Refining parotid acinic cell carcinoma treatment: Balancing risk factors and extent of resection.

OBJECTIVES: Acinic cell carcinoma (ACC) most frequently arises in the parotid gland. Treatment consists of surgical resection and sometimes adjuvant therapy. ACC is most often a low-grade malignancy with good prognosis. Higher-grade tumors are often treated aggressively with total parotidectomy, neck dissection, and adjuvant therapy; however, the effect of parotid gland resection extent on oncologic outcomes has not been studied. Herein, we examine predictors of oncologic outcomes, including the effect of extent of resection. METHODS: Patients with diagnosis of parotid ACC treated at our institution were included in this retrospective study. Patient factors were examined, and patients were grouped by extent of resection and tumor grade. RESULTS: 58 patients, including 32 low-grade, 7 intermediate-grade, and 14 high-grade were included. Patients with low-grade tumors were more likely to undergo lesser extent of parotidectomy and less likely to undergo neck dissection. Two patients with low grade tumors developed recurrence, one local and one regional. Recurrence rate did not differ with resection extent in low-grade tumors. High tumor grade was found to be associated with disease progression. There was no association with adjuvant treatment and outcomes. Across all tumor grades advanced AJCC stage was found to be associated with disease progression. CONCLUSIONS: In ACC patients with low-grade tumors and lower disease stage who undergo lesser extent of surgical resection oncologic outcomes were favorable. Patients with high-grade tumors carry a high risk of recurrence, despite aggressive treatment. AJCC stage and histopathologic grade may predict outcomes and guide treatment.

Partial superficial parotidectomy for pleomorphic adenoma of the parotid gland: Early post-operative outcomes.

INTRODUCTION: There has been historical controversy regarding the extent of resection in the management of pleomorphic adenomas. This study aims to evaluate the extent of surgery and short-term postoperative outcomes of partial superficial parotidectomy (PSP) for the management of pleomorphic adenomas at a tertiary, high-volume center. METHODS: A retrospective chart review of patients who underwent PSP was performed. Variables included demographics, pre-operative facial nerve function, operative techniques, postoperative complications/facial nerve function, and recurrence. RESULTS: 151 adults who underwent PSP for pleomorphic adenoma from January 1st, 2000 to December 31st, 2022 were identified. Median age was 55 (IQR 40-66) years with females representing 74 % of the cohort. Median tumor size at presentation was 1.8 (IQR 1.3-2.3) cm. Baseline facial nerve function was excellent for most patients (House-Brackmann I, 99 %). Most patients underwent a superficial inferior parotidectomy (88 %). Modified Blair incision (70 %) was the most common incision. Intraoperatively, the facial nerve was identified in 149 (99 %) patients. The main trunk was identified in 126 (85 %) patients. No patient had tumor spillage. Only two patients required parotid bed reconstruction. The most common complication was ear numbness (60 %). Postoperatively, 114 patients were House-Brackmann grade I at both preoperative and postoperative assessment, 8 went from grade I to II, and 1 went from grade VI to II (Bell's palsy that resolved to grade II following surgery). Median follow-up was 1(IQR 1-5) month. CONCLUSION: PSP is efficacious in the management of pleomorphic adenomas with preservation of facial nerve function, and minimal post-operative complications. Future study is needed to assess long term recurrence risk.

Safety outcomes and patient convenience in outpatient parotidectomy.

BACKGROUND: Parotidectomies have historically been performed on an inpatient basis despite being well-tolerated surgeries with minimal postoperative wound care and low rates of complications at high-volume institutions. Past studies have supported the safety of outpatient surgery for parotidectomy but have been limited to superficial parotidectomy and have not addressed the patient experience surrounding the surgical intervention such as pre-operative and post-operative care and communication. PURPOSE: This study assesses the impact of outpatient superficial, deep, and partial parotid surgery on various parameters including surgical safety, distance traveled for care, utilization of telehealth, and patient-initiated communication. MATERIALS AND METHODS: Retrospective study from January 2020 to October 2021. Patients undergoing superficial lobe, deep lobe, and partial parotidectomies for benign and malignant pathologies were divided into inpatient and outpatient cohorts. A multivariable model examined the relationship between admission status and surgical complications, adjusted for age, sex, and tumor size. RESULTS: 159 patients total, 94 outpatient and 65 inpatients. No statistical difference in rates of surgical complications with the exception of salivary leak. There was an increased rate of salivary leak reported in the inpatient group (OR 5.4, 95 % CI 1.6 to 18.0, p = 0.01). Mean patient travel distance of 354 miles one-way. Post-operatively, 76 % were evaluated via video visit. Following discharge, >55 % of patients initiated communication with the surgical team, which was not statistically different between the groups. CONCLUSIONS: Outpatient parotidectomy is safe and can be more convenient, but telehealth communication must be balanced with rigorous attention to patient education.

