Active clinical trials for "Lymphoproliferative Disorders"

Blood disorders such as leukemia or lymphoma or hemoglobinopathies can benefit from receiving an allogeneic (meaning that the cells are from a donor) stem cell transplant. Stem cells are created in the bone marrow. They grow into different types of blood cells that the body needs, including red blood cells, white blood cells, and platelets. In a transplant, the body's stem cells would be killed and then replaced by stem cells from the donor. Usually, patients are given very high doses of chemotherapy (drugs which kill cancer cells) prior to receiving a stem cell transplant. However, patients that are older, have received several prior treatments, or have other organ diseases are at a high risk of getting life-threatening treatment-related side effects from high doses of chemotherapy. Over the past several years, some doctors have begun to use lower doses of chemotherapy for preparing patients for a stem cell transplant. A condition that can occur after a stem cell transplant from a donor is Graft Versus Host Disease (GVHD). It is a rare but serious disorder that can strike persons whose immune system is suppressed and have received either a blood transfusion or a bone marrow transplant. Symptoms may include skin rash, intestinal problems similar to inflammation of the bowel and liver dysfunction. This research study uses a combination of lower-dose chemotherapy agents that is slightly different from those that have been used before. The medicines that will be used in this study are Fludarabine, Busulfan, both chemotherapy medicines, and Campath. Campath is a monoclonal antibody (a type of substance produced in the laboratory that binds to cancer cells). It helps the immune system see the cancer cell as something that needs to be destroyed. This research study will help us learn if using Fludarabine, Busulfan and Campath prior to an allogeneic stem cell transplant can provide treatment for blood disorders while decreasing the incidence of side effects.

This trial will determine the safety and tolerability of Pacritinib in patients with relapsed/refractory lymphoproliferative disorders.

RATIONALE: Diagnostic procedures, such as 3'-deoxy-3'-[18F] fluorothymidine (FLT) PET imaging, may help find and diagnose cancer. It may also help doctors predict a patient's response to treatment and help plan the best treatment. PURPOSE: This phase I trial is studying FLT PET imaging in patients with cancer.

This phase II trial studies the side effects and how well high-dose yttrium-90 (Y-90)-ibritumomab tiuxetan (anti-cluster of differentiation [CD]20) followed by fludarabine phosphate, low-dose total body irradiation (TBI), and donor peripheral blood stem cell transplant (PBSCT) work in treating patients with aggressive B-cell lymphoma that has returned after a period of improvement (relapsed) or has not responded to previous treatment (refractory). Radiolabeled monoclonal antibodies, such as Y-90-ibritumomab tiuxetan, can find cancer cells and carry cancer-killing substances to them with less effect on normal cells. Giving chemotherapy, such as fludarabine phosphate, and TBI before a donor PBSCT helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. However, high-dose radiolabeled antibodies also destroy healthy blood cells in the patient's body. When healthy stem cells from a donor are infused into the patient (stem cell transplant), they may help the patient's body replace these blood cells. Giving high-dose Y-90-ibritumomab tiuxetan followed by fludarabine phosphate, TBI, and donor PBSCT may be an effective treatment for patients with B-cell lymphoma.

RATIONALE: Giving chemotherapy, such as busulfan and fludarabine phosphate, before a peripheral blood stem cell transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving methotrexate, tacrolimus, and antithymocyte globulin before and after the transplant may stop this from happening. Once the donated stem cells begin working, the patient's immune system may see the remaining cancer cells as not belonging in the patient's body and destroy them (called graft-versus-tumor effect). Giving an infusion of the donor's white blood cells (donor lymphocyte infusion) may boost this effect. PURPOSE: This phase II trial is studying how well donor stem cell transplant works in treating patients with relapsed hematologic malignancies or secondary myelodysplasia previously treated with high-dose chemotherapy and autologous stem cell transplant .

The purpose of this study is to evaluate how safe and effective the combination of two different drugs (brentuximab vedotin and rituximab) is in patients with certain types of lymphoma. This study is for patients who have a type of lymphoma that expresses a tumor marker called CD30 and/or a type that is associated with the Epstein-Barr virus (EBV-related lymphoma) and who have not yet received any treatment for their cancer, except for dose-reduction or discontinuation (stoppage) of medications used to prevent rejection of transplanted organs (for those patients who have undergone transplantation). This study is investigating the combination of brentuximab vedotin and rituximab as a first treatment for lymphoma patients

Phase I trial to study the effectiveness of radiolabeled monoclonal antibody therapy with or without peripheral stem cell transplantation in treating patients who have recurrent or refractory lymphoma. Radiolabeled monoclonal antibodies can locate cancer cells and deliver radioactive tumor-killing substances to them without harming normal cells. Peripheral stem cell transplantation may be able to replace immune cells that were destroyed by anticancer therapy

The cause of blood and bone marrow cancers is poorly understood; however, most research focuses on how cancer cells grow and develop. Because the causes of these cancers are unknown, current treatments may be unnecessarily harsh and often do not provide a cure. Identifying the causes of blood cancers would allow for the development of treatments that are more likely to provide a cure. To find the causes of blood and bone marrow cancers, we will look for specific cancer cell abnormalities that are responsible for cancer cell growth. We will then look to see if drugs that can reverse these abnormalities can kill cancer cells.

OBJECTIVES: I. Provide curative immunoreconstituting allogeneic bone marrow transplantation for patients with primary immunodeficiencies. II. Determine relevant outcomes of this treatment in these patients including quality of survival, extent of morbidity and mortality from complications of the treatment (e.g., graft versus host disease, regimen related toxicities, B- cell lymphoproliferative disease), and completeness of functional immunoreconstitution.

This pilot phase II trial studies how well giving donor T cells after donor stem cell transplant works in treating patients with hematologic malignancies. In a donor stem cell transplant, the donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Giving an infusion of the donor's T cells (donor lymphocyte infusion) after the transplant may help increase this effect.
