A bibliometric analysis of research trends and hotspots of pilocytic astrocytoma from 2004 to 2023

Resumen

Pilocytic astrocytoma (PA) is a WHO grade I neoplasm with a favorable prognosis. It is the most common pediatric benign tumor. Recently, PA has attracted more and more attention and discussion from scholars. The aim of this study is to comprehensively generalize the evolution of this field over the past two decades through bibliometric analysis and to predict future research trends and hotspots. The literature over the last two decades (2004–2023) related to PA was obtained from the Web of Science Core Collection (WoSCC) database. Bibliometric analyses were conducted based on the following aspects: (1) Annual publication trends; (2) Publications, citations/co-citations of different countries/institutions/journals/authors; (3) the map of Bradford’s Law and Lotka’s Law for core journals and author productivity; (4) Co-occurrence, cluster, thematic map analysis of keywords. All analyses were performed on VOSviewer and R bibliometrix package, and Excel 2024. Our results showed that research on PA displayed a considerable development trend in the past 20 years. The USA had a leading position in terms of scientific outputs and collaborations. Meanwhile, German Cancer Research Center contributed the most publications. Child’s Nervous System had the highest number of publications and Acta Neuropathologica was the most co-cited journal on this subject. Gutmann, D.H. and Louis, D.N. were the authors with the most articles and co-citations in this field. The research emphases were molecular mechanisms, neurofibromatosis, pilomyxoid astrocytoma, differential diagnosis, and therapy. We systematically analyzed the literature on PA from a bibliometric perspective. The demonstrated results of the knowledge mapping would provide valuable insights into the global research landscape.
