This cross-sectional study examines the rate of HPV vaccination and the number eligible for this vaccination among younger veterans and civilians.

Disparities in head and neck cancer incidence and trends by race/ethnicity and sex.

BACKGROUND: The epidemiology of head and neck cancer (HNC) sites differ substantially. This study compares HNC incidence trends by site and demographic subgroups. METHODS: We used the U.S. Cancer Statistics Public Use Database to calculate HNC incidence rates per 100 000. We assessed trends with annual percent change (APC) longitudinally from 2001 to 2017. RESULTS: The oropharyngeal cancer incidence APC decreased from 4.38% (95% CI: 3.6, 5.1) to 2.93% (2.5, 3.3) in 2008 among White males. Oral cavity cancer incidence rose in Other race males (APC 2.5% [1.6, 3.36]) and White females (APC: 0.96% [0.7, 1.2]). Although decreasing (APC: -1.15% [-1.48, -0.83]), laryngeal cancer incidence remained disproportionately high among Black males. CONCLUSIONS: Notable incidence trends occurred in non-White groups at non-oropharyngeal sites. With parity of smoking rates by race, differing sexual behaviors, and shifting demographics by race and sex, future studies of HNC trends should consider stratifying analyses to understand health disparities.

No survival benefit in never-smoker never-drinker patients with oral cavity cancer.

BACKGROUND: Although strongly associated with tobacco and alcohol use, many oral cavity squamous cell carcinoma (OCSCC) cases occur in patients without exposure to either, known as "never-smoker, never-drinkers" (NSND). We aimed to compare clinical outcomes between NSND and tobacco/alcohol-exposed populations and to define demographic characteristics of NSND. METHODS: We performed a retrospective, single-institution cohort study of 672 OCSCC patients. Cox models were used to estimate differences in overall survival (OS) and recurrence-free survival (RFS) between NSND and tobacco/alcohol-exposed patients while adjusting for confounders. RESULTS: NSND represented 25.6% of our cohort and were older, more female, and more economically advantaged. Among NSND, oral tongue tumors dominated in younger patients, while alveolar ridge tumors dominated in elderly patients. Multivariate survival analysis revealed no differences in OS or RFS between NSND and tobacco/alcohol-exposed patients. CONCLUSION: When adjusted for independent biologic features, clinical outcomes in OCSCC are similar between NSND and tobacco/alcohol-exposed patients.

Quantifying Total and Out-of-Pocket Costs Associated With Head and Neck Cancer Survivorship.

Importance: Oncologic treatment is costly to the health care system and to individuals, but patients with head and neck cancer (HNC) also have long-term care needs after treatment. Survivors of HNC require specific consideration given their rapidly growing numbers. This subpopulation of cancer survivors often experiences long-term treatment-associated morbidity. Objective: To describe the total and out-of-pocket (OOP) costs associated with HNC survivorship and the risk factors for financial toxicity among this population. Design, Setting, and Participants: This was a retrospective review and economic evaluation of a cohort of US adults with a diagnosis of HNC from 2006 to 2018. The study used data the from IBM MarketScan Commercial Claims Database. Data were analyzed from November 2020 to June 2022. Exposures: Treatment for HNC. Main Outcomes and Measures: Total and OOP medical costs were assessed monthly and reported relative to the date of HNC diagnosis. The primary outcome was the difference between a patient's mean monthly survivorship costs (13-60 months after diagnosis) and mean monthly baseline costs (7-12 months before diagnosis). Univariate and multivariable linear regression models were created for total and OOP costs to generate coefficient estimates with 95% CIs. Results: The study cohort of this economic evaluation included 19 098 patients with HNC (median [range] age, 56 [18-64] years; 14 144 [74.1%] men and 4954 [25.9%] women; race and ethnicity were not considered). Throughout the survivorship period, median total and OOP costs were $372 per month and $31 per month higher than baseline costs, respectively, with variation in expenses by demographic information, health plan type, and oncologic variables. In the multivariable model, greater total and OOP excess survivorship costs were associated with female sex ($343/mo; 95% CI, $126 to $560 and $9/mo; 95% CI, $4 to $14). Highest and lowest total excess survivorship costs associated with cancer site were seen for hypopharyngeal ($1908/mo; 95% CI, $1102 to $2714) and oropharyngeal cancers (-$703/mo; 95% CI, -$967 to -$439) vs oral cavity cancers. Compared with surgery or radiation therapy alone, multimodal treatment was generally associated with excess OOP survivorship costs. Conclusions and Relevance: The findings of this retrospective economic evaluation review suggest that the costs of HNC survivorship remain persistently elevated above baseline costs for at least 5 years after diagnosis. High survivorship costs were associated with female sex, hypopharyngeal tumors, and treatment with multimodal therapy. Practitioners should seek to minimize costs for these patients at higher-risk of financial toxicity after treatment and work to provide directed supportive services.

