Abstract:
With the development of modern radiotherapy techniques,radiotherapy has been widely used in the multimodality therapy for various malignant tumors,including head and neck cancers such as nasopharyngeal cancer and laryngeal cancer.A combination of surgery and radiochemotherapy significantly improves patients' cure rate and survival time;however,with the increase in survival time,some patients receiving radiotherapy develop marked cognitive impairment.Ionizing radiation-induced cognitive impairment mainly nanifests as hippocampus-dependent cognitive impairment,which is associated with inhibited hippocampal neurogenesis due to ionizing radiation.Therefore,it is necessary to investigate the mechanisms of the inhibition of hippocampal neurogenesis by ionizing radiation.This article reviews the molecular mechanism of neurogenesis disorders induced by ionizing radiation.
