Accurate delivery of radiotherapy to head, neck and brain cancer relies on the use of sophisticated immobilisation devices, usually using a restrictive thermoplastic mask. These masks can cause anxiety and can make treatment difficult for many patients. Open-face or maskless techniques are alternatives which can improve the patient experience. This systematic review aimed to compare the effectiveness of open-face (OF) masks and maskless surface guided radiotherapy (SGRT) with conventional masks.

Primary research papers from the last 10 years were gathered from Scopus, PUBMED, Web of Science and OVID databases. Quantitative data reporting interfractional set-up errors and intrafractional patient motion were extracted from included studies and subjected to descriptive statistical analysis. Additional qualitative data relating to patient tolerance were also extracted to inform discussion.

Ten studies were identified for inclusion. The data identified that OF masks can reproduce patient set-up with an accuracy of <2 mm and <1° and can restrict movement to <1 mm and 0·4°, while maskless SGRT can achieve accuracy to within 0·05 mm and 0·1°.

This review indicates comparable reduction of intrafractional motion between conventional masks, Open-Face masks and maskless SGRT techniques. More research is needed into the impact of maskless SGRT techniques on translational and rotational motions compared to traditional masks.

Adaptive radiotherapy (ART) is commonly used to mitigate effects of anatomical change during head and neck (H&N) radiotherapy. The process of identifying patients for ART can be subjective and resource-intensive. This feasibility project aims to design and validate a pipeline to automate the process and use it to assess the current clinical pathway for H&N treatments.

The pipeline analysed patients’ on-set cone-beam CT (CBCT) scans to identify inter-fractional anatomical changes. CBCTs were converted into synthetic CTs, contours were automatically generated, and the original plan was recomputed. Each synthetic CT was evaluated against a set of dosimetric goals, with failed goals causing an ART recommendation.

To validate pipeline performance, a ‘gold standard’ was synthesised by recomputing patients’ original plans on a rescan-CT acquired during treatment and identifying failed clinical goals. The pipeline sensitivity and specificity compared to this ‘gold standard’ were calculated for 12 ART patients. The pipeline was then run on a cohort of 12 ART and 14 non-ART patients, and its sensitivity and specificity were instead calculated against the clinical decision made.

The pipeline showed good agreement with the synthesised ‘gold standard’ with an optimum sensitivity of 0·83 and specificity of 0·67. When run over a cohort containing both ART and non-ART patients and assessed against the subjective clinical decision made, the pipeline showed no predictive power (sensitivity: 0·58, specificity: 0·47).

Good agreement with the ‘gold standard’ gives confidence in pipeline performance and disagreement with clinical decisions implies implementation could help standardise the current clinical pathway.

To gather and analyse information from the literature concerning the management of otitis media with effusion in adults.

A review of the English-language literature from 1970 to the present.

Ventilation tubes have been the standard treatment for otitis media with effusion in adults, but examination of the results of published studies shows that they are associated with disappointing outcomes and significant complications, notably intermittent or chronic discharge, particularly in cases associated with nasopharyngeal carcinoma. Balloon dilatation of the Eustachian tube, intratympanic steroid therapy and cortical mastoidectomy appear to be possible alternatives.

A rethink of the management of otitis media with effusion in adults is needed, together with further research. For cases not associated with nasopharyngeal carcinoma, intratympanic steroid therapy appears to be a promising option.

Sarcomas occurring during pregnancy are rare and they present significant challenges in clinical management, to optimise, investigations and treatment choices to ensure both maternal and foetal well-being.

A 32-year-old G1P0 female presented with a rapidly growing swelling in her right axilla. Ultrasound-guided core needle biopsy revealed a high-grade pleomorphic malignant tumour. The dilemmas and choices weighing the risks of staging studies, risks of contrast-enhanced scans, surgery during pregnancy and pre- and post-operative radiotherapy to both the mother and foetus are discussed in this case report

Decision of unenhanced whole-body MRI was chosen for staging studies to mitigate radiation and contrast risks to the foetus and mother. Imaging studies revealed a 10 cm tumour in the right axilla, displacing the subclavian neurovascular structures but without evidence of metastatic disease. Concerns about pre-operative radiotherapy including proton beam radiotherapy, given risk of tumour progression and surgical challenges post-radiation therapy, a consensus decision was reached to proceed with surgical resection followed by delivery of the baby and post-operative radiotherapy. Successful limb-preserving sarcoma surgery was performed at 26 weeks of gestation. She gave birth to a healthy female child at 38 weeks of gestation, and she is receiving post-operative radiotherapy.

