Prognostic scores in laryngeal cancer.

PURPOSE: To evaluate the utility of various pre-treatment prognostic scoring systems for overall survival (OS) in laryngeal cancer, including neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), modified Glasgow Prognostic Score (mGPS) and systemic immune-inflammatory index (SIII). METHODS: We undertook a retrospective 5-year study of 220 patients with laryngeal squamous cell carcinoma undergoing active treatment. RESULTS: On multivariate analysis, low NLR (≤ 2.415, p = 0.001, OR 3.851), low PLR (≤ 269.855, p = 0.002, OR 5.520), high LMR (> 2.225, p < 0.001, OR 0.458) and low SIII (≤ 1144.465, p = 0.003, OR 3.673) were significantly associated with improved OS, accounting for confounding factors of tumour subsite, T-stage and performance status. C-reactive protein (CRP) alone (p = 0.264) and mGPS (p = 0.350) were not significantly associated with OS. CONCLUSIONS: NLR, PLR, LMR and SIII represent inexpensive, easily obtainable adjuvant decision-making tools which could help tailor individualised treatment regimes. Further investigation into the utility of combination scores and the role of different laryngeal subsites may be of interest.

Diagnostic accuracy outcomes of office-based (outpatient) biopsies in patients with laryngopharyngeal lesions: A systematic review.

BACKGROUND: In-office biopsies (IOB) using local anaesthetic for laryngopharyngeal tumours has become an increasingly popular approach since the advent of distal chip endoscopes. Although a wide range of studies advocate use in clinical practice, the widespread application of the procedure is hampered by concerns regarding diagnostic accuracy. OBJECTIVE: To assess the diagnostic accuracy of IOB performed via flexible endoscopy. In addition, to analyse modifiable factors that may affect diagnostic accuracy of IOB. DESIGN: A systematic review following the PRISMA guidelines was conducted. PubMed, EMBASE, the Cochrane Library, Web of Science and CINAHL were used in the literature database search. Quality assessment of included studies was perfomed using the Newcastle-Ottawa Scale. RESULTS: A total of 875 studies were identified, 16 of which were included into the systematic review; 1572 successful biopsies were performed using flexible endoscopy; 1283 cases were accurately diagnosed in the outpatient setting (81.6%) and 289 samples did not provide an accurate diagnosis (18.4%). The median sensitivity of IOB was 73%, and the specificity was 96.7%. Analysis of variable factors did not show any significant differences in method of approach, size of equipment (forceps) and additional lighting system or learning curve. CONCLUSION: IOB are a viable tool for diagnostic workup of laryngopharyngeal tumours. Clinicians should be wary of reported limitations of IOB when benign or pre-malignant diagnoses are made. In cases suspicious of malignancy, confirmatory investigation should be conducted.

Patterns of urgent hoarseness referrals to ENT-When should we be suspicious of cancer?

BACKGROUND: Current UK referral criteria stipulate that hoarseness should be persistent to merit 2 week wait (2WW) or urgent suspicion of cancer (USOC) referral. This study delineates patterns of hoarseness presentation with a view to assisting referral pathways, and whereby reassurance could be provided. METHODS: A pre-existing database of patients referred with hoarseness under the urgent suspicion of cancer (USOC) category was analysed. Univariate and multivariate analyses were performed on a variety of demographic and comorbid features to produce odds ratios (OR) of features either related or not related to laryngeal cancer. RESULTS: Of 698 consecutive hoarseness referrals were studied. In these referrals there were 506(73%) with persistent hoarseness and 192(27%) with intermittent hoarseness. The most significant patient variables related to laryngeal cancer were persistent hoarseness (OR 4.97), recreational drug use (OR 4.94), male gender (OR 4.01) and weight loss (OR 3.75). Significant patient variables present not related to laryngeal cancer diagnosis were intermittent hoarseness (OR 0.2), the presence of cough (OR 0.2), globus sensation (OR 0.25) and recent viral infection (OR 0.29). CONCLUSION: The strongest association with cancer is seen in patients that are persistently hoarse. Patients with fluctuating hoarseness do not need an "urgent suspicion of cancer" referral. Additional demographic referral information could help to streamline the referral of these patients, and reassure others.

