BACKGROUNDHuman papillomavirus (HPV) vaccines can potentially prevent greater than 90% of cervical and anal cancers as well as a substantial proportion of vulvar, vaginal, penile, and oropharyngeal cancers caused by certain HPV types. Because more than 38,000 HPV-associated cancers are diagnosed annually in the United States, current studies are needed to understand how relative survival varies for each of these cancers by certain demographic characteristics, such as race and age.METHODSThe authors examined high-quality data from 27 population-based cancer registries covering approximately 59% of the US population. The analyses were limited to invasive cancers that were diagnosed during 2001 through 2011 and followed through 2011 and met specified histologic criteria for HPV-associated cancers. Five-year relative survival was calculated from diagnosis until death for these cancers by age, race, and sex.RESULTSThe 5-year age-standardized relative survival rate was 64.2% for cervical carcinomas, 52.8% for vaginal squamous cell carcinomas (SCCs), 66% for vulvar SCCs, 47.4% for penile SCCs, 65.9% for anal SCCs, 56.2% for rectal SCCs, and 51.2% for oropharyngeal SCCs. Five-year relative survival was consistently higher among white patients compared with black patients for all HPV-associated cancers across all age groups; the greatest differences by race were observed for oropharyngeal SCCs among those aged
