  • 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.

Espinosa AB, Tabernero MD, Maíllo A, Sayagués JM, Ciudad J, Merino M, Alguero MC, Lubombo AM, Sousa P, Santos-Briz A, Orfao A: The cytogenetic relationship between primary and recurrent meningiomas points to the need for new treatment strategies in cases at high risk of relapse.

  • PURPOSE: Recurrence is the major factor influencing the clinical outcome of meningioma patients although the exact relationship between primary and recurrent tumors still needs to be clarified.
  • EXPERIMENTAL DESIGN: Multicolor interphase fluorescence in situ hybridization was done for the identification of numerical abnormalities of 12 chromosomes in single-cell suspensions from 59 tumor samples corresponding to 25 recurrent meningioma patients.
  • Multivariate analysis of prognostic factors showed that the Maillo et al. prognostic score, based on age of patient, tumor grade, and monosomy 14, together with tumor size was the best combination of independent variables for predicting tumor recurrence at diagnosis.
  • CONCLUSION: Overall, our results indicate that the development of recurrent meningiomas after complete tumor resection is usually due to regrowth of the primary tumor and rarely to the emergence of an unrelated meningioma, underlining the need for alternative treatment strategies in cases at high risk of relapse, particularly those with a high Maillo et al. prognostic score and larger tumors.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • RESULTS: In the group of 33 patients with histologically verified grade 1 meningiomas, the mean absolute growth rate was 1.51 cm (3)/year, the median relative growth rate and tumor doubling time was 14.18 %/year and 5.228 years.
  • In atypical meningiomas (WHO grade 2), absolute and relative growth rates were significantly higher and tumor doubling times shorter.
  • CONCLUSION: The majority of intracranial meningiomas are slow growing tumors, although the growth rates may vary widely even among benign grade 1 meningiomas.

  • Rhabdoid meningioma is an uncommon variant of meningioma, and was classified separately for the first time in the 2000 World Health Organization's classification of tumors of the nervous system.
  • Because it often shows malignant histological features and follows an aggressive clinical course, it has been classified as a grade III neoplasm.
  • From 13 patients (seven male, six female), 19 specimens of rhabdoid meningioma were obtained between 2001 and 2009.

  • OBJECTIVE: To investigate the respective role of fractionated radiotherapy (FR) and gamma knife stereotactic (GKS) radiosurgery in cavernous sinus meningioma (CSM) treatment.
  • According to Sekhar's classification, 26 (68.4%) patients were Grade III to IV in Group I and 10 (27.8%) patients in Group II (P < 0.05); 23 (60.5%) patients had extensive lesions in Group I and 7 (19.4%) patients in Group II (P < 0.05).
  • Therefore, in the authors' opinion, GKS radiosurgery should be advocated in first intention for patients with CSMs, whereas conventional radiotherapy should be reserved for cases that are not amenable to this technique, thus making these two therapeutic modalities not alternative but complementary tools in CS meningioma treatment strategy.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • METHODS AND RESULTS: Immunohistochemical analysis revealed lack of E-cadherin expression at the cell membrane in 34% of meningiomas independent of their WHO grade.
  • Both immunofluorescence and Western blot analysis of fractionated meningioma cells located beta-catenin mostly on the Golgi apparatus and ER/Golgi intermediate compartment (ERGIC).
  • CONCLUSIONS: The lack of membranous beta-catenin and/or membranous E-cadherin in meningiomas may indicate an altered interaction between meningioma cells independent of loss of NF2 and independent of the tumour grade.

