Single fraction stereotactic radiosurgery for multiple brain metastases
Introduction Due to the neurocognitive side effects of whole brain radiation therapy (WBRT), stereotactic radiosurgery (SRS) is being used with increasing frequency. The use of SRS is expanding for patients with multiple (>4) brain metastases (BM). This study summarizes our institutional experience with single-fraction, linear-accelerator-based SRS for multiple BM. Methods and materials All p...
متن کاملWe’ve Got a Treatment, but What’s the Disease?
Hypofractionation has been a recurring issue during the near century-long history of radiation oncology. Coutard first introduced protracted dose-fraction regimens that uniquely allowed for the control of “deep” tumors. Subsequent studies have consistently shown that hypofractionation leads to an increase in complication rates and a paradoxical decrease in cure rates. There have, nonetheless, b...

متن کاملDosimetric superiority of flattening filter free beams for single-fraction stereotactic radiosurgery in single brain metastasis
For single-fraction stereotactic radiosurgery (SRS) using linac in brain metastases, more accurate treatment delivery with higher tumor absorbed doses and lower absorbed doses to normal tissues remains an enormous challenge. The purpose of this study was to investigate the dosimetric superiority in flattening filter free beams (FFF) for volumetric modulated arc therapy (VMAT) in single brain me...
متن کاملHypofractionated radiosurgery for intact or resected brain metastases: defining the optimal dose and fractionation
BACKGROUND Hypofractionated Radiosurgery (HR) is a therapeutic option for delivering partial brain radiotherapy (RT) to large brain metastases or resection cavities otherwise not amenable to single fraction radiosurgery (SRS). The use, safety and efficacy of HR for brain metastases is not well characterized and the optimal RT dose-fractionation schedule is undefined. METHODS Forty-two patient...
