我国关于肿瘤患者营养风险及营养不良的研究逐年增多，肿瘤患者营养风险及营养不良的研究在国内外已经引 起越来越多的重视。研究显示，我国肿瘤患者营养风险和营养不良的发生率极高，患病率可高达 40%~80%，晚期恶性肿瘤 患者的营养不良和营养风险发生率则更高。营养风险和营养不良的发生严重影响肿瘤患者的预后，降低患者对手术、放疗 和化疗的耐受性和敏感性，降低患者的生活质量，减少生存时间。合理的营养治疗可以缩短住院时间，降低并发症发生 率和住院费用，改善患者生活质量，降低总死亡率，同时增加患者总生存期。由此看出，肿瘤患者的临床营养治疗日 趋重要，对恶性肿瘤患者采取积极有效的早期干预治疗具有重要意义。因此，本文总结了近年来国内肿瘤患者临床营 养研究的进展，就国内关于肿瘤患者的临床营养研究现状进行综述，提出了肿瘤营养治疗和营养研究的新思路，即在恶性 肿瘤发生、发展中尽早使用合适的营养筛查工具如营养风险筛查量表、主观全面评定量表对患者进行营养筛查及营养评估， 在有营养风险和营养不良的患者中给予合理、有效的营养治疗，这对于改善患者生活质量及疾病转归具有积极的临床价值。

The study of nutritional risk and malnutrition of tumor patients increased year by year, which has drawn more and more attention both at home and abroad. Clinical trials showed that cancer patients usually suffered from nutritional risk and malnutrition in China, and the incidence could be 40%~80%, incidence of malnutrition and nutritional risk is higher in patients with advanced malignant tumor. Nutritional risk and malnutrition produces seriously influenced tumor patients’ prognosis, reduced the tolerance and sensitivity of surgery, radiotherapy and chemotherapy, lowered the quality of life and overall survival time. Effective nutritional therapy shortened the length of hospital stay, lowered incidence of complications and hospitalization costs upgraded the quality of life, decreased morality and increased survival time. Tumors in patients with clinical nutrition therapy had become increasingly important, active and effective intervention in patients with malignant tumors is of great significance. This article concluded the research about the progression of nutrition research, reviewed the status of clinical nutrition research of tumor patients and indicated a new idea about tumor treatment and nutritional research. In occurence and development of tumor, using appropriate nutritional screening tools such as nutritional risk screening and subjective global assessment for patients with comprehensive nutritional screening and evaluation as soon as possible, reasonable and effective nutritional therapy has positive clinical value to patients, which will upgrade the quality of life and improve the prognosis.
