Active clinical trials for "Lymphoma"

Bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the cancer. 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 bortezomib together with rituximab may kill more cancer cells. This phase II trial is studying how well giving bortezomib together with rituximab works as first-line therapy in treating patients with low-grade B-cell non-Hodgkin's lymphoma.

This phase I trial is studying the side effects and best dose of ispinesib in treating young patients with relapsed or refractory solid tumors or lymphoma. Drugs used in chemotherapy, such as ispinesib, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing

The purpose of this study is to determine the rate and duration of complete remission and molecular response in patients with relapsed/refractory follicular lymphoma, using a combined treatment with rituximab plus chemotherapy followed by in vivo purged peripheral blood stem cells (PBSC) mobilization and autotransplant.

Diffuse large B-cell lymphoma is a most prevalent non-Hodgkin's lymphoma. Recently the clinical results have been improved with new drugs and new modalities such as cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) every 2 weeks. Bortezomib is well known to be effective for multiple myeloma and has been being tried for other malignancies including lymphoma. The investigators will incorporate Bortezomib to CHOP every 2 weeks to further improve the clinical efficacy in diffuse large B-cell lymphoma.

This phase II trial studies the side effects and efficacy of bortezomib with ifosfamide and vinorelbine in children and young adults with Hodgkin's lymphoma that was recurrent or did not respond to previous therapy. Bortezomib is an inhibitor of protein degradation. Bortezomib degrades short-lived regulatory proteins in the cell, and has been reported to increase the tumor cells. Bortezomib may increase the effectiveness of ifosfamide and vinorelbine (two standard drugs given to children with Hodgkin Lymphoma that has come back after initial treatment) by making cancer cells more sensitive to effectiveness of standard chemotherapy by preventing anti-death responses in these drugs. Giving bortezomib together with ifosfamide and vinorelbine tartrate should kill more cancer cells than are killed with ifosfamide and vinorelbine alone.

RATIONALE: Drugs used in chemotherapy, such as ifosfamide, etoposide, and carboplatin, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. 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 colony-stimulating factors, such as G-CSF, helps stem cells move from the patient's bone marrow to the blood so they can be collected and stored for peripheral stem cell transplant. Giving more chemotherapy, such as cyclophosphamide, carmustine, and etoposide, and total-body irradiation prepares the patient's bone marrow for the stem cell transplant. The stem cells are then returned to the patient to replace the blood-forming cells that were destroyed by the chemotherapy and radiation therapy. More radiation therapy is given after transplant to kill any remaining cancer cells. PURPOSE: This phase II trial is studying how well autologous peripheral stem cell transplant works in treating patients with non-Hodgkin's lymphoma or Hodgkin's lymphoma.

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

The use of R-CHOP, given every two weeks, will be associated with improvements in response rate, and progression-free survival, when compared to R-CHOP given every three weeks. The addition of sargramostim will allow safer adminIstration of the dose-intensified R-CHOP, while at the same time, improving the functional capability of the macrophages, and thus increasing the likelihood of improved clinical response and disease-free survival. The current phase II study is being proposed in order to develop preliminary data on the efficacy and toxicity of this approach, for future study in larger, phase III randomized trials. Laboratory correlates of response will also be studied, including activation markers on monocytes/macrophages before and after sargramostim exposure; and presence or absence of informative Fc gamma III polymorphisms.

RATIONALE: LMB-2 immunotoxin can locate cancer cells and kill them without harming normal cells. PURPOSE: This phase I trial is studying the side effects and best dose of LMB-2 immunotoxin in treating young patients with relapsed or refractory leukemia or lymphoma.

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.
