Practical guidance for direct oral anticoagulant use in the treatment of venous thromboembolism in primary and metastatic brain tumor patients.

Management of venous thromboembolism (VTE) in patients with primary and metastatic brain tumors (BT) is challenging because of the risk of intracranial hemorrhage (ICH). There are no prospective clinical trials evaluating safety and efficacy of direct oral anticoagulants (DOACs), specifically in patients with BT, but they are widely used for VTE in this population. A group of neuro-oncology experts convened to provide practical clinical guidance for the off-label use of DOACs in treating VTE in patients with BT. We searched PubMed for the following terms: BTs, glioma, glioblastoma (GBM), brain metastasis, VTE, heparin, low-molecular-weight heparin (LWMH), DOACs, and ICH. Although prospective clinical trials are needed, the recommendations presented aim to assist clinicians in making informed decisions regarding DOACs for VTE in patients with BT.

Gender, Racial, and Geographical Disparities in Malignant Brain Tumor Mortality in the USA.

INTRODUCTION: Malignant brain tumors are malignancies which are known for their low survival rates. Despite advancements in treatments in the last decade, the disparities in malignant brain cancer mortality among the US population remain unclear. METHODS: We analyzed death certificate data from the US CDC WONDER from 1999 to 2020 to determine the longitudinal trends of malignant brain tumor mortality. Malignant brain tumor (ICD-10 C71.0-71.9) was listed as the underlying cause of death. Age-adjusted mortality rates (AAMRs) per 100,000 individuals were calculated by standardizing the AAMR to the year 2000 US population. RESULTS: From 1999 to 2020, there were 306,375 deaths due to malignant brain tumors. The AAMR decreased from 5.57 (95% CI, 5.47-5.67) per 100,000 individuals in 1999 to 5.40 (95% CI, 5.31-5.48) per 100,000 individuals in 2020, with an annual percent decrease of -0.05 (95% CI, -0.22, 0.12). Whites had the highest AAMR (6.05 [95% CI, 6.02-6.07] per 100,000 individuals), followed by Hispanics (3.70 [95% CI, 3.64-3.76]) per 100,000 individuals, blacks (3.09 [95% CI, 3.04-3.14] per 100,000 individuals), American Indians (2.82 [95% CI, 2.64-3.00] per 100,000 individuals), and Asians (2.44 [95% CI, 2.38-2.50] per 100,000 individuals). The highest AAMRs were reported in the Midwest region (5.58 [95% CI, 5.54-5.62] per 100,000 individuals) and the rural regions (5.66 [95% CI, 5.61-5.71] per 100,000 individuals). CONCLUSIONS: Our study highlights the mortality disparity among different races, geographic regions, and urbanization levels. The findings underscore the importance of addressing the disparities in malignant brain tumors that existed among males, white individuals, and rural populations.

Predicting FDG-PET Images From Multi-Contrast MRI Using Deep Learning in Patients With Brain Neoplasms.

BACKGROUND: 18 F-fluorodeoxyglucose (FDG) positron emission tomography (PET) is valuable for determining presence of viable tumor, but is limited by geographical restrictions, radiation exposure, and high cost. PURPOSE: To generate diagnostic-quality PET equivalent imaging for patients with brain neoplasms by deep learning with multi-contrast MRI. STUDY TYPE: Retrospective. SUBJECTS: Patients (59 studies from 51 subjects; age 56 ± 13 years; 29 males) who underwent 18 F-FDG PET and MRI for determining recurrent brain tumor. FIELD STRENGTH/SEQUENCE: 3T; 3D GRE T1, 3D GRE T1c, 3D FSE T2-FLAIR, and 3D FSE ASL, 18 F-FDG PET imaging. ASSESSMENT: Convolutional neural networks were trained using four MRIs as inputs and acquired FDG PET images as output. The agreement between the acquired and synthesized PET was evaluated by quality metrics and Bland-Altman plots for standardized uptake value ratio. Three physicians scored image quality on a 5-point scale, with score ≥3 as high-quality. They assessed the lesions on a 5-point scale, which was binarized to analyze diagnostic consistency of the synthesized PET compared to the acquired PET. STATISTICAL TESTS: The agreement in ratings between the acquired and synthesized PET were tested with Gwet's AC and exact Bowker test of symmetry. Agreement of the readers was assessed by Gwet's AC. P = 0.05 was used as the cutoff for statistical significance. RESULTS: The synthesized PET visually resembled the acquired PET and showed significant improvement in quality metrics (+21.7% on PSNR, +22.2% on SSIM, -31.8% on RSME) compared with ASL. A total of 49.7% of the synthesized PET were considered as high-quality compared to 73.4% of the acquired PET which was statistically significant, but with distinct variability between readers. For the positive/negative lesion assessment, the synthesized PET had an accuracy of 87% but had a tendency to overcall. CONCLUSION: The proposed deep learning model has the potential of synthesizing diagnostic quality FDG PET images without the use of radiotracers. EVIDENCE LEVEL: 3 TECHNICAL EFFICACY: Stage 2.

