Survival and prognosis of surgical head and neck cancer patients aged 80 years and older.

Introduction: Elderly patients (≥80 years of age) with head and neck cancer (HNC) can prove a management challenge due to concerns regarding their suitability for surgery. This study aims to describe the characteristics and outcomes of elderly patients undergoing HNC surgery. Methods: A retrospective review of elderly patients undergoing HNC surgery was conducted. Demographics, comorbidities, tumor characteristics, surgical procedure type, postoperative complications, and disposition were reviewed. Overall survival (OS) in the elderly cohort was compared against younger patients (<80 years). Results: A total of 595 patients were included, of whom 86 were aged >80 years (71% male; mean age 84.8, range 80.0-98.8 years). The overall complication rate was 43%. When compared with younger patients (n = 509), elderly patients had reduced OS (risk ratio: 2.0, 95% CI: 1.3-3.2), higher 90-day mortality (8.1% vs. 2.3%, p = .005), and lower 5-year survival (43.5% vs. 64.1%, p < .001). However, survival was comparable to age-specific life expectancy. There was no difference in OS, 90-day mortality, and 5-year survival when comparing >85 (n = 33) and 80-85 (n = 53) age groups. Conclusions: Chronological age alone should not negatively influence decision-making in HNC surgery the elderly. With careful preoperative selection and optimization, surgery can be performed at acceptable risk with good outcomes in elderly patients. Level of evidence: IV.

Integration of an enhanced recovery after surgery program for patients undergoing pituitary surgery.

Evidence-based enhanced recovery after surgery (ERAS) programs aim to improve patient outcomes and shorten hospital stays. The objective of this study is to describe the development, implementation, and evolution of an ERAS protocol to optimize the perioperative management for patients undergoing endoscopic skull base surgery for pituitary tumors. A systematic review of the literature was performed, best practices were discussed with stakeholders, and institutional guidelines were established and implemented. Key performance indicators (KPI) were measured and patient-reported outcome surveys were collected. The ERAS protocol was introduced successfully at our institution. We describe the process of initiation of the program and the perioperative management of our patients. We demonstrated the feasibility of integration of ERAS protocols for pituitary tumors with multidisciplinary engagement, with a particular emphasis on the use of data informatics and metrics to monitor outcomes. We expect that this approach will translate to improved quality of care for these often-complex patients.

Tracheostomy dependence following "organ preservation" (chemo)radiation protocol for laryngeal and hypopharyngeal cancers.

BACKGROUND: Patients receiving primary (chemo)radiotherapy for laryngeal or hypopharyngeal cancer risk developing severe laryngeal dysfunction and becoming tracheostomy dependent, detracting from the benefits of organ preservation. We aim to describe the airway outcomes for this cohort and identify risk factors for developing tracheostomy dependence. METHODS: Patients with laryngeal or hypopharyngeal cancer who were recommended for and underwent primary (chemo)radiotherapy over a 6-year period were identified from a tertiary hospital Head and Neck cancer database. Patient, tumor, and treatment details were collected and analyzed. RESULTS: Of 166 patients, 18.7% (N = 31) required tracheostomy insertion. Advanced tumor classification was the only significant predictor (p < 0.00001). Successful decannulation was observed in 12.9% (N = 4). Decannulation was observably less successful with advanced tumors, bilateral vocal cord immobility, tracheostomies inserted under emergency conditions. CONCLUSION: We quantified tracheostomy insertion rates and dependence in patients undergoing "organ-preserving" (chemo)radiotherapy, to assist in the pre-treatment counseling of patients opting for this approach.

Lessons learnt from the global iodinated contrast media shortage in head and neck imaging.

A recent shortage in the global supply of iodinated contrast media (ICM) has required health service providers to review their contrast administration policies and implement strategies to conserve inventory. This article will review the current best practices in head and neck imaging for a variety of common presentations and provide examples where alternative imaging can be considered due to the recent ICM shortage. Ultrasound and MRI techniques can feature heavily in many diagnostic processes in head and neck pathology, and a variety of common presentations can be appropriately investigated through clinical evaluation or naso-endoscopy. In many instances, for the routine assessment of non-acute adult and paediatric head and neck presentations, the use of contrast-enhanced CT can be safely minimised to conserve ICM if required.

The Influence of Hospital Volume on the Outcomes of Nasopharyngeal, Sinonasal, and Skull-Base Tumors: A Systematic Review of the Literature.

