Survival outcomes in head and neck squamous cell carcinoma of unknown primary: A national cohort study.

INTRODUCTION: To investigate factors influencing survival in head and neck squamous cell carcinoma of unknown primary (HNSCCUP). METHODS: A retrospective observational cohort study was conducted, over 5 years from January 2015, in UK Head and Neck centres, of consecutive adults undergoing 18F-Fluorodeoxyglucose-PET-CT within 3 months of diagnosis with metastatic cervical squamous cell carcinoma. Patients treated as HNSCCUP underwent survival analysis, stratified by neck dissection and/or radiotherapy to the ipsilateral neck, and by HPV status. RESULTS: Data were received from 57 centres for 965 patients, of whom 482 started treatment for HNSCCUP (65.7% HPV-positive, n = 282/429). Five-year overall survival (OS) for HPV-positive patients was 85.0% (95% CI 78.4-92.3) and 43.5% (95% CI 32.9-57.5) for HPV-negative. HPV-negative status was associated with worse OS, disease-free (DFS), and disease-specific (DSS) survival (all p < .0001 on log-rank test) but not local control (LC) (p = .16). Unilateral HPV-positive disease treated with surgery alone was associated with significantly worse DFS (p < .0001) and LC (p < .0001) compared to radiotherapy alone or combined modalities (5-year DFS: 24.9%, 82.3% and 94.3%; 5-year LC: 41.8%, 98.8% and 98.6%). OS was not significantly different (p = .16). Unilateral HPV-negative disease treated with surgery alone was associated with significantly worse LC (p = .017) (5-year LC: estimate unavailable, 93.3% and 96.6%, respectively). Small numbers with bilateral disease precluded meaningful sub-group analysis. CONCLUSIONS: HPV status is associated with variable management and outcomes in HNSCCUP. Unilateral neck disease is treated variably and associated with poorer outcomes when managed with surgery alone. The impact of diagnostic oropharyngeal surgery on primary site emergence, survival and functional outcomes is unestablished.

Qualitative study exploring the design of a patient-reported symptom-based risk stratification system for suspected head and neck cancer referrals: protocol for work packages 1 and 2 within the EVEREST-HN programme.

INTRODUCTION: Between 2009/2010 and 2019/2020, England witnessed an increase in suspected head and neck cancer (sHNC) referrals from 140 to 404 patients per 100 000 population. 1 in 10 patients are not seen within the 2-week target, contributing to patient anxiety. We will develop a pathway for sHNC referrals, based on the Head and Neck Cancer Risk Calculator. The evolution of a patient-reported symptom-based risk stratification system to redesign the sHNC referral pathway (EVEREST-HN) Programme comprises six work packages (WPs). This protocol describes WP1 and WP2. WP1 will obtain an understanding of language to optimise the SYmptom iNput Clinical (SYNC) system patient-reported symptom questionnaire for sHNC referrals and outline requirements for the SYNC system. WP2 will codesign key elements of the SYNC system, including the SYNC Questionnaire, and accompanying behaviour change materials. METHODS AND ANALYSIS: WP1 will be conducted at three acute National Health Service (NHS) trusts with variation in service delivery models and ensuring a broad mixture of social, economic and cultural backgrounds of participants. Up to 150 patients with sHNC (n=50 per site) and 15 clinicians (n=5 per site) will be recruited. WP1 will use qualitative methods including interviews, observation and recordings of consultations. Rapid qualitative analysis and inductive thematic analysis will be used to analyse the data. WP2 will recruit lay patient representatives to participate in online focus groups (n=8 per focus group), think-aloud technique and experience-based codesign and will be analysed using qualitative and quantitative approaches. ETHICS AND DISSEMINATION: The committee for clinical research at The Royal Marsden, a research ethics committee and the Health Research Authority approved this protocol. All participants will give informed consent. Ethical issues of working with patients on an urgent cancer diagnostic pathway have been considered. Findings will be disseminated via journal publications, conference presentations and public engagement activities.

Socioeconomic and ethnic disparities associated with access to cochlear implantation for severe-to-profound hearing loss: A multicentre observational study of UK adults.

