drugs used in chemotherapy, such as cyclophosphamide, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Aldesleukin may stimulate the white blood cells to kill lymphoma cells. Giving genetically engineered lymphocytes together with cyclophosphamide and aldesleukin may be an effective treatment for mantle cell lymphoma and B-cell non-Hodgkin lymphoma

RATIONALE: Biological therapies, such as agatolimod sodium, may stimulate the immune system in different ways and stop cancer cells from growing. 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. Radiolabeled monoclonal antibodies, such as yttrium Y 90 ibritumomab tiuxetan, can find cancer cells and carry cancer-killing substances to them without harming normal cells. Giving agatolimod sodium together with rituximab and yttrium Y 90 ibritumomab tiuxetan may kill more cancer cells. PURPOSE: This phase I/II trial is studying the side effects and best dose of agatolimod sodium when given together with rituximab and yttrium Y 90 ibritumomab tiuxetan and to see how well it works in treating patients with recurrent or refractory non-Hodgkin lymphoma.

This phase II trial studies how well giving fludarabine phosphate, cyclophosphamide, tacrolimus, mycophenolate mofetil and total-body irradiation together with a donor bone marrow transplant works in treating patients with high-risk hematologic cancer. Giving low doses of chemotherapy, such as fludarabine phosphate and cyclophosphamide, and total-body irradiation before a donor bone marrow transplant helps stop the growth of cancer cells by stopping them from dividing or killing them. Giving cyclophosphamide after transplant may also stop the patient's immune system from rejecting the donor's bone marrow stem cells. The donated stem cells may replace the patient's immune system cells 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 studies the side effects and best dose of fludarabine (fludarabine phosphate) when given together with iodine I 131 tositumomab in treating older patients who are undergoing an autologous or syngeneic stem cell transplant for relapsed or refractory B-cell non-Hodgkin's lymphoma (NHL). Radiolabeled monoclonal antibodies, such as iodine I 131 tositumomab, can find cancer cells and carry cancer-killing substances to them without harming normal cells. Drugs used in chemotherapy, such as fludarabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. A peripheral stem cell transplant may be able to replace blood-forming cells that were destroyed by chemotherapy and radiation therapy. Giving iodine I 131 tositumomab together with fludarabine followed by autologous stem cell transplant may be an effective treatment for NHL

This phase II trial studies how well tipifarnib works in treating patients with relapsed or refractory non-Hodgkin's lymphoma. Tipifarnib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Tipifarnib may be an effective treatment for non-Hodgkin's lymphoma.

This phase II trial is studying the side effects and best dose of alemtuzumab when given together with fludarabine phosphate and total-body irradiation followed by cyclosporine and mycophenolate mofetil in treating patients who are undergoing a donor stem cell transplant for hematologic cancer. Giving low doses of chemotherapy, such as fludarabine phosphate, a monoclonal antibody, such as alemtuzumab, and radiation therapy before a donor stem cell transplant helps stop the growth of cancer cells. Giving chemotherapy or radiation therapy before or after transplant also stops the patient's immune system from rejecting the donor's bone marrow stem cells. The donated stem cells may replace the patient's immune cells 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 cyclosporine and mycophenolate mofetil after the transplant may stop this from happening.

The purpose of this study is to determine the effectiveness of six cycles of concurrent fludarabine and rituximab in patients with mucosa-associated lymphoid tissue (MALT) lymphoma, marginal zone lymphoma (MZL) or CD5-, CD10-, CD20+ low-grade B cell lymphomas.
