Fludarabine and Cyclophosphamide With or Without Oblimersen in Treating Patients With Relapsed or...
LeukemiaRATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Oblimersen may help fludarabine and cyclophosphamide kill more cancer cells by making them more sensitive to the drugs. It is not yet known if fludarabine and cyclophosphamide are more effective with or without oblimersen. PURPOSE: Randomized phase III trial to compare the effectiveness of fludarabine and cyclophosphamide with or without oblimersen in treating patients who have relapsed or refractory chronic lymphocytic leukemia.

STI571 in Treating Patients With Chronic Myelogenous Leukemia in Blast Crisis
LeukemiaRATIONALE: STI571 may interfere with the growth of cancer cells and may be an effective treatment for leukemia. PURPOSE: Phase II trial to study the effectiveness of STI571 in treating patients who have chronic myelogenous leukemia in blast crisis.

Fludarabine and Cyclophosphamide Followed by Peripheral Stem Cell Transplant in Treating Patients...
LeukemiaLymphomaRATIONALE: Giving chemotherapy drugs, such as fludarabine and cyclophosphamide, before a donor peripheral blood stem cell transplant helps stop the growth of cancer cells. It also helps stop the patient's immune system from rejecting the donor's stem cells. When the 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. PURPOSE: This phase II trial is studying how well fludarabine and cyclophosphamide followed by peripheral stem cell transplant works in treating patients with leukemia or lymphoma.

Gemcitabine in Treating Patients With Recurrent Chronic Lymphocytic Leukemia
LeukemiaRATIONALE: 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 gemcitabine in treating patients who have recurrent chronic lymphocytic leukemia.

Homoharringtonine in Treating Patients With Chronic Phase Chronic Myelogenous Leukemia
Childhood Chronic Myelogenous LeukemiaChronic Myelogenous Leukemia3 morePhase II trial to study the effectiveness of homoharringtonine in treating patients who have chronic phase chronic myelogenous leukemia. Drugs used in chemotherapy, such as homoharringtonine, work in different ways to stop cancer cells from dividing so they stop growing or die

Flavopiridol in Treating Patients With Chronic Lymphocytic Leukemia
B-cell Chronic Lymphocytic LeukemiaRefractory Chronic Lymphocytic Leukemia4 morePhase II trial to study the effectiveness of flavopiridol in treating patients who have chronic lymphocytic leukemia that has not responded to treatment with fludarabine. Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die

Pentostatin, Cyclophosphamide, and Rituximab in Treating Patients With Chronic Lymphocytic Leukemia...
LeukemiaLymphomaRATIONALE: 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. Combining chemotherapy with monoclonal antibody therapy may kill more cancer cells. PURPOSE: Phase II trial to study the effectiveness of combining pentostatin, cyclophosphamide, and rituximab in treating patients who have chronic lymphocytic leukemia or other B-cell cancers that have been treated previously.

Combination Chemotherapy, Bone Marrow Transplantation, and Radiation Therapy in Treating Infants...
LeukemiaRATIONALE: 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. Bone marrow transplantation may allow the doctor to give higher doses of chemotherapy and kill more cancer cells. Radiation therapy uses high-energy x-rays to damage cancer cells. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy, bone marrow transplantation, and radiation therapy in treating infants with acute lymphoblastic leukemia.

Combination Chemotherapy With or Without Bone Marrow Transplantation in Treating Children With Acute...
Childhood Acute Erythroleukemia (M6)Childhood Acute Megakaryocytic Leukemia (M7)14 moreRandomized phase III trial to compare the effectiveness of different chemotherapy regimens with or without bone marrow transplantation in treating children who have acute myelogenous leukemia or myelodysplastic syndrome. Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining chemotherapy with bone marrow transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more cancer cells. It is not yet known which treatment regimen is more effective for acute myelogenous leukemia or myelodysplastic syndrome

Chemotherapy in Treating Patients With Newly Diagnosed Acute or Chronic Myelogenous Leukemia or...
LeukemiaMyelodysplastic Syndromes1 moreRATIONALE: 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 high-dose cytarabine plus idarubicin in treating patients with newly diagnosed acute or chronic myelogenous leukemia or myelodysplastic syndrome.