BACKGROUND: Patients with severe-to-profound hearing loss may benefit from management with cochlear implants. These patients need a referral to a cochlear implant team for further assessment and possible surgery. The referral pathway may result in varied access to hearing healthcare. This study aimed to explore referral patterns and whether there were any socioeconomic or ethnic associations with the likelihood of referral. The primary outcome was to determine factors influencing referral for implant assessment. The secondary outcome was to identify factors impacting whether healthcare professionals had discussed the option of referral. METHODS AND FINDINGS: A multicentre multidisciplinary observational study was conducted in secondary care Otolaryngology and Audiology units in Great Britain. Adults fulfilling NICE (2019) audiometric criteria for implant assessment were identified over a 6-month period between 1 July and 31 December 2021. Patient- and site-specific characteristics were extracted. Multivariable binary logistic regression was employed to compare a range of factors influencing the likelihood of implant discussion and referral including patient-specific (demographics, past medical history, and degree of hearing loss) and site-specific factors (cochlear implant champion and whether the hospital performed implants). Hospitals across all 4 devolved nations of the UK were invited to participate, with data submitted from 36 urban hospitals across England, Scotland, and Wales. Nine hospitals (25%) conducted cochlear implant assessments. The majority of patients lived in England (n = 5,587, 86.2%); the rest lived in Wales (n = 419, 6.5%) and Scotland (n = 233, 3.6%). The mean patient age was 72 ± 19 years (mean ± standard deviation); 54% were male, and 75·3% of participants were white, 6·3% were Asian, 1·5% were black, 0·05% were mixed, and 4·6% were self-defined as a different ethnicity. Of 6,482 submitted patients meeting pure tone audiometric thresholds for cochlear implantation, 311 already had a cochlear implant. Of the remaining 6,171, 35.7% were informed they were eligible for an implant, but only 9.7% were referred for assessment. When adjusted for site- and patient-specific factors, stand-out findings included that adults were less likely to be referred if they lived in more deprived area decile within Indices of Multiple Deprivation (4th (odds ratio (OR): 2·19; 95% confidence interval (CI): [1·31, 3·66]; p = 0·002), 5th (2·02; [1·21, 3·38]; p = 0·05), 6th (2·32; [1·41, 3·83]; p = 0.05), and 8th (2·07; [1·25, 3·42]; p = 0·004)), lived in London (0·40; [0·29, 0·57]; p < 0·001), were male (females 1·52; [1·27, 1·81]; p < 0·001), or were older (0·97; [0·96, 0·97]; p < 0·001). They were less likely to be informed of their potential eligibility if they lived in more deprived areas (4th (1·99; [1·49, 2·66]; p < 0·001), 5th (1·75; [1·31, 2·33], p < 0·001), 6th (1·85; [1·39, 2·45]; p < 0·001), 7th (1·66; [1·25, 2·21]; p < 0·001), and 8th (1·74; [1·31, 2·31]; p < 0·001) deciles), the North of England or London (North 0·74; [0·62, 0·89]; p = 0·001; London 0·44; [0·35, 0·56]; p < 0·001), were of Asian or black ethnic backgrounds compared to white patients (Asian 0·58; [0·43, 0·79]; p < 0·001; black 0·56; [0·34, 0·92]; p = 0·021), were male (females 1·46; [1·31, 1·62]; p < 0·001), or were older (0·98; [0·98, 0·98]; p < 0·001). The study methodology was limited by its observational nature, reliance on accurate documentation of the referring service, and potential underrepresentation of certain demographic groups. CONCLUSIONS: The majority of adults meeting pure tone audiometric threshold criteria for cochlear implantation are currently not appropriately referred for assessment. There is scope to target underrepresented patient groups to improve referral rates. Future research should engage stakeholders to explore the reasons behind the disparities. Implementing straightforward measures, such as educational initiatives and automated pop-up tools for immediate identification, can help streamline the referral process.

Step Serial Sectioning in Head and Neck Squamous Cell Carcinoma of Unknown Primary.