Temporal trends in oropharyngeal cancer incidence, survival, and cancer-directed surgery among elderly Americans.

OBJECTIVE: This study assesses longitudinal epidemiologic trends in the oldest head and neck cancer (HNC) patients, comparing the oropharynx to other mucosal HNC sites. MATERIALS AND METHODS: Using data from the Surveillance, Epidemiology, and End Results database, trends in incidence, two-year cancer specific mortality, and percent of cases recommended for and which received surgery from 2000 to 2018 in patients ages ≥85 years were assessed using Joinpoint analysis by HNC site. Trends were quantified as annual percentage change (APC) with 95% confidence intervals (CI). RESULTS: Among older adults, oropharyngeal cancer (OPC) incidence increased (APC = 1.80% [95% CI: 0.94-2.67]), while mortality decreased (APC = -2.01% [95% CI: -3.26--0.74]) from 2000 to 2018. At other mucosal HNC sites, incidence and mortality remained stable. Percentage of patients who received surgery significantly changed for oropharyngeal (APC = -15.34% from 2000 to 2005 [95% CI: -24.37 to -4.79]) and laryngeal (APC = -4.61% from 2000 to 2008 [95% CI -8.28 to -0.80]) cancers. Trends in recommendation for surgery varied by site with significant decreases at the larynx, oral cavity, and oropharynx. CONCLUSION: OPC incidence is increasing among the oldest HNC patients. An increasing proportion of HPV-associated tumors could account for associated mortality improvement. There has been a shift towards non-surgical therapy possibly due to known favorable response of HPV-associated OPC to radiation therapy and/or poor surgical candidacy in this age group. The evolving treatment approach has not been detrimental to population-level survival outcomes, but optimal treatment has yet to be established. Future studies with pathologically confirmed HPV status are needed to better understand older adult OPC burden.

Frontal Balloon Sinuplasty in Complicated Acute Pediatric Rhinosinusitis (ARS).

Utilization of frontal balloon sinuplasty in pediatric complicated acute rhinosinusitis (ARS) is demonstrated to be a safe and expedient alternative to other procedures such as trephination or functional endoscopic sinus surgery (FESS) in this case series. We performed a retrospective review of six pediatric cases of frontal balloon sinuplasty for ARS with intracranial complications at a tertiary academic center. Patients underwent unilateral (n = 5) or bilateral dilation (n = 1) in addition to functional endoscopic sinus surgery (FESS) including anterior ethmoidectomy (n = 5) and maxillary antrostomy (n = 6). This technique effectively addressed frontal sinus obstruction and served as an alternative to procedures such as trephination or functional endoscopic sinus surgery. No immediate or short-term complications of balloon dilation were observed in these cases. A larger cohort and extended follow-up are necessary to determine the use and long-term impact of this technique.

20 pack-year smoking history as strongest smoking metric predictive of HPV-positive oropharyngeal cancer outcomes.

