Abstract：With the development of image-guided technology, the accuracy of prostate cancer target location has been significantly improved. Accurate target location is a prerequisite for increasing the output dose of prostate cancer and reducing the toxicity of dangerous organs. The toxicity of most of dangerous organs in image-guided radiotherapy (IGRT) for prostate cancer has been effectively controlled, but there is still a certain probability of radiation proctitis. Hydrogel is a kind of adjuvant radiotherapy instrument that can effectively reduce the rectal toxicity of prostate cancer IGRT. Currently, hydrogel is widely used in foreign countries, but it is rarely used in China. The main contents of domestic and foreign application reviews are focused on the protective effect of hydrogels on rectum. This review introduces the latest progress in the application of hydrogels in prostate cancer IGRT, including the surgical procedure of combined gold benchmark markers and the safety evaluation of hydrogel injection. At the same time, the effect of hydrogel on reducing rectal toxicity is further summarized. It is hoped that this review will provide some theoretical reference for the further application of hydrogels in China.