Sarcomas diagnosed during pregnancy are rare and delicate balance is required for optimising oncologic outcomes and minimising risks to the mother and the foetus. Decision-making involving multiple specialties and multidisciplinary teams, a treatment plan was formulated that prioritised the safety of the patient and her baby.

Radiotherapy with androgen deprivation therapy (ADT) is the standard of care for locally advanced prostate cancer but causes erectile dysfunction (ED). Vacuum erectile devices (VED)s are a first-line treatment for ED along with phosphodiesterase-5 inhibitors (PDE5-Is), yet all evidence supporting their use arises from post-surgical ED. This study aimed to assess effectiveness of VEDs for patients with ED resulting from radiotherapy and ADT.

This service evaluation utilised a longitudinal survey method to gather ED scores at baseline, after commencing ADT and after receiving a VED. Patients who were undergoing ADT for prostate cancer either before or alongside radical radiotherapy and who had been referred to receive a VED were invited to participate. Data including how patients used the VED, psychosexual counselling and PDE5-Is were also collected. Thematic analysis was used to identify men’s perceptions of the VEDs.

Data from the 15 participants demonstrated statistically significant treatment-related ED but failed to determine impact of VED on this. Qualitative data identified that participants found the VEDs to be unhelpful, too clinical, unappealing, emasculating and frustrating to use. Limited data suggested that VEDs are more effective at treating ED when used in combination with PDE5-Is.

Patients in this small sample generally reported dissatisfaction with VED usage. Limited engagement with the study frustrated attempts to draw conclusions regarding the effectiveness of VEDs for radiotherapy patients suffering from ED during ADT and a larger national study should be conducted to establish this. Improvements to the care pathway and access to psychosexual counselling are recommended.

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.

Valid and informed consent in healthcare is an ethical and legal requirement. This evaluation reports the practices within UK radiotherapy departments surrounding consent processes and therapeutic radiographer (TR) education. This article focuses on those patients who are considered to lack the capacity to consent.

This service evaluation adopted a qualitative research design. Seventy-six radiotherapy department managers were sent the online survey: containing a combination of open, closed and free text questions relating to consent practices. Descriptive analysis using Microsoft Excel was performed; additional correlation analysis was attempted with Fisher’s exact test using Statistical Package for the Social Sciences.

TRs from 39 radiotherapy departments (51%) completed the survey. Analysis of results demonstrated obtaining written consent before radiotherapy treatment was completed in all departments. Assessment methods used to determine capacity to consent varied across the departments. Responses identified 37 departments employ a different consent form for those considered to lack capacity. Thirty-eight departments have a policy surrounding consent; 16 departments reported no formal TR education in consent. Of the remaining 22 departments, 13 departments included lack of capacity within their education package.

To ensure best practice throughout the UK, is it recommended that radiotherapy departments review their consent processes to ensure they are in the best interests of the patient. It is recommended that TRs are familiar with their regulatory body standards and the ethical and legal issues surrounding consent; all departments should consider capacity and those considered to lack capacity within their education and training framework.

Second primary breast cancers are among the most common risks to female patients who have received radiotherapy for mediastinal lymphoma.

This study aims to audit breast dose in women who received mediastinal radiotherapy for lymphoma and compare the combined dose parameter values measured to those in the literature.

Twenty-three patient datasets from 2017 to 2021 were obtained. Inclusion criteria, such as female gender and 30Gy prescription dose, were applied. Target volumes were delineated using involved site radiotherapy and planned on Eclipse (Varian, Palo Alto, CA) using either fixed field or VMAT. Breast contours were retrospectively outlined according to RTOG/EORTC guidance and descriptive statistics were used to compare findings to those from the literature.

Differences were found in V4gy, V5Gy and mean dose compared to the literature with mean dose being 2Gy in the literature and 4Gy in this audit.