An open structure questionnaire on reasons for delay in presentation: a study of patients attending clinic with red flag symptoms of head and neck cancer.

PURPOSE: Reasons for delayed presentation in cancer are reported as patient or professional delays. Studies have examined patient demographic factors associated with presentation delay, but it is currently unknown why patients feel they delayed presenting. METHODS: Questionnaire study of consecutive patients attending an urgent suspicion of cancer clinic at a tertiary referral centre in Glasgow over a 3-month period. RESULTS: 395 patients were included. 53 (13%) patients waited 0-7 days, 164 (41%) patients 1-4 weeks, 139 (35%) 1-12 months and 31 (8%) waited longer than 12 months, before presenting. 8 (3%) did not state length of time before presentation. 123 (31%) patients were not worried about their symptoms. 5 of the 13(38%) patients diagnosed with head and neck cancer, waited up to 12 months. 5 (38%) cancer patients delayed presentation because they were not worried about symptoms. CONCLUSION: Patients with head and neck cancer are not worried about their symptoms and delay their presentation, possibly contributing towards later stage diagnosis.

Patterns of hospital admission in 54 501 patients with epistaxis over a 20-year period in Scotland, UK.

BACKGROUND: Epistaxis affects most people over their lifetime. It is the commonest ear, nose and throat emergency. Hospital admission and socio-economic deprivation have been associated with mental health disorders, respiratory illness and with emergency hospital admissions. Low socio-economic status has never previously been associated with epistaxis, a common reason for admission to ear, nose and throat departments throughout the UK. METHODS: Demographics from Information Services Division Scotland were analysed over a period of 20 years. This focused on gender, number of admissions, number of bed days, socio-economic deprivation (Scottish Index of Multiple Deprivation) and mortality within 1 year. RESULTS: Data from 54 501 patients were assessed. Admission numbers and length of stay have significantly decreased (P < 0.0001). Males are more frequently affected (P = 0.001). Admission numbers were higher for patients in more deprived areas (P < 0.001). Mean duration of stay has decreased by 1 bed day. Surgical intervention of epistaxis has increased significantly (P < 0.001). There is an associated 1-year mortality rate of 9.8% following epistaxis. CONCLUSION: There has been a significant decrease in hospital admissions and length of hospital stay in patients admitted with epistaxis over the past 20 years. There is a significant association with deprivation and epistaxis admission.

Cytological accuracy and radiological staging in patients with thyroid cancer in Glasgow.

To assess the accuracy of initial combined cytological accuracy and radiological staging of patients suspected of having thyroid malignancy with their final histopathology. Retrospective case series in a tertiary referral centre for head and neck malignancy. All patients with malignant thyroid cytology and cytology suspicious for malignancy, between the dates of June 2010 and July 2014, were included. The pre-operative staging was compared against the final histological staging. Demographics and outcomes for each patient were recorded. Sixty-five patients were recorded in this group. 20 (30.7 %) were male. The mean age at presentation was 51 years (SD 16.8 years). 39 (60 %) patients were aged over 45 years. Fine needle aspiration cytology (FNAC) was performed in all patients and was Thy 4 in 40 (62 %) and Thy 5 in 25 (38 %). Following surgery or subsequent biopsy, FNAC was found to be accurate in 38/40 (Thy 4) and 25/25 (Thy 5) cases in diagnosing malignancy, with Thy 4 yielding 95 % malignancy and Thy 5 % 100 %. Fifty-eight patients underwent a surgical procedure for thyroid cancer. Two further patients had a diagnostic hemi-thyroidectomy for later proven benign disease. Five patients due to medical co morbidities, inoperable disease or refusal of surgery were managed non-surgically. In the surgical group 16 patients underwent a diagnostic hemi-thyroidectomy and 11 of these required a completion thyroidectomy. Forty-six patients underwent total thyroidectomy. Forty-six patients underwent a neck dissection: 27 prophylactic central compartment neck dissections and 19 planned therapeutic neck dissections were performed. Radiological staging correctly predicted final pathological TNM staging in 25 (43 %) patients. 27 (47 %) patients had radiological staging which under staged their final histological staging and 6 (10 %) patients had scans that over staged their cancer. Of those that were under staged, 15 (56 %) had their nodal disease under staged (following prophylactic central neck dissection). Radiological staging comprised ultrasound (n = 58) and CT scanning (n = 45/58 pre-operatively). Pre-operative staging in thyroid cancer should include cytology, ultrasound and CT scanning. Unless low-risk papillary thyroid cancer is suspected pre-operatively, patients with Thy 4 cytology can be given the offer of a total thyroidectomy as surgical management.