Objective The center of excellence model of health care hypothesizes that increased volume in a specialized center will lead to better and more affordable care. We sought to characterize the volume-outcome data for surgically treated sinonasal and skull base tumors and (chemo) radiation-treated nasopharyngeal malignancy. Design Systematic review of the literature. Setting This review included national database and multi-institutional studies published between 1990 and 2019. Participants PubMed was interrogated for keywords "hospital volume," "facility volume," and outcomes for "Nasopharyngeal carcinoma," "Sinonasal carcinomas," "Pituitary Tumors," "Acoustic Neuromas," "Chordomas," and "Skull Base Tumors" to identify studies. Single-institution studies and self-reported surveys were excluded. Main outcome measures The main outcome of interest in malignant pathologies was survival; and in benign pathologies it was treatment-related complications. Results A total of 20 studies met inclusion criteria. The average number of patients per study was 4,052, and ranged from 394 to 9,950 patients. Six of seven studies on malignant pathology demonstrated improved survival with treatment in high volume centers and one showed no association with survival. Ten of thirteen studies on benign disease showed reduced risk of complications, while one study demonstrated both an increased and decreased association of complications. Two studies showed no volume-outcome associations. Conclusion This systematic review demonstrates that a positive volume-outcome relationship exists for most pathologies of the skull base, with some exceptions. The relative dearth of literature supports further research to understand the effect of centralization of care on treatment outcomes.

Diagnosis and surgical repair of delayed tracheal perforation post thyroidectomy in context of previous cranio-spinal radiotherapy - A case report.

INTRODUCTION AND IMPORTANCE: This is the first case of delayed tracheal perforation post total thyroidectomy in the context of previous radiotherapy to the neck. Such a presentation can be easily misdiagnosed and managed as a seroma at significant risk to the patient, as the latter had no precipitating factors and cardiorespiratory compromise. There are nineteen previously described cases of delayed tracheal injury post thyroidectomy of variable severity and variable intervention. CASE PRESENTATION: A 51-year-old man presented with non-tender anterior neck surgical emphysema initially diagnosed on bedside ultrasound and plain X-ray, 22 days following total thyroidectomy and central neck dissection. His background was significant for childhood acute lymphoblastic leukaemia requiring chemotherapy and cranio-spinal radiotherapy. He underwent total thyroidectomy, for multiple bilateral thyroid nodules found on cranio-spinal MRI surveillance concerning for follicular neoplasm. There were significant amount of adhesions tethering the thyroid secondary to prior radiotherapy but no tracheal injury intra-operatively. CLINICAL DISCUSSION: At presentation, no source of air leak was identified on Computer Tomography. He failed conservative management. During surgical exploration, a 2 mm tracheal perforation at the right cricothyroid joint was closed with the right sternothyroid muscle due to the proximity of the perforation with the recurrent right laryngeal nerve. Tisseel was applied over the repair. He recovered without further complications. CONCLUSION: Sudden onset neck swelling post thyroidectomy in the context of significant scaring from radiotherapy, should raise the suspicion of surgical emphysema in the neck patients and confirmed with plain x-ray. Such patients should have multidisciplinary tertiary care.

Clinicopathological characteristics and clinical morbidity in high-risk head and neck cutaneous squamous cell carcinoma patients in Western Australia.

BACKGROUND: There is no registry data on morbidity and mortality of high-risk cutaneous squamous cell carcinoma (cSCC) in Australia. AIM: To examine the clinicopathological features, mortality and morbidity in high-risk cSCC patients in Western Australia (WA). METHODS: A retrospective cohort study was conducted through hospital record review on cSCC patients discussed at multidisciplinary meetings at the two largest WA hospitals between March 2015 and December 2016. RESULTS: Of 141 patients, 129 were evaluable, with median follow up of 43.9 (range 3.0-53.2) months. Patients were predominantly older males (84%) with significant comorbidities (Charlson Comorbidity Index (CCI) ≥5; 76%) and history of previous nonmelanoma skin cancer (57%) with advanced disease (57% stage IV without distant metastasis; American Joint Committee on Cancer, 7th edition). Pathological high-risk features were common including nodal extracapsular extension (47%) and cranial nerve involvement (16%). Clinical morbidity was significant with a median of 2 (range 0-13) excisions and 2 (range 0-21) cSCC-related hospitalisations for any cSCC event following the index case discussion. Recurrences of the primary index lesion occurred in 60% of patients and 20% had ≥2 recurrences. Median overall survival for patients with nonmetastatic disease was 39.8 (range 25.9-53.7) months and 16.1 (range 0.2-32.0) months for metastatic disease. CCI ≥5, advanced nodal stage and ≥2 recurrences were significantly associated with mortality on multivariable analyses (P < 0.05). Nodal extracapsular extension and any recurrences were identified as significant risk factors for disease-specific mortality on multivariable analyses (P < 0.05). CONCLUSION: High-risk cSCC patients have significant health needs represented by high-baseline comorbidities, multiplicity of cSCC events and the number of healthcare-associated interventions. There is an unmet need for robust cancer data collection.

