BACKGROUND: Brain metastases commonly manifest in cancer patients, with approximately 20-50% presenting with one intracranial lesion. Among patients with one, small brain metastasis and controlled or absent extracranial disease, it remains unclear if aggressive intracranial management utilizing neurosurgical resection and cavity stereotactic radiation (SRS/SRT) rather than SRS/SRT alone is beneficial. In patients with controlled or absent extracranial disease and one brain metastasis ≤2 cm in size, we evaluated the impact of surgery plus SRS/SRT compared to SRS/SRT on oncologic outcomes including overall survival...

Nader Sanai
For the neurosurgical oncologist, a specialty practice in gliomas represents an intersection of tailored surgical approaches, emerging intraoperative technologies, expanding surgical trial portfolios, and new paradigms in glioma biology. Assembling these disparate pieces into a cohesive career trajectory is a difficult task but ultimately enables the subspecialist to navigate all domains relevant to improving glioma patient outcomes. Within the larger clinical and basic science community, thoughtful integration and intensive collaborations are essential mechanisms when building a multidisciplinary glioma program...

BACKGROUND AND IMPORTANCE: Stereotactic brain biopsy (SB) is an important part of the neurosurgical armamentarium, with the possibility of achieving histopathological diagnosis in otherwise inaccessible lesions of the brain. Nevertheless, the procedure is not without the risk of morbidity, which is especially true for lesions in eloquent parts of the brain, where even a minor adverse event can result in significant deficits. Navigated transcranial magnetic stimulation (nTMS) is widely used to chart lesions in eloquent areas, successfully guiding maximal safe resection, while its potential role in aiding with the planning of a stereotactic biopsy is so far unexplored...

INTRODUCTION: Seizures are an important cause of morbidity in patients with low grade gliomas with approximately 40% of cases drug resistant. The pathogenesis is quite complex and poorly understood. The treatment aims vary between almost purely epilepsy considerations and those that are primarily oncologic. AIM: To determine whether patients who present with seizures and are found to have a low grade glioma have better outcomes when managed through a specialized epilepsy unit compared to the general neurosurgical service...

Background: Cerebral tumors are associated with high rates of anxiety, depression and reduced health related quality of life. Nevertheless psychooncological screening instruments are neither implemented nor well defined in the daily routine of neurosurgical departments. Therefore, we tried (1) to identify a suitable screening algorithm for neurosurgical patients, (2) to define clinical risk factors for increased distress and (3) to analyze the optimal screening time point. Results: Between October 2013 and January 2015 472 elective neurosurgical in-patients (median age 55...

Primary brain tumors are a leading cause of cancer-related morbidity and mortality in children. Glioblastoma (GBM) is a high-grade astrocytoma that occurs in both children and adults and is associated with a poor prognosis. Despite extensive study in recent years, the clinical management of these tumors has remained largely unchanged, consisting of surgical resection, conventional chemotherapy, and radiotherapy. Although the etiology and genomic drivers in GBM are diverse, constitutional mismatch repair-deficiency (CMMRD) syndrome is a rare, recessively inherited disease with a predisposition to gliomagenesis...

INTRODUCTION: Glioblastoma multiforme (GBM) is the most common malignant primary brain tumor in adults with peak incidence in patients older than 65 years. These patients are mostly underrepresented in clinical trials and often undertreated due to concomitant diseases. Recently, different therapeutic approaches for elderly patients with GBM were discussed. To date, there is no defined standard treatment. The aim of the present study is to evaluate the functional and oncological outcome in surgical treatment of elderly patients...

BACKGROUND: In recent years several techniques have been proposed with the aim of improving tumors visualization and extent of resection and, among them, the use of photosensitive dyes is gaining great interest. Regarding the application of the two most used dyes, 5-aminolevulinic acid (5-ALA) and sodium fluorescein (SF), there is still a lack of shared and established protocols among different centers. The main objective of the present study was to evaluate the current practice of fluorescence-guided techniques in neuro-oncological surgery in Europe...

OBJECTIVE The best management of veins encountered during the neurosurgical approach is still a matter of debate. Even if venous sacrifice were to lead to devastating consequences, under certain circumstances, it might prove to be desirable, enlarging the surgical field or increasing the extent of resection in tumor surgery. In this study, the authors present a large series of patients with vascular or oncological entities, in which they used indocyanine green videoangiography (ICG-VA) with FLOW 800 analysis to study the patient-specific venous flow characteristics and the management workflow in cases in which a venous sacrifice was necessary...

PURPOSE: Probe-based confocal laser endomicroscopy (pCLE) enables in vivo, in situ tissue characterisation without changes in the surgical setting and simplifies the oncological surgical workflow. The potential of this technique in identifying residual cancer tissue and improving resection rates of brain tumours has been recently verified in pilot studies. The interpretation of endomicroscopic information is challenging, particularly for surgeons who do not themselves routinely review histopathology...

Purpose: Almost half of all patients diagnosed with non-small cell lung cancer (NSCLC) have distant metastases at presentation. One-third of patients with NSCLC will have brain metastases. Without effective treatment, the median survival is only 1 month. However, it is difficult to treat brain metastases with systemic chemotherapy since the agents have difficulty crossing the blood-brain barrier. Therefore, it is important to estimate the patient's survival prognosis. The aim of this study was to analyze prognostic factors for survival in Turkish patients who received chemotherapy after cranial irradiation for NSCLC with brain metastases...

BACKGROUND AND IMPORTANCE: Mesencephalic tectal gliomas represent a subset of midbrain tumors, which are more frequent in children than in adults. They usually become symptomatic when causing hydrocephalus by occluding the aqueduct. Because of their slow progression, due to their benign histology, they are characterized by a relatively good prognosis, although hydrocephalus might jeopardize patients' prognosis. Treatment is usually represented by cerebrospinal fluid diversion associated or not with biopsy...

This study presents a unique series of malignant supratentorial gliomas in children previously cured from non-CNS primary cancer. On neuroimaging these tumors were not specific, so the patients were suspected of cerebral recurrence of their primary neoplasm: leukemia in four children and sarcoma in one child. Histologically, the group contained four glioblastomas and one anaplastic astrocytoma. Three patients underwent neurosurgical resection, while the other two underwent stereotactic diagnostic biopsy only...

Intraoperative neurosurgical histopathologic diagnoses rely on evaluation of rapid tissue preparations such as frozen sections and smears with conventional light microscopy. Although useful, these techniques are time consuming and therefore cannot provide real-time intraoperative feedback. In vivo molecular imaging techniques are emerging as novel methods for generating real-time diagnostic histopathologic images of tumors and their surrounding tissues. These imaging techniques rely on contrast generated by exogenous fluorescent dyes, autofluorescence of endogenous molecules, fluorescence decay of excited molecules, or light scattering...
