Introduction There is currently a lack of available data clearly addressing whether the proportion of young patients diagnosed with head and neck cancer (HNC) within the U.S. has increased over the last several decades in comparison to other age cohorts. This study attempts to elucidate any trends in oral cavity, oropharynx, larynx and hypopharynx cancer age distribution in the United States population from 1975-2016. Unlike previous studies, this paper does not track incidence, but rather reports proportional changes of prevalence within age cohorts over time. Methods This is a retrospective chart review centered on data from the Surveillance, Epidemiology, and End Results (SEER) Program of the National Cancer Institute (NCI). Each decade interval from 1975-2016 displays the proportion of HNC patients, classified by primary tumor subsite, within each age cohort. Results Mean age at diagnosis increased for three of the four HNC evaluated. Oropharyngeal cancer was the only subsite to demonstrate an overall proportional increase, mainly in middle age (40-59 years) patients. Cancers of the oral cavity were the only subset to show a true increase in the proportion of young (0-39 years) patients. When stratifying by gender, the proportion of young patients in female HNC cases is higher than the proportion of young male HNC cases. Conclusion Overall, this study demonstrates an increased proportion of older HNC patients that is consistent with the aging population. Oral cavity is the only cancer to demonstrate a true increase in the proportion of young patients, likely from the increased incidence of young women diagnosed with this cancer. Case reports citing more young patients becoming diagnosed with other types of HNC are not currently supported by the data. Lastly, the increased proportion of middle-age patients with oropharyngeal cancer likely reflects the increase in HPV-related cancers.
