Objectives To identify the differences in sensitivity and accuracy between ultrasound‐guided and palpation‐guided fine needle aspirations (FNA) of suspicious lymph nodes in patients with human papillomavirus (HPV) (+) oropharyngeal squamous cell carcinoma (OPSCC). Additional objectives included identifying patient specific factors affecting biopsy accuracy and evaluating potential differences in accuracy between fine and core needle biopsies. Study Design Retrospective chart review. Materials and Methods A retrospective study of diagnostic sensitivity was completed at a single tertiary care center between 1/1/2006–12/31/2016. Participants included patients who underwent pretreatment FNA biopsy with HPV(+)OPSCC confirmed pathologically following neck dissection or excisional lymph node biopsy. A true positive (TP) on FNA biopsy was defined as an FNA biopsy concerning for squamous cell carcinoma (SCC) that was confirmed on excisional biopsy or neck dissection. A false negative (FN) was defined as a negative FNA but metastatic disease identified on excisional biopsy or neck dissection. Sensitivity was calculated as TPs/(TPs + FNs). Sensitivity was compared among techniques using chi‐square and Fisher exact tests. Results A total of 209 FNA biopsies among 198 patients were included in the study, including 31 (15%) palpation‐guided FNAs, 160 (77%) ultrasound‐guided FNAs, and 18 (9%) ultrasound‐guided FNA + core biopsies. Sensitivity was significantly different among palpation‐guided FNA, ultrasound‐guided FNA, and ultrasound‐guided FNA + core biopsies (48% vs. 83% vs. 94%, respectively; P < .001) but there was no significant difference in sensitivity between ultrasound‐guided FNA versus ultrasound‐guided FNA + core biopsies ( P = .31). Conclusion The use of ultrasound guidance in FNA biopsies of nodal metastases in HPV(+)OPSCC improves sensitivity compared to palpation guidance alone. Ultrasound guided biopsies are preferred in patients with suspected nodal metastasis from HPV(+)OPSCC. Level of Evidence 3 Laryngoscope , 132:2396–2402, 2022

ObjectiveWe present the outcomes for patients with idiopathic subglottic stenosis (iSGS) following their first carbon dioxide laser wedge excision (LWE) procedure, additionally examining the effect of compliance with adjuvant medical therapy (triple therapy) after the operation.Study DesignRetrospective chart review.SettingTertiary center.MethodsA retrospective review was performed on 183 patients with iSGS following their first LWE and their compliance to adjuvant medical therapy (inhaled corticosteroid, proton pump inhibitor, trimethoprim‐sulfamethoxazole) following the operation, with all reviewed to December 31, 2020. The primary outcome variable was median time to recurrence (MTR). Patients were stratified by whether the LWE was their first operation (LWE primary or secondary), by compliance to triple therapy, and by compliance with trimethoprim‐sulfamethoxazole. Kaplan‐Meier analysis and Cox proportional hazards were used to evaluate the MTR across the stratifications.ResultsAn overall 113 patients underwent their first LWE, while 70 received the procedure after having undergone 1 to 13 procedures. The MTR between LWE primary and secondary was 4.6 and 2.9 years, respectively. Adjusted Cox proportional hazards comparing these 2 groups revealed the number of prior operations to be a confounding variable. A statistically increased MTR was demonstrated with greater degrees of medical compliance.ConclusionLWE conferred an MTR of 4.1 years in the iSGS cohort. The number of prior procedures preceding LWE behaved as a confounding variable. Patients who were completely or partially compliant to triple therapy appear to demonstrate increased intervals prior to recurrence.

ObjectiveInvestigate oncologic and functional outcomes associated with transhyoid and lateral pharyngotomy (transpharyngeal) approaches in the treatment of oropharyngeal squamous cell carcinoma (OPSCC).Study DesignRetrospective review.SettingSingle institution (tertiary care center).MethodsThis is a retrospective case series of patients with OPSCC undergoing transpharyngeal resection from 1990 to 2017 at Mayo Clinic. Oncologic outcomes, postoperative complications, objective swallowing data, and rates of tracheostomy and percutaneous gastrostomy tube dependence were recorded.ResultsOf 83 patients meeting inclusion criteria, 56 (68%) were human papillomavirus positive. Overall survival rates at 5 and 10 years following surgery were 85% and 80%, respectively. Cancer‐specific survival rates at these same time points were 90% and 88%. Following treatment, 35 of 49 patients (71%) had a Functional Oral Intake Scale score ≥5, indicating total oral intake of multiple consistencies; 79 of 82 (96%) were without tracheostomy or laryngectomy; and 71 of 81 (88%) were on a full oral diet.ConclusionTranspharyngeal approaches provide adequate functional and oncologic outcomes in the majority of patients with OPSCC. These results may have important implications for patients who are not candidates for, or are unwilling to undergo, nonoperative therapy or for those without access to radiation therapy.

