CyberKnife® revolutionary radiosurgery – what can and cannot be treated
Posted Jan 11 2012 3:42am
CyberKnife®, a robotic radiosurgery treatment, was developed in the 1990’s and has since been used to treat over 100,000 patients. The ‘surgery’ is in fact an alternative form of radiotherapyThe treatment of disease using radiation. involving hundreds of pencil thin beams of radiationEnergy in the form of waves or particles, including radio waves, X-rays and gamma rays. which are moved around the body by a robotic arm allowing for highly precise targeting of tumours.
The following conditions are suitable for treatment with the CyberKnife® radiosurgery technique:
Low grade Astrocytomas (grade 2/3)
Brain metastasesSecondary tumours’ that result from the spread of a malignant tumour to other parts of the body. (usually one – three)
Spinal metastasisThe spread of a malignant tumour to other parts of the body. (usually solitary)
Lymph node metastases
Recurrent Head and Neck Cancer
Due to its high concentration of radiation CyberKnife® cannot be used to treat all tumours or cancers, particularly those that are larger or have spread to multiple sites. The following are unable to be treated with CyberKnife®:
Multiple brain metastases (usually greater than three)
Tumours (more than 8cm in diameter)
Lung Cancer stages 2/3
