Abstract
Objective To examine the current geographic distribution of otolaryngologists in the United States and the disparities in socioeconomic demographics at the county and hospital referral region (HRR) level. Study Design Cross-sectional study. Setting National cohort analysis including all otolaryngologists in the United States. Subjects and Methods All otolaryngologists board certified by the American Board of Otolaryngology–Head and Neck Surgery in the United States in 2018 were compared with overlaid demographic data from the 2010 United States Census Bureau by county and HRR. Associations between the density of otolaryngologists per population and socioeconomic characteristics were assessed and stratified by region. Results The average number of otolaryngologists was 3.6 (SD 9.6) per 100,000. On multivariable regression analysis, the density of otolaryngologists was positively associated with counties with the highest quartile of college education (1.8 providers per 100,000 [95% confidence interval [CI] 0.89, 2.90], P < .001) and income (2.1 providers per 100,000 [95% CI 1.03, 3.07], P = .01). Significant regional variation existed in access to otolaryngology care. Conclusion There are significant areas with disparate densities of otolaryngologists in the United States. Lower socioeconomic status, more severe poverty, and a lower number of college graduates in a county correlated with reduced density of otolaryngologists.

Abstract
Surgical removal with negative margins is the preferred management of oral squamous cell carcinomas. This review summarizes statements by professional organizations and data supporting the specimen-driven approach to margin assessment. Practical aspects of the intraoperative margin assessment, as guided by gross examination, are presented. The most cost- and time-efficient method of intraoperative margin assessment depends on desired margin clearance and likelihood of other adverse histologic factors, such as extranodal extension, perineural invasion, which are likelier in advanced carcinomas. Intraoperative surgeon-pathologist communication can be improved by reporting to surgical team gross distances to all or selected closest margins, before choosing margins for microscopic frozen examination. Case specific mitigation strategies to minimize the negative impact of tumor-bed driven margin assessment or of suboptimal margin revision are proposed. Based on size, shape, histology, size of carcinoma at the margin, and orientation of the additional tissue, margin revision may be judged as adequate (conversion of a positive margin into a negative one), inadequate (positive margin remains positive), or indeterminate. The significance of anatomic subsite based labeling, radial margin sampling from the main resection specimen, and the relationship between the distance to closest margin and local control are highlighted. The modern definition of safe margin would account for other parameters, such as perineural invasion. An updated approach to resolution of frozen versus permanent sampling issues is outlined. Future studies are needed to design and validate risk models that would help to determine for individual patient what represents a safe margin and how to judge the quality of margin revision.

Abstract
PURPOSE This study aimed to examine the factors associated with diagnosed depression among patients with a metastatic cancer. METHODS We conducted a cross-sectional analysis of 39,223 hospital records from 2008 to 2013 National Inpatient Sample for patients with metastatic cancer. Diagnosed depression was defined using ICD-9-CM for major depression. Weighted, multivariable hierarchical regression model was used to examine the association between sociodemographic and clinical factors and depression among patients with a metastatic cancer. RESULTS The prevalence of clinically diagnosed depression in patients with a metastatic cancer in our study sample was 7.3% (5.9% for males and 8.6% for females). The prevalence rate of diagnosed depression increased from 5.3 to 9.4% between 2008 and 2013. In multivariable analysis, patients were more likely to be diagnosed with depression if they were females (aOR = 1.44; 95% CI 1.25-1.66) compared to males; and had higher number of comorbidities (aOR = 1.11 per 1-unit increase in Elixhauser comorbidity score, 95% CI 1.07-1.15). In contrast, patients were less likely to be diagnosed with depression if they were blacks (aOR = 0.59; 95% CI 0.47-0.74) or other race (aOR = 0.58; 95% CI 0.47-0.72) compared with white patients. CONCLUSIONS Women and individuals with more comorbidities were diagnosed with depression more frequently, whereas black patients were diagnosed less. Our findings could help providers to identify hospitalized patients with the higher risk of depression and screened patients with signs and symptoms of clinical depression.