Insomnia, depression and anxiety in patients urgently referred with suspicion of head and neck cancer.

OBJECTIVE: To determine differences in insomnia, depression and anxiety between ENT patients with benign and malignant conditions prior to and after an urgent suspicion of cancer appointment. METHODS: Out-patients with urgent suspicion of cancer completed three psychometric questionnaires prior to their appointment and at two to four weeks post-diagnosis. RESULTS: There was no significant difference in questionnaire scores between malignant and benign patients prior to the patients' appointments (p > 0.05 for all questionnaires). In benign patients, there was significant improvement in scores for all questionnaires (p < 0.01) and in malignant patients there was significant worsening of scores for all questionnaires (p < 0.01) at follow-up appointments. CONCLUSION: Prior to appointments, patients with benign and malignant conditions experienced similar levels of insomnia, depression and anxiety. Following diagnosis, cancer patients had significantly poorer scores, indicating worsening of these symptoms. In patients with benign diagnoses, all questionnaire scores improved, indicating resolution of their symptoms and possible association between the appointment and their baseline scores.

National survey sampling exercise on current practice in channelled local anaesthetic biopsy in suspected head and neck cancer.

OBJECTIVE: Out-patient channelled endoscopic local anaesthetic biopsy reduces the time to diagnosis and wider use may improve cancer pathway times. This study aimed to assess the practice of ENT surgeons using channelled local anaesthetic biopsy. METHOD: A survey was distributed nationally, containing questions about out-patient local anaesthetic biopsy. RESULTS: In total, 58 responses were returned; only 12 per cent of respondents (n = 7) used general anaesthetic biopsy. The advantages of local anaesthetic biopsy were: the avoidance of general anaesthetic for patients with poor performance scores (95 per cent, n = 55) and faster cancer pathway times (91 per cent, n = 53). Disadvantages were: clinics running late (29 per cent, n = 17) and complications (24 per cent, n = 14). The main barrier to using local anaesthetic was access to channelled flexible endoscopy (38 per cent, n = 22), with 43 per cent (n = 25) reporting they were not using out-patient channelled endoscopes but would be interested in using them. CONCLUSION: Surgeons are interested in using channelled endoscopic local anaesthetic biopsy, but they are limited by access to equipment. Increased use of channelled endoscopes may improve national cancer pathway times and avoid challenging general anaesthetics.

Prospective cohort study assessing patient satisfaction and diagnostic accuracy in channeled endoscope local anesthetic biopsy in the investigation of head and neck cancer.

BACKGROUND: There are delays in the head and neck Urgent Suspicion of Cancer (USOC) pathway. Local anesthetic (LA) biopsy with channeled endoscopes in outpatients can reduce time to diagnosis. METHODS: Questionnaire-based prospective study of LA or general anesthetic (GA) biopsy for investigation of cancer from September 2021 to July 2022. RESULTS: 100% (n = 48) were very satisfied or satisfied with their overall experience. 71% (n = 20) of LA patients reported they would prefer to have a biopsy under LA. LA biopsy was 68% sensitive and 100% specific for cancer diagnosis. 28.6% (8) and 10% (2) of LA and GA patients had palliative MDT outcomes. Median time to diagnosis was 44.5 and 49.0 days for LA and GA biopsy, respectively. CONCLUSION: LA biopsy had a high satisfaction rate and is sensitive for diagnosing cancer. LA biopsy can expedite treatment pathways. LA biopsy should be considered as an option for first line investigation.

A decade of laryngeal dysplasia in Paisley, Scotland.

