Active clinical trials for "Myelodysplastic Syndromes"

Multi-center, survival data collection in subjects previously enrolled in study NCT00065156 (Celgene Protocol CC-5013-MDS-003).

RATIONALE: Studying samples of bone marrow and blood from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict how patients will respond to treatment. PURPOSE: This research study is looking at bone marrow and blood samples from patients with leukemia or other hematopoietic cancers.

The proposed research project will continue the application and development of a new method (biomagnetic susceptometry) that measures magnetic fields to determine how much iron is in the liver. The amount of iron in the liver is the best indicator of the amount of iron in the whole body. Measuring the amount of iron in the body is important because either too much (iron overload) or too little iron (iron deficiency) can be harmful. At present, the most reliable way to measure the amount of iron in the liver is to remove a sample of the liver by biopsy, either by surgery or by using a needle which pierces the skin and liver. Iron stored in the liver can be magnetized to a small degree when placed in a magnetic field. In patients with iron overload, the investigators previous studies have shown that magnetic measurements of liver iron in patients with iron overload are quantitatively equivalent to biochemical determinations on tissue obtained by biopsy. In the past the investigators have developed a device to measure the amount of magnetization, which was called a SQUID (Superconducting QUantum Interference Device) susceptometer. This device was validated and in use for over 20 years. The safety, ease, rapidity and comfort of magnetic measurements make frequent, serial studies technically feasible and practically acceptable to patients. The investigators have now developed a new susceptometer, which uses very similar technology to the SQUID, but the investigators believe is more accurate and precise. This study aims to validate this new instrument. The investigators will do prospective, serial studies of the diagnosis and management of patients with iron overload, including thalassemia major (Cooley's anemia), sickle cell disease, aplastic anemia, myelodysplasia, hereditary hemochromatosis, and other disorders.

The purpose of the study is to elucidate the causative molecular events responsible for the abnormal erythropoiesis in MDS.

The purpose of this study is to determine if MultiStem® can safely be given to patients with acute leukemia, chronic myeloid leukemia, or myelodysplasia after they have received hematopoietic stem cell transplantation.

RATIONALE: Collecting and storing samples of blood, urine, and tissue from patients undergoing a donor stem cell transplant to test in the laboratory may help the study of graft-versus-host disease in the future. PURPOSE: This research study is collecting and storing tissue and DNA samples from patients undergoing a donor stem cell transplant.

RATIONALE: Collecting and storing samples of bone marrow and tissue from patients to test in the laboratory may help the study of cancer. PURPOSE: This laboratory study is comparing proteases (enzymes that break down protein) in patients with prostate cancer that has spread to the bone with patients who do not have cancer that has spread to the bone.

Primary Objectives: To compare the neuropsychiatric (NP) and neurocognitive (NC) symptoms and assess the quality of life (QOL) in older patients (age > 18) with acute myelogenous leukemia (AML) or high-risk myelodysplastic syndrome (MDS) receiving different therapies, chemotherapy (Clofarabine + ara-C) or targeted therapies (PKC412 + low-dose ara-C, or R115777 + low-dose ara-C, or decitabine, or STI + low-dose ara-C). To determine whether there is a correlation between the number of packed red blood cell (PRBC) transfusions and cognitive scores and/or QOL.

The purpose of this study is to observe the number of new cases of infections per population in a given time period and their characteristics in a pathology (myelodysplastic syndrome, MDS)that involves ineffective production (or dysplasia) of a class of blood cells.

The purpose of this observational study is to compare overall survival in older adults with myelodysplastic syndromes (MDS) who receive reduced intensity conditioning hematopoietic stem cell transplant (RIC HSCT) versus those who do not receive HSCT.
