Bibliometric analysis of Ewing sarcoma from 1993 to 2022

Abstract

Abstract Background Ewing sarcoma has attracted more attention in recent years but has yet to be bibliometrically analyzed. Hence, this study investigated the trend of Ewing sarcoma over the past 30 years with bibliometric analysis. Methods Original publications related to Ewing sarcoma were obtained from the Science Citation Index Extension (SCI-E), Social Sciences Citation Index (SSCI), and Web of Science Core Collection (WoSCC) between 1993 and 2022. CiteSpace and VOSviewer were used to extract the countries/regions, institutions, authors, journals, references, and keywords involved in this topic to identify and analyze the research hotspots and trends in this field. Results Over the past 30 years (especially in the past five years), the number of articles published on Ewing sarcoma continued to increase, and the most published country was the United States of America (USA). High-frequency keywords included "Ewing sarcoma", "tumor", "family", "bone", "chemotherapy", "expression", "primitive neuroectodermal tumor", "prognostic factors", "children", and "survival rate". According to the analysis of keyword saliency of Ewing sarcoma, we found that "chromosome translocation", "intergroup", "sarcoma", "genomic landscape", and "children oncology group" were emerging research hotspots. The timeline of the cluster map of co-cited literature indicated that the treatment of Ewing sarcoma emerged as a research hotspot. Conclusion Researchers' understanding of Ewing sarcoma has improved dramatically over the past 30 years. At present, the research hotspots of Ewing sarcoma mainly focus on the aspects of "chromosome translocation", "intergroup", and "sarcoma". In addition, the timeline of the cluster map of co-cited literature indicated the emergence of the treatment of Ewing sarcoma as a research hotspot.
