Stereotactic radiosurgery
With its high level of precision, stereotactic radiosurgery can target tumours and deliver radiation doses with millimetre precision, therefore protecting the healthy organs and significantly reducing treatment times for the patient. In carefully selected patients, stereotactic radiosurgery can treat tumours growing in the brain, using intracranial stereotactic radiosurgery, as well as cancers diagnosed in other parts of the body, using extracranial stereotactic radiosurgery. In both cases, the aim of radiotherapy is to increase the localised radiation dose without increasing the dose to the surrounding healthy organs.

• Intracranial stereotactic radiosurgery
Fractionated intracranial stereotactic radiosurgery precisely targets the tumour to within a millimetre. Intracranial stereotactic radiosurgery is mainly used to treat small, malignant and benign primary brain tumours as well as brain metastases.

• Extracranial stereotactic radiosurgery
Fractionated extracranial stereotactic radiosurgery is based on the same concept and is used in numerous tumours, for example some lung and liver lesions where surgery is not, or is no longer, a feasible option. Stereotactic radiosurgery can also be used in combination with chemotherapy or when all lines of chemotherapy have failed.

Deep inspiration breath hold technique
This technique requires the patient to wear a pair of video-assisted goggles and use a spirometry to copy the visual display in the goggles and hold their breath for a few seconds. This technique is available in several centres and meets the objective of radiotherapy although this type of breathing affects the lung volume of patients during treatment. For patients who are receiving radiotherapy for breast cancer, the deep inspiration breath hold technique helps to prevent radiation-sensitive organs, such as the heart and superficial lung tissue, from being exposed to radiation beams and therefore reduce any delayed side effects, such as pulmonary fibrosis or heart failure, on these two organs.

Intraoperative radiotherapy
Intraoperative radiotherapy for breast cancer involves a single session of radiation delivered during the operation to surgically remove the tumour in the breast (lumpectomy). This technique, known as IORT, is an innovative treatment approach. However, its usage must be carefully standardised depending on the risk factors presented by the patient at the time of diagnosis. Centre d'Oncologie des Eaux-Vives can provide patients with access to this innovative technique, as IORT is a treatment option offered by Centre du Sein GSMN at Clinique Générale-Beaulieu and Clinique de Genolier, Swiss Medical Network members
