Abstract
Chordomas can present a challenge to the radiation oncologist and surgeon owing to the proximity to neurological structures. We describe a case of long-term tumour control in a chordoma of the lumbar spine following high-dose palliative radiotherapy. Image-guided intensity-modulated radiotherapy with photons provided a good solution to deliver 65 Gy to the tumour in a technically challenging case, and local control has been sustained over a period of years.
