Abstract
Meningiomas are non-glial tumors that are the most common primary brain tumors in adults. Although meningioma can possibly be cured with surgical excision, variations in atypical/anaplastic meningioma have a high recurrence rate and a poor prognosis. As a result, it is critical to develop novel therapeutic options for high-grade meningiomas. This review highlights the current histology of meningiomas, prevalent genetic and molecular changes, and the most extensively researched signaling pathways and therapies in meningiomas. It also reviews current clinical studies and novel meningioma treatments, including immunotherapy, microRNAs, cancer stem cell methods, and targeted interventions within the glycolysis pathway. Through the examination of the complex landscape of meningioma biology and the highlighting of promising therapeutic pathways, this review opens the way for future research efforts aimed at improving patient outcomes in this prevalent intracranial tumor entity.

Abstract
Meningiomas represent the most common type of benign tumor of the extra-axial compartment. Although most meningiomas are benign World Health Organization (WHO) grade 1 lesions, the increasingly prevalent of WHO grade 2 lesion and occasional grade 3 lesions show worsened recurrence rates and morbidity. Multiple medical treatments have been evaluated but show limited efficacy. We review the status of medical management in meningiomas, highlighting successes and failures of various treatment options. We also explore newer studies evaluating the use of immunotherapy in management.

Abstract
OBJECTIVE Visual disturbances that can heal after a complete resection of orbital meningiomas are only about 2.9%. Grading and expression of the progesterone receptor (PR) in orbital meningiomas, according to World Health Organization (WHO) is a useful predictive value of recurrence in the treatment management of orbital meningiomas. This study aims to determine the relationship of PR expression on the grading of orbital meningiomas as tumour prognostic factors. METHODS This cross-sectional observational analysis observed 44 orbital meningioma in Cicendo Eye Hospital Bandung and Hasan Sadikin Hospital between 2017-2020. We performed of mRNA PR with RT-qPCR technique and calculation with the 2∆∆Ct formula. Statistical analysis used the Kruskal-Wallis Test, followed by the Mann-Whitney post hoc test with p<0.005. RESULTS Relative expression of mRNA PR in meningioma orbita grade I to grade III decreased significantly the expression of relative mRNA PR at grade I, II, III of 21.69±44.35, 20.39±26.30 and 1.25±0.85, with Kruskal-Wallis test, p =0.007. Mann Whitney's test results showed relative mRNA PR expression between grades I and II not different (p = 0.055), relative expression mRNA PR between grades I and III differed significantly (p = 0.024), and relative expression mRNA PR between grades I and III was not different (p = 0.638). CONCLUSION mRNA PR expression is viable for prognostic value, predicting recurrence and implementing more effective management of subsequent therapy, it must be combined with other markers to determine the nature of the orbital meningioma.

Abstract
BACKGROUND: Orbital meningiomas can cause visual disturbances, protrusion of the eyes, double vision, and optic nerve abnormalities that significantly decrease vision and eventually lead to blindness. To the best of our knowledge, data on the incidence and pathogenesis of orbital meningioma in Indonesia are non-existent.
AIM: This study aimed to analyze the clinicopathological relationship with orbital meningioma grading.
METHODS: It is a cross-sectional observational analysis on 44 orbital meningioma patients in Dr. Hasan Sadikin General Hospital and the National Eye Center, Cicendo Eye Hospital in 2017–2020. Chi-square analysis and logistic regression with statistical significance (p < 0.05) were engaged in the method.
RESULTS: Orbital meningioma mostly occurred in women aged 30–44 years. Meningioma Grade I was dominated by meningothelial meningioma found in 14 (31.8%) patients, Grade II was atypical meningioma in 9 (20.9%) patients, and Grade III was anaplastic meningioma in 3 patients (6.8%). Clinical symptoms in the form of papillary atrophy (p = 0.046), visual acuity (p = 0.026), proptosis (p = 0.029), and hyperostosis (p = 0.024) were statistically significant and there was a significant difference between Grade I, Grade II, and Grade III using the Chi-square test. Logistic regression results showed that hyperostosis is significantly related to grading the orbital meningioma (p = 0.044) with an odds ratio of 0.206 (IK95% 0.04–0.955).
CONCLUSION: Hyperostosis increases the grading of the orbital meningioma because it is related to the invasion of the tumor into the orbital bone and is a neoplastic process. The presence of hyperostosis which is more common in Grade III meningiomas can be used as one of the most important predictors of meningioma recurrence postoperatively. Nonetheless, our data add to the existing literature the potential points of anti-invasive adjuvant therapy attacks.

