CyberKnife Radiosurgery in India
CyberKnife® is the only FDA approved completely Robotic Stereotactic Radiosurgery System available in the world that targets and destroys small and previously inaccessible tumors or lesions anywhere the body.
As a non-invasive “operation”, CyberKnife has proven to be an effective alternative to surgery or conventional radiation for treating vascular abnormalities, tumors, functional disorders, and cancers with sub-millimeter accuracy. CyberKnife gives renewed hope and the possibility of a better quality of life, especially for patients with tumors previously diagnosed as inoperable, and for those who have already received the maximum amount of radiation through other treatment methods.
CyberKnife uses advanced robotics and computer guidance to deliver precise radiation beams to treat tumors anywhere in the body…even those previously thought untreatable with other radiosurgery systems. A computer program evaluates the unique shape and location of the tumor to determine the orientation of each of the 1,200 or more beams of radiation that will target the tumor. Each tumor generally requires one to five treatments, each lasting 45 to 90 minutes.
Common Conditions Treatable By CyberKnife Radiosurgery
- Astrocytoma, Glioma, Glioblastoma Multiforme, Oligodendroglioma : - CyberKnife offers superior conformance to tumour shape, which is important especially for recurrence after surgery and conventional radiotherapy. CyberKnife can also irradiate the tumour bed to delay or prevent recurrence.
- Brain metastases : - Radiosurgery may be equal to surgery for single metastases and better for multiple metastases. Advanced imaging allows CyberKnife® to treat those that are widely dispersed.
- Spinal Tumours : - CyberKnife® is regularly used to treat spinal metastases. It may also serve as a treatment for many primary spinal tumours.
- Pituitary Adenoma : - CyberKnife's® staged treatments may help to avoid or minimize the risk of visual loss and other side effects associated with single-session radiosurgery. Its superior conformance minimizes irradiation of normal tissue, including the optic chiasm and hypothalamus.
- Hemangioblastoma : - CyberKnife® non-invasively treats the tumour nodule, usually in one session, even in hard-to-reach areas. This is especially beneficial for Von Hippel Lindau disease patients who can become disabled by multiple surgeries.
- Skull Base Tumours : - The proximity of these tumours to vital nerve and vascular structures makes them surgically problematic.
- Meningioma :- For smaller meningiomas, radiosurgery is an ideally non-invasive therapy. CyberKnife® is especially safe for meningiomas adjacent to critical structures because it can be delivered in fractions.
- Neurofibroma & Schwannoma : - While these tumours' resistance to radiation makes conventional radiotherapy an option only when surgery is not, CyberKnife's® conformance makes it an effective alternative to radiation therapy and surgery for selected patients.
- Acoustic Neuroma : - Studies show that CyberKnife® treatment in stages offers the highest rates ever achieved for hearing and facial-nerve preservation besides effective control of the tumour-growth.
- Intracranial AVMs : - With CyberKnife®, we can treat locations that can't be safely approached with microsurgery or endovascular therapy. Selected AVMs have an 80% chance of disappearing after a single treatment session though it may take some time. CyberKnife® can also be used in conjunction with other therapies to remove remnants.
- Spinal AVMs : - CyberKnife® is the first and the only system to offer radiosurgical treatment of spinal AVMs .It provides the same or even more accuracy and success as for intracranial AVMs
