  • [Title] Carbonic anhydrases in meningiomas: association of endothelial carbonic anhydrase II with aggressive tumor features.
  • OBJECT: Carbonic anhydrase (CA) II and IX are enzymes involved in pH homeostasis and have been shown to be upregulated in several types of cancer.
  • In this study, the authors evaluate the expression of CA II and IX in meningiomas and assess their relationship to patient age, tumor type and grade, tumor sex hormone receptor status, tumor cell proliferation, and tumor recurrence.
  • METHODS: This study was conducted in consecutive patients who underwent meningioma surgeries at Tampere University Hospital between 1989 and 1999.
  • The expression of CA II and IX was studied immunohistochemically using a tissue microarray technique and specific antibodies.
  • RESULTS: Immunohistological staining with CA II and IX was assessed in 443 primary and 67 recurrent tumor specimens.
  • Of these samples, 455 were benign (WHO Grade I), 49 atypical (Grade II), and 6 malignant (Grade III).
  • Endothelial cells in 14.8% of the tumors stained positively for CA II.
  • Endothelial CA II expression correlated with increasing histological grade (p=0.002), and tumor proliferation rates were higher in CA II+ versus CA II- cases (p=0.002).
  • Androgen receptor-negative tumors were found to be CA II+ significantly more often than androgen receptor-positive tumors (p=0.001).
  • CONCLUSIONS: Carbonic anhydrase II positivity in the endothelium was associated with cell proliferation and malignancy grade.
  • These results suggest that CA II expression is associated with malignant progression of meningiomas and could thus be a target molecule for anticancer therapy.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • OBJECTIVE: To test the relationship between the angiogenetic potential of intracranial meningiomas and clinical/prognostic features such as World Health Organization (WHO) grade, peritumoral edema, tumor border shape, and recurrence using rat corneal angiogenesis assay.
  • METHODS: Fifteen WHO grade I (typical), 10 WHO grade II (atypical), and 5 WHO grade III (malignant) meningioma samples were implanted in the micropockets formed on rat corneas, and the number of developed vessels were counted on days 5, 10, 15, and 20.
  • RESULTS: The angiogenic potential of WHO grade II tumors was significantly lower than that of grade III tumors and higher than that of grade I tumors throughout the experiment.
  • However, multivariate analysis identified WHO grade, recurrence, and peritumoral edema as significant predictors of a high angiogenic potential.
  • CONCLUSION: Our findings, based on a dynamic in vivo model to examine angiogenesis, demonstrate that the angiogenic potential of meningiomas is correlated with WHO grade, recurrence, and possibly with tumor border shape and peritumoral edema.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • The roles of bone morphogenetic proteins (BMPs) and their receptors (BMPRs) in meningioma biology are not known.
  • In this study, frozen tissues from 26 World Health Organization Grades I to III meningiomas were analyzed by Western blot for BMP-2/4, BMPR IA, and BMPR II, and activation of downstream p-Smad1, p38 mitogen-activated protein kinase (MAPK), and p44/42 MAPK signaling molecules.
  • Primary meningioma cultures from 11 meningiomas were treated with BMP-4 and evaluated for cell proliferation and signaling pathway activation.
  • Bone morphogenetic protein 4 was variably detected in adult leptomeninges but was detected in 89% or 84% of Grade I meningiomas and in 60% of Grade II meningiomas by Western blot and immunohistochemistry, respectively.
  • Bone morphogenetic protein receptors IA and II were detected in leptomeninges and in all meningiomas studied, and activated Smad1 was detected in all meningiomas studied.
  • Bone morphogenetic protein 4 stimulated meningioma cell proliferation and phosphorylation/activation of Smad1 but not p38 MAPK or p44/42 MAPK in vitro, and it was detected in conditioned media from 4 of 7 cultures.
  • These findings suggest that BMP-4 and BMPRs may play autocrine/paracrine roles and interact with other transforming growth factor-beta superfamily members in regulating meningioma growth and differentiation.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Patterns of failure after stereotactic radiotherapy of intracranial meningioma.
  • The aim of this work is to evaluate patterns of failure in patients with recurrent meningioma after stereotactic radiotherapy.
  • Of 411 patients with intracranial meningioma treated with radiotherapy at our institution, 22 patients with local tumor progression diagnosed by magnetic resonance imaging (MRI) after radiotherapy (RT) were identified and further investigated.
  • The histologic grade of the meningiomas was World Health Organization (WHO) grade I in 54.5%, WHO grade II in 27.3%, and WHO grade III in 9.1% of cases.
  • Median recurrence-free survival was 46 months for patients with benign meningioma (WHO grade I) and 31.5 months for patients with higher-grade meningioma (WHO grade II/III).
  • In the WHO grade I group, three recurrences were central and nine were marginal, whereas in the WHO grade II/III group seven recurrences were central and one was marginal.
  • Median time to local tumor progression and site of local recurrence significantly depended on histological grade of meningioma.
  • Regarding site of failure, improvement of dose coverage for benign meningiomas and dose escalation for high-grade tumors might further improve therapy outcome.

