Cancer / Oncology Treatments

CyberKnife Robotic Radiosurgery

The CyberKnife Robotic Radiosurgery System is a non-invasive alternative to surgery for the treatment of both cancerous and non-cancerous tumors anywhere in the body, including the prostate, lung, brain, spine, liver, pancreas and kidney. The treatment – which delivers beams of high dose radiation to tumors with extreme accuracy – offers new hope to patients worldwide.

Though its name may conjure images of scalpels and surgery, the CyberKnife treatment involves no cutting. In fact, the CyberKnife System is the world’s first and only robotic radiosurgery system designed to treat tumors throughout the body non-invasively. It provides a pain-free, non-surgical option for patients who have inoperable or surgically complex tumors, or who may be looking for an alternative to surgery.

What is the Treatment Process?

CyberKnife® treatments involve a team approach in which several specialists participate. Prior to the procedure, the patient is imaged using a high-resolution CT scan, to determine the size, shape and location of the tumor. 

Following scanning, the image data is digitally transferred to the CyberKnife System’s workstation, where the treatment planning begins.A qualified clinician then uses the CyberKnife software to generate a treatment plan. The plan is used to match the desired radiation dose to the identified tumor location while limiting radiation exposure to the surrounding healthy tissue.

 Once the treatment plan has been developed, the patient is ready to undergo the CyberKnife procedure. After arriving at the CyberKnife Center, patients are comfortably positioned on the treatment table. Then the CyberKnife System’s computer-controlled robot will slowly move around the patient to the various locations from which it will deliver radiation to the tumor.

 Each treatment session will last between 30 and 90 minutes, depending on the type of tumor being treated. If treatment is being delivered in stages, patients will need to return for additional treatments over several days (typically no more than five), as determined by the patients doctor. Patients may experience some minimal side effects, but those often go away within the first week or two after treatment.

When is Cyberknife a Suitable Treatment Option?

Radiation therapy, surgery or chemotherapy are some of the traditional therapies that are used in combination with Cyberknife stereotactic radiosurgery. Following are the circumstances that requires Cyberknife system –

  • When a patient does not want to go through a traditional surgery
  • When a patient is unable to undergo a surgery
  • Recurrence of a tumor close to a significant structure like the spine, that previously received maximum dose of radiation
  • When surgery is not able to remove the entire diseased tissue
  • When tumor is located near to a significant structure like optic nerves where performing a traditional surgery can increase the risk of damage to these structures
  • When a surgical procedure is difficult to perform
