BACKGROUND: As a legacy of the large asbestos consumption until the definitive ban in 1992, Italy is currently suffering a severe epidemic of asbestos related diseases. The aim of this paper is to describe the surveillance system for mesothelioma incidence and to provide evidences regarding the occurrence of the disease in Italy and the circumstances of asbestos exposure. METHODS: Italian National Register of Malignant Mesotheliomas (ReNaM) is a permanent surveillance system of mesothelioma incidence, with Regional Operating Centres (CORs) active in each Italian region, identifying incident malignant mesothelioma (MM) cases from health care structures. Occupational history, lifestyle habits and residential history are obtained using a standardised questionnaire, administered by a trained interviewer, to the subject or to the next of kin. Descriptive epidemiological figures, occupations involved in exposures and territorial maps of MM cases have been produced. RESULTS: At December 2016, ReNaM has collected 27,356 MM cases for the incidence period between 1993 and 2015. The modalities of exposure to asbestos have been investigated for 21,387 (78%) and an occupational exposure has been defined for around 70% of interviewed cases (14,818). Non-occupational exposure is still relevant with 4.9% and 4.4% of cases for which respectively a familial exposure (due to the cohabitation with an occupational exposed subject) and an environmental exposure (due to the residence near a contaminated site) has been detected. DISCUSSION: The epidemiological surveillance of MM incident cases, by the means of a national register for estimating the occurrence of the disease and identifying the circumstances of asbestos exposure, is a relevant tool for preventing asbestos exposure, for supporting the effectiveness of insurance system and for estimating reliable epidemiological figures.