  • [Title] 1-11C-acetate versus 18F-FDG PET in detection of meningioma and monitoring the effect of gamma-knife radiosurgery.
  • METHODS: Twenty-two patients with the neuroradiologic diagnosis of meningioma were examined by 1-(11)C-acetate and (18)F-FDG PET on the same day.
  • There were 12 cases of histopathologically proven meningioma (8 grade I, 2 grade II, and 2 grade III), 1 of tuberculous granuloma, and 1 of degenerative tissue.
  • RESULTS: The (18)F-FDG PET study revealed a hypometabolic focus in 17 meningiomas (8 grade I, 1 grade II, and 8 unknown grade) and hypermetabolism in 1 grade II and 2 grade III meningiomas.
  • The standardized uptake value for 1-(11)C-acetate was not different from that for (18)F-FDG (mean +/- SD, 3.16 +/- 1.75 vs. 3.22 +/- 1.50, P = 0.601), but the tumor-to-cortex ratio for 1-(11)C-acetate was higher than that for (18)F-FDG (3.46 +/- 1.38 vs. 0.93 +/- 1.08, P < 0.005). (18)F-FDG was able to differentiate grade I from grade II-III meningiomas, whereas 1-(11)C-acetate was unable to do so.
  • Tuberculous granuloma had a high 1-(11)C-acetate and (18)F-FDG uptake similar to that of grade II/III meningioma.
  • However, 1-(11)C-acetate was not useful for evaluating the tumor grade. (18)F-FDG was found to be less useful than 1-(11)C-acetate for evaluating the extent of meningiomas and the response to radiosurgical treatment but may be useful for differentiating benign from malignant meningiomas. (18)F-FDG and 1-(11)C-acetate are complementary for assessing diverse cell metabolism of meningioma.

  • The identity and functions of surface proteins on human leptomeningeal and meningioma cells are incompletely characterized.
  • Sections of 20 normal adult brains with leptomeninges and 49 World Health Organization (WHO) grade I, 21 grade II, and 2 grade III meningiomas were analyzed using an extensively characterized monoclonal antibody to mesothelin and streptavidin-biotin complex immunohistochemistry.
  • Mesothelin immunoreactivity was detected in the arachnoid in 6 of 20 cases and in 23 of 49 WHO grade I meningiomas.
  • It was also detected in 7 of 21 WHO II tumors and 1 of the 2 anaplastic meningiomas.
  • These findings suggest that mesothelin is expressed in at least some arachnoid and meningioma cells.

  • [Title] Osteopontin expression is a valuable marker for prediction of short-term recurrence in WHO grade I benign meningiomas.
  • Prediction of recurrence remains a challenge in histopathological benign/grade I tumors.
  • Thirty-two patients were enrolled, and 23 benign non-recurrent meningiomas and 9 benign recurrent meningiomas were followed for a mean of 34 months after complete surgical resection (Simpson grades I and II).
  • Our results showed that meningioma recurrence correlated significantly with OPN IHC score (P = 0.001).
  • We concluded that OPN IHC score may play a role in prediction of the recurrence of the grade I meningiomas.
  • Moreover, determination of the OPN Allred score is a reliable, quantitative tool for predicting recurrence-free time in benign meningioma patients.

  • According to the provided World Health Organization (WHO) grading, 84, 18 and five cases were classified as grade I, II and III, respectively.
  • Even in meningiomas of more than grade II, the expressions of cell adhesion molecules were detected in all cases.
  • The present study demonstrates that cell adhesion molecules are ubiquitously expressed in all variants of meningioma and may be involved in the tumor morphogenesis.
  • The present study also suggests that these markers may be useful for the differential diagnosis of meningioma.

  • CONCLUSIONS: Expression of the IL-4Ralpha and IL-13Ralpha1 chains and absence of IL-2gammac expression established that meningiomas expressed type II IL-4Rs.
  • These receptors may serve as a target for cytotoxin/immunotoxin therapy in patients with meningioma who are not amenable to surgical resection or for recurrent tumors.

