title: Demographics and occurrence of oral and pharyngeal cancers. The outcomes, the trends, the challenge.
abstract: BACKGROUND
  This article summarizes current trends in the occurrence of, mortality rates associated with and rates of survival of oral and pharyngeal cancer.
  
  
  METHODS
  The author reviewed relevant data and literature on these aspects of oral and pharyngeal cancer, including data from the National Cancer Institute's Surveillance, Epidemiology and End Results program collected from 1973 to 1998.
  
  
  RESULTS
  The occurrence of oral and pharyngeal cancer in the United States remains constant, at about 30,000 new cases diagnosed each year. There has been no marked improvement in the five-year survival rates, which remain at about 50 percent, despite advances in surgery and radiation. Detection of early, localized lesions has not improved significantly during the past three decades. There is a minor trend toward a younger age at diagnosis and a slight increase among women.
  
  
  CONCLUSIONS
  On the basis of epidemiologic data, it appears that the most important approach to decreasing morbidity and mortality associated with oral cancer is increasing early detection of localized lesions combined with appropriate treatment. Concomitantly, aggressive counseling is vital to prevent use and encourage cessation of tobacco and alcohol use.
  
  
  CONCLUSIONS
  Professional and public education about oral and pharyngeal cancer needs to be improved, and clinicians must emphasize the need for and perform routine oral cancer examinations to promote early diagnosis and treatment.
