Introduction

 

The CyberKnife VSI Robotic Radiosurgery System is a non-invasive alternative to surgery for the treatment of both cancerous and non-cancerous tumours anywhere in the body including the Prostate, Lung, Brain, Spine, Liver, Pancreas and Kidney. The treatment  delivering beams of high dose radiation to tumours with extreme accuracy  offers new hope to patients worldwide.

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

 

 
 
 

What is the Treatment Process?

 

After or during diagnosis, physicians determine if a patient will benefit from the CyberKnife VSI treatment. CyberKnife VSI treatment involves a team approach in which various medical professionals collabrate so as to develop a treatment plan tailored as per the patient's needs.

 
The CyberKnife VSI treatment process involves the following steps:
 
 
Step 1
 
EVALUATION

Post diagnosis, the patient may be recommended the CyberKnife VSI treatment. Though the course may vary based on patient's specific requirements, a team of clinicians including Radiation Oncologists, Surgeons, Medical Physicists, Radiation Technicians and Nurse Coordinators play a key role.

 
Step 2
 
FIDUCIAL PLACEMENT

Depending on the type and location of the tumor, our team recommends placement of Fiducials, which are small gold markers inserted near the tumor, to help identify the exact location of the tumor during treatment. Not all treatments require Fiducial markers. The determination is made based on the density, size and location of the tumor.

 
Step 3
 
IMAGING

Before the treatment begins; an MRI, CT or a CT/PET scan is taken to determine the size, shape and location of the tumor.

 
Step 4
 
TREATMENT PLANNING

Using images from CT scan, data is digitally transferred to the CyberKnife VSI system's treatment planning workstation, where a qualified physician identifies the tumor to be targeted and its surrounding vital structures to be protected. This plan is designed to match the desired radiation for the tumor location and limit radiation exposure to the surrounding healthy tissues. This radiation planning aims to precisely pinpont the radiation dose close to the tumor and limit radiation exposure to surrounding healthy tissues, thus minimizing the collateral damage adequately.

 
Step 5
 
TREATMENT

Once the treatment plan is developed, the CyberKnife VSI treatment begins. At the CyberKnife VSI center, the patient is comfortably positioned on the treatment table, while the CyberKnife VSI's computer-controlled robot carefully moves around to deliver radiation at various locations, as prescribed in the prefixed treatment plan.

At the same time, the CyberKnife VSI system takes continual x-ray images, that provide real- time information about the location of the tumor and enables the system to dynamically track and correct any movement of the tumor. Depending on the type and location of the tumor, the patient undergoes 1-5 treatment sessions,each typically lasting an hour or less.

 
Step 6
 
RECOVERY

Most CyberKnife VSI patients do not experience side effects. Depending on the type of treatment one receives, side effects vary. Some side effects experienced by the patients are mild and do not require any intervention.

Patients should consult their doctor and discuss their side effects, that may occur and learn about their potential risks.
