RESUMEN
IMPORTANCE: Thyroid eye disease (TED) negatively impacts quality of life. TED occurs predominantly in Graves' disease (GD). Teprotumumab improves TED but concern for hearing adverse events (AEs) has emerged. Hearing dysfunction is reported in thyroid autoimmune disease but the background prevalence in GD/TED without teprotumumab remains uncertain. OBJECTIVE: To quantify ear-related diagnostic codes/hearing AEs in GD, TED, and patients receiving teprotumumab by examining medical claims and clinical trials. DESIGN AND PARTICIPANTS: Deidentified claims for ear/labyrinth-related ICD-10 codes (KOMODO®) were examined in GD patients without TED, and TED patients without/with teprotumumab treatment. Hearing AE incidence/severity was evaluated in teprotumumab clinical trials. Graves' Ophthalmopathy QOL (GO-QOL) scores were compared in teprotumumab TED trial patients without/with hearing AEs. RESULTS: GD (469,720), TED (38,566) and teprotumumab-treated (967) patients were identified in the claims database. Ear-related codes (including those not specific for hearing) occurred in 24% GD, 33% TED, and 32% teprotumumab-treated patients. "Sensorineural hearing loss bilateral" was most frequent: 32,961/469,720 (7%) GD, 4,279/38,566 (11.1%) TED, and 104/967 (10.8%) teprotumumab patients. Pre-teprotumumab use,165 (17.1%) patients had ear-related codes while 98 (10.1%) had new ear-related codes post-treatment.Eight teprotumumab oncology trials revealed 8.1% (51/633) had Ear/Labyrinth Disorders with 2.1% (13) considered study-drug-related and 3.8% (24) hearing impairment/tinnitus-related AEs, with 1.3% (8) considered teprotumumab-related. Similar rates occurred in TED trials.GO-QOL improved in teprotumumab-treated patients without/with hearing AEs. Incidence/severity was consistent across patients with chronic and acute TED. CONCLUSIONS: These analyses indicate similar occurrence of hearing claims in patients with GD/TED alone as following teprotumumab treatment. Future analyses of incremental hearing risk from teprotumumab should utilize a priori study designs accounting for background hearing dysfunction in patients with GD/TED.
RESUMEN
OBJECTIVE: Decisions around the diagnostic evaluation for pulsatile tinnitus (PT) remain challenging. We describe the usage patterns and diagnostic accuracy of imaging modalities and propose an evidence-based diagnostic approach for undifferentiated PT. STUDY DESIGN: Retrospective. SETTING: Single otology/neurotology clinic. SUBJECTS: Patients with PT presenting between 2009 and 2020. MAIN OUTCOME MEASURES: Sensitivity, specificity, diagnostic yield, and diagnostic accuracy. RESULTS: A total of 315 subjects met inclusion criteria (74% female, mean ± SD age = 52 ± 17 years). Subjects were divided into four cohorts based on exam findings: normal (n = 229), venous cohort (n = 34), arterial cohort (n = 16), and outer/middle ear pathology cohort (n = 40). In total, 53% of patients received a nonidiopathic diagnosis for PT. The most common identifiable cause was sigmoid sinus dehiscence (78%) in the venous cohort, carotid stenosis (36%) in the arterial cohort, and glomus tumor (56%) in the outer/middle ear pathology cohort. There was a higher diagnostic rate among patients with positive exam findings compared to those with unrevealing exams ( p = 0.04). Imaging studies with the highest diagnostic yield were computed tomography (CT) venography (44%), formal angiography (42%), and magnetic resonance venography (40%); studies with the highest specificity were formal angiography (0.82), CT angiography (0.67), and CT venography (0.67). A diagnostic algorithm is proposed. CONCLUSIONS: Reaching a diagnosis in patients with PT requires a systematic approach, taking into account both clinical and radiographic information. Physical examination is a key first step for differentiating patients into venous, arterial, and other cohorts to narrow down the likely pathology and determine which radiographic studies have the highest yield and accuracy.

