Single-fraction image-guided extracranial radiosurgery for recurrent and metastatic abdominal and pelvic cancers: short-term local control, metabolic response, and toxicity.

Purpose: Extracranial radiosurgery (ECRS) is a novel treatment for inoperable recurrent or metastatic abdominopelvic cancers. However, local control, metabolic response, and acute toxicity remain undefined. We therefore analyzed these endpoints in patients treated with single-fraction image-guided ECRS at Emory University.
