Abstract: Pancreatic cancer, as a common malignant tumor of the digestive system, has a very low survival rate. In recent years, pancreatic cancer has made great progress in diagnostic methods, radiation therapy techniques, and systemic chemotherapy, but its therapeutic effect has not been considerably improved. As a new type of tumor research platform, organoids have made research progress in many fields. Constructing pancreatic cancer organoids is of great research value to guide the individualized treatment of pancreatic cancer. This article reviews the research and clinical application prospect of organoid model in radiotherapy of pancreatic cancer.