Abstract Introduction Zenker diverticulum (ZD) usually affects adults after the 7th decade of life. Treatment for ZD is indicated for all symptomatic patients, but some patients prefer to defer surgical treatment until symptoms get worse and decrease their quality of life. Objective To evaluate the association of the preoperative symptoms in ZD patients with the size of the ZD. Methods A retrospective study design. Electronic medical records were used to identify patients diagnosed with ZD and treated over 11 years. Data collection included the chief complaints and symptoms, medical history, and findings on radiologic swallow evaluations of the patients. The diverticulum size was stratified into 3 groups: small (< 1 cm), moderate (1–3 cm), and large (> 3 cm). Results A total of 165 patients were enrolled and stratified by diverticulum size (48 small, 67 medium, and 50 large). Dysphagia, cough, and regurgitation were the most prevalent symptoms. Dysphonia was more frequent among patients with a small pouch. Logistic regression analysis showed that dysphagia and choking were associated with large and medium diverticulum size (p < 0.05). Additionally, dysphonia was significantly associated with the presence of a small-sized ZD (p < 0.04). Conclusion Upper gastrointestinal symptoms such as dysphagia and choking may be associated with a ZD > 1 cm and should always be evaluated. Additionally, the presence of dysphonia was found to be correlated with a ZD < 1 cm, suggesting that a prompt and appropriate fluoroscopic evaluation must be considered in those patients in whom no other clear cause of dysphonia is evident.

ObjectiveTo describe and compare rates of metachronous and synchronous second primaries of the contralateral tonsil in patients with primary HPV(+) tonsillar squamous cell carcinoma (SCC).Study DesignRetrospective cohort study.Materials and MethodsThis is a single tertiary care center retrospective case series, from 2006 to 2019, of HPV(+) tonsillar SCC patients who underwent primary surgical resection with unilateral wide‐field tonsillectomy or bilateral tonsillectomy for diagnostic or therapeutic purposes. A metachronous second primary is one diagnosed >6 months after completion of surgical treatment. A synchronous second primary is one diagnosed during bilateral tonsillectomy for unilateral HPV(+) tonsillar SCC. Rates of second primary and patient characteristics were compared using chi‐square tests.ResultsAbout 303 patients underwent unilateral surgical resection +/− adjuvant therapy for HPV(+) tonsillar SCC. One (0.3%) developed a metachronous second primary in the contralateral tonsil 11.9 years following treatment. Fifty‐seven patients with HPV(+) tonsillar SCC underwent bilateral tonsillectomy, and 37/57 (65%) had no clinical signs for contralateral disease. Of these, only 1/37 (2.7%) was incidentally found to have a synchronous second primary. Twenty patients underwent bilateral tonsillectomy due to clinical concern for contralateral disease. Of these, 3/20 (15%) were found to have a synchronous HPV(+) SCC in the contralateral tonsil.ConclusionsThe prevalence of metachronous second primary after appropriate treatment of HPV(+) tonsillar SCC is very low (0.3%) and so is the chance of incidentally discovering a synchronous second primary during bilateral tonsillectomy (2.7%). We do not recommend bilateral tonsillectomy as a part of the routine algorithm in the surgical management of these patients.Level of Evidence3 Laryngoscope, 132:332–338, 2022

AbstractBackgroundParotid gland mucoepidermoid carcinoma (MEC) has published five‐year cancer‐specific survival (CSS) rates of 77%–97%, with variance related to grade.MethodsPatients receiving primary surgery for parotid gland MEC from 1995 to 2014 at a tertiary medical center underwent clinical review, histopathologic review, and cytogenetic analysis. Survival outcomes were evaluated.ResultsAmong 58 patients, T/N/M classification was as follows: T1 in 35 patients, T2 in 14, T4a in 9, N0 in 53, N1 in 2, N2b in 3. Histologic grade was low in 27, intermediate in 17, and high in 12 patients with 98% MAML2 positivity. All patients underwent parotidectomy, and seven patients received adjuvant radiation therapy. CSS was 100% at 5 years and 94.1% at 10 and 15 years. Two patients experienced locoregional recurrence.ConclusionsTreatment with adequate surgical resection and adjuvant radiation therapy for high‐grade or advanced‐stage tumors yields excellent survival, independent of clinical stage or pathologic grade.

