Active clinical trials for "Leukemia, Lymphoid"

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Monoclonal antibodies such as alemtuzumab can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. PURPOSE: Phase II trial to study the effectiveness of fludarabine followed by alemtuzumab in treating patients who have chronic lymphocytic leukemia.

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 chemotherapy is more effective for chronic lymphocytic leukemia. PURPOSE: This randomized phase III trial is studying chlorambucil to see how well it works compared to fludarabine and cyclophosphamide or fludarabine alone in treating patients with newly diagnosed chronic lymphocytic 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-2 may stimulate a person's white blood cells to kill cancer cells. Combining rituximab with interleukin-2 may kill more cancer cells. Phase I trial to study the effectiveness of rituximab plus interleukin-2 in treating patients who have hematologic cancer.

Phase II trial to study the effectiveness of combining flavopiridol and cytarabine with mitoxantrone in treating patients who have acute leukemia. Drugs used in chemotherapy work in different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one drug may kill more cancer cells.

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. This phase II trial is studying several different combination chemotherapy regimens to see how well they work in treating patients with newly diagnosed acute lymphoblastic leukemia

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.

Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Phase I trial to study the effectiveness of imatinib mesylate in treating patients who have advanced cancer and liver dysfunction

Monoclonal antibodies can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. Phase I trial to study the effectiveness of monoclonal antibody therapy in treating patients who have chronic lymphocytic leukemia, lymphocytic lymphoma, acute lymphoblastic leukemia, or acute myeloid leukemia.

RATIONALE: Monoclonal antibodies can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. PURPOSE: Phase I trial to study the effectiveness of monoclonal antibody therapy in treating patients who have chronic lymphocytic leukemia.

The purpose of this study is to provide treatment for patients who have chronic lymphocytic leukemia (CLL), and to compare the use of rituximab added to fludarabine+cyclophosphamide (FC) with FC alone, to determine if rituximab lengthens the time a patient remains free of leukemia symptoms.
