Projected oropharyngeal carcinoma incidence among middle-aged US men.

BACKGROUND: The incidence of oropharyngeal cancer (OPC) is rapidly increasing. This study aimed to describe the temporal trends and projection of OPC incidence. METHODS: Incidence data were obtained from the Surveillance, Epidemiology, and End Results (SEER) database and trends were calculated using the joinpoint regression model. RESULTS: The incidence of OPC in the US population significantly increased by 1.94% (95% confidence interval [CI], 1.65%-2.23%) per year from 2000 to 2015. OPC was projected to increase continuously over the next 30 years, with more than half of projected new OPC cases being found in non-Hispanic white men aged 55-69 years. By 2045, OPC will become the third most common cancer in 55-69-year-old non-Hispanic white men in the United States. CONCLUSIONS: The incidence of OPC is expected to increase substantially in the US population, particularly among middle-aged non-Hispanic white men. Our projections may have implications for policy makers.