Abstract
No portion of this manuscript has previously been presented. Meningiomas, the most common primary intracranial tumors, are histologically categorized by the World Health Organization (WHO) grading system. While higher WHO grade is generally associated with poor clinical outcomes, a significant subset of grade I tumors recur or progress, indicating a need for more reliable models of meningioma behavior. Several groups have developed risk scores based on molecular or immunologic characteristics. These classification schemes show promise, with several models preliminarily demonstrating similar or superior accuracy to WHO grading. Improved understanding of immune system recognition and targeting of meningioma subtypes is necessary to advance the predictive power, as well as develop new therapies. Here, we characterize meningioma molecular drivers, predictive of recurrence and progression, and describe specific aspects of the immune response to meningiomas while highlighting critical questions and ongoing research. Relevant manuscripts of interest were identified using a systematic approach and synthesized into this focused review. Finally, we summarize the ongoing and completed clinical trials for immunotherapy in meningiomas and offer perspective on future directions.

JOURNAL OF NEUROSURGERY: CASE LESSONS 2022; 3:CASE2247. [PMID: 35733823 PMCID: PMC9204931 DOI: 10.3171/case2247] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/28/2022] [Accepted: 03/29/2022] [Indexed: 11/06/2022]
Abstract
BACKGROUND
In the past decade, next-generation sequencing has spurred significant progress in the understanding of cytogenetic alterations that occur in meningiomas. Eighty percent of adult meningiomas harbor pathogenic somatic variants involving NF2, TRAF7, SMARCB1, KLF4, PI3K, or POLR2A. Somatic variants in TRAF7 associated with meningiomas usually localize to the gene’s WD40 domains but are mutually exclusive to germline mutations, which cause a distinctive autosomal dominant syndrome.
OBSERVATIONS
This case involved a 15-year-old girl with bilateral optic nerve sheath meningiomas, diffuse meningiomatosis, and syndromic features, including craniosynostosis, brain anomalies, syndactyly, brachydactyly, epicanthus, and patent ductus arteriosus. Genetic testing of the meningioma specimen 7 years after biopsy showed a pathogenic p.R641C variant within the WD40 domain of the TRAF7 gene. Additional testing of unaffected tissues identified the same variant at lower allele frequencies, consistent with postzygotic somatic mosaicism.
LESSONS
The authors report postzygotic somatic mosaicism for a p.R641C variant in the TRAF7 gene in a patient with bilateral optic nerve sheath meningiomas, diffuse meningiomatosis and a constellation of systemic findings previously recognized in patients with germline mutations of this gene. This is the first report of optic nerve sheath meningioma in a patient with mutation in the TRAF7 gene.

Genome-wide association study identified INSC gene associated with Trail Making Test Part A and Alzheimer's disease related cognitive phenotypes. Prog Neuropsychopharmacol Biol Psychiatry 2021; 111:110393.

Abstract
BACKGROUND The Trail Making Test (TMT) Part A (TMT-A) is a good measure of performance on cognitive processing speed. This study aimed to perform a genome-wide association study of TMT-A in Alzheimer's disease (AD). METHODS A total of 757 individuals with TMT-A phenotypes and 620,901 single nucleotide polymorphisms (SNPs) were extracted from the Alzheimer's Disease Neuroimaging Initiative 1 (ADNI-1) cohort. AD related cognitive phenotypes include TMT-A, TMT-B, Functional Activities Questionnaire (FAQ), Clinical Dementia Rating Sum of Boxes (CDR-SB), and Alzheimer's Disease Assessment Scale-Cognitive Subscale 13 (ADAS13). Multivariable linear regression analysis of TMT-A was conducted using PLINK software. The most TMT-A associated gene was tested with Color Trails Test 1 Form A (CTTA), a culturally fair analog of the TMT-A. Functional annotation of SNPs was performed using the RegulomeDB and Genotype-Tissue Expression (GTEx) databases. RESULTS The best signal with TMT-A was rs1108010 (p = 4.34 × 10-8) at 11p15.2 within INSC gene, which was also associated with TMT-B, FAQ, CDR-SB, and ADAS13 (p = 2.47 × 10-4, 8.56 × 10-3, 0.0127 and 0.0188, respectively). Furthermore, suggestive loci were identified such as FOXD2 and CLTA with TMT-A, GBP1/GBP3 with TMT-B, GRIK2 with FAQ, BAALC and CCDC146 with CDR-SB, BAALC and NKAIN2 with ADAS13. Additionally, the best SNP within INSC associated with CTTA was rs7931705 (p = 6.15 × 10-5). Several SNPs had significant eQTLs using GTEx. CONCLUSIONS We identified several genes/loci associated with TMT-A and AD related phenotypes. These findings offer the potential for new insights into the pathogenesis of cognitive function and Alzheimer's disease.

