The CyberKnife  Treatment Process


Qualification for CyberKnife treatment

All patients referred to Warsaw - Wieliszew Cyberknife Center - are examined and discussed by a multidisciplinary medical team. Each case is evaluated individually as to the appropriateness of CyberKnife treatment.


After the acceptation, patient undergoes imaging procedures to determine the size, shape and location of the tumor. A standard high-resolution CT scan is performed, and certain tumors may also need other imaging techniques, such as MRI, angiography or PET.


Following the scanning, the image data is digitally transferred to the CyberKnife System's treatment planning workstation, where the treating radiation oncologist in cooperation with experienced surgeon (specialist in either: neurosurgery, thoracic surgery, gastrointestinal surgery or urology respectively) identifies the exact size, shape and location of the tumor to be targeted and the surrounding vital structures to be avoided. An imaging diagnostics’ specialist is also a member of the team. A qualified medical physicist then uses the CyberKnife software to generate a treatment plan to provide the desired radiation dose to the identified tumor location while avoiding damage to the surrounding healthy tissue. As part of the treatment plan, the CyberKnife System’s proprietary planning software automatically determines the number, duration and angles of delivery of the radiation beams.


During a CyberKnife procedure, a patient lies comfortably on the treatment table, which automatically positions the patient. Then the CyberKnife System’s computer-controlled robot slowly moves around the patient to the various locations from which it will deliver radiation to the tumor. Anesthesia is not required, as the procedure is painless and non-invasive. The treatment, which generally lasts 30 - 90 minutes, typically involves the administration of 100 - 200 radiation beams delivered from different directions, each lasting from 10 to 15 seconds. The patient may leave the facility immediately upon completion of the procedure.


After 3-6 months following the treatment, CT or/and MRI  are performed to confirm the destruction and eventual elimination of the treated tumor.

If treatment is being delivered in stages, patients will need to return for additional treatments over several days (typically no more than 5), as determined by the treating radiation oncologist. Patients may experience some minimal side effects, but those often go away within the first week or two after treatment