OBJECTIVE: To design and validate a disease-specific quality of life instrument for Meniere's disease. METHODS: We used a sequential process of expert input, patient focus groups, and analyses of responses to draft questionnaires to create a 24-item Meniere's disease quality of life (MenQOL) instrument. The MenQOL and the SF-36v2 were administered to a cohort of 50 patients with Meniere's disease and 60 comparison patients with tinnitus, vertigo, or hearing loss from other causes identified at a tertiary academic center. We performed exploratory factor analysis, Cronbach's α, between group comparisons of total MenQOL scores, and regression analyses between the MenQOL and SF-36v2 to evaluate the instrument's factor structure, internal consistency, face validity, and external validity. Segregation of the instrument into domains was assessed by exploratory factor analysis. RESULTS: Exploratory factor analysis revealed that the MenQOL has a single domain. Cronbach's α = 0.914 indicated high internal consistency for the instrument as a whole. Mean MenQOL scores showing significantly worse quality of life among patients with Meniere's disease than comparison participants (52.5 ± 15.8 vs. 43.2 ± 12.6; p = 0.0051), indicating good construct validity. Significant inverse relationships in bivariate linear regressions between total MenQOL scores and SF-36v2 physical (slope = -0.94, p < 0.0001) and mental (slope = -1.16, p < 0.0001) composite scores showed acceptable concurrent validity. CONCLUSIONS: We have described the initial development of the MenQOL, a simple, valid patient-reported outcome measure that, subject to further study, may be used to assess the effects of treatment on disease-specific quality of life in patients with Meniere's disease.

RESUMEN
OBJECTIVE: To investigate the survival benefit of elective neck dissection (END) over neck observation in surgically resected cT1-4 N0M0 head and neck basaloid carcinoma (HNBC). STUDY DESIGN: Retrospective cohort study. SETTING: The 2006 to 2017 hospital-based National Cancer Database. METHODS: Patients with surgically resected cT1-4 N0M0 HNBC were selected. Linear, binary logistic, Kaplan-Meier, and Cox proportional hazards regression models were implemented. RESULTS: Of 857 patients satisfying inclusion criteria, the majority were male (77.0%) and white (88.1%) with disease of the oral cavity (21.5%) or oropharynx (42.9%) classified as high grade (76.9%) and cT1-2 (72.9%). 389 (45.4%) patients underwent END. END utilization between 2006 and 2017 increased for cT1-2 disease (33.3% vs 56.9%, R2 = .699) but remained relatively constant for cT3-4 disease (66.7% vs 57.9%, R2 = .062). One-hundred and fifteen (29.6%) ENDs detected occult nodal metastases (ONMs). The 5-year overall survival (OS) of patients undergoing neck observation and END was 65.6% and 66.8%, respectively (P = .652). END was not associated with improved OS in survival analyses stratified by patient demographics, clinicopathologic features, and adjuvant therapy. Compared with surgery alone, adjuvant radiotherapy (adjusted hazard ratio: 0.74, 95% confidence interval [CI]: 0.57-0.97, P = .031) was associated with improved OS. END (hazard ratio [HR]: 0.96, 95% CI: 0.71-1.28, P = .770) and ONM (HR: 1.12, 95% CI: 0.78-1.61, P = .551) were not associated with OS. CONCLUSION: END is performed in nearly half of patients with HNBC but is not associated with improved OS, even after stratifying survival analyses by patient demographics, clinicopathologic features, and adjuvant therapy. The rate of ONM approaching 30%, however, justifies inclusion of END in the surgical management of HNBC.

