This study examines radiotherapy article representation in leading journals and compares their frequency and bibliometric profile with three other cancer treatment modalities. Material/Methods: The ten highest-ranked general medicine journals were identified using CiteScore 2024. PubMed was searched for articles indexed with the MeSH term “Radiotherapy” as a Major Topic, restricted to these journals, for the years 2000–2024, and with available abstracts. Editorials, letters, commentaries, and historical articles were excluded. The same strategy was applied to “Immunotherapy,” “Antineoplastic Agents, Hormonal,” and “Minimally Invasive Surgical Procedures.” Only articles related to the treatment of neoplasms were included. For radiotherapy, bibliometric parameters included journal, open access status, co-author number, international collaboration, affiliation, country and gender of the corresponding author, study type, and frequent terms in abstracts and keywords. Data extraction was completed on 8 October 2025 and analyzed using Biblioshiny and Excel. Results:
10.68–90.41), with the highest values observed for articles published in 2012, 2013, and 2019. The three most cited articles were ‘Preoperative Chemoradiotherapy for Esophageal or Junctional Cancer’¹, ‘Risk of Ischemic Heart Disease in Women after Radiotherapy for Breast Cancer’², and ‘Overall Survival with Durvalumab after Chemoradiotherapy in Stage III NSCLC’³. International collaborations accounted for 36.7%. One third of corresponding authors were affiliated with radiation oncology departments, and 14.7% were female. The most common study types were randomized controlled trials, multicenter studies, and government-supported research. The United States was the leading country of corresponding authors and co-authors, followed by the United Kingdom and the Netherlands.
Conclusion: Radiotherapy research has shown steady growth in leading general medicine journals, reflecting its increasing recognition within multidisciplinary oncology. However, most articles were led by authors from non-radiation oncology institutions, a limited number of countries, and predominantly male authors. Broader authorship diversity and international representation are needed to strengthen radiotherapy’s visibility and integration in general medical literature. References: 1. van Hagen P et al.

Out of 32,800 published articles in the journals, 90 were indexed with the MeSH Major Topic “Radiotherapy,” corresponding to an average of 3.6 articles per year. In comparison, 65 hormonotherapy, 222 immunotherapy, and 23 minimally invasive surgical procedure articles were identified. Radiotherapy was the only modality showing positive annual growth (+5.36%). Two radiotherapy articles overlapped with Immunotherapy and two with Hormonotherapy.Radiotherapy articles were most frequently published in The Lancet, NEJM, and JAMA. The mean number of citations per article was 533.8. The average total citations per year was 42.35 (range
