Abstract
OBJECTIVE Seizures are common and significantly disabling for patients with brain metastases (BMs). Although resection can provide seizure control, a subset of patients with BMs may continue to suffer seizures postoperatively. Genomic BM characteristics may influence which patients are at risk for postoperative seizures. This work explores correlations between genomic alterations and risk of postoperative seizures following BM resection. METHODS All patients underwent BM resection at a single institution, with available clinical and sequencing data on more than 500 oncogenes. Clinical seizures were documented pre- and postoperatively. A random forest machine learning classification was used to determine candidate genomic alterations associated with postoperative seizures, and clinical and top genomic variables were correlated with postoperative seizures by using Cox proportional hazards models. RESULTS There were 112 patients with BMs who underwent 114 surgeries and had at least 1 month of postoperative follow-up. Seizures occurred preoperatively in 26 (22.8%) patients and postoperatively in 25 (21.9%). The Engel classification achieved at 6 months for those with preoperative seizures was class I in 13 (50%); class II in 6 (23.1%); class III in 5 (19.2%), and class IV in 2 (7.7%). In those with postoperative seizures, only 8 (32.0%) had seizures preoperatively, and preoperative seizures were not a significant predictor of postoperative seizures (HR 1.84; 95% CI 0.79-4.37; p = 0.156). On random forest classification and multivariate Cox analysis controlling for factors including recurrence, extent of resection, and number of BMs, CDKN2A alterations were associated with postoperative seizures (HR 3.22; 95% CI 1.27-8.16; p = 0.014). Melanoma BMs were associated with higher risk of postoperative seizures compared with all other primary malignancies (HR 5.23; 95% CI 1.37-19.98; p = 0.016). Of 39 BMs with CDKN2A alteration, 35.9% (14/39) had postoperative seizures, compared to 14.7% (11/75) without CDKN2A alteration. The overall rate of postoperative seizures in melanoma BMs was 42.9% (15/35), compared with 12.7% (10/79) for all other primary malignancies. CONCLUSIONS CDKN2A alterations and melanoma primary malignancy are associated with increased postoperative seizure risk following resection of BMs. These results may help guide postoperative seizure prophylaxis in patients undergoing resection of BMs.

Abstract
Seizures are among the most common clinical signs in people with glioblastoma. Advances over the past 5 years, including new clinical trial data, have increased the understanding of why some individuals with glioblastoma are susceptible to seizures, how seizures manifest clinically, and what implications seizures have for patient management. The pathophysiology of epilepsy in people with glioblastoma relates to a combination of intrinsic epileptogenicity of tumour tissue, alterations in the tumour and peritumoural microenvironment, and the physical and functional disturbance of adjacent brain structures. Successful management of epilepsy in people with glioblastoma remains challenging; factors such as drug-drug interactions between cancer therapies and antiseizure medications, and medication side-effects, can affect seizure outcomes and quality of life. Advances in novel therapies provide some promise for people with glioblastoma; however, the effects of these therapies on seizures are yet to be fully determined. Looking forward, insights into electrical activity as a driver of tumour cell growth and the intrinsic hyperexcitability of tumour tissue might represent useful targets for treatment and disease modification. There is a pressing need for large randomised clinical trials in this field.

Abstract
Objectives The study aims to correlate craniotomies and their effect on epileptic activity and to assess the impact of prophylaxis anti-epileptic drugs (AEDs) used to prevent seizure activity after craniotomy. Method This was a mono-center retrospective review of patients undergoing craniotomy from 2010-2021 at King Abdulaziz University Hospital (KAUH), a tertiary center in Jeddah, Saudi Arabia. The patients were divided into two groups depending on preoperative anti-epileptic drug usage and the occurrence of seizures after the surgery. Out of 192, 24.6% had a seizure before the surgery, while the rest reported no seizure activity. We used descriptive statistics to categorize the study population and applied t-test and chi-square to compare different groups and outcomes. Results One-hundred-ninety-two patients were studied: 24.6% had preoperative seizure history and 82.1% were on prophylactic AEDs. The incidence of post-craniotomy seizures was 7.6% in patients with anti-epileptic prophylaxis and 2.7% in those without prophylaxis before the surgery. Almost three-quarters of the patients (72.4%) had surgery for brain tumor resection and redo-craniotomy while the rest (25.5%) were for intracranial hemorrhages (p=0.052). On multivariate analysis, the primary predictor of post-craniotomy seizures was the preoperative history of seizures. Finally, the administration of AEDs does not prevent seizure occurrence after craniotomy (p=0.153). Moreover, the type of prophylaxis and reason for the surgery played no significant role in seizure occurrence. Conclusion Post-craniotomy seizures were common, and preoperative AEDs for primary seizure prevention were not associated with a lower incidence of seizures after craniotomy.