Importance: Patients with suspected head and neck squamous cell carcinoma of unknown primary (HNSCCUP) may undergo tonsillectomy and tongue base mucosectomy (TBM) to help identify clinicoradiologically occult primary disease. It is hypothesized that when these diagnostic specimens are analyzed, conventional histopathological (CH) techniques risk missing small primary tumors that may be hidden in the tissue blocks. Objective: To establish the outcomes of a step serial sectioning (SSS) histopathological technique vs CH when analyzing diagnostic tissue specimens from TBM and tonsillectomy performed for HNSCCUP. Design, Setting, and Participants: The MOSES prospective multicenter noninterventional cohort study was conducted over a 25-month period from November 2019 at secondary and tertiary care ear, nose, and throat departments in the United Kingdom and included adults with clinicoradiologically occult HNSCCUP who were undergoing TBM. Intervention: Conventional histopathological techniques performed on TBM and tonsillectomy specimens at participating centers, followed by SSS performed at the central laboratory. Main Outcome: Identification of cancer on central histopathological review of TBM and tonsillectomy specimens. Results: Tissue from 58 eligible patients was analyzed (median [range] age, 58 [47-82] years; 10 women [17%]), with 20 480 sections cut in the laboratory and 4096 sections directly examined by a pathologist (median [range], 64 [28-135] per patient). The overall identification rate for TBM following SSS according to study protocol was 50.0% (95% CI, 37.5%-62.5%) and by subgroups was 42.9% (95% CI, 21.4%-67.4%) when performed following a negative bilateral tonsillectomy, 46.7% (95% CI, 24.8%-69.9%) at the same time as bilateral tonsillectomy, and 57.1% (95% CI, 36.5%-75.5%) following historic tonsillectomy. Conventional histopathological techniques at central review identified 2 undiagnosed primary tumors and revised the diagnosis of 2 other cases (1 nonmalignant and another down staged). Step serial sectioning identified a single additional tumor: an ipsilateral synchronous tongue base tumor for which a contralateral tumor had been identified on CH. Multifocal disease was seen in 5 (8.6%); all were human papillomavirus-related and in the tongue base. Conclusions and Relevance: In this multicenter cohort study of patients undergoing TBM for HNSCCUP, SSS was associated with added considerable histopathological workload with minimal additional diagnostic benefit. A second opinion for conventional histological techniques may be more beneficial. Synchronous primary disease should be considered when planning diagnostic oropharyngeal surgery for these patients.

Long-Term Follow-up (14 to 25 Years) Following Closed Reduction and Early Movement for Simple Dislocation of the Elbow.

BACKGROUND: We have previously reported on the midterm outcomes after a nonoperative protocol to treat simple dislocations of the elbow that included a short period of splinting followed by early movement. We have now performed extended follow-up of the original patient group from the prior study to determine whether the excellent results that previously had been reported were maintained in the long term and also to determine the rate of and need for any late surgical intervention. METHODS: We attempted to contact all of the patients from the original study group. We requested that they complete the Oxford Elbow Score (OES) survey, the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, and a validated patient satisfaction questionnaire. Patients also were requested to attend a face-to-face assessment to have a clinical examination that included neurovascular, range-of-motion, and ligamentous stability assessments. RESULTS: Seventy-one patients from the original patient group agreed to participate in the new study. The mean duration of follow-up was 19.3 years. At the time of the final follow-up, patients reported excellent functional outcome scores and a preserved functional range of movement in the injured elbow. The mean OES was 91.6 points, the mean DASH score was 5.22 points, and the mean satisfaction score was 90.9 points. None of the patients had undergone delayed or secondary surgery for instability during the interval period. CONCLUSIONS: This study demonstrated that the original excellent outcomes following treatment with a protocol of a short period of splinting and early movement remained excellent and were maintained into the very long term. LEVEL OF EVIDENCE: Therapeutic Level IV . See Instructions for Authors for a complete description of levels of evidence.

Complications following salvage transoral robotic surgery with and without reconstruction: A systematic review of the literature.

BACKGROUND: Transoral robotic surgery (TORS) has been used in the salvage setting for head and neck cancers both with and without reconstruction. The complications of salvage TORS and the effect of reconstruction on complications has not been studied. OBJECTIVE: To study the complications of salvage TORS and examine the effect of reconstruction on complication rates. METHOD: An electronic search of the English- language literature using PubMed, Medline, and the Cochrane database was conducted and a systematic review performed in accordance with PRISMA guidelines (CRD42020181057). RESULTS: A total of 23 studies including 533 patients have been published on salvage TORS.The average patient age was 61.2 years.Prior treatment was described for 420 patients.205 (48.8%) underwent prior definitive radiotherapy (RT).160 (38.1%) underwent definitive chemoradiotherapy (CRT).Only 55 (13.1%) had prior surgery.Overall, there were 158 complications with a pooled rate of 33.6% (95%CI: 25.4-42.3%).77 were major complications requiring surgical intervention with a pooled rate of 18.9% (95% CI: 14.8-23.3%).The number of patients undergoing reconstruction among salvage cases in the literature is 59 (9.19%), with 24 local flaps and 25 microvascular free flaps.Reconstruction was associated with lower overall hemorrhage rates but had no impact on major hemorrhage rates. CONCLUSIONS: The pooled incidence rates of major complications, major POH and emergency tracheostomy following salvage TORS are 18.9%, 10.5%, and 4.4%.The rate of death following salvage TORS is 3.6%. Reconstruction was associated with lower overall hemorrhage rate after salvage TORS but had no impact on major postoperative hemorrhage rates.