Abstract
Hormone-associated meningiomas tend to stop growing or decrease in size after cessation of certain progestins, mainly cyproterone acetate. We report three observations on the natural history of hormone-associated intraosseous meningiomas, showing in a first patient that those tumors may grow rapidly under nomegestrol. We then demonstrate the sustained growth of intraosseous hormone-associated meningiomas after cessation of promesgestone and nomegestrol, independently of the intracranial portion, which concurrently decreased in size in the second case or was resected at the time of nomegestrol withdrawal in the third case, thus giving new insights into the tumorigenesis mechanisms of hormone-associated intraosseous meningiomas.

Abstract
Background Spheno-orbital meningiomas (SOMs) constitute a rare cause for orbital proptosis and visual impairment. This study aims to share our outcome experience with regard to vision and exophthalmos following the surgical management of 17 patients with SOM. Methods Retrospective analysis of the case records of all surgically treated SOMs in the last 10 years. Exophthalmos index (EI) was calculated based on preoperative magnetic resonance imaging/computed tomography imaging. Vision was assessed using the Snellen's chart and Goldman's perimeter. Orbital volume was calculated using three-dimensional volume rendering assisted region-of-interest computation. Preoperative duration of symptoms and extent of surgery were the other predictors analyzed. Results Patients' age ranged from 17 to 72 years (mean, 50.57 y; median, 50.0 years). Women represented 13 (76.4%) of the entire study group. Proptosis (14/17; 82.4%) and visual impairment (14/17; 82.3%) were the two most common presenting complaints followed by headache (12/17; 70.1%). Gross total resection (GTR) was achieved in only 2 of the 17 patients (11.8%). Majority of the tumors were benign World Health Organization Grade I meningiomas (14/17; 84%). Mean follow-up time for the entire cohort was 56 months. Postoperatively, proptosis improved in nine (64.3%) and remained static in the rest five (35.7%) of patients. Four patients (28.6%) improved in vision following surgery. Vision remained static in eight patients (57.1%). Vision deteriorated in two (14.3%) patients who had severe preoperative visual deficits. New onset oculomotor palsy, trigeminal dysfunction, and mechanical ocular motility restriction were noticed in three (17.6%), two (11.2%), and six (35.3%) patients, respectively. The mean preoperative orbital volume was 21.68 ± 3.2 cm 3 and the mean postoperative orbital volume was 23.72 ± 3.4 cm 3 . Orbital volume was inversely related to EI. Optic canal (OC) deroofing and extensive orbital wall decompression facilitated visual improvement and proptosis reduction. None of the variables including orbital volume proved to be statistically significant in predicting outcome. Conclusion SOMs constitute a rare subgroup of skull base meningiomas that pose considerable surgical challenges. A surgical strategy aimed at safe maximal resection rather than aggressive GTR provides favorable outcome with less morbidity. Adequate bony decompression of the orbital walls and OC provides satisfactory improvements in proptosis and vision. Residual disease is common, but the risk of symptomatic recurrence is low especially when combined with adjuvant radiotherapy. Visual outcome is likely to be poor in patients presenting with severely compromised vision.

