Abstract To sort out the relevant studies on the fertility preservation of cancer patients in the past decade in order to present the research hotspots and research frontiers, and to compare the hotspots related to fertility preservation of cancer patients at home and abroad, so as to provide evidences for the further researches related to fertility preservation in China. Methods: The literatures had been collected from the core databases, such as China National Knowledge Infrastructure, Wanfang, Wipu, Sinomed, Pubmed, and Web of science from January 2012 to December 2021, and were analyzed by Citespace software. Results: A total of 4574 English literatures and 485 Chinese literatures were included for analysis. The English and Chinese literatures on fertility preservation of the cancer patients had been rising year by year in the last decade, but the rising trend of foreign literatures were significantly higher than that of Chinese literatures. The related literatures from United States were the leader in fertility preservation of cancer patients, which were far ahead from other countries. The studied cancer patients mainly included breast cancer, cervical cancer, and endometrial cancer, and so on. The age of the population in these studies had gradually shifted from those of childbearing age to those of children and adolescents with cancer. The main techniques in these studies included the modification of surgical model and the vitrification used for embryo freezing, the oocyte freezing, the sperm cryopreservation, and the ovarian tissue freezing, and so on. The foreign guidelines of the fertility preservation of the cancer patients were well established relatively, while the guidelines of the fertility preservation of the cancer patients were rather lacking in China. Conclusion: Fertility preservation is in its infancy in China, and the research depth and breadth of which still needs to be expanded. The international research hotspots of the fertility preservation should be learned by China and the Chinese guideline of the fertility preservation should be improved, so as to ensure the standardization and safety of the fertility preservation process in China.