Functional and quality-of-life outcomes following salvage surgery for recurrent squamous cell carcinoma of the head and neck: a systematic review and meta-analysis.

BACKGROUND: Recurrent head and neck squamous cell carcinomas (HNSCC) are frequently managed with salvage surgery, but the impact these operations have on function and quality-of-life (QoL) is understudied. This review aimed to provide a quantitative and qualitative assessment of the functional and QoL effects of salvage surgical procedures. METHODS: Systematic review and meta-analysis were conducted of studies reporting QoL and function following salvage HNSCC resections. RESULTS: The search identified 415 articles and 34 were selected for inclusion. Pooled random effects analysis revealed long-term feeding and tracheostomy tube rates of 18% and 7%. Pooled long-term feeding tube rates in open oral and oropharyngeal, transoral robotic, total and partial laryngectomy surgeries were 41%, 25%, 11% and 4%. Eight studies used validated QoL questionnaires. CONCLUSIONS: Functional and QoL outcomes from salvage surgery are acceptable, but appear to be worse following open procedures. Prospective studies measuring changes over time are needed to assess these procedures impact on patient well-being.

Diagnostic accuracy of intraoperative margin assessment techniques in surgery for head and neck squamous cell carcinoma: A meta-analysis.

BACKGROUND: Positive margins following head and neck squamous cell carcinoma (HNSCC) surgery lead to significant morbidity and mortality. Existing Intraoperative Margin Assessment (IMA) techniques are not widely used due to limitations in sampling technique, time constraints and resource requirements. We performed a meta-analysis of the diagnostic performance of existing IMA techniques in HNSCC, providing a benchmark against which emerging techniques may be judged. METHODS: The study was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guidelines. Studies were included if they reported diagnostic metrics of techniques used during HNSCC surgery, compared with permanent histopathology. Screening, manuscript review and data extraction was performed by multiple independent observers. Pooled sensitivity and specificity were estimated using the bivariate random effects model. RESULTS: From an initial 2344 references, 35 studies were included for meta-analysis. Sensitivity (Sens), specificity (Spec), diagnostic odds ratio (DOR) and area under the receiver operating characteristic curve (AUROC) were calculated for each group (n, Sens, Spec, DOR, AUROC): frozen section = 13, 0.798, 0.991, 309.8, 0.976; tumour-targeted fluorescence (TTF) = 5, 0.957, 0.827, 66.4, 0.944; optical techniques = 10, 0.919, 0.855, 58.9, 0.925; touch imprint cytology = 3, 0.925, 0.988, 51.1, 0.919; topical staining = 4, 0.918, 0.759, 16.4, 0.833. CONCLUSIONS: Frozen section and TTF had the best diagnostic performance. Frozen section is limited by sampling error. TTF shows promise but involves administration of a systemic agent. Neither is currently in widespread clinical use. Emerging techniques must demonstrate competitive diagnostic accuracy whilst allowing rapid, reliable, cost-effective results.

Acute Carpal Tunnel Syndrome: Early Nerve Decompression and Surgical Stabilization for Bony Wrist Trauma.

We undertook this study to investigate the outcomes of surgical treatment for acute carpal tunnel syndrome following our protocol for concurrent nerve decompression and skeletal stabilization for bony wrist trauma to be undertaken within 48 hours. Methods: We identified all patients treated at our trauma center following this protocol between January 1, 2014 and December 31, 2019. All patients were clinically reviewed at least 12 months after surgery and assessed using the Brief Michigan Hand Outcomes Questionnaire, the Boston Carpal Tunnel Questionnaire, and sensory assessment with Semmes-Weinstein monofilament testing. Results: The study group was made up of 35 patients. Thirty-three patients were treated within 36 hours. Patients treated with our unit protocol for early surgery comprising nerve decompression and bony stabilization within 36 hours report excellent outcomes at medium term follow-up. Conclusions: We propose that nerve decompression and bony surgical stabilization should be undertaken as soon as practically possible once the diagnosis is made. This is emergent treatment to protect and preserve nerve function. In our experience, the vast majority of patients were treated within 24 hours; however, where a short period of observation was required, excellent results were generally achieved when treatment was completed within 36 hours.

