营养不良在肿瘤患者中发生率高，降低治疗疗效及增加治疗副反应, 因此制定全国规范化肿瘤营养治疗示范病 房标准十分必要。肿瘤营养疗法是遵循肿瘤学原理，运用营养学方法，治疗肿瘤及其并发症，从而改善身体状况及预后的 过程，包括营养诊断、营养治疗、疗效评价三个阶段。而规范化肿瘤营养治疗示范病房是规范实施肿瘤营养疗法，具有示范、 引导作用的单位 [ 含病房、科室和（或）医院]。三级综合医院、有条件的二级综合医院以及所有肿瘤专科医院均要求积极 创建“规范化肿瘤营养治疗示范病房”。在全国范围内建立规范化肿瘤营养治疗示范病房，对于防治肿瘤相关性营养不良， 推动营养治疗的合理应用，提升肿瘤治疗水平，维护患者医疗安全，提高患者生活质量，延长患者生存时间，节约医疗费 用等具有重要意义。

 Abstract: Malnutrition is frequently present among cancer patients, which diminishes treatment efficacy while increasing therapeutic side effects. Therefore, it is essential to set standards for National Good Nutrition Therapy Ward (GNT Ward) to regulate the nutritional care practice in a clinical setting. Cancer nutrition therapy (CNT), developed based on oncology and nutrition theory, aims to treat cancer and its complications, enhance physical conditions, and improve the prognosis via nutritional interventions. CNT consists of 3 stages, including nutritional diagnosis, nutritional intervention, and efficacy evaluation. A GNT Ward title is granted to a ward, a department, and/or a hospital, who performs the standardized CNT. These units showcase CNT in practice and provide guidance to their counterparts. Grade III comprehensive hospitals, capable Grade II comprehensive hospitals, and all cancer specialized hospitals are encouraged to establish a GNT Ward. The establishment of the GMT Ward is of great significance on a national scale regarding preventing and/or treating cancer-related malnutrition, improving cancer therapy efficacy, securing the health care safety for patients, ameliorating the quality of life, extending the survival time, and saving medical costs.
