Accuray reports new data from multicenter analysis of SRS and FSRT

Accuray (ARAY) announced international retrospective multicenter analysis found that radiosurgery, or SRS, and fractionated stereotactic radiotherapy, or FSRT, delivered with the CyberKnife System, can provide an effective and time-saving treatment option for brainstem metastases, or BSM. The nine institution study results, published in the International Journal of Cancer, “underscore the long-term benefits in local control and the robust safety profile despite the delicate location of the treated metastases.” SRS and FSRT – also referred to as fractionated radiosurgery – are advanced forms of radiation therapy. SRS delivers a high dose of radiation in one session, while FSRT divides the total treatment dose into multiple, smaller doses given over several days. Both techniques provide medical care teams with the ability to deliver extremely precise, very targeted doses of radiotherapy, typically to small, specific areas within the body, usually in the brain. In the reported analysis, 136 patients who received treatment in one to five sessions were analyzed; 69.4 percent received radiotherapy in just one treatment dose.
