Ethics approval and consent to participate
: This is an IRB-approved (University of Cincinnati IRB#: 2016–0532) retrospective study and included adult patients with HPV-associated OPSCC that underwent definitive surgical resection and are followed at the University of Cincinnati and consented to have their tissue stored in University of Cincinnati’s Head and Neck Cancer biorepository. As it was a retrospective study and consent had been previously obtained to store each patient’s tissue in our biorepository for research purposes, the need for new consents for this particular study was waived.
: As data in the manuscript was presented in aggregate, this requirement does not apply to our study.
: The authors declare that they have no competing interests.
