Filter by:RATIONALE: Peripheral stem cell transplantation may be able to replace immune cells that were destroyed by chemotherapy. Sometimes the transplanted cells from a donor are rejected by the body's normal cells. Eliminating the T cells from the donor cells before transplanting them may prevent this from happening. Infusions of donor lymphocytes may decrease the body's rejection of the transplanted peripheral stem cells. PURPOSE: Phase II trial to study the effectiveness of allogeneic stem cell transplantation followed by donor lymphocyte infusions in treating patients who have hematologic cancer.
The purpose of this study is to determine the safety and efficacy of DN-101 (calcitriol) in patients with myelodysplastic syndrome who are dependent on repeat blood transfusions.
Chromosomal analysis or the study of genetic differences in patients previously untreated with AML, ALL, MDS or MM may be helpful in the diagnosis and classification of disease. It may also improve the ability to predict the course of disease and the selection of therapy. Institutions must have either an Alliance-approved cytogeneticist or an agreement from an Alliance-approved main member cytogenetics laboratory to enroll a patient on CALGB 8461. The Alliance Approved Institutional Cytogeneticists list is posted on the Alliance for Clinical Trials in Oncology website.
RATIONALE: Giving chemotherapy before a donor stem cell transplant 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. It is not yet known whether donor stem cell transplant is more effective with or without chemotherapy in treating primary myelodysplastic syndrome. PURPOSE: This phase III trial is studying how well donor stem cell transplant given with chemotherapy works and compares it with donor stem cell transplant without chemotherapy in treating children with primary myelodysplastic syndrome.
RATIONALE: Decitabine may help myelodysplasia cells develop into normal stem cells. It is not yet known if decitabine is more effective than standard supportive care in treating myelodysplastic syndrome. PURPOSE: Randomized phase III trial to compare the effectiveness of low-dose decitabine with that of standard supportive care in treating older patients who have myelodysplastic syndrome.
RATIONALE: Monoclonal antibodies such as gemtuzumab 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 gemtuzumab in treating patients who have myelodysplastic syndrome.
RATIONALE: Giving chemotherapy drugs, such as fludarabine and melphalan, before a donor bone marrow transplant or peripheral blood stem cell transplant helps stop the patient's immune system from rejecting the donor's stem cells and helps stop the growth of cancer or abnormal 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 giving combination chemotherapy followed by donor bone marrow transplant or peripheral stem cell transplant works in treating patients with hematologic cancer or genetic disorders.
RATIONALE: Umbilical cord blood or placental blood transplantation may be able to replace immune cells that were destroyed by the chemotherapy or radiation therapy that was used to kill cancer cells. PURPOSE: Phase II trial to study the effectiveness of umbilical cord blood and placental blood transplantation in treating patients who have hematologic cancer or aplastic anemia.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumors from dividing so they stop growing or die. Chemoprotective drugs, such as amifostine, may protect normal cells from the side effects of chemotherapy. PURPOSE: Phase I trial to study the effectiveness of amifostine plus combination chemotherapy in treating patients with advanced cancer.
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 arsenic trioxide in treating patients who have recurrent or refractory acute leukemia, chronic myeloid leukemia, myelodysplasia, lymphoma, or myeloma.
