BIBLIOMETRIC ANALYSIS OF THE SCIENTIFIC LITERATURE ON MENINGIOMAS WITH CALCIFICATION

Abstract

Meningiomas are the most common non-glial tumours of the central nervous system characterized by pathological biomineralization. The work aimed to conduct bibliometric analysis and systematize data on the prevalence, etiology, morphology and main trends in the study of meningiomas with calcification. The authors searched for information on meningiomas in electronic databases such as PubMed, Scopus, Web of Science and Google Scholar for the past 25 years by the key terms such as meningiomas, calcifications, and psammoma bodies. For bibliometric analysis, the authors used an online platform to monitor and analyze international research using visualization tools and modern citation metrics SciVal (Scopus) and a tool for building and visualizing bibliometric networks VOSviewer. Pathological biomineralization is manifested through the formation of psammoma bodies, and the main mineral component is calcium hydroxyapatite. Although calcification is likely to play a protective role and be a favourable prognostic feature, it should be considered when choosing surgical tactics. There is also the problem of closing the defects of the dura mater with the help of biological and synthetic transplants. According to the bibliometric analysis of scientific literature on meningiomas and the phenomena of pathological biomineralization in them, we found that the number of publications on this topic had increased significantly over the past five years, the leading countries of origin are the United States, Japan and China. When researching the array of Scopus database publications using SciVal tools, the problem of meningioma calcification was divided into 61 topics and 24 thematic clusters, the vast majority of which belonged to medicine and biology and materials science. According to the results of bibliometric analysis of 678 publications in the Scopus database by keywords "calcification" and "meningioma", they can be divided into seven thematic clusters and four chronological stages. Despite the prevalence of meningioma calcification, there is currently no fundamental idea of ​​the etiology and pathogenesis of this process. Studying the morphological features of meningiomas with calcification can help improve the diagnosis and treatment of the central nervous system tumours.
