Histopathologic findings of HPV and p16 positive HNSCC

Abstract

HPV(+) and p16(+) are highly predictive for poorly differentiated tumors and basaloid SCCA. Additionally, HPV and p16 positivity demonstrate superior predictive value for lymph node metastasis above standard H&E histopathologic features. Although exact recommendations should be tempered by considerations of primary tumor subsite, T-stage, and depth of invasion, head and neck multidisciplinary teams should strongly consider aggressive lymph node treatment for any HPV(+) or p16(+) tumor.
