Active clinical trials for "Leukemia, Lymphoid"

Asparaginase is an important drug in the treatment of childhood leukemia. One of the rare but severe side effects to the treatment is thrombosis in or outside the central nervous system. The aim of this study is to investigate and describe the influence on the coagulation parameters during prolonged treatment with asparaginase. Hopefully this knowledge will help to foresee the risk of thrombosis and thus making it possible to prevent these.

Treatment of acute lymphoblastic leukemia achieves high cure rate, but is potentially neurotoxic. Long-term neurologic morbidity in survivors and its effect on function are inadequately studied. Neurologic outcomes will be assessed through an investigator administered questionnaire followed by comprehensive neurologic examination by the study neurologist.

RATIONALE: Collecting and storing samples of bone marrow and blood from patients with cancer to study in the laboratory may help doctors learn more about changes that may occur in DNA and identify biomarkers related to cancer. PURPOSE: This laboratory study is looking at lymphoblasts in young patients with high-risk acute lymphoblastic leukemia.

A retrospective chart review study of Philadelphia chromosome-negative R/R ALL patients in the US.

The study is designed as a multicenter, prospective, observational registry of CLL/SLL patients who are initiating approved oral kinase inhibitors, BCL-2 inhibitors or other approved anti-CLL therapies/regimens. The study will characterize treatment patterns and their association with patient characteristics, healthcare resource utilization, and clinical outcomes, as well as patient-reported outcome (PRO) measures.

Hyper-CVAD (a chemotherapy regimen) has shown promising results in adult T-cell Acute Lymphoblastic Leukemia (T-ALL). Patients with T-ALL diagnosis were reported to the Swedish Adult Acute Leukemia Registry between October 2002 and September 2006. Hyper-CVAD was recommended to all patients without severe comorbidity. Allogeneic stem cell transplantation was recommended for patients with high-risk disease. The aim of this population-based study was to assess the efficacy of Hyper-CVAD treatment.

RATIONALE: Studying samples of blood, tissue, and bone marrow from patients with cancer in the laboratory may help doctors identify learn more about biomarkers related to cancer. It may also help doctors to find better ways to treat cancer. PURPOSE: This research studies samples from patients with T-cell acute lymphoblastic leukemia (T-ALL).

This observational study will evaluate the safety and efficacy of rituximab in combination with chemotherapy in first- and second-line treatment of participants with cluster of differentiation 20 (CD20)-positive B-cell chronic lymphocytic leukemia. Data will be collected from eligible participants receiving rituximab according to the Summary of Product Characteristics (SPC) during 6 months of treatment.

The purpose of the study is to evaluate the overall and disease free survival of recipients who have received G-CSF mobilized stem cells from HLA matched sibling donors.

The investigators would like to propose a prospective longitudinal observational cohort study for patients who will be diagnosed and/or treated for acute lymphoblastic leukemia at Asan Medical Center, Seoul, Korea, to use the acquired data for fundamentals of other retrospective analysis.
