Active clinical trials for "Leukemia"

This phase II/III trial studies how well eltrombopag olamine works in treating thrombocytopenia in patients with chronic myeloid leukemia or myelofibrosis receiving tyrosine kinase inhibitor therapy. Eltrombopag olamine may cause the body to make platelets after receiving treatment for chronic myeloid leukemia or myelofibrosis.

RATIONALE: DNA analysis of blood and tissue samples may help doctors predict how well patients will respond to treatment. It may also help doctors learn more about how gemtuzumab ozogamicin works in the body. PURPOSE: This research study is looking at gemtuzumab ozogamicin in DNA samples from patients with acute myeloid leukemia treated on COG-AAML0531.

This multi-center, prospective, observational study will describe the management of relapsing or refractory chronic lymphocytic leukemia (CLL) patients. Data will be collected for 2 years.

RATIONALE: Studying samples of blood, tissue, or bone marrow 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 trial is studying dexamethasone and prednisone sensitivity in samples from younger patients with high-risk B-cell precursor acute lymphoblastic leukemia.

The purpose of this study is to explore the impact of thiopurine methyltransferase (TPMT) activity on the risk of HDM-related bone marrow- and hepatotoxicity and treatment interruptions during maintenance therapy for children with ALL. Hypothesis of the study: Patients with TPMT activity compatible with TPMT low activity polymorphisms have an increased risk of toxicity following high-dose methotrexate (HDM) compared to children with normal TPMT activity.

RATIONALE: Studying samples of 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 looking at gene expression in tissue samples from patients with acute myeloid leukemia.

RATIONALE: Studying samples of 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 looking at gene expression in tissue samples from young patients with acute myeloid leukemia.

This study will evaluate the association between changes in basic cognitive and behavioral functioning by the end of chemotherapy treatment, and the later development of higher order executive functions in pediatric acute lymphoblastic leukemia (ALL). The association between acute treatment-related changes in brain integrity and subsequent brain maturation in long-term survivors of pediatric ALL will be evaluated. The association between patterns of behavioral and executive dysfunction and brain maturation in long-term survivors of pediatric ALL will be examined. The association between genetic polymorphisms in key enzyme pathways and higher order brain development in long-term survivors of pediatric ALL will be explored. The associations between biologic and behavioral indices of fatigue/sleep and higher order brain development in long-term survivors of pediatric ALL will be explored.

RATIONALE: Gathering information about how often kidney dysfunction occurs in children and young adults receiving methotrexate for acute lymphoblastic leukemia may help doctors learn more about the disease and plan the best treatment. PURPOSE: This research study is looking at kidney dysfunction in children and young adults who have received low-dose or intermediate-dose methotrexate for acute lymphoblastic leukemia.

The purpose of this registry is to record information on therapy reality of malignant lymphatic systemic diseases by office-based haematologists in Germany.
