Study Description

Brief Summary: 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.

Detailed Description: This study is a prospective, multicenter study on patients with a diagnosis of NHL, MM or CLL. All the patients with a diagnosis of NHL, MM or CLL in the participant centers will be purposed to participate. Each patient included will have an interview with a clinical study technician or doctor of occupational medicine. A specific detailed questionnaire has been created for the study. It focuses on specialized professional careers to spread occupational exposures to nuisances (substances and agents) suspected of being associated with NHL, MM or LLC risk. Each questionnaire will be evaluated by a physician expert in occupational disease, to conclude on the parameters exposure to the various suspected carcinogens. The study will cover 300 patients.