Sodium fluorescein and 5-aminolevulinic acid fluorescence- guided biopsy in brain lesions: a systematic review and meta-analysis.

PURPOSE: Stereotactic brain biopsies are highly efficient for diagnosing intracerebral pathologies, particularly when surgical resection is infeasible. Fluorescence-based agents such as 5-aminolevulinic acid (5-ALA) and fluorescein sodium (NaFl) can enhance diagnostic accuracy and safety, improving the visualization of lesional tissues. This meta-analysis aimed to evaluate their effect on diagnostic yield and complication rates of brain biopsies. METHODS: This study adhered to Cochrane and PRISMA guidelines. We assessed studies for diagnostic yield and complication rates. Data was analyzed using a random-effects model in RStudio. Diagnostic accuracy measures such as sensitivity and predictive values were calculated based on fluorescence visibility in biopsy samples. RESULTS: Thirty-two non-randomized studies were included, comprising 947 patients, with a mean age ranging from 37 to 77 years, and a mean sample number ranging from 1 to 15 specimens. Diagnostic yields were high: 93% for NaFl and 96% for 5-ALA. Major complications occurred in 3% of procedures with both agents, while minor complications were reported in 7% and 5% with NaFl and 5-ALA respectively. The Negative-predictive-value (NPV) of 5-ALA and NaFl were 8-11% and 60-80% respectively. NaFl demonstrates higher sensitivity and specificity at 84% and 100% compared to 5-ALA's 66%. and 85% respectively. CONCLUSION: 5-ALA and NaFl provide high diagnostic yields with acceptable safety profiles in stereotactic biopsies. NaFl showed higher sensitivity and specificity. NaFl outperforms 5ALA in terms of NPV making it more efficient for small lesions near eloquent regions or major blood vessels. The significance of these findings can be further ascertained through randomized trials.

Quality of life and family functioning 12 months after diagnosis of childhood brain tumour: A longitudinal cohort study.

BACKGROUND: The wellbeing of a child with brain tumour is affected by several factors. We present the first investigation of quality of life and family functioning in a parent and child across the first 12 months after diagnosis, examining potential factors to guide the provision of psychosocial resources to families who most need them. PROCEDURE: Data were collected from parents/carers in Queensland, Australia, from 2020 to 2023. Child (parent/carer-proxy reported) and carer quality of life was assessed across three timepoints (repeated measures analysis of variance [ANOVA]) and by five potential co-variates (mixed between-within ANOVA). Family functioning was assessed across two timepoints (repeated-measures t-test), and by potential co-variates (repeated measures ANOVA). Univariate relationships were explored with Pearson's correlation coefficient; significant relationships were entered into multiple regression models. RESULTS: Ninety-six diverse families were represented. Quality of life (child, carer) and family functioning did not change across time. Children from households with lower income reported worse cognitive difficulties (p = .023) and pain and hurt (p = .013) than those from a higher income. Caregiver quality of life was poorer for those whose child had received chemotherapy and/or radiation, was aged less than 4 years at diagnosis, and had a lower household income. At 12 months, caregiver quality of life was correlated with family functioning (r = -.45, p < .001), with positive adaptation being a significant key predictor (beta = -.66, p < .005). CONCLUSIONS: The following factors indicate a need for increased early psychosocial support: cognitive difficulties, aged <4 years at diagnosis, receiving chemotherapy and/or radiation, and low household income.

