AI-based autocontouring products claim to be able to segment organs with accuracy comparable to humans. We compare the geometric and dosimetric performance of three AI-based autocontouring packages (Autocontour 2.5.6, (“RF”); Annotate 2.3.1, (“TP”) and RT-Mind_AI 1.0, (“MM”)) in the head and neck region.

We generated 14 organ at risk (OAR) autocontours on 13 computed tomography (CT) image sets. They were compared with clinical (human-generated) contours. The geometric differences were quantified by calculating Dice coefficients and Hausdorff distances. The autocontours were compared visually with the clinical controus by an expert physician. The autocontour sets were also ranked for accuracy by two physicians. The dosimetric effects were evaluated by recalculating treatment plans on the autocontoured CT sets.

RF and TP slightly outperformed MM in geometric metrics (the percentage of OARs having mean Dice coefficients > 0.7 was RF 57.1 %, TP 64.3 % and MM 50.0%). The physician judged RF and TP contours to be more anatomically accurate, on average, than the manual contours (manual contour mean accuracy score 2.49, RF 2.28, MM 3.24, TP 1.93). The mean scores given to the autocontours by the two physicians were better for RF and TP, compared to MM (RF 1.86, MM 2.36, TP 1.77). The dosimetric differences were similar for all three programs and were not strongly correlated with the geometric differences.

The performance of the three autocontouring packages in the head and neck region is similar, with TP and RF slightly outperforming MM. The correlation between geometric and dosimetric metrics is not strong, and dosimetric evaluation is therefore recommended before clinical use of autocontouring software.

Palatine tonsil squamous cell carcinoma can be diagnosed with either tonsillectomy or tonsil biopsies. Biopsies are quicker to perform, less invasive, and provide potentially quicker results. Tonsillectomy minimises risk of missed pathology, but with greater associated morbidity. We compared whether tonsillectomy or biopsy affected surgical margin status at subsequent resection.

Our Business Intelligence Team provided a list of all patients with a primary tonsil squamous cell carcinoma who underwent surgery as their primary treatment modality in the last five years at University Hospitals Bristol. Demographic and treatment details were collected along with margin status following surgical resection.

Of the 31 patients that met inclusion criteria, 16 had biopsies and 15 had diagnostic tonsillectomies. The group who underwent tonsillectomy had a reduced risk of close or involved margins (< 5 mm) at subsequent curative-intent surgery (p < 0.001).

Our results suggest that tonsillectomy is associated with reduced likelihood of close or involved margins at subsequent curative-intent surgery. We hope this work can prompt larger multicentre comparisons between these two groups to investigate this relationship in more detail.

Oncological and functional outcomes for T1-2 N0-1 (TNMv8) p16-positive oropharyngeal squamous cell carcinoma patients were analysed according to treatment: either transoral robotic surgery (TORS) (Surgery group – TORS and neck dissection ± adjuvant radiotherapy/chemoradiotherapy) or primary radiotherapy/chemoradiotherapy (Oncology group).

Single-centre retrospective observational study.

The two-year disease-free survival rate was 88 per cent for the Oncology group (n = 42) and 95 per cent for the Surgery group (n = 44). The two-year overall survival rate was 98 per cent for the Oncology group and 100 per cent for the Surgery group. The functional swallowing outcome at two years post-treatment was similar in both groups. Subgroup analysis showed patients treated with surgery-only with no adjuvant treatment had the best functional outcome whilst patients treated with surgery and post-operative chemoradiotherapy had the worst functional outcome.

The overall oncological and functional outcomes at two years were similar in both groups. Patients treated with surgery-only had the best functional outcome without compromised oncological outcome.

Dental management is critical prior to radiotherapy (RT) for head and neck cancer (HNC) but cumbersome and time intensive. This qualitative study investigates dentists’ evaluative processes to identify areas for improvement.

Semi-structured interviews were conducted with dentists involved in the care of HNC patients. The interviews were guided by the Consolidated Framework for Implementation Research and the Theoretical Domains Framework to identify factors influencing pre-RT dental management.

