The NCCN Guidelines for Head and Neck Cancers address tumors arising in the oral cavity (including mucosal lip), pharynx, larynx, and paranasal sinuses, as well as occult primary cancer, salivary gland cancer, and mucosal melanoma (MM). The specific site of disease, stage, and pathologic findings guide treatment (eg, the appropriate surgical procedure, radiation targets, dose and fractionation of radiation, indications for systemic therapy). The NCCN Head and Neck Cancers Panel meets at least annually to review comments from reviewers within their institutions, examine relevant new data from publications and abstracts, and reevaluate and update their recommendations. These NCCN Guidelines Insights summarize the panel’s most recent recommendations regarding management of nasopharynx cancer and ongoing research in this area.

Objectives/HypothesisHuman papillomavirus (HPV)‐positive and HPV‐negative oropharyngeal squamous cell carcinoma (OPSCC) are distinct disease entities. Prognostic factors specific to each entity have not been adequately explored. Goals for this study were: 1) to determine whether HPV‐positive and HPV‐negative OPSCCs have distinct prognostic factors, and 2) to explore the prognostic significance of sex and race in OPSCC after HPV stratificationStudy DesignRetrospective case series.MethodsA retrospective review of 239 incident OPSCC patients from 1995 to 2012, treated at Johns Hopkins and University of California–San Francisco was conducted. Women and nonwhite races were oversampled. All analyses were stratified by tumor HPV in situ hybridization status. The effects of sex and race on survival were considered in Kaplan‐Meier and unadjusted and adjusted Cox regression models.ResultsOne hundred thirty‐four (56.1%) OPSCC patients were HPV positive. On univariate analysis, women had better overall survival than men among HPV‐positive (hazard ratio [HR]: 0.47, 95% confidence interval [CI]: 0.20‐1.07; P = .06) but not HPV‐negative (HR: 0.73, 95% CI: 0.43‐1.24; P = .24) OPSCCs. On multivariate analysis, women with HPV‐positive OPSCCs remained at lower risk of death (adjusted hazard ratio [aHR]: 0.34, 95% CI: 0.12‐0.96; P = .04). Survival did not vary significantly by race among HPV‐positive patients. Among HPV‐negative patients, Hispanic patients had significantly better survival in unadjusted (HR: 0.27, 95% CI: 0.08‐0.91; P = .04) but not adjusted (aHR: 0.93, 95% CI: 0.11‐7.36; P = .94) analysis.ConclusionsWomen with HPV‐positive OPSCC may have improved overall survival compared to men. Sex does not play a prognostic role in HPV‐negative OPSCC. There are no differences in prognosis by race among HPV‐positive or HPV‐negative patients.Level of Evidence4 Laryngoscope, E288–E296, 2018