Abstract
OBJECTIVES To describe a 10-year single center experience with parotid gland malignancies and to determine factors affecting outcomes. STUDY DESIGN Retrospective review. METHODS The institutional cancer registry was used to identify patients treated surgically for malignancies of the parotid gland between January 2005 and December 2014. Clinical and pathologic data were collected retrospectively from patient charts and analyzed for their association with overall survival (OS) and disease-free survival (DFS). RESULTS Two hundred patients were identified. Mean age at surgery was 57.8 years, and mean follow-up time was 52 months. One hundred two patients underwent total parotidectomy, while 77 underwent superficial parotidectomy, and 21 underwent deep lobe resection. Seventy patients (35%) required facial nerve (FN) sacrifice. Acinic cell carcinoma was the most common histologic type (22%), followed by mucoepidermoid carcinoma (21.5%) and adenoid cystic carcinoma (12.5%). Twenty-nine patients (14.5%) experienced recurrences, with mean time to recurrence of 23.6 months (range: 1-82 months). Five- and 10-year OS were 81% and 73%, respectively. Five- and 10-year DFS were 80% and 73%, respectively. In univariate analyses, age > 60, histologic type, positive margins, high grade, T-stage, node positivity, perineural invasion, and FN involvement were predictors of OS and DFS. In the multivariate analysis, histology, positive margins, node positivity, and FN involvement were independent predictors of OS and DFS. CONCLUSIONS Our single-center experience of 200 patients suggests that histology, positive margins, node positivity, and FN involvement are independently associated with outcomes in parotid malignancies. LEVEL OF EVIDENCE 4.

Abstract
OBJECTIVES Quantify by immunohistochemistry (IHC) a partial epithelial-to-mesenchymal transition (p-EMT) population in oral cavity squamous cell carcinoma (OCSCC) and determine its predictive value for lymph node metastasis. METHODS Tissue microarrays (TMA) were created using 2 mm cores from 99 OCSCC patients (47 with low volume T2 disease, 52 with high volume T4 disease, and ∼50% in each group with nodal metastasis). IHC staining was performed for three validated p-EMT markers (PDPN, LAMB3, LAMC2) and one marker of well-differentiated epithelial cells (SPRR1B). Staining was quantified in a blinded manner by two reviewers. Tumors were classified as malignant basal subtype based on staining for the four markers. In this subset, the p-EMT score was computed as the average of p-EMT markers. RESULTS 84 tumors were classified as malignant basal. There was 87% inter-rater consistency in marker quantification. There were associations of p-EMT scores with higher grade (2.15 vs. 1.92, p = 0.04), PNI (2.13 vs. 1.83, p = 0.003), and node positivity (2.09 vs. 1.87, p = 0.02), including occult node positivity (56% vs. 19%, p = 0.005). P-EMT was independently associated with nodal metastasis in a multivariate analysis (OR 3.12, p = 0.039). Overall and disease free survival showed trends towards being diminished in the p-EMT high group. CONCLUSIONS IHC quantification of p-EMT in OCSCC primary tumors is reliably associated with nodal metastasis, PNI, and high grade. With prospective validation, p-EMT biomarkers may aid in decision-making over whether to perform a neck dissection in the N0 neck and/or for adjuvant therapy planning.

Abstract
OBJECTIVES To investigate methods used by head and neck surgeons to pre-operatively measure depth of invasion (DOI) in light of the new staging for oral cavity squamous cell carcinoma (OCSCC). MATERIALS AND METHODS A survey was designed and sent to all American Head and Neck Society (AHNS) members via an email link. The last response was recorded on January 16, 2019. RESULTS We received 185 (13.3%) responses from 184 surgeons and 1 radiation oncologist. The majority of surgeons correctly identified DOI (78.9%) and indicated measuring DOI pre-operatively (86%). The most common methods for measuring DOI were manual palpation (32.5%) and full thickness biopsy (25.2%). In addition, most surgeons (84.7%) reported using a DOI threshold (in mm) as their primary criterion in their decision to pursue a neck dissection in the N0 neck. The most common reported threshold was 4 mm (37.4% of those that reported using DOI), however, the range varied from 2 to >10 mm. Two-thirds of surgeons considered DOI an important indicator for adjuvant therapy. CONCLUSION DOI is believed to be an important prognostic indicator guiding neck dissection and the need for adjuvant therapy. While most surgeons currently measure DOI pre-operatively, most use subjective methods. Future studies are needed to establish objective pre-operative DOI measurement techniques and to better inform the decision to perform prophylactic neck dissection, given the current majority practice of prophylactic neck dissection for DOI of 4 mm or greater.

