[SENTIERI-ReNaM: Rationale and objectives]

The purpose of the SENTIERI-ReNaM Project is to analyse the incidence of mesothelioma in Italian National Priority Contaminated Sites (NPCSs) in order to estimate the health impact of asbestos on resident populations, disentangling the role of occupational and environmental exposures. SENTIERI Project has provided the relevant information on geographic and demographic structure of NPCSs and on existing sources of contamination. The Italian National Mesothelioma Registry (ReNaM), that covers the whole country through its Regional Operational Centres (CORs), has made available the procedures for estimating the incidence of mesothelioma in NPCSs and for assessing occupational and environmental asbestos exposure of the individual cases. The synergy between these two epidemiological surveillance systems lay also the ground for communication programmes with the affected communities.
