Stereotactic Radio Therapy (SRT) Cost in Egypt

To accurately position the patient and deliver radiation to a well-defined malignant tumor, stereotactic radiation therapy, or SRT, is a type of external radiation therapy. With SRT, the entire radiation dose is split up into multiple doses that are administered over a few days. When treating brain tumors and other brain illnesses, stereotactic radiation therapy is usually utilized as part of a comprehensive treatment regimen.

Even though SRT's overall dose may be higher than SRS's, each day's dose administration will be substantially lower. Known as stereotactic ablative body radiation (SABR) or stereotactic body radiation therapy (SBRT), both are used to treat localized cancers in the brain and, more recently, in the body.

The excessive dose administered in SRS and SRT requires the patient to be positioned very precisely. For each patient, a customized mask or positioning device is created at the moment of CT imaging to achieve this. This makes it possible to precisely position the patient, facilitating the sub-millimeter radiation administration.

What are the types of SRT?

A variety of devices are employed in the delivery of stereotactic radiotherapy, such as:

• Linear Accelerators (LINAC)- These devices target the tumor with high-energy electrons or X-rays.
• CyberKnife- A robotic radiosurgery system with sub-millimeter accuracy that can deliver radiation from different directions.
• Gamma Knife- Targets brain or head and neck cancers with concentrated gamma radiation beams.

SRT is commonly used to treat tumors of small to intermediate size in the pancreas, brain, spine, lung, liver, prostate, and other body areas. It works especially well for tumors that are hard to operate on because of their location or the patient's general health.