Vincristine-Induced Bilateral Vocal Cord Palsy in an Adult Male With Diffuse Large B-Cell Lymphoma.

Acute bilateral vocal cord palsy (BLVCP) is an airway emergency. Elucidating the underlying cause is imperative to enable appropriate management. Vincristine-related neurotoxicity is a potentially reversible cause of BLVCP and is rarely described in the literature. We report a case of a 65-year-old man who presented with acutely worsening dyspnoea and stridor following his fifth cycle of rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone (R-CHOP) chemotherapy for hematological malignancy. His airway limitation was managed with supportive measures until he was able to compensate, at which point he was discharged home. His chemotherapy regimen was altered and he underwent serial examinations until he regained full vocal cord mobility at three months following his initial presentation. Through reporting this case, we hope to raise awareness of the potential for vincristine to cause sudden BLVCP and resultant airway deterioration, as well as emphasize the reversible nature of the condition with prompt cessation of therapy.

Diagnostic and Prognostic Utility of 18F-FDG PET/CT in Recurrent Salivary Gland Cancers.

OBJECTIVE. The role of 18F-FDG PET/CT in the evaluation of recurrent salivary gland tumors remains poorly defined. We investigated the diagnostic and prognostic utility of PET in this setting. MATERIALS AND METHODS. A total of 146 patients with recurrent salivary gland cancer were treated at our institution between January 2002 and December 2015. Patients who underwent FDG PET/CT and conventional imaging (CT or MRI) within 3 months of recurrence (n = 78) were included in this retrospective analysis. On FDG PET/CT, we measured the SUVmax, total body metabolic tumor volume of all lesions, and total lesion glycolysis of all lesions to determine the intensity and extent of FDG-avid disease. We assessed the correlation of FDG PET/CT findings with clinicopathologic features, progression-free survival, and overall survival. RESULTS. FDG PET/CT was positive for recurrence in 74 of 78 patients (94.9%) and falsely negative in four patients (5.1%). In comparison with conventional imaging, FDG PET/CT performed for restaging detected additional recurrent lesions in 14 patients (17.9%). The median SUVmax was 7.4, the median total body metabolic tumor volume was 30.1 cm3, and median total lesion glycolysis was 97.3 g/mL × cm3. Sixty-six patients had progressive disease, and 54 died. Univariate and multivariate Cox hazards analysis identified pathologic risk group (p = .04), total body metabolic tumor volume (p < .001), and total lesion glycolysis (p < .001) as independent prognostic factors for progression-free survival and identified age (p = .05), total body metabolic tumor volume (p < .001), and total lesion glycolysis (p < .001) as independent prognostic factors for overall survival. CONCLUSION. In patients with recurrent salivary gland cancer, FDG PET/CT is useful as a single test for defining the extent of disease and providing prognostic information, which may help in selecting appropriate treatment strategies.

Metastatic Cutaneous Squamous Cell Carcinoma Involving the Parotid Gland: Experience Outside of the Sun Belt.