Breast dose parameter values between patients in this study vary due to multiple factors. These include the treatment delivery method used and the position of the treatment field in relation to the location of breast tissue. Mean dose and V4% and V5% to breast tissue found in this study differ from that found in the literature. This study highlights the importance of accurate contouring and optimising breast tissue when possible.

This project developed and validated an automated pipeline for prostate treatments to accurately determine which patients could benefit from adaptive radiotherapy (ART) using synthetic CTs (sCTs) generated from on-treatment cone-beam CT (CBCT) images.

The automated pipeline converted CBCTs to sCTs utilising deep-learning, for accurate dose recalculation. Deformable image registration mapped contours from the planning CT to the sCT, with the treatment plan recalculated. A pass/fail assessment used relevant clinical goals. A fail threshold indicated ART was required. All acquired CBCTs (230 sCTs) for 31 patients (6 who had ART) were assessed for pipeline accuracy and clinical viability, comparing clinical outcomes to pipeline outcomes.

The pipeline distinguished patients requiring ART; 74·4% of sCTs for ART patients were red (failure) results, compared to 6·4% of non-ART sCTs. The receiver operator characteristic area under curve was 0·98, demonstrating high performance. The automated pipeline was statistically significantly (p < 0·05) quicker than the current clinical assessment methods (182·5s and 556·4s, respectively), and deformed contour accuracy was acceptable, with 96·6% of deformed clinical target volumes (CTVs) clinically acceptable.

The automated pipeline identified patients who required ART with high accuracy while reducing time and resource requirements. This could reduce departmental workload and increase efficiency and personalisation of patient treatments. Further work aims to apply the pipeline to other treatment sites and investigate its potential for taking into account dose accumulation.

This study compares tumor control probability (TCP) and normal tissue complication probability (NTCP) across different hypo-fractionated (HypoRT) and conventional breast radiotherapy regimens using radiobiological models.

Computed tomography data from 30 patients with left breast-conserving surgery were used to evaluate three HypoRT regimens (39 Gy and 41·6 Gy in 13 fractions, and 40 Gy in 15 fractions) and a conventional regimen (50 Gy in 25 fractions). Dose-volume histograms (DVHs) were extracted for radiobiological calculations using Equivalent Uniform Dose (EUD) and Poisson models for TCP, and EUD and LKB (Lyman-Kutcher-Burman) models for NTCP.

Conventional treatment achieved significantly higher TCP (95%) than all HypoRT regimens (p < 0·001), with no significant differences between HypoRT regimens (p > 0·05. The 39 Gy/13 fraction regimen showed the lowest lung NTCP (p < 0·05). HypoRT regimens had significantly lower NTCP for the lungs and heart compared to the conventional regimen (p < 0·01). TCP and NTCP values from Poisson and LKB models were higher than those from the EUD model (p < 0·01).

HypoRT regimens reduced NTCP, with the lowest values in the regime of 39 Gy/13 fractions regimen, though the conventional regimen had higher TCP.

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.

Radiotherapy is a common treatment modality for cancer patients. Unfortunately, the treatment can result in skin reactions that may affect their quality of life and clinical outcomes. PILs can provide guidance on managing early symptoms and reduce unscheduled treatment breaks. Evaluating PILs is not frequently evidence-based, and research into evaluating PILs’ inclusiveness for radiotherapy skin reactions does not exist. This study aims to contribute to the knowledge base to better serve the whole radiotherapy population.

A constructivist methodology was developed to evaluate skin-tone inclusivity in the author’s local PILs, and a literature review was conducted to assess the knowledge base and facilitate providing recommendations for improvement.

Publication, diagnostic, language and educational bias were identified in the literature. The content analysis found the author’s departmental PILs were not inclusive of medium and dark-skinned patients.

Further research into radiotherapy PILs inclusivity is warranted. The creation or amendments to existing radiotherapy skin reaction diagnostic tools are needed to cater for the whole population. Diverse educational resources are needed to contribute to the reduction of health inequalities faced by radiotherapy patients.

Temporal bone osteoradionecrosis is a rare but significant complication of radiation for head and neck malignancies. Various management techniques have been described, but no clear protocol exists.

