Filter by:RATIONALE: Questionnaires that measure quality-of-life may improve the health care team's ability to plan supportive care for patients undergoing donor bone marrow transplantation. PURPOSE: This clinical trial is studying quality of life in patients who are undergoing donor bone marrow transplantation.
The purpose of this study is to determine the safety and efficacy of TLK199 Tablets in patients with Myelodysplastic Syndrome (MDS)
RATIONALE: Drugs used in chemotherapy, such as arsenic trioxide and dexamethasone, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Sometimes when chemotherapy is given, it does not stop the growth of cancer cells. The cancer is said to be resistant to chemotherapy. Giving ascorbic acid may reduce drug resistance and allow the cancer cells to be killed. Thalidomide may stop the growth of cancer cells by blocking blood flow to the cancer. Giving arsenic trioxide together with ascorbic acid, dexamethasone, and thalidomide may kill more cancer cells. PURPOSE: This phase II trial is studying how well giving arsenic trioxide together with ascorbic acid, dexamethasone, and thalidomide works in treating patients with chronic idiopathic myelofibrosis or myelodysplastic or myeloproliferative disorders.
RATIONALE: Drugs used in chemotherapy, such as arsenic trioxide and gemtuzumab ozogamicin, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more cancer cells. PURPOSE: This phase II trial is studying how well giving arsenic trioxide together with gemtuzumab ozogamicin works in treating patients with advanced myelodysplastic syndromes.
The primary purpose of this study is to evaluate the safety and efficacy of cord blood transplantation for adult patients with hematologic malignancies including refractory acute leukemia. The transplant procedure was determined in detail according to the previously published report showing a high survival, so that the investigators could expect a similar result.
This study will test whether certain patients with myelodysplastic syndrome (MDS), acute myeloid leukemia (AML) or chronic myeloid leukemia (CML) can safely be vaccinated with two peptide vaccines derived from proteins called proteinase 3 (PR1) and Wilm's tumor-1 (WT1). These proteins are produced in large amounts by cells of MDS, AML and CML patients. The peptides are combined with an "adjuvant" called Montanide to make the vaccines, and the vaccines are given with GM-CSF (sargramostim). Both Montanide and sargramostim help the immune system respond to the vaccines. The vaccines then activate the immune system to make specialized cells that search out and kill the MDS, AML and CML cells containing the two proteins. Patients with MDS, AML or CML who are 18 years of age or older may be eligible for this study. Candidates are screened with a medical history and physical examination, blood tests, chest x-ray, and bone marrow aspirate and biopsy. For the bone marrow biopsy, the area of the hip is anesthetized and a special needle is used to draw marrow from the hipbone. Participants receive an injection (shot) of each peptide vaccine into deep tissue of the upper arm, upper leg, or the abdomen and two separate shots of sargramostim in the same area as the vaccine shots. Patients' vital signs (heart rate, breathing rate, temperature, blood pressure) are measured before and after they receive the vaccines and they are watched for 2 hours after the shots for possible side effects, such as chills, pain at the injection site, stomach upset, allergic reaction, low blood counts, and infection. Patients return to the clinic 1, 2, 3 and 4 weeks after receiving the vaccines for a brief physical evaluation and blood tests. A chest x-ray is also done at the 4-week visit. Patients may receive whole blood or platelet transfusions if needed to treat the MDS, growth factors (filgrastim, erythropoietin, or others) if needed, and medications to treat any infections that may develop.
RATIONALE: Giving chemotherapy and total-body irradiation before a donor bone marrow transplant or peripheral blood stem cell transplant helps stop the growth of cancer and abnormal cells and helps stop the patient's immune system from rejecting the donor's stem cells. When certain 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. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Removing the T cells from the donor cells before transplant may stop this from happening. PURPOSE: This randomized phase III trial is studying donor bone marrow that is treated in the laboratory using two different devices to compare how well they work in treating patients who are undergoing a donor bone marrow transplant for hematologic cancer.
RATIONALE: Bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. PURPOSE: This phase II trial is studying how well bortezomib works in treating patients with myelodysplastic syndromes.
The purpose of this study is to determine the overall response rate in patients with myelodysplastic syndromes (MDS) given a daily dosing schedule of decitabine.
RATIONALE: Giving low doses of chemotherapy, such as fludarabine, and radiation therapy before a donor bone marrow or 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 cyclophosphamide, mycophenolate mofetil, and tacrolimus after transplant may stop this from happening. PURPOSE: This phase I trial is studying cyclophosphamide and/or mycophenolate mofetil with or without tacrolimus to see which is the best regimen in treating patients who are undergoing a donor bone marrow or stem cell transplant for hematologic cancer.