Abstract
AIM To investigate neurofibromatosis type 2 (NF2) gene mutation at mRNA levels in sporadic orbitocranial meningioma and its association with progesterone receptor (PR) mRNA expression. METHODS This was a case-control study. Thirty-four sporadic meningioma patients with no familial NF2-related meningioma history were recruited. They were interviewed for their obstetric, gynecologic, and contraception history. PR investigation was performed with real-time polymerase chain reaction (PCR). NF2 mutation was investigated using Qbiomarker Somatic Mutation PCR Assay at NF2 mRNA level after its cDNA extraction (four mRNA mutation cytoband coordinates for nucleotide change: c.634C>T/p.Q212, c.655G>A/p.V219M, c.784C>T/p.R262 and c.1228C>T/p. Q410). RESULTS After mutation analysis at mRNA level, NF2 gene mutation was found in 35.29% patients. Non-mutation group was strongly associated with exogenous hormonal exposure (non-mutation vs mutation: 95.5% vs 83.3%, P<0.001). PR mRNA was found significantly lower in non-mutation group (P=0.033) which presumed as long term exogenous progesterone exposure. However, mutation group was associated with higher rate of progression to grade II (mutation vs non-mutation, 18.2% vs 5%, P<0.001) and was associated more in fibrous and anaplastic tumor tissue. CONCLUSION NF2 mutation-meningioma is associated with higher grade of meningioma. Non NF2 mutation-meningioma is strongly associated with exogenous progesterone exposure and lower PR expression.

Abstract
Granular cell astrocytoma (GCA) is a rare adult infiltrating glioma subtype. We studied a series of 39 GCAs. Median age of presentation was 57.8 years and most cases developed in the frontal or temporal lobes. Tumors included grade II (n = 14), grade III (n = 11), and grade IV (n = 14) by WHO criteria. Granular cell morphology was diffuse in 31 (79%) cases and partial in eight (21%). Immunohistochemistry showed frequent positivity for GFAP (28 of 31), OLIG2 (16 of 16), and CD68 (27 of 30), but HAM56, CD163, and IBA-1 histiocytic markers were all negative (22 of 22). IDH1(R132H) was negative in all the cases tested (16 of 16), while ATRX expression was retained (12 of 12). Cytogenetics demonstrated monosomy 10 (6 of 6) cases, +7 in 4 (of 6), -13q in 4 of 6, and -14 in 4 of 6. Next-generation sequencing demonstrated mutations in PTEN/PIK3 genes in 6/13 (46%), NF1 in 3 of 10 (30%), TP53 in 3 of 13 (23%), PALB2 in 3 of 10 (30%), STAG2 in 3 of 10 (30%), EGFR mutation/amplification in 3 of 13 (23%), and AR in 2 of 10 (20%). CDKN2A/B deletion was identified in 5 of 13 (30%) cases (homozygous deletion in 4). The TERT C228T mutation was identified in 9 of 13 (69%). No mutations were encountered in IDH1, IDH2, CIC, FUBP1, H3F3A, BRAF or ATRX genes. The mean overall survival was 11.3 months. Patients >60 years old at diagnosis had a worse survival than patients <60 years (P = 0.001). There were no statistically significant differences in survival by WHO grade, extent of granular cell change, sex or MIB-1 (P > 0.05). GCA is a variant of IDH-wildtype diffuse glioma with aggressive behavior irrespective of grade and extent of granular cell morphology, and with molecular genetic features corresponding to primary glioblastoma.

Meningiomas are the most frequent primary brain tumor. Usually, they are curable by surgery, but even after seemingly complete resection, some low-grade lesions recur. Despite recent improvements, signatures having prognostic value in grade I tumors remain poorly characterized. The frequency and delicate location of these tumors suggest that the risk of recurrence might be more accurately predicted. Herein, we show an easy way to evaluate the methylation status of meningiomas and its correlation with the prognosis of the disease. A series of 120 meningiomas, including primary tumors and recurrences, were analyzed histopathologically, and 24 tumor suppressor genes (TSGs) were studied by methylation-specific multiple ligation probe amplification. Long-term follow-up was conducted to classify patients with grade I primary tumors according to their outcomes. We found that hypermethylation in at least one TSG is frequent. The number of hypermethylated TSG per case was significantly higher in recurrences than in primary tumors and in primary benign meningiomas that recurred than in tumors from patients who showed no evidence of disease during follow-up. Finally, hypermethylation in RASSF1A, MLH1, and CDKN2B was an independent prognostic factor associated with the time to recurrence of these benign tumors that were biologically aggressive. To our knowledge, this is one of the widest studies of primary grade I tumors of patients who developed a tumor recurrence. The frequency of epigenetic changes suggests that hypermethylation is an early event in meningiomas, whereas the accumulation of epigenetic changes is related to greater biological aggressiveness and may be a signature of potential clinical relevance.

