Overview of stereotactic body radiotherapy and the nursing role.

Stereotactic body radiotherapy (SBRT) is a rapidly emerging technology that enhances radiation therapy delivery. It allows for tightly conformed treatment fields and accurate delivery even with moving targets in the body. SBRT currently is used most commonly in treatment of medically inoperable stage I non-small cell lung cancers, as well as lung, liver, and spinal metastases. Studies to date are encouraging for increased local control with acceptable patient tolerance. This article familiarizes nurses with the use of this new technology and proposes the potential nursing role in maximizing patient preparation and follow-up care.