Cannabidiol and Beta-Caryophyllene in Combination: A Therapeutic Functional Interaction.

Cannabis contains over 500 distinct compounds, which include cannabinoids, terpenoids, and flavonoids. However, very few of these compounds have been studied for their beneficial effects. There is an emerging concept that the constituents of the cannabis plant may work in concert to achieve better therapeutic benefits. This study is aimed at determining if the combination of a minor cannabinoid (cannabidiol, CBD) and a terpene (beta-caryophyllene, BCP) works in concert and if this has any therapeutic value. We used an inflammatory pain model (formalin) in mice to test for any functionality of CBD and BCP in combination. First, we determined the analgesic effect of CBD and BCP individually by establishing dose-response studies. Second, we tested the analgesic effect of fixed-ratio combinations and monitored any adverse effects. Finally, we determined the effect of this combination on inflammation. The combination of CBD and BCP produces a synergistic analgesic effect. This effect was without the cannabinoid receptor-1 side effects. The analgesic effect of CBD and BCP in combination involves an inflammatory mechanism. The combination of these two constituents of the cannabis plant, CBD and BCP, works in concert to produce a therapeutic effect with safety profiles through an inflammatory mechanism.

Behavioral Evidence for a Tau and HIV-gp120 Interaction.

Despite successful virologic control with combination antiretroviral therapy (cART), about half of people living with the human immunodeficiency virus-1 (HIV) develop an HIV-associated neurocognitive disorder (HAND). It is estimated that 50% of individuals who are HIV-positive in the United States are aged 50 years or older. Therefore, a new challenge looms as individuals living with HIV increase in age. There is concern that Alzheimer's disease (AD) may become prevalent with an earlier onset of cognitive decline in people living with HIV (PLWH). Clinical data studies reported the presence of AD biomarkers in PLWH. However, the functional significance of the interaction between HIV or HIV viral proteins and AD biomarkers is still not well studied. The main goal of the present study is to address this knowledge gap by determining if the HIV envelope glycoprotein 120 (HIV-gp120) can affect the cognitive functions in the Tau mouse AD model. Male Tau and age-matched, wild-type (WT) control mice were treated intracerebroventricularly (ICV) with HIV-gp120. The animals were evaluated for cognitive function using a Y-maze. We found that HIV-gp120 altered cognitive function in Tau mice. Notably, HIV-gp120 was able to promote a cognitive decline in transgenic Tau (P301L) mice compared to the control (HIV-gp120 and WT). We provide the first in vivo evidence of a cognitive interaction between an HIV viral protein and Tau mice.

Recurrent pleomorphic adenoma of the parotid gland: A comparison of radiographic and pathologic tumor burden.

PURPOSE: To compare recurrent pleomorphic adenoma tumor burden as detected on magnetic resonance and computerized tomography imaging with postoperative histopathology. MATERIALS AND METHODS: 44 patients were identified at a tertiary medical center between 2000 and 2015. Patients were included if they had viewable preoperative imaging and a postoperative diagnosis of recurrent pleomorphic adenoma. Primary outcomes were differences in the number and size of lesions detected on imaging and pathology. RESULTS: The size in greatest dimension between pathology and imaging was not significant on aggregate MRI + CT (p = 0.78), MRI (p = 0.41), or CT (p = 0.69). There were more lesions found on pathology compared to both aggregate MRI + CT (p = 0.003) and CT alone (p = 0.014). The number of lesions between MRI and pathology failed to reach significance (p = 0.06). On univariate analysis, the interval between imaging and pathology (recurrent surgery) did not significantly affect the number of lesions detected (p = 0.18). On multivariable analysis, CT as the primary imaging modality and >1 recurrence was independently associated with greater inaccuracy with respect to number of lesions detected (p = 0.006; p = 0.008). CONCLUSION: The size of the largest lesion on pathology can be accurately determined with imaging. Compared to MRI, CT scans significantly underpredict the number of lesions found on pathology. MRI should be prioritized unless contraindications exist. These findings will help guide imaging choice, preoperative planning, and patient counseling.

