Abstract Objective To analyze the main research contents, research frontier, author and institutional cooperation of radiotherapy for endometrial carcinoma in China and to provide ideas for follow-up studies. Methods China National Knowledge Network (CNKI) was used as the data source, and the retrieval time was From January 1990 to December 2020. A total of 520 literatures related to radiotherapy for endometrial cancer were retrieved and analyzed using Cite- Space visualization software, including keyword clustering and emergence analysis, as well as co-occurrence analysis between authors and research institutions. Results In 2000, the number of published articles gradually increased, and from 2001 to 2010, the number of published articles was basically stable at more than 20. A total of seven clusters were obtained by cluster analysis, mainly including radiotherapy, endometrial cancer, chemotherapy, comprehensive therapy, gynecological tumor, malignant tumor, postoperative radiotherapy, etc. Six emergent words were obtained by emergent analysis, which were malignant tumor, survival rate, pelvic lymph node metastasis, treatment, chemotherapy and radiotherapy. The authors’ collaboration network was mainly composed of three collaboration groups, namely Sheng Xiugui, Kong Weimin and Wang Jianliu. The map density of institutional cooperation network was 0.0034. Conclusion The foremost current research hotspots of radiotherapy for endometrial carcinoma are intensity-modulated radiotherapy, helical tomotherapy, three-dimensional brachytherapy, and biological intensity modulated radiotherapy. Although research institutions are widely distributed, the institutional cooperation is scattered.
