Both SRS and SBRT treatments are special techniques that rely on precise localization of target volumes based on 3D imaging. This allows clinicians to deliver higher than normal radiation dose in fewer fractions. At the University of Florida, single-fraction SRS for intracranial lesions is a joint effort between the departments of Radiation Oncology and Neurosurgery.
With more than 30 years of experience, the University of Florida is a renowned pioneer in linac-based SRS. This treatment is used to address a variety of benign, malignant, vascular, and functional lesions. Although it is called “radiosurgery”, SRS is a non-surgical, one-time outpatient treatment that is often an excellent alternative to surgery.
SBRT uses a similar approach for small, extracranial lesions. Through imaging guidance, SBRT allows highly precise delivery of high doses of radiation to small targets in fewer fractions, typically 5 fractions or less. SBRT has shown to provide excellent results for certain types of tumors in the lung, liver, and pancreas. The University of Florida is one of the first institutions that implemented this treatment technique and offered to our patients more than 10 years ago. All UF Radiation Oncology linacs are capable of delivering SBRT with 3D conformal Arc, IMRT, or VMAT delivery techniques.
