Dr. Frank Lagerwaard, University Medical Centre, Amsterdam, Netherlands, discusses the use of stereotactic radiosurgery to treat lesions within the lungs. Novel linear accelerators use CT scans to image the tumour on the accelerator while treating the tumour with an extremely accurately delivered high dose of radiation. The accuracy of this non-invasive treatment minimises damage to the surrounding healthy tissues and consequently the therapy has a very low toxicity profile. Dr. Lagerwaard explains how suitable patients are selected, describes what benefits are seen in terms of local control and survival rates and explains how it compares to other treatment options such as surgery and radio frequency ablation.
