[Scientific collaboration between Istituto Superiore di Sanità and Italian Association of Cancer Registries for the study of cancer incidence in Italian polluted sites].

The collaborative study between Istituto superiore di sanità and Associazione italiana registri tumori (ISS-AIRTUM) aims at investigating cancer incidence in polluted sites for adults and for children (0-14 years) and adolescents (15-19 years) to comment the study results in the light of a set of a priori hypotheses. On the whole, 141 out of 298 municipalities included in SENTIERI Project are served by a Cancer Register participating to the AIRTUM network. For a description of SENTIERI, refer to the 2010 Supplement of Epidemiology & Prevention devoted to SENTIERI Project. The time window of the study is the period 1996-2005. The number of expected cases in each polluted site will be estimated by applying incidence rates of the national pool of cancer registries and of the pool of the geographic macroarea in which each site is located: Northern, Central, Southern Italy and Islands. Cancer incidence in children and adolescents is one of the main priorities of international public health institutions, because of the need to protect childhood health from involuntary exposure to environmental risk factors. Standardized incidence ratios (SIRs) will be computed using expected figures derived from the national pool of cancer registries.