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

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.

Evaluation of proposed staging systems for human papillomavirus-related oropharyngeal squamous cell carcinoma.

BACKGROUND: Patients with human papillomavirus (HPV)-related oropharyngeal cancer (OPC) have improved survival when compared with those with HPV-negative OPC. Unfortunately, the American Joint Committee on Cancer seventh edition (AJCC-7ed) staging system does not account for the prognostic advantage observed with HPV-positive OPC. The purpose of the current study was to validate and compare 2 recently proposed staging systems for HPV-positive OPC. METHODS: Patients treated for HPV-positive OPC from 2005 to 2015 at Johns Hopkins Hospital (JHH) were included for analysis. The International Collaboration on Oropharyngeal cancer Network for Staging (ICON-S) and The University of Texas MD Anderson Cancer Center (MDACC) staging systems were applied and survival was calculated using Kaplan-Meier methods. Cox proportional hazard regression was used to determine the relationship between stage of disease and survival. Models were compared using the Akaike information criterion (AIC). RESULTS: A total of 435 patients were eligible for analysis. There was a dramatic shift in lymph node category and overall stage of disease when ICON-S and MDACC stage were applied to the JHH cohort. There was superior stratification of overall survival and progression-free survival by ICON-S stage. Both proposed models had an improved fit based on AIC scores (P<.001 for both) over the AJCC-7ed. The ICON-S staging system had the lowest AIC score, and thus a better fit within the JHH population. CONCLUSIONS: The current analysis provides external validation for both staging systems in an independent and heterogeneously treated patient population. Although the MDACC staging system is an improvement over the AJCC-7ed, the ICON-S stage provides superior stratification of overall and progression-free survival, thereby supporting its use as the updated AJCC staging system for OPC.

Genetic alterations in salivary gland cancers.

Salivary gland cancers are an incredibly heterogeneous group of tumors that include 24 histologically distinct tumor types. The use of new genetic methods has paved the way for promising advancements in our understanding of the molecular biology underlying each type of tumor. The objective of this review was to highlight common oncogenes, tumor suppressor genes, and cytogenetic and epigenetic changes associated with the most common tumor types: mucoepidermoid carcinoma, adenoid cystic carcinoma, salivary duct carcinoma, mammary analogue secretory carcinoma, hyalinizing clear cell carcinoma, carcinoma ex pleomorphic adenoma, and acinic cell carcinoma. Recent insights into the pathogenesis of each cancer subtype have helped better define and classify these tumors. Further research in salivary gland cancers should focus on determining the key genes involved in the tumorigenesis of each distinct malignancy and identifying individualized chemotherapies directed at these targets.

Underrepresented in Medicine Student Perspectives on the Selection of a Summer Research Program.

OBJECTIVES: Many summer research programs (SRPs) for URiM students exist; however, only a few have been established by otolaryngology programs, who have a unique opportunity to provide a diverse experience. We sought to assess URiM undergraduate student perspectives on the most valuable program features that influence decision-making and how this might be useful to otolaryngology programs seeking to establish pathway programs. MATERIALS AND METHODS: An externally facing REDCap survey composed of 37 questions in scaled, multiple-choice, and open-ended form. The survey was delivered to applicants via email over two time periods in April 2021 and February 2022. All survey responses were analyzed using descriptive statistics and categorized according to demographic information, program features, and advertising mechanisms. RESULTS: Seventy-one percent of our applicants self-identified as URiM. Over 60% experienced financial hardship, and 31% experienced educational hardship. The single most important feature when selecting a summer research program (SRP) was access to mentorship followed by clinical shadowing and research opportunities. When program features were aggregated into groups, institutional features were the most important, followed closely by funding features. Finally, students prefer to learn about SRPs through their university, followed by social media, despite many students learning about our program through other means. CONCLUSIONS: Paid programs with effective advertising, research, mentoring, and clinical shadowing are highly valued by URiM undergraduate students. Understanding student perspectives is critical for programs aiming to address the "leaky pipeline" while being deliberate in their support of underrepresented students.

