RESUMO

Introduction: Upper Aerodigestive Tract Cancer comprises a group of neoplasms which spread over many anatomic regions. Considering most of the locations, the worst risk coefficients are tobacco and alcohol. Taken the coefficients are known, prevention and precocious detection campaigns are expected to lessen the incidence statistics. Objectives. To estimate the trends on lip, oral cavity (tongue and mouth), salivary gland, oropharyngeal, nasopharyngeal and hypopharyngeal cancer incidences in some locations worldwide between 1969 - 1999. Methods Incidence coefficient data of eighteen records from the Population Database Cancer Registry which had its history published in “Cancer Incidence in Five Continents” has been analysed applying polynomial regression models. Results There has been a statistically significant increase to the number of oral cavity cancer in Sao Paulo among women; in European countries as well as in some North American cities, the increase was detected among both men and women. On the other hand, there has been a decrease in Puerto Rico, Mumbai and Singapore. The incidence of lip cancer decreased in most locations (among men). However, an increase has been detected in North Europe and in Iowa, USA (among women). Oropharyngeal cancer has increased in number among men in Europe and Iowa, USA; it decreased in number in Cali, Quebec, and other areas in Ásia. Hypopharyngeal cancer has shown to be an increasing trend in many Europeans countries among men, but a decreasing one in Sweden, England, Singapore and Puerto Rico. Conclusion Oral cavity and oropharyngeal neoplasms trends proceed grow in many locations. Finally, the need for prevention and precocious detection campaigns is urgent.
