ABSTRACT

BACKGROUND: Patients with oropharyngeal squamous cell carcinoma (OPSCC) treated with radiation-based therapy suffer from short- and long-term toxicities that affect quality of life (QOL). Transoral robotic surgery (TORS) has an established role in the management of early OPSCC but adjuvant treatment is often indicated postoperatively due to the high incidence of nodal metastasis associated with advanced human papillomavirus (HPV)-related OPSCC. To overcome the need for adjuvant radiation therapy (RT), neoadjuvant chemotherapy followed by TORS and neck dissection (ND) is proposed. This study aimed to assess if QOL in HPV-associated OPSCC receiving neoadjuvant chemotherapy followed by TORS and ND returns to baseline within 12 months of completing treatment. METHODS: A 12 month longitudinal study was carried out at McGill University Health Centre in Montreal, Canada, among a convenience sample of patients with American Joint Committee on Cancer Seventh Edition stage III and IVa HPV-related OPSCC who were treated with neoadjuvant chemotherapy followed by TORS and ND. QOL data were obtained pretreatment and at 1, 3, 6, and 12 months following treatment completion using the European Organisation for Research and Treatment of Cancer Core and Head and Neck extension modules. Paired t tests and mixed models for repeated measures analysis were used to assess changes in QOL from baseline to 12 months postoperatively and over time, respectively. RESULTS: Nineteen of 23 patients (median age 58 years) who received the study treatment fulfilled the eligibility criteria. OPSCC subsites were palatine tonsil (n = 12) and base of tongue (n = 7). All 19 patients were treated per protocol and none required adjuvant RT as per pathology review and protocol requirements at a postoperative multidisciplinary team tumor board discussion. No significant differences were found when comparing 12 month QOL follow-up scores to pretreatment scores in measures that would likely be affected by RT [eg, swallowing (P = .7), social eating (P = .8), xerostomia (P = .9)]. CONCLUSION: In HPV-related OPSCC, neoadjuvant chemotherapy followed by TORS and ND as definitive treatment is associated with excellent QOL outcomes. Postoperative QOL scores returned to baseline by 3 months and were maintained for all measures, indicating a return to normal function.

ABSTRACT

Importance: Efforts are underway to deintensified treatment protocols for patients with human papillomavirus virus-associated oropharyngeal squamous cell carcinoma (HPV-OPSCC) to achieve similar excellent oncologic outcomes while reducing treatment-related adverse effects. Transoral robotic surgery (TORS) as primary treatment often requires adjuvant therapy due to the high incidence of nodal metastasis. Treatment with neoadjuvant chemotherapy followed by TORS and neck dissection (NECTORS), reserving radiation therapy for salvage, yields excellent oncologic outcomes. Objective: To assess patient-reported quality of life (QOL) and functional outcomes among patients with HPV-OPSCC who undergo NECTORS. Design, Settings, and Participants: This was a multicenter prospective cohort study of patients with HPV-OPSCC treated with the NECTORS protocol in 2017 to 2022. Consecutive patients with stage III or IVa HPV-OPSCC treated with NECTORS in 2017 to 2022 who had completed the primary QOL questionnaire at baseline and at least once during the 24-month follow-up period were included. Ninety-four patients were eligible, and 67 were included in the analyses. Outcome Measures: QOL questionnaires at baseline, and at month 1, 3, 6, 12, 18, and 24 posttreatment. Global score on the 30-item European Organization for Research and Treatment of Cancer Core quality of life questionnaire (EORTC QLQ-C30) was the primary outcome; the head and neck extension module (EORTC QLQ-HN35); the MD Anderson Dysphagia Inventory for dysphagia-related QOL; and the Decision Regret Scale were also used. Paired t tests assessed change between the baseline and 12- or 24-month patient-reported outcomes. Results: Among the study population of 67 patients (median [range] age, 63 [58-67] years; 54 [80.6%] male) with HPV-OPSCC, the most frequent cancer subsites were palatine tonsil (41 [61%]) and base of tongue (26 [39%]); none required adjuvant RT. Global QOL at 24 months improved compared with baseline (mean difference, 9.49; 95% CI, 2.45 to 16.53). All EORTC QLQ-C30 functional scores returned to baseline or improved within 3 to 6 months posttreatment and remained stable at 24 months. EORTC QLQ-HN35 symptom scale scores improved or were stable at 24 months. The MD Anderson Dysphagia Inventory scores demonstrated no significant difference between baseline and month 12 for global scores (mean difference, 6.15; 95% CI, -4.18 to 16.49) and composite scores (mean difference, 2.73; 95% CI, -1.62 to 7.09). Median (range) score on the Decision Regret Scale was 5 of 100 (0-30), representing mild overall regret. Conclusion and Relevance: The findings of this multicenter cohort study indicate that use of the NECTORS protocol is associated with excellent QOL outcomes. QOL measures returned to baseline levels or were better than baseline, which represents positive outcomes for patients with HPV-OPSCC who undergo this treatment regimen.

