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. Combining more than one drug and combining drugs in different ways may kill more cancer cells. PURPOSE: Phase II trial to study the effectiveness of chemotherapy in treating children who have very high risk acute lymphocytic 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 theophylline in treating patients who have in situ, stage I, or stage II chronic lymphocytic leukemia.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more cancer cells. Isotretinoin may help cancer cells develop into normal white blood cells. PURPOSE: Phase I/II trial of topotecan, fludarabine, cytarabine, and filgrastim followed by peripheral stem cell transplantation or isotretinoin in treating patients who have acute myeloid leukemia, myelodysplastic syndrome, or recurrent or refractory acute lymphocytic 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 506U78 in treating patients with chronic lymphocytic leukemia that has not responded to fludarabine or alkylating agents.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. PURPOSE: Phase I trial to study the effectiveness of dolastatin 10 in treating patients who have refractory or relapsed acute leukemia, chronic myelogenous leukemia in blast phase, or myelodysplastic syndrome.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Bone marrow transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy plus donor bone marrow transplantation in treating patients who have hematologic cancer.

Phase I trial to study genetic testing and the effectiveness of irinotecan in treating patients who have solid tumors and lymphoma. Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Genetic testing for a specific enzyme may help doctors determine whether side effects from or response to chemotherapy are related to a person's genetic makeup

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. PURPOSE: Phase I trial to study the effectiveness of R115777 in treating patients who have refractory or recurrent acute leukemia or chronic myelogenous leukemia.

This phase II trial is studying how well combination chemotherapy with or without donor peripheral stem cell transplant works in treating children with acute lymphoblastic leukemia. Giving combination chemotherapy before a donor peripheral 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.

Background: Combined therapy with rituximab and fludarabine is the treatment of choice for advanced stage chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL). A new technology called deoxyribonucleic acid (DNA) microarray can be used to gain knowledge about the genetic basis of CLL/SLL. Genetic studies of CLL/SLL may improve our understanding of what happens in the disease, help determine which patients are most likely to respond to treatment with fludarabine and rituximab, and identify new treatments. Objectives: -To gain further knowledge about CLL/SLL and the role of rituximab and fludarabine in treating the disease. Eligibility: -Patients 18 years of age and older with low, intermediate or high-risk CLL/SLL. Design: Patients with low-risk CLL/SLL do not receive treatment, but are followed every 3 to 6 months and donate cells (through apheresis) or lymph nodes, or both, for research purposes. Patients with intermediate or high-risk CLL/SLL receive standard treatment with rituximab and fludarabine for six 28-day treatment cycles. Rituximab is given on day 1 and fludarabine is given on days 1-5. (For the first cycle only, fludarabine treatment starts on day 2. This delay permits blood sampling on day 1 for the effect of rituximab on white blood cells.) Laboratory tests and imaging studies are done periodically to monitor drug side effects and the response to treatment. Tests include bone marrow biopsy and aspiration, blood tests and x-rays, including positron emission tomography (PET) and computed tomography (CT) scans.
