分析营养风险指数（NRI）与营养控制状态（CONUT）评分及尿素肌酐比值（UCR）对胃癌患者营养状况和预后质量的评价作用。

选取徐州市第一人民医院2021年1月至2023年1月收治的197例胃癌患者进行回顾性分析，使用营养风险筛查2002量表（NRS 2002）评估其营养状态，并将NRS 2002评分≥3分、<3分者分别纳入营养风险组、无营养风险组，对比2组患者NRI、CONUT、UCR差异，使用Pearson相关性分析计算NRI、CONUT、UCR与白蛋白（ALB）、前白蛋白（PA）、血红蛋白（Hb）等的相关性；按照患者随访1年预后，将患者分别纳入预后良好组、预后不良组，对比2组基线资料和营养状况、UCR，使用Logistic多因素回归模型归纳影响患者预后的相关因素。

197例患者中，71例NRS 2002评分≥3分，营养风险组NRI评分和ALB、PA、Hb均较无营养风险组更低，其CONUT评分、UCR较无营养风险组更高（P<0.05）。Pearson相关性分析示，NRS 2002评分、CONUT评分、UCR均与ALB、PA、Hb呈负相关，NRI评分与ALB、PA、Hb呈正相关（P<0.05）。197例患者均获得有效随访，随访时间12~42个月，中位随访时间31个月。随访期间37例患者预后不良。Logistic多因素回归分析示，体重指数<18.5 kg/m²、TNM分期Ⅲ期、NRS 2002评分≥3分、CONUT评分≥3分、UCR≥20均为胃癌患者预后不良的独立风险因素，NRI评分≥99分为保护性因素（P<0.05）。

NRI、CONUT、UCR均能够指导胃癌患者营养状况的评估，且上述参数结合体重指数、TNM分期有望为胃癌患者预后质量的预测提供新的思路。

To analyze the evaluation of nutritional risk index (NRI), nutritional control status score (CONUT) and urea-creatinine ratio (UCR) on nutritional status and prognosis quality of gastric cancer patients.

A total of 197 patients with gastric cancer admitted to Xuzhou First People’s Hospital from January 2021 to January 2023 were selected and retrospectively analyzed, and their nutritional status were evaluated by the Nutrition Risk Screening Scale 2002 (NRS 2002). Those with NRS 2002 scores of ≥3 and <3 were respectively included in the nutrition risk group and the non-nutrition risk group. The differences of NRI, CONUT and UCR between the two groups were compared, and the correlations between NRI, CONUT, UCR and blood albumin (ALB), prealbumin (PA), hemoglobin (Hb), etc. were calculated using Pearson correlation analysis. According to the patients' prognosis after one-year follow-up, the patients were divided into the good prognosis group and the poor prognosis group, and the baseline data, nutritional status and UCR of the two groups were compared. Logistic multivariate regression model was used to summarize the related factors affecting the prognosis of the patients.

Among the 197 patients, 71 patients had NRS 2002 score ≥3. The NRI score, ALB, PA and Hb in the nutritional risk group were lower than those in the non-nutritional risk group, and their CONUT score and UCR were higher than those in the non-nutritional risk group (P<0.05). Pearson correlation analysis showed that NRS 2002 score, CONUT score and UCR were negatively correlated with ALB, PA and Hb, while NRI score was positively correlated with ALB, PA and Hb (P<0.05). All 197 patients were effectively followed up for 12 to 42 months, with a median follow-up time of 31 months. During the follow-up period, 37 patients had poor prognosis. Logistic regression analysis showed that body mass index<18.5 kg/m², TNM stage Ⅲ, NRS 2002 score ≥3, CONUT score ≥3 and UCR≥20 were all independent risk factors for poor prognosis of patients with gastric cancer, and NRI score ≥99 was a protective factor (P<0.05).

NRI, CONUT and UCR can guide the evaluation of nutritional status of patients with gastric cancer, and the above parameters combined with body mass index and TNM staging are expected to provide new ideas for predicting the prognosis quality of patients with gastric cancer.