  • [Title] Genetic polymorphisms of glutathione S-transferases and the risk of adult brain tumors: a meta-analysis.
  • BACKGROUND: Studies investigating the association between genetic polymorphisms of glutathione S-transferases (GST) and risk of adult brain tumors have reported conflicting results.
  • The rationale of this meta-analysis was to determine whether GST variants increase the susceptibility of adult brain tumors by pooling data.
  • Papers were included if they were observational studies investigating the influence of GSTM1, GSTT1, GSTP1 I105V, or GSTP1 A114V on the development of adult brain cancers.
  • RESULTS: We identified eight eligible studies, which included 1,630 cases of glioma, 245 cases of meningioma, and 7,151 controls.
  • Subgroup analyses also showed no relationship between GST variants and histopathologic groups; the overall ORs were 1.13 (95% CI, 0.88-1.43) for high-grade glioma and 1.08 (95% CI, 0.76-1.55) for low-grade glioma.
  • The T1 null genotype was significantly associated with a risk of meningioma (OR, 1.95; 95% CI, 1.02-3.76), but the M1 variant was not.
  • CONCLUSION: This study did not suggest any relationship between GST variants and risks of glioma; the T1 null genotype may influence the susceptibility of meningioma, but larger studies are needed to substantiate this relationship.

  • [Title] A multivariate analysis of prognostic factors for health-related quality of life in patients with surgically managed meningioma.
  • The objective of this study was to examine the prognostic significance of health-related quality of life (HQOL) parameters combined with baseline clinical factors in patients undergoing neurosurgery for treatment of meningioma.
  • A total of 147 patients (61 male, 86 female; mean age 43 years, range 5-77 years) who underwent resection of a meningioma between January 2002 and December 2004 were studied.
  • The relationships between HQOL and clinical history, radiological findings, extent of resection, histological grade and recurrence were investigated using multivariate analysis.
  • The mean HQOL score was 73.94+/-1.79 for preoperative patients with meningioma, 84.88+/-2.14 for postoperative patients, and 91.13+/-1.61 for healthy controls.
  • HQOL for patients with meningioma was significantly lower than that for normal controls (P<0.001), and postoperative patients had a more satisfactory HQOL than preoperative (P<0.05).
  • Cox proportional hazards analysis showed that significant predictors of health-related quality of life were tumor size, extent of surgical excision, and histologic grade.
  • Multivariate backward logistic regression yielded the regression equation HQOL=119.1097 - 1.5002X(3) - 8.6650X(6) - 10.4210X(7) (R=0.7466; where X(3) is tumor size, X(6) is extent of surgical excision, and X(7) is the histologic grade of the tumor).
  • This equation can be used preoperatively to predict the HQOL of meningioma patients after neurosurgery.
  • A specialized HQOL questionnaire for patients with meningioma provides useful information when planning the operative procedure, and may make it more likely that patients have a satisfactory HQOL after surgery.

  • PURPOSE: Meningiomas are the most common extraaxial intracranial type of tumor, and their management and prognosis depend on their grade and histology.
  • The aim of the present study was to assess the role of diffusion and diffusion tensor metrics in the identification and classification of meningioma grades and subtypes.
  • METHODS AND MATERIALS: A total of 21 consecutive patients with meningioma were included in this retrospective study, of whom 16 had benign meningiomas (three fibroblastic, 11 transitional/mixed, two meningothelial) and five had atypical meningiomas.

  • MRI demonstrated a T4-5 intradural mass ventral to the spinal cord, with an enhancing dural tail, consistent with meningioma.
  • Intermediate grade melanocytomas (IMGs) are the least common variant, comprising about 10% of PMMTs reported.
  • For primary CNS melanocytic neoplasms, complete tumor resection is preferred, as it leads to cure of well-differentiated and intermediate-grade melanocytomas and most melanomas.
  • Radiotherapy is recommended for incomplete resection of IMGs and melanomas; the recurrence potential of low-grade melanocytomas is less clear and watchful waiting may be employed, since recurrent tumors may be treated surgically prior to radiation.

  • The results from 57 brain tumor cases demonstrated that, for grade IV gliomas only, decreases in the BOLD fMRI activation volumes within the ipsilateral PMC, when compared with that observed in the contralateral PMC, correlated with increases in the relative regional cerebral blood volume (rCBV) in the PMC.
  • In addition, relative increases in the activation volumes, corresponding to decreases in the rCBV, exhibited a linear dependence on the distance between the grade IV glioma and PMC.
  • The nature of the relationship between the resulting activation volumes and adjacent tumor characteristics is complex, but is found to be dependent on the tumor grade and type, as well as the distance of the tumor to the PMC.

