This Falcon Workshop will explore the challenges and suggest areas of evidence based best practice in lung cancer re-irradiation. Participants will be asked to delineate a lung cancer recurrence case prior to week 1 which we will use as the basis of our discussions. The primary aim of the course will be to reduce clinical variability and inconsistency for this complex yet increasingly prevalent clinical scenario.
In week 1 a brief overview will be given on patient selection for lung re-irradiation. A radiologist will also give suggestions on how to differentiate radiotherapy related field changes from recurrent malignancy . We will explore target (GTVp, GTVn, ITV, PTV) and organ at risk contouring (proximal bronchial tree, heart, oesophagus, brachial plexus). The participants' delineations (both target and organs at risk) will be compared to the teachers’ delineations while discussing the differences. Participants will also be given a second opportunity to adjust their contours prior to the week 2 session.
In week 2 we will discuss evidence based cumulative dose constraint and the physicists team will address the challenges relating to summation of organ at risk doses across plans using simple and advanced methodology to ensure relevance to different practice settings. We will apply the discussed cumulate dose constraints to our case from week 1 and review participants contours and the subsequent cumulative dose plan.
This will be a multi-disciplinary workshop that will offer an opportunity to meet with radiation oncology, clinical physics and radiology colleagues interested in the field of lung cancer re-irradiation, and discuss the challenges and pitfalls to consider in everyday practice.