Addressing positive multi-cancer early detection tests in head and neck Surgery: Experience with head and neck work up for high-risk referrals.

OBJECTIVES: Blood-based multi-cancer early detection (MCED) tests are now commercially available. However, there are currently no consensus guidelines available for head and neck cancer (HNC) providers to direct work up or surveillance for patients with a positive MCED test. We seek to describe cases of patients with positive MCED tests suggesting HNC and provide insights for their evaluation. METHODS: Retrospective chart review of patients referred to Otolaryngology with an MCED result suggesting HNC. Patients enrolled in prospective MCED clinical trials were excluded. Cancer diagnoses were confirmed via frozen-section pathology. RESULTS: Five patients were included (mean age: 69.2 years, range 50-87; 4 male) with MCED-identified-high-risk for HNC or lymphoma. Only patient was symptomatic. After physical exam and follow-up head and neck imaging, circulating tumor HPV DNA testing, two patients were diagnosed with p16 + oropharyngeal squamous cell carcinomas and underwent appropriate therapy. A third patient had no evidence of head and neck cancer but was diagnosed with sarcoma of the thigh. The remaining two patients had no evidence of malignancy after in-depth workup. CONCLUSIONS: In this retrospective study, 2 of 5 patients referred to Otolaryngology with a positive MCED result were diagnosed with HPV + oropharyngeal squamous cell carcinoma. We recommend that positive HNC MCED work up include thorough head and neck examination with flexible laryngoscopy and focused CT or MRI imaging. Given the potential for inaccurate MCED tissue of origin classification, PET/CT may be useful in specific situations. For a patient with no cancer identified, development of clear guidelines is warranted.

Cancer in Patients With Incidental Asymmetric Oropharynx Positron Emission Tomography Uptake.

Importance: Asymmetric oropharynx uptake on positron emission tomography (PET)/computed tomography (CT) is a common incidental finding and often prompts otolaryngology referral to rule out malignancy; however, the true risk of malignancy based on this finding is unknown. Objective: To identify the incidence of oropharynx cancer in patients with incidental asymmetric oropharynx PET uptake. Design, Setting, and Participants: In this retrospective cohort study, patients 18 years and older undergoing PET/CT scans at Mayo Clinic between January 2001 and December 2018 were included. Patients with a history or pretest suspicion of oropharynx cancer were excluded. Data were analyzed from March 2021 to December 2023. Exposure: Blinded radiologic review of imaging studies, including measurement of maximum standardized uptake values (SUVmax) of the ipsilateral side of concern and contralateral side. Retrospective medical record review for associated clinical data. Main Outcomes and Measures: The primary study outcome was the incidence of oropharynx cancer diagnosis in patients with asymmetric oropharynx PET uptake. The primary outcome was formulated before data collection. Results: Of the 1854 patients identified with asymmetric oropharynx PET uptake, 327 (17.6%) met inclusion criteria. Of these, 173 (52.9%) were male, and the median (range) age was 65.0 (24.8-90.7) years. The mean (SD) follow-up interval was 52.1 (43.4) months. A total of 18 of 327 patients (5.5%) were newly diagnosed with oropharynx cancer. The most common diagnosis was squamous cell carcinoma (n = 9), followed by lymphoma (n = 8), and sarcoma (n = 1). Patients with an incidental diagnosis of oropharynx cancer had higher mean (SD) ipsilateral SUVmax (8.7 [3.7] vs 5.3 [1.9]) and SUVmax ratio (3.0 [1.6] vs 1.6 [0.6]) compared with patients with normal examination findings. SUVmax ratio and difference were found to be good discriminators of oropharynx cancer, with areas under the receiver operating characteristic curve of 86.3% (95% CI, 76.4-94.6) and 85.8% (95% CI, 74.8-94.6), respectively. Patients with a new diagnosis of oropharynx cancer were more likely to have a corresponding CT abnormality than those with normal examination findings (6 of 18 [33%] vs 24 of 295 [8.1%]). Patients with concerning lesions on oropharynx palpation by an otolaryngology health care professional were significantly more likely to be diagnosed with oropharynx cancer compared with patients with normal examination findings (odds ratio, 28.4; 95% CI, 6.6-145.8). Conclusions and Relevance: In this cohort study, while incidental asymmetric oropharynx PET uptake was common, a new diagnosis of oropharynx cancer was not and potentially results in a large volume of unnecessary referrals and work-up. Using SUVmax ratio, SUVmax difference, and CT correlation may increase the benefit of referral. Patients with a palpable oropharynx lesion and asymmetric oropharynx PET uptake should undergo confirmatory biopsy.

