Active clinical trials for "Leukemia, Lymphocytic, Chronic, B-Cell"

Lymphoid hemopathies are a group of malignant haematological disorders characterized by clonal proliferation of cells of the lymphoid line. Non-Hodgkin's lymphoma (NHL), chronic lymphocytic leukemia (CLL), and multiple myeloma (MM) are the most frequently encountered features of lymphoid hemopathies. Duriong the last 35 years the prevalence of these pathologies has increased in France but also in most industrialized countries. This increased can't be solely explained by demographic changes and improvements in diagnostic techniques. As a result, the involvement of environmental and professional factors is strongly suspected. Studies have shown that these diseases are associated with some professions or type of activity, including agricultural occupations, and other sectors such as agriculture, printing, woodworking. Some organic solvents and pesticides have been suspected of being risk factors of hematologic malignancies. Based on cohort studies and case-control studies, some of them have been identified by the International Cancer Research Center as associated with the occurrence of NHL with a sufficient or limited level of evidence. One of the difficulties encountered in the analysis of the literature has been the permanent evolution of the international classification of lymphoid hemopathies over the past 30 years. The old epidemiological studies are therefore difficult to interpret. Lymphoid hemopathies cover a range of different conditions, thus it is likely that carcinogens involved vary according to the type of hemopathy. Finally, environmental and occupational exposures to various chemicals and biological agents have evolved over time. The aim of this study is firstly to develop and validate a questionnaire to identify and quantify exposures to nuisances (substances and agents) suspected of being associated with the occurrence of NHL, MM and LLC. In a second time, this questionnaire will be used as a support for the realization of a subsequent case-control study to improve epidemiological knowledge on these diseases.

300 patients, starting a new pharmacological treatment for B-CLL, were enrolled by 36 Italian Centres for assessing the Quality of Life (QoL). A descriptive analysis of QoL and the correlation of the age, sex, stage of disease, Time from first B-CLL diagnosis, Number of previous B-CLL treatments, reason of starting of the new B-CLL treatment: therapeutic Regimen, type of Centre, B-CLL treatment lasting, response to B-CLL treatment.

Magnetic nanoparticles coated with anti-EpCAM or anti-CD52 antibodies will be tested ex-vivo in patients blood .

This observational study will assess the health related quality of life (HQRL) profiles of patients with chronic lymphocytic leukaemia. Using health assessment questionnaires, data will be collected from patients currently receiving therapy and from those who have finished therapy and have undergone an assessment of treatment.

The purpose of this study is to collect a blood sample in patients with Chronic Lymphocytic Leukemia (CLL).

This research study is collecting and storing tissue samples from patients with rare or cutaneous non-Hodgkin lymphoma. Collecting and storing samples of tissue from patients with cancer to test in the laboratory may help the study of cancer in the future.

This trial studies financial difficulty in participants with chronic lymphocytic leukemia and multiple myeloma. Assessment of financial difficulty may help to better understand the financial impact of cancer and come up with ways to help participants avoid financial problems during treatment.

The Activity of Indoleamine 2,3-dioxygenase in patients with Chronic Lymphocytic Leukemia (CLL) is studied.

The study aims at developing a model for the prediction of time to first treatment in chronic lymphocytic leukemia patients presenting with asymptomatic early stage disease

This study is collecting and storing malignant, borderline malignant neoplasms, and related biological samples from young patients with cancer. Collecting and storing samples of tumor tissue, blood, and bone marrow from patients with cancer to study in the laboratory may help the study of cancer in the future.