Laryngeal dysplasia is a known premalignant condition. A recent consensus statement by otorhinolaryngologists and pathologists on the diagnosis and management of laryngeal dysplasia Mehanna et al. (Clin Otol 35:170-176, 2010) identified a need for retrospective data on epidemiological aspects of laryngeal dysplasia as well as responses to treatment. A retrospective search was made on the hospital pathology database for cases of laryngeal dysplasia. Searches were made under "Larynx", "Dysplasia", "Carcinoma in situ" and "Vocal Cord". The search dates were between 1998 to the present day. The returned records were checked with the pathology reports and the case notes of these patients requested for analysis. A proforma was completed for each patient with laryngeal dysplasia. These patients were then anonymised, entered into a spreadsheet and analysed. The initial search returned 937 patients. Of these patients, 505 (54%) had benign laryngeal pathology, 131 (14%) had laryngeal dysplasia and 301 (32%) had invasive cancer on biopsy. Patients who developed malignancy within 3 months of being diagnosed with laryngeal dysplasia were excluded. This left 110 patients for analysis. Of the dysplastic patients, 40 (36%) had mild dysplasia, 31 (28%) had moderate dysplasia and 39 (35%) had severe dysplasia/carcinoma in situ; 70% were male. The median age was 63 (min 21, max 90, ave 62.5); 74 (67%) were smokers or ex-smokers. Progression of dysplasia was seen in 7 (6%) patients. Malignant transformation was seen in 18 (16%) patients. The average time for malignant change was 43 months (min 4 months, max 192 months and median 15.5 months; 73 (66%) patients were treated by microlaryngeal resection, 2 (2%) were treated by vocal cord stripping, 28 (25%) were treated by endolaser therapy, and 1 (1%) patient was treated by using the microdebrider skimming blade and 6 (5%) were treated by radiotherapy. Cure of dysplasia or downgrading of severity in these treatment subgroups was 62 (85%), 2 (100%), 24 (86%), 1 (100%) and 4 (66%), respectively. Our study reiterates that laryngeal dysplasia carries a significant risk of developing malignancy. Management of this condition varies widely. Endolaser resection is becoming more frequently employed in the UK. Our study is biased heavily towards cold steel dissection. Although there is increasing practice in the UK to promote early discharge, we feel it may be safer to keep patients under surveillance for longer periods. Despite this, all patients who returned after discharge or failing to attend with invasive cancer did so with new symptoms.

Palliation of head and neck cancer: a review of the unique difficulties.

Each year, there are 11 900 new diagnoses of head and neck cancers in the UK, with around 4000 deaths. Survival rates are higher for those diagnosed earlier, however, patients are often diagnosed later, with 20% palliative at the time of diagnosis. There is a scarcity of head and neck cancer palliative care literature available. This review article aims to discuss the unique challenges of head and neck cancer palliation. It specifically focusses on the challenges of pain management, airway obstruction, dysphagia, haemorrhage and the psychology of palliative head and neck cancer management. This article explores the advantages and disadvantages of many of the different treatment options available. It is hoped that this article will highlight the unique difficulties encountered by patients with head and neck cancer towards the end of their life and offer insights and suggestions to improve patients' quality of life in their final weeks and months.

Does recreational drug use influence survival and morbidity associated with laryngeal cancer.

Background: The use of opioids is considered a risk factor for laryngeal cancer. A retrospective study was performed to explore the relationship between recreational drug exposure and laryngeal cancer. Methods: Patients diagnosed between the 1st of January 2013 and the 31st of December 2017 using ICD-10 CD-32 coding were identified from the Head and Neck Multidisciplinary Team database. We divided the study population into two cohorts (RD and non-RD) and compared the demographics, morbidity, and outcomes of these two populations. In addition, we performed case-matched analysis to control for potential confounding factors including gender, alcohol use and cigarette smoking. Findings: 329 patients in Glasgow, Scotland were included with a mean age of 64.96 ± 10.94 and a follow-up of 24 ± 13.91 months. Of these, 39 reported recreational drug use (RD). RD was associated with younger age (53.0 vs. 66.6, p<0.001) at diagnosis with laryngeal cancer. A greater proportion of tumours occurred in the supraglottic subsite (p=0.041). Furthermore, these patients were more likely to undergo tracheostomy (RR=2.50, 95% CI: 1.41-4.44, p=0.008) and laryngectomy (RR=2.25, 95% CI: 1.57-3.21, p<0.001). Recreational drug users were more likely to require enteral feeding support (RR= 1.44, 95% CI: 1.13-1.84, p=0.02) during oncological treatment. No survival differences were noted at 1, 2, or 3-years (plog-rank=0.83). Case matched analysis correcting for smoking, alcohol and gender confirmed that recreational drug users were younger at diagnosis with a predilection for the supraglottic subsite. Conclusion: Recreational drug use is associated with an increased burden of disease and morbidity in laryngeal cancer. We suggest that clinicians view recreational drug exposure as a red flag in those with suspected laryngeal cancer regardless of patient age.