Creating an Undergraduate Research Program in Otolaryngology-Head and Neck Surgery (Oto-HNS) for Students Underrepresented in Medicine.

Objectives: To report implementation and outcomes associated with a novel paid Summer Undergraduate Research Education Program (SREP) over the first 2 years in an academic otolaryngology program recruiting students underrepresented in medicine (URiM). Methods: A 10-week program including a research bootcamp, curriculum, mentoring, and clinical shadowing was created. Grant funding to provide salary and support for transportation, conference attendance, and graduate school preparation or applications was procured. Primary objectives included (1) development of successful mentorship relationships; (2) increasing student-reported outcomes using pre- and post-program surveys to assess confidence, career planning, and overall satisfaction; (3) increasing exposure to medicine; (4) completion of an oral presentation; and (5) submission of a manuscript. Secondary objectives included abstract submission and completion of a graduate exam course or graduate school applications. Tertiary objectives included conference attendance and graduate school matriculation. Results: One hundred thirty-five total applications were reviewed (89 from year 1 and 46 from year 2). Twelve students were interviewed for 3 spots in year 1, while 11 students were interviewed for 6 spots in year 2 (median application score, 9.25 (range, 1-14); median interview score, 8.7 (range, 5.4-10); acceptance rate, 6.7% (9/135)). Students met all primary objectives. Mean program survey scores increased from 3.8 to 4.77 (p < 0.0001). Eight of nine students submitted an abstract to a national conference, with five of eight students accepted for a presentation. Two students were accepted into graduate school, while five others are on track for graduate school application. Conclusion: Identifying mentors, curriculum, and opportunities to meaningfully strengthen graduate school applications for URiM students through a clinically rigorous, financially supported, and research-focused summer program in an academic otolaryngology program is feasible and may be an effective means of increasing diversity in medicine and otolaryngology.

Mean Oral Cavity Organ-at-Risk Dose Predicts Opioid Use and Hospitalization during Radiotherapy for Patients with Head and Neck Tumors.

BACKGROUND: Approximately 75% of all head and neck cancer patients are treated with radiotherapy (RT). RT to the oral cavity results in acute and late adverse events which can be severe and detrimental to a patient's quality of life and function. The purpose of this study was to explore associations between RT dose to a defined oral cavity organ-at-risk (OAR) avoidance structure, provider- and patient-reported outcomes (PROs), opioid use, and hospitalization. METHODS: This was a retrospective analysis of prospectively obtained outcomes using multivariable modeling. The study included 196 patients treated with RT involving the oral cavity for a head and neck tumor. A defined oral cavity OAR avoidance structure was used in all patients for RT treatment planning. Validated PROs were collected prospectively. Opioid use and hospitalization were abstracted electronically from medical records. RESULTS: Multivariable modeling revealed the mean dose to the oral cavity OAR was significantly associated with opioid use (p = 0.0082) and hospitalization (p = 0.0356) during and within 30 days of completing RT. CONCLUSIONS: The findings of this study may be valuable in RT treatment planning for patients with tumors of the head and neck region to reduce the need for opioid use and hospitalization during treatment.

Differential roles of the dorsal and ventral hippocampus in predator odor contextual fear conditioning.

The study of fear memory is important for understanding various anxiety disorders in which patients experience persistent recollections of traumatic events. These memories often involve associations of contextual cues with aversive events; consequently, Pavlovian classical conditioning is commonly used to study contextual fear learning. The use of predator odor as a fearful stimulus in contextual fear conditioning has become increasingly important as an animal model of anxiety disorders. Innate fear responses to predator odors are well characterized and reliable; however, attempts to use these odors as unconditioned stimuli in fear conditioning paradigms have proven inconsistent. Here we characterize a contextual fear conditioning paradigm using coyote urine as the unconditioned stimulus. We found that contextual conditioning induced by exposure to coyote urine produces long-term freezing, a stereotypic response to fear observed in mice. This paradigm is context-specific and parallels shock-induced contextual conditioning in that it is responsive to extinction training and manipulations of predator odor intensity. Region-specific lesions of the dorsal and ventral hippocampus indicate that both areas are independently required for the long-term expression of learned fear. These results in conjunction with c-fos immunostaining data suggest that while both the dorsal and ventral hippocampus are required for forming a contextual representation, the ventral region also modulates defensive behaviors associated with predators. This study provides information about the individual contributions of the dorsal and ventral hippocampus to ethologically relevant fear learning.