The interaction of family functioning and disease- and treatment-related factors on quality of life for children after cancer.

PURPOSE: Children with cancer experience low quality of life (QOL), yet heterogeneity underscores a need to understand how risk and resilience factors interact. This study evaluated if family functioning relates to QOL differentially depending on diagnosis and treatment intensity. METHODS: Participants included children (ages 8-14) who completed treatment within six months for either brain tumor (BT; n = 42) or non-central nervous system solid tumor (ST; n = 29). Caregivers and children rated QOL and family functioning. Treatment intensity was categorized as low, moderate, or high. Cross-informant moderation models tested hypothesized interactions. RESULTS: Child-reported family functioning significantly interacted with diagnosis and treatment intensity in models of caregiver-reported QOL. More maladaptive family functioning was associated with reduced QOL for children with BT and moderately-intense treatments. CONCLUSIONS: Children with BT and moderate treatment intensities are sensitive to family functioning, highlighting an at-risk group to target for family-level intervention. Future work should evaluate these associations longitudinally.

A fast transition: A case study of patients' experiences during the diagnostic and surgical treatment phase of an accelerated brain cancer pathway.

BACKGROUND: Patients receiving a brain cancer diagnosis may face cognitive decline and a poor prognosis. In addition, they suffer from a high symptom burden in a complex cancer pathway. The aim of this study was to investigate the early hospital experiences of brain tumour patients during the diagnostic and surgical treatment phase. METHODS: A descriptive longitudinal single-case study design was used, and data were analysed via systematic text condensation. RESULTS: The patients' experiences of being diagnosed with and treated for brain cancer were interpreted in terms of the central theme: a fast transition into an unknown journey. This theme consisted of the following subthemes: emotionally overwhelmed, putting life on hold and an unfamiliar dependency. CONCLUSIONS: Patients diagnosed with brain cancer struggle with overwhelming emotions due to this sudden life-threatening diagnosis, their fear of brain surgery and their progressing dependence. Patients did not voice their feelings, fears or needs, so these may easily be overlooked and unmet. A proactive and continuous care approach throughout the diagnostic phase is needed to support these patients.

Evaluation of risk factors for postoperative neurologic intensive care admission after brain tumor craniotomy: A single-center longitudinal study.

Background and Aims: Perioperative variable parameters can be significant risk factors for postoperative intensive care unit (ICU) admission after elective craniotomy for intracranial neoplasm, as assessed by various scoring systems such as Cranio Score. This observational study evaluates the relationship between these factors and early postoperative neurological complications necessitating ICU admission. Material and Methods: In total, 119 patients, aged 18 years and above, of either sex, American Society of Anesthesiologists (ASA) grades I-III, scheduled for elective craniotomy and tumor excision were included. The primary objective was to evaluate the relationship between perioperative risk factors and the incidence of early postoperative complications as a means of validation of the Cranio Score. The secondary outcomes studied were 30-day postoperative morbidity/mortality and the association with patient-related risk factors. Results: Forty-five of 119 patients (37.82%) required postoperative ICU care with the mean duration of ICU stay being 1.92 ± 4.91 days. Tumor location (frontal/infratemporal region), preoperative deglutition disorder, Glasgow Coma Scale (GCS) less than 15, motor deficit, cerebellar deficit, midline shift >3 mm, mass effect, tumor size, use of blood products, lateral position, inotropic support, elevated systolic/mean arterial pressures, and duration of anesthesia/surgery were associated with a higher incidence of ICU care. Maximum (P = 0.035, AOR = 1.130) and minimum systolic arterial pressures (P = 0.022, Adjusted Odds Ratio (AOR) = 0.861) were the only independent risk factors. Cranio Score was found to be an accurate predictor of complications at a cut-off point of >10.52%. The preoperative motor deficit was the only independent risk factor associated with 30-day morbidity (AOR = 4.66). Conclusion: Perioperative hemodynamic effects are an independent predictor of postoperative ICU requirement. Further Cranio Score is shown to be a good scoring system for postoperative complications.

