目的  调查宜昌市第二人民医院肿瘤科新入院恶性肿瘤患者的营养状况，分析这些营养状况的可能原因，探讨营 养治疗对恶性肿瘤患者预后的可能影响。方法  收集2015年7月~2015年9月新入住宜昌市第二人民医院的恶性肿瘤患者， 登记其年龄、性别、诊断、身高、体重等基本资料，应用营养风险筛查表NRS 2002 进行营养风险筛查。用统计学方法分 析各指标之间的差异及联系。结果  两个月时间收集到51例恶性肿瘤患者，分期均为中晚期，其中男性23例，女性28 例； 年龄区间为 27~77 岁。入院时的营养风险发生率为 90.2%，营养不良发生率为 9.8%。进一步分析显示：男性营养风险发 生率（95.7%）高于女性营养风险发生率（85.71%）；中老年患者（＞50岁组）营养风险发生率高于青年（≤50岁组）， 差异均有统计学意义（P 值分别为0.042 和 0.036）。结论  我院住院的恶性肿瘤患者中，大部分为中晚期患者，其营养风 险发生率高，并且不同年龄、性别营养风险发生率差异大，应重视患者的营养状况及营养风险差异，针对营养风险原因进 行处理，营养状况直接影响患者预后，在临床抗肿瘤治疗的同时积极进行营养治疗将对患者有积极意义。

 Objective  We investigated the nutritional status of newly admitted cancer patients in oncology department of the Second Hospital of Yichang/Second People’s Hospital, analysis the possible causes of these nutritional status, to explore the possible effect of nutritional therapy on the prognosis of patients with malignant tumor. Methods  We collected and registered basic data of patients with malignant tumor who hospitalized in the Second Hospital of Yichang/Second People’s Hospital during July 2015 to September 2015. Basic data on age, sex, diagnosis, height and weight were collected. NRS 2002 table was used to identify nutritional risk screening. Statistical analysis was used to analyze possible causes of nutritional status. Results  51 cases of malignant tumor were collected in two months. The stages were all in the middle and late stages, including 23 males and 28 females. The age range was 27~77 years old. At admission, the incidence of nutritional risk was 90.2%, and the incidence of undernutrition was 9.8%. Further analysis showed that the men's incidence of nutritional risk (95.7%) was higher than the  women’s (85.71%); Middle aged and elderly patients’ (>50years) incidence of nutritional risk was higher than the young (≤50 years), the differences were statistically significant (the P values were 0.042 and 0.036 respectively). Conclusions  Most of the patients with malignant tumor in our hospital were middle and advanced patients. The incidence of nutritional risk was high, and the incidence of nutritional risk varies greatly in different age and sex. We should pay attention to the nutritional status and nutritional risk and the causes of nutritional risk. For the nutritional status directly affected the prognosis of the patients, active nutritional therapy in clinical antitumor treatment will be beneficial for patients.