Five dentists were participated in the interviews. Key themes were identified through qualitative and quantitative evaluation and are as follows: Coordination among care providers, knowledge of the RT plan, visual depictions of dose distribution and understanding of the patient’s dental history.

This study demonstrates the complexity of pre-RT management and identifies key elements. Knowledge of the RT plan and improved interdisciplinary coordination represents opportunities for improvement. Visual dose prediction methods may expedite and improve pre-RT management.

Oral mucositis (OM) emerged in the late 1980s to describe the adverse effects of radiation therapy (RT) on the oral mucosa. OM is the most common and clinically significant acute adverse effect of radiotherapy for head and neck cancer. Symptoms of OM vary from pain and discomfort to an inability to tolerate food or fluids, and it may affect the quality of life, breaks in treatment, hospitalisation, and therefore cancer treatment and outcome. This study aimed to evaluate the pomegranate flower’s efficacy in preventing and treating radiation-induced mucositis due to antioxidant, anti-inflammatory and anti-cancer effects.

This phase II clinical trial was conducted on 50 patients (case and control) with head and neck malignancy. Patients in the case groups were instructed to rinse their mouths with 5 mg Pomegranate powder with 15 cc of sterile water three times a day. The patients in the control group rinsed their mouths with normal saline mouthwash, which is the most relatively accepted preventive and supportive care in this setting. The onset and degree of radiation-induced mucositis were graded during treatment, with ‘WHO mucositis grading’ and the ‘quality of life questionnaire’ (QLQ-OES18).

Forty-eight patients were analysed. There was a significant difference between the two groups on onset and severity of mucositis in the two groups. There were longer intervals for the incidence of different grades of mucositis in the case group, in comparison with the control groups (P value < 0·05). Also, Complaints of dysphagia in the case groups were lower than in the control.

Pomegranate flower seems to be effective at the time of onset, and the severity of oral mucositis during head and neck radiation. It could be a simple, potent, and inexpensive agent, which is easily available.

Mucoepidermoid carcinoma of unknown primary (MEC-UP) in the head and neck is a rare presentation of the most common salivary gland cancer. Cancers of unknown primary sites often have poorer prognoses than similar cancers with known primary. Few cases of MEC-UP have been reported; therefore, the objective of this report is an overview of the diagnosis and management of MEC-UP.

We present two patients with low-grade MEC-UP at a high-volume tertiary care institution in Ontario, and a database search returning 1560 citations of which five studies with seven MEC-UP cases were identified.

Review of the limited cases suggest many clinicians use positron emission tomography-computed tomography (PET-CT) in addition to panendoscopy and targeted biopsies with consideration for diagnostic tonsillectomy in diagnostic work-up.

Like other salivary gland cancers, primary therapeutic surgical resection is recommended with low threshold for adjuvant radiotherapy to regions at high risk for harbouring the primary malignancy, especially in cases of high-grade histopathology.

The posterior pharyngeal wall is an anatomical subsite of both the oropharynx and hypopharynx. The treatment outcomes of squamous cell carcinoma (SCC) of these sites are generally published together, which makes the interpretation of data challenging. The aim of this analysis was to determine if there is any difference in the treatment outcomes of these two rare disease entities.

Retrospetive analysis showed that the posterior pharyngeal wall was the primary subsite in 17 patients (1.65 per cent) out of 1031 patients with oropharyngeal SCC, and in 23 patients (11.73 per cent) out of 196 patients with hypopharyngeal SCC.

The five-year overall survival was 45 per cent for oropharyngeal origin and 53 per cent for hypopharyngeal origin patients. There was no significant difference in survival and locoregional control between these two groups of patients.

Squamous cell carcinoma of the posterior pharyngeal wall is a rare entity, which in our series represents 1.65 per cent of oropharyngeal cases and 11.73 per cent of hypopharyngeal tumours. There was no difference in treatment outcomes between the two groups.

Head and neck squamous cell carcinomas (HNSCCs) are aggressive tumours lacking a standardised timeline for treatment initiation post-diagnosis. Delays beyond 60 days are linked to poorer outcomes and higher recurrence risk.