Transoral robotic surgery in a modified Trendelenburg position for oropharyngeal squamous cell carcinoma in a patient with severe thoracic kyphosis.

BACKGROUND: Excessive flexion of the neck and upper back from severe kyphosis of the thoracic spine may limit treatment options for head and neck cancer (HNC). METHODS: We describe an innovative approach to transoral robotic surgery (TORS) in a patient with severe thoracic kyphosis and oropharyngeal squamous cell carcinoma (OPSCC) who was unsuitable for definitive radiotherapy. RESULTS: Detailed discussion of management pathway, perioperative considerations, and surgical challenges is presented. TORS lateral oropharyngectomy was successfully performed with the robotic system docked from the caudal end in a modified Trendelenburg position. CONCLUSIONS: With appropriate surgical and anesthetic planning, TORS for patients with severe thoracic kyphosis is a feasible and suitable treatment.

Systematic review and meta-analysis of occult contralateral nodal metastases in patients with oropharyngeal squamous carcinoma undergoing elective neck dissection.

A systematic review and meta-analysis was conducted to evaluate the occult contralateral nodal metastases (OCM) in patients undergoing bilateral neck dissection for surgically treated oropharyngeal squamous cell carcinoma (OPSCC). Following PRISMA guidelines, MEDLINE, Embase and Cochrane Controlled Register of Trials databases were searched for observational and experimental studies until March 2021. Search yielded 175 articles, of which 13 were included. Overall, OCM were seen in 9.8% of patients (95% CI: [5.7, 16.4], 839 patients, 12 studies, I2 65%). For ipsilateral cN0 necks, the OCM rate was 1.7% (95% CI: [0.1, 22.4], 150 patients, 8 studies, I2 0%) and for cN + necks the OCM rate was 9.8% (95% CI: [4.4, 20.3], 429 patients, 8 studies, I2 72%). Occult contralateral nodal metastases are uncommon in OPSCC patients with clinico-radiologically negative ipsilateral necks. Occult rates are higher in the contralateral neck when the ipsilateral neck is clinico-radiologically node positive.

Patterns of injury and treatment for distal radius fractures at a major trauma centre.

AIMS: Fractures of the distal radius are common, and form a considerable proportion of the trauma workload. We conducted a study to examine the patterns of injury and treatment for adult patients presenting with distal radius fractures to a major trauma centre serving an urban population. METHODS: We undertook a retrospective cohort study to identify all patients treated at our major trauma centre for a distal radius fracture between 1 June 2018 and 1 May 2021. We reviewed the medical records and imaging for each patient to examine patterns of injury and treatment. We undertook a binomial logistic regression to produce a predictive model for operative fixation or inpatient admission. RESULTS: Overall, 571 fractures of the distal radius were treated at our centre during the study period. A total of 146 (26%) patients required an inpatient admission, and 385 surgical procedures for fractures of the distal radius were recorded between June 2018 and May 2021. The most common mechanism of injury was a fall from a height of one metre or less. Of the total fractures, 59% (n = 337) were treated nonoperatively, and of those patients treated with surgery, locked anterior-plate fixation was the preferred technique (79%; n = 180). CONCLUSION: The epidemiology of distal radius fractures treated at our major trauma centre replicated the classical bimodal distribution described in the literature. Patient age, open fractures, and fracture classification were factors correlated with the decision to treat the fracture operatively. While most fractures were treated nonoperatively, locked anterior-plate fixation remains the predominant method of fixation for fractures of the distal radius; this is despite questions and continued debate about the best method of surgical fixation for these injuries.Cite this article: Bone Jt Open 2022;3(8):623-627.

Transoral Robotic Surgery for Recurrent Tumors of the Upper Aerodigestive Tract (RECUT): An International Cohort Study.

