Epidemiology of Oral-Cavity and Oropharyngeal Carcinomas Controlling a Tobacco Epidemic While a Human Papillomavirus Epidemic Emerges

Although tobacco prevalence is declining in most developed countries, less developed countries are still experiencing an increase in tobacco use. Thus the future burden of oral-cavity and oropharyngeal cancers in less developed countries is expected to be heavy. The incidence of human papillomavirus (HPV)-associated oropharyngeal cancer is dramatically increasing in the United States and other developed countries, although trends in less developed countries are not clear at present. HPV vaccine compliance in the United States is low, although it continues to increase each year. Increasing the HPV vaccination rate to control future HPV-associated cancer incidence remains a priority.
