Purpose: Radiotherapy (RT) for oropharyngeal cancer (OPC) can lead to late toxicity. Fatigue is a known debilitating issue for many cancer survivors, yet prevalence and severity of long-term fatigue in patients treated for OPC is unknown.

Method: As part of a mixed-methods study, fatigue in OPC patients ≥ 2 years post RT + / - chemotherapy was evaluated.

Aim: The Royal College of Radiologists (RCR) recognizes the importance of addressing differential attainment, bridging existing disparities, and fostering diversity and equity.

Materials And Methods: A joint-faculty reverse mentoring (RM) pilot launched from July 2023 to January 2024. Participation was voluntary, mentors (trainees) from ethnic minority backgrounds and mentees (RCR officers) were recruited across the UK.

Aims: Differential attainment (DA) in post graduate medical training is a recognised challenge and refers to unexplained variation across groups when split by several protected characteristics. The Royal College of Radiology is committed to fostering diversity, inclusivity, and equality with the goal of narrowing existing gaps and improving training outcomes.

Materials And Methods: This was a mixed methods study aiming to understand the causes of DA with view to helping the RCR develop strategies to address this.

Background: Late effects of cancer treatment, such as neurocognitive deficits and fatigue, can be debilitating. Other than head and neck-specific functional deficits such as impairments in swallowing and speech, little is known about survivorship after oropharyngeal cancer. This study examines the lived experience of fatigue and neurocognitive deficits in survivors of oropharyngeal squamous cell cancer and impact on their daily lives.

When radiotherapy is used in the treatment of head and neck cancers, the brain commonly receives incidental doses of radiotherapy with potential for neurocognitive changes and subsequent impact on quality of life. This has not been widely investigated to date. A systematic search of MEDLINE, EMBASE, Psycinfo Info and the Cochrane Central Register of Controlled Trials (CENTRAL) electronic databases was conducted.

Background: Data on the accuracy of response assessment 2-[fluorine-18]-fluoro-2-deoxy-D-glucose (FDG) positron emission tomography-computed tomography (PET-CT) following (chemo)radiotherapy in patients with oropharynx squamous cell carcinoma (OPSCC) is predominantly based on HPV-positive disease. There is a paucity of data for HPV-negative disease, which has a less favourable prognosis. Methods: 96 patients treated with (chemo)radiotherapy for HPV-negative OPSCC with baseline and response assessment FDG PET-CT between 2013−2020, were analysed.

Article Synopsis
  • There is growing interest in hypofractionated radiotherapy for head and neck cancer, but not enough data to establish a consensus on its use.
  • This multicenter study examined outcomes in oropharyngeal squamous cell carcinoma patients treated with either standard or accelerated mildly hypofractionated radiotherapy without chemotherapy.
  • Results showed no significant differences in locoregional control, overall survival, or swallowing function between the two treatment schedules, suggesting hypofractionated radiotherapy is a viable option for patients who cannot receive chemotherapy.

Article Synopsis
  • The study aimed to determine if the pretreatment absolute lymphocyte count (ALC) can help identify oropharyngeal squamous cell carcinoma (OPSCC) patients who might benefit from reducing chemotherapy during treatment.
  • Researchers analyzed data from nearly 800 patients undergoing treatment, assessing overall survival (OS) and locoregional control (LRC) based on ALC levels.
  • Findings suggested that ALC is a significant predictor of OS and indicates how well patients might respond to adding cisplatin chemotherapy, potentially guiding future treatment de-escalation strategies.

Introduction: Sinonasal malignancy is a rare and heterogenous disease, with limited evidence to guide management. This report summarises the findings of a UK survey and expert workshop discussion which took place to inform design of a proposed UK trial to assess proton beam therapy versus intensity-modulated radiation therapy.

Method: A multidisciplinary working group constructed an online survey to assess current approaches within the UK to surgical and non-surgical practice.

Aims: To analyse outcomes and patterns of failure in patients with oropharyngeal carcinoma (OPC) treated with definitive volumetric modulated arc therapy with omission of contralateral high level II lymph nodes (HLII) and retropharyngeal lymph nodes (RPLN) in the contralateral uninvolved neck.

Materials And Methods: Patients with OPC treated between January 2016 and July 2019 were retrospectively identified. In the absence of contralateral neck disease, institutional protocols allowed omission of contralateral HLII and contralateral RPLN in the additional absence of ipsilateral RPLN, soft palate/posterior pharyngeal wall primary.

Histiocytic sarcoma (HS) is an exceedingly rare and aggressive neoplasm of lymphoid and haematopoietic tissues and expresses histological and phenotypical characteristics of mature histiocytes. There have only been a few cases of documented HS in the head and neck region. Whilst patients with HS often have nodal or disseminated disease, patients can present with localised disease.

The influence of retropharyngeal lymph node (RPLN) involvement on prognosis in oropharyngeal carcinoma remains poorly defined. The aim of this study was to assess the impact of RPLN involvement upon outcomes. A single-centre retrospective analysis of 402 patients with oropharyngeal carcinoma treated nonsurgically between 2010 and 2017 was performed.

Aims: To evaluate patterns of locoregional recurrence following adjuvant (chemo)radiotherapy for oral cavity squamous cell carcinomas.

Materials And Methods: One hundred and one patients who received adjuvant radiotherapy ± chemotherapy for oral cavity squamous cell carcinoma between 2013 and 2016 were analysed. For documented locoregional recurrence, recurrence imaging was deformably co-registered to the planning computed tomography scan.

Introduction: The aim was to evaluate in oropharyngeal carcinoma the: (1) incidence and predictors of retropharyngeal (RP) lymph node (LN) involvement, (2) pattern of ipsilateral/bilateral/contralateral-only RP LNs (3) location of RP LNs in relation to contouring guidelines.

Methods: Single centre retrospective analysis of 402 patients with oropharyngeal carcinoma treated non-surgically between 2010 and 2017. All patients had a baseline FDG PET-CT and contrast-enhanced MRI and/or CT.