Primary cerebral epithelioid angiosarcoma: a case report.

BACKGROUND: Primary cerebral epithelioid angiosarcoma (PCEA) is a rare malignant tumor of the central nervous system. To the best of our knowledge, only three cases have been reported in the English language literature thus far. CASE PRESENTATION: Here, we report a fourth case in a 73-year-old man admitted for headache. Radiological examination revealed a mass in the right occipital lobe, which was removed by right occipital craniotomy. Histopathological examination revealed epithelioid angiosarcoma. The patient received radiotherapy after resection but survived for only nine months due to recurrence of the tumor and his declining further surgery. CONCLUSIONS: In this report, we add to the knowledge base on this exceedingly rare tumor, review the small number of relevant cases published previously, and analyze and summarize the clinical and pathological characteristics, treatment options and prognosis of this cancer.

Efficacy and safety of prophylaxis for venous thromboembolism in brain neoplasm patients undergoing neurosurgery: a systematic review and Bayesian network meta-analysis.

Neurosurgeons often face this dilemma. Brain neoplasm patients undergoing neurosurgery are at a high risk of venous thrombosis. However, antithrombotic drugs may induce bleeding complications. Therefore, we compared the efficacy and safety of prophylaxis for venous thromboembolism (VTE) in brain neoplasm patients undergoing neurosurgery. We searched Cochrane Central Register of Controlled Trials, Ovid MEDLINE(R), and Embase from inception to January 2022 for randomized controlled trials (RCTs) comparing the prophylactic measures efficacy and safety for VTE in brain neoplasm patients undergoing neurosurgery. The main efficacy outcome was symptomatic or asymptomatic VTE. The safety outcomes included major bleeding, minor bleeding, all occurrences of bleeding, and all-cause mortality. We used (Log) odds ratio (OR) of various chemoprophylaxis regimens to judge the safety and effectiveness of VTE. Additionally, all types of intervention were ranked by the Surface Under the Cumulative Ranking (SUCRA) value. We included 10 RCTs with 1128 brain neoplasm patients undergoing neurosurgery. For symptomatic or asymptomatic VTE and proximal DVT or PE, DOACs, compared with placebo, can significantly reduce the events. DOACs were superior to all other interventions in the rank plot of these events. For major bleeding reduction, unfractionated heparin (SUCRA value = 0.21) demonstrated better safety efficacy than others. For minor bleeding reduction, DOACs had a significantly higher risk of minor bleeding compared with placebo [Log OR 16.76, 95% CrI (1.53, 61.13)], LMWH [Log OR 15.68, 95% CrI (0.26, 60.10)] and UFH [Log OR 15.93, 95% CrI (0.22, 60.16)] respectively. Except for placebo (SUCRA values of 0.13), UFH (SUCRA values of 0.37) depicted better safety efficacy than others. For all-cause mortality, we found UFH always had significantly lower all-cause mortality compared with low-molecular-weight heparin (LMWH) [Log OR = 14.17, 95% CrI (0.05, 48.35)]. UFH plus intermittent pneumatic compression (IPC) (SUCRA value of 0.12) displayed the best safety for all-cause mortality. In our study, DOACs were more effective as prophylaxis for VTE in brain neoplasm patients undergoing neurosurgery. Regarding the safety of prophylaxis for VTE, UFH of chemoprophylaxis consistently demonstrated better safety efficacy, involving either major bleeding, minor bleeding, bleeding, or all-cause mortality.

Trigeminal Schwannoma Surgery: Challenges in Preserving Facial Sensation.