  • [Title] Intracranial meningioma in children: different from adult forms? A series of 21 cases.
  • The goal of this study of pediatric meningiomas was to establish their epidemiological profile as well as their clinical and radiological features, to assess the long-term outcome, and compare this result with adult meningioma.
  • PATIENT AND METHODS: We conducted a retrospective study from June 1983 to June 2007; during this period 521 patients underwent surgery for primary meningioma at the Rabat Hospital, Department of Neurosurgery.
  • Surgery achieved a Simpson grade I resection in 47%; 62% of the tumors were grade I and 24% were grade II based on World Health Organization pathological classification.
  • CONCLUSION: Pediatric meningiomas are larger than those found in the adult population; there is a male predominance with high incidence of a cystic component and high-grade meningiomas, thus explaining the increased recurrence rate despite the multimodal treatment.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • OBJECT: The goal in this study was to determine if proton ((1)H) MR spectroscopy can differentiate meningioma grade and is associated with interpretations of biological behavior; the study was performed using ex vivo high-resolution spectra indicating metabolic characteristics.
  • Of these meningiomas, 46 were WHO Grade I, 14 were WHO Grade II, and 8 were WHO Grade III.
  • RESULTS: The absolute concentrations of total alanine and creatine were decreased in high-grade compared with low-grade meningiomas, as was the ratio of glycine to alanine (all p < 0.05).
  • CONCLUSIONS: These data indicate that meningioma tissue can be characterized by metabolic parameters that are not typically identified by histopathological analysis alone.
  • Creatine, glycine, and alanine may be used as markers of meningioma grade, recurrence, and the likelihood of rapid recurrence.
  • These data validate a previous study of a separate group of Grade I meningiomas.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • The aim of this study was to identify genes related to meningioma progression from the benign state to the atypical and anaplastic states by examining 1p LOH and the promoter methylation of RASSF1A and p73.
  • METHODS: The authors studied 40 surgical specimens (22 WHO Grade I, 11 Grade II, and seven Grade III) obtained in 37 patients with meningioma.
  • RESULTS: No 1p LOH was detected in the Grade I tumors, whereas it was detected in more than 80% of the Grade II and III tumors.
  • Methylation of the p73 promoter was observed in 81.8 and 71.4% of the Grade II and III tumors, respectively, but it was not observed in any of the Grade I tumors; methylation of the RASSF1A promoter was observed in 18.2, 63.6, and 42.9% of the Grade I, II, and III tumors, respectively.
  • Interestingly, 1p LOH and p73 promoter hypermethylation were detected in the malignantly transformed tumors but not in the lower-grade primary ones.
  • CONCLUSIONS: Based on the hypothesis that meningiomas cumulatively acquire genetic alterations and thus progress from the benign to the atypical and anaplastic states, genetic alterations in the methylation status of p73 or RASSF1A along with 1p LOH may result in the malignant transformation of a meningioma.

  • [Title] Constitutive activation of signal transducer and activator of transcription 3 regulates expression of vascular endothelial growth factor in human meningioma differentiation.
  • The function of STAT3 in the pathogenesis of meningioma remains unknown.
  • In this study, we investigated the role of JAK1/STAT3 regulating vascular endothelial growth factor (VEGF) expression in the occurrence and progression of human meningioma.
  • METHODS: We detected the expression of JAK1, p-JAK1, STAT3, p-STAT3, and VEGF in human meningioma and normal dura tissues by RT-PCR, Western blot analysis, and immunohistochemistry.
  • RESULTS: JAK1, p-JAK1, STAT3, p-STAT3, and VEGF showed high expression in grade I and grade II meningioma.
  • The level of STAT3 activation was associated with VEGF expression; all meningioma tumors that expressed p-STAT3 also expressed VEGF.
  • Both frequency of positivity and expression were enhanced with increasing tumor grade; high frequencies and levels were found in grade II tumors, with no expression detected in normal dura tissues (P < 0.05).
  • CONCLUSIONS: VEGF is directly regulated by constitutive STAT3 activity and associated with meningioma differentiation.
  • STAT3 has an important role in the occurrence and development of human meningioma by regulating VEGF expression.

  • All histological sections were reviewed and reclassified according to World Health Organization (WHO) 2000 guidelines as benign (Grade I), atypical (Grade II), or anaplastic (Grade III) meningiomas.
  • Seventeen (68%) of the cases were reclassified as follows: WHO Grade I (five cases), Grade II (11 cases), and Grade III (one case).
  • The 3-year progression-free survival (PFS) rates for the Grades I, II, and III, and malignant progression groups were 100, 83, 0, and 11%, respectively (p < 0.001).
  • In the Grade II group, the 3-year PFS rates for patients treated with SRS and SRT were 100 and 33%, respectively (p = 0.1).
  • CONCLUSIONS: Stereotactic radiation treatment provided effective local control of "aggressive" Grade I and Grade II meningiomas, whereas Grade III lesions were associated with poor outcome.
  • The outcome of cases in the malignant progression group was intermediate between that of the Grade II and Grade III groups, with the lesions showing a tendency toward malignancy.

