Active clinical trials for "Lymphoma, Non-Hodgkin"

RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Peripheral stem cell transplant may be able to replace immune cells that were destroyed by the chemotherapy. Monoclonal antibodies, such as rituximab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. It is not yet known if giving more than one drug (combination chemotherapy) plus peripheral stem cell transplant is more effective with or without monoclonal antibody therapy in treating non-Hodgkin's lymphoma. PURPOSE: This randomized phase III trial is studying how well chemotherapy plus peripheral stem cell transplant with or without monoclonal antibody therapy works in treating patients with relapsed non-Hodgkin's lymphoma.

This phase I/II trial studies whether a new kind of blood stem cell (bone marrow) transplant, that may be less toxic, is able to treat underlying blood cancer. Stem cells are "seed cells" necessary to make blood cells. Researchers want to see if using less radiation and less chemotherapy with new immune suppressing drugs will enable a stem cell transplant to work. Researchers are hoping to see a mixture of recipient and donor stem cells after transplant. This mixture of donor and recipient stem cells is called "mixed-chimerism". Researchers hope to see these donor cells eliminate tumor cells. This is called a "graft-versus-leukemia" response.

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 if combination chemotherapy is more effective with or without rituximab for non-Hodgkin's lymphoma. PURPOSE: Randomized phase III trial to compare the effectiveness of combination chemotherapy with or without rituximab in treating older patients who have non-Hodgkin's lymphoma.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining peripheral stem cell transplantation with more than one drug regimen may kill more tumor cells. It is not known whether receiving standard combination chemotherapy alone is more effective than receiving multiple combination chemotherapy plus peripheral stem cell transplantation for aggressive non-Hodgkin's lymphoma. PURPOSE: This randomized phase III trial is comparing giving different combination chemotherapy regimens together with peripheral stem cell transplantation to see how well they work in treating patients with newly diagnosed aggressive non-Hodgkin's lymphoma.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining bone marrow transplantation with chemotherapy may allow doctors to give higher doses of chemotherapy and kill more tumor cells. PURPOSE: This phase II trial is studying the side effects of giving a bone marrow transplant together with chemotherapy and to see how well it works in treating patients with refractory non-Hodgkin's lymphoma, Hodgkin's lymphoma, or multiple myeloma.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug and using drugs in different ways may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy in treating pediatric patients with stage III or stage IV non-Hodgkin's lymphoma.

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

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. It is not yet known which regimen of combination chemotherapy is most effective for lymphoblastic lymphoma. PURPOSE: This randomized phase III trial is studying different regimens of combination chemotherapy to compare how well they work in treating children or adolescents with newly diagnosed stage III or stage IV lymphoblastic lymphoma.

Phase I trial to study the effectiveness of monoclonal antibody therapy in treating patients who have recurrent non-Hodgkin's lymphoma. Monoclonal antibodies can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells.

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. It is not yet known whether combination chemotherapy plus rituximab is more effective than combination chemotherapy alone for non-Hodgkin's lymphoma. PURPOSE: Randomized phase III trial to compare the effectiveness of combination chemotherapy with or without rituximab in treating patients who have newly diagnosed non-Hodgkin's lymphoma that has not been treated previously.
