Current uses and applications of stereotactic body radiation

Current uses and applications of stereotactic body radiation therapy.

Stereotactic body radiation therapy (SBRT) is a modality that delivers high doses of radiation to a well-defined tumor target in a single or a few fractions and with high precision, which significantly reduces the dose received by surrounding normal tissues. SBRT is indicated for inoperable, early stage (T1 and T2) primary non-small cell lung cancer, lung metastases with a controlled primary tumor, prostate tumors and oligometastatic disease. Despite the lack of long-term or phase III studies, efficacy results in local control are higher than 90%, with similar toxicity to that reported with conventional fractionated radiotherapy. This article describes SBRT technology and technique, along with clinical applications, indications and limitations of this therapeutic modality.
