Background: The relationship between bladder cancer and some environmental contaminants, cigarette smoke and occupational exposure has already been known for a long time. The territorial analysis of the mortality due to this cancer typology singles out different areas in which it is possible to identify a major environmental or exposure pressure, considering the existence of some historically industrialized provinces. Methods: This study employs a methodology based on a direct standardization by age based on the average number of deaths of the 5 years for bladder cancer in all the 103 Italian provinces, considering the population divided by sex. The standardized mortality rate obtained by single provinces has been related to the national average rate in order to have the measure of the risk of death for this cancer. Then, linear regression methodology has been applied to the standardized mortality rates. Results: An unexpected high mortality rate has been pointed out in the province of Neaples (24.8/100,000 inhabitants compared to a national rate of 14.4/100,000) and higher than other provinces historically industrialized such as Turin (18.2/100,000). Moreover, concerning male's population, there is a considerable turnabout of the general mortality gap north-south with a disadvantage for the southern part of Italy; on the contrary, females seem to present a gap directly proportional to the industrialized level of the Italian provinces. The linear regression shows a generallly stable situation excluding Sardinia region, where an increased number of cases is registered for male population in the five years considered. Conclusions: The case of the province of Neaples is probably related to an inadequate disposal of city solid wastes and to the presence of rubbish dumps in areas with hydrogeological faults, and a consequent environmental contamination. The Neaples province is not an historically industrialized area like Turin. The mortality of the Sardinia region has been associated by some researchers to the strong presence of military bases like the USA submarines harbour at the Maddalena island.

Abstract
Background: The relationship between bladder cancer and some environmental contaminants, cigarette smoke and occupational exposure has already been known for a long time. The territorial analysis of the mortality due to this cancer typology singles out different areas in which it is possible to identify a major environmental or exposure pressure, considering the existence of some historically industrialized provinces. Methods: This study employs a methodology based on a direct standardization by age based on the average number of deaths of the 5 years for bladder cancer in all the 103 Italian provinces, considering the population divided by sex. The standardized mortality rate obtained by single provinces has been related to the national average rate in order to have the measure of the risk of death for this cancer. Then, linear regression methodology has been applied to the standardized mortality rates. Results: An unexpected high mortality rate has been pointed out in the province of Neaples (24.8/100,000 inhabitants compared to a national rate of 14.4/100,000) and higher than other provinces historically industrialized such as Turin (18.2/100,000). Moreover, concerning male's population, there is a considerable turnabout of the general mortality gap north-south with a disadvantage for the southern part of Italy; on the contrary, females seem to present a gap directly proportional to the industrialized level of the Italian provinces. The linear regression shows a generallly stable situation excluding Sardinia region, where an increased number of cases is registered for male population in the five years considered. Conclusions: The case of the province of Neaples is probably related to an inadequate disposal of city solid wastes and to the presence of rubbish dumps in areas with hydrogeological faults, and a consequent environmental contamination. The Neaples province is not an historically industrialized area like Turin. The mortality of the Sardinia region has been associated by some researchers to the strong presence of military bases like the USA submarines harbour at the Maddalena island.File | Dimensione | Formato | |
