Understanding the natural course of meningiomas is important to provide appropriate treatment. The majority of previous studies investigated factors related to their growth, but failed to demonstrate their relationship with symptomatic progression (sympP) because of its rarity. We reviewed and meta-analyzed 27 studies that investigated natural courses in asymptomatic or untreated meningiomas to find clinico-radiological factors predictive of radiological progression (radioP), growth speed, and sympP. In results of time-growth analysis, two-thirds of meningiomas showed radioP defined by a volume criterion and the rate approached a plateau at 4-5 years. In growth curve analyses, about half of incidental meningiomas presented decelerating or no growth, while less than one-quarter of them grew exponentially. RadioP, growth speed [annual volume change (AVC) or relative growth rate], and sympP each had different factors related to them. Younger age, non-calcification, and high intensity on T2-weighted image were related to radioP and rapid growth speed, but not to sympP. Tumors in males and those of larger size were likely to be symptomatic in the meta-analysis. AVC (≥2.1 cm3/year) was the strongest indicator of sympP. Apart from perifocal edema, radiological features at up-front imaging may not be useful for predicting sympP. This may be due to dynamic changes of those radiological markers in the long term. Quantified tumor size and growth speed, especially AVC, are important markers for deciding on treatment.","subitem_description_type":"Abstract"}]},"item_4_description_42":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Journal Article","subitem_description_type":"Other"}]},"item_4_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本脳神経外科学会"}]},"item_4_publisher_34":{"attribute_name":"別言語の出版者","attribute_value_mlt":[{"subitem_publisher":"Japan Neurosurgical Society"}]},"item_4_relation_10":{"attribute_name":"PubMed番号","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"32009127","subitem_relation_type_select":"PMID"}}]},"item_4_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.2176/nmc.ra.2019-0213"}],"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.2176/nmc.ra.2019-0213","subitem_relation_type_select":"DOI"}}]},"item_4_relation_13":{"attribute_name":"PMCID","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"PMC7073704"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7073704/","subitem_relation_type_select":"URI"}}]},"item_4_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2020 by The Japan Neurosurgical Society"}]},"item_4_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-8029","subitem_source_identifier_type":"ISSN"}]},"item_4_version_type_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"NAKASU, Satoshi"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"NAKASU, Yoko"}],"nameIdentifiers":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-04-20"}],"displaytype":"detail","filename":"nmc.ra.2019-0213.pdf","filesize":[{"value":"730.4 kB"}],"format":"application/pdf","license_note":"This article is licensed under a Creative Commons [Attribution-NonCommercial-NoDerivatives 4.0 International] license.\nhttps://creativecommons.org/licenses/by-nc-nd/4.0/","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"nmc.ra.2019-0213","url":"https://shiga-med.repo.nii.ac.jp/record/3519/files/nmc.ra.2019-0213.pdf"},"version_id":"03780feb-1601-4b43-a05c-dc7a06ab99b3"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"growth curve","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"growth rate","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"incidental meningioma","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"natural history","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"volumetry","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Natural History of Meningiomas: Review with Meta-analyses.","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Natural History of Meningiomas: Review with Meta-analyses."}]},"item_type_id":"4","owner":"11","path":["231"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-04-20"},"publish_date":"2020-04-20","publish_status":"0","recid":"3519","relation_version_is_last":true,"title":["Natural History of Meningiomas: Review with Meta-analyses."],"weko_creator_id":"11","weko_shared_id":-1},"updated":"2023-06-19T12:20:50.536096+00:00"}
