Cancer of the oropharynx in the province of Bergamo. A descriptive study

Backgrounds and aims. The authors analyse the trend of death caused by cancer of the oropharynx from 1988 to 1994 in the Province of Bergamo, a zone with a high prevalence for numerous tumours. Data on mortality were provided by the Health services for the individual Local Health Authorities around Bergamo.
Methods. Data were processed using statistical methods which enabled a descriptive evaluation of the phenomenon (absolute number, raw rates, specific annual rates for sex and age, etc.). Indirect standardisation was performed using the specific rates for age and sex in Italy for the period 1988-1993 as a reference standard. The mortality rates of the individual Local Health Authorities were also compared in order to evaluate possible territorial differences.
Results. The following points emerge from this study: the number of deaths from cancer of the oropharynx in the area around Bergamo is higher than the expected national level; this pathology predominantly affects males and is most frequently manifested in elderly subjects; the areas to the west (for males) and north (for females) of Bergamo show the highest frequency of oropharyngeal cancer; the trend of mortality rates during the period in question appears to fall in males and is stationary in females.
Conclusion. In conclusion, this descriptive study does not suggest any etiopathogenetic hypotheses. Further studies are now required to identify the role played by individual and/or environmental risk factors.