Abstract
ABTRACT BACKGROUND Status epilepticus (SE) is characterized by continuous course of clinical and/or electrographic epileptic seizures. There are little data on the course and outcomes of SE after resection of brain tumors. OBJECTIVE To analyze clinical and electrographic manifestations of SE, its course and outcomes in short-term period after resection of brain tumors. MATERIAL AND METHODS We analyzed medical records of 18 patients over 18 years old between 2012 and 2019. All patients underwent resection of brain tumor and developed SE after surgery. Clinical criteria were repeated epileptic seizures without interictal recovery of consciousness, stereotypical motor phenomena, impaired consciousness with continued epileptic activity according to video-EEG data. We analyzed EEG data, neurological status, CT and laboratory data. RESULTS Metastases (33%) and meningiomas (16%) prevailed. Supratentorial tumors were observed in 61% of patients. Two patients had preoperative seizures. Non-convulsive SE was diagnosed in 62% of patients. SE was successfully treated in 77% of cases. Mortality rate in patients with SE was 44%. CONCLUSION Early postoperative SE is rare after brain tumor surgery (about 0.09%). Nevertheless, this complication is associated with high mortality. Non-convulsive SE is common (62%) that should be considered in postoperative management.

Abstract
Introduction: Resection of intra-axial tumors (IaT) in eloquent brain regions risks major postoperative neurological deficits. Awake craniotomy is often used to navigate these areas; however, some patients are ineligible for awake procedures. The trans-sulcal approach (TScal) was introduced to reduce parenchymal trauma during tumor resection. We report our experiences utilizing TScal for resection of deep IaT located in eloquent areas. Materials and Methods: This is a single-center retrospective analysis of patients who underwent IaT resection in eloquent areas via TScal from January 2013 to April 2021. Seventeen cases were reviewed, and relevant data was collected. Fluorescence-guided surgery with 5-aminolevulinic acid (ALA) and intraoperative ultrasound was performed in some cases. Results: Seventeen patients (10 males, 7 females) averaging 61.2 years-old (range, 21-76) were included in this study. Average length of stay was 4.8 days, and only 2 patients (11.8%) required hospital readmission within 30 days. Gross total resection (GTR) was achieved in 15 patients (88.2%), while subtotal resection occurred in 2 patients (11.8%). Eleven patients (64.7%) reported full resolution of symptoms, 4 patients (23.5%) reported deficit improvement, and 2 patients (11.8%) experienced no change from their preoperative deficits. No patient developed new permanent deficits postoperatively. Discussion: GTR, preoperative deficit reduction, and complications were comparable to awake craniotomy and other TScal studies. Ancillary intraoperative techniques, such as brain mapping, 5-ALA and intraoperative ultrasound, are afforded by TScal to improve resection rates and overall outcomes. Conclusions: TScal can be an option for patients with deep lesions in eloquent areas who are not candidates for awake surgeries.

Cho HJ, Olson S. The use of prophylactic antiepileptic medication and driving restrictions for craniotomies among Australian and New Zealand neurosurgeons. J Clin Neurosci 2022; 103:112-118.

