[Herbicides and neoplasms of the hemolymphopoietic system]

The study is a population-based case-control study on hematolymphopoietic tumors, conducted in west Liguria with high prevalence of exposure to chemicals suspected (about 10%) of increasing the risk of leukaemias or lymphomas and multiple myeloma (pesticides). Cases and control were identified and confirmed during the period 1/1/1990 through 31/12/1993. Cases are identified through periodic contacts with the Pathology, or Hematology or other relevant Department of the Hospitals of west Liguria and Genoa town or University of Genoa where patients living in these area are referred for hematolymphopoietic malignancies. Controls are a random sample of the general population living in each area (using the demographic health archives). The range of the age is 20-74. After identification each case or control is contacted to have his consent to the interview near the home. Informations collected using a most completed questionnaire regard drinking and smoking habit, the addresses and the conditions of the homes where spending the life, particularly hobbies about exposure of pesticides and/or solvents, more important pathological events on the life and the occupational exposure. Actually we are in the phase of identification of cases and controls.
