Filter by:RATIONALE: Giving chemotherapy drugs 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 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 donor bone marrow transplant works in treating patients with hematologic cancers.
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 use different ways to stop tumor cells from dividing so they stop growing or die. Amifostine may improve blood counts in patients with myelodysplastic syndrome. Combining azacitidine with amifostine may kill more cancer cells. PURPOSE: Phase II trial to study the effectiveness of azacitidine plus amifostine 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 more than one drug may kill more cancer cells. PURPOSE: Phase I trial to study the effectiveness of fludarabine, carboplatin, and topotecan in treating patients who have relapsed or refractory acute leukemia or advanced myelodysplastic syndrome.
RATIONALE: Peripheral stem cell transplantation may be able to replace immune cells that were destroyed by the chemotherapy or radiation therapy used to kill tumor cells. Sometimes the transplanted cells are rejected by the body's normal tissues. Transplanting donated cells that have been treated with psoralen may prevent this from happening. PURPOSE: Phase I trial to study the effectiveness of chemotherapy, radiation therapy, and psoralen-treated donor cells in treating patients who are undergoing peripheral stem cell transplantation for hematologic cancer.
Phase I trial to study the effectiveness of PS-341 in treating patients who have refractory or relapsed acute myeloid leukemia, acute lymphoblastic leukemia, chronic myeloid leukemia in blast phase, or myelodysplastic syndrome. PS-341 may stop the growth of cancer cells by blocking the enzymes necessary for cancer cell growth
The 5 q minus syndrome is a condition that occurs due to a missing segment of chromosome 5 in the normal genetic make-up of the cells responsible for forming blood cells. The condition causes patients to have the inability to make blood normally. Many patients with this syndrome need transfusions of red blood cells, platelets, and/or white blood cells. Low levels of platelets may cause the patient to bleed easily and low levels of whit blood cells make the patient susceptible to infections. A small number of patients with 5 q minus syndrome develop leukemia, which is often untreatable with chemotherapy. Researchers believe that one of the genes missing in 5 q minus syndrome is the gene responsible for making folic acid active in the body. Folic acid is a vitamin required for normal blood production. The purpose of this study to test the effectiveness of a drug called leucovorin for the treatment of 5 q minus syndrome. Leucovorin is an active form of the vitamin folic acid that does not require the missing genes to activate it. Patients participating in this study may or may not improve with leucovorin treatment. However, the study will improve researchers understanding of the disease and may lead other potential therapies for the disease.
Vaccines made from peptides that are found on leukemia cells may make the body build an immune response and kill cancer cells. Combining vaccine therapy with the immune adjuvant Montanide ISA-51 may be a more effective treatment for chronic myeloid leukemia, acute myeloid leukemia, or myelodysplastic syndrome. This phase I/II trial is studying the side effects and best dose of vaccine therapy when given with Montanide ISA-51 and to see how well they work in treating patients with chronic myeloid leukemia, acute myeloid leukemia, or myelodysplastic syndrome
RATIONALE: Peripheral stem cell transplantation may be able to replace immune cells that were destroyed by chemotherapy and radiation therapy used to kill tumor cells. PURPOSE: Phase I trial to study the effectiveness of treated donor stem cell transplantation in treating patients who have hematologic cancer.
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.
