Glioblastoma multiforme (GBM), WHO grade IV astrocytoma, is the most common primary neoplasm of the central nervous system (CNS) and has the highest malignancy and mortality rates. The invasive nature of GBM complicates surgical resection and restricts chemotherapeutic access, contributing to poor patient prognosis. The migration of tumor cells is closely related to the tumor cell proliferation. The acquisition of migratory capability, in addition to intracellular factors, is proposed to be a crucial mechanism during the progression of invasion...

BACKGROUND: Different surgical approaches have been developed for dealing with third ventricle lesions, all aimed at obtaining a safe removal minimizing brain manipulation. The supraorbital subfrontal trans-lamina terminalis route, commonly employed only for the anterior third ventricle, could represent, in selected cases with endoscopic assistance, an alternative approach to posterior third ventricular lesions. METHODS: Seven patients underwent a supraorbital subfrontal trans-laminar endoscope-assisted approach to posterior third ventricle tumors (two craniopharyngiomas, one papillary tumor of the pineal region, one pineocytoma, two neurocytomas, one glioblastoma)...

INTRODUCTION: Glioblastoma multiforme is the most frequent malignant tumour of the central nervous system, and its incidence reaches 80% in those over 50 years of age. Life expectancy has increased in the population in recent times and an analysis of the post-surgical complications affecting elderly patients is of great importance for a correct surgical indication. AIMS: To analyse the factors related with post-surgical complications in elderly patients. PATIENTS AND METHODS: A sample of 88 patients diagnosed with glioblastoma multiforme between 31 and 78 years of age was analysed retrospectively...

PURPOSE: We assessed agreement among neurosurgeons on surgical approaches to individual glioblastoma patients and between their approach and those recommended by the topographical staging system described by Shinoda. METHODS: Five neurosurgeons were provided with pre-surgical MRIs of 76 patients. They selected the surgical approach [biopsy, partial resection, or gross total resection (GTR)] that they would recommend for each patient. They were blinded to each other's response and they were told that patients were younger than 50 years old and without symptoms...

OBJECTIVE Laser interstitial thermal therapy (LITT), sometimes referred to as "stereotactic laser ablation," has demonstrated utility in a subset of high-risk surgical patients with difficult to access (DTA) intracranial neoplasms. However, the treatment of tumors larger than 10 cm(3) is associated with suboptimal outcomes and morbidity. This may limit the utility of LITT in dealing with precisely those large or deep tumors that are most difficult to treat with conventional approaches. Recently, several groups have reported on minimally invasive transsulcal approaches utilizing tubular retracting systems...

BACKGROUND: Glioblastoma (GBM) is the most common and aggressive malignant brain tumor in adults. Current treatment options at diagnosis are multimodal and include surgical resection, radiation, and chemotherapy. Significant advances in the understanding of the molecular pathology of GBM and associated cell signaling pathways have opened opportunities for new therapies for recurrent and newly diagnosed disease. Innovative treatments, such as tumor-treating fields (TTFields) and immunotherapy, give hope for enhanced survival...

BACKGROUND: The management of gliomas is based on precise histologic diagnosis. The tumor tissue can be obtained during open surgery or via stereotactic biopsy. Intraoperative tissue imaging could substantially improve biopsy precision and, ultimately, the extent of resection. OBJECTIVE: To show the feasibility of intraoperative in vivo probe-based confocal laser endomicroscopy (pCLE) in surgery and biopsy of gliomas. METHODS: In our prospective observational study, 9 adult patients were enrolled between September 2014 and January 2015...

BACKGROUND: The pathogenesis of glioblastoma is complex, and the implicated molecular mechanisms are yet to be understood. There are scattered reports describing a possible relationship between meningioma and glioblastoma and more rarely a relationship between infarction and glioblastoma. CASE PRESENTATION: We are reporting a 32-year-old male who developed left middle cerebral artery (MCA) infarction as a surgical complication for sphenoid meningioma. He developed recurrent symptoms 4 months later due to development of a glioblastoma adjacent to both the territory of the prior MCA infarct and the residual meningioma...

An 8-year-old boy suffering from progressive glioblastoma was scheduled for neurosurgery. Prior to induction of anaesthesia pulse oximetry measured 64 % saturation of oxygen (SpO2). Arterial blood gas analysis revealed normal oxygen saturation and normal oxygen partial pressure. After having ruled out technical problems of pulse oximetry the neurosurgical procedure was halted. Meticulous examination of the child's history and medication did not explain a possible interaction of drugs with pulse oximetry. A Chinese herb tea had been given to the child, but was then stopped on the day of admission...

BACKGROUND: Frailty is an emerging means of assessing overall health status and guiding management for geriatric patients. Frailty is associated with outcomes for many surgical indications in this age group. While half of all glioblastoma patients are 65 years old or older, frailty has not been examined in relation to surgery for glioblastoma. METHODS: We performed a retrospective study of patients age 65 years and older with pathologically confirmed glioblastoma at Columbia Presbyterian Hospital from 2000 to 2012; 319 patients were identified, 243 of whom underwent craniotomy for lobar lesions...

BACKGROUND: In most cases, glioblastomas are associated with seizures, headaches, neurological deficits, aphasia, or bleeding. But these tumors are rarely associated with cerebral infarction and never so deadly. CASE REPORT: A 40-year-old man presented with sudden morning isolated aphasia. One hour later, he developed a motor deficit at right upper member, quickly completed with a total right hemiplegia. Imaging studies revealed a left frontotemporal enhancing glioblastoma with a perilesional edema which produced an important mass effect on the posterior arm of the external capsule, on the primary motor cortex posteriorly and the entire sylvian valley anteriorly...