  • [Title] The accuracy of meningioma grading: a 10-year retrospective audit.
  • Although descriptive classifications of meningioma subtypes are well established, there has been inconsistency in the categorization of meningiomas into benign, atypical and anaplastic groups.
  • The aim of this study was to reassess the incidence of atypical (grade II) meningiomas over a 10-year period by applying the World Health Organization (WHO) 2000 classification system.
  • A secondary aim was to determine if grade II and III tumours were becoming more common.
  • On reclassification, 78% of the meningiomas were classified as grade I, 20.4% as grade II and 1.6% as grade III.
  • With regard to grade II meningiomas classified by using the WHO 2000 classification system, 38.1% had originally been classified as grade I prior to 2000, whereas 13.6% had originally been classified as grade I after 2000.

  • [Title] Chordoid meningioma: a clinicopathologic study of 11 cases at a single institution.
  • Chordoid meningioma is an uncommon variant of meningioma, which histologically bears a great resemblance to chordoma and often follows an aggressive clinical course.
  • Thirteen specimens of chordoid meningioma belonging to 11 patients were obtained at a single institution from 1995 to 2009.
  • Six tumors (46%) were classified as benign (grade I) and seven tumors (54%) atypical (grade II), if based solely on histologic grading irrespective of chordoid or clear cell components in our cases.

  • [Title] Chordoid meningioma: presentation of two case reports, review of the literature, and plea for data standardisation.
  • Chordoid meningioma is a rare variant of meningioma with histological features resembling those of chordoma.
  • This tumour should have a greater risk of recurrence and aggressive growth (WHO grade II).
  • We report two cases of chordoid meningioma occurring in adult female patients.
  • In our two patients (aged 28 and 60 years with chordoid meningioma of the convexity and left-sided outer sphenoid wing, respectively) we centred on some rarely discussed aspects of the tumour.
  • In both cases, the tumour was removed by radical surgery (Simpson grade I resection) with a normal post-operative course.
  • We regard the factors under consideration in our study (i.e. absence of edema, dural supply, low VEGF expression and radical Simpson grade I resection) as an important contribution to the discussion of the biological behaviour of chordoid meningioma.

  • [Title] Pathodiagnostic parameters for meningioma grading.
  • In this study the relationship between pathodiagnostic parameters, histological grade, and MIB-1 monoclonal antibody expression in meningioma diagnosed over 10 years in Shohada Hospital, Tehran, was assessed.
  • All slides stained with hematoxylin and eosin were reviewed by two independent pathologists and all the diagnoses reconfirmed; histological anaplasia was classified according to the grading of the WHO Working Group 2000 as benign (Grade I), atypical with incipient signs of anaplasia (Grade II), or overtly anaplastic (Grade III).
  • Histopathological study of completely resected meningiomas showed that loss of architecture, frequent mitotic figures, a high cellularity, increased nucleo-cytoplasmic ratio, a prominent nucleolus, brain invasion, and necrosis were correlated with the grade of the meningiomas.
  • Overall, the mitotic count was the most important marker for tumor grade.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • OBJECTIVES: (i) To examine blood perfusion and metabolic activity of various brain tumours using radionuclide cerebral angiography (RCA) and single-photon emission tomography (SPET) after a single dose of Tc-methoxyisobutylisonitrile (MIBI). (ii) To examine if the inclusion of RCA can improve insight into the relative contribution of tumour perfusion to the uptake of MIBI shown by SPET, and to improve evaluation of tumour biology. (iii) To determine the value and the roles of MIBI in the management of brain tumour patients.
  • METHODS: Fifty adult patients (38 male, 12 female) with a total of 56 intracranial space-occupying lesions have been included prospectively, 37 of which were newly diagnosed and the remaining with signs of recurrence/rest of earlier resected and irradiated brain tumours.
  • (ii) early uptake index (E);.
  • RESULTS: Mean P of various brain tumours (low-grade gliomas 0.98, anaplastic gliomas 1.14, glioblastoma multiforme 1.20, metastases 1.09, lymphomas 1.08) differ little from each other and do not exceed maximal physiologic regional variations of cerebral perfusion (1.33), with the exception of meningioma (1.87, F=2.83, P=0.015).
  • The receiver operating characteristics curve analysis of P showed that for the cut-off value of 1.45 the sensitivity for distinguishing meningioma from other tumours is 75%, specificity 87%, positive predictive value 33% and negative predictive value 97%.
  • Mean E of malignant brain tumours (8.3, n=31, 23 primary, eight secondary), except anaplastic gliomas (3.5, n=5), differed significantly (P=0.02) from those of benign gliomas (3, n=9) but not from that of meningioma (11.9, n=4).
  • If the perfusion index is less than 1.45, then meningioma can be ruled out.
  • Early SPET is recommendable for distinguishing glioblastoma from low-grade gliomas, as a complement to standard magnetic resonance imaging and/or computed tomography.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • Chordoid meningioma, World Health Organization grade II, is an uncommon variant of meningioma with a propensity for aggressive behavior and increased likelihood of recurrence.
  • A formal comparison of the immunohistochemical features of chordoid meningioma versus tumors with significant histologic overlap has not been previously reported.
  • In this study, immunohistochemical staining was performed with antibodies against D2-40, S100, pankeratin, epithelial membrane antigen (EMA), brachyury, and glial fibrillary acidic protein (GFAP) in 4 cases of chordoid glioma, 6 skeletal myxoid chondrosarcomas, 10 chordoid meningiomas, 16 extraskeletal myxoid chondrosarcoma, 18 chordomas, 22 low-grade chondrosarcomas, and 27 enchondromas.
  • Immunostaining with D2-40 showed positivity in 100% of skeletal myxoid chondrosarcomas, 96% of enchondromas, 95% of low-grade chondrosarcomas, 80% of chordoid meningiomas, and 75% of chordoid gliomas.
  • Staining with S100 demonstrated diffuse, strong positivity in all (100%) chordoid gliomas, skeletal myxoid chondrosarcomas, low-grade chondrosarcomas, and enchondromas, 94% of chordomas, and 81% of extraskeletal myxoid chondrosarcomas, with focal, moderate staining in 40% of chordoid meningiomas.
  • EMA was the most effective antibody for differentiating chordoid meningioma from skeletal myxoid chondrosarcoma, low-grade chondrosarcoma, and enchondroma, whereas D2-40 was the most effective antibody for differentiating chordoid meningioma from extraskeletal myxoid chondrosarcoma and chordoma.
  • Our findings demonstrate that in conjunction with clinical and radiographic findings, immunohistochemical evaluation with a panel of D2-40, EMA, brachyury, and GFAP is most useful in distinguishing chordoid meningioma from chordoid glioma, skeletal myxoid chondrosarcoma, extraskeletal myxoid chondrosarcoma, chordoma, low-grade chondrosarcoma, and enchondroma.
  • A lack of strong, diffuse S100 reactivity may also be useful in excluding chordoid meningioma.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • METHODS: The current (2000) WHO classification was used to grade 57 meningiomas treated surgically at one institution.
  • RESULTS: Use of the current criteria downgraded seven of 15 atypical meningiomas (WHO grade II, MII) to grade I (MI), and four of six anaplastic tumours (WHO grade III, MIII) to grade II.
  • Indications for radiotherapy/radiosurgery and MRI follow up protocols varied substantially with the histological grade and between institutions--for example, after an incomplete resection, radiotherapy/radiosurgery recommendations differed between MI and MII in 30 of 58 units (52%), and between MII and MIII in 34 of 56 units (61%).
  • The relatively large number of meningiomas classified as atypical/WHO grade II in current practice would argue against an uncritically aggressive approach to these tumours.

