RESUMEN
Mucosal injury is the most common complication of radiotherapy for head and neck neoplasms.The relevant symptoms include oral pain,dysphagia,decreased diet intake,and secondary infection,which can lead to the interruption of treatment and even affect the clinical efficacy and quality of life.Wound repair depends on nutrition supply.Inappropriate nutrition plan may affect the healing process.Therefore,proper nutritional strategy plays a pivotal role in promoting the healing of mucosal injury.Based on current researches on radiotherapy-induced mucosal injury and the effect of nutrients on wound healing,the epidemiology,pathophysiology,clinical manifestations and nutritional therapy for radiotherapy-induced mucosal injury were reviewed,aiming to provide references for clinical practice.
