received from centres routinely inserting fiducial markers for prostate IGRT. Across these fifteen UK centres eleven professional groups insert fiducial markers, Urology Consultants most commonly. Fourteen centres inserted fiducial markers trans-rectally; one trans-perineal insertion. Twelve centres administered anaesthetic prior to fiducial marker insertion. The 14 centres using a transrectal approach administered prophylactic ciprofloxacin as a single agent or in combination with gentamicin or metronidazole. There was poor agreement between regimes presented. Only one centre screened for ciprofloxacin resistant organisms. Nine centres continued patients on low dose aspirin. Five brands of fiducial markers are utilised across the UK. Single markers, 3 mm long with a diameter or 1.0-1.2 mm are most popular. Fourteen centres standardly inserted three single fiducial markers into the prostate, two common configurations emerged. One centre inserted two coupled fiducial markers, two other centres utilise coupled markers for CyberKnife (Accuray Inc., Sunnyvale, CA) patients only. All centres delayed at least 1 week between fiducial insertion and planning CT, with seven centres waiting two weeks. The most common fiducial verification methods is two dimensional, paired kilo Voltage (kV) images. Conclusion There is considerable variation in fiducial marker practice across the UK. Based on current UK practice and supporting literature, seven recommendations for fiducial marker best practice have been outlined (Table 1) . Implementation of these in to UK departments would assist standardisation of national practice. They also prove to support naïve centres and healthcare professionals developing this service.

Conclusion The existing literature on this topic tends to look at qualified staff with little acknowledgment of the possibility that trainees may also experience this aspect of work. These results show that there it is not only an issue for qualified staff and that students, particularly female students are also at risk of compassion fatigue and mechanisms should be put in place to prevent compassion fatigue in this group. EP-2399 Benchmarking UK practice for fiducial marker insertion prior to prostate radiotherapy S. Alexander 1 , J. Kinsella 2 , H. McNair 3 , A.C. Tree 4 1 The Royal Marsden NHS Foundation Trust, Radiotherapy, Sutton, United Kingdom 2 The Royal Marsden NHS Foundation Trust, Uro-oncology, Chelsea, United Kingdom 3 The Royal Marsden NHS Foundation Trust and Institute of Cancer Research, Radiotherapy, Sutton, United Kingdom 4 The Royal Marsden NHS Foundation Trust and Institute of Cancer Research, Uro-oncology, Sutton, United Kingdom Purpose or Objective In the UK fiducial marker IGRT is the second most common verification method employed in radical prostate radiotherapy 1 yet there is little evidence to support centres introducing or developing this practice. We developed a survey to elicit current fiducial marker practices adopted in the UK to recommend standardisation of practice through agreement. Material and Methods A 16 question survey was developed to gather information regarding the insertion of fiducial markers including; patient preparation, imaging during treatment and multi- professional workforce development in the UK. A combination of yes/no, multiple-choice and open-ended questions were used. The survey was made available electronically through SurveyMonkey.net in addition to a paper copy. The survey was publicised at the British Uro-Oncology Group (BUG) Conference, 2016. Radiotherapy Service Managers were also informed of the survey via e-mail and asked to forward the survey link to the appropriate individual within their centre. The survey was open to responses from September 2016 to January 2017. Participation in the survey was voluntary without remuneration. Results Twenty surveys were returned; four responses were from centres not utilising prostate fiducial markers, one response was duplication, fifteen responses were

EP-2400 Implementing physical activity health advice among cancer patients in the radiotherapy department. P. Nickola 1 1 The London Clinic, Radiotherapy, London, United Kingdom Purpose or Objective Being physically active (PA) has many benefits for cancer patients, by improving overall outcomes and survival rates. However, in the UK only 23% of cancer patients are active to the national recommendations and 31% are completely inactive. It is a requirement that all health professionals advise cancer survivors to be PA to help improve patient outcomes. However few oncology health professionals do this. Patient education is an essential component of radiotherapy practice with Therapeutic Radiographers providing care to patients often over a
