Gamma knife surgery for facial nerve schwannomas. [PDF]

, 2007
peer reviewedRadical resection of facial nerve schwannomas classically implies a high risk of severe facial palsy. Owing to the rarity of facial palsy after gamma knife surgery (GKS) of vestibular schwannomas, functional evaluation after GKS seems ...

Lung V5 and Planning Target Volume/Lung Volume Ratio as Independent Risk Factors for ≥Grade 2 Radiation Pneumonitis after Moderately Hypofractionated Radiotherapy: A Retrospective Study

Asia-Pacific Journal of Clinical Oncology, EarlyView.
Lung V5 and the planning target volume/lung volume ratio were identified as independent dosimetric risk factors for clinically significant radiation pneumonitis following moderately hypofractionated radiotherapy for lung cancer. Maintaining V5 < 35% may help mitigate this risk in clinical practice.

Long‐run confidence: Estimating uncertainty when using long‐run multipliers

American Journal of Political Science, EarlyView.
Abstract Researchers are often interested in the long‐run relationship (LRR) between variables where the dependent variable has dynamic properties. Though determining the long‐run multiplier (LRM) for an independent variable is straightforward, correctly estimating the significance of the LRM is often difficult, especially when time series are short ...

Circumscribed Meningeal Melanocytic Neoplasms: CNS WHO Grade, Molecular Profile, and Clinical Outcomes

Brain Pathology, EarlyView.
In this study including 31 circumscribed meningeal melanocytic neoplasms (melanocytoma, intermediate‐grade melanocytic tumor [IMT], and melanoma), overall survival (OS) differed significantly among the groups, with melanoma showing significantly worse OS than melanocytoma and IMT showing intermediate OS between melanocytoma and melanoma.

Assessing the impact of distortion correction on Gamma Knife radiosurgery for multiple metastasis: Volumetric and dosimetric analysis

Brain and Spine
Introduction: Magnetic resonance imaging (MRI) is a robust neuroimaging technique and is the preferred method for stereotactic radiosurgery (SRS) planning. However, MRI data always contain distortions caused by hardware and patient factors.
