Stereotactic body radiotherapy is like Stereotactic Radiosurgery in that it is using very precise beams of radiation to treat targets reducing need for standard surgery. Whereas Stereotractic Radiosurgery is focused on the brain, stereotractic body radiotherapy is focused on other areas of the body.
Stereotactic Body Radiation Therapy, also known as stereotactic ablative radiotherapy, or stereotactic ablative body radiation (SABR) precisely targets tumors with very high doses of radiation. It is a type of radiation therapy that uses high doses of radiation delivered to a small, well-defined target in the body with great precision. SBRT is often used to treat tumors that are difficult to reach with surgery, or for patients who are not good candidates for surgery. It is also used to treat tumors in the lungs, liver, spine, and other parts of the body. The radiation beams used in SBRT are highly focused, and the treatment is typically completed in one to five sessions, depending on the size and location of the tumor. Because the radiation dose is so high, SBRT is usually reserved for tumors that are small in size, and the treatment is carefully planned to minimize the exposure of nearby healthy tissues and organs to radiation.
SBRT is an effective and safe treatment option for many types of cancer, and it can often provide a high degree of tumor control while minimizing the risk of side effects. SBRT uses several radiation beams of various intensities aimed at the tumor from different angles. It is important that the entire SBRT workflow be systematically optimized and that appropriate quality assurance (QA) measures are implemented.