Treatments of schwannoma have dramatically improved in the previous few decades, but preservation of the functions of the originating nerve, such as facial sensation in trigeminal schwannomas, still remains challenging. As the preservation of facial sensation in trigeminal schwannomas has not been analyzed in detail, we here review our surgical experience of more than 50 trigeminal schwannoma patients, particularly focusing on their facial sensation. Since the facial sensation in each trigeminal division showed a different perioperative course even in a single patient, we investigated patient-based outcomes (average of the three divisions in each patient) and division-based outcomes separately. In the evaluation of patient-based outcomes, facial sensation remained postoperatively in 96% of all the patients, and improved in 26% and worsened in 42% of patients with preoperative hypesthesia. Posterior fossa tumors tended to most rarely disrupt facial sensation preoperatively, but were the most difficult to preserve facial sensation postoperatively. Facial pain was relieved in all six patients with preoperative neuralgia. In the division-based evaluation, facial sensation remained postoperatively in 83% of all the trigeminal divisions, and improved in 41% and worsened in 24% of the divisions with preoperative hypesthesia. The V3 region was most favorable before and after surgery, with the most frequent improvement and the least frequent functional loss. To clarify current treatment outcomes of the facial sensation and to achieve more effective preservation, standardized assessment methods of perioperative facial sensation may be required. We also introduce detailed MRI investigation methods for schwannoma, including contrast-enhanced heavily T2-weighted (CISS) imaging, arterial spin labeling (ASL), and susceptibility-weighted imaging (SWI), preoperative embolization for rare vascular-rich tumors, and modified techniques of the transpetrosal approach.

Carmustine wafer implantation for supratentorial glioblastomas, IDH-wildtype in "extreme" neurosurgical conditions.

We assessed the feasibility of Carmustine wafer implantation in "extreme" conditions (i.e. patients > 80 years and Karnofsky Performance Status score < 50) and of implantation ≥ 12 Carmustine wafers in adult patients harbouring a newly diagnosed supratentorial glioblastoma, IDH-wildtype. We performed an observational, retrospective single-centre cohort study at a tertiary surgical neuro-oncological centre between January 2006 and December 2021. Four hundred eighty patients who benefited from a surgical resection at first-line treatment were included. We showed that Carmustine wafer implantation in patients > 80 years, in patients with a Karnofsky performance status score < 50, and that implantation ≥ 12 Carmustine wafers (1) did not increase overall postoperative complication rates, (2) did not affect the completion of standard radiochemotherapy protocol, (3) did not worsen the postoperative Karnofsky Performance Status scores, and (4) did not significantly affect the time to oncological treatment. We showed that the implantation of ≥ 12 Carmustine wafers improved progression-free survival (31.0 versus 10.0 months, p = 0.025) and overall survival (39.0 versus 16.5 months, p = 0.041) without increasing postoperative complication rates. Carmustine wafer implantation during the surgical resection of a newly diagnosed supratentorial glioblastoma, IDH-wildtype is safe and efficient in patients > 80 years and in patients with preoperative Karnofsky Performance Status score < 50. The number of Carmustine wafers should be adapted (up to 16 in our experience) to the resection cavity to improve survival without increasing postoperative overall complication rates.

Early recurrence of Rosai-Doefman disease after total removal resection: a case report.

BACKGROUND: Rosai-Dorfman disease (RDD) involving the central nervous system (CNS) is rare and observed in 5% of all patients with extranodal RDD. According to a previous report, gross total resection is curative; however, we encountered a case of recurrence following gross total resection. We discuss our case and review previous reports on recurrent RDD. CASE DESCRIPTION: A 68-year-old woman came to the hospital complaining of left parietal mass. A tumor that had partially eroded the frontal bone was found. As the lesion was suspected to be malignant, we performed a total resection. Pathology results were indicative of an RDD. We did not prescribe adjuvant therapy because total resection was performed. However, after a year, abnormal accumulation in the left parietal bone was observed on FDG-PET. This was considered as recurrence, and re-excision was performed. Pathological assessments confirmed the recurrence of RDD. CONCLUSIONS: Our case demonstrated the recurrence of RDD following total resection. Future reports should assess these peculiarities. This will facilitate discussions on the risk factors and the effectiveness of treatment methods.

