Filter by:A Study of Bafetinib as Treatment for Patients with Relapsed or Refractory B-Cell Chronic Lymphocytic Leukemia (B-CLL).
This research trial studies a risk-based classification system for patients with newly diagnosed acute lymphoblastic leukemia. Gathering health information about patients with acute lymphoblastic leukemia may help doctors learn more about the disease and plan the best treatment.
The investigators are interested in identifying patient-specific factors related to donor chimerism in patients who receive nonmyeloablative hematopoietic stem cell transplants from haploidentical donors. We will look how patients' bodies break down and immediately respond to cyclophosphamide, fludarabine and mycophenolate mofetil.
This phase I/II trial is studying the side effects and best dose of bendamustine hydrochloride when given together with idarubicin in treating older patients with previously untreated acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS). Drugs used in chemotherapy, such as bendamustine hydrochloride or idarubicin, 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
RATIONALE: Studying samples of blood or tumor tissue from patients with cancer in the laboratory may help doctors learn about changes that occur in DNA and identify biomarkers related to cancer. PURPOSE: This research study is studying biomarker changes in samples from young patients with acute myeloid leukemia.
Background: - Multiple myeloma (MM), a type of cancer that affects the white blood cells, is often preceded by a precancerous disorder known as monoclonal gammopathy of undetermined significance (MGUS). Farmers and other agricultural workers have a higher risk of developing MGUS and MM, possibly because of their exposure to certain pesticides. Researchers are interested in studying biological specimens taken from participants in the Agricultural Health Study - specifically, pesticide applicators at least 50 years of age who do not have cancer- to better understand the development of MGUS and MM. Objectives: - To collect biological specimens from Agricultural Health Study participants for further research. - To examine the relationship between pesticide exposure and MGUS/MM. Eligibility: - Male pesticide applicators who are over 50 years of age, cancer-free, and participating in the Agricultural Health Study. Design: - Two groups of participants will complete the study: a general group and a smaller group of individuals who have been exposed to the pesticide diazinon. - All participants will receive an initial contact letter with information about the study, followed by a phone call to administer a screening questionnaire and arrange a home visit from a researcher within the next month. - Participants will receive by mail a urine specimen kit that will be collected at the home visit. - During the home visit, a study researcher will take blood samples and collect the urine sample, and will administer another questionnaire. - Participants in the group exposed to diazinon will have three home visits for the study: (1) prior to pesticide exposure, (2) the day after participants stop using diazinon, and (3) about 21 days after the second visit. The first visit will take place in the off-season from January to March; the second and third visits will be conducted between April and August. - No treatment will be provided as part of this study.
RATIONALE: Studying samples of blood and tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. PURPOSE: This research study is studying blood and tumor tissue samples from young patients with acute myeloid leukemia.
RATIONALE: Studying samples of DNA from patients receiving gemtuzumab ozogamicin may help doctors learn more about the effects of gemtuzumab ozogamicin on cells. It may also help doctors understand how well patients respond to treatment. PURPOSE: This research study is studying biomarkers in DNA samples from younger patients with newly diagnosed with acute myeloid leukemia receiving gemtuzumab ozogamicin.
RATIONALE: Studying samples of blood or tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. PURPOSE: This research study is studying biomarkers in samples from patients with Down syndrome and acute megakaryoblastic leukemia.
The goal of this clinical research study is to find the highest tolerable dose of 4'-thio-araC (thiarabine) that can be given to patients with advanced blood cancer. The safety of this drug will also be studied and 2 different dose schedules will be tested.
