Background: Most newly diagnosed oropharyngeal and hypopharyngeal cancers are treated with chemoradiotherapy with curative intent but at the consequence of adverse effects on quality of life. We aimed to investigate if dysphagia-optimised intensity-modulated radiotherapy (DO-IMRT) reduced radiation dose to the dysphagia and aspiration related structures and improved swallowing function compared with standard IMRT.
Methods: DARS was a parallel-group, phase 3, multicentre, randomised, controlled trial done in 22 radiotherapy centres in Ireland and the UK.
•There is a lack of prospective level I evidence for the use of PBT for most adult cancers including oropharyngeal squamous cell carcinoma (OPSCC).•TORPEdO is the UK's first PBT clinical trial and aims to determine the benefits of PBT for OPSCC.•Training and support has been provided before and during the trial to reduce variations of contouring and radiotherapy planning.

Methods: We performed a phase III open-label randomised controlled trial in patients with laryngeal or hypopharyngeal cancer (AJCC III-IVa/b, TNM 7).
Importance: Malignant spinal canal compression, a major complication of metastatic cancer, is managed with radiotherapy to maintain mobility and relieve pain, although there is no standard radiotherapy regimen.
Objective: To evaluate whether single-fraction radiotherapy is noninferior to 5 fractions of radiotherapy.
Design, Setting, And Participants: Multicenter noninferiority randomized clinical trial conducted in 42 UK and 5 Australian radiotherapy centers.
Purpose Of The Study: To describe the clinical and histopathological features of an aggressive ciliary body adenocarcinoma with pulmonary metastases and skull base spread.
Procedures And Results: A 45-year-old female patient presented with a post-traumatic phthisical eye that was eviscerated. This showed an unexpected carcinoma (positive for cytokeratins and melanocytic markers), the histological differential diagnosis for which included a primary ciliary body adenocarcinoma or a metastasis.
Background: The incidence of human papillomavirus (HPV)-positive oropharyngeal cancer, a disease affecting younger patients, is rapidly increasing. Cetuximab, an epidermal growth factor receptor inhibitor, has been proposed for treatment de-escalation in this setting to reduce the toxicity of standard cisplatin treatment, but no randomised evidence exists for the efficacy of this strategy.
Methods: We did an open-label randomised controlled phase 3 trial at 32 head and neck treatment centres in Ireland, the Netherlands, and the UK, in patients aged 18 years or older with HPV-positive low-risk oropharyngeal cancer (non-smokers or lifetime smokers with a smoking history of <10 pack-years).
Human papillomavirus (HPV) infection is causally related to a subset of oropharyngeal carcinomas (OPC) and is linked to a more favourable prognosis compared to HPV-negative OPC. The mechanisms underlying this effect on prognosis are not fully understood, but interactions with the tumour microenvironment may be pivotal. Here, we investigated the role of the tumour microenvironment in HPV-positive compared to HPV-negative cancer using 2D and 3D modelling of OPC interactions with stromal fibroblasts.

Patients with spinal cord compression have complex physical, psychological and social care needs. This article describes a multidisciplinary project aimed at improving the care provided to newly diagnosed patients who were admitted to a regional cancer centre for radiotherapy.

If not detected early, MSCC can result in paralysis and significant bowel and bladder dysfunction that is not improved by treatment. Patients have to cope with sudden and unexpected disability alongside a diagnosis of advanced cancer.

Nine patients with non-small cell lung cancer (NSCLC) gave written informed consent to undergo a free-breathing CT, an inspiration breath-hold CT and a 3D ventilation (3)He-MRI in CT position using an elliptical birdcage radiofrequency (RF) body coil. (3)He-MRI to CT image fusion was performed using a rigid registration algorithm which was assessed by two observers using anatomical landmarks and a percentage volume overlap coefficient.
