Abstract

© 2018 College of American Pathologists. All rights reserved. Context.-Types 16 and 18 are the most widely studied high-risk types of human papillomavirus (HPV). However, other high-risk HPV types (HPV non-16/18) also play a significant role in cervical neoplasia. Currently, screening and management algorithms separate out HPV 16/18 from all other HPV non-16/18 types. In addition, most of the previously vaccinated population has only been vaccinated for these high-risk types, so many women are still vulnerable to HPV non-16/18 infections. Objective.-To review the prevalence and role of HPV non-16/18 neoplasia and to review current surveillance, management, and vaccination strategies in view of these findings. Data Sources.-The study comprised a review of the literature. Conclusions.-Although HPV non-16/18 types are less frequently associated with cervical intraepithelial neoplasia and cancer, they are nonetheless a significant cause of disease. Further stratification of higher-risk HPV non-16/18 may be necessary to improve prevention and management, however, regional prevalence differences may make a unified approach difficult. As HPV 16/18 infections decrease owing to vaccination of at-risk women, the relative frequency of HPV non-16/18 will increase, although the latest vaccine covers several more high-risk types.
