Before radiation treatment begins, a patient has a preliminary appointment that allows doctors to prescribe the proper dosage and delivery of radiation.
Once this "set-up" is complete and special blocks have been made to shield healthy organs from the radiation, treatment can be scheduled.
Patients who can receive stereotactic radiosurgery
Radiosurgery is limited to lesions that are well-defined and no larger than three to four centimeters. The location of the lesion is also important. For example, lesions too close to radiosensitive structures, such as the optic nerve, are not good targets for radiosurgery.
How stereotactic radiosurgery works
Stereotactic radiosurgery uses sophisticated computerized imaging to precisely focus a narrow X-ray beam. Using this method, it is possible to effectively destroy small tumors or close down abnormal blood vessels.
This technique, which is accurate to one millimeter or less, does not require surgery and can be done on an outpatient basis. Radiation can be delivered using either the frameless CyberKnife, or a framed system.
Stereotactic radiosurgery includes the participation of both the surgical and radiation oncology teams who work together to evaluate and treat each patient.
Fewer side effects: The ability to spare healthy tissue while intensifying the radiation dose is the primary advantage of SABR over other modalities, particularly when critical structures are located near the treatment area.
Highly effective and accurate: For most indications, local tumor control rates of 90% can be achieved. Stereotactic ablative radiotherapy (SABR) uses the latest image guidance technologies to destroy tumors with millimeter-scale accuracy.
Non-invasive: SABR is non-invasive and comfortable.
