Active clinical trials for "Lymphoma, Non-Hodgkin"

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one drug may kill more cancer cells. PURPOSE: Phase I trial to study the effectiveness of combination chemotherapy consisting of methotrexate and cyclophosphamide in treating children who have stage III or stage IV non-Hodgkin's lymphoma or acute lymphoblastic leukemia.

Monoclonal antibodies, such as rituximab, can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. Interleukin-12 may kill cancer cells by stopping blood flow to the tumor and by stimulating a person's white blood cells to kill cancer cells. Combining rituximab with interleukin-12 may kill more cancer cells. This randomized phase II trial is comparing how well giving rituximab together with two different schedules of interleukin-12 works in treating patients with B-cell non-Hodgkin lymphoma.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Monoclonal antibodies such as rituximab can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. Combining chemotherapy with monoclonal antibody therapy may kill more cancer cells. PURPOSE: Phase II trial to study the effectiveness of combining pentostatin and rituximab in treating patients who have non-Hodgkin's lymphoma or chronic lymphocytic leukemia.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Monoclonal antibodies such as rituximab can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. It is not yet known whether combination chemotherapy is more effective with or without rituximab in treating aggressive non-Hodgkin's lymphoma. PURPOSE: This randomized phase III trial is studying how well giving cyclophosphamide, doxorubicin, vincristine, and prednisone together with or without rituximab works in treating older patients who have aggressive non-Hodgkin's lymphoma. (This trial is no longer randomized as of 6/2005).

RATIONALE: Radiolabeled monoclonal antibodies can locate tumor cells and deliver radiation to them without harming normal cells. PURPOSE: Phase II trial to study the effectiveness of rituximab and ibritumomab tiuxetan in treating patients who have relapsed or refractory non-Hodgkin's lymphoma.

RATIONALE: Monoclonal antibodies such as rituximab can locate cancer cells and deliver cancer-killing substances to them without harming normal cells. Radiolabeled monoclonal antibodies can locate and deliver radioactive cancer-killing substances. PURPOSE: Phase I/II trial to study the effectiveness of combining radiolabeled monoclonal antibodies with rituximab in treating patients who have non-Hodgkin's lymphoma that has not responded to high-dose chemotherapy and autologous stem cell transplantation.

RATIONALE: Monoclonal antibodies such as rituximab can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining chemotherapy with peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more cancer cells. It is not yet known if combining rituximab with cyclophosphamide is more effective than cyclophosphamide alone in stimulating peripheral stem cells for transplantation. PURPOSE: This randomized phase II trial is studying how well giving cyclophosphamide with or without rituximab followed by chemotherapy and peripheral stem cell transplantation works in treating patients with recurrent non-Hodgkin's lymphoma.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. PURPOSE: Phase II trial to study the effectiveness of liposomal vincristine in treating patients who have refractory or relapsed non-Hodgkin's lymphoma.

When patients relapse after primary chemotherapy for Non-Hodgkin's lymphoma, they may be eligible to receive high-dose chemotherapy with autologous stem cell support. Unfortunately high-dose chemotherapy is curative in less than half the patients who receive it. This study is being conducted to determine the safety, side effects, and the ability to respond to an investigational vaccine that consists of tumor-pulsed dendritic cells given with an immune stimulating drug called interleukin-2. The patient must have a lymphomatous node accessible for excision to prepare the vaccine. Dendritic cells are immune cells that are obtained from the blood, and are important in the body's immune response to foreign substances. This study will examine the response of the immune system after three vaccinations (composed of dendritic cells, which have been exposed to dead fragments of lymphoma cells) given beginning three months after transplant. Vaccination may result in sensitizing the patient's dendritic cells to his lymphoma cells, potentially resulting in an immune response against the lymphoma. Twelve patients will be treated on study.

Phase II trial to study the effectiveness of oxaliplatin in treating patients who have relapsed or refractory non-Hodgkin's lymphoma. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die