Abstract
Patient advocacy organizations (PAOs) are nonprofits dedicated to benefiting patients and their families through activities such as education/counseling and research funding. Although medical drug/device companies may serve as important partners, industry donations may bias the efforts of PAOs. We conducted a retrospective cross-sectional analysis of the Kaiser Health News nonprofit database to identify and characterize otolaryngologic PAOs (n = 32) active in 2016. Among these PAOs, half (n = 16, 50.0%) focused on otologic diseases, and mean total annual revenue was $3.1 million. Among the 15 PAOs (46.9%) with publicly available donor lists, 10 (66.7%) received donations from industry. Few PAOs publicly reported the total amount donated by industry (n = 3, 9.4%) or published policies for mitigating potential financial conflicts of interest with donors (n = 3, 9.4%). Requiring drug and device companies to publicly report donations to PAOs may help patients, providers, and policy makers to better understand advocacy by these influential stakeholders.

Abstract
Abstract
Recent single cell expression profiling of head and neck squamous cell carcinoma (HNSCC) identified a partial epithelial-to-mesenchymal transition (p-EMT) subpopulation of cancer cells. We have previously demonstrated an association of p-EMT subpopulations with adverse clinical and pathologic features, in both TCGA expression data and an independent cohort of single institutional patients. Here, we aim to understand cellular co-expression of EMT markers and spatial relationships with immune infiltrates in oral cavity HNSCC. Paraffin blocks of 10 oral cavity HNSCC patients whose tumors had previously undergone single cell expression profiling were characterized by a 13-marker panel of tumor cell, p-EMT, epithelial differentiation, and immune markers. Multiplexed immunofluorescence was used to perform simultaneous staining within two serial tissue sections. Multispectral imaging was performed using wide field microscopy (Vectra 3), and algorithms were used for spectral unmixing, tissue and cell segmentation, and cell phenotyping. Following user training, tissue and cell segmentation and cell phenotyping were successfully performed in an automated fashion. Whole slides containing entire tissue sections were analyzed, enabling high throughput analysis of hundreds of thousands of individual cells per tumor. p-EMT quantification by tumor, as measured by simultaneous signal for p-EMT markers, showed consistent co-localization, in accordance with prior single cell expression profiling data. We found that individual cells defined as p-EMT positive, based on co-expression of two or more p-EMT markers, co-localized to the leading edge of tumor nests, in close apposition to the stroma. Co-localization of LAMB3 and LAMC2 was the most robust marker combination defining this subpopulation. In addition, helper and cytotoxic T cells were identified across tumors, including activated and exhausted T-cell subsets. The relationships of these cellular subpopulations to other immune cells, which may drive immune cell exhaustion, were explored by radial measurements associated with cell densities and intercellular distances. Tumor and immune cell profiling using 13 markers across serial sections enabled high throughput characterization of individual cells with spatial information in a manner not previously possible. Distinct spatial relationships among p-EMT and epithelial tumor cells were identified, including a potential correlation with immune cells. This technology may have clinical utility in HNSCC, which includes predicting the need for therapy and response to immunotherapy.

Abstract
Plunging ranulas are most often treated surgically; various surgical approaches may be necessary depending on the unique characteristics of each case. Here, we present the case of a plunging ranula noted on imaging to have a cordlike tether, which was revealed intraoperatively to be the lingual nerve. This case illustrates the importance of preoperative imaging for surgical planning, and when a transcervical approach may be the best choice for plunging ranulas.

Abstract
OBJECTIVE To examine global surgery involvement among general members of the American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) and characterize international otolaryngology surgical interventions. METHODS Data on global surgery involvement were derived from responses provided by voluntary online survey respondent members of the AAO-HNS, obtained in October 2017. These data were compared against World Bank metrics of national health expenditure and surgical specialists per capita as benchmarks for need. RESULTS There were 362 responses (response rate of 3.7%). A large proportion of respondents reported being involved in global surgery (61.3%). Locations where respondents worked included: South America (13.3%), Central America (17.7%), Caribbean (10.2%), Europe (4.1%), Africa (16.3%), Asia (16.6%), the Middle East (4.1%), and Oceania (3.6%). A greater proportion of respondents reported traveling to locations that have lower health care expenditure per capita and lower mean number of surgical specialists per 100,000 people, according to data from the World Bank. The primary purpose of trips was most commonly surgical mission (60.3%), followed by education (37.8%), and research (1.9%). CONCLUSION Members of the AAO-HNS are active in global surgery efforts around the world. Collaboration among members of the AAO-HNS may serve to improve long-term sustainability of these efforts.

