Bibliometric analysis of bone metastasis from prostate cancer research from 2007 to 2024

Prostate cancer (PCa) is one of the most common cancer in men worldwide, while numerous scientific achievements have been made in research on Bone metastasis in prostate cancer (BMPCa) in recent years, a comprehensive and objective bibliometric analysis remains absent. This study aimed to elucidate the overall literature distribution and international frontier research direction of BMPCa.

A comprehensive bibliometric analysis was conducted on relevant literature on BMPCa extracted from the Web of Science database from 2007 to 2024 by Microsoft Office Excel, Biblioshiny, Scimago Graphica, VOSviewer and CiteSpace. 5512 papers related to BMPCa were extracted from the Web of Science Core Collection (WoSCC). The number of publications, countries, institutions, global collaborations, authors, journals, keywords, thematic trends, and cited references were then visualized. Finally, the research status and development direction were analyzed.

This study included a total of 5512 papers on BMPCa from 2007 to 2024. There has been a steady increase in global publications ever year, peaking in 2021,and the overall publication shows a linear growth trend. USA had the highest number of publications and collaborative efforts, followed by China, England. The University of Texas MD Anderson Cancer Center published the most articles with 173, followed by University of Michigan with 120 and Memorial Sloan Kettering Cancer Center with 114. Prostate had the highest number of publications. The top three high-frequency keywords of occurrence were "prostate cancer", "bone metastasis" and "bone metastases", biblioshiny analysis of keywords shows that "arificial intelligence", "machine learning", and "ga-68"may represent the frontiers of this research area.

The results showed that a linear growth trend in the number of publications, and the United States has made significant contributions to BMPCa both in quantity and in collaboration. International cooperation in BMPCa research needs to be further strengthened. We hope that more researchers and organizations can promote academic exchanges and strengthen cooperation to continue addressing the gaps of BMPCa. Further research should focus on the pathogenesis, early prevention, and the integration of individualized treatment with artificial intelligence, in order to improve patient survival and quality of life.
