头颈部肿瘤放疗者营养与支持治疗专家共识

放疗是头颈部肿瘤最常用的治疗手段。恶性肿瘤本身代谢异常及治疗过程中伴随的急性和晚期毒性等极易导致患者发生营养不良,其发生率高达44%~88%,其中重度营养不良的发生率为20%~40%。患者一旦发生营养不良,其治疗耐受性和敏感性会降低,治疗并发症会进一步增高,从而延长住院时间增加治疗费用,最终影响患者疗效。因此,营养与支持治疗是头颈肿瘤患者治疗的重要组成部分。为了使这部分患者得到合理、有效的营养与支持治疗,根据我国目前的肿瘤放疗和肿瘤营养治疗现状,参考国内外相关指南,制定适合我国情况的头颈部肿瘤放疗患者营养与支持治疗专家共识非常必要。

Expert consensus on nutrition support therapy for head and neck cancer patients receiving radiotherapy

Radiotherapy is the most commonly used treatment for head and neck cancer (HNC).Due to the metabolic abnormalities of malignant tumors and acute and advanced-stage toxic events,the incidence of malnutrition in HNC patients is high up to 44%-88%,and 20%-40% for severe malnutrition. The treatment tolerance and sensitivity will be reduced and the risk of complications will be elevated once patients present with malnutrition,which prolong the length of hospital stay,increase the medical expanse and eventually affect the clinical efficacy. Consequently,nutrition support therapy is a pivotal part of clinical treatment for HNC patients. In order to deliver reasonable and effective nutrition support therapy for HNC patients,it is of high necessity to establish expert consensus on nutrition support therapy for HNC patients in China according to the current situation of cancer radiotherapy and nutrition treatment in China and relevant guidelines at home and abroad.
