Clinical and Biologic Characteristics and Outcomes in Young and Middle-Aged Patients With Laryngeal Cancer: A Retrospective Cohort Analysis.

OBJECTIVE: To describe the clinical and biologic characteristics and outcomes of young and middle-aged (YMA; <65 years) patients according to the presence or absence of traditional risk factors for laryngeal cancer. STUDY DESIGN: Retrospective cohort analysis. SETTING: Single-institution academic medical center. METHODS: Patients without a history of clinically significant tobacco use or heavy alcohol use were defined as "nontraditional": ≤5 pack-years, ≤5 years smoked, ≤14 alcoholic drinks per week, and ≥15-year interval from last tobacco abuse use to diagnosis. Remaining patients were categorized as "traditional." Select tumor samples were evaluated for bacterial and viral DNA by multiplex polymerase chain reaction. RESULTS: Seventy-eight YMA patients with primary laryngeal squamous cell carcinoma were identified, 23% (n = 18) of whom were nontraditional. Nontraditional patients were younger than traditional patients (median age, 51 vs 59 years; P < .001). Twenty-eight tumors were prospectively tested for human papillomavirus (HPV), and nontraditional patients were more likely to exhibit high-risk HPV (57% vs 5%, P < .01). Among 17 select tumors (nontraditional, n = 8; traditional, n = 9), 35% exhibited HPV16 (nontraditional, 63%; traditional, 11%; P = .05). Other viruses were identified but did not differ according to risk status: herpesviruses (40%) and Merkel cell polyomavirus (7%). Chlamydia, ß-HPV, and γ-HPV DNA was not detected in any samples. Median length of follow-up was 42 months. On adjusted analyses, nontraditional patients exhibited nonsignificantly improved overall survival (hazard ratio, 0.24 [95% CI, 0.03-1.82]; P = .17) and disease-free survival (hazard ratio, 0.34 [95% CI, 0.10-1.23]; P = .08) as compared with traditional patients. CONCLUSION: Almost one-quarter of YMA patients lacked characteristic risk factors for laryngeal squamous cell carcinoma, and their tumors exhibited a higher prevalence of high-risk HPV. The significance of HPV16 and other tumor viruses with outcomes in nontraditional patients should be evaluated further.

Oncologic outcomes in primary squamous cell carcinoma of the auricle: a retrospective cohort analysis.

PURPOSE: The prognostic significance of auricular location in cutaneous squamous cell carcinoma (cSCC) is controversial. We aimed to characterize risk factors for, and evaluate the cumulative incidence of, locoregional recurrence in a cohort of patients with primary auricular cSCC. METHODS: The study design was a single-institution retrospective cohort review from 1/2007 to 12/2016. RESULTS: Among 851 potentially eligible individuals, 178 patients with primary auricular cSCC met strict criteria for inclusion. Median follow-up was 32 months, 93% were AJCC 8th edition (AJCC8) stage I and 6% were AJCC8 stage II. Most underwent Mohs micrographic surgery (MMS; 97%) and the remainder underwent wide local excision ± parotidectomy ± neck dissection ± adjuvant therapy (3%). Recurrences occurred in seven patients (4%): six were local and one was regional. The 3-year cumulative incidence of local and regional recurrence for AJCC8 stage I-II tumors were 1% (95% CI 0-5%) and 0%, respectively. Among ten patients upstaged to pT3 disease who underwent MMS alone, none recurred locoregionally. Compared to their respective counterparts, advanced stage, PNI, and LVI associated with a significantly increased risk of locoregional recurrence. CONCLUSIONS: Our findings suggest that auricular location may not be a significant risk factor for cSCC staging systems. In the absence of other risk factors, unimodal therapy appears adequate for patients with primary, stage I-II auricular cSCC. The prognostic significance of pT3 auricular cSCC stage due to depth of invasion alone should be evaluated further.

Substance use and mental health burden in head and neck and other cancer survivors: A National Health Interview Survey analysis.

