Active clinical trials for "Leukemia"

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 aminopterin in treating patients who have refractory leukemia.

RATIONALE: Biological therapies use different ways to stimulate the immune system and stop cancer cells from growing. Combining chemotherapy and peripheral stem cell transplantation with biological therapy may kill more cancer cells. PURPOSE: Phase II trial to study the effectiveness of biological therapy with sargramostim, interleukin-2, and interferon alfa following chemotherapy and peripheral stem cell transplantation in treating patients who have cancer.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Some cancers may become resistant to chemotherapy drugs. Combining PSC 833 with chemotherapy may reduce resistance to the drugs and allow the cancer cells to be killed. Interleukin-2 may stimulate a person's white blood cells to kill leukemia cells. PURPOSE: Phase I/II trial to study the effectiveness of combination chemotherapy plus PSC 833 followed by additional chemotherapy or peripheral stem cell transplantation and interleukin-2 in treating patients with untreated acute myelogenous leukemia.

Phase II trial to study the effectiveness of 506U78 in treating patients with recurrent or refractory hematologic cancer. 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. Combining more than one drug may kill more cancer cells. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy in treating patients with acute myeloid leukemia or myelodysplastic syndrome in first relapse or who did not achieve first remission.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. PURPOSE: Phase III trial to compare the effectiveness of combination chemotherapy in treating children who have relapsed acute lymphoblastic leukemia.

This pilot clinical trial studies low-dose total body irradiation and donor peripheral blood stem cell transplant followed by donor lymphocyte infusion in treatment patients with non-Hodgkin lymphoma, chronic lymphocytic leukemia, or multiple myeloma. Giving total-body irradiation before a donor peripheral blood stem cell transplant helps stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer cells. When healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. 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. Giving an infusion of the donor's white blood cells (donor lymphocyte infusion) may boost this effect.

RATIONALE: Monoclonal antibodies can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. PURPOSE: Phase II trial to study the effectiveness of monoclonal antibody therapy consisting of rituximab in treating patients with refractory or recurrent hairy cell leukemia following cladribine therapy.

RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Bone marrow transplantation may be able to replace immune cells that have been destroyed by radiation therapy used to kill tumor cells. Sometimes the transplanted cells can make an immune response against the body's normal tissues. Mycophenolate mofetil and tacrolimus may be an effective treatment for graft-versus-host disease caused by bone marrow transplantation. PURPOSE: Phase II trial to study the effectiveness of total-body irradiation, tacrolimus, and mycophenolate mofetil plus bone marrow transplantation in treating patients with hematologic cancers.

This clinical trial studies the side effects and best dose of giving fludarabine and total-body irradiation (TBI) together followed by a donor stem cell transplant and cyclosporine and mycophenolate mofetil in treating human immunodeficiency virus (HIV)-positive patients with or without cancer. Giving low doses of chemotherapy, such as fludarabine, and TBI before a donor bone marrow or peripheral blood stem cell transplant helps stop the growth of cancer or abnormal cells and helps stop the patient's immune system from rejecting the donor's 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 (CSP) and mycophenolate mofetil (MMF) after the transplant may stop this from happening.