Abstract
Prophylactic antiepileptic drug (pAED) use for craniotomy surgery is currently not supported in literature [1-5] except possibly in traumatic brain injury (TBI) [6]. Post craniotomy driving restrictions using the Austroad guidelines are based upon literature on TBI and not specifically craniotomy [16-18]. This study was to review Australian and New Zealand neurosurgeons on their use of pAED and advice on driving restrictions post craniotomy surgery. A voluntary and anonymous survey link was distributed to the members of the Neurosurgical Society of Australasia (NSA) through the NSA newsletter. The survey was available on the SurveyMonkey platform in the year 2021 August to December. Questions regarding the use of pAED and duration of driving restrictions were presented to survey participants. Sixty-one (26 %) out of 231 neurosurgeons responded to the survey. Thirty-six percent of respondents stated that they prescribed pAEDs regularly whilst thirty-two percent of respondents did not routinely prescribe pAEDs for craniotomy surgery. Driving restrictions varied but the most common driving restriction post craniotomy surgery was 6 months. There were divided opinions among NSA members in regards to pAED use and driving restrictions. The rationale for pAED use and prolonged driving restrictions for craniotomy surgery needs to be re-evaluated with current literature. The significant effect this may have on the well-being and quality life of patients need to be considered before prescribing pAEDs or long driving restrictions.

Abstract
Background Brain tumor patients tend to develop postoperative epileptic seizures, which can lead to an unfavorable outcome. Although the incidence of postoperative epileptic seizures and adverse events are improved with the advent of levetiracetam (LEV), postoperative epilepsy occurs at a frequency of 4.6% or higher. In brain tumor patients, the addition of sodium channel blockers (SCBs) to LEV significantly reduces seizures, though confirmed in a non-postoperative study. Thus, the combination of SCBs with LEV might be promising. Objective In this prospective randomized controlled trial we investigated the safety, evaluated by adverse events during one and two weeks after surgery, and the efficacy, evaluated by the incidence of early epilepsy, including non-convulsive status epilepticus (NCSE), of using LEV alone or SCBs added to LEV in patients who underwent craniotomy or biopsy for brain tumors or brain mass lesions. Methods Patients with brain tumors or brain mass lesions undergoing surgical interventions, excluding endoscopic endonasal surgery (EES), with a diagnosis of epilepsy were eligible for this study. Patients are randomized into either Group A or B (B1 or B2) after the informed consents are taken; LEV alone in Group A patients, while LEV and SCBs in Group B patients (GroupB1, intravenous fosphenytoin plus oral lacosamide (LCM) and GroupB2, intravenous LCM plus oral LCM) were administered postoperatively. Fifty-three patients were enrolled during the first two and a half years of the study and four of them were excluded, resulting in the accumulation of 49 patients’ data. Results Postoperative epileptic seizures occurred only in three out of 49 patients during the first week (6.1%) and in seven patients within two weeks after surgery (14.3%, including the three patients during the first week). In Group A, epileptic seizures occurred in two out of 26 patients during the first week (7.7%) and in five patients within two weeks (19.2%) after surgery. In Group B, epileptic seizures occurred in one out of 23 patients during the first week (4.3%) and in two patients during the first two weeks (8.7%). Low complication grade of epileptic seizures was observed in Group B rather than in Group A, however, without significant difference (p=0.256). There was no difference in the frequency of adverse effects in each group. Conclusion Although not statistically significant, the incidence of epileptic seizures within one week after surgery was lesser in LEV+SCBs groups than in LEV alone. No hepatic damage or renal function worsening occurred with the addition of LCM, suggesting the safety of LEV+SCBs therapy.

An integrated risk model stratifying seizure risk following brain tumor resection among seizure-naive patients without antiepileptic prophylaxis. Neurosurg Focus 2022; 52:E3.

