Stereotactic Body Radiation Therapy

SBRT is a form of external beam radiation therapy that delivers a higher dose per treatment than what is usually given with conventional external beam radiation, over a shorter time period. SBRT is typically completed within three to five treatments. Generally, higher doses of radiation result in greater side effects, but with SBRT, side effects are limited because the treatment volumes are small. SBRT is particularly useful for treating small tumors in the lung or elsewhere in the body and is increasingly used in the treatment of prostate cancer. Additionally, patients with a limited volume of metastatic disease, known as oligometastatic disease, can benefit from SBRT to the metastatic sites.