Multiple primary intraosseous meningioma mimicking fibrous dysplasia: a case report.

Primary intraosseous meningioma (PIM) is a rare subtype of primary extradural meningiomas. These rare ectopic meningiomas have been usually reported in the frontotemporal regions of the calvarium, orbits, and anterior cranial fossa. We report a case with bilateral tumors located in frontoparietal regions of calvarium. Our initial diagnosis was fibrous dysplasia but the lesions were seen to expand under follow-up. One was resected and the histopathological diagnosis was PIM. This is the second reported case of multiple PIM.

Changes in clinical management of diffuse IDH-mutated lower-grade gliomas: patterns of care in a 15-year period.

BACKGROUND: Isocitrate dehydrogenase (IDH) mutated diffuse lower-grade gliomas (dLGG) are infiltrating brain tumors and increasing evidence is in favor of early multimodal treatment. In a Scandinavian population-based setting, we wanted to study treatment patterns over the last 15 years, focusing on the short-term postoperative course to better understand the potential negative consequences of treatment. METHODS: Patients ≥ 18 years with primary IDH-mutated dLGG grade 2 and 3, operated between January 2007-June 2021 were identified. Patients were divided into subgroups (2007-2011, 2012-2016, and 2017-2021) and comparisons regarding tumor- and disease characteristics, treatment, and postoperative outcome were performed. RESULTS: We identified 202 patients (n = 61, 2007-2011; n = 72, 2012-2016; n = 69, 2017-2021), where of 193 underwent resection without change in proportion of resections over time. More patients underwent complete resections in recent times (6.1%; 15.7%; 26.1%, respectively; p = 0.016). Forty-two patients had any neurological deficit postoperatively (14.8%; 23.6%; 23.2%; p = 0.379), mostly minor and transient. Differences in oncological therapy were seen between the investigated subgroups. Early radiotherapy alone (32.8%; 7%; 2.9%; p < 0.001), concomitant chemoradiotherapy (23%; 37.5%; 17.4%; p = 0.022), sequential chemoradiotherapy (0%; 18%; 49.3%; p < 0.001), and no adjuvant treatment (42.6%; 23.6%; 18.8%; p = 0.009) shifted during the studied period. Increasingly more patients received proton radiotherapy compared to photon radiotherapy during the later time periods (p < 0.001). CONCLUSION: Complete resections were performed more often in later time periods without an apparent increase in surgical morbidity. Early adjuvant oncological treatment shifted towards providing chemotherapy and combined chemoradiotherapy more often in later time periods. Protons replaced photons as the radiation modality of choice.

Family functioning and adaptation following pediatric brain tumor: A systematic review.

INTRODUCTION: Pediatric brain tumor survivors (PBTS) experience psychosocial difficulties and poor quality of life (QOL). Family functioning may be adversely impacted by the stress of diagnosis and associated symptoms, which may, in turn, affect PBTS outcomes. The objective of this study was to complete a systematic review of family functioning and psychosocial outcomes in PBTS. METHODS: We conducted systematic searches of PubMed and PsychInfo. Full-text articles (n = 324) were screened and 14 were included. A risk-of-bias assessment was conducted to evaluate the quality of study conclusions. RESULTS: Studies examined associations of family functioning with adaptive, social, emotional, and behavioral outcomes, and QOL. More adaptive family functioning (cohesiveness, effective communication, lower conflict) was associated with better PBTS outcomes. Studies were limited by heterogeneous/small samples and cross-sectional designs. CONCLUSIONS: Results provide preliminary support for the relationship between family functioning and psychosocial outcomes. Common outcome measures and prospective research designs can further advance understanding.

Diagnosis and Management of Stroke in Adults with Primary Brain Tumor.