A retrospective review was conducted on patients over 18 with HNSCC treated with (chemo)radiation at a rural tertiary care centre (September 2020–2022). Data on patient demographics, oncologic characteristics, treatment details and delay causes were analysed using SPSS.

Out of 93 patients, 35.5% experienced treatment initiation delays (TTIs) over 60 days. Median TTI was 73 days for delayed cases, compared to 41.5 days otherwise. No significant differences in demographics or cancer characteristics were observed between groups. The primary reasons for the delay were care coordination (69.7%) and patient factors (18.2%). AJCC cancer stage showed a trend towards longer delays in advanced stages.

One-third of patients faced delayed TTI, primarily due to care coordination and lack of social support. These findings highlight the need for improved multidisciplinary communication and patient support mechanisms, suggesting potential areas for quality improvement in HNSCC treatment management.

Salvage neck dissection for squamous cell carcinoma is performed for residual or recurrent nodal disease after chemoradiotherapy or radical radiotherapy for locally advanced head and neck cancer. Our study aims to investigate the extent to which salvage neck dissection can be safely performed in treating recurrent or residual nodal metastasis.

A retrospective analysis of 53 patients with suspected residual or recurrent nodal disease after primary treatment (January 2016 to December 2018) was performed.

Pathological confirmation of viable squamous cell carcinoma following surgery was found in 43.4 per cent of patients. Post-operative infection, accessory and vagal nerve injuries were more common in patients with dissection of levels I–V than that of levels II–IV. There was no significant difference in three-year survival rate between patients with levels II–IV dissection and that of levels I–V dissection (p = 0.84).

The extent of salvage neck dissection can be limited to reduce post-operative complications while maintaining acceptable oncological outcomes.

For over a century, circumferential pharyngoesophageal junction reconstruction posed significant surgical challenges. This review aims to provide a narrative history of pharyngoesophageal junction reconstruction from early surgical innovations to the advent of modern free-flap procedures.

The review encompasses three segments: (1) local and/or locoregional flaps, (2) visceral transposition flaps, and (3) free-tissue transfer, focusing on the interplay between pharyngoesophageal junction reconstruction and prevalent surgical trends.

Before 1960, Mikulicz-Radecki's flaps and the Wookey technique prevailed for circumferential pharyngoesophageal junction reconstruction. Gastric pull-up and colonic interposition were favoured visceral techniques in the 1960s–1990s. Concurrently, deltopectoral and pectoralis major flaps were the preferred cutaneous methods. Free flaps (radial forearm, anterolateral thigh) revolutionised reconstructions in the late 1980s, yet gastric pull-up and free jejunal transfer remain in selective use.

Numerous pharyngoesophageal junction reconstructive methods have been trialled in the last century. Despite significant advancements in free-flap reconstruction, some older methods are still in use for challenging clinical situations.

Radiation dermatitis (RD) is a frequent toxicity during radiotherapy (RT) for head and neck cancer (HNC). We report the first use of KeraStat® Cream (KC), a topical, keratin-based wound dressing, in patients with HNC receiving RT.

This pilot study randomized HNC patients treated with definitive or postoperative RT (≥60 Gy) to KC or standard of care (SOC), applied at least twice daily during and for 1-month after RT. Outcomes of interest included adherence to the assigned regimen (at least 10 applications per week of treatment), clinician- and patient-reported RD, and skin-related quality of life.

24 patients were randomized and completed the study. Most patients had stage III-IV disease and oropharynx cancer. Median RT dose was 68 Gy; the bilateral neck was treated in 19 patients, and 18 patients received concurrent chemotherapy. Complete adherence was observed in 7/12 (SOC) vs. 10/12 (KC, p = 0.65).  Adherence by patient-week was 61/68 versus 64/67, respectively (p = 0.20). No differences in RD were observed between groups.

A randomized trial of KC versus SOC in HNC patients treated with RT is feasible with good adherence to study agent. An adequately powered randomized study is warranted to test the efficacy of KC in reducing RD.

