The prognostic role of sex, race, and human papillomavirus in oropharyngeal and nonoropharyngeal head and neck squamous cell cancer

TLDR
Survival differences were explored by the tumor HPV status among patients with OPSCCs by sex and race and patients with nonoropharyngeal (non‐OP) head and neck squamous cell cancers (HNSCCs).
Abstract
BACKGROUND Human papillomavirus (HPV) is a well-established prognostic marker for oropharyngeal squamous cell cancer (OPSCC). Because of the limited numbers of women and nonwhites in studies to date, sex and racial/ethnic differences in prognosis have not been well explored. In this study, survival differences were explored by the tumor HPV status among 1) patients with OPSCCs by sex and race and 2) patients with nonoropharyngeal (non-OP) head and neck squamous cell cancers (HNSCCs). METHODS This retrospective, multi-institution study included OPSCCs and non-OP HNSCCs of the oral cavity, larynx, and nasopharynx diagnosed from 1995 to 2012. Race/ethnicity was categorized as white non-Hispanic, black non-Hispanic, Asian non-Hispanic, and Hispanic of any race. Tumors were centrally tested for p16 overexpression and the presence of HPV by HPV16 DNA and high-risk HPV E6/E7 messenger RNA in situ hybridization. Kaplan-Meier and Cox proportional hazards models were used to evaluate overall survival (OS). RESULTS The study population included 239 patients with OPSCC and 621 patients with non-OP HNSCC with a median follow-up time of 3.5 years. After adjustments for the tumor HPV status, age, current tobacco use, and stage, the risk of death was lower for women versus men with OPSCC (adjusted hazard ratio, 0.55; P = .04). The results were similar with p16. In contrast, for non-OP HNSCCs, HPV positivity, p16 positivity, and sex were not associated with OS. CONCLUSIONS For OPSCC, there are differences in survival by sex, even after the tumor HPV status has been taken into account. For non-OP HNSCC, the HPV status and the p16 status are not of prognostic significance. Cancer 2017;123:1566–1575. © 2017 American Cancer Society.

Association of Human Papillomavirus Status at Head and Neck Carcinoma Subsites With Overall Survival.

TL;DR: Human papillomavirus positivity was associated with improved survival in 4 subsites (oropharynx, hypopharynX, oral cavity, and larynx), and the largest survival difference was noted in the oropharynx and hypopharyx subsites.

Increasing prevalence of human papillomavirus-positive oropharyngeal cancers among older adults.

TL;DR: The incidence of oropharyngeal squamous cell carcinoma (OPSCC) is increasing among older adults and it is unknown whether these trends can be explained by human papillomavirus (HPV) and whether HPV‐related tumors remain associated with an improved prognosis among older patients.

Sex Disparities in Cancer Mortality and Survival

TL;DR: Male-to-female MRRs differed markedly while cancer survival disparities were much less pronounced, suggesting that sex-related cancer disparities are more strongly related to etiology than prognosis.

Detection of transcriptionally active high risk HPV in patients with head and neck squamous cell carcinoma as visualized by a novel E6/E7 mRNA in situ hybridization method

TL;DR: Testing for HPV E6/E7 transcripts by RNA ISH is ideal because it confirms the presence of integrated and transcriptionally active virus, permits visualization of viral transcripts in tissues, and is technically feasible for routine testing in the clinical laboratory.

Racial Survival Disparity in Head and Neck Cancer Results from Low Prevalence of Human Papillomavirus Infection in Black Oropharyngeal Cancer Patients

TL;DR: Worse OS for black SCCHN patients was driven by oropharyngeal cancer outcomes, and that for black oroph throat cancer patients by a lower prevalence of HPV infection, which has important implications for the etiology, prevention, prognosis, and treatment ofSCCHN.