Head and neck paragangliomas (HNPGLs) are rare and have high rates of genetic mutations. We conducted a retrospective review of 187 patients with 296 PGLs diagnosed between 1974 and 2023. The mean age of diagnosis was 48.8 years (range 10 to 82) with 69.0% female and 26.5% patients with multiple PGLs. Among 119 patients undergoing genetic testing, 70 (58.8%) patients had mutations, with SDHB (30) and SDHD (26) being the most common. The rates of metastasis and recurrence were higher among patients with SDHB mutations or SDHD mutations associated with multiple PGLs. Metabolic evaluation showed elevated plasma dopamine levels were the most common derangements in HNPGL. MRI and CT were the most common anatomic imaging modalities and DOTATATE was the most common functional scan used in this cohort. Most patients (81.5%) received surgery as the primary definitive treatment, while 22.5% patients received radiation treatment, mostly as an adjuvant therapy or for surgically challenging or inoperable cases. Systemic treatment was rarely used in our cohort. Our single-center experience highlights the need for referral for genetic testing and metabolic evaluation and for a team-based approach to improve the clinical outcomes of patients with HNPGLs.
RESUMEN
OBJECTIVE: To compare surgical and nonsurgical definitive treatment in cT4b major salivary gland cancer (MSGC). STUDY DESIGN: Retrospective cohort study. SETTING: The 2004 to 2019 National Cancer Database. METHODS: The NCDB was queried for patients with cT4b MSGC (N = 976). Patients undergoing definitive treatment with (1) surgical resection + adjuvant therapy, (2) radiotherapy (RT) alone, or (3) chemoradiotherapy (CRT) were included in Kaplan-Meier and Cox survival analyses. RESULTS: Of 219 patients undergoing definitive treatment, 148 (67.6%) underwent surgical resection + adjuvant therapy and 71 (32.4%) underwent RT or CRT. There were no documented mortalities within 90 days of surgical resection. Tumor diameter and nodal metastasis were associated with decreased odds of undergoing definitive treatment (P < 0.025). Patients with positive surgical margins (PSM) had higher 5-year overall survival (OS) than those undergoing definitive RT or CRT (48.5% vs 30.1%, P = 0.018) and similar 5-year OS as those with negative margins (48.5% vs 54.0%, P = 0.205). Surgical resection + adjuvant therapy (adjusted hazard ratio: 0.55, 95% confidence interval [CI]: 0.37-0.84) was associated with higher OS than definitive RT or CRT (P < 0.025). A separate cohort of 961 patients with cT4a tumors undergoing surgical resection + adjuvant therapy was created; cT4a and cT4b (hazard ratio: 1.02, 95% CI: 0.80-1.29, P = 0.896) tumors had similar OS. CONCLUSION: A minority of patients with cT4b MSGC undergo definitive treatment. Surgical resection + adjuvant therapy was safe and associated with higher OS than definitive RT or CRT, despite high rate of PSM. In the absence of clinical trial data, appropriately selected patients with cT4b MSGC may benefit from surgical resection.

OBJECTIVE: Undergoing surgery and adjuvant radiotherapy (aRT) at the same facility has been associated with higher overall survival (OS) in head and neck squamous cell carcinoma. Our study investigates whether undergoing surgery and aRT at the same academic facility is associated with higher OS in major salivary gland cancer (MSGC). METHODS: The 2006-2018 National Cancer Database was queried for patients with MSGC undergoing surgery at an academic facility and then aRT. Multivariable binary logistic and Cox proportional hazards regression models were implemented. RESULTS: Of 2801 patients satisfying inclusion criteria, 2130 (76.0%) underwent surgery and aRT at the same academic facility. Residence in a less populated area (adjusted odds ratio [aOR] 1.69, 95% confidence interval [CI] 1.16-2.45), treatment without adjuvant chemotherapy (aOR 1.97, 95% CI 1.41-2.76), and aRT duration (aOR 1.02, 95% CI 1.01-1.04) were associated with undergoing surgery and aRT at different facilities on multivariable logistic regression adjusting for patient demographics, clinicopathologic features, and adjuvant therapy (p < 0.01). Five-year OS was higher in patients undergoing surgery and aRT at the same academic facility (68.8% vs. 61.9%, p < 0.001). Undergoing surgery and aRT at different facilities remained associated with worse OS on multivariable Cox regression (aHR 1.41, 95% CI 1.10-1.81, p = 0.007). CONCLUSION: Undergoing surgery and aRT at the same academic facility is associated with higher OS in MSGC. Although undergoing surgery and aRT at the same academic facility is impractical for all patients, academic physicians should consider same-facility treatment for complex patients who would most benefit from clear multidisciplinary communication.

