OBJECTIVES: Contouring similarity metrics are often used in studies of inter-observer variation and automatic segmentation but do not provide an assessment of clinical impact. This study focused on post-prostatectomy radiotherapy and aimed to 1) identify if there is a relationship between variations in commonly used contouring similarity metrics and resulting dosimetry and 2) identify the variation in clinical target volume (CTV) contouring that significantly impacts dosimetry. APPROACH: The study retrospectively analysed CT scans of 10 patients from the TROG 08...