BACKGROUND: Tobacco dependence, alcohol abuse, depression, distress, and other adverse patient-level influences are common in head and neck cancer (HNC) survivors. Their interrelatedness and precise burden in comparison with survivors of other cancers are poorly understood. METHODS: National Health Interview Survey data from 1997 to 2016 were pooled. The prevalence of adverse patient-level influences among HNC survivors and matched survivors of other cancers were compared using descriptive statistics. Multivariable logistic regressions evaluating covariate associations with the primary study outcomes were performed. These included 1) current cigarette smoking and/or heavy alcohol use (>14 drinks per week) and 2) high mental health burden (severe psychological distress [Kessler Index ≥ 13] and/or frequent depressive/anxiety symptoms). RESULTS: In all, 918 HNC survivors and 3672 matched survivors of other cancers were identified. Compared with other cancer survivors, more HNC survivors were current smokers and/or heavy drinkers (24.6% [95% CI, 21.5%-27.7%] vs 18.0% [95% CI, 16.6%-19.4%]) and exhibited a high mental health burden (18.6% [95% CI, 15.7%-21.5%] vs 13.0% [95% CI, 11.7%-14.3%]). In multivariable analyses, 1) a high mental health burden predicted for smoking and/or heavy drinking (odds ratio [OR], 1.4; 95% CI, 1.0-1.9), and 2) current cigarette smoking predicted for a high mental health burden (OR, 1.7; 95% CI, 1.2-2.3). Furthermore, nonpartnered marital status and uninsured/Medicaid insurance status were significantly associated with both cigarette smoking and/or heavy alcohol use (ORs, 1.9 [95% CI, 1.4-2.5] and 1.5 [95% CI, 1.0-2.1], respectively) and a high mental health burden (ORs, 1.4 [95% CI, 1.1 -1.8] and 3.0 [95% CI, 2.2-4.2], respectively). CONCLUSIONS: Stakeholders should allocate greater supportive care resources to HNC survivors. The interdependence of substance abuse, adverse mental health symptoms, and other adverse patient-level influences requires development of novel, multimodal survivorship care interventions.

High-Risk Cutaneous Squamous Cell Carcinoma of the Head and Neck: A Clinical Review.

BACKGROUND: Given the rapidly evolving nature of the field, the current state of "high-risk" head and neck cutaneous squamous cell carcinoma (HNcSCC) is poorly characterized. METHODS: Narrative review of the epidemiology, diagnosis, workup, risk stratification, staging and treatment of high-risk HNcSCC. RESULTS: Clinical and pathologic risk factors for adverse HNcSCC outcomes are nuanced (e.g., immunosuppression and perineural invasion). Frequent changes in adverse prognosticators have outpaced population-based registries and the variables they track, restricting our understanding of the epidemiology of HNcSCC and inhibiting control of the disease. Current heterogeneous staging and risk stratification systems are largely derived from institutional data, compromising their external validity. In the absence of staging system consensus, tumor designations such as "high risk" and "advanced" are variably used and insufficiently precise to guide management. Evidence guiding treatment of high-risk HNcSCC with curative intent is also suboptimal. For patients with incurable disease, an array of trials are evaluating the impact of immunotherapy, targeted biologic therapy, and other novel agents. CONCLUSION: Population-based registries that broadly track updated, nuanced, adverse clinicopathologic risk factors, and outcomes are needed to guide development of improved staging systems. Design and development of randomized controlled trials (RCTs) in advanced-stage HNcSCC populations are needed to evaluate (1) observation, sentinel lymph node biopsy, or elective neck dissection for management of the cN0 neck, (2) indications for surgery plus adjuvant radiation versus adjuvant chemoradiation, and (3) the role of immunotherapy in treatment with curative intent. Considering these knowledge gaps, the authors explore a potential high-risk HNcSCC treatment framework.

Cutaneous Sarcomas.

Cutaneous sarcomas represent a rare group of tumors presenting in the head and neck. In this article, we discuss specific sarcoma tumor types and their presentation, pathogenesis, histologic findings, and management recommendations. Tumors to be reviewed include dermatofibrosarcoma protuberans, atypical fibroxanthoma, pleomorphic dermal sarcoma, cutaneous leiomyosarcoma, and angiosarcoma.

Head and neck oncology during the COVID-19 pandemic: Reconsidering traditional treatment paradigms in light of new surgical and other multilevel risks.

The COVID-19 pandemic demands reassessment of head and neck oncology treatment paradigms. Head and neck cancer (HNC) patients are generally at high-risk for COVID-19 infection and severe adverse outcomes. Further, there are new, multilevel COVID-19-specific risks to patients, surgeons, health care workers (HCWs), institutions and society. Urgent guidance in the delivery of safe, quality head and neck oncologic care is needed. Novel barriers to safe HNC surgery include: (1) imperfect presurgical screening for COVID-19; (2) prolonged SARS-CoV-2 aerosolization; (3) occurrence of multiple, potentially lengthy, aerosol generating procedures (AGPs) within a single surgery; (4) potential incompatibility of enhanced personal protective equipment (PPE) with routine operative equipment; (5) existential or anticipated PPE shortages. Additionally, novel, COVID-19-specific multilevel risks to HNC patients, HCWs and institutions, and society include: use of immunosuppressive therapy, nosocomial COVID-19 transmission, institutional COVID-19 outbreaks, and, at some locations, societal resource deficiencies requiring health care rationing. Traditional head and neck oncology doctrines require reassessment given the extraordinary COVID-19-specific risks of surgery. Emergent, comprehensive management of these novel, multilevel surgical risks are needed. Until these risks are managed, we temporarily favor nonsurgical therapy over surgery for most mucosal squamous cell carcinomas, wherein surgery and nonsurgical therapy are both first-line options. Where surgery is traditionally preferred, we recommend multidisciplinary evaluation of multilevel surgical-risks, discussion of possible alternative nonsurgical therapies and shared-decision-making with the patient. Where surgery remains indicated, we recommend judicious preoperative planning and development of COVID-19-specific perioperative protocols to maximize the safety and quality of surgical and oncologic care.