OBJECTIVES: While smoking is associated with worse outcomes in HPV-positive oropharyngeal squamous cell carcinoma (OPSCC), the magnitude of this association is unclear given the heterogenous smoking definitions and outcomes. Our objective was to investigate the association between smoking, survival, and recurrence in HPV-related OPSCC using multiple smoking metrics reported in the literature. MATERIALS AND METHODS: This was a retrospective cohort study of 375 adults with p16+ OPSCC undergoing surgical resection (n = 272) or definitive chemoradiation (n = 103) at a tertiary academic institution from 2006 to 2017. The primary outcome was overall survival (OS). Secondary outcomes included disease-free survival (DFS), disease-specific survival (DSS), and recurrence. We used multiple smoking metrics commonly cited in previous studies, including ever versus never smokers, current versus former/never smokers, ≤10 versus >10 pack-year, ≤20 versus >20 pack-year, and continuous pack-year. RESULTS: There were 375 patients, median age 58 years, with 326 (87%) males, and median follow-up of 52 months. Of all smoking metrics, >20 pack-year history was the strongest predictor of both OS (HR 2.24, 95% CI: 1.19-4.20) and DFS (HR 1.67, 95% CI: 1.04-2.66) on univariable and multivariable analysis after adjusting for age, overall stage, and comorbidities. Patients with >20 pack-year smoking history were also more likely to have recurrence (HR 1.59, 95% CI: 0.95-2.67) after adjusting for overall stage. CONCLUSION: Heavier smoking >20 pack-years was the strongest smoking metric associated with 2-times worse survival and recurrence. Our findings suggest that >20 pack-year smoking history may be a more useful cutoff for risk stratification models but requires further validation.

Prognostic Significance of Smoking in Human Papillomavirus-Positive Oropharyngeal Cancer Under American Joint Committee on Cancer Eighth Edition Stage.

OBJECTIVE: To determine the prognostic significance of smoking in human papillomavirus (HPV)-positive oropharyngeal squamous cell carcinoma (OPSCC) when considering American Joint Committee on Cancer eighth edition (AJCC-8) stage. STUDY DESIGN: Retrospective cohort study. METHODS: Three hundred seventeen HPV-positive OPSCC patients with known AJCC-8 stage and smoking status (<10 or ≥10 pack-years) seen at a tertiary center from 1997 to 2017 were studied. We used the Kaplan-Meier method to compare 5-year overall survival (OS) by smoking status and by clinical AJCC-8 stage and smoking status combined. Hazard ratios (HRs) were estimated with Cox proportional hazard regression for the independent effects of smoking and AJCC-8 stage. We also studied pathologic stage and estimated the combined effects of smoking and clinical stage. RESULTS: The ≥10 pack-years smokers had worse 5-year OS than <10 pack-years smokers (93.6%; 95% confidence interval (CI): 89.7-97.8 vs. 82.3%; 95% CI: 76.0%-89.1%). When stratified by AJCC-8 clinical stage, only stage I <10 pack-years smokers (98.7%; 95% CI: 96.3%-100.0%) had significantly better 5-year OS than their ≥10 pack-years (84.8%; 95% CI: 76.4%-94.1%) counterparts. In a multivariable analysis, ≥10 pack-years smoking was associated with increased hazard of death when adjusting for AJCC-8 clinical (HR: 2.52; 95% CI: 1.16-5.46) and pathologic (HR: 5.21; 95% CI: 1.47-18.5) stage. In both analyses, stage III patients demonstrated worse survival than stage I, and smoking had greater impact at lower stages. CONCLUSIONS: Smoking is a negative prognosticator in HPV-positive OPSCC and interacts with AJCC-8 clinical stage. It is important to understand the impact of smoking in HPV-positive disease when considering treatment plans and deintensification trials. LEVEL OF EVIDENCE: 2b Laryngoscope, 130: 1961-1966, 2020.