Abstract
OBJECTIVE
The natural history of seizure risk after brain tumor resection is not well understood. Identifying seizure-naive patients at highest risk for postoperative seizure events remains a clinical need. In this study, the authors sought to develop a predictive modeling strategy for anticipating postcraniotomy seizures after brain tumor resection.
METHODS
The IBM Watson Health MarketScan Claims Database was canvassed for antiepileptic drug (AED)– and seizure-naive patients who underwent brain tumor resection (2007–2016). The primary event of interest was short-term seizure risk (within 90 days postdischarge). The secondary event of interest was long-term seizure risk during the follow-up period. To model early-onset and long-term postdischarge seizure risk, a penalized logistic regression classifier and multivariable Cox regression model, respectively, were built, which integrated patient-, tumor-, and hospitalization-specific features. To compare empirical seizure rates, equally sized cohort tertiles were created and labeled as low risk, medium risk, and high risk.
RESULTS
Of 5470 patients, 983 (18.0%) had a postdischarge-coded seizure event. The integrated binary classification approach for predicting early-onset seizures outperformed models using feature subsets (area under the curve [AUC] = 0.751, hospitalization features only AUC = 0.667, patient features only AUC = 0.603, and tumor features only AUC = 0.694). Held-out validation patient cases that were predicted by the integrated model to have elevated short-term risk more frequently developed seizures within 90 days of discharge (24.1% high risk vs 3.8% low risk, p < 0.001). Compared with those in the low-risk tertile by the long-term seizure risk model, patients in the medium-risk and high-risk tertiles had 2.13 (95% CI 1.45–3.11) and 6.24 (95% CI 4.40–8.84) times higher long-term risk for postdischarge seizures. Only patients predicted as high risk developed status epilepticus within 90 days of discharge (1.7% high risk vs 0% low risk, p = 0.003).
CONCLUSIONS
The authors have presented a risk-stratified model that accurately predicted short- and long-term seizure risk in patients who underwent brain tumor resection, which may be used to stratify future study of postoperative AED prophylaxis in highest-risk patient subpopulations.

Abstract
PURPOSE This study aim to identify the clinical risk factors of and to develop a radiomics-based predictive model for early postoperative seizure. METHODS We retrospectively assessed 322 operative patients with meningioma who met the inclusion criteria from January 2014 to December 2016 at The First Affiliated Hospital of Wenzhou Medical University. Univariate and multivariate analyses were performed to determine the predictive value of clinical variables. Magnetic resonance imaging (MRI) was performed to obtain the radiomic score (Rscore) for early postoperative seizure. Radiological features were evaluated using the AK software. The minimal redundancy (mRMR) and least absolute shrinkage and selection operator (LASSO) methods were used to assess for radiomic features, and the Rscore was obtained based on radiomic characteristics using a specific formula. RESULTS In total, 260 patients who met the inclusion criteria were finally enrolled in this study. Among them, 20 experienced early postoperative seizure. Logistic regression analysis showed that Rscore was associated with a significantly high risk of seizure (p<0.000). Receiver operating characteristic (ROC) curve analysis revealed that the area under the ROC curve of the Rscore was 0.92 (95% confidence interval: 0.853-0.987). The model had a high accuracy for predicting early postoperative seizure. CONCLUSIONS The Rscore was found to be associated with a high risk of early postoperative seizures. Thus, a higher Rscore (>-1.644) can identify high-risk patients requiring intensive care.

Abstract
Interest in the use of pharmacological ascorbate as a treatment for cancer has increased considerably since it was introduced by Cameron and Pauling in the 1970s. Recently, pharmacological ascorbate has been used in preclinical and early-phase clinical trials as a selective radiation sensitizer in cancer. The results of these studies are promising. This review summarizes data on pharmacological ascorbate (1) as a safe and efficacious adjuvant to cancer therapy; (2) as a selective radiosensitizer of cancer via a mechanism involving hydrogen peroxide; and (3) as a radioprotector in normal tissues. Additionally, we present new data demonstrating the ability of pharmacological ascorbate to enhance radiation-induced DNA damage in glioblastoma cells, facilitating cancer cell death. We propose that pharmacological ascorbate may be a general radiosensitizer in cancer therapy and simultaneously a radioprotector of normal tissue.

Abstract
OBJECTIVE To update the 2000 American Academy of Neurology (AAN) practice parameter on anticonvulsant prophylaxis in patients with newly diagnosed brain tumors. METHODS Following the 2017 AAN methodologies, a systematic literature review utilizing PubMed, EMBASE, Cochrane, and Web of Science databases was performed. The studies were rated based on the AAN therapeutic or causation classification of evidence (Class I-IV). RESULTS Thirty-seven articles were selected for final analysis. There were limited high level, Class I studies and mostly Class II and III studies. The AAN affirmed the value of these guidelines. RECOMMENDATIONS In patients with newly diagnosed brain tumors who have not had a seizure, clinicians should not prescribe anti-epileptic drugs (AEDs) to reduce the risk of seizures (Level A). In brain tumor patients undergoing surgery, there is insufficient evidence to recommend prescribing AEDs to reduce the risk of seizures in the peri- or postoperative period (Level C). There is insufficient evidence to support prescribing valproic acid or levetiracetam with the intent to prolong progression-free or overall survival (Level C). Physicians may consider use of levetiracetam over older AEDs to reduce side effects (Level C). There is insufficient evidence to support using tumor location, histology, grade, molecular/imaging features, when deciding whether or not to prescribe prophylactic AEDs (Level U).

