NRS 2002、PG-SGA、BMI、TF在胃癌营养筛查与评估中的作用

NRS 2002,PG-SGA,BMI,TF in nutritional screening and assessment of gastric cancer patients

目的对住院胃癌患者,应用NRS 2002及PG-SGA及BMI、TF测定,了解NRS 2002、PG-SGA在胃癌营养筛查评估中的作用,分析BMI、TF等与NRS 2002、PG-SGA的相关性。方法采用连续入组法,以本院2015年1月至2016年9月住院的胃癌患者136例为研究对象,入院24小时内应用NRS 2002进行营养风险筛查、PG-SGA进行营养状况评估,同时测定其BMI、TF。结果应用NRS 2002进行营养风险筛查,无营养风险(NRS 2002<3分)的患者共64例(47%),有营养风险(NRS 2002≥3分)的患者共72例(53%);应用PG-SGA进行营养评估,营养良好(PG-SGA 0~1分)的患者共5例(4%),可疑营养不良(PG-SGA 2~3分)的患者共21例(15%),中度营养不良(PG-SGA 4~8分)的患者共49例(36%),重度营养不良(PG-SGA≥9分)的患者共61例(45%)。年龄均与NRS 2002、PG-SGA呈正相关,具有统计学意义(P<0.01),而TF、BMI、体重均与NRS 2002、PG-SGA呈负相关,具有统计学意义(P<0.05);而身高与NRS 2002、PG-SGA呈正相关,但无统计学意义(P>0.05);NRS 2002与PG-SGA呈正相关,有统计学意义(r=0.565,P<0.01)。结论胃癌患者术前营养不良发生率高,营养风险亦较高,NRS 2002及PG-SGA、BMI、TF等均有助于胃癌患者的营养筛查与评估,联合应用可能更有利于胃癌患者的围术期营养治疗。

Objective To understand the application of nutrition risk screening 2002 （NRS 2002）, patient-generated subjective global assessment （PG-SGA）, body mass index （BMI）, serum transferrin （TF） in nutritional screening and assessment of the hospitalized patients with gastric cancer and analyze the correlation between them. Methods 136 patients with gastric cancer hospitalized in our hospital from January 2015 to September 2016 were consecutively enrolled in this study. Nutritional risk screening by NRS 2002 and assessment of nutritional status by PG-SGA were performed in their frst 24 hours in hospital. Their BMI, TF were measured at the same time. Results There were 64 patients （47%） of non nutritional risk （NRS 2002〈3）, while 72 patients （53%） of nutritional risk （NRS 2002≥3）. There were 5 patients （4%） of eutrophy （PG-SGA 0~1）, 21 patients （15%） of suspected malnutrition （PG-SGA 2~3） and 49 patients （36%） of moderate malnutrition （PG-SGA 4~8） while there were 61 patients （45%） of severe malnutrition （PG-SGA≥9）. The age was positively correlated with NRS 2002 and PG-SGA （P〈0.01）. The TF, BMI, body weight were negatively correlated with NRS 2002 and PG-SGA （P〈0.05）, and the body height was not correlated with NRS 2002 and PG-SGA （P〉0.05）. There was a signifcant correlation between NRS 2002 and PG-SGA score （r= 0.565, P〈0.01）. Conclusions There is high incidence of preoperative malnutrition and nutritional risk in patients with gastric cancer. NRS 2002, PG-SGA and BMI, TF can be benefcial for the overall assessment of nutritional status and the analysis of nutritional risk for patients with gastric cancer. The combination of them may be more helpful in perioperative nutritional treatment in patients with gastric cancer.