PURPOSE OF REVIEW: This article reviews the risk factors, clinical presentations, differential diagnosis, and the types of strokes frequently seen in patients with primary brain neoplasms. This includes a discussion of approaches with a review of the available literature and provides recommendations for primary and secondary prevention specific to this patient population. RECENT FINDINGS: Strokes in patients with brain tumors are often multifactorial. However, tailored approaches to stroke care are necessary to achieve optimal patient outcomes, AHA/ASA stroke guidelines provide little information on the management of stroke in cancer patients. A comprehensive algorithm for diagnosis for stroke in primary CNS tumor patients is proposed. Understanding the potential complex etiology of stroke in patients with brain tumors is essential to provide appropriate treatment and initiate optimal prevention measures early in the cancer treatment program. Optimal care therefore requires a comprehensive approach including a variety of specialists and healthcare providers.

Neuropsychological functioning in childhood cancer survivors following cranial radiotherapy - results from a long-term follow-up clinic.

Treatment of malignant childhood posterior fossa tumors (CPFT) often includes surgical resection and craniospinal radiotherapy (CSI). Nasopharyngeal tumors in childhood (CNPHT) are often treated with surgery and radiotherapy (RT), leading to incidental brain irradiation. RT to the developing brain is associated with risks for cognitive impairments. We studied cognitive functioning, health-related quality of life (HRQOL), fatigue, and psychological distress, in adult survivors of CPFT and CNPHT, representing two groups, which had received high and low radiation dose-exposure to the brain, respectively. Cognitive tests were used to compare CPFT (n = 12) and CNPHT (n = 7) survivors to matched healthy controls (n = 28). HRQOL data was compared to the general population (GP) (n = 1415-1459). Average follow-up was 23 (CPFT) and 19 years (CNPHT). CPFT survivors had significant deficits in all cognitive domains. CNPHT survivors showed results below the control group but differed statistically only on one executive test. HRQOL-ratings indicated that both groups had similar self-reported cognitive problems. CPFT survivors reported more emotional problems and fatigue. Anxiety was seen in both CPFT and CNPHT survivors. This study confirmed long-term cognitive sequelae after RT in adult survivors of CPFT,and possible RT-induced cognitive deficits in adult CNPHT survivors.

Glioblastoma in Beckwith-Wiedemann syndrome: first case report and review of potential pathomechanisms.

Beckwith-Wiedemann syndrome (BWS) is a rare congenital overgrowth syndrome associated with certain childhood tumours. We present the case of a 36-year-old lady with BWS who developed a left frontoinsular secondary glioblastoma. This is the first case report in the literature of glioblastoma associated with BWS. We explore similarities in the molecular pathomechanisms of BWS and glioblastoma.

Matched analysis of patient gender and meningioma resection outcomes.

PURPOSE: Gender is a known social determinant of health (SDOH) that has been linked to neurosurgical outcome disparities. To improve quality of care, there exists a need to investigate the impact of gender on procedure-specific outcomes. The objective of this study was to assess the role of gender on short- and long-term outcomes following resection of meningiomas - the most common benign brain neoplasm of adulthood - between exact matched patient cohorts. MATERIAL AND METHODS: All consecutive patients undergoing supratentorial meningioma resection (n = 349) at a single, university-wide health system over a 6-year period were analyzed retrospectively. Coarsened exact matching was employed to match patients on numerous key characteristics related to outcomes. Primary outcomes included readmission, ED visit, reoperation, and mortality within 30 and 90 days of surgery. Mortality and reoperation were also assessed during the entire follow-up period. Outcomes were compared between matched female and male cohorts. RESULTS: Between matched cohorts, no significant difference was observed in morbidity or mortality at 30 days (p = 0.42-0.75), 90-days (p = 0.23-0.69), or throughout the follow-up period (p = 0.22-0.45). Differences in short-term mortality could not be assessed due to the low number of mortality events. CONCLUSIONS: After matching on characteristics known to impact outcomes and when isolated from other SDOHs, gender does not independently affect morbidity and mortality following meningioma resection. Further research on the role of other SDOHs in this population is merited to better understand underlying drivers of disparity.