Abstract
Abstract
Background Cranial surgery is associated with multiple postoperative complications varying from simple nausea and vomiting to devastating complications such as stroke and death. This multicentre collaborative effort was envisioned to collect observational data regarding postoperative complications in cranial surgeries among the Indian population. The aim of this study was to describe the postoperative neurological complications occurring within the first 24 hours after surgery and to identify the predictive factors.
Methods Data was collected from three participating tertiary care academic institutions. The study was prospective, observational, multicentre design with data collected over a period of two months or 100 cases, whichever is earlier, from each participating institute. A predesigned Microsoft excel sheet was distributed among all three centers to maintain uniformity. All patients aged 18 years and above of both sexes undergoing elective or emergency craniotomies were included in the study. The postoperative neurological complications (within 24 hours) assessed were: (1) Neurological deficit (ND) defined as new focal neurological motor deficit relative to preoperative status. (2) Sensorium deterioration (SD) defined as reduction in Glasgow coma score (GCS) by 2 or more points compared with preoperative GCS. (4) Postoperative seizures (SZs) defined as any seizure activity. All possible variables associated with the above neurological complications were tested using Chi-square/Fisher exact test or Mann–Whitney U test. The predictors, which were statistically significant at p < 0.2, were entered into a multiple logistic regression model. Alpha error of 5% was taken as significant.
Results Data from three institutions was collected with a total of 279 cases. In total, there were 53 (19%) neurological complications. There were 28 patients with new postoperative NDs (10.04%), 24 patients had SD (8.6%), and 17 patients had seizures (6.1%). Neurological deficits were significantly less in institution 2. Diagnosis of traumatic brain injury (TBI) was associated with very low risk of ND, and vascular pathology was associated with higher chance of a ND. The duration of anesthesia was found to be significantly predictive of SD (OR/CI = 1.01 / 1–1.02). None of the factors were predictive of PS.
Conclusion The incidences of postoperative ND, SD and postoperative seizures were 10%, 8.6%, and 6.1%, respectively. Studies with a much larger sample size are required for a better and detailed analysis of these complications.

Biomarkers of Seizure Activity in Patients With Intracranial Metastases and Gliomas: A Wide Range Study of Correlated Regions of Interest. Front Neurol 2020; 11:444. [PMID: 32547475 PMCID: PMC7273506 DOI: 10.3389/fneur.2020.00444] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2019] [Accepted: 04/27/2020] [Indexed: 11/29/2022] Open
Abstract
Introduction: Studies quantifying cortical metrics in brain tumor patients who present with seizures are limited. The current investigation assesses morphometric/volumetric differences across a wide range of anatomical regions, including temporal and extra-temporal, in patients with gliomas and intracranial metastases (IMs) presenting with seizures that could serve as a biomarker in the identification of seizure expression and serve as a neuronal target for mitigation. Methods: In a retrospective design, the MR sequences of ninety-two tumor patients [55% gliomas; 45% IM] and 34 controls were subjected to sophisticated morphometric and volumetric assessments using BrainSuite and MATLAB modules. We examined 103 regions of interests (ROIs) across eight distinct cortical categories of interests (COI) [gray matter, white matter; total volume, CSF; cortical areas: inner, mid, pial; cortical thickness]. The primary endpoint was quantifying and identifying ROIs with significant differences in z-scores based upon the presence of seizures. Feature selection employing neighborhood component analysis (NCA) determined the ROI within each COI having the highest significance/weight in the differentiation of seizure vs. non-seizure patients harboring brain tumor. Results: Overall, the mean age of the cohort was 58.0 ± 12.8 years, and 45% were women. The prevalence of seizures in tumor patients was 28%. Forty-two ROIs across the eight pre-defined COIs had significant differences in z-scores between tumor patients presenting with and without seizures. The NCA feature selection noted the volume of pars-orbitalis and right middle temporal gyrus to have the highest weight in differentiating tumor patients based on seizures for three distinct COIs [GM, total volume, and CSF volume] and white matter, respectively. Left-sided transverse temporal gyrus, left precuneus, left transverse temporal, and left supramarginal gyrus were associated with having the highest weight in the differentiation of seizure vs. non-seizure in tumor patients for morphometrics relating to cortical areas in the pial, inner and mid regions and cortical thickness, respectively. Conclusion: Our study elucidates potential biomarkers for seizure targeting in patients with gliomas and IMs based upon morphometric and volumetric assessments. Amongst the widespread brain regions examined in our cohort, pars orbitalis, supramarginal and temporal gyrus (middle, transverse), and the pre-cuneus contribute a maximal potential for differentiation of seizure patients from non-seizure.

