合理的营养治疗有利于改善肿瘤患者的生活质量、减少并发症,且降低治疗成本、改善预后。 中国肿瘤患者营养不 良发生率高达 80. 4%,营养治疗率却只有 33. 7%。 因此,针对肿瘤患者营养不良需要加强关注,提高肿瘤患者营养治疗的诊 治水平。 基于此,汇总 2021 年肿瘤营养学科最新研究进展及未来发展方向,包括恶性肿瘤患者营养状态流行病学、营养不良 评估诊断的改良、膳食结构的推荐、肿瘤营养治疗及预测指标、特殊人群的营养关注等多个方面取得的高水平的研究成果,为 肿瘤营养治疗提供循证医学证据。

Reasonable nutrition therapy is closely related to the treatment and prognosis of tumor patients which is not only helpful to improve the quality of life of tumor patients and reduce the complications but also can reduce the treatment cost. The survey results of the Professional Committee of Tumor Nutrition Therapy of China Anti-Cancer Association show that the overall malnutrition incidence rate of inpatient tumor patients in tertiary hospitals in China is 80. 4% while the nutrition treatment rate of malnourished patients is only 33. 7%. The current lack of attention to nutrition diagnosis and treatment of tumor patients and the lack of high-level clinical evidence-based evidence seriously restrict the standardized diagnosis and treatment of tumor patients and the improvement of the overall diagnosis and treatment of tumor. 2021 based on the continuous efforts of scholars at home and abroad the epidemiology of nutritional status of malignant tumor patients the improvement of malnutrition assessment and diagnosis the recommendation of dietary structure tumor nutrition treatment and predictive index and the special population These researches have provided high - level and precise evidence-based medical evidence for the clinical problems that exist and need to be solved and have made the development direction of the field of oncology nutrition clearer.
