Radiotherapy is one of the main treatment modalities for cancer. However, some cancer patients will gradually develop resistance to radiotherapy, leading to tumor recurrence and metastasis. Radiation therapy usually promotes the secretion of exosomes from tumor cells and causes changes in their internal components. Accumulating evidence reveals that exosomes-mediated radiation-induced bystander effect (RIBE) is closely involved in radiotherapy resistance. In this article, we will discuss the relationship between exosomes and RIBE, highlight the effect of exosome components on resistance to radiation, and emphasize the role of exosome inclusion as a tumor biomarker for the prognosis of tumor treatment to develop new therapeutic approaches.