Abstract
INTRODUCTION It is common practice to prescribe prophylactic antiepileptic drugs (AED) to high-grade glioma (HGG) patients without a history of seizures, yet with limited evidence supporting its use. Ideally, the effectiveness of prophylactic anticonvulsants must outweigh the occurrence of adverse effects and interactions related to AED. The authors conducted a systematic review and metanalysis of longitudinal studies regarding the effectiveness of prophylactic AED in seizure-naïve HGG patients. MATERIALS AND METHODS PubMed/MEDLINE, Cochrane Central Register of Controlled trials, Embase and clinicaltrials.gov databases were systematically searched. Of the initial 1773 studies identified, 15 were finally selected for data extraction and analysis. Heterogeneity among studies, pooled hazard ratios, publication bias and sensitivity analyses were performed separately for a 15-study group (HGG patients within larger series of brain tumors) and a 6-study group (exclusively HGG patients). RESULTS AED prophylaxis did not significantly reduce the incidence of postoperative seizures compared with controls, both in the 15-study group (Mantel-Haenszel random-effects pooled OR 1.08, 95% CI 0.82-1.43, 2123 patients) and in the 6-study group (pooled OR 1.22, 95% CI 0.77-1.92, 540 patients). However, some issues (paucity of prospective trials, overall moderate-risk of bias, and few studies addressing HGG patients exclusively) preclude firm conclusions against routine prophylactic AED prescription. Reported adverse effects attributable to AED were acceptable in the majority of studies. CONCLUSIONS Within the limitations of this review, the results of this metanalysis do not support the routine administration of prophylactic AED to HGG patients without a history of seizures.

Abstract
OBJECTIVEDe novo seizure following craniotomy (DSC) for nontraumatic pathology may adversely affect medical and neurological outcomes in patients with no history of seizures who have undergone craniotomies. Antiepileptic drugs (AEDs) are commonly used prophylactically in patients undergoing craniotomy; however, evidence supporting this practice is limited and mixed. The authors aimed to collate the available evidence on the efficacy and tolerability of levetiracetam monotherapy and compare it with that of the classic AED, phenytoin, for DSC.METHODSPubMed, Embase, Web of Science, and the Cochrane Library were searched for studies that compared levetiracetam with phenytoin for DSC prevention. Inclusion criteria were adult patients with no history of epilepsy who underwent craniotomy with prophylactic usage of phenytoin, a comparator group with levetiracetam treatment as the main treatment difference between the two groups, and availability of data on the numbers of patients and seizures for each group. Patients with brain injury and previous seizure history were excluded. DSC occurrence and adverse drug reaction (ADR) were evaluated. Seizure occurrence was calculated using the Peto odds ratio (POR), which is the relative effect estimation method of choice for binary data with rare events.RESULTSData from 7 studies involving 803 patients were included. The DSC occurrence rate was 1.26% (4/318) in the levetiracetam cohort and 6.60% (32/485) in the phenytoin cohort. Meta-analysis showed that levetiracetam is significantly superior to phenytoin for DSC prevention (POR 0.233, 95% confidence interval [CI] 0.117-0.462, p < 0.001). Subgroup analysis demonstrated that levetiracetam is superior to phenytoin for DSC due to all brain diseases (POR 0.129, 95% CI 0.039-0.423, p = 0.001) and tumor (POR 0.282, 95% CI 0.117-0.678, p = 0.005). ADRs in the levetiracetam group were cognitive disturbance, thrombophlebitis, irritability, lethargy, tiredness, and asthenia, whereas rash, anaphylaxis, arrhythmia, and hyponatremia were more common in the phenytoin group. The overall occurrence of ADR in the phenytoin (34/466) and levetiracetam (26/432) groups (p = 0.44) demonstrated no statistically significant difference in ADR occurrence. However, the discontinuation rate of AEDs due to ADR was 53/297 in the phenytoin group and 6/196 in the levetiracetam group (POR 0.266, 95% CI 0.137-0.518, p < 0.001).CONCLUSIONSLevetiracetam is superior to phenytoin for DSC prevention for nontraumatic pathology and has fewer serious ADRs that lead to discontinuation. Further high-quality studies that compare levetiracetam with placebo are necessary to provide evidence for establishing AED guidelines.

