Gamma knife radiosurgery for meningiomas: a bibliometric analysis and single-center clinical trend study.

Gamma Knife radiosurgery (GKRS) is widely used for intracranial lesions, among which meningioma is one of its main indications. However, there is a lack of systematic discussion on the development trend of clinical practice and research focus. We analyzed global publishing trends and research hotspots in GKRS for meningiomas by querying the Web of Science Core Collection (English articles and reviews) and conducting bibliometric analyses with VOSviewer, CiteSpace, and Bibliometrix for data processing and visualization. At the same time, real-world clinical data from our institution were reviewed with GKRS cases from 2017 to 2024. In total, 1142 publications were included. Publishing output demonstrated a continuous growth trend, with the United States contributing the highest publication volume, and China ranking fourth. The research pattern exhibited characteristics of international collaboration and multi-institutional cooperation. At present, the focus of research is gradually turning to individualized precise treatment scheme and comprehensive prognostic follow-up strategies in GKRS for meningiomas. In parallel, our single-center cohort comprising over two thousand Gamma Knife cases showed that the proportion of meningioma treatments rose from 17.5% to 29.3% of total cases, underscoring the growing clinical adoption of this minimally invasive approach. Collectively, this study reveals significant growth and evolution in GKRS for meningiomas over the years, characterized by enhanced international collaboration and a paradigmatic shift from technical methodology toward patient-centered outcomes research. The findings provide essential guidance for future comparative effectiveness studies and evidence-based treatment protocol development.