ABSTRACT

OBJECTIVE/HYPOTHESIS: To review the imaging findings of laryngeal amyloidosis and to identify radiological findings suggestive of this disease. STUDY DESIGN: Retrospective case series. METHODS: A retrospective chart review of patients with pathologically confirmed laryngeal amyloidosis was performed from 2009 to 2022. Clinical and demographic factors were collected. A fellowship-trained head and neck radiologist reviewed all computed tomography (CT) scans and magnetic resonance imaging (MRI) findings within this cohort. RESULTS: 12 patients were identified and a total of 36 imaging studies analyzed. Localized amyloidosis was found in the supraglottic region (n = 6), glottic region (n = 7), and subglottic region (n = 5); six patients had disease spanning two subsites. The most common finding on the CT scan was a homogeneous and well-defined submucosal soft tissue mass. Punctate calcifications were present in three cases. The presence of contrast enhancement was identified in the majority of patients who underwent MRI (4/5). MRI showed consistent signal intensity, hypointense, or isointense on both T1-weighted and T2-weighted images. Diffusion-weighted sequences were obtained in every patient and did not demonstrate diffusion restriction. CONCLUSION: This is the largest series searching for unifying imaging characteristics of laryngeal amyloidosis. This research suggests that characteristics from CT and MR provide both similar and unique features of laryngeal amyloidosis on imaging. Both modalities identify a submucosal mass. CT is the preferred modality to demonstrate punctate calcifications, while MRI identifies enhancement and altered signal characteristics. The main benefit of serial imaging is the correlation with patient symptoms, identification of the extent of disease, and assisting in delineating appropriate timing for surgery.

ABSTRACT

The incidence of all head and neck malignancies is rising worldwide, with carcinoma of the larynx constituting approximately 1% of all cancers. Early glottic cancer responds quite favorably to surgical intervention due to its early presentation, coupled with the low rate of regional and distant metastases. This article focuses on various approaches to the surgical treatment of early glottic cancer. Details include the clinical and radiological evaluation of laryngeal cancer, the goals of treatment, current surgical options for early disease, approach to surgical resection margins and management of nodal disease, and complications associated with each treatment modality.

ABSTRACT

Background: Oropharyngeal squamous cell carcinoma (OPSCC) patients are burdened by the effect of the disease process and treatment toxicities on organs important in everyday activities, such as breathing, speaking, eating, and drinking. There is a rise in OPSCC due to human papilloma virus (HPV)-associated OPSCC, affecting younger and healthier patients and with a better overall prognosis. Emphasis must be shared between oncologic outcomes and the effects on quality of life. While there have been efforts to study global and physical quality of life, the impact on psychosocial quality of life has not yet been specifically reviewed. Methods: A scoping review methodology was employed to explore the emotional, social, and mental quality of life in OPSCC patients and determine the impact of HPV status or treatment modalities. Results: Eighty-seven full-text articles were evaluated for eligibility. Fifteen articles met final inclusion criteria. The majority of the studies were conducted in the United States (n = 10) and study methodology was divided between cross-sectional (n = 6), prospective (n = 5), and retrospective studies (n = 4). Four psychosocial quality of life themes were explored: the impact on mental health and emotional wellbeing, social wellbeing and function, stress, and relationship and sexual behavior. Eighteen different patient-reported outcome measures were used, including both general head and neck oncology questionnaires and symptom-specific surveys. Conclusion: There is a paucity of research regarding the effect of OPSCC on patients' psychosocial quality of life. Learning more about this component of quality of life can guide outreach programs and multidisciplinary involvement in improving patient care.

