| Abstract | ESTRO 35 2016 _____________________________________________________________________________________________________ treatment delivery, optimal clinical outcome and meaningful reporting and comparison of treatments. In addition to high quality imaging and contouring guidelines, solid knowledge of radiological anatomy is a precondition to achieve best contouring standards. While this subject is recognized as one of the key competencies in the radiation oncology core curricula and training programmes [Eriksen JG, et al. Radiother Oncol 2012, www.acgme-i.org,], there is limited published data regarding the actual impact of the teaching interventions on contouring skills and the characteristics of the learning curve [Jaswal JK, et al. IJROBP 2014, Cabrera AR, et al. J Am Coll Radiol 2011, Bekelman JE, et al. IJROBP 2009, D’Souza L, et al. BMC 2014]. Furthermore, published national surveys among radiation oncology residents and residency program directors indicate that there is room for improvement of training and evaluation of contouring competencies during residency [Jani AB, et al. Pract Rad Onc 2015, 12Jaswal JK, et al. IJROBP 2013]. Contouring training should not be viewed as a process limited to the residency and fellowship programs and corecurriculums. In a study evaluating the impact of prospective contouring rounds in a high volume academic centre, 36 % of cases required modification of contouring or written directives prior to treatment planning [Cox BW, et al. Pract Rad Onc 2015]. In a study of stereotactic body radiotherapy for lung cancer, the institutional peer-reviewers recommended major and minor changes of delineations in 23 % and 37 % of 472 contoured structures, respectively [Lo AC, et al. J Thor Onc 2014]. In view of the rapid developments of imaging and radiotherapy delivery, accompanied by constant evolution and development of new contouring recommendations, the importance of continuous education of the experienced practitioners, mentors and trainers cannot be overemphasized. Research focusing on site-specific volumetric, topographic and qualitative aspects of contouring variation informs the educational activities in this field. The growing number of published inter-observer studies offers valuable resource to guide the training process. Limiting the learning to didactic and case-based instructions has improved knowledge scores and resident satisfaction in one study. However, this was not translated into improved contouring accuracy [D’Souza L, et al. BMC 2014]. In our experience, site-specific curriculum based on intensive sequence of didactic presentations, system-based instructions and hands-on contouring workshops represents an optimal strategy to achieve good learning results [Segedin B, et al. Submitted to Radiol Oncol 2016]. Feasibility and effectiveness of similar intensive educational interventions has been confirmed by others [Jaswal J, et al. IJROBP 2014]. These favourable early outcomes of teaching cannot be extrapolated on the long-term scale.Further evidence-based characterization of the learning curve is required to quantify the needs for continuous education and identify strategies for long term knowledge consolidation. Relative impact of the individual educational modules and qualifications of trainers on the learning outcome needs to be quantified, taking the tumour-site specific challenges into account. Development of training tools, including e-learning platforms and tools for objective assessment of contouring represent some of the main pre-requisites for future improvements in this field. |
