Enhancing Specialist Training in Radiation Oncology through the Implementation of Structured Radiotherapy Contouring Workshops

PURPOSE/OBJECTIVE(S)

Contouring tumor volumes and organs at risk is a key component of Radiation Oncology specialist training. As trainees rotate through different tumor sites, they are expected to develop proficiency in contouring skills relevant to their year of training. These skills have historically been acquired in an unstructured manner during supervised clinical work. However, trainees often struggle to learn these skills due to variability in practice and approach amongst senior colleagues. Research has shown that contouring workshops improve the standardization of contouring and can be an effective way of enhancing the learning experience through interaction, instant feedback and reflection. We present our experience of implementing structured contouring workshops and the feedback received from the trainees.

MATERIALS/METHODS

Eight contouring workshops were held in our institution over a period of 3 years between 2019 and 2022. These included Head & Neck (3), Prostate (1), SABR Lung (2), Breast (1), and Esophagus (1). Six were held in-person pre-COVID and two in a virtual format during the pandemic. Each workshop was 2 hours long and attended by trainees with varying levels of contouring experience. All the workshops were facilitated by a consultant radiation oncologist and a clinical tutor and followed a similar format consisting of a brief tutorial on the tumor site, followed by a contouring demonstration on an anonymized case on an Eclipse planning platform referencing published contouring atlases. Each of the trainees had access to a copy of the same case throughout the workshop and their contours were then reviewed both individually and collectively. A key component of the workshops was instant feedback, as trainees could compare their contours to that of the tutors and discuss any differences. Feedback on the contouring workshop was then collected through a post workshop questionnaire.

RESULTS

The workshops were attended by an average of 12 trainees (range 10 to 14). Regardless of their year of training, all trainees rated the content and format of the workshops highly and stated they were relevant to their daily practice. Their subjective level of confidence in contouring in that specific tumor site improved significantly, going from an average of 5.6 out of 10 (range of 4 to 7) before the workshop to 8.7 (range of 8 to 9) after the 8 workshops. All the workshops were conducted at no extra cost as they were held using our existing planning software.

CONCLUSION

The trainees indicated that the workshops were of definite educational benefit and strongly supported incorporating this approach to teaching contouring skills into the curriculum. Based on this feedback, these contouring workshops have been integrated into the recently revised higher specialist training curriculum on a more structured basis. This will ensure that trainees will continue to develop progressive expertise in contouring skills in keeping with best international practice as they advance through their training scheme.