Comparison of Outcomes in Medical Therapy vs Surgical Intervention of Esophageal Foreign Bodies.

Objectives (1) Compare efficacy of primary medical therapy vs primary surgical intervention in patients with esophageal foreign bodies (EFBs). (2) Investigate variables that may predict successful outcomes in patients treated for EFBs. Study Design Case series with chart review. Setting Single-institution academic tertiary care medical center. Subjects and Methods Adult patients (older than 18 years) seen at the University of Michigan Emergency Department (ED) over an 8-year period with the diagnosis of EFBs (January 1, 2003, to December 31, 2011; N = 250). Decision was made by ED physicians whether to treat patients with first-line medical therapy vs surgical intervention. Pertinent clinical and demographic data were extracted from medical records and summarized by descriptive statistics. Results First-line treatment with surgical intervention (flexible or rigid esophagoscopy with foreign body removal) was much more likely to lead to resolution of symptoms than medical therapy (glucagon alone or in combination with other medical therapy) (98% vs 28%, P < .0001). When delivered within 12 hours of symptom onset, medical therapy was more likely to be successful (34% resolution vs 12% resolution, P < .01). There was no difference in complication rates for primary medical therapy vs surgical intervention (8% vs 8%). Conclusions Patients with EFBs are a commonly encountered consultation for both otolaryngologists and gastroenterologists. In these patients, first-line surgical intervention is superior to medical therapy and should not be avoided for a trial of medical therapy or concern for higher morbidity. Implementation of these findings has the ability to positively affect treatment patterns, outcomes, and patient quality of life.

Minimally Invasive Approach for Resection of Parameningeal Rhabdomyosarcoma.

Background About one-third of rhabdomyosarcomas arise in the head and neck, with parameningeal primaries accounting for half of these. Principles of management involve chemotherapy, radiation, or both, in addition to surgical biopsy, debulking, and complete or near-complete resection. In the head and neck, diagnostic biopsies have historically been performed without attempt at resection due to proximity to critical structures and cosmetic considerations. Methods Retrospective chart review of three cases of rhabdomyosarcoma at the cranial base managed through minimally invasive endoscopic surgical resection and adjuvant therapy. Results Three patients were identified as having undergone endoscopic surgical debulking or margin-negative resection of a rhabdomyosarcoma of the cranial base. Two of three patients had complete resection based on intraoperative margin control. All three patients underwent adjuvant therapy within 1 month of diagnosis. Follow-up time ranged from 5 months to 3 years with all patients disease-free at last follow-up. Conclusion Skull base surgeons should routinely be involved in multidisciplinary treatment planning for parameningeal rhabdomyosarcomas, as surgical options have evolved to allow for potential endoscopic resection with low morbidity and no or minimal delay in additional treatment options.

Identification of Targetable ERBB2 Aberrations in Head and Neck Squamous Cell Carcinoma.

IMPORTANCE: ERBB2 (formerly HER2) is an important drug target in breast cancer, where anti-ERBB2 therapy has been shown to lead to improvements in disease recurrence and overall survival. ERBB2 status in head and neck squamous cell carcinoma (HNSCC) has not been well studied. Identification of ERBB2-positive tumors and characterization of response to ERBB2 therapy could lead to targeted treatment options in HNSCC. OBJECTIVE: To identify ERBB2 aberrations in HNSCCs and investigate the potential for ERBB2-targeted therapy in HNSCCs. DESIGN, SETTING, AND PARTICIPANTS: A retrospective case series of patients with laryngeal (42 tumor specimens) and oral cavity (94 tumor specimens) SCC enrolled in the University of Michigan Head and Neck Specialized Program of Research Excellence was conducted. Publicly available sequencing data (The Cancer Genome Atlas), as well as data from other studies, were reviewed to identify additional mutations and overexpression in ERBB2 in HNSCC. Established HNSCC cell lines were used for follow-up in vitro analysis. The study was conducted from October 1, 2014, to August 30, 2015. INTERVENTIONS: With the use of targeted, amplicon-based sequencing with the Oncomine Cancer Panel, the copy number and mutation status of commonly altered genes in HNSCCs were assessed. Immunohistochemical staining was performed on tissue microarrays of HNSCCs to assess the expression of ERBB2. Western blotting for HNSCC cell line ERBB2 expression and cell survival assays after treatment with ERBB2 inhibitors were performed. MAIN OUTCOMES AND MEASURES: The prevalence of ERBB2 genetic aberrations and ERBB2 overexpression in laryngeal and oral cavity SCCs, prevalence of ERBB2 aberrations in HNSCC in The Cancer Genome Atlas, ERBB2 protein expression in HNSCC cell lines, and response of HNSCC cell lines to targeted ERBB2 inhibitors. RESULTS: Of the 42 laryngeal SCC samples screened by targeted sequencing, 4 (10%) were positive for ERBB2 amplification. Two of these samples showed ERBB2 overexpression on immunohistochemistry. Two of the 94 oral cavity SCC samples (2%) were positive for ERBB2 on immunohistochemistry. Analysis of 288 patients from publicly available HNSCC sequencing data revealed 9 amplifications (3%) in ERBB2. Protein expression was variable across HNSCC cell lines, and a subset of these cell lines showed responsiveness to anti-ERBB2 therapy. CONCLUSIONS AND RELEVANCE: ERBB2 aberrations were identified in a subset of HNSCCs. These tumors may be responsive to targeted therapy against ERBB2. Screening for ERBB2 aberrations and applying targeted therapy in ERBB2-positive patients may be useful in personalized therapy trials, particularly in patients who are refractory to current treatment paradigms.