BACKGROUND: Transoral robotic surgery (TORS) is an emerging minimally invasive surgical treatment for residual, recurrent, and new primary head and neck cancers in previously irradiated fields, with limited evidence for its oncological effectiveness. METHODS: A retrospective observational cohort study of consecutive cases performed in 16 high-volume international centers before August 2018 was conducted (registered at clinicaltrials.gov [NCT04673929] as the RECUT study). Overall survival (OS), disease-free survival, disease-specific survivals (DSS), and local control (LC) were calculated using Kaplan-Meier estimates, with subgroups compared using log-rank tests and Cox proportional hazards modeling for multivariable analysis. Maximally selected rank statistics determined the cut point for closest surgical resection margin based on LC. RESULTS: Data for 278 eligible patients were analyzed, with median follow-up of 38.5 months. Two-year and 5-year outcomes were 69.0% and 62.2% for LC, 71.8% and 49.8% for OS, 47.2% and 35.7% for disease-free survival, and 78.7% and 59.1% for disease-specific survivals. The most discriminating margin cut point was 1.0 mm; the 2-year LC was 80.9% above and 54.2% below or equal to 1.0 mm. Increasing age, current smoking, primary tumor classification, and narrow surgical margins (≤1.0 mm) were statistically significantly associated with lower OS. Hemorrhage with return to theater was seen in 8.1% (n = 22 of 272), and 30-day mortality was 1.8% (n = 5 of 272). At 1 year, 10.8% (n = 21 of 195) used tracheostomies, 33.8% (n = 66 of 195) used gastrostomies, and 66.3% (n = 53 of 80) had maintained or improved normalcy of diet scores. CONCLUSIONS: Data from international centers show TORS to treat head and neck cancers in previously irradiated fields yields favorable outcomes for LC and survival. Where feasible, TORS should be considered the preferred surgical treatment in the salvage setting.

Methodology for the development of National Multidisciplinary Management Recommendations using a multi-stage meta-consensus initiative.

BACKGROUND: Methods for developing national recommendations vary widely. The successful adoption of new guidance into routine practice is dependent on buy-in from the clinicians delivering day-to-day patient care and must be considerate of existing resource constraints, as well as being aspirational in its scope. This initiative aimed to produce guidelines for the management of head and neck squamous cell carcinoma of unknown primary (HNSCCUP) using a novel methodology to maximise the likelihood of national adoption. METHODS: A voluntary steering committee oversaw 3 phases of development: 1) clarification of topic areas, data collection and assimilation, including systematic reviews and a National Audit of Practice; 2) a National Consensus Day, presenting data from the above to generate candidate consensus statements for indicative voting by attendees; and 3) a National Delphi Exercise seeking agreement on the candidate consensus statements, including representatives from all 58 UK Head and Neck Multidisciplinary Teams (MDT). Methodology was published online in advance of the Consensus Day and Delphi exercise. RESULTS: Four topic areas were identified to frame guideline development. The National Consensus Day was attended by 227 participants (54 in-person and 173 virtual). Results from 7 new systematic reviews were presented, alongside 7 expert stakeholder presentations and interim data from the National Audit and from relevant ongoing Clinical Trials. This resulted in the generation of 35 statements for indicative voting by attendees which, following steering committee ratification, led to 30 statements entering the National Delphi exercise. After 3 rounds (with a further statement added after round 1), 27 statements had reached 'strong agreement' (n = 25, 2, 0 for each round, respectively), a single statement achieved 'agreement' only (round 3), and 'no agreement' could be reached for 3 statements (response rate 98% for each round). Subsequently, 28 statements were adopted into the National MDT Guidelines for HNSCCUP. CONCLUSIONS: The described methodology demonstrated an effective multi-phase strategy for the development of national practice recommendations. It may serve as a cost-effective model for future guideline development for controversial or rare conditions where there is a paucity of available evidence or where there is significant variability in management practices across a healthcare service.

Symptom-based remote assessment in post-treatment head and neck cancer surveillance: A prospective national study.

OBJECTIVES: To report the incidence of locoregional recurrence in head and neck cancer (HNC) patients under surveillance following treatment undergoing symptom-based remote assessment. DESIGN: A 16-week multicentre prospective cohort study. SETTING: UK ENT departments. PARTICIPANTS: HNC patients under surveillance following treatment undergoing symptom-based telephone assessment. MAIN OUTCOME MEASURES: Incidence of locoregional recurrent HNC after minimum 6-month follow-up. RESULTS: Data for 1078 cases were submitted by 16 centres, with follow-up data completed in 98.9% (n = 1066). Following telephone consultation, 83.7% of referrals had their face-to-face appointments deferred (n = 897/1072). New symptoms were reported by 11.6% (n = 124/1072) at telephone assessment; 72.6% (n = 90/124) of this group were called for urgent assessments, of whom 48.9% (n = 44/90) came directly for imaging without preceding clinical review. The sensitivity and specificity for new symptoms as an indicator of cancer recurrence were 35.3% and 89.4%, respectively, with a negative predictive value of 99.7% (p = .002). Locoregional cancer identification rates after a minimum of 6 months of further monitoring, when correlated with time since treatment, were 6.0% (n = 14/233) <1 year; 2.1% (n = 16/747) between 1 and 5 years; and 4.3% (n = 4/92) for those >5 years since treatment. CONCLUSIONS: Telephone assessment, using patient-reported symptoms, to identify recurrent locoregional HNC was widely adopted during the initial peak of the COVID-19 pandemic in the United Kingdom. The majority of patients had no face-to-face reviews or investigations. New symptoms were significantly associated with the identification of locoregional recurrent cancers with a high specificity, but a low sensitivity may limit symptom assessment being used as the sole surveillance method.