BACKGROUND: To develop machine learning (ML) models predicting unplanned readmission and reoperation among patients undergoing free flap reconstruction for head and neck (HN) surgery. METHODS: Data were extracted from the 2012-2019 NSQIP database. eXtreme Gradient Boosting (XGBoost) was used to develop ML models predicting 30-day readmission and reoperation based on demographic and perioperative factors. Models were validated using 2019 data and evaluated. RESULTS: Four-hundred and sixty-six (10.7%) of 4333 included patients were readmitted within 30 days of initial surgery. The ML model demonstrated 82% accuracy, 63% sensitivity, 85% specificity, and AUC of 0.78. Nine-hundred and four (18.3%) of 4931 patients underwent reoperation within 30 days of index surgery. The ML model demonstrated 62% accuracy, 51% sensitivity, 64% specificity, and AUC of 0.58. CONCLUSION: XGBoost was used to predict 30-day readmission and reoperation for HN free flap patients. Findings may be used to assist clinicians and patients in shared decision-making and improve data collection in future database iterations.

OBJECTIVE: The role of surgery in lateral skull base osteomyelitis (SBO) is controversial. Surgical intervention is often requested by consulting services in the interest of additional culture data to inform medical management. However, whether surgery alters subsequent antibiotic treatment or modifies disease outcome remains unknown. The aim of this study was to investigate the role of surgical intervention in the treatment of SBO by (1) comparing nonsurgical and surgical culture data and (2) assessing clinical outcomes and treatment course following surgical intervention. STUDY DESIGN: Retrospective. SETTING: Tertiary care center. METHODS: The electronic record was queried for all patients with SBO who presented to a single institution over a 16-year period (2007-2023). Information recorded included history and exam, bedside and intraoperative culture data, antibiotic course, and disease outcomes. Primary outcome measures included change in medical management based on intraoperative cultures, recurrence rates, and mortality rates. RESULTS: Forty patients (41 ears, average age 73 ± 13 years) met inclusion criteria. Out of 13 (32%) patients who underwent surgical intervention, one intraoperative culture changed the antibiotic course due to identification of resistance to the original antibiotic used. Surgery did not demonstrate a benefit in overall mortality (23% vs 18%, P = 0.36) or facial nerve function (33% vs 50%, P = 0.56) compared to medical management, and was associated with increased recurrence rates (54% vs 11%, P = 0.05). CONCLUSION: Surgical cultures rarely changed antibiotic selection. Surgical debridement in treatment-refractory SBO was also not associated with improvement in recurrence or mortality rates, though this may reflect underlying differences in disease severity.

OBJECTIVE: To characterize the estimated prevalence and clinicodemographic features of Ménière's disease (MD) using current diagnostic criteria. METHODS: A cross-sectional study was undertaken at our tertiary academic referral center. All patients seen in Otolaryngology clinic with ICD-10 diagnoses of MD, from January 1, 2013 to July 31, 2022 were identified. Chart review was undertaken to determine the estimated prevalence of MD meeting AAO-HNS diagnostic criteria. Clinicodemographic features were evaluated against a comparator group without MD seen in our health system. RESULTS: Of 806 ICD-10 diagnoses of MD, we identified 480 MD cases meeting diagnostic criteria (168 definite). Mean age at presentation for MD cases was 49 years. Forty-seven percent of cases were male. A significantly higher proportion of MD cases than comparators were white (76% vs. 66%, p < 0.001). Mean time since MD symptom onset was 6.7 years, with a mean attack duration of 4.6 h; 7.5% of MD cases reported a positive family history, and 7% had bilateral disease. The odds of reporting migraine were significantly greater among MD patients than comparators (OR 1.74 [1.26-2.42]); the odds of having autoimmune conditions were lower (OR 0.45 [0.28-0.74]); and the odds of reporting allergies were no different (OR 0.96 [0.74-1.25]) versus comparator patients after controlling for demographic characteristics. CONCLUSIONS: Among MD diagnoses, there is a low estimated prevalence of MD meeting diagnostic criteria, and an even lower prevalence of definite MD. Compared to a comparator group of patients seen for any disorder, patients with MD are more likely to be white, male, and have a history of migraine.

