Providing top-tier cancer treatment at a fraction of the cost Providing top-tier cancer treatment at a fraction of the costStereotactic Radiosurgery (SRS) is an extremely precise form of radiotherapy, originally developed to treat small tumors and functional abnormalities of the brain. Despite its name, and in comparison to traditional radiotherapy, SRS is a non-surgical procedure that delivers highly focused radiation in much higher doses and in only one or a few treatments. This treatment is made possible by the development of highly advanced technologies that allow maximum radiation doses to be delivered directly to the target, while minimizing the dose received by the surrounding healthy tissue, effectively destroying the tumor and achieving optimal local control. SRS is used to treat many types of brain conditions, including benign or malignant tumors, primary and metastatic, whether single or multiple. Additionally, it treats residual tumors after surgery, intracranial, orbital, and skull base tumors, as well as arteriovenous malformations (AVMs) and other conditions such as trigeminal neuralgia, etc.
The treatment team is composed of several specialized medical professionals, typically including radiation oncologists, a medical physicist, imaging specialists, a dosimetrist, and a radiation therapy nurse.
And in some cases a neurosurgeon, lead the treatment team and oversee the treatment process. They outline the target areas to be treated, determine the appropriate radiation dose, approve the treatment plan, and interpret the results of the radiosurgical procedures.
Interprets the images that identify the target areas to be treated in the brain or body.
Ensures the precise delivery of the radiation dose.
Under the physicist’s supervision, uses special computer software to prepare the treatment plan, calculating the exposures and beam configurations to treat the areas conformally to the prescribed dose.
Positions the patient on the treatment table and operates the machine from a nearby protected area. The technician can observe the patient through a window or via closed-circuit television and can communicate with the patient throughout the procedure.
The neurosurgeon and/or the radiation oncologist may assist in positioning the patient for treatment, and the imaging technician may operate the machine.
Evaluates the patient, provides information about the treatment, monitors the patient during treatment, and helps answer any questions after the procedure.
May participate alongside the radiation oncologist and neurosurgeon in the multidisciplinary team, considering various treatment options for individual cases and helping decide who might benefit from radiosurgery for brain lesions.
Special preparations required for the procedure
This procedure is usually performed on an outpatient basis. However, it is best to plan to spend half a day or more in the imaging department. You will be informed if it will be necessary for someone to accompany you and drive you home after the procedure.
You may be advised not to eat or drink anything after midnight the day before the treatment. Ask your doctor if you should continue taking your regular medications on the day of treatment and whether you should bring your medications with you to the procedure.
Radiation surgery treatments are similar to taking X-rays. Generally, X-rays cannot be seen, felt, or heard, except for patients receiving treatment in the brain, who may see lights while the machine is on, even with their eyes closed. The treatment itself does not cause any pain or discomfort. If you experience pain for other reasons, such as back pain or discomfort from the head device or immobilization device, please inform the medical or nursing staff.
