Cyberknife treatment is a minimally invasive surgery that is used for the treatment of cancer in any part of the human body, earlier thought to be inoperable or non treatable. It is an innovative robotic radio surgical procedure that is thought to be a better alternative to the conventional surgical procedures that are adopted for the elimination of cancer/tumor mass. However it can also be put to use for the correction of non cancerous conditions.
The procedure makes use of LINAC which is lightwear linear accelerator system, mounted on a robotic arm. This entire apparatus is made to deliver intense focused dose of radiation to the targeted site of tumor. These beamlets are hundreds in number and travel in multiple directions. However they all converge together on the tumor mass and magnify the dose. The cyberknife treatment also makes use of xray guided cameras to locate the actual site of the tumor so that the beam can be accurately targeted. The procedure is clubbed with software called as the synchrony system which enhances the robotic delivery system and helps in targeting the beam to a moving tumor mass, such as that of blood or lymph. The software can also detect the mass in motion if the patient breathes heavily or starts moving when the procedure is being carried out. This is the time when the sub-millmeter precision efficiency of the beam is put to use. With the maneuverability of the robotic arm, surgeons can administer multiple radiation beams from up to 1,200 different targeting positions and angles. All of the beams intersect within the tumor where the total dose is high enough to obliterate the cancer, while minimizing radiation exposure to surrounding healthy tissue.
Stereotactic radiosurgery or gamma knife surgery was the conventional procedure used. However, Cyberknife radiosurgery is one step ahead, and can be used in the treatment of:
Stereotactic radio surgery is the latest technology that uses many precisely focused radiation beams to treat cancerous and non cancerous anywhere in the human body. It is not a surgical procedure in the truest sense, since no incisions and suturing is needed. It works by targeting minute beams of radiation on the tumor mass and damaging the DNA of the cancer cells, bringing about cell death and disintegration of the tumor mass. This can be achieved in three different ways as follows:
|Cyberknife treatment||Conventional Radiotherapy|
|Administers small beams of radiation||Administers a broad beam of radiation|
|Direction of the beam is multi directional||Direction of the beam is usually from two sides only|
|Duration of the treatment is 3-5 days||Duration of the treatment is 6-8 weeks|
|Damage to the surrounding tissues is minimized||There is an equal chance of destroying the adjacent healthy tissues just like the cancer cells|
|Can detect the motion of the tumor mass when the patient breathes or moves during the dose administration and hence can change the direction of the beam||Cannot detect the change in motion of the mass, the direction of the beam remains the same|
|High success rates||Relatively lesser success rates|
Cyberknife and gamma knife are both stereotactic radio surgeries, however certain differences exist between the two. These are as follows:
|Cyberknife treatment||Gamma knife Treatment|
|The patient lies comfortably and the entire system moves around the patient||A large metal frame is mounted onto the head of the patient and stabilized with the help of screws|
|No general/local anesthesia or sedation is needed||Sedation and/or local/general anesthesia is needed depending upon the case|
|Approaches a tumor from over 1300 positions||Approaches a tumor from over 950 positions|
|Used for correction of cancerous and non cancerous conditions all over the body||Used for the correction of cancerous and non cancerous conditions in the brain and cervical spine only|
If you have or are experiencing any of the below mentioned points, you surely are an ideal candidate for the cyberknife treatment:
You recover from the procedure once you get discharged on the same day. However you may experience very minor side effects such as vomiting, nausea. If any major side effects occur then you are advised to see the doctor as soon as possible.
Success rate in cases of cyberknife treatment is directly proportional to the survival rate of the individual. Patients with low grade risk cancers treated with cyberknife have a 89 to 95 percent 5 year survival rate. Those with intermediate risk cancers have a 5 year survival rate of 80 to 83 percent.
You will be expected to pay a sum of 4,00,000 to 5,00,000 INR for the cyberknife treatment in India. This amount is like peanuts as compared to what you will be required to pay at the radio surgical hospitals abroad.
India is the leading country in terms of medical advancements in Asia. With the introduction and widespread use of cyberknife treatment in India, we at MedcureIndia assure a very personal touch and guidance regarding the course of cyberknife treatment for your concerned cancer or non cancerous lesion.
• Is cyberknife surgery included under Insurance?
Yes, it is included under insurance. You can find schemes in hospitals and banks and decide as per your wish.
• Will hair loss occur with cyberknife treatment?
There are 5 percent chances of hair loss occurring since the beam is highly selective in targeting.
• Is gamma knife similar to cyberknife?
No, gamma knife pertains to radio surgery of the brain and spinal tumors; cyber knife of the other hand is treatment for the cancers in the entire body.
