Gamma Knife Surgery
  • Cost Comparison, Complication, Risk and Recovery

About Gamma Knife Surgery
  • In Gamma Knife surgery, specialized equipment
    focuses close to 200 tiny beams of radiation on a
    tumor or other target. However, each beam has
    very little effect on the brain tissue as it
    passes through a strong dose of radiation is
    delivered to the site where all the beams meet.
  • The precision of Gamma Knife surgery results in
    minimal damage to healthy tissues surrounding the
    target. In some cases, Gamma Knife surgery may
    have a lower risk of side effects compared with
    other types of radiation therapy. Also, Gamma
    Knife surgery is often a safer option than is
    traditional brain surgery.

Conditions Treated with Gamma Knife Surgery
  1. Small intracranial AVMs (Arteriovenous
    Malformation, an artery and vein that have not
    formed properly) or cavernous angiomas (not
    greater than 4 cm)
  2. Benign tumors including acoustic
    neuromas, meningiomas, and pituitary adenomas
    craniopharyngiomas
  3. Tumors located at the base of the skull in the
    pineal region
  4. Metastatic brain lesions  other partially
    resected tumors
  5. Trigeminal Neuralgia
  6. Parkinson's disease or other movement disorders
  7. Medically intractable epilepsy
  8. Intractable pain in patients with disseminated
    cancer

How does Gamma Knife radio surgery work?
  • Gamma Knife treatment generally involves these
    steps
  • Head frame placement
  • In order to keep the head from moving during
    treatment, a box-shaped frame is attached to the
    head. Pins designed specifically for this purpose
    fasten the head frame to the skull.
  • Tumor or lesion location imaging
  • Once the head frame is in place, the exact
    location of the lesion to be treated will be
    determined using computed tomography (CT scan)
    or magnetic resonance imaging (MRI).

How does Gamma Knife radio surgery work?
  • Radiation dose planning
  • After the CT or MRI scan has been completed, the
    radiation therapy team will determine the
    treatment plan. The results of the imaging scan,
    along with other information, will be used by a
    medical physicist to determine the best
    treatment.
  • Radiation treatment
  • After being positioned for the treatment, a type
    of helmet with many hundreds of holes in it is
    placed over the head frame. These holes help to
    focus the radiation beams on the target.
    Treatment will last a few minutes up to a few
    hours, depending on the type and location of the
    area being treated. Generally, only one treatment
    session is required for a lesion.

Two other types of radio surgery are
  • Linear accelerator (LINAC) systems
  • Linear accelerator (LINAC) systems use high
    energy x-rays to treat a tumor. Some general
    types of LINAC systems include CyberKnife,
    X-Knife, Novalis, and Peacock. In addition to
    using x-rays rather than gamma rays, LINAC
    systems also differ from the Gamma Knife in that
    the machinery moves around the patient during
    treatment. For this reason, Linear accelerator
    (LINAC) systems are able to treat larger tumors
    and larger affected areas than the Gamma Knife.
    Areas other than the brain can be treated with a
    LINAC system.

Two other types of radio surgery are
  • Proton beam therapy or cyclotron
  • Proton beam therapy is a type of particle beam
    radiation therapy. Rather than using rays of
    radiation, such as gamma rays or x-rays, particle
    beam therapy uses particles such as protons or
    neutrons. Proton beam therapy is the most
    widely-used type of particle beam therapy. Proton
    beam therapy may be used for radio surgery
    procedures or for fractionated radiotherapy
    (several smaller doses of radiation over a
    certain period of time).There are only a few
    facilities in North America that provide proton
    beam therapy.

Which is the best hospital for Gamma Knife Radio
Surgery in India?
  • Medanta - The Medicity is the best hospital for
    Gamma Knife Radio Surgery in India.

9
What is the cost of Gamma knife Radio Surgery in
India?
  • Cost of Gamma Knife Radio Surgery in India is
    very less as compared to the other countries. The
    cost of Gamma Knife Radio Surgery in India will
    be approx Rs. 2 Lakhs.
  • What is the cost comparison of Gamma knife Radio
    Surgery in India to other countries?
  • Cost of Gamma Knife Radio Surgery in USA will
    cost around Rs. 4 Lakhs (6,000).
  • Cost of Gamma Knife Radio Surgery in UK will cost
    around Rs. 4 Lakhs (6,000).
  • Cost of Gamma Knife Radio Surgery in India will
    cost around Rs. 2 Lakhs (3,000).