Abstract
PURPOSE To evaluate the clinical behavior of spheno-orbital meningiomas with regard to World Health Organization (WHO) tumor grade and Ki-67, a cellular marker of proliferation. METHODS A retrospective review over a 16-year period of the demographic, clinical, radiographic, and surgical data of all patients with spheno-orbital meningioma who underwent surgical resection. Tumor specimens were examined histologically using the current WHO 2016 classification and immunohistochemically using Ki-67/MIB-1 monoclonal antibody. RESULTS Thirty-eight patients met all inclusion criteria: 78.9% of tumors were WHO grade I with a mean Ki-67 of 3.76, and 93% of patients were clinically stable at last follow up; 10.5% of lesions were WHO grade II (atypical) with a mean Ki-67 of 14.93, and 10.5% of lesions were WHO grade III (anaplastic) with a mean Ki-67 of 58.3. All grade II and III meningiomas exhibited an aggressive clinical course. There were statistically significant correlations between disease clinical progression and WHO tumor grade (p < 0.001), between disease clinical progression and Ki-67 (p < 0.001), and between increasing Ki-67 index and higher WHO grade (p < 0.001). For WHO grade I lesions, a Ki-67 of ≥3.3 correlated with recurrence (p = 0.0256). Overall, disease-specific mortality occurred in 5 (13%) patients. CONCLUSIONS Ki-67 index is a valuable marker to use in conjunction with WHO grade to predict meningioma behavior, particularly in histologically borderline lesions, and possibly to identify a subset of WHO grade I tumors at risk of recurrence. This combination of methods can aid in tailoring treatment and surveillance strategies.

Abstract
Tumors of the inner ear and adjacent structures often present with hearing loss, tinnitus and vertigo due to compression of the traversing cranial nerves. More than 90% of the tumors of the inner ear with or without expansion into the cerebellopontine angle are histologically diagnosed as vestibular schwannomas. Less common tumorous lesions include ectopic meningiomas located in the petrous bone, glomus tympanicum paragangliomas or endolymphatic sac tumors (ELST) originating in the vestibular recess. Most tumors are sporadic, but hereditary disorders have to be considered. Bilateral vestibular schwannomas are indicative of neurofibromatosis type 2 and ELST in conjunction with other abdominal tumors indicates von Hippel-Lindau disease. The neuropathological diagnostics and grading guides the subsequent therapy of these mostly benign lesions.

Abstract
OBJECTIVE To examine the efficacy of spheno-orbital meningioma (SOM) resection aimed at symptomatic improvement, rather than gross total resection, followed by radiation therapy for recurrence. METHODS A retrospective review of all patients having undergone resection between 2000 and 2016 was performed. Demographics, operative details, postoperative outcomes, recurrence rates, and radiation treatment plans were analyzed. Statistical analysis was performed to assess for factors affecting recurrence (Fisher exact and Student t test), changes in exophthalmos index (EI) (Student t test), and progression-free survival (Kaplan-Meier and log rank). RESULTS Twenty-five patients were included; 92% of participants were women. Mean age was 51 years. World Health Organization grades were I (n = 21) and II (n = 4). Simpson grades were I (n = 14), II (n = 3), and IV (n = 8). Mean follow-up time was 44.8 months. Proptosis was significantly improved at the 3- to 6-month postoperative visit (mean ΔEI, 0.15; P < 0.05) and at last follow-up (mean ΔEI, 0.13; P < 0.05). Visual acuity was either improved or stable in 18 of 19 patients. There were 12 recurrences; mean time to recurrence was 21.8 months. Increased recurrence rate was significantly associated with younger age. Eight patients received fractionated radiation at time of recurrence. To date, all treated patients are progression free. CONCLUSIONS Among this cohort, surgery provided a lasting improvement in proptosis and improved or stabilized visual deficits. Surgery followed by radiation at recurrence provided excellent tumor control and lends credence to the growing body of literature demonstrating effective control of subtotally resected skull base meningiomas.
