Abstract

Graphic abstract

Purpose: The aim of this study is to visualize and analyze the research hot pots in radiation therapy for rectal cancer and provide researchers with a clear and visual reference for subsequent studies.

Methods: The literature scientometric analysis about “external beam radiation therapy (EBRT) for rectal cancer” was made through the WoSCC (2010 to 2019). And the data was visualized and analyzed by the Microsoft Office Excel (2019) and CiteSpace (V. 5.7.R1).

Results: 4,263 relevant articles were downloaded. The number of published articles per year has been increasing (2010-2020). The United States published the highest number of articles. The UK has the strongest partnerships with other countries/regions. Leiden University has the highest number of published articles and University Texas MD Anderson Cancer Center has extensive collaborations with other academic institutions. The number of articles published in the Diseases of the Colon Rectum is the most, and the Journal of Clinical Oncology is the most cited. 27 articles became the strongest burst citations lasting until 2020. In recent years, a lot of research has been done on “watch and wait”, “short-course radiotherapy”, “MRI”, “neoadjuvant radiotherapy, “MRI in rectal cancer”, “chemotherapy regimen improvement”, “adding adjuvant chemotherapy”, and so on.

Conclusion: The current research hot pots may be the “watch and wait”, “short-course radiotherapy”, “MRI”, “neoadjuvant chemoradiotherapy”, “MRI in rectal cancer”, “chemotherapy regimen improvement”, and “adding adjuvant chemotherapy”.
