Stereotactic Radiotherapy in the Treatment of Prostate Cancer

Stereotactic body radiotherapy (SBRT) is a technologically sophisticated form of radiotherapy and well-established treatment option for patients with a low- and intermediate-risk prostate cancer. Stereotactic body radiation therapy or radiotherapy (SBRT) and stereotactic ablative radiation therapy or radiotherapy (SABR) both describe an advanced form of radiation therapy that is used to treat many different types of cancer. The two terms are interchangeable which are usually conducted in one, three, or five fractions. SBRT can be used as therapy for radical treatment, or as a boost after IMRT (intensity-modulated radiation therapy) and IGRT—image-guided radiation therapy or conventional radiotherapy. It also can be used as boost therapy for patient with high-risk prostate.