  • Primary meningioma cells cultured from 10 human meningiomas were also treated with acidic FGF and evaluated for cell proliferation or activation/phosphorylation of p44/42 MAPK, Akt, and STAT3.
  • RESULTS: Immunoblotting demonstrated the presence of FGFR3 in 12 (71%) of 17 primarily fibroblastic and transitional WHO Grade I meningiomas.
  • The FGFR3 was detected in 4 (80%) of 5 WHO Grade II, and 2 of 2 Grade III tumors.
  • Acidic FGF was detected in 3 (18%) of 17 Grade I, 1 (20%) of 5 Grade II, and 1 (50%) of 2 Grade III meningiomas.
  • In WHO Grade I meningiomas, 3 of 6 tumors with no detectable FGFR3 had no detectable p-STAT3.
  • In WHO Grades II and III meningiomas, FGFR3 expression was associated with p-STAT3, p-Akt, and p-p44/42 MAPK expression.
  • No mutations were demonstrated in exons 7 or 10 by polymerase chain reaction in any meningioma.
  • Treatment with acidic FGF, a ligand for FGFR3, stimulated meningioma cell proliferation and activation of Akt and STAT3 in primary meningioma cell cultures.
  • CONCLUSIONS: These findings suggest that FGFR3 and acidic FGF are expressed in adult human leptomeninges as well as WHO Grades I and II meningiomas.
  • Fibroblast growth factor receptor-3 activation stimulates meningioma cell proliferation by activation of the phosphoinositide 3 kinase-Akt-PRAS40-mTOR and STAT3 pathways.

