Abstract
BACKGROUND Multiple meningiomas (MMs) rarely occur sporadically. It is unclear whether each individual tumor in a single patient behaves similarly. Moreover, the molecular mechanisms underlying the formation of sporadic MMs and clonal formation etiology of these tumors are poorly understood. METHODS Patients with spatially separated MMs without prior radiation exposure or a family history who underwent surgical resection of at least two meningiomas were included. Unbiased, comprehensive next generation sequencing was performed, and relevant clinical data was analyzed. RESULTS Fifteen meningiomas and one dural specimen from six patients were included. The majority of tumors (12/15) were WHO Grade I; one patient had bilateral MMs, one of which was Grade II, while the other was Grade I. We found 11/15 of our cohort specimens were of NF2-loss subtype. Meningiomas from 5/6 patients had a monoclonal origin, with the tumor from the remaining patient showing evidence for independent clonal formation. We identified a novel case of non-NF2 mutant MM with monoclonal etiology. MMs due to a monoclonal origin did not always display a homogenous genomic profile, but rather exhibited heterogeneity due to branching evolution. CONCLUSIONS Both NF2-loss and non-NF2 driven MMs can form due to monoclonal expansion and those tumors can acquire inter-tumoral heterogeneity through branched evolution. Grade I and II meningiomas can occur in the same patient. Thus, the molecular make-up and clinical behavior of one tumor in MMs, cannot reliably lend insight into that of the others and suggests the clinical management strategy for MMs should be tailored individually.

NMC Case Rep J 2021; 8:215-220. [PMID: 35079466 PMCID: PMC8769410 DOI: 10.2176/nmccrj.cr.2020-0159] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2020] [Accepted: 09/03/2020] [Indexed: 12/02/2022] Open
Abstract
Meningiomas are the most common intracranial primary neoplasm in adults, and show
various histological subtypes, indicating heterogeneous clinical and molecular
genetic characteristics. Different subtypes of meningioma coexisting
independently within the main tumor of another different subtype is a quite rare
clinical situation. A 69-year-old woman presented with a several- year history
of dizziness as a non-specific complaint. Magnetic resonance imaging (MRI)
revealed an extra-axial mass lesion in the left parieto-occipital region
including two well-demarcated, round mass components. Total resection was
performed via left parieto-occipital craniotomy. Two white masses were
identified within the main tumor, with neither showing dural attachments.
Pathological findings showed the main mass represented meningothelial meningioma
and the demarcated mass lesions were both fibrous meningiomas. No transitional
features existed between these subtypes. No differences in genetic
characteristics were evident between subtypes of meningioma. We have described,
apparently for the first time, a case of two fibrous meningiomas coexisting in
an isolated manner in meningothelial meningioma with the similar molecular
genetic profile.

Sheng HS, Shen F, Zhang N, Yu LS, Lu XQ, Zhang Z, Fang HY, Zhou LL, Lin J. Whole exome sequencing of multiple meningiomas with varying histopathological presentation in one patient revealed distinctive somatic mutation burden and independent clonal origins. Cancer Manag Res 2019; 11:4085-4095. [PMID: 31123420 PMCID: PMC6510395 DOI: 10.2147/cmar.s202394] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2019] [Accepted: 03/21/2019] [Indexed: 12/20/2022] Open
Abstract
Background: Although meningiomas are common intracranial tumors, multiple meningiomas (MMs) are rare entities in patients without neurofibromatosis type 2. Previous studies suggest most sporadic MMs are of monoclone in origin. Objective: To elucidate the clonal relationship between two sporadic meningiomas from the same patient by using the next-generation sequencing (NGS) platform. Methods: Two MMs, located frontally and parietally on the right side, were surgically removed from a 52-year-old male. Pathological examinations and whole exome sequencing were performed on tumor samples, followed by Sanger sequencing validation. Results: MMs were diagnosed as secretory and fibrous subtypes, respectively, on histology (WHO grade I) and tumor DNA exhibited distinctive somatic mutation patterns. Specifically, the secretory subtype carried more single nucleotide variant while the fibrous subtype had much higher copy number variation. Besides, the two tumors demonstrated different mutation profiles in predisposing genes and known driver mutations. For example, the secretory subtype had missense mutations in TRAF7 and KLF4, while the fibrous subtype had frameshift deletion of NF2 gene in addition to copy number loss of NF2 and SMARCB1, genetic events that have already been associated with the development of meningiomas. Significantly mutated gene analysis revealed novel mutations of LOC729159 in the secretory subtype and RPGRIP1L and DPP6 in the fibrous subtype. Sanger sequencing validated important point mutations in TRAF7 (c.1678G>A, p.G560S), KLF4 (c.1225A>C, p.K409Q) and CDH11 (c.169T>G, p.W57G). Conclusion: Our data suggest the two meningiomas might develop independently in this patient and molecular subtyping by NGS is a valuable supplement to conventional pathology. Further study is needed to ascertain whether these novel genetic events are tumorigenic or simply passenger mutations, as well as their clinical implications.