OBJECTIVE: To characterize a subset of patients with metastatic head and neck cutaneous squamous cell carcinoma in a tertiary North American center and describe oncologic outcomes following definitive treatment. STUDY DESIGN: Retrospective chart review. SETTING: National Cancer Institute-designated Comprehensive Cancer Center. METHODS: We conducted a retrospective chart review of patients with cutaneous squamous cell carcinoma with metastases to intraparotid lymph nodes who underwent parotidectomy between 1993 and 2020. Baseline patient and tumor characteristics were assessed. Regional control, disease-specific survival, and overall survival were estimated using Kaplan-Meier method. Multivariate analysis was used to determine the relationship between adverse pathological features and survival. RESULTS: A total of 122 patients were included. The median age was 76, 84.4% of patients were male, and 17.2% were immunosuppressed. Regional control, disease-specific survival, and overall survival were 68.5%, 70.7%, and 59.4% at 5 years, respectively. Perineural and lymphovascular invasion were predictive of worse disease-specific survival. Extracapsular spread was observed in 90.2% of patients and was not a significant predictor of outcome. CONCLUSIONS: We found the demographics and oncologic outcomes of our cohort in the Northeast United States to be comparable with those previously reported in Australia and the Sun Belt of the United States. We noted a high rate of extracapsular spread but did not find it to be a significant predictor of recurrence or survival. Future efforts should address the impact of extracapsular spread on prognosis and adjuvant treatment decisions.

Oncologic and functional outcomes following laryngectomy for locally advanced thyroid cancer.

BACKGROUND AND OBJECTIVES: Total laryngectomy in thyroid cancer is controversial. Functional and oncologic outcomes are needed to inform surgical indications in this population. METHODS: A retrospective cohort study was performed at a tertiary referral center from 1997 to 2018 to identify patients with a diagnosis of thyroid carcinoma who underwent total laryngectomy. Complications, survival outcomes, and functional outcomes were analyzed. RESULTS: Thirty patients met the inclusion criteria. The mean age was 62 years (range, 30-88 years) and the male-to-female ratio was 1:2.75. The most common diagnosis was well-differentiated thyroid cancer (53.3%), followed by poorly differentiated (30%) and anaplastic (16.7%). Total laryngectomy was performed with a 10% rate of Clavien-Dindo Grade III-V complications. The median overall survival was 40 months (range, 1-237). Five-year overall survival was 39.5% and disease-specific survival was 51.1%. Locoregional control was achieved in 80.0% of patients. Twelve months postoperatively, 100% of surviving patients were taking oral intake and 86.4% had a self-reported functional voice. CONCLUSION: Total laryngectomy for locally advanced thyroid cancer is safe and provides acceptable rates of locoregional control. While the risk of distant metastases remains high, advances in systemic therapy may justify aggressive local control strategies to improve the quality of life.

A Cure for PAINS? A Novel Approach to Management of Proton-Associated Internal Nasal Valve Stenosis.

Acquired internal nasal stenosis as a result of radiotherapy to the sinonasal region can be highly distressing for patients and difficult to correct surgically. We describe our experience using a controlled radial expansion balloon to dilate the area of stenosis, followed by stenting to the region. We achieved excellent results in 3 patients using this technique, with improvement in subjective nasal airflow across 100% of stenoses and complete resolution in 83%. This technique offers a simple and low-morbidity option for the management of acquired anterior nasal stenosis and is of particular value in cases of irradiation, which has the potential for poor tissue healing.

Primary tumor volume as a predictor of distant metastases and survival in patients with sinonasal mucosal melanoma.

BACKGROUND: Sinonasal mucosal melanoma (SNMM) is an aggressive cancer with high mortality. Identifying patients at risk of distant metastasis assists with management and prognostication. We aimed to define the relationship between volume, survival, and risk of distant metastases. METHODS: A retrospective review of all patients with SNMM treated at a single institution over a 21-year period was conducted. Tumor volume was calculated using cross-sectional imaging and survival analysis was performed. RESULTS: Sixty-one patients were included. Tumor volume was predictive of local progression-free survival (P = .03), distant metastases-free survival (DMFS) (P = .002), and overall survival (OS) (P = .02). It was a better predictor than AJCC stage and T-classification. Tumor volume equal to or greater than 5 cm3 was associated with a significantly worse DMFS and OS (P = .02 and .009, respectively). CONCLUSION: Calculation of tumor volume assists in quantifying the risk of distant metastases and death in SNMM.

Pre-treatment wait time for head and neck cancer patients in Western Australia: description of a new metric and examination of predictive factors.

