Updated Review of the Literature with a Focus on Tumour Subsite and Treatment Modality | Clinical Oncology
Technological advances in radiation therapy permit steep dose gradients from the target to spare normal tissue, but increase the risk of geographic miss. Suboptimal target delineation adversely affects clinical outcomes. Prospective peer review is a method for quality assurance of oncologists’ radiotherapy plans. Published surveys suggest it is widely implemented. However, it may not be feasible to review every case before commencement of radiation therapy in all departments. The rate of plan changes following peer review of cases without a specific subsite or modality is typically around 10%. Stereotactic body radiation therapy, head and neck, gynaecological, gastrointestinal, haematological and lung cases are associated with higher rates of change of around 25%. These cases could thus be prioritised for peer review. Other factors may limit peer review efficacy including organisational culture, time constraints and the physical environment in which sessions are held. Recommendations for peer review endorsed by the American Society for Radiation Oncology were made available in 2013, but a number of relevant studies have been published since. Here we review and update the literature, and provide an updated suggestion for the implementation of peer review to serve as an adjunct to published guidelines. This may help practitioners evaluate their current processes and maximise the utility and effectiveness of peer review sessions.
Children with cancer could be spared dozens of doses of general anaesthesia by projecting a video directly on to the inside of a radiotherapy machine during treatment | OnMedica
The new research was presented this week at the ESTRO 36 conference (European Society for Radiotherapy & Oncology), taking place in Vienna, Austria.
Catia Aguas, a radiation therapist and dosimetrist at the Cliniques Universitaires Saint Luc, Brussels, Belgium, told the conference that using video instead of general anaesthesia is less traumatic for children and their families, as well as making each treatment quicker and more cost effective.
The study included 12 children aged between one and a half and six years old who were treated with radiotherapy using a Tomotherapy® treatment unit at the university hospital. Six were treated before a video projector was installed in 2014 and six were treated after.
Before the video was available, general anaesthesia was needed for 83% of children’s treatments. Once the projector was installed, anaesthesia was only needed in 33% of treatments.

People with head and neck cancer (HNC) experience elevated symptom toxicity and co-morbidity as a result of treatment, which is associated with poorer psychosocial and quality-of-life (QoL) outcomes.
This Phase I study examined whether an individualised mindfulness-based stress reduction (IMBSR) programme could be successfully used with HNC patients undergoing curative treatment.
After controlling for pre-intervention mindfulness, there was an association between higher post-intervention mindfulness and lower psychological distress and higher total, social and emotional QoL. This study offers important preliminary evidence than an IMBSR intervention can be administered to HNC patients during active cancer treatment. A randomised controlled trial is warranted to confirm these findings.

Background: There still is no evidence which neoadjuvant therapy regimen for stage II–III rectal cancer is superior. The aim of this study was to compare results achieved after long-course chemoradiotherapy (CRT) with short-term radiotherapy (RT) followed by delayed surgery.
Conclusion: Three-years disease-free survival was better in CRT group comparing with RT group with no difference in overall survival.