A retrospective case review of patients with temporal bone osteoradionecrosis managed over 15 years was carried out to highlight multidisciplinary team (MDT) management. The review findings were compared with the published literature and a protocol was derived for the management of future cases.

A total of 20 patients were included. The sites of osteoradionecrosis included the external auditory canal, the middle ear and the lateral skull base, presenting with features including recalcitrant pain, infection, neuropathies and intracranial sepsis. Treatments included hyperbaric oxygen, antibiotics, debridement and, in advanced cases, lateral temporal bone resection with vascularised tissue transfer. Post-operative and long-term outcomes were discussed.

Early temporal bone osteoradionecrosis may be managed conservatively. Refractory osteoradionecrosis can be life-threatening because of intracranial complications and sepsis. Such cases need an MDT approach with radical skull-base surgery for removal of necrotic foci and reconstruction using vascularised tissue transfer.

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.

In decision making regarding the management of vestibular schwannomas, alongside clinical outcomes, an understanding of patient reported health-related quality of life measures is key. Therefore, the aim of this research is to compare health-related quality of life in vestibular schwannoma patients treated with active observation, stereotactic radiotherapy and microsurgical excision.

A cross-sectional study of patients diagnosed with unilateral sporadic vestibular schwannomas between 1995 and 2015 at a specialist tertiary centre was conducted. Patients completed the Penn Acoustic Neuroma Quality of Life questionnaire and handicap inventories for dizziness, hearing and tinnitus.

Of 234 patients, 136 responded (58.1 per cent). Management modality was: 86 observation, 23 stereotactic radiotherapy and 25 microsurgery. Females reported significantly worse dizziness; males reported significantly worse physical disability. Patients less than 65 years old reported significantly worse tinnitus and pain scores. Overall, quality of life was higher in the observation group.

Conservative management, where appropriate, is favourable with higher quality-of-life outcomes in this cohort. This must be weighed against the risks of a growing tumour.

The main goal of radiation therapy is to eradicate all cancer cells and minimize the damage to healthy tissues around the tumour. Treatment planning systems are used to predict the outcome of the treatment in terms of dose distribution prior to the treatment. One of the most reliable dose calculation algorithms is Monte Carlo. The aim of this study is to evaluate the performance of automated external contouring tool on dose calculation using Monte Carlo algorithm.

The external contour of thorax phantom was created by automated tools of Monaco treatment planning system, and then, the IAEA-TECDOC-1583 quality assurance tests were created. Then, the treatment plans were delivered to the phantom, and the dose was measured by the Farmer ionization chamber at specific points. The external contour was corrected according to the source surface distances (SSD) which are mentioned in TECDOC-1583, and the dose was re-calculated. Finally, a comparison was made between the results.

Dosimetric tests of TECDOC-1583 showed the errors ranged from −2·8% to +2·5%. In case of editing external contour and omitting fluctuations, the errors were decreased. The comparisons indicated that the most significant variation occurred in test 4 and the least changes were related to the tests 1 and 3.

The results of the study showed that the fluctuations of the external contour affect the calculated volume of the phantom and thus the dose. In order to obtain correct results, automated external contouring tools should be used with the correct instructions and re-checked before treatment planning.

To determine oncological and functional outcomes in patients with T3 and T4 laryngeal carcinoma, in which choice of treatment was based on expected laryngeal function and not T classification.

Oncological outcomes (disease-specific survival and overall survival) as well as functional outcomes (larynx preservation and functional larynx preservation) were analysed.

In 130 T3 and 59 T4 patients, there was no difference in disease-specific survival or overall survival rates after radiotherapy (RT) (107 patients), chemoradiotherapy (36 patients) and total laryngectomy (46 patients). The five-year disease-specific survival rates were 83 per cent after RT, 78 per cent after chemoradiotherapy and 69 per cent after total laryngectomy, whereas overall survival rates were 62, 54 and 60 per cent, respectively. Five-year larynx preservation and functional larynx preservation rates were comparable for RT (79 and 66 per cent, respectively) and chemoradiotherapy (86 and 62 per cent, respectively).

There is no difference in oncological outcome after (chemo)radiotherapy or total laryngectomy in T3 and T4 laryngeal carcinoma patients whose choice of treatment was based on expected laryngeal function.
