Which factors would affect my case?
Each CyberKnife centre may adopt slightly different criteria, but the following points are likely to be key.
Number of tumours
A separate treatment plan with a large number of radiation pulses plus tracking in between has to be set up for each tumour. Most centres therefore restrict treatment to a small number of tumours.
Size of tumour
Metastasis from breast cancer, before and 4 weeks after CyberKnife treatment.
It takes longer to treat a large tumour and the radiation exposure to adjacent healthy tissue increases, so centres impose a maximum size.
CyberKnife can avoid open surgery in some cases, but the treated matter is not removed. The body can reabsorb small amounts of dead matter but larger tumours may pose problems.
Type of tumour
We give some guidance on the CyberKnife Treatments page but do not assume that if you do not see your type on the list that it cannot be treated.
More information is available from the manufacturer's web site for patients cyberknife.com, where you will find their latest guidance notes.
Characteristics of tumour
CyberKnife is best suited to tumours which are well delineated from the surrounding healthy tissue. It is not so well suited to diffuse tumours such as gliomas.
Location of tumour
Difficult locations and complex shapes which would bar open surgery may still be open to CyberKnife, so this should definitely not deter your enquiry.
My tumour is too large for CyberKnife but my surgeon says it is too dangerous to operate.
It may be possible to reduce the tumour mass first, by surgery or chemotherapy and then treat the remaining tumour with CyberKnife.
I have already had the maximum radiotherapy
Because of the high accuracy of CyberKnife it can sometimes be used even when you have already had the maximum conventional radiotherapy treatment.
Enquiry for CyberKnife radiosurgery
We work with English-speaking CyberKnife centres in Europe, including pioneering centres which offer training and technical support to new CyberKnife centres.
Learn how patients are assessed for CyberKnife radiosurgery and apply for yourself or another person.
Enquire now without cost or commitment and we will tell you what we can suggest in your case.
We can also have your case reviewed at no extra cost for other treatments at university hospitals or for proton or ion beam therapy. On request we can also introduce patients to CyberKnife centres or hospitals outside our regular service.
Assessment for treatment
Why can't I get palliative treatment?
This can be a difficult situation. In fact CyberKnife can be quite well suited to palliative treatments to relieve pain and improve quality of life, yet many centres are reluctant to offer them.
They will not tell you this, but one reason can be that the treatment will not be counted as a 'success' in their record, and so damage their standing.
The good news is that we can usually help in such cases. If CyberKnife can assist in your situation, then we can introduce you to centres which will offer these important treatments.
Not just CyberKnife