Managing children with sialorrhoea (drooling): Experience from the first 301 children in our saliva control clinic.

OBJECTIVES: Sialorrhoea (drooling) is defined as the involuntary escape of saliva from the mouth. It is considered normal in young children but may cause social problems in older children. Sialorrhoea is frequently seen in children with cerebral palsy, with rates between 10% and 58% and in other neurodevelopmental diseases. Management of these children can be challenging and often requires an individual and stepwise approach. This is a large case series of children managed at the saliva control clinic in Glasgow, Scotland. METHODS: A chart review of all children attending the saliva control clinic between 2006 and June 2012 was performed. This was to ensure that all children would have long term follow up (3 years minimum). Drooling severity was assessed on the child's first attendance at clinic, and at review following a treatment option, using the Teacher Drooling Scale (TDS). RESULTS: The total number of children attending this clinic was 301, of which 274 had adequate records for inclusion in the study. 176 (64%) were male. The mean age was 7.3 (median 5) years. In terms of development 35 (13%) of children were developing normally and 50 (18%) had general developmental delay. There were 105 (38%) children with cerebral palsy. The final management of sialorrhoea in these children was simple reassurance and advice for 34 (12%), speech and language therapy for 62 (23%) anticholinergics in 90 patients (33%), botox for 30 (11%) and surgery for 71 (26%) children. The rate of non-tolerance of anticholinergics is 30%; 90 of the 298 children tried on anticholinergics had side effects leading to the treatment being stopped. The average teachers drooling score was 4.24 before clinic and 1.59 after clinic. Satisfactory results were achieved in 215 (78%) of children. CONCLUSION: Our data illustrates that effective patient management requires all treatment options to be available, including speech therapy, medications, botulinum toxin and surgery. This is one of the larger case series of children attending a saliva control clinic.

Botulinum toxin A for children with salivary control problems.

OBJECTIVE: The aim of this study was to review the response of children who have received botulinum toxin A (BtA) injections for saliva control in our institution. METHODS: Retrospective case series of children attending a saliva control clinic in a paediatric tertiary referral hospital. Children were identified from the saliva control database, which has been in place since its creation in 2006. Prior to receiving BtA all the children in the study had previously undertaken a 3-month trial of pharmacological therapy, with no effect. All BtA injections were performed freehand to the parotid and submandibular glands. The background diagnosis, comorbidities for the child, age at presentation, dose of BtA, the response, and any complications were recorded. RESULTS: 97 children were identified and 175 BtA doses were given (median per child: 1, mean: 1.9). 59 (61%) were male. The age range was between 2 months and 18 years (mean 8.6 years, median 8.8 years). The dose injected varied between 0.52 units/kg and 21.28 unit/kg (mean 5 units/kg, median 4.2 units/kg). These were performed using local anaesthetic on 131 (75%) occasions. The remainder were performed under general anaesthetic. Responses to BtA were classed as effective 109 (62%), partially effective 14 (8%) or not effective 50 (29%). The response duration was between 0.25 and 18 months (mean 4 months). Complications were seen following 22 injections (10.9%). Data modelled using binary logistic regression found that male gender and children with cerebral palsy are statistically predicted to have a better response to BtA. CONCLUSION: Botulinum A injected under local anaesthetic is a safe, effective treatment for children with sialorrhoea. Ultrasound guidance is not necessary as long as anatomical landmarks are used for placement. The main adverse effect that can result is dysphagia, which is of concern in children that can swallow independently prior to injection. Male sex and cerebral palsy are statistically independent positive predictive factors for successful outcome of BtA injections for sialorrhoea, however this does not preclude other children from receiving or benefitting from it. Children that respond well to BtA initially, are likely to respond well in the future.

