... Abstract Objective: To evaluate radiosurgery outcomes in vestibularschwannoma (VS) patients who have undergoneprior tumor treatment. Methods: Retrospective review of55 consecutive VS patients having radiosurgery for recurrent(n = 22) or residual tumors (n = 33) after prior microsurgery.The...

... radiosurgery could potentially be done. This led to the first Gamma Knife installation in 1968. Over the subsequent 50 years Gamma Knife surgery has evolved to cover much of what is done in neurosurgery and there are more than 330 Gamma Knife centers all over the world. By the end of 2017 more than 1.2 million...

... Abstract For more than 65 years localization of brain targets suitable for stereotactic radiosurgery has been performed after application of an intracranial guiding device to the cranial vault. After imaging and dose planning the same frame is used to secure the target at the focus...

... Abstract Stereotactic image acquisition is an important aspect of radiosurgery dose planning. Treatment planning is usually performed with magnetic resonance imaging (MRI) and computed tomography (CT). While CT is considered most accurate, MRI provides superior soft tissue contrast needed...

... Abstract An electronic registry is essential for the evaluation of quality of data collection and the clinical outcome related to any medical procedure. At our institution, we developed a new comprehensive electronic quality assurance registry for Gamma Knife radiosurgery. A task force...

... a significant dose to the patient. The excited state of 60 Ni are where the gamma rays originate from the beta decay of 60 Co. The gamma rays used for stereotactic radiosurgery are emitted with energies of 1.1732 and 1.3325 MeV, and the mean energy is around 1.25 MeV. 60 Co decays with a half-life of 5.26...

... Abstract Nursing management of radiosurgery patients begins on the day they select radiosurgery as their management option in the clinic. During their clinic visit, the patient also meets with a dedicated Gamma Knife nurse who completes a nursing assessment and a screening brain imaging...

... Abstract At UPMC, Leksell radiosurgery (LR) has been used in over 15,000 patients during the 31 years since the first Gamma Knife was installed. Until the installation of the ICON® model which allows mask-based cranial fixation as the stereotactic fixation system in 10% of LR-appropriate...

... compression. Gamma Knife® stereotactic radiosurgery (GKSRS) is a valuable primary management modality for vestibular schwannomas (VS) that has been actively evolving from a capability standpoint. GKSRS delivers the radiation in a single procedure due to the unparalleled accuracy and dose fall off...

... Abstract Since its first reported use in 1976 in Sweden, Gamma Knife (GK) radiosurgery has become an accepted treatment option for intracranial meningioma, either upfront, in combination with planned subtotal resection, or as adjuvant/salvage treatment. Initially, GK was used in patients unfit...

... Abstract Stereotactic radiosurgery (SRS) is an effective treatment for patients with multiple brain metastases. Three decades of increasingly powerful scientific studies have shown that SRS improves outcomes and reduces toxicity when it replaces whole-brain radiation therapy (WBRT). Expert...

... Abstract The JLGK0901 study showed the non-inferiority of stereotactic radiosurgery (SRS) alone as the initial treatment for 5–10 as compared to 2–4 brain metastases (BM) in terms of overall survival and most secondary endpoints [Lancet Oncol 2014;15:387–395]. A trend for patients with 5–10...

... and/or surgical decompressive therapy, in patients with residual, recurrent, or refractory disease, decades of data support management with stereotactic radiosurgery. This modality offers favorable local tumor control, endocrine remission rates, and infrequent toxicity. In the future, this alternative...
