OBJECT A prospectively collected cohort of 77 patients who underwent definitive radiosurgery between 2002 and 2010 for melanoma brain metastases was retrospectively reviewed to assess the impact of ipilimumab use and other clinical variables on survival. METHODS The authors conducted an institutional review board-approved chart review to assess patient(More)
BACKGROUND Injuries represent a significant and growing public health concern in China. This Review was conducted to document the characteristics of injured patients presenting to the emergency department of Chinese hospitals and to assess of the nature of information collected and reported in published surveillance studies. METHODS A systematic search of(More)
We have shown that inhibition of mTOR in granulosa cells and ovarian follicles results in compromised granulosa proliferation and reduced follicle growth. Further analysis here using spontaneously immortalized rat granulosa cells has revealed that mTOR pathway activity is enhanced during M-phase of the cell cycle. mTOR specific phosphorylation of p70S6(More)
OBJECT Radiation necrosis (RN), or its imaging equivalent, treatment-related imaging changes (TRIC), is an inflammatory reaction to high-dose radiation in the brain. The authors sought to investigate the hypothesis that immunotherapy increases the risk of developing RN/TRIC after stereotactic Gamma Knife (GK) radiosurgery for brain metastases. METHODS A(More)
OBJECT Facial nerve schwannomas (FNSs) are rare intracranial tumors, and the optimal management of these tumors remains unclear. Resection can be undertaken, but the tumor's intimate association with the facial nerve makes resection with neurological preservation quite challenging. Stereotactic radiosurgery (SRS) has been used to treat FNSs, and this study(More)
OBJECT Posterior fossa meningiomas represent a common yet challenging clinical entity. They are often associated with neurovascular structures and adjacent to the brainstem. Resection can be undertaken for posterior fossa meningiomas, but residual or recurrent tumor is frequent. Stereotactic radiosurgery (SRS) has been used to treat meningiomas, and this(More)
PURPOSE Limited data are available to help inform decisions about stereotactic radiosurgery for patients with ≥5 brain metastases. We therefore performed a retrospective analysis of patients treated for >5 brain metastases. MATERIALS/METHODS Patients who underwent treatment for ≥5 brain metastases from October 2000 to September 2010 were identified.(More)
Despite a known optimal treatment protocol for the management of glioblastoma multiforme (GBM), many patients fail to receive complete surgical resection or post-operative radiation therapy (PORT). The underlying reasons behind this disparity are unclear. Our study investigates the influence of regional health system resources on the surgical management and(More)
Dose selection for brain metastasis radiosurgery is based largely upon clinical data obtained over a half century of radiosurgical treatments for various benign and malignant conditions. It is expected that within the entire radiosurgical process, the step of dose selection will occur within a framework of accurate calibration of dose delivery and accurate(More)