Fibroblast growth factor family aberrations as a putative driver of head and neck squamous cell carcinoma in an epidemiologically low-risk patient as defined by targeted sequencing.

BACKGROUND: Targeted sequencing of patients with epidemiologically low-risk (ELR) head and neck squamous cell carcinoma (HNSCC) could help identify novel drivers or lost suppressors leading to precision medicine protocols and improved survival rates. METHODS: A patient with ELR-HNSCC was selected for targeted sequencing. We then assessed next generation sequencing cohorts from the Oncomine Powertool Database, which contains pan-cancer data from The Cancer Genome Atlas (TCGA). RESULTS: Targeted sequencing revealed fibroblast growth factor receptor-1 (FGFR1) amplifications as a putative driver of the patient's tumor. Patients with HNSCC from TCGA data demonstrated fibroblast growth factor (FGF) family mutations, rearrangements, or amplifications in over 35% of HNSCC cases, with a statistically significant higher frequency in African American populations. FGF alterations were unique from activating phosphatidylinositol 3-kinase (PIK3CA) mutations. CONCLUSION: Together, these data suggest that FGF signaling may be critical for a subset of patients with HNSCC independent of other known pathways and provides rationale for leveraging patients with ELR-HNSCC to define molecular subsets of high-risk HNSCC. © 2016 Wiley Periodicals, Inc.

A lean neck mass clinic model: Adding value to care.

OBJECTIVES/HYPOTHESIS: To demonstrate that ultrasound-guided fine needle aspiration (USFNA) with on-site cytopathologic analysis eliminates unnecessary diagnostic testing, return visits, and repeat procedures and optimizes quality of care. STUDY DESIGN: Retrospective cohort. METHODS: Sixty-one new patients (28 female; 33 male; age range=19-85 years) were seen in our dedicated neck mass clinic over a 1-year period. All patients underwent USFNA of masses located in neck levels I-VI (n=40), parotid gland (n=20), or parapharyngeal space (n=1). Each patient underwent two USFNA passes followed by on-site cytopathologic analysis with additional passes if required for diagnosis. RESULTS: Diagnosis was made in 93.4% (n=57) of patients, allowing for counseling and treatment planning at the first visit. To obtain a diagnosis, more than half (57.4%, n=35) of our patients required additional passes, which implies that they would have required an additional visit without on-site cytopathologic analysis. Treatment included observation in 42.6% (n=26) of patients, surgery in 32.8 % (n=20) of patients, and nonsurgical treatment (chemotherapy, radiation, other) in 24.6% (n=15) of patients. The average time from check-in to checkout including the clinic visit, biopsy, and treatment counseling was 103 minutes, and the average round trip mileage traveled per patient was 127.6 miles. CONCLUSIONS: The adult neck mass is a commonly encountered scenario in otolaryngology. For the patient, this can be a stressful situation in which timely and accurate diagnosis is critical. A dedicated lean neck mass clinic model with USFNA and on-site cytopathologic analysis can be both an efficient part of one's practice and a valuable addition to patient care. LEVEL OF EVIDENCE: 4.

Infantile Frey's syndrome.

Frey's syndrome in children is rare and often erroneously attributed to food allergy. Here we describe a case of Frey's syndrome in an infant and provide a review of the literature. Awareness of this condition is important for the Otolaryngologist in order to avoid unnecessary medical costs and procedures and provide reassurance to both parents and primary care providers in the setting of this benign condition.
