不同筛查工具对老年肿瘤患者营养筛查的比较

目的：探讨在老年肿瘤患者中合理选择营养风险筛查工具,以便及时实施营养干预,改善由于营养因素所导致的不良临床结局。方法：对130例老年肿瘤患者应用微型营养评价精法（MNA-SF）和患者主观全面评价法（PG-SGA）进行营养筛查,以白蛋白和前白蛋白为标准评定上述工具的灵敏度、特异度。结果：以白蛋白为参考标准,MNA-SF、PG-SGA的灵敏度分别为55.7%、68.3%,特异度分别为45.1%、89.7%。以前白蛋白为参考标准,MNA-SF、PG-SG的灵敏度分别为67.1%、75.2%,特异度分别为51.0%、93.1%。结论：PG-SGA考虑到多个影响营养的复杂问题,使评价结果更接近于肿瘤患者的实际营养状况。较之MNA-SF,PG-SGA更适用于老年肿瘤患者,值得推广。

Comparison of Different Tools for Nutritional Screening in Elderly Cancer Patients

Objective] To probe into the rational choice of nutritional risk screening for elderly cancer patients to carry out nutritional intervention and improve bad clinical results due to nutritional factors. Method] We used MNA-SF and PG-SGA to assess the nutritional status of 130 elderly cancer patients, and chose albumin and prealbumin as the indicators for assessing the sensitivities and specificities of these two tools. Result] In the detection of albumin, the sensitivities of MNA-SF and PG-SGA were 55.7% and 68. 3% respectively, and the specificities were 45.1% and 89.7% respectively. In the detection of prealbumin, the sensitivities of MNA-SF and PG-SGA were 67.1% and 75. 2% respectively, and the specificities were 51.0% and 93.1% respectively. Conclusion] Considering the complex multiple nutritional problems, PG-SGA made evaluation results more closer to the actual nutritional status of patients with tumor. Compared with MNA-SF, PG-SGA was more suitable for elderly patients with tumor, which was worth promoting.
