[All-cause mortality from 1970 to 2013 in the municipality of Trino (Piedmont region, Italy), previously home to a nuclear plant]

Mortality studies conducted to date in the area of Trino (Piedmont Region, northern Italy) have been limited to the years from 2000 onwards. These studies have highlighted an increased frequency of brain tumors, leukemia, mesothelioma, peritoneal, prostate, larynx and total tumors in men in the municipality of Trino while for women the increased risk was limited to melanoma. The present study has allowed us to make more robust epidemiological considerations and to analyze the historical trend in mortality in the municipality (starting from 1970) correlating it also to the social and economic changes reported. We calculated the Standard Mortality Ratio (indirect standardization) by retrieving data on observed cases from the years 1980 to 2013 from the Italian national statistics bureau (ISTAT) and the municipal archives, and using regional specific mortality rates in the Piedmont region from 1980 to 2013 for expected cases. Results show a slowly decreasing trend for brain tumors in the last 10-15 years while for leukemia, we observe a sharp increase in the same time period, affecting both men and women indistinctly.