  • Radiation therapy remains a critical therapeutic modality in the treatment of adult brain tumors.
  • In high-grade gliomas, current trials focus on the addition of systemic agents and optimization of target delineation to improve the therapeutic ratio of radiotherapy.
  • In low-grade gliomas, the life expectancy is much greater, and the possibility of late effects of radiotherapy have shaped contemporary trials to attempt to identify groups that benefit from radiotherapy versus the ones that may defer radiotherapy until tumor progression.
  • With meningioma, the use of normal tissue-sparing techniques such as radiosurgery has allowed for the successful treatment of patients who are eminently curable and with a life expectancy that is generally no different than that of the general population.

  • OBJECTIVE: To evaluate a possible association of glioma or meningioma with use of cellular telephones, using a nationwide population-based case-control study of incident cases of meningioma and glioma.
  • METHODS: The authors ascertained all incident cases of glioma and meningioma diagnosed in Denmark between September 1, 2000, and August 31, 2002.
  • They enrolled 252 persons with glioma and 175 persons with meningioma aged 20 to 69.
  • Use of cellular telephone was associated with a low risk for high-grade glioma (OR, 0.58; 95% CI, 0.37 to 0.90).
  • The risk estimates were closer to unity for low-grade glioma (1.08; 0.58 to 2.00) and meningioma (1.00; 0.54 to 1.28).
  • CONCLUSION: The results do not support an association between use of cellular telephones and risk for glioma or meningioma.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • PURPOSE: To prospectively assess if diffusion-weighted MR imaging (DWI) could be used to differentiate between different types of brain tumors and to distinguish between peritumoral infiltration in high-grade gliomas, lymphomas, and pure vasogenic edema in metastases and meningiomas.
  • MATERIAL AND METHODS: MR imaging and DWI was performed on 93 patients with newly diagnosed brain tumors: 59 patients had histologically verified high-grade gliomas (37 glioblastomas multiforme, 22 anaplastic astrocytomas), 23 patients had metastatic brain tumors, five patients had primary cerebral lymphomas, and six patients had meningiomas.
  • ADC values and ratios of high-grade gliomas, primary cerebral lymphomas, metastases, and meningiomas were compared by using ANOVA and multiple comparisons.
  • Optimal thresholds of ADC values and ADC ratios for distinguishing high-grade gliomas from metastases were determined by receiver operating characteristic (ROC) curve analysis.
  • RESULTS: Statistically significant differences were found for minimum and mean of ADC tumor and ADC tumor ratio values between metastases and high-grade gliomas when including only one factor at a time.
  • CONCLUSION: Our results suggest that ADC values and ADC ratios (minimum and mean of ADC tumor and ADC tumor ratio) may be helpful in the differentiation of metastases from high-grade gliomas.
  • It cannot distinguish high-grade gliomas from lymphomas, and lymphomas from metastases.
  • ADC values and ADC ratios in peritumoral edema cannot be used to differentiate edema with infiltration of tumor cells from vasogenic edema when measurements for high-grade gliomas, lymphomas, metastases, and meningiomas were compared.

  • Chordomas and low-grade chondrosarcomas of the central nervous system share many histological features, generating, at times, considerable diagnostic difficulty and, not infrequently, requiring immunohistochemical analysis for appropriate classification.
  • We found that D2-40 robustly and reliably immunostains low-grade chondroid neoplasms (100% of enchondromas and 94% of grades I and II chondrosarcomas), but not chordomas.
  • By contrast, we observed generally strong and diffuse cytokeratin positivity in all cases of chordoma, but not in cases of enchondroma or low-grade chondrosarcoma.
  • We also demonstrate D2-40 immunoreactivity in two cases of chordoid meningioma and, in doing so, tentatively provide a means to distinguish this tumor from chordoma.

  • However, the expression of seven 14-3-3 isoforms in meningioma still remains unknown.
  • This study is the first examination of 14-3-3 isoforms in three grades of meningioma by immunohistochemistry.
  • 14-3-3epsilon, zeta and theta were specifically expressed in meningioma, and their expression levels increased with the increase of pathological grade of meningioma.
  • The 14-3-3 eta, beta, gamma and sigma isoforms were negatively expressed in meningioma.
  • In conclusion, The 14-3-3 epsilon, zeta and theta may be involved in tumorigenesis of meningioma and be efficient markers for predicting the degree of malignancy in meningioma.

