Ewing sarcoma: what trends in recent works? A holistic analysis with global productivity: A cross-sectional study

Advances in the biology of Ewing sarcoma, which continues to be an important cause of mortality, have caused an increase in information in the literature related to the underlying molecular base of the disease and discussions of new treatment approaches. In this study, we aimed to comprehensively analyze the published scientific articles on Ewing sarcoma. The Web of Science database was used to obtain and statistically analysis articles on Ewing sarcoma that were published between 1980 and 2021. Maps of network visualization were used to reveal trending topics, global collaborations, and the most effective studies. Correlation analysis was performed using Spearman's correlation coefficient. A total of 3236 articles were analyzed. The first 3 countries that contributed the most to the literature and cooperated most intensively were USA (1194, 36.8%), Germany (293, 9%), Italy (254, 7.8%). Pediatric Blood & Cancer (n = 122), Cancer (87), Journal of Pediatric Hematology Oncology (71) were among the top 3 journals with the most articles. The most active author was Piero Picci (n = 94). High-income countries have a great effect on the literature on this subject. The most studied trend topics in recent years were pediatric oncology, EWS RNA Binding Protein 1 (EWSR1), EWSR1-FL1, epigenetics, bioinformatics, microRNA, gene expression, metastasis, migration, biomarker, immunotherapy, survival, outcomes, surveillance epidemiology and end results (SEER), nomogram, temozolomide, irinotecan, and drug resistance. Genetic studies, metastasis, immunotherapy, life analyses/nomogram based on new data obtained from SEER, and chemotherapy with irinotecan and temozolomide combination, were seen to be the topics researched in recent years.