Osteocutaneous radial forearm free flap in subtotal nasal reconstruction.

A 66-year-old man presented with a large squamous cell carcinoma of the right nasal vestibule. He underwent partial rhinectomy and medial maxillectomy followed by staged reconstruction. Reconstruction of a full-thickness nasal defect requires repair of three distinct layers: the skin-soft tissue envelope, subsurface framework and intranasal lining. We report the first use in the UK of an osteocutaneous radial forearm free flap in the reconstruction of a subtotal nasal deficit. The skin of the radial forearm free flap was tubed to recreate the nasal lining and the radial bone reconstructed the dorsal contour of the nose. A full-thickness paramedian forehead flap supplied external coverage. The osteocutaneous radial forearm free flap and forehead flap is a viable option for large nasal defects requiring reconstruction of framework, nasal lining and external covering.

Treatment of tracheomalacia with aortopexy in children in Glasgow.

OBJECTIVE: The aim of this study was to assess outcomes of infants and children undergoing aortopexy and to try and establish which children would derive the greatest benefit from this complex intervention. Materials and METHODS: This is a retrospective case series in a pediatric tertiary referral hospital between 1993 and 2012. A case sheet review was performed to collect demographic data and identify outcomes for each child. The effects of the subtype of tracheomalacia, weight at surgery, symptoms at presentation, surgical approach, and preoperative ventilation were considered. RESULTS: There were 30 children who underwent aortopexy during the study period. Of the 30 children in the study, 21 children (70%) were male. The gestational age at birth ranged between 25 and 41 weeks (9 children [30%] were preterm). Age at surgery was between 2 and 140 weeks (mean; 31.5 weeks, median; 26 weeks). The onset of symptoms was between birth and 18 months (mean; 3.8 months, median; 3.5 months). The presenting symptoms were stridor (n = 9; 30%), failed extubation (n = 4; 13%), death attacks (n = 8; 27%), and cyanosis (n = 9; 30%). The underlying pathology was primary in 10 children (33%) and secondary in 18 children. The diagnosis was made by bronchoscopy in 26 children (93%). Imaging was performed in 25 children (83%). Aortopexy in our institution is performed by general pediatric surgeons (n = 8; 27%) and cardiothoracic surgeons (n = 22; 73%). In the immediately postoperative period, 25 children (83%) were thriving. Of the children that required another procedure; 1 child was reintubated (3%), 2 children had a tracheostomy (6%), 1 child had a stent (3%), and 2 children died (6%). Clinical follow-up of these children was between 1 month and 12 years. Long term, in 22 children (73%) were asymptomatic. CONCLUSION: There were no clinical predictors of outcome identified, but aortopexy is a safe effective procedure for children with severe tracheomalacia.

Long-term follow-up of children after submucosal diathermy to the inferior turbinate for rhinitis.

BACKGROUND: There is currently poor evidence base to support turbinate surgery in children. Submucosal diathermy (SMD) is a day case procedure offered to children who have refractory rhinitis. There is currently no well-defined population who will benefit from this procedure. The Glasgow Children's Benefit Inventory (GCBI) is a validated questionnaire that can be used to assess benefit following an intervention. METHODS: In September 2009, questionnaires were sent by post to the parents of 70 children who underwent SMD between 2003 and 2006. If no response was received, an attempt to contact the parents by telephone was made. These questionnaires were then analysed to ascertain benefit scores. RESULTS: Returned questionnaires were received for 47 children (68%). 70% (33) felt that this had been a worthwhile procedure. Residual nasal symptoms were recorded, of which rhinorrhea was the most frequent (30, 64%), followed by nasal blockage (28, 60%). Of these children, 23 had a positive radio-allergosorbent test (RAST) and 21 were negative. Overall the median GCBI for children receiving SMD was 19.5. This was elevated in the RAST positive group (median score 27) and lower for the RAST negative group (median score 14). CONCLUSION: This study highlights some benefit to inferior turbinate study in children by using the GCBI. Improved benefit was not demonstrated significantly in older or younger children or in RAST positive or negative children. Further studies, by means of a randomised controlled trial are required to provide a better level of evidence for this procedure.