OBJECTIVES: Determine if intensive local therapy (i.e., local surgery or radiation) has a survival benefit for patients presenting with distantly metastatic oropharyngeal squamous cell carcinoma (OPSCC). METHODS: Retrospective population-based cohort study of patients in the National Cancer Database presenting with distantly metastatic OPSCC. Overall survival (OS) was compared for patients receiving systemic therapy alone or in combination with local surgery or curative dose radiation, controlling for various clinicodemographic factors. RESULTS: Between 2010 and 2015, 627 patients presented with newly diagnosed, metastatic OPSCC and an initial treatment course including systemic chemotherapy. Multivariable analysis demonstrated that local radiation therapy was independently associated with improved OS (OR 0.64, CI [0.51-0.81]); local surgery was not independently associated with improved OS (OR 0.99, CI [0.65-1.53]). Higher T stages were associated with worse OS (OR 1.69, CI [1.14-2.50] for T3 and OR 1.77, CI [1.22-2.58] for T4 compared to T1). HPV-positive (HPV+) tumors were associated with improved OS compared to HPV- (OR 0.79, CI [0.64-0.97]). Multiagent chemotherapy was associated with improved OS compared to single-agent (OR 0.78, CI [0.62-1.00]). The best survival for the entire cohort and for HPV+ patients was for radiation with systemic therapy and the worst survival for systemic therapy alone. CONCLUSIONS: Curative dose local radiotherapy in addition to systemic therapy is associated with improved OS compared to systemic therapy alone in patients presenting with distantly metastatic OPSCC. There is not a significant survival benefit for local surgery in addition to systemic therapy in this patient population, regardless of HPV status.

BACKGROUND: Socioeconomic variables including race, education, and income have been shown to affect vestibular schwannoma incidence, treatment, and outcomes. We sought to determine the impact of socioeconomic factors on quality of life at the time of vestibular schwannoma diagnosis. METHODS: Retrospective cohort study conducted at a tertiary academic center. All patients evaluated for vestibular schwannoma from March 1, 2010 to December 31, 2021 who completed at least one Penn Acoustic Neuroma Quality of Life (PANQOL) questionnaire at presentation or prior to any intervention were included. PANQOL scores were compared across income quintiles, racial groups, and health insurance categories. RESULTS: Two-hundred and ninety-six patients who had non-missing information on variables of interest were included. Compared to White/Caucasian patients (84.5 %), Black/African American patients (4.7 %) had significantly lower PANQOL total scores (b = -12.8[-21.7, -4.0], p = 0.005). Compared to patients with Commercial insurance (53 %), patients who were Uninsured/ Self-pay (1.7 %) had significantly lower PANQOL total scores (b = -16.7[-31.4, -1.9], p = 0.027). Patients in higher income quintiles had significantly higher PANQOL total scores (b = 11.7[3.9, 19.5], p = 0.004 comparing highest income quintile to lowest). After controlling for potential confounders, income quintile (b = 9.6[1.3, 17.9], p = 0.023 comparing highest quintile to lowest) and insurance (b = -17.0[-31.9, -21], p = 0.025 comparing Uninsured/Self-pay to Commercial insurance) remained predictors of total PANQOL score. CONCLUSIONS: Socioeconomic factors including race, health insurance, and income appear to contribute to quality of life at the time of vestibular schwannoma diagnosis. These variables are interrelated and the effects of race may be mediated in part by differences in income and health insurance coverage.