Acute paediatric mastoiditis in the UK before and during the COVID-19 pandemic: A national observational study.

OBJECTIVES: To explore the impact of COVID-19 on the management and outcomes of acute paediatric mastoiditis across the UK. DESIGN: National retrospective and prospective audit. SETTING: 48 UK secondary care ENT departments. PARTICIPANTS: Consecutive children aged 18 years or under, referred to ENT with a clinical diagnosis of mastoiditis. MAIN OUTCOME MEASURES: Cases were divided into Period 1 (01/11/19-15/03/20), before the UK population were instructed to reduce social contact, and Period 2 (16/03/20-30/04/21), following this. Periods 1 and 2 were compared for population variables, management and outcomes. Secondary analyses compared outcomes by primary treatment (medical/needle aspiration/surgical). RESULTS: 286 cases met criteria (median 4 per site, range 0-24). 9.4 cases were recorded per week in period 1 versus 2.0 in period 2, with no winter increase in cases in December 2020-Febraury 2021. Patient age differed between periods 1 and 2 (3.2 vs 4.7 years respectively, p < 0.001). 85% of children in period 2 were tested for COVID-19 with a single positive test. In period, 2 cases associated with P. aeruginosa significantly increased. 48.6% of children were scanned in period 1 vs 41.1% in period 2. Surgical management was used more frequently in period 1 (43.0% vs 24.3%, p = 0.001). Treatment success was high, with failure of initial management in 6.3%, and 30-day re-admission for recurrence in 2.1%. The adverse event rate (15.7% overall) did not vary by treatment modality or between periods 1& 2. CONCLUSION: The COVID-19 pandemic led to a significant change in the presentation and case mix of acute paediatric mastoiditis in the UK.

Remote triage incorporating symptom-based risk stratification for suspected head and neck cancer referrals: A prospective population-based study.

BACKGROUND: Remote triage for suspected head and neck cancer (HNC) referrals was adopted by many institutions during the initial peak of the coronavirus disease 2019 pandemic. Its safety in this population has not been established. METHODS: A 16-week, prospective, multicenter national service evaluation was started on March 23, 2020. Suspected HNC referrals undergoing remote triage in UK secondary care centers were identified and followed up for a minimum of 6 months to record the cancer status. Triage was supported by risk stratification using a validated calculator. RESULTS: Data for 4568 cases were submitted by 41 centers serving a population of approximately 26 million. These represented 14.1% of the predicted maximum referrals for this population outside of pandemic times, and this gave the study a margin of error of 1.34% at 95% confidence. Completed 6-month follow-up data were available for 99.8% with an overall cancer rate of 5.6% (254 of 4557). The rates of triage were as follows: urgent imaging investigation, 25.4% (n = 1156); urgent face-to-face review, 27.8%; (n = 1268); assessment deferral, 30.3% (n = 1382); and discharge, 16.4% (n = 749). The corresponding missed cancers rates were 0.5% (5 of 1048), 0.3% (3 of 1149), 0.9% (12 of 1382), and 0.9% (7 of 747; P = .15). The negative predictive value for a nonurgent triage outcome and no cancer diagnosis was 99.1%. Overall harm was reported in 0.24% (11 of 4557) and was highest for deferred assessments (0.58%; 8 of 1382). CONCLUSIONS: Remote triage, incorporating risk stratification, may facilitate targeted investigations for higher risk patients and prevent unnecessary hospital attendance for lower risk patients. The risk of harm is low and may be reduced further with appropriate safety netting of deferred appointments. LAY SUMMARY: This large national study observed the widespread adoption of telephone assessment (supported by a risk calculator) of patients referred to hospital specialists with suspected head and neck cancer during the initial peak of the coronavirus disease 2019 pandemic. The authors identified 4568 patients from 41 UK centers (serving a population of more than 26 million people) who were followed up for a minimum of 6 months. Late cancers were identified, whether reviewed or investigated urgently (0.4%) or nonurgently (0.9%), but the overall rate of harm was low (0.2%), with the highest rate being seen with deferred appointments (0.6%).