Abstract
BACKGROUND/AIMS The importance of adjuvant radiotherapy in patients with close margin resections for mucoepidermoid carcinoma of the parotid gland remains unclear. METHODS Patients who underwent parotidectomy for mucoepidermoid carcinoma with or without adjuvant radiotherapy at a single academic tertiary care center from 2000 to 2014 were identified. Included patients had negative but close (≤2 mm) surgical margins without other high-risk histopathological factors including advanced T-stage, positive nodal disease, lymphovascular or perineural invasion, or high-grade histology. RESULTS Nineteen patients were identified, of whom 15 (79%) were observed postoperatively, while 4 (21%) underwent adjuvant radiotherapy. There were no significant differences in extent of parotidectomy, elective neck dissection, T staging, or tumor size between patients who were observed and those undergoing adjuvant radiation. There were no locoregional or distant recurrences in any patients at a mean follow up 74.3 months. Patients undergoing adjuvant radiation, however, had significantly more intermediate-grade as compared to low-grade histology (75% vs. 13%, difference 62%, 95% CI 4% to 100%). CONCLUSIONS Patients with negative but close (≤2 mm) surgical margins without other high-risk histopathological factors have excellent long-term locoregional control with surgery alone. The effects of adjuvant radiotherapy for those who have intermediate-grade disease remain uncertain.

Abstract
OBJECTIVES To compare local recurrence-free survival (LRFS) in early oral cavity cancer (OCC) patients with positive/close frozen section (FS) cleared with further resection (R1 to R0) or positive FS not cleared (R1) to those with negative margins on initial FS analysis (R0). DATA SOURCES PubMed, EMBASE, and Cochrane. REVIEW METHODS We followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) for reporting in our study. Only English-language articles that included patients with OCC and local recurrence (LR) comparisons between R0 and initially R1 to final R0 or final R1 groups were included. We requested the raw data from the corresponding authors of eligible studies and performed an individual participant data (IPD) meta-analysis of LRFS outcomes across groups. RESULTS Pooled LRFS data from 8 studies showed that patients in the R1 to R0 group had worse LRFS compared to the R0 group (hazard ratio [HR] = 2.897, P < .001). Patients in the R1 group were also found to have worse LRFS compared to the R0 group (HR = 3.795, P < .001). When compared to final R1 group, the initially R1 to final R0 only showed a trend toward better LRFS. CONCLUSION Margin revision of initially positive margins to "clear" based on FS guidance does not equate to an initially negative margin and does not significantly improve local control. These findings call into question the effectiveness of the current methodology of intraoperative FS in OCC resections and call for a prospective study to determine what system of resected specimen analysis best predicts completeness of resection.

[PMID: 30900256 DOI: 10.1002/lary.27929] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2018] [Revised: 02/12/2019] [Accepted: 02/22/2019] [Indexed: 12/17/2022]
Abstract
OBJECTIVES Incidence trends and outcomes of head and neck cancer (HNC) among female patients are not well understood. The objective of this study was to estimate incidence trends and quantify the association between health insurance status, stage at presentation, and survival among females with HNC. STUDY DESIGN Retrospective cohort study. METHODS The Surveillance, Epidemiology, and End Results database (2007-2014) was queried for females aged ≥18 years diagnosed with a malignant primary head and neck cancer (HNC) (n = 18,923). Incidence trends for stage at presentation were estimated using Joinpoint regression analysis. The association between health insurance status and stage at presentation on overall and disease-specific survival was estimated using Fine and Gray proportional hazards models. RESULTS Incidence of stage IV HNC rose by 1.24% from 2007 to 2014 (annual percent change = 1.24, 95% CI 0.30, 2.20). Patients with Medicaid (adjusted odds ratio [aOR] = 1.59, 95% confidence interval [CI] 1.45, 1.74) and who were uninsured (aOR = 1.73, 95% CI 1.47, 2.04) were more likely to be diagnosed with advanced stage (stages III/IV) HNC. Similarly, patients with Medicaid (adjusted hazard ratio [aHR] = 1.47, 95% CI 1.38, 1.56) and who were uninsured (aHR =1.45, 95% CI 1.29, 1.63) were more likely to die from any cause compared to privately insured patients. Medicaid (aHR = 1.34, 95% CI 1.24, 1.44) and uninsured (aHR = 1.41, 95% CI 1.24, 1.60) patients also had a greater hazard of HNC-specific deaths compared to privately insured patients. CONCLUSIONS Incidence of advanced-stage presentation for female HNC patients in the United States has increased significantly since 2007, and patients who are uninsured or enrolled in Medicaid are more likely to present with late stage disease and die earlier.