  • [Title] WHO grade II and III meningiomas: a study of prognostic factors.
  • 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.
  • Prospective trials should delineate strong therapeutic guidelines for high-grade meningiomas.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • In the present study we aimed at determining the relationship of basement membrane intactness and SPARC protein expression at the meningioma-brain border.
  • Sections of 51 brain-invasive meningiomas (31 meningothelial meningiomas WHO grade I, 11 atypical WHO grade II, and nine anaplastic WHO grade III tumours) were immunolabelled with antibodies against SPARC, epithelial membrane antigen (EMA), collagen IV and glial fibrillary acidic protein (GFAP).
  • Twenty-two non-invasive WHO grade I meningothelial meningiomas were included in the study for comparison.
  • By contrast, the number of WHO grade I tumours expressing collagen IV (15/31) was highly significantly elevated when compared with WHO grade II (1/11) and WHO grade III (0/9) (both P < 0.0001).
  • In conclusion, the destruction of the basement membrane is correlated with meningioma malignancy grade whereas the expression of SPARC protein at the tumour-brain border is not.

  • OBJECTIVE AND IMPORTANCE: We present a rare case of very long-term medulloblastoma relapse in an adult patient and discuss the pattern of recurrence and metabolic imaging of the tumor.
  • Magnetic resonance images were suggestive of a meningioma.
  • Several hypotheses were discussed, such as other radio-induced tumors, sarcomas, high-grade gliomas, or lymphomas (previous chemotherapy) and even recurrence of medulloblastoma.
  • Metabolic imaging favored the diagnosis of medulloblastoma over the initially suspected diagnosis of meningioma.

  • 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.
  • Of these samples, 455 were benign (WHO Grade I), 49 atypical (Grade II), and 6 malignant (Grade III).
  • 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).
  • CONCLUSIONS: Carbonic anhydrase II positivity in the endothelium was associated with cell proliferation and malignancy grade.

  • 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.
  • 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.

  • OBJECT: The aim of this study was to estimate the accuracy of routine magnetic resonance (MR) imaging studies in the classification of brain tumors in terms of both cell type and grade of malignancy.
  • In routine reporting of MR imaging examinations, tumor types and grades were classified with a high specificity (85.2-100%); sensitivity varied, depending on the tumor type and grade, alone or in combination.
  • The recognition of broad diagnostic categories (neuroepithelial or meningeal lesions) was highly sensitive, whereas when both detailed type and grade were considered, sensitivity diverged, being highest in low-grade meningioma (sensitivity 100%, 95% CI 96.2-100.0%) and lowest in high-grade meningioma (sensitivity 0.0%, 95% CI 0.0-65.8%) and low-grade oligodendroglioma (sensitivity 15%, 95% CI 5.2-36.0%).
  • In neuroepithelial tumors, sensitivity was inversely related to the precision in reporting of grade and cellular origin; "glioma" was a frequent neuroimaging classification associated with higher sensitivity in the corresponding category.
  • This study targets the need for noninvasively increasing sensitivity in categorizing most brain tumor types while retaining high specificity, especially in the differentiation of high- and low-grade glial tumor classes.

  • The bright signals were interpreted as showing multifocal hemorrhage and the mass was felt to be a convexity meningioma.
  • Rare convexity osteochondromas may be mistaken for high-grade meningiomas on neuroimaging studies; their avascular nature, coupled with their complex signal pattern can serve as clues to the correct pre-operative diagnosis.

  • BACKGROUND: We retrospectively analyzed a series of patients harboring a FT meningioma with regard to clinical presentation, surgical technique, and follow-up results.
  • METHODS: Clinical data in a consecutive series of 13 patients treated for a meningioma of the FT junction were retrospectively reviewed.
  • The main surgical approach to the meningioma was via an occipital interhemispheric route (10 patients).
  • A complete resection (Simpson grade 1 and 2) was achieved in 85% of patients.
  • One tumor recurrence in an atypical meningioma was observed after the mean follow-up period of 6.2 years (range, 1-14 years) with clinical and MRI examination and had to be reoperated.

