Yin LX , et al. - Authors aimed to determine if human papillomavirus (HPV)-positive and HPV-negative oropharyngeal squamous cell carcinoma (OPSCC) had distinct prognostic factors. They also explored the prognostic significance of sex and race in OPSCC after HPV stratification. Improved overall survival could be noted in women vs men. In HPV-negative OPSCC, sex was not seen to play a prognostic role. Among HPV-positive or HPV-negative patients, no differences in prognosis by race were seen.