Abstract
OBJECTIVES The Milan System for Reporting Salivary Gland Cytopathology (MSRSGC) established a standardized, tiered reporting system for salivary gland fine-needle aspiration (FNA) that has gained international acceptance among cytologists. Our goal was to review the key features of the MSRSGC to familiarize the surgical community with this system and its application to the FNA evaluation of salivary gland masses. METHODS A comprehensive review of the MSRSGC and its application in clinical practice. RESULTS The MSRSGC consists of six major diagnostic categories: 1) nondiagnostic, 2) non-neoplastic, 3) atypia of undetermined significance, 4) neoplasm (benign or salivary gland neoplasm of uncertain malignant potential), 5) suspicious for malignancy, and 6) malignant. Each diagnostic category is associated with an implied risk of malignancy with implications for clinical management. CONCLUSIONS The MSRSGC is similar to the system used for reporting thyroid FNA, which is familiar to most otolaryngologists and head and neck surgeons. As this reporting system continues to gain popularity among pathologists, widespread understanding by surgeons will be important to standardize communication and classification of salivary gland cytopathology to improve clinical care.

Abstract
BACKGROUND A reliable method of measuring functional outcomes is essential to inform treatment decisions in head and neck cancer. METHODS Members of the American Head and Neck Society were surveyed regarding their use of functional outcome assessment tools. Qualitative statistical analysis was performed to identify major tools used and to clarify obstacles to functional outcome assessment. A comprehensive literature review was performed to identify available tools. RESULTS A total of 142 surgeons were surveyed. 44.12% of respondents use at least 1 tool to assess functional outcomes. The most frequently used tools were modified barium swallow, MD Anderson Dysphagia Inventory, and functional endoscopic evaluation of swallow (FEES). 72.65% of respondents reported barriers to assessment, most frequently a lack of support to administer the tests or to collect, apply or analyze the results. Review of the literature revealed 173 available tools. CONCLUSIONS Although a wide variety of validated tools are available in the literature to assess functional outcomes after head and neck surgery, major obstacles to their use persist. The lack of a standard measure that is practical and transferable continues to impair research progression in this field.

Abstract
Head and neck cancers account for a significant proportion of reported malignancies in the United States; however, multiple concurrent primary malignancies from different sites are rare. We describe the case of a 44-year-old man simultaneously diagnosed with three independent head and neck malignancies (adenocarcinoma in minor salivary gland, papillary thyroid carcinoma, and acinic cell carcinoma) in the setting of Lynch syndrome. To our knowledge, this is the first case of multiple head and neck malignancies arising simultaneously from Lynch syndrome. This case highlights the need for diligent workup in patients with hereditary conditions that predispose to malignancies. Laryngoscope, 128:2759-2761, 2018.

Cancer 2018; 124:4072-4079. [PMID: 30335190 DOI: 10.1002/cncr.31675] [Citation(s) in RCA: 118] [Impact Index Per Article: 19.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2018] [Revised: 06/21/2018] [Accepted: 06/25/2016] [Indexed: 01/18/2023]
Abstract
BACKGROUND Cancer survivors face psychosocial issues that increase their risk of suicide. This study examined the risk of suicide across cancer sites, with a focus on survivors of head and neck cancer (HNC). METHODS The Surveillance, Epidemiology, and End Results 18-registry database (from 2000 to 2014) was queried for the top 20 cancer sites in the database, including HNC. The outcome of interest was suicide as a cause of death. The mortality rate from suicide was estimated for HNC sites and was compared with rates for 19 other cancer sites that were included in the study. Poisson regression was used to estimate adjusted rate ratios (aRRs) and 95% confidence intervals (CIs) for 1) HNC versus non-HNC sites (the other 19 cancer sites combined), and 2) HNC versus each individual cancer site. Models were stratified by sex, controlling for race, marital status, age, year, and stage at diagnosis. RESULTS There were 404 suicides among 151,167 HNC survivors from 2000 to 2014, yielding a suicide rate of 63.4 suicides per 100,000 person-years. In this timeframe, there were 4493 suicides observed among 4219,097 cancer survivors in the study sample, yielding an incidence rate of 23.6 suicides per 100,000 person-years. Compared with survivors of other cancers, survivors of HNC were almost 2 times more likely to die from suicide (aRR, 1.97; 95% CI, 1.77-2.19). There was a 27% increase in the risk of suicide among HNC survivors during the period from 2010 to 2014 (aRR, 1.27; 95% CI, 1.16-1.38) compared with the period from 2000 to 2004. CONCLUSIONS Although survival rates in cancer have improved because of improved treatments, the risk of death by suicide remains a problem for cancer survivors, particularly those with HNC.
