Understanding Your Treatment Options

BRACHYTHERAPY also known as Internal Gamma Knife
or Nuclear Particle Knife
(A Type of Internal Radiation Therapy for Carcinomas
and Sarcomas)
This treatment is one of the most advanced treatment methods for
nucleide to treat cancer (brachytherapy).

This type of treatment has been used extensively in Seattle , USA
for treating
early stage prostate cancer. Our hospital was the first
in Guangzhou to introduce and have been implementing this
method of treatment and for the last 3 years with great success.

Treatment Principle

  • Brachytherapy uses internal radiation to destroy cancer cells
    and shrink tumors.
  • The radiation source, which looks like rice is made of titanium.
    Inside of it is a half-life iodine with an isotope of 125. This
    seed source or micro-radiator emits low-energy radiation
    continuously after it is planted accurately into the tumor or
    the surrounding area/tissue attacked by cancer.
  • The radioactive energy causes maximum destruction to the
    tumor tissue with little or no injury to the normal tissue
  • This form of internal radiation is far superior to external
    radiation which is used in conventional radiotherapy
  • With the help of a  B ultrasonic or CT scanner, a 3-
    dimensional particle is transplanted into the area to be
    treated. The planting system is able to calculate the quantity
    required of the particle, its position and dosage amount
    based on the size of the tumor. Such information is necessary
    to let the dosage field developed by the radiation to form a
    ‘hot zone’ which is compatible with the tumor treating zone in
    order to kill the tumor. For normal tissue, particular organs
    situated in the ‘cold zone’ of the dosage field are not affected
    or damaged

Features and Benefits of the treatment

  1. A ‘punctured particle’ needle is used to implant the particle
    into the body. This is a simple operation and causes minimal
    damage to the patient.
  2. This treatment can be used on any and every part of the
    body which is accessible to the reach of the punctured
    particle needle.
  3. This treatment method can be used for cases which have not
    responded to other methods
  4. The low-energy radiation which is emitted continuously
    effectively destroys the cancer cells. A sufficient dosage and
    appropriate generation time period result in the total
    eradication of the cancer cells and make for total recovery.

Application Range

This method can be used for brain tumor, nasopharyngeal
carcinoma, lung cancer, cancer of esophagus, lymphoma, breast
cancer, prostate cancer, thyroid gland cancer, cervix cancer,
liver cancer, bone cancer, etc. Even cancers which have
after operation can be treated.

A Short Summary of the
Brachytherapy treatment process:

Before treatment:

  • Take a PET/CT scan.
  • After, our doctors will plan your treatment and brief you on
    the course of treatment.

During treatment:

  • A small tube called a catheter is placed into the body in the
    vicinity of the tumor.
  • Then the titanium pellets are inserted through the catheter
    to destroy cancer cells.
  • Over a number of days the radiation gets weaker until there
    is no more radiation