ABSTRACT

Importance: Obesity has traditionally been described as a relative contraindication to percutaneous dilatational tracheostomy (PDT). Increased familiarity with the technique and use of bronchoscopy or real-time ultrasonography to enhance visualization have led many practitioners to expand the indication for PDT to patients historically deemed to have high risk of perioperative complications. Objective: To assess the reported complication rate of PDT in critically ill adults with obesity and compare it with that of open surgical tracheostomies (OSTs) in this patient population and with that of PDT in their counterparts without obesity. Data Sources: In this systematic review and meta-analysis, Ovid MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials were searched from January 1, 2000, to March 1, 2022. Key terms related to percutaneous tracheostomy and obesity were included. Study Selection: Original investigations of critically ill adult patients (age ≥18 years) with obesity who underwent PDT that reported at least 1 complication of interest were included. Case reports or series with fewer than 5 patients were excluded, as were studies in a language other than English or French. Data Extraction and Synthesis: Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) and Meta-analysis of Observational Studies in Epidemiology (MOOSE) were used, with independent extraction by multiple observers. Frequencies were reported for all dichotomous variables. Relative risks for complications were calculated using both fixed-effects and random-effects models in the meta-analysis. Main Outcomes and Measures: Main outcomes included mortality directly associated with the procedure, conversion to OST, and complications associated with the procedure (subclassified into life-threatening or non-life-threatening adverse events). Results: Eighteen studies were included in the systematic review, comprising 1355 patients with obesity who underwent PDT. The PDT-related complication rate was 16.6% among patients with obesity overall (791 patients, 17 studies), most of which were non-life-threatening. Only 0.6% of cases (8 of 1314 patients, 17 studies) were aborted or converted to an OST. A meta-analysis of 12 studies (N = 4212; 1078 with obesity and 3134 without obesity) showed that patients with obesity had a higher rate of complications associated with PDT compared with their counterparts without obesity (risk ratio, 1.78; 95% CI, 1.38-2.28). A single study compared PDT with OST directly for critically ill adults with obesity; thus, the intended meta-analysis could not be performed in this subgroup. Conclusions and Relevance: The findings suggest that the rate of complications of PDT is low in critically ill individuals with obesity, although the risk of complications may be higher than in individuals without obesity.

ABSTRACT

OBJECTIVES: To conduct a scoping review of the literature on psychological interventions directed to identify primary prevention strategies for depression among adult head and neck cancer (HNC) patients. METHODS: Systematic searches were conducted following Preferred Reporting Items for Systematic Reviews and Meta-Analysis Extension for Scoping Review including relevant studies within the PubMed, PsycINFO, and EMBASE databases. Two authors independently screened the searches and reviewed the included articles according to the predetermined eligibility criteria based on the PICOS format. Studies included subjects with previous or current diagnosis of depression were excluded. The risk of bias assessment of these trials was conducted following the Cochrane tool for assessing the risk of bias in randomized trials. The search was repeated prior to submission to ensure all current articles meeting criteria were included. RESULTS: The search yielded 875 studies. The title and abstract screen, followed by the review of full texts identified five articles that met inclusion criteria. Four were randomized controlled trials (RCT) and the fifth was a non-randomized but controlled study. Different psychosocial interventions were used, including psycho-educational interventions, psychosocial counseling, and pharmacotherapy. All studies established the diagnosis of depression or screened for the diagnosis using standardized psychiatric assessment tools, either Diagnostic and Statistical Manual of Mental Disorders criteria or validated patient reported outcome measures. The average follow-up periods after intervention was 9.8 months. There was a significant decrease in the incidence of depression or depressive symptoms favoring the intervention group in three out of the five studies that were included. CONCLUSION: Psychological interventions identified thus far studying primary prevention of depression in HNC patients show promising results. However, the paucity of data and heterogeneity of the interventions challenges the ability to compare the prevention modalities and outcomes. Future well-designed RCTs with large sample sizes are recommended to better conclude a result of effectiveness.

ABSTRACT

SIGNIFICANCE STATEMENT: We present the rare case of a nasal lobular capillary hemangioma with bony erosion atypically localized to the left piriform aperture. This fast-growing lesion caused both physical and emotional distress due to recurrent epistaxis and prominent esthetic deformity evidenced by a large nasal growth. While the final diagnosis was benign, the clinical and radiological findings caused concern. This case serves as a reminder that prompt referral, work-up, and diagnosis are essential to optimize patient care.

