Radiosurgery for Brain Metastases
Except for solitary lesions causing mass effect, the treatment of brain metastases is primarily palliative. In the case of solitary metastases, the occurrence of longterm survival is not unheard of; but in general, the guiding philosophy is palliation, reversal of neurologic deficits and maintenance of quality of life and functional status. There has been disagreement regarding the total number...
متن کاملHyperArc VMAT planning for single and multiple brain metastases stereotactic radiosurgery: a new treatment planning approach
PURPOSE The HyperArc VMAT (HA-VMAT) planning approach was newly developed to fulfill the demands of dose delivery for brain metastases stereotactic radiosurgery. We compared the dosimetric parameters of the HA-VMAT plan with those of the conventional VMAT (C-VMAT). MATERIAL AND METHODS For 23 patients (1-4 brain metastases), C-VMAT and HA-VMAT plans with a prescription dose of 20-24 Gy were r...
متن کاملOptimization Algorithm for Single-Isocenter VMAT Stereotactic Radiosurgery for Multiple Brain Metastases
Objectives: Developing an optimal Stereotactic radiosurgery (SRS) plan for multiple brain metastases can be a labor intensive process. Single-isocenter multi-arc volumetrically modulated arc therapy (VMAT) has been used as an SRS technique, in which a Linear Accelerator (Linac) delivers targeted radiation along multiple arc angles as it rotates around the isocenter. Standardized arc angles with...
متن کاملPreoperative Stereotactic Radiosurgery of Brain Metastases: Preliminary Results
INTRODUCTION Preoperative stereotactic radiosurgery (pre-SRS) is a recent advancement in the strategy for brain metastasis (BM) management, and available data demonstrate the advantages of pre-SRS before postoperative radiation treatment, including lower rates of local toxicity, leptomeningeal progression, and a high percentage of local control. The authors presented the results of pre-SRS in ...
متن کاملStereotactic radiosurgery for brain metastases.
Worldwide, approximately 100,000 patients have undergone stereotactic radiosurgery for a variety of intracranial lesions, of which brain metastases represent the most common treatment indication. This article summarizes the major issues surrounding the management of brain metastases, and also analyzes 21 independent reports of Gamma Knife- or linear accelerator-based radiosurgery, representing ...