OBJECTIVES: Changes in vestibular function have been demonstrated following cochlear implantation (CI). The functional impact of these changes on CI performance has not been well-studied. We sought to assess whether caloric changes postimplantation could predict CI performance. METHODS: Retrospective review of a prospectively collected database at a tertiary care hospital. Patients who underwent CI over a 22-year period (1999-2021) and had videonystagmography (VNG) testing pre- and postimplantation were included. Caloric responses were compared pre- versus post-implantation, and assessed for their ability to predict CI performance as evaluated using AzBio +10 decibels signal-to-noise ratio (dB S/N) scores. RESULTS: 43 CI recipients were included. There was a significant difference in the average maximal slow-phase velocity in response to caloric irrigation in the implanted ear pre- versus post-operatively (21.2 vs. 18.5 deg/s; p = 0.02). Controlling for age and pre-implantation speech recognition performance, pre- and post-implantation caloric responses in the implanted ear significantly predicted CI performance at 0-6 months and >6 months post-implantation. Caloric changes following implantation were not significantly correlated with CI performance. CONCLUSION: CI impacts vestibular function as evidenced by changes in caloric responses. Vestibular function pre- and possibly post-CI may be clinically useful metrics for predicting some proportion of CI performance variability.
RESUMEN
INTRODUCTION: Management of the neck in oral cavity squamous cell carcinoma (OCSCC) is essential to oncologic control and survival. The rates of lymph node metastasis (LNM) vary based on oral cavity tumor site and stage and influence treatment decisions. The aim of this paper was to describe clinical LNM for different tumor subsites and stages of surgically managed OCSCC. METHODS: We conducted a retrospective analysis of 25,846 surgically managed OCSCC patients from the National Cancer Database (NCDB) stratified by tumor subsite and clinical T-stage. For cN + patients, rates of pathologic LNM and absence of pathologic LNM were determined. For cN0 patients, outcomes included the rates of elective neck dissection (END) and occult LNM and predictors of occult LNM determined by a multivariable logistic regression model. RESULTS: A total of 25,846 patients (59.1% male, mean age 61.9 years) met inclusion criteria with primary tumor sites including oral tongue (50.8%), floor of mouth (21.2%), lower alveolus (7.6%), buccal mucosa (6.7%), retromolar area (4.9%), upper alveolus (3.6%), hard palate (2.7%), and mucosal lip (2.5%). Among all sites, clinical N+ rates increased with T-stage (8.9% T1, 28.0% T2, 51.6% T3, 52.5% T4); these trends were preserved across subsites. Among patients with cN + disease, the overall rate of concordant positive pathologic LNM was 80.1% and the rate of discordant negative pathologic LNM was 19.6%, which varied based on tumor site and stage. In the overall cohort of cN0 patients, 59.9% received END, and the percentage of patients receiving END increased with higher tumor stage. Occult LNM among those cN0 was found in 25.1% of END cases, with the highest rates in retromolar (28.8%) and oral tongue (27.5%) tumors. Multivariable regression demonstrated significantly increased rates of occult LNM for higher T stage (T2 OR: 2.1 [1.9-2.4]; T3 OR: 3.0 [2.5-3.7]; T4 OR: 2.7 [2.2-3.2]), positive margins (OR: 1.4 [1.2-1.7]), and positive lymphovascular invasion (OR: 5.1 [4.4-5.8]). CONCLUSIONS: Management of the neck in OCSCC should be tailored based on primary tumor factors and considered for early-stage tumors.

