Abstract:
This is a descriptive epidemiological study of head and neck malignancies in Tarragona province (609,673 inhabitants in 2001). Data of population-based incidence, mortality, survival and prevalence, were analyzed concerning 3,507 head and neck malignancies recorded in the Tarragona Cancer Registry during the period 1980 to 2005 (609 lip cancer, 410 tongue, 374 oral cavity, 142 salivary glands, 140 tonsil, 118 nasopharyngeal, 239 hypopharyngeal, 122 others of oral cavity and pharynx, 87 nasal cavities and sinus and 1,266 laryngeal cancer). The methodology of population-based cancer registries has been applied, following the criteria of the International Agency for Research on Cancer (IARC), in order to ensure both completeness and accuracy of data. Evaluation of the standard quality indices showed that they were appropriate for the anatomical sites studied, both individually and collectively. The temporal trend in incidence has been studied and its projection to 2010 and 2015 estimated. Results are referred by total head and neck and by one out of every ten localizations. It is emphasized that the age-adjusted incidence rate of laryngeal cancer in men is one of the highest in the world. International comparisons of the incidence and survival have been made. The survival rate has remained stable, and is similar to the rest of Europe The main conclusions are that the head and neck malignancies in Tarragona show a westernized epidemiological pattern, similar to Southern Europe. There is an overall reduction in the time trend of incidence in men, correlated with the reduction in tobacco consumption. The increasing trend in sites such as tonsil, has been correlated with the exposure to human papilloma virus. As in the rest of Europe, improvements in population-based relative
