Active clinical trials for "Myelodysplastic-Myeloproliferative Diseases"

RATIONALE: Adjusting the dose of drugs used in chemotherapy such as cyclophosphamide may decrease side effects while stopping cancer cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage cancer cells. Stem cell transplantation may be able to replace immune cells that were destroyed by chemotherapy and radiation therapy used to kill cancer cells. PURPOSE: Phase I trial to study the effect on the body of dose-adjusted cyclophosphamide combined with total-body irradiation and donor stem cell transplantation in treating patients who have hematologic cancer.

RATIONALE: Giving chemotherapy drugs and total-body irradiation before a donor stem cell 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. It is not yet known which combination chemotherapy regimen is most effective when given before a donor stem cell transplant in treating aplastic anemia or hematologic cancer. PURPOSE: This phase II/III trial is studying different combination chemotherapy regimens to compare how well they work when given before donor stem cell transplant in treating patients with aplastic anemia or hematologic cancer.

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 may kill more cancer cells. White blood cells from donors may be able to kill cancer cells in patients who have hematologic cancer that has recurred following bone marrow transplantation. PURPOSE: Phase I trial to study the effectiveness of combination chemotherapy plus infusion of donated white blood cells in treating patients who have hematologic cancer that has recurred after bone marrow transplantation.

RATIONALE: Colony-stimulating factors, such as sargramostim, may increase the number of immune cells found in bone marrow or peripheral blood. PURPOSE: Phase II trial to study the effectiveness of sargramostim after bone marrow transplantation in treating patients who have myelodysplastic syndrome.

RATIONALE: Giving low doses of chemotherapy, such as melphalan and fludarabine, and a monoclonal antibody, such as alemtuzumab, before a donor bone marrow or peripheral blood stem cell transplant helps stop the growth of cancer cells. It also stops the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune system 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 after the transplant may stop this from happening. PURPOSE: This phase II trial is studying how well fludarabine, melphalan, alemtuzumab, and peripheral stem cell transplant work in treating patients with hematologic cancer.

RATIONALE: Monoclonal antibodies, such as bevacizumab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or deliver cancer-killing substances to them. PURPOSE: This phase I/II trial is to see if bevacizumab works in treating patients who have myelodysplastic syndrome.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining chemotherapy with donor bone marrow transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more cancer cells. PURPOSE: Phase II trial to study the effectiveness of busulfan and cyclophosphamide followed by bone marrow transplantation in treating patients who have acute myelogenous leukemia or myelodysplastic syndrome.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing and die. Bone marrow transplantation may be able to replace cells that were destroyed by chemotherapy. Colony-stimulating factors such as filgrastim may increase the number of immune cells found in bone marrow or peripheral blood and may help a person's immune system recover from the side effects of chemotherapy. PURPOSE: Phase II trial to study the effectiveness of chemotherapy plus bone marrow transplantation and filgrastim in treating patients who have acute myelogenous leukemia or myelodysplastic syndrome.

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 sodium salicylate in treating patients who have advanced myelodysplastic syndrome , acute myelogenous leukemia or chronic lymphocytic leukemia.

RATIONALE: Peripheral stem cell transplantation may be able to replace immune cells that were destroyed by chemotherapy or radiation therapy. PURPOSE: Randomized phase I/II trial to study the effectiveness of peripheral stem cell transplantation in treating patients who have breast cancer or hematologic cancer.