The human auditory system encodes sound with a high degree of temporal and spectral resolution. When hearing fails, existing neuroprosthetics such as cochlear implants may partially restore hearing through stimulation of auditory neurons at the level of the cochlea, though not without limitations inherent to electrical stimulation. Novel approaches to hearing restoration, such as optogenetics, offer the potential of improved performance. We review signal processing in the ascending auditory pathway and the current state of conventional and emerging neural stimulation strategies at various levels of the auditory system.
RESUMEN
Importance: Despite the sizeable global burden of hearing loss, cochlear implants have poor penetrance among eligible hearing-impaired individuals. Identifying populations who may benefit from a cochlear implant but among whom penetrance is poor is an important aim in reducing the health-related and economic effects of hearing loss on both individuals and society. Objectives: To explore the association of socioeconomic status (SES) with cochlear implant candidacy and the decision to undergo cochlear implantation. Design, Setting, and Participants: This retrospective cohort study was performed in a tertiary academic center. All adult patients evaluated for cochlear implant candidacy from January 1, 1999, through December 31, 2022, were included in the analysis. Exposures: Household income quintile and rural or urban residence were used as proxies for SES based on zip code linkage to US Census and US Department of Agriculture data. Main Outcomes and Measures: Odds of cochlear implant candidacy and surgery. Results: A total of 754 individuals underwent candidacy evaluations and were included in the analysis (386 [51.2%] women; mean [SD] age, 64.0 [15.7] years). Of these, 693 (91.9%) were cochlear implant candidates, and 623 candidates (89.9%) underwent cochlear implantation. Multivariable analyses demonstrated that individuals in the highest income quintile had lower odds of cochlear implant candidacy compared with those in the lowest income quintile (odds ratio [OR], 0.26 [95% CI, 0.08-0.91]), and candidates in the highest income quintile had greater odds of undergoing cochlear implant surgery compared with those in the lowest quintile (OR, 2.59 [95% CI, 1.14-5.86]). Living in a small town or a micropolitan or rural area was associated with lower odds of undergoing cochlear implant surgery compared with living in a metropolitan core (OR, 0.18 [95% CI, 0.04-0.83]) after controlling for distance to the primary implant center. Conclusions and Relevance: The findings of this cohort study suggest that individuals with higher SES are less likely to qualify for a cochlear implant; however, those who qualify are more likely to undergo surgery compared with those with lower SES. These findings highlight a hearing health care disparity that should be addressed through further studies to guide population-based initiatives.

BACKGROUND: Management of the neck in laryngeal squamous cell carcinoma (LSCC) is essential to oncologic control and survival. We aim to describe patterns and rates of clinical/pathologic lymph node disease, elective neck dissection (END), and occult lymph node metastasis (LNM) in patients with surgically-managed LSCC. METHODS: Retrospective cohort study of patients in the National Cancer Database (NCDB) diagnosed with LSCC between January 2004 and December 2016 who underwent primary surgery. RESULTS: Seven thousand eight hundred and seventy-six patients met inclusion criteria. For cN0 patients, the rates of END and occult LNM both increased with tumor stage and were highest for supraglottic tumors. Predictors of occult LNM included supraglottic site, pathologic T3 and T4 stage, positive margins, and presence of lymphovascular invasion (p < 0.05). CONCLUSIONS: The propensity for cervical LNM in surgically-managed LSCC varies based on primary tumor site and stage, and a variety of disease factors increase risk of occult LNM.

Background Sinonasal undifferentiated carcinoma (SNUC) is a rare, aggressive malignancy with a poor prognosis, and multimodal therapy is the standard of care. We sought to characterize treatment delays in SNUC managed with surgery and adjuvant radiation and to determine the impact on survival using the National Cancer Database (NCDB). Methods This was a retrospective, population-based cohort study of patients with SNUC between 2004 and 2016 in the NCDB. The intervals of diagnosis to surgery (DTS), surgery to radiation (SRT), and radiation duration (RTD) were examined. Recursive partitioning analysis (RPA) was performed to identify the variables with the greatest impact on survival. The association between treatment delay and overall survival (OS) was then assessed using multivariate Cox proportional hazards regression. Results Of 173 patients who met inclusion criteria, 65.9% were male, average age at diagnosis was 56.6 years, and 5-year OS was 48.1%. Median durations of DTS, SRT, and RTD were 18, 43, and 46 days, respectively. Predictors of treatment delay included Black race, government insurance excluding Medicare/Medicaid, and positive margins. RPA-derived optimal thresholds were 29, 28, and 38 days for DTS, SRT and RTD, respectively. On multivariate analysis, positive margins (hazard ratio [HR]: 4.82; 95% confidence interval [CI]: 2.28-10.2) and DTS less than 29 days (HR: 2.41; 95% CI: 1.23-4.73) were associated with worse OS. Conclusion Our results likely reflect the aggressive nature of the disease with surgeons taking more invasive disease to the operating room more quickly. Median treatment intervals described may serve as relevant national benchmarks.