Predictive Value of Preresidency Academic Metrics on Resident Publication Potential.

Objective: Otolaryngology residency is highly competitive, and applicant academic metrics are scrutinized. The predictive value of preresidency academic metrics on applicants' future research productivity and career aspirations remains largely undefined. Study Design: Retrospective cohort study. Setting: Academic otolaryngology department, 2014 to 2015. Methods: Applicant demographics, publication history, and United States Medical Licensing Examination (USMLE) scores were downloaded from Electronic Residency Application Service archives. Publications during residency were tallied from all PubMed articles indexed between July 1, 2015 and June 30, 2020. Postresidency career paths were examined by 2 investigators (D.J.C. and L.X.Y.) using Google searches with an emphasis on program websites, Doximity, and LinkedIn profiles. Associations with publication potential and postresidency positions were evaluated with Spearman rank correlation coefficients and Kruskal-Wallis, Wilcoxon rank sum, and χ 2 tests. Results: Of 321 applicants, 226 (70%) matched, and 205 (64%) completed residency by June 2020. Matched residents published a median of 4 (range: 0-41) manuscripts during residency. USMLE scores, Alpha Omega Alpha status, and the number of preresidency publications did not significantly correlate with publication potential during residency. The number of research experiences had a significant positive correlation with publications during residency (p < 0.001). Asian race (p = 0.002) and geographical region of residency (p < 0.001) also had significant associations with publication potential. Of the 205 graduates, 118 (58%) enrolled in fellowship. Age and female sex (74% vs 48%; p = 0.002) were the only factors significantly associated with pursuing a fellowship. Conclusion: In otolaryngology, not all preresidency academic metrics are associated with publication potential during residency or propensity for fellowship training. Programs should not use academic metrics alone to predict an applicant's future research productivity or career trajectory.

Racial disparities in surgical treatment of oropharyngeal cancer: A Surveillance, Epidemiology, and End Results review.

OBJECTIVES: Oropharyngeal squamous cell carcinoma (OPSCC) has been rising. This manuscript looks to explore racial disparities in the surgical management of OPSCC. METHODS: A cancer database was queried for patients with OPSCC diagnosed from 2004 to 2017. Univariate and multivariable logistic regressions were used to evaluate associations between patient race/ethnicity, surgical treatment, and reasons for lack of surgery. RESULTS: 37 306 (74.3%) patients did not undergo surgery, while 12 901 (25.7%) patients did. Non-Hispanic black (NHB) patients were less likely to undergo surgery than other races (17.9% vs. 26.5%; p < 0.0001). In clinical discussions, the Asian, Native American, Hawaiian, Pacific Islander (ANAHPI), and unknown race group was more likely to directly refuse surgery when recommended (2.5% vs. 1.5%; p = 0.015). CONCLUSION: Racial differences exist in treatment for OPSCC. NHB patients are less likely to actually undergo surgical management for OPSCC, while other patients are more likely to directly "refuse" surgery outright when offered.

Selective Deep Lobe Parotidectomy vs Total Parotidectomy for Patients With Benign Deep Lobe Parotid Tumors.

