Stereotactic body radiation therapy (SBRT) is a highly specialized technique of radiation therapy where high doses of radiation are precisely delivered to tumors over 1-5 sessions, compared to typical 4-8 weeks of daily sessions. SBRT is used most often to treat early stage lung cancer, tumors of the spine, liver, adrenal glands, and other organs.
The positioning and delivery is custom designed to each patient to minimize movement of the target area. Specialized molds and casts are used. Multiple beams of radiation, from different angles, are focused on the tumor. X-rays and/or CT scans are taken prior to delivering the radiation for accuracy.
SBRT has been proven to be highly successful in treating early stage lung tumors and is an option for patients who are looking to avoid or those who are not eligible for surgery.
