Observational StudyWHO grade of intracranial meningiomas differs with respect to patient's age, location, tumor size and peritumoral edema.
To analyse whether the WHO grade of intracranial meningiomas differs itself depending on patients and meningioma characteristics at diagnosis. ⋯ In this series atypical meningioma was associated with younger age, location on the convexity, larger tumor size and more peritumoral edema.

Risk factors for intraoperative stimulation-related seizures during awake surgery: an analysis of 109 consecutive patients.
During surgery for lesions in eloquent areas the goal is to achieve the widest resection possible, without loss of neurological function. Intraoperative seizures may lead to abandonment of the procedure or damages to the patient. Awareness regarding the predictors of IOS would help the surgeon. The aim of this retrospective study was to identify the factors associated with the occurrence of IOS in patients who underwent awake surgery for removal of gliomas in eloquent areas. ⋯ The current series add some hints to the poorly studied IOS risk during awake surgery. The risk of IOS appears to be relatively higher in patients with anteriorly located tumors and in patients operated without intraoperative brain activity monitoring and different patterns of stimulation for language and sensory-motor mapping. Further studies are needed to clarify the role of intraoperative techniques.

Neurological and related adverse events in immune checkpoint inhibitors: a pharmacovigilance study from the Japanese Adverse Drug Event Report database.
Immune checkpoint inhibitors (ICPI), a breakthrough immunotherapy for cancer, can cause serious neurological adverse events (AEs). We aimed to investigate the characteristics of the neurological and related AEs associated with ICPI treatment, using a large pharmacovigilance database from Japan. ⋯ Our results showed characteristic features of neurological and related AEs associated with each ICPI subtype, reported in a large number of Japanese patients. This would help in prompt identification and treatment of neurological AEs associated with ICPI treatment.

Initial biopsy and early re-resection practices in the treatment of glioblastoma among AANS/CNS tumor section surgeons.
Surgical management strategies for glioblastoma (GBM) may differ among neurosurgeons with initial biopsy of suspected tumors and the need for early re-resection of tumors within 30 days of initial surgery. This study was initiated by the American Association of Neurological Surgeons (AANS) and Congress of Neurological Surgeons (CNS) Tumor Section's interest in understanding the rates at which pre- and post-resection procedures, specifically biopsies prior to definitive resection and early re-resections, are performed by U.S. neurosurgeons in the management of GBM. ⋯ Further studies are needed to confirm the results of this study, which shows low rates of stereotactic and open biopsy and early re-resection procedures performed among neurosurgeons. These rates may help form guidelines in the treatment of GBM and encourage the use of surgical adjuncts that increase the extent of resection of these tumors, thereby reducing rates of early recurrence.

Multicenter Study Observational StudyStereotactic radiosurgery in elderly patients with brain metastases: comparison with non-elderly patients using database of a multi-institutional prospective observational study (JLGK0901-Elderly).
Stereotactic radiosurgery (SRS) has been increasingly used for elderly patients with brain metastases (BMs). However, no studies based on a large sample size have been reported. To compare SRS treatment results between elderly and non-elderly patients, we performed a subset study of elderly patients using our prospectively-accumulated multi-institution study database (JLGK0901 Study, Lancet Oncol 15:387-395, 2014). ⋯ We conclude that elderly BM patients are not unfavorable candidates for SRS alone treatment.
