【摘要】 放射性口腔黏膜炎（radiation-induced oral mucositis,RIOM）是头颈部肿瘤放疗、放化疗中常见且可限制治疗连续性的毒性反应，表现为口腔黏膜红斑、糜烂或溃疡、显著疼痛，常并发营养不良和感染。文章基于现有RIOM相关国内外指南和我国团体标准，提出一体化全周期管理模式：放疗前进行系统口腔评估、风险分层和健康教育；围疗程阶段以规范化口腔卫生管理为核心，辅以适宜的局部或全身预防措施；治疗阶段根据分级严重程度，综合应用镇痛、抗感染、营养支持和促愈合干预，必要时优化放疗计划；放疗后结合定期随访、患者报告结局（patient-reported outcome measures,PROMs）和质量改进（quality improvement,QI）指标，形成动态闭环。该模式旨在降低重度RIOM的发生率和治疗中断率，缩短愈合时间，并改善患者生活质量。更多还原

【Abstract】 Radiation-induced oral mucositis(RIOM)is a common toxic reaction that may limit continuous treatment in head-and-neck radiotherapy and chemoradiotherapy. It typically presents with oral mucosal erythema,erosions or ulcers,and severe pain,often accompanied by malnutrition and infection. Based on current national and international guidelines and the Chinese group standards,this paper puts forward an integrated,full-cycle management model,including:systematic oral evaluation,risk stratification,and health education before radiotherapy;standardized oral hygiene management supported by appropriate local or systemic prophylactic measures through the course of treatment;severity-based therapeutic strategies that combine analgesia,anti-infection,nutritional support,and pro-healing interventions during treatment,with radiotherapy plan optimized if necessary;regular follow-up combined with patient-reported outcome measures(PROMs)and quality improvement(QI)indicators to form a closed management loop. This model is designed to reduce the incidence of severe RIOM and treatment interruptions,accelerate healing,and improve patients’quality of life.更多还原