  • [Title] WHO grade II and III meningiomas: a study of prognostic factors.
  • Grades II and III meningiomas have been less well studied and are not well controlled because of their aggressive behaviour and recurrences.
  • This study was performed on 199 adults treated for WHO grade II (166 patients) or grade III (33 patients) meningiomas between 1990 and 2004 in the Neurosurgery Departments of five French University Hospitals.
  • For patients with grade II meningiomas, the 5- and 10-year OS rates were 78.4 and 53.3%, respectively, while, for patients with grade III meningiomas, the corresponding values were 44.0 and 14.2%.
  • For patients with grade II meningiomas, the 5- and 10-year PFS rates were 48.4 and 22.6%, respectively, the corresponding values for patients with grade III meningiomas being 8.4 and 0%.
  • For the grade II meningiomas, univariate analysis showed that age < 60 years (P < 0.0001) and Simpson 1 resection (P = 0.055) were associated with a longer OS.
  • For the grade III meningiomas, univariate analysis showed that age < 60 years (P < 0.0001) and RT (P = 0.036) were associated with a longer OS.
  • Histological grade II was found to be associated with a longer PFS (P = 0.0032) and RT reduced the PFS in grade II meningiomas (P = 0.0006) There were no other prognostic factors in terms of PFS for grades II and III meningiomas in univariate analysis.
  • Multivariate analysis confirmed that age (< 60 years), Simpson 1 and histological grade II were independent prognostic factors for survival.
  • This retrospective study might improve the management of grades II and III meningiomas.
  • Prospective trials should delineate strong therapeutic guidelines for high-grade meningiomas.

  • [Title] Genomic profiling reveals alternative genetic pathways of meningioma malignant progression dependent on the underlying NF2 status.
  • EXPERIMENTAL DESIGN: We identified genetic alterations associated with histologic progression of 36 paired meningioma samples in 18 patients using 500K SNP genotyping arrays and NF2 gene sequencing.
  • RESULTS: The most frequent chromosome alterations observed in progressing meningioma samples are early alterations (i.e., present both in lower- and higher-grade samples of a single patient).
  • In our series, NF2 gene inactivation was an early and frequent event in progressing meningioma samples (73%).
  • Chromosome alterations acquired during progression from grade I to grade II meningioma were not recurrent.
  • Progression to grade III was characterized by recurrent genomic alterations, the most frequent being CDKN2A/CDKN2B locus loss on 9p.
  • This pattern of alterations could thus be used as markers in clinical practice to identify tumors prone to progress among grade I meningiomas.

  • BACKGROUND: Endothelin-1 (ET-1), a vasoconstrictor and mitogen, has recently been implicated in the pathogenesis of human glioblastoma, neuroblastoma, and meningioma.
  • Because only immunoreactive ET-1 has been observed within human astrocytic tumor cells, the authors investigated the localization of the entire ET-1 system (ET-1 mRNA, ET-1, ECE-1, ETA and ETB receptors) in surgical samples of human diffuse astrocytomas WHO Grade II (n = 6).

  • A modified McCormick Scale (Grades I-V) was used to assess ambulatory ability (I = normal ambulation; II = mild motor sensory deficit, independent without external aid; III = independent with external aid; IV = care required; and V = wheelchair required).
  • The tumor types included astrocytoma (12 cases), ependymoma (46 cases), hemangioblastoma (16 cases), cavernous hemangioma (17 cases), and others (15 cases overall: gangliocytoma, 1; germ cell tumor, 1; lymphoma, 3; neurinoma, 1; meningioma, 1; oligodendroglioma, 1; sarcoidosis, 2; glioma, 1; and unknown, 4).
  • According to the preoperative McCormick Scale, ambulatory status was classified as Grades I, II, III, IV, and V in 41(38%), 30 (28%), 14 (13%), 19 (19%), and 2 (2%) patients, respectively.
  • The number of patients who did not lose ambulatory ability or who achieved an ambulatory status of Grade I or II postoperatively was 33 (80%), 21 (70%), 10 (71%), 8 (42%), and 1 (50%) in patients with preoperative Grades I, II, III, IV, and V, respectively.
  • Total excision was performed in 31 (79%) of 39 patients with preoperative Grade I, 12 (40%) of 30 patients with Grade II, 7 (50%) of 14 patients with Grade III, and 9 of 21 patients (38%) with Grade IV or V, indicating that the rate of total excision was significantly higher in patients with Grade I status.
  • Total excision in patients with Grade I or II ambulation was associated with a good prognosis for postoperative mobility.

  • METHODS: Fifty-nine patients (27 men and 32 women) with intracranial meningioma who underwent preoperative FDG PET and subsequent surgical resection were enrolled.
  • The tumor to gray matter ratio (TGR) of FDG uptake was calculated and a receiver-operating characteristic (ROC) curve of the TGR was drawn to determine the cutoff value of the TGR for detection of high-grade meningioma.
  • Further, univariate analysis with the log-rank test was performed to assess the predictive factors of meningioma recurrence.
  • RESULTS: The TGR in high-grade meningioma (WHO grade II and III) was significantly higher than that in low-grade ones (WHO grade I) (p=0.002) and significantly correlated with the MIB-1 labeling index (r=0.338, p=0.009) and mitotic count of the tumor (r=0.284, p=0.03).
  • The ROC analysis revealed that the TGR of 1.0 was the best cutoff value for detecting high-grade meningioma with a sensitivity of 43%, specificity of 95%, and accuracy of 81%.
  • In the log-rank test, the TGR, MIB-1 labeling index, presence of brain invasion, and WHO grade were significantly associated with tumor recurrence.
  • The cumulative recurrence-free survival rate of patients with a TGR of 1.0 or less was significantly higher than that of patients with a TGR of more than 1.0 (p=0.0003) CONCLUSION: FDG uptake in meningioma was the significant predictive factor of tumor recurrence and significantly correlated with the proliferative potential of the tumor.

