Stereotactic Radiotherapy delivers radiotherapy from a variety of angles all over the body. At the tumor, the beams come together. This means that the tumor gets a high dosage of radiation while the surrounding tissues get a considerably lesser amount. As a result, the likelihood of side effects is reduced. In most cases, you will receive between one and eight treatments. Stereotactic radiotherapy is referred to by a variety of terms, which can be confusing. Stereotactic body radiation (SBRT) or stereotactic ablative radiotherapy are two terms for stereotactic treatment for the body (SABR). Stereotactic radio-surgery could be used to describe stereotactic radiation for the brain (SRS). This is normally a one-time procedure. Stereotactic treatment refers to when you receive multiple treatments to the brain.
When you might have stereotactic radiotherapy :This type of radiotherapy is mainly used to treat very small cancers, including:
- Brian tumors
- Cancer of the lung in early stage
- Cancer that started in the liver or cancer that has spread to the liver
- Spinal cord tumors
- Cancer spread to the brain (Brain mets)
Stereotactic radiation can also be utilized to treat areas of the body that have already been treated with radiation. Someone who has had radiotherapy to their pelvis, for example, will almost probably be unable to have it done again. However, because stereotactic treatment is so precise, re-treatment is frequently possible.
Other cancers that might benefit from stereotactic therapy are being studied.
A lot of steps are involved in SRT planning.
The first step is a CT scan at the radiation department. MRI or PET examinations may be used to examine the part of your body that will be treated. The information from these scans is directly sent into the computer that calculates radiation doses. After that, the computer system generates radiation beams that closely mirror the tumour's shape. Your doctor will make sure that all cancer cells are contained inside the radiation field, as well as that as much healthy tissue as possible is spared. As a result, the chances of experiencing side effects are minimised.
