In 2005, an estimated 29,370 newcases of oral cavity and pharyngealcancers were diagnosed inthe United States, accounting for2.14% of all cancer cases.[1] Over7,000 individuals will die from thesecancers in this country in 2005-approximately one death per hour.Many advances have been made inthe diagnosis and treatment of thesecancers, yet the mortality rate remainshigh (5-year survival rate of ~50%).Probably the most important approachis early detection, since early-stagetumors are associated with markedlybetter survival rates than late-stagecancers that have already spread toregional tissues and lymphatics.
