Used with permission of the American College of Surgeons, Chicago, Illinois. **Note 2:** p16 immunotesting is mandatory to use this staging system for HPV-associated cancer. HPV by in situ hybridization (ISH) may be done as an alternative. If a case of oropharyngeal cancer has p16+, then this chapter is used. If a case does not have p16 or HPV by ISH, then the case is staged by the p16- system.
