Hotspots and Trends in Meningioma Research Based on Bibliometrics, 2011–2021

Abstract

Meningioma, the most prevalent benign intracranial neoplasm, has been extensively studied for many years, but significant problems still exist. So far, there has been a scarcity of detailed summaries conducted to elucidate the research hotspots and future directions of meningiomas. A comprehensive search and screening strategy was employed to collect studies from 2011 to 2021 in the Web of Science Core Collection database. Thorough and systematic co-authorship and co-occurrence keyword maps were generated, and statistics tables summarizing countries, organizations, authors, and keywords were created. A total of 1544 articles meeting the screening criteria were collected. The results indicated that the United States, Germany, and China produced the highest number of publications from 2011 to 2021, with 586, 244, and 197 records, respectively. The cooperation networks also mainly revolved around these three countries, particularly the United States. The keyword with the most frequency was "surgery", followed by "recurrence" and "management", with the frequencies of 248, 212, and 163, respectively. The most prominent cluster during the last decade was #0 methylation cluster and serveral keywords like "survival", "brain invasion", and "magnetic resonance imaging" exhibited significant burst strength. This study aims to provide a comprehensive analysis that evaluated the research landscape and identifies potential research directions. The findings of our study disclosed productive individuals and institutions. The current research focuses on the molecular pathology of meningiomas, improvements in techniques, and advancements in MRI diagnosis. Especially the molecular pathology improvement might lead the future research directions.