BACKGROUND: Prolonged pre-treatment wait times in head and neck cancer are associated with increased morbidity and reduced survival. Traditional metrics exclude delays prior to biopsy, which represents an important and measurable period of time. This study aims to describe total wait time for head and neck cancer patients in our institution, to define a more accurate representation of the clinically relevant pre-treatment wait time, and to evaluate predictive factors for prolonged wait times. METHODS: A retrospective review of head and neck cancer patients treated over 2 years in a tertiary referral centre was conducted. Patient demographics, referral symptoms, tumour details, treatment plan and key dates were analysed to identify total wait time and factors predictive of increased wait time. RESULTS: Two hundred and ninety-four patients were included. Mean total wait time from initial referral to treatment initiation was 71.6 (median 61) days. The period from referral to biopsy represented 29% of mean total wait time. Factors predictive of increased wait time included presenting symptom of hoarseness, laryngeal cancer and treatment with definitive radiotherapy. CONCLUSIONS: This study demonstrates that time from referral to biopsy represents a significant portion of total wait time, and we suggest that this be incorporated into future wait time metrics for improved clinical relevance. Furthermore, we have identified factors predicting increased wait time which can be targeted for future service improvement.

Tonsillectomy complicated by jugular vein thrombosis and pulmonary embolism.

To report an unusual and life-threatening complication of routine tonsillectomy, and review the relevant medical literature. A Medline database search was performed to identify reports of thromboembolic complications of tonsillectomy. Thromboembolic complications following tonsillectomy are rare, and no previously reported cases of post-operative jugular vein thrombosis and pulmonary embolism are described. We report a case of an 18-year old previously healthy woman who presented with a sub-massive pulmonary embolus following tonsillectomy. It is believed that the embolus originated from a post-operative jugular vein thrombosis. This is the first report of jugular vein thrombosis and pulmonary embolism following tonsillectomy. Knowledge of this potentially life-threatening complication is vital for otolaryngologists routinely performing this procedure.

Positron emission tomography-positive thyroid nodules: rate of malignancy and histological features.

BACKGROUND: Thyroid nodules may be incidentally detected on (18) F-FDG-positron emission tomography (PET) scans. Previous reports suggest a high incidence of malignancy in FDG-avid nodules. The aims of this study were to examine the incidence of malignancy in a large cohort and to report on the histological features. The findings suggest that poor prognostic histologic features are often associated with FDG-avid thyroid nodules and this may have clinical implications. METHODS: A retrospective review of prospectively collected data was conducted. A database containing all patients who underwent PET scanning at a single tertiary referral centre from January 2006 to January 2013 was searched to identify those with incidental PET-positive thyroid nodules. Patients with known preexisting thyroid disease were excluded from analysis. The demographics, fine-needle aspiration (FNA) biopsy result and operative histopathology were analysed. RESULTS: A total of 27 851 FDG-PET scans were performed of which 221 found incidental PET-positive thyroid nodules (incidence 0.8%). Fifty-three patients went on to have further investigation and 21 of these were found to have malignant disease (incidence 39.6%). Histopathological examination of 12 malignant nodules revealed an expected rate of poor prognostic features, including poorly differentiated subtype (8.3%), lymphovascular invasion (16.7%), perineural invasion (8.3%) and extrathyroid extension (33.3%). CONCLUSION: Our data indicate that PET-positive thyroid nodules are associated with a high incidence of malignancy. This finding provides strong support for further investigation including FNA biopsy in all surgically suitable patients.

Retrograde ureteric stent insertion in the management of infected obstructed kidneys.

OBJECTIVES: To quantify the outcomes of retrograde ureteric stenting in the setting of infected hydronephrosis secondary to ureteric calculi. PATIENTS AND METHODS: Prospective analysis of all patients over a 15-month period admitted with infected obstructed kidneys secondary to ureteric calculi. Inclusion criteria were based on clinical evidence of systemic inflammatory response syndrome (SIRS) and radiological evidence of obstructing ureteric calculi. Outcome measures included success of procedure, admission to intensive care unit (ICU), length of hospital stay, morbidity, and all-cause mortality during hospital admission. RESULTS: In all, 52 patients were included. Success of retrograde ureteric stenting was 98%. In all, 17% of patients required an ICU admission, with a post ureteric instrumentation ICU admissions rate of 6%. The mean white cell count and serum creatinine improved significantly after the procedure. Major complication rate included septic shock 6%, but there were no episodes of major haemorrhage and no deaths. CONCLUSION: Retrograde ureteric stenting is safe and effective in infected obstructed kidneys with results comparable to percutaneous nephrostomy tube insertion. Post instrumentation ICU admissions occur in 6% of retrograde stentings.