  • To investigate the molecular mechanisms of meningioma formation, the expression profiles of 12 000 genes from meningiomas and dural specimens were compared.
  • METHODS: Ribonucleic acid from 6 meningiomas (World Health Organization Grade I) and 4 dural specimens was profiled using U95A GeneChips (Affymetrix, Inc., Santa Clara, CA).
  • Function and methylation of DLC1 were assessed by ectopic expression in 5 primary cultures, demethylation assay using 5-aza-2'-deoxycytidine, and methylation-specific polymerase chain reaction in 4 meningioma samples.
  • Although demethylation decreased meningioma cell growth rates in vitro, methylation-specific polymerase chain reaction did not detect DLC1 promoter methylation.

  • BACKGROUND: An association between meningioma, breast cancer, and increased growth of meningiomas during pregnancy, and the luteal phase of the menstrual cycle have been shown in previous reports, but the mechanisms still remain unclear.
  • METHODS: We described 3 patients with meningioma who presented during the early postpartum period.
  • RESULTS: Pathologic studies of tumor specimens revealed atypical meningioma (grade 2), syncytial meningioma (grade 1), and transitional-psammomatous meningioma (grade 1), for cases 1, 2, and 3, respectively.
  • CONCLUSIONS: Although many reports indicating an association between meningioma and pregnancy have been published, the number of immunohistochemical studies is limited.

  • 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.

  • [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.

  • Meningiomas are extremely common adult brain tumors originating from meningeal coverings of the brain and spinal cord.
  • 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.

  • [Title] Pattern of relapse after fractionated external beam radiotherapy for meningioma: experience from Addenbrooke's Hospital.
  • AIMS: Radiotherapy is an important treatment modality for meningioma.
  • We aimed to review the clinical outcomes for meningioma patients treated with radiotherapy in the Addenbrooke's Hospital Oncology Department.
  • MATERIALS AND METHODS: A retrospective chart review was carried out on patients with meningioma referred and treated in the department between 1 November 1996 and 31 October 2006.
  • Overall survival was 78% at the time of follow-up, with death related to meningioma in 7% of the total cohort.
  • Local control was 85% overall, 93% for grade 1 disease, 45% for grade 2 disease and 82% for grade 3 disease.
  • Patients with non-benign disease were more likely to receive >50Gy (27% of grade 1 lesions vs 65% of grade 2/3 lesions), but despite this local control remained poor, even with the higher dose delivered (local control 60 and 40% for grade 2 lesions treated with 50 and >50Gy, respectively, and 100 and 75% for grade 3 lesions treated with 50 and >50Gy, respectively).
  • Grade was an important prognostic factor.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • 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).
  • 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] 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] Clinicopathologic and genetic profile of intracranial marginal zone lymphoma: a primary low-grade CNS lymphoma that mimics meningioma.
  • PURPOSE: Although rare overall, marginal zone B-cell lymphoma (MZBCL) is the most common primary low-grade CNS lymphoma reported in the literature.
  • RESULTS: CNS MZBCLs preferentially affect middle-aged women (female-to-male ratio, 4:1), with 93% presenting as dural-based masses mimicking meningioma.
  • CONCLUSION: Our data suggest that intracranial MZBCL is an indolent primary CNS lymphoma that typically presents as a meningioma-like dural-based mass.

  • 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] 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.

  • They have a wide range of histopathological appearances and are classified, according to the aggressiveness of their growth and the risk of recurrence, as WHO grade I (benign) meningiomas, WHO grade II (atypical) meningiomas and WHO grade III anaplastic (malignant) meningiomas.
  • The expression of cathepsins B and L and their inhibitors stefin B and cystatin C in 21 benign (grade I) and 9 atypical (grade II) meningiomas has been compared by immunohistochemical staining, QRT-PCR and Northern blot analysis.
  • The expression of cathepsins and inhibitors was not different between central and peripheral meningioma tissue or between histological subtypes of meningiomas, with the exception of cathepsin L, the level of which was significantly lower in transitional meningiomas.
  • The diagnostic and prognostic value for relapse of meningioma needs to be confirmed in a larger population of patients.