  • Several studies have indicated NF2 gene inactivation as an early tumorigenic event unrelated to the histological grade or clinical behavior.
  • The average of expression of WHO grade I and II meningiomas was higher than the average of all meningiomas, whereas that of WHO grade III meningiomas was lower.
  • When we compared the NF2 gene expression in the different meningioma grades we did not note a significant difference (P = 0.698) despite the tendency to decrease from grade I to grade III.
  • Our data supports the finding that alterations in NF2 gene alteration are histotype related but not grade related.

  • BACKGROUND: Parasagittal meningioma is one that fills the parasagittal angle, with no brain tissue between the tumor and the SSS.
  • Total RF rates were 10%, 25%, and 100% at 5 years and 100%, 50%, and 100% at 10 years for patients with meningiomas WHO grades I, II, and III, respectively.
  • The RF survival curve was better for patients with grade I meningioma (grades I vs II vs III, P = .0001).
  • There was no difference between the RF survival curves according to age, histopathologic WHO grade, location along or invasion of the SSS, and extent of resection.
  • Males (P = .0401), WHO grade I (P < .0001), total resection (P = .0139), and less sinus invasion (P = .0308) had better RFS curves.
  • CONCLUSIONS: Recurrence of parasagittal meningiomas predominated in males, in grades II/III tumors, after subtotal resection, and with more invasion of the SSS.

  • [Title] Sporadic meningioangiomatosis-associated atypical meningioma mimicking parenchymal invasion of brain: a case report and review of the literature.
  • In extremely rare condition, meningioma may occur together with meningioangiomatosis, and only 19 cases have been described in English literature until now.
  • We now report a case of meningioangiomatosis-associated meningioma with atypical and clear cell variant.
  • Microscopically, parts of lesions were atypical and clear cell meningioma corresponding to WHO grade II.
  • Neoplastic cells in atypical meningioma area were immunoreactive to epithelial membrane antigen (EMA) with high MIB-1 index of up to 20%.
  • The diagnosis of atypical meningioma associated with sporadic meningioangiomatosis was made.
  • To our knowledge, this is the first case of a meningioangiomatosis-associated meningioma with atypical and clear cell variant component to be described.
  • Meningioangiomatosis-associated meningioma is more likely to occur in younger patients and histologically to mimic parenchymal invasion of brain.
  • We suggest that postoperative radiotherapy or chemotherapy should be given careful consideration to avoid over-treatment due to erroneously interpret as malignant meningioma.

  • [Title] Sphenoid wing meningioma en plaque: report of 37 cases.
  • BACKGROUND: Sphenoid wing meningioma en plaque is a special morphological subgroup of intracranial meningiomas, defined by a carpet-like, soft tissue component that infiltrates the dura and invades the sphenoid wing and orbit associated with a significant hyperostosis.
  • This report summarized our experiences in 37 patients with sphenoid wing meningioma en plaque who had been treated with transcranio-orbital approach surgery.
  • RESULTS: Simpson grade II resection was achieved in 9 patients, Simpson grade III in 22 patients and Simpson grade IV in 6 patients.
  • CONCLUSIONS: Sphenoid wing meningioma en plaque, mainly meningothelial meningiomas, are more likely to produce adjacent hyperostosis and have characteristic radiological appearances.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • OBJECT: Despite a favorable outcome for most patients with WHO Grade I meningiomas, a subset of these patients will have recurrent or progressive disease that advances to a higher grade and requires increasingly aggressive therapy.
  • METHODS: Records of 216 patients with WHO Grade I, II, or III meningioma that were initially treated between 1965 and 2001 were retrospectively reviewed.
  • Consequently, patients with Grade I non-skull base cranial meningiomas had better 5-year recurrence-free survival (69%) than patients with Grade I skull base meningiomas (56%) or Grade II or III tumors at any site (50%; p = 0.005).
  • Unexpectedly, patients with non-skull base tumors who experienced a recurrence (8 of 22 [36%]) were more likely than patients with skull base tumors (1 of 19 [5%]) to have a higher grade tumor at recurrence (p = 0.024).
  • Furthermore, the median MIB-1 labeling index of Grade I non-skull base cranial meningiomas (2.60%) was significantly higher than that of Grade I skull base tumors (1.35%; p = 0.016).
  • CONCLUSIONS: Cranial meningiomas that occur outside of the skull base are more likely to have a higher MIB-1 labeling index and recur with a higher grade than those within the skull base, suggesting that non-skull base cranial tumors may have a more aggressive biology than skull base tumors.

