Objectives:
Incidence rates for human papillomavirus positive oropharyngeal cancer (HPV-positive OPC) have significantly increased in numerous developed countries in recent decades. Fortunately, HPV-positive OPC has improved survival relative to HPV-negative OPC. Given these incidence trends and survival differences, we hypothesized that OPC survivorship has increased in affected populations over time.
Materials And Methods:
Poisson and Cox regression models were used to examine incidence and OPC survivorship trends in a population-based prospective registry, the Danish Cancer Registry.
Results:
In Denmark, OPC incidence (p<0.001) and median survival (p<0.001) significantly increased from 1977 to 2012. Consequently, the number of 5-year OPC survivors in the Danish population increased from 72 in 1980 to 1311 in 2010.
Conclusions:
The long-term sequelae of curative therapy in the growing number of OPC survivors will need to be evaluated to address their unique survivorship needs.