ABSTRACT

Prostate cancer metastases involving the orbit and/or paranasal sinuses represent a rare oncological presentation. Patients can have a myriad of symptoms such as proptosis, periorbital swelling, blurry vision, rhinorrhea, epistaxis, anosmia, or others depending on the structures involved. The differential diagnosis of paranasal sinus masses on imaging studies is broad and can include inflammatory, congenital, or neoplastic masses; leading to the requirement of biopsy for definitive diagnosis. Tissue sample is usually obtained via an endoscopic approach. The prognosis of such a presentation is not well described in the literature, but it is usually guarded due to the advanced stage of the disease and generally a poorly differentiated primary tumor. Treatments usually aim to reduce the burden of disease and debulk the tumor mass for palliative purposes. We present a case of a 71-year-old male presenting with unilateral proptosis and periorbital swelling secondary to prostatic metastasis.

ABSTRACT

The prevalence of oropharyngeal squamous cell carcinoma has been increasing in North America due to human papillomavirus-associated disease. It is molecularly distinct and differs from other head and neck cancers due to the young population and high survival rate. The treatment regimens currently in place cause significant long-term toxicities. Studies have transitioned from mortality-based outcomes to patient-reported outcomes assessing quality of life. There are many completed and ongoing trials investigating alternative therapy regimens or de-escalation strategies to minimize the negative secondary effects while maintaining overall survival and disease-free survival. The goal of this review is to discuss the most recent advancements within the field while summarizing and reviewing the available evidence.

ABSTRACT

We hereby present a rare case of laryngeal zoster presenting with unilateral odynophagia and hemifacial pain in an immunocompetent host. Visualization of the characteristic vesicles is challenging given their short-lived and at times delayed appearance; thus, laryngeal zoster may be a largely unrecognized cause of laryngitis and cranial neuropathies. Heightened awareness may improve prompt diagnosis, referral and initiation of antiviral therapy, while guiding patient counselling on the associated long-term sequelae such as voice and swallowing impairments, and post-herpetic neuralgia.

ABSTRACT

OBJECTIVES/HYPOTHESIS: Quantity and quality of Otolaryngology-Head and Neck Surgery (OTL-HNS) research are increasing, yet patterns within Pediatric OTL-HNS publications are unknown. This study examines trends in the level of evidence of pediatric OTL-HNS articles over a 20-year period to quantify the growth and characterize contributing factors. STUDY DESIGN: Review article. METHODS: A retrospective review was conducted on 12 peer-reviewed OTL-HNS journals at three time-points: 1996, 2006, and 2016. Pediatric-specific OTL-HNS journals were selected; all were among the top 10 highest impact factor journals, with one pediatric-specific and one Canadian journal. Publication details, author characteristics, and study focus were collected. Papers were classified based on the Oxford Centre for Evidence-Based Medicine Levels of Evidence by two independent reviewers. RESULTS: Of the 1,733 articles reviewed, 727 met inclusion criteria. A greater absolute number of pediatric OTL-HNS articles were published over the years studied: from 95 in 1996 to 359 in 2016 (P < .001). As well, the absolute number of high-quality studies has increased over the study period, from 28 articles in 1996 to 100 articles in 2016. However, the relative percentage of high-quality papers remained stable between 27.9% and 32.2% with an average of 29.7% (P = .89). Higher impact factor journals did not tend to publish higher-quality pediatric OTL-HNS articles (P = .48). CONCLUSIONS: Over the past 20 years, there is no appreciable improvement in the proportion of high-quality publications in pediatric OTL-HNS; however, there is an overall greater number of high-quality papers within OTL-HNS literature. These findings likely relate to challenges of research within pediatric surgical specialties. LEVEL OF EVIDENCE: NA Laryngoscope, 132:1869-1876, 2022.

ABSTRACT

Metastatic renal cell carcinoma to the thyroid is a rare yet aggressive histopathologic diagnosis, which may often be omitted from the initial clinical differential. This is in part due to the long latency period between the initial renal primary and appearance of metastatic disease, coupled with the diagnostic limitations of fine-needle aspiration biopsies. We herein present an interesting case of a metastatic clear-cell renal-cell carcinoma mimicking an aggressive primary thyroid neoplasm, 10 years after a nephrectomy for a renal primary, highlighting key diagnostic and management considerations.

