Stereotactic body radiation therapy (SBRT) involves the precise delivery of highly conformal ablative doses of radiation therapy to targets outside of the brain. This innovative treatment modality was first developed in human therapy as an adaptation of intracranial stereotactic radiosurgery (SRS) and made possible by advances in tumor motion gating and image verification.

Stereotactic radiation has been evaluated in multiple tumor types with central nervous system, nasal and bone tumors being the most studied in veterinary patients. In addition, publications on heart base, injection site sarcomas and adrenal gland tumors have been published in the last 8 years.

To date there is a paucity of literature for stereotactic body radiation to intra-abdominal targets in veterinary medicine. This presentation aims to discuss the role of stereotactic body radiation therapy for intra-abdominal tumors in veterinary medicine through the evaluation of the current literature, case examples and clinical experience, and human radiation therapy protocols. Topics of importance include tumor motion, side effects and possible outcomes.