Abstract Background To determine whether virtual surgical planning and three‐dimensional printed cutting guides (3D/VSP) improved radiographic bone union compared to conventional methods (CM) in fibula free flap (FFF) reconstruction of the mandibles. Methods Retrospective study from the years 2000–2018 at a tertiary hospital. Osseous union was evaluated by a radiologist blinded to each patient's treatment. Results Two hundred sixty patients who underwent FFF tissue transfer, 28 with VSP and 3D cutting guides. Bony union was not achieved in 46 (20%) patients who underwent CM compared to 1 (4%) of patients with VSP and guides ( p = 0.036). FFF complication was significantly higher in CM with 87 patients (38%) compared to three patients (11%) in 3D/VSP ( p = 0.005). Median time to bony union for patients who underwent CM was 1.4 years compared to 0.8 years in 3D/VSP. Conclusions 3D/VSP reduced the rate of radiographic nonunion and flap‐related complications in FFF reconstruction for mandibular defects.

ObjectiveDiagnostic delay in human papillomavirus–associated oropharynx squamous cell carcinoma (HPV(+)OPSCC) is common due to nonspecific symptoms. We aim to describe the disease burden and oncologic outcomes of patients with HPV(+)OPSCC diagnosed >12 months after symptom onset.Study DesignThis is a retrospective cohort study of HPV(+)OPSCC patients receiving intent‐to‐cure treatment (including surgery ± adjuvant therapy or primary chemoradiation).Setting2006‐2016, tertiary care center.MethodsTumor stage was compared between patients with and without delayed diagnosis using χ2 tests. Kaplan‐Meier survival analysis with univariate and multivariable Cox regressions were used to determine the effect of diagnostic delay on oncologic outcomes.ResultsIn total, 664 patients were included. Compared to patients diagnosed <12 months from symptom onset (n = 601), those diagnosed at >12 months (n = 63) were more likely to have T4 disease and higher overall American Joint Committee on Cancer (AJCC) clinical stage at presentation (P <. 01 for both). At 5 years, rates of overall survival, cancer‐specific survival, progression‐free survival, and distant metastases–free survival in the delayed diagnosis cohort were 80%, 90%, 80%, and 89%, respectively. A >12‐month delay in diagnosis did not significantly impact overall survival (adjusted hazard ratio [aHR], 1.16; 95% CI, 0.58‐2.31), cancer‐specific survival (aHR, 0.83; 95% CI, 0.29‐2.39), progression‐free survival (aHR, 1.15; 95% CI, 0.56‐2.37), or distant metastases–free survival (aHR, 1.00; 95% CI, 0.42‐2.40) after adjusting for age, sex, and clinical AJCC stage (P >. 05 for all).ConclusionsDelayed diagnosis of HPV(+)OPSCC is associated with greater burden of disease at presentation, but oncologic outcomes remain favorable across treatment modalities. When appropriate, intent‐to‐cure therapy should be pursued despite diagnostic delay.Level of EvidenceLevel III.

Background: Anaplastic thyroid cancer (ATC) is a rare but highly lethal form of thyroid cancer. Since the guidelines for the management of ATC by the American Thyroid Association were first published in 2012, significant clinical and scientific advances have occurred in the field. The aim of these guidelines is to inform clinicians, patients, and researchers on published evidence relating to the diagnosis and management of ATC. Methods: The specific clinical questions and topics addressed in these guidelines were based on prior versions of the guidelines, stakeholder input, and input of the Task Force members (authors of the guideline). Relevant literature was reviewed, including serial PubMed searches supplemented with additional articles. The American College of Physicians Guideline Grading System was used for critical appraisal of evidence and grading strength of recommendations. Results: The guidelines include the diagnosis, initial evaluation, establishment of treatment goals, approaches to locoregional disease (surgery, radiotherapy, targeted/systemic therapy, supportive care during active therapy), approaches to advanced/metastatic disease, palliative care options, surveillance and long-term monitoring, and ethical issues, including end of life. The guidelines include 31 recommendations and 16 good practice statements. Conclusions: We have developed evidence-based recommendations to inform clinical decision-making in the management of ATC. While all care must be individualized, such recommendations provide, in our opinion, optimal care paradigms for patients with ATC.