ABSTRACT

BACKGROUND: While some studies suggest that the BRAF V600E mutation correlates with a high-risk phenotype in papillary thyroid microcarcinoma (PTMC), more evidence is necessary before this mutation can be used to help guide decision making in the management of small thyroid nodules. This study investigated whether BRAF V600E mutation is associated with aggressive features in PTMC (≤ 1 cm) and small PTC (1-1.5 cm). METHODS: Retrospective chart review was performed on 121 patient cases. Patients who underwent thyroid surgery for PTMC (≤ 1 cm) or small PTC (1-1.5 cm) were included if molecular testing was done for BRAF V600E mutation. Two study groups were created based on tumour size: PTMC (n = 55) and small PTC (n = 66). The groups were analysed for the presence of a BRAF V600E mutation and aggressive features, including macroscopic extrathyroidal extension (ETE), lymph node metastasis (LNM), and high-risk histological features (tall cell, columnar cell, hobnail, solid/trabecular, and diffuse sclerosing). The Fischer exact test was used to calculate statistical significance. RESULTS: BRAF V600E mutations were detected in 43.6% of PTMC and 42.4% of small PTC. Of the mutated PTMC nodules, 54.1% demonstrated aggressive characteristics as compared to 19.4% of the non-mutated PTMCs (p = 0.010). Of the mutated small PTC tumours, 82.1% had aggressive features. In contrast, 28.9% of the non-mutated small PTCs showed aggressive features (p < 0.001). CONCLUSIONS: Our findings demonstrate an association between a BRAF V600E mutation and aggressive features in PTMC (≤ 1 cm) and small PTC (1-1.5 cm). Therefore, determining the molecular status of these thyroid nodules for the presence of BRAF V600E can help guide patient management.

ABSTRACT

OBJECTIVE: The purpose of this study was to evaluate the quality of evidence of rhinology and rhinologic skull base surgery (RSBS) research and its evolution over the past decade. STUDY DESIGN: Review article. SETTING: We reviewed articles from 2007 to 2019 in 4 leading peer-reviewed otolaryngology journals and 3 rhinology-specific journals. METHODS: The articles were reviewed and levels of evidence were assigned using the Oxford Centre for Evidence-Based Medicine 2011 guidelines. High quality was defined as level of evidence 1 or 2. RESULTS: In total, 1835 articles were reviewed in this study spanning a 13-year period. Overall, the absolute number of RSBS publications increased significantly 22.6% per year, from 108 articles in 2007 to 481 in 2019 (P < .001; 95% CI, 7.9-37.2). In 2007, only 13 articles, or 15%, were high quality, and this grew to 146 articles, or 39%, in 2019. A 14.0% per year exponential increase in the number of high-quality publications was found to be statistically significant (P < .001; 95% CI, 7.2, 20.7). Overall, high-quality publications represented just 25.8% of RSBS articles overall. There was no significant difference in quality between rhinology-specific journals and general otolaryngology journals (χ2 = 3.1, P = .077). CONCLUSION: The number of overall publications and of high-quality RSBS publications has significantly increased over the past decade. However, the proportion of high-quality studies continues to represent a minority of total RSBS research.

ABSTRACT

OBJECTIVE: Our purpose is to examine the effect of different classes of anxiolytics on cognitive flexibility. BACKGROUND: Situational stressors and anxiety impede performance on "creativity" tests requiring cognitive flexibility. Noradrenergic agents have been shown to modulate cognitive flexibility as assessed by performance on anagrams. To determine whether these findings on noradrenergic modulation of cognitive flexibility are specific to the noradrenergic system or are a nonspecific anxiety effect, we compared the effects of propranolol, lorazepam, and placebo on the anagram task. METHODS: Subjects attended 3 test sessions. Prior to each session, subjects were given 1 of the 3 drugs. As in previous research, the natural log of the solution latency of each test item was summed for each test session and compared across drug conditions. RESULTS: For subjects able to solve the anagrams, solution times after propranolol, but not lorazepam, were significantly lower than after placebo. CONCLUSIONS: Therefore, this suggests that the phenomenon of noradrenergic modulation of cognitive flexibility does not result from a nonspecific anxiolytic effect, but rather is specific to the noradrenergic system.