Repeat limited fasciectomy is a safe and effective treatment for recurrence of Dupuytren's disease.

AIMS: The results of surgery for Dupuytren's disease can be compromised by the potential for disease recurrence and loss of function. Selecting which patients will benefit from repeat surgery, when to operate, and what procedure to undertake requires judgement and an understanding of patient expectations and functional needs. We undertook this study to investigate patient outcomes and satisfaction following repeat limited fasciectomy for recurrent Dupuytren's disease. METHODS: We prospectively identified all patients presenting with recurrence of Dupuytren's disease who were selected for surgical treatment with repeat limited fasciectomy surgery between January 2013 and February 2015. Patients were assessed preoperatively, and again at a minimum of five years postoperatively. We identified 43 patients who were carefully selected for repeat fasciectomy involving 54 fingers. Patients with severe or aggressive disease with extensive skin involvement were not included; in our practice, these patients are instead counselled and preferentially treated with dermofasciectomy. The primary outcome measured was change in the Michigan Hand Outcomes Questionnaire (MHQ) score. Secondary outcomes were change in finger range of motion, flexion contracture, Semmes-Weinstein monofilament (SWM) values, and overall satisfaction. RESULTS: There was a significant improvement in MHQ scores, across all domains, with a mean overall score increase of 24 points (p < 0.001). The summed flexion contracture across the metacarpophalangeal joint (MCPJ) and the proximal interphalangeal joint (PIPJ) reduced from means of 72.0° (SD 15.9°) to 5.6° (SD 6.8°) (p < 0.001). A significant increase in maximal flexion was seen at the MCPJ (p < 0.001) but not the PIPJ (p = 0.550). The mean overall satisfaction score from the visual analogue scale was 8.9 (7.9 to 10.0). Complications were uncommon although five fingers showed reduced sensibility at final follow-up. CONCLUSION: Our study shows that repeat limited fasciectomy for selected patients presenting with recurrence of Dupuytren's disease can be an effective and safe treatment resulting in excellent patient-reported outcomes and levels of satisfaction.

Surgery with the Motec total wrist replacement: learning from earlier designs.

The design of and applications for wrist arthroplasty continue to evolve but lag behind the results for hip and knee arthroplasty with respect to demonstrable durability and effectiveness. As we develop our knowledge, experience and the indications for wrist replacement surgery, it is important that we learn from past design and surgical experience. We report the case of a female patient treated with a Motec cementless metal-on-metal wrist replacement (Swemac Orthopaedics AB, Linköping, Sweden) for post-traumatic arthritis of the radiocarpal joint. Based on our experience with this case and others, we make two specific technical recommendations to improve the success and longevity of this implant.

Dissolvable intranasal haemostatic agents for acute epistaxis: A systematic review and meta-analysis.

INTRODUCTION: Nasal packing is the mainstay of epistaxis management; however, packs cause patient discomfort and can lead to hospital admission. Absorbable haemostats provide clotting factors or act as a substrate to stimulate clotting and represent a potential treatment alternative. A systematic review was performed to evaluate the efficacy of topical haemostats in the management of epistaxis. METHODS: A systematic literature search of 7 databases was performed. Only eligible randomised controlled trials (RCTs) and observational studies were included. The primary outcome was short-term haemostatic success (<7 days). Secondary outcomes included long-term haemostatic control (no rebleeding 7-30 days), patient discomfort and adverse effects. Meta-analysis was performed where possible. RESULTS: Of 2249 records identified, 12 were included in the qualitative synthesis and 4 RCTs were included in meta-analysis. The following haemostats were reported: gelatin-thrombin matrix (n = 8), aerosolised/gel tranexamic acid (n = 1), cellulose agents (n = 2) and fibrin sealants (n = 1). Studies involving tranexamic acid on removable delivery devices (eg, pledgets) were excluded. There was heterogeneity in outcome measures and inclusion criteria (coagulopathies/anticoagulants were excluded in 3 RCTs and 2 observational studies). The short-term haemostatic success varied between studies (13.9% to 100%). No significant post-procedural complications were reported. The meta-analysis favoured absorbable haemostatic agent versus packing (risk ratio 1.20; 95% confidence interval 1.05 to 1.37; P = .007). The risk of bias across all studies was moderate to high. CONCLUSIONS: The evidence suggests haemostatic agents are effective at managing acute epistaxis when compared with nasal packing. More data are required before recommendations can be made regarding management in patients on anticoagulants.