  • [Title] Sstr2A immunohistochemical expression in human meningiomas: is there a correlation with the histological grade, proliferation or microvessel density?
  • In the present study, sstr2A immunohistochemical expression was analyzed in grade II and III meningiomas and was compared with that revealed in grade I meningiomas.
  • Thirty-five formalin-fixed paraffin-embedded meningiomas, comprising 13 grade I, 19 grade II and 3 grade III tumours, according to the WHO 2007 classification, were submitted to immunohistochemical assays for sstr2A.
  • Specifically, a positive staining was found in 7/13 grade I, in 16/19 grade II and in 3/3 grade III tumours, thus demonstrating that sstr2A is frequently expressed in high grade meningiomas.
  • A significantly higher microvessel density (MVD), assessed by CD105 immunostaining and Ki-67 LI were evidenced in high grade meningiomas.

  • Fifty-four formalin fixed, paraffin embedded, surgical cases of meningiomas (WHO 28 grade I and 26 grade II) as well as ten normal leptomeningeal samples were submitted to immunohistochemical analysis for CD105.
  • CD105 was not evidenced in normal samples, whereas it was demonstrated in the vessels within 14/28 WHO grade I cases and within 24/26 WHO grade II meningiomas.
  • Higher CD105 counts were significantly correlated with higher histological grade and Ki-67 LI > 4%.
  • In conclusion, our study suggests the higher specificity of CD105 in comparison to pan-endothelial markers in the evaluation of meningioma neo-angiogenesis, and its higher prognostic significance.

  • Microglial/macrophagic cells were labelled with antibodies directed against major histocompatibility complex class II, CD68, CD14 and CD163.
  • RESULTS: Twenty-five per cent (10/40) meningiomas (1/18 WHO grade II 'otherwise benign', 3/15 grade II 'otherwise atypical' and 6/7 WHO grade III) contained microglial/macrophagic cells at the tumour-brain border.
  • The presence of these cells correlated with the absence of the pial-glial basement membrane (BM) and with WHO grade III.
  • CONCLUSIONS: The immune response at the tumour-brain interface correlates with the absence of the pial-glial BM and with malignancy grade.

  • AIMS AND BACKGROUND: Meningiomas are classified following the WHO system of 2000 into three grades, benign (grade I), atypical (grade II), and anaplastic (grade III).
  • We investigated the relation between tumor grade and Ki-67 and bcl-2.
  • METHODS: In the present study, 246 cases of meningioma were reclassified according to the WHO 2000 system.
  • The relationship between tumor grade and morphological parameters like pattern, mitotic index, cellularity, pleomorphism, nucleoli, small cell population with high nucleus/cytoplasmic ratio, necrosis and brain invasion was examined.
  • There was no statistically significant difference in the prognosis between WHO grade I and grade II, whereas these two grades collectively exhibited significantly better survival than WHO grade III.
  • Ki-67 and bcl-2 expression was correlated with tumor grade, and the higher the tumor grade, the higher the Ki-67 and bcl-2 expression.
  • In conclusion, tumor grade appeared to be the most important parameter for a prognosis of meningiomas.

  • [Title] Implicating chromosomal aberrations with meningioma growth and recurrence: results from FISH and MIB-I analysis of grades I and II meningioma tissue.
  • The fluorescence in situ hybridization (FISH) technique was used in 111 WHO grades I and II meningioma patients.
  • Significant differences for MIB-1 labeling were found between grades I and II tumors (p < 0.001), and between grade I tumors that recurred and those that did not recur (p < 0.001).
  • Chromosomal aberrations were detected with FISH analysis in nearly 50% of grade I, and in 93% of grade II meningiomas.
  • The findings suggest that adding FISH analysis may allow better prediction of possible meningioma recurrence and may be a useful adjunct for therapy decisions.

  • While most are slowly growing Word Health organization (WHO) grade I tumors, rare variants (clear cell, chordoid, papillary, and rhabdoid), as well as brain invasive (WHO grade II), atypical (WHO grade II), and anaplastic (WHO grade III) meningiomas are considerably more aggressive.
  • Early stages of meningioma tumorigenesis are closely linked to inactivation of one or more members of the 4.1 superfamily, including the neurofibromatosis type 2 (NF2) and 4.1B (DAL-1) genes, which interact with the 14-3-3 protein family.
  • Other chromosome 22q genes implicated include BAM22, BCR (breakpoint cluster region), and TIMP-1, the last of which is implicated in higher-grade meningiomas.
  • The integration of histopathological appearance, complex genetic/genomic data, and outcome will likely result in the identification of clinically distinct meningioma subgroups, which in turn can facilitate the development of targeted therapeutic strategies.
