Active clinical trials for "Preleukemia"

RATIONALE: 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. Peripheral stem cell or bone marrow transplantation may be able to replace immune cells that were destroyed by chemotherapy and radiation therapy used to kill cancer cells. PURPOSE: Phase II trial to study the effectiveness of gemtuzumab ozogamicin combined with fludarabine and total-body irradiation followed by donor peripheral stem cell or bone marrow transplantation in treating patients who have advanced acute myeloid leukemia or myelodysplastic syndrome.

This phase I trial studies the side effects and best dose of iodine I 131 monoclonal antibody BC8 when given together with fludarabine phosphate and low-dose total-body irradiation followed by donor stem cell transplant and immunosuppression therapy in treating older patients with acute myeloid leukemia or high-risk myelodysplastic syndromes that cannot be controlled with treatment. Radiolabeled monoclonal antibodies, such as iodine I 131 monoclonal antibody BC8, can find cancer cells and carry cancer-killing substances to them. Giving chemotherapy, such as fludarabine phosphate, and total-body irradiation before a donor peripheral blood stem cell transplant helps stop the growth of cancer or abnormal cells. It may also 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. The donated stem cells may also replace the patient's immune cells and help destroy any remaining cancer cells. Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving radiolabeled monoclonal antibody therapy together with fludarabine phosphate and total-body irradiation before the transplant together with cyclosporine and mycophenolate mofetil 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 BMS-214662 in treating patients who have acute leukemia, myelodysplastic syndrome, or chronic myeloid leukemia in blast phase

RATIONALE: Peripheral stem cell transplantation may be able to replace immune cells that were destroyed by chemotherapy or radiation therapy used to kill tumor cells. It is not yet known if total-body irradiation plus peripheral stem cell transplantation is more effective with busulfan or with cyclophosphamide for myelodysplastic syndrome or acute myeloid leukemia. PURPOSE: Randomized phase III trial to compare the effectiveness of busulfan with that of cyclophosphamide in patients undergoing total-body irradiation plus peripheral stem cell transplantation for advanced myelodysplastic syndrome or related acute myeloid leukemia.

RATIONALE: Bone marrow transplantation may be able to replace immune cells that were destroyed by chemotherapy or radiation therapy used to kill tumor cells. Sometimes the transplanted cells can make an immune response against the body's normal tissues. Treatment of the donor bone marrow with the patient's white blood cells and a monoclonal antibody may prevent this from happening. PURPOSE: Phase I trial to study the effectiveness of bone marrow transplantation with specially treated bone marrow in treating patients who have hematologic cancer that has not responded to previous therapy.

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 if stronger doses of chemotherapy given over a longer period of time are as well tolerated or as effective as less intensive chemotherapy. PURPOSE: This randomized phase III trial is studying intensive regimens of chemotherapy to see how well they work compared to nonintensive regimens of chemotherapy in treating older patients with acute myeloid leukemia or myelodysplastic syndrome.

RATIONALE: Giving chemotherapy and total-body irradiation before a donor bone marrow 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 stem cells from a related or unrelated donor, that closely matches the patient's blood, are infused into the patient they may help the patient's bone marrow to make stem cells, red blood cells, white blood cells, and platelets. PURPOSE: This phase II trial is studying how well donor bone marrow transplant works in treating patients with leukemia, lymphoma, or nonmalignant hematologic disorders.

RATIONALE: Drugs used in chemotherapy, such as VNP40101M and hydroxyurea, work in different ways to stop cancer cells from dividing so they stop growing or die. Hydroxyurea may help VNP40101M kill more cancer cells by making cancer cells more sensitive to the drug. PURPOSE: This phase II trial is studying how well giving VNP40101M with hydroxyurea works in treating patients with acute myelogenous leukemia or high-risk myelodysplasia.

RATIONALE: Monoclonal antibodies, such as infliximab, can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. PURPOSE: Randomized phase II trial to study the effectiveness of infliximab in treating patients who have myelodysplastic syndrome.

The goal of this clinical research study is to learn if clofarabine, when given in combination with ara-C (cytarabine), can help to improve the disease's response to therapy and to increase the duration of response in patients who are 50 years or older with leukemia. The safety of this combination treatment will also be studied.