This study investigates the impact of primary care utilisation of a symptom-based head and neck cancer risk calculator (Head and Neck Cancer Risk Calculator version 2) in the post-coronavirus disease 2019 period on the number of primary care referrals and cancer diagnoses.

The number of referrals from April 2019 to August 2019 and from April 2020 to July 2020 (pre-calculator) was compared with the number from the period January 2021 to August 2022 (post-calculator) using the chi-square test. The patients’ characteristics, referral urgency, triage outcome, Head and Neck Cancer Risk Calculator version 2 score and cancer diagnosis were recorded.

In total, 1110 referrals from the pre-calculator period were compared with 1559 from the post-calculator period. Patient characteristics were comparable for both cohorts. More patients were referred on the cancer pathway in the post-calculator cohort (pre-calculator patients 51.1 per cent vs post-calculator 64.0 per cent). The cancer diagnosis rate increased from 2.7 per cent in the pre-calculator cohort to 3.3 per cent in the post-calculator cohort. A lower rate of cancer diagnosis in the non-cancer pathway occurred in the cohort managed using the Head and Neck Cancer Risk Calculator version 2 (10 per cent vs 23 per cent, p = 0.10).

Head and Neck Cancer Risk Calculator version 2 demonstrated high sensitivity in cancer diagnosis. Further studies are required to improve the predictive strength of the calculator.

This study analyses outcomes for 660 patients managed via a novel telescopic pathway for suspected head and neck cancer referrals.

Data were collected prospectively between January 2021 and December 2022, capturing all two-week-wait referrals triaged as low risk and managed via a nurse-led clinic for nasendoscopic examination and consultant-led remote assessment.

In total, 660 patients were included. There were six head and neck cancers diagnosed, giving a conversion rate of 0.9 per cent. Mean (standard deviation) time to informing the patient whether they did or did not have cancer (28-day faster diagnosis standard) was 28.6 days (20.2), with no significant difference observed in patients imaged prior to review (p = 0.63). No missed cancers were detected in the follow-up period.

Low-risk head and neck cancer referrals can be safely managed in a nurse-led clinic for recorded examination with asynchronous consultant-led management. Further work is required to ensure adherence to the new faster diagnosis standard.

Developing skills in rigid endoscopy poses challenges to the surgical trainee. This study investigates whether a modified manikin can improve the technical skill of junior operators by providing direct quantitative feedback.

A force-sensing pad was incorporated into the oral cavity of a life support manikin. Junior trainees and senior otolaryngologists were invited to perform rigid endoscopy and received real-time feedback from the force sensor during the procedure.

There was a significant inverse correlation between operator seniority and the weight applied to the oral cavity (p < 0.0001). All junior trainee operators applied less weight after five attempts (346 ± 90.95 g) compared to their first attempt (464 ± 85.79 g). This gave a statistically significant decrease of 118 g (standard deviation = 107.27 g, p = 0.007) when quantitative feedback was provided to learning operators.

This low-cost, simple model allows trainees to rehearse a high-risk procedure in a safe environment and adjust their operative technique.

A pathological communication between the trachea and oesophagus – a tracheoesophageal fistula – may be congenital or acquired, benign or malignant, necessitating a multidisciplinary approach. Conservative attempts at closure of this abnormal connection are ineffective; the interposition of healthy vascular tissue offers the least chance of recurrence.

Outcomes of an islanded fasciocutaneous internal mammary artery perforator flap applied for tracheoesophageal fistula management were assessed in four radiated patients with laryngeal carcinoma using retrospective records.

Four male patients, with an average age of 60.75 years, underwent tracheoesophageal fistula closure between September 2017 and February 2021. A left-sided second internal mammary artery perforator flap was used in all cases, with an average dimension of 10.5 × 4.5 cm. There were no complications of tracheoesophageal leak, flap issues or donor site morbidity on follow up.

Recent advances in angiosomal territory mapping and microvascular dissection techniques, combined with an understanding of tracheoesophageal fistula pathology, have changed management perspectives in these difficult-to-treat patients.