Importance: Limited literature exists on surgical outcomes after selective deep lobe parotidectomy (SDLP) with preservation of superficial lobe for patients with benign deep lobe tumors. Objective: To compare the following factors for SDLP vs total parotidectomy for patients with benign tumors in the deep lobe: postoperative complications, including facial nerve paresis or paralysis, Frey syndrome, first bite syndrome, cosmetic defect, sialocele formation, and wound infection; and tumor control and recurrence. Design, Setting, and Participants: This case series included 273 adults who underwent SDLP (n = 177) or total parotidectomy (n = 96) at a single tertiary care institution for benign parotid tumors located in the deep lobe or deep lobe and parapharynx from January 1, 2000, to December 31, 2020. Exposure: Selective deep lobe parotidectomy vs total parotidectomy. Main Outcomes and Measures: Incidence of postoperative complications and tumor recurrence. Results: Among 273 patients (SDLP, 177 [65%]; 122 women [69%]; median age at surgery, 58 years [IQR, 46-67 years]; total parotidectomy, 96 [35%]; 57 women [59%]; median age at surgery, 59 years [IQR, 40-68 years]), the most common tumor was pleomorphic adenoma (SDLP, 128 of 177 [72%]; total parotidectomy, 62 of 96 [65%]). An abdominal dermal fat graft was less commonly performed for patients who underwent SDLP than those who underwent total parotidectomy (2 of 177 [1%] vs 20 of 96 [21%]; difference, -20% [95% CI, -28% to -11%]). The rate of great auricular nerve preservation was higher in the SDLP group than in the total parotidectomy group (84 of 102 [82%] vs 20 of 34 [59%]; difference, 24% [95% CI, 5%-42%]). No meaningful difference in length of hospital stay was found. The percentage of patients with House-Brackmann grade I immediately after surgery was 48% (85 of 177) in the SDLP group and 21% (20 of 96) in the total parotidectomy group (difference, 28% [95% CI, 16%-40%]). There were no clinically meaningful differences in rates of hematoma, sialocele, seroma, ear numbness, wound infection, or unplanned return to emergency department or operating room. The SDLP group reported a lower rate of Frey syndrome than the total parotidectomy group (1 of 137 [1%] vs 12 of 78 [15%]; difference, -15% [95% CI, -23% to -7%]), as well as a lower rate of facial contour defect (28 of 162 [17%] vs 25 of 84 [30%]; difference, -13% [95% CI, -24% to -1%]) and a higher rate of first bite syndrome (34 of 148 [23%] vs 7 of 78 [9%]; difference, 14% [95% CI, 5%-23%]). The percentage of patients with House-Brackmann grade I at their first follow-up visit was 67% (118 of 177) in the SDLP group compared with 49% (47 of 96) in the total parotidectomy group (difference, 17% [95% CI, 4%-30%]). There was no clinically meaningful difference in House-Brackmann grade after 1 year. Conclusions and Relevance: Findings of this case series study suggest that SDLP can be considered an effective and even superior technique for management of benign tumors in the deep parotid lobe. Advantages associated with SDLP include reduction in need for reconstruction for facial contour defect and reduction in complications, such as immediate facial nerve weakness and Frey syndrome. The incidence of first bite syndrome was higher in the SDLP group. Tumor control was not compromised by SLDP.

Impact of Tumor-Infiltrating Lymphocytes on Disease Progression in Human Papillomavirus-Related Oropharyngeal Carcinoma.

OBJECTIVE: We aim to explore the prognostic value of tumor-infiltrating lymphocytes (TILs) in the primary tumor and metastatic lymph nodes of patients with HPV(+)OPSCC. We hypothesize that TILS density at both sites is associated with disease-free survival in HPV(+)OPSCC. STUDY DESIGN: Matched case-control study among HPV(+)OPSCC patients who underwent intent-to-cure surgery. Cases developed locoregional or distant recurrence. Controls were matched based on age, sex, pathologic T, N, and overall stage, year of surgery, type of adjuvant treatment received, and the Adult Comorbidity Evaluation-27 (ACE-27) score. SETTING: Single tertiary care center, May 2007 to December 2016. METHODS: Tumoral TILs (tTILs) density was defined as % TILs; stromal TILs (sTILs) density was defined as absent/sparse or moderate/dense crowding. Associations between TILs and time to disease progression were assessed using Cox regression models. RESULTS: Forty-four case-control pairs (N = 88) were included: 42 (48%) AJCC pStage I, 39 (44%) pStage II, and 7 (8%) pStage III. tTILs density ≥10% (hazard ratio [HR] 0.41, 95% confidence interval [CI] 0.17-0.99, p = .048) and a moderate/dense sTILs density (HR 0.21, 95% CI 0.06-0.75, p = .016) in the primary tumor were significantly associated with decreased risk of progression. TILs density in the lymph node was associated with decreased risk of progression but did not reach statistical significance. The tTILs and sTILs density correlated strongly between the primary tumor and lymph node. Concordance between the pathologists' was moderate (60%-70%). CONCLUSIONS: In HPV(+)OPSCC, a higher density of tumoral and stromal TILs in the primary tumor and possibly the lymph node may predict a lower risk of disease progression.
