Active clinical trials for "Leukemia, Lymphoid"

A minority of patients with adult acute lymphoblastic leukemia (ALL) relapse are rescued. The aim of this population-based study was to assess the results of reinduction treatment and allogeneic stem cell transplantation (SCT) in second complete remission (CR) in Sweden 2003-2007.

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.

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.

The primary goal of this study is to provide comprehensive and objective information on impairments of musculoskeletal health, sensory function, and fitness among a large group of childhood ALL survivors, and to define high risk groups by assessing treatment factors that contribute to impaired function. This study includes a direct, objective evaluation of musculoskeletal function, sensory capacity, fitness, and physical activity patterns among adults who were treated for childhood ALL at St. Jude Children's Research Hospital (SJCRH) between 1980 and 1999. Among 899 ALL survivors, all of whom are eligible for an institutionally funded clinical study of medical late effects, the study will recruit 364 to participate in our evaluations. The study will also recruit 364 individuals for a comparison group, frequency matching on race/ethnicity, age and gender.

Evaluation of safety profile and tolerability of MabThera (rituximab) in combination with chemotherapy (fludarabine and cyclophosphamide) in the treatment of Chronic Lymphocytic Leukemia (CLL).

This study is intended for Chronic Lymphocytic Leukemia patients who have already undergone a first or second treatment with drugs named bendamustine and rituximab. It will observe the results of this treatment and evaluate its efficacy and side effects.