Prophylactic antiepileptic treatment with levetiracetam for patients undergoing supratentorial brain tumor surgery: a two-center matched cohort study. Neurosurg Rev 2019; 43:709-718.

Abstract
Guidelines on the administration of prophylactic antiepileptic drugs (AED), and specifically levetiracetam, for brain tumor surgery are still lacking. In this two-center matched cohort study, we aim to compare the proportion of postoperative seizures during follow-up after supratentorial tumor surgery in patients receiving no seizure prophylaxis, and those treated with levetiracetam perioperatively. Three hundred sixteen consecutive patients undergoing supratentorial tumor surgery, without history of seizures were included: 207 patients did not receive AED (no AED group), and 109 patients received levetiracetam perioperatively (levetiracetam group). The primary outcome measure was the rate of postoperative seizures. Additionally, uni- and multivariate analyses assessing possible risk factors for postoperative seizures were performed. No statistically significant difference for the occurrence of postoperative seizures was found between the two groups (10.1%, n = 21 in the no AED group vs. 9.2%, n = 10, in the levetiracetam group; p = 0.69, OR 0.9 [0.4-2.0), NNT 103 [12.9-17.1]). After propensity score matching, the primary outcome was observed in 13 patients (12.4%) from the no AED group and in 9 patients (8.6%) from the levetiracetam group (p = 0.50, OR 0.7 [0.3-1.6], NNT 26.3 [8.3-22.4]). Among all analyzed possible risk factors for postoperative seizures, only postoperative infarction showed a statistically significant association with higher seizure rates in multivariate analysis (OR 8.2 [1.1-60.6], p = 0.04). Prophylactic treatment with levetiracetam after brain tumor surgery showed no statistically significant effect in preventing postoperative seizures. However, in case a postoperative infarction occurs, its administration might be indicated.

Abstract
BACKGROUND Stereotactic radiosurgery (SRS) is indicated for a spectrum of brain tumors and is often an outpatient procedure, though severe disease may precipitate inpatient treatment. Readmission following inpatient SRS for brain tumors is not well understood. OBJECTIVES To characterize rate, associative factors, and predictors of SRS readmission. METHODS Retrospective analysis of inpatients treated with SRS for brain neoplasms was conducted (2010-2014 Nationwide Readmissions Database). Diagnoses upon readmission were characterized. Associations with 30-day readmission were identified using multivariate analyses. RESULTS Of 2,553 patients undergoing SRS, 390 were readmitted (15.3%) within 30 days. Leading readmission diagnoses were infectious or embolic. Neurological readmissions of intracerebral hemorrhage (2.1%) and cerebral edema (1.5%) were rare. Malignant tumors (OR=1.60, p=0.007) and discharge to facility (OR=1.41, p=0.004) were associated with readmission. CONCLUSION Inpatients receiving SRS for brain tumors have a 15.3% 30-day readmission rate. Neurologic readmissions were rare, underscoring the neurological safety of SRS, even in sick inpatients.
