AIDS-related Diffuse Large Cell LymphomaAIDS-related Diffuse Mixed Cell Lymphoma19 moreDrugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. This phase II trial is studying how well topotecan hydrochloride works in treating children with meningeal cancer that has not responded to previous treatment

Gemtuzumab Ozogamicin and High-Dose Cytarabine in Treating Patients With Relapsed or Refractory...
LeukemiaRATIONALE: Monoclonal antibodies, such as gemtuzumab ozogamicin, can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. Drugs used in chemotherapy, such as cytarabine, use different ways to stop cancer cells from dividing so they stop growing or die. Combining gemtuzumab ozogamicin with cytarabine may kill more cancer cells. PURPOSE: Phase II trial to study the effectiveness of combining gemtuzumab ozogamicin with high-dose cytarabine in treating patients who have relapsed or refractory acute myeloid leukemia.

Docetaxel in Treating Children With Relapsed or Refractory Acute Lymphoblastic or Acute Myeloid...
LeukemiaRATIONALE: Drugs used in chemotherapy, such as docetaxel, work in different ways to stop cancer cells from dividing so they stop growing or die. PURPOSE: Phase II trial to study the effectiveness of docetaxel in treating children who have relapsed or refractory acute lymphoblastic or acute myeloid leukemia.

LeukemiaRATIONALE: Monoclonal antibodies such as gemtuzumab ozogamicin can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. Oblimersen may help gemtuzumab ozogamicin kill more cancer cells by making cancer cells more sensitive to the drug. PURPOSE: Phase II trial to study the effectiveness of combining oblimersen and gemtuzumab ozogamicin in treating older patients who have relapsed acute myeloid leukemia.

Chemotherapy in Treating Patients With Acute Lymphoblastic Leukemia and Diffuse Non-Hodgkin's Lymphoma...
LeukemiaLymphomaRATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of two treatment regimens for patients in developing countries with diffuse non-Hodgkin's lymphoma and acute lymphoblastic leukemia.

Troxacitabine in Treating Patients With Chronic Myelogenous 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 troxacitabine in treating patients who have blast phase chronic myelogenous leukemia.

Phase I/II Study of Genasense in Patients With Chronic Lymphocytic Leukemia
Chronic Lymphocytic LeukemiaCLLThis non-randomized study will test the safety and effectiveness of Genasense in patients with CLL.

Immunotoxin Therapy in Treating Patients With Hairy Cell Leukemia
LeukemiaRATIONALE: An immunotoxin can locate cancer cells and kill them without harming normal cells. This may be an effective treatment for hairy cell leukemia. PURPOSE: Phase I trial to study the effectiveness of BL22 immunotoxin in treating patients who have refractory or recurrent hairy cell leukemia.

Tipifarnib in Treating Young Patients With Refractory Leukemia
LeukemiaRATIONALE: Tipifarnib may stop the growth of cancer cells by blocking the enzymes necessary for cancer cell growth. PURPOSE: Phase I trial to study the effectiveness of tipifarnib in treating young patients who have refractory leukemia.

Reduced Intensity Donor Stem Cell Transplant in Treating Patients With High Risk Acute Lymphocytic...
Adult Acute Lymphoblastic Leukemia in RemissionChildhood Acute Lymphoblastic Leukemia in Remission2 moreThe reason for doing this study is to determine whether a new method of blood stem cell transplant (also known as bone marrow transplant) is able to treat acute lymphocytic leukemia. Blood stem cells are the "seed cells" necessary to make all blood cells. This new method of transplant uses a combination of low dose radiation and chemotherapy that may be less toxic and cause less harm than a conventional transplant. This lower dose transplant is called a "nonmyeloablative transplant". Researchers want to see if using less radiation and less chemotherapy combined with new immune suppressing drugs after the transplant will help a stem cell transplant to work. Researchers hope that this treatment will cure acute lymphocytic leukemia with fewer side effects. Researchers are hoping to see a mixture of recipient and donor blood cells after transplant. This mixture of donor and recipient blood cells is called "mixed chimerism". Researchers hope that donor cells will attack and eliminate the leukemia. This is called the "graft-versus-leukemia" effect. In addition, after the transplant, white blood cells from the donor may be given to enhance or "boost" the graft-versus-leukemia effect, and hopefully remove all remaining cancer cells. This study is being done because at the present time blood stem cell transplantation (or bone marrow transplantation) is the only known curative therapy for acute lymphocytic leukemia. Because of age or underlying health status acute lymphocytic leukemia patients have a higher likelihood of experiencing severe harm from a conventional blood stem cell transplant. Researchers are doing this study to see if this new nonmyeloablative method of low dose radiation and low dose chemotherapy given before transplant and immune suppressive drugs after transplant will help make the transplant safer and also cure acute lymphocytic leukemia
