摘要
目的探讨营养风险筛查(NRS2002)对胃癌手术患者营养评估特点。方法应用NRS2002和整体营养状况主观评估(PG-SGA)对80例胃癌手术患者进行评测。结果 PG-SGA评测营养不良发生率高于NRS2002,差异有统计学意义(P<0.05);PG-SGA与NRS2002评测结果具有较好的一致性(k=0.74,P<0.01),相对于PG-SGA评测,NRS2002的敏感性为83.02%、特异性为96.30%,阳性预测值为97.78%,阴性预测值为74.29%。PG-SGA与总蛋白、白蛋白、血红蛋白、饮食减少、体重下降均存在明显相关关系(P<0.01),NRS2002仅与饮食减少、体重下降存在明显相关关系(P<0.01),PG-SGA与NRS2002评分也存在明显的相关关系(P<0.01)。结论 NRS2002对胃癌手术患者是一种简单有效的营养风险筛查方法,但存在一定偏差,有可能遗漏具有营养风险的患者。
Objective To discuss the characteristics of Nutritional Screening Risk 2002 （NRS2002） in assessing the nutritional status of gastric cancer patients who underwent surgery. Methods 80 patients with gastric cancer were evaluated with PG-SGA and NRS2002 after surgery to explore the characteristics of nutrition status. Results The rate of malnutrition by PG-SGA was significantly higher than that by NRS2002; the difference was significant （P 〈 0.05 ）. The results of the two nutrition screening tools had good agreement （ k = 0. 74, P 〈 0.01 ）. The sensitivity of NRS2002 was 83.02% , the specificity was 96.30%, positive predictive value was 97.78% and the negative predictive value was 74.29% according to the results of PGSGA. The result of PG-SGA had a significant relationship with the scores of total protein, albumin, hemoglobin, as well as the rate of weight loss （P 〈 0. 01 ）, while the result of NRS2002 only correlated with the rate of weight loss and the extent of reduced food intake （P 〈 0. 01 ）. The score of PG-SGA and NRS2002 were highly correlated （P 〈 0. 01 ）. Conclusion NRS2（XY2 is an easy and effective method to evaluate the nutritional status of gastric cancer patients after surgery. However, it is possible to miss the patients with nutritional symptoms because of the deviation.
