242例老年结直肠癌术前MNA-SF与NRS2002营养筛查结果及预后分析

目的:分析242例老年结直肠癌术前简易营养评价法(MNA-SF)与营养风险筛查2002(NRS2002)营养筛查结果及其与预后的关系.方法:242例老年结直肠癌患者术前均采用MNA-SF和NRS2002评估营养状况,分析评估结果与临床预后的关系,比较两营养筛查工具价值.结果:MNA-SF营养风险组120例(49.59%),营养正常组122例(50.41%);NRS2002营养风险组99例(40.91%),营养正常组143例(59.09%),两工具筛查结果差异不显著(P>0.05),检验一致率91.32%;MNA-SF和NRS2002筛查营养风险与年龄、病程、肠梗阻、分化程度、TNM分期和淋巴结转移有关;18例患者接受营养支持,其中MNA-SF营养风险组16例(13.33%%),营养正常组1例(0.82%);NRS2002营养风险组18例(18.18%);MNA-SF和NRS2002筛查营养风险组并发症发生率均高于营养正常组,住院时间均长于营养正常组,术后复发率和死亡率高于营养正常组,差异具有统计学意义(P<0.05);MNA-SF营养风险组与NRS2002营养风险组比较,住院时间差异有统计学意义(P<0.05).结论:MNA-SF和NRS2002用于老年结直肠癌患者术前营养风险筛查,均有较高预后指导价值,均适于临床营养风险筛查.

Preoperative Nutritional Screening Results of MNA-SF and NRS2002 in 242 Elderly Patients with Colorectal Cancer and Their Relationship with Prognosis

Objective:To analyze the preoperative nutritional screening results of the Mini Nutritional Assessment Short Form( MNA-SF) and nutritional risk screening 2002 ( NRS2002) in 242 elderly patients with colorectal cancer and their relationship with prognosis.Methods:MNA-SF and NRS2002 were used to e-valuate the nutritional status of 242 elderly patients with colorectal cancer before operation. The relationship between the evaluation results and the clinical prognosis was analyzed, and the value of the two nutritional screening tools was compared. Results: There were 120 cases ( 49. 59%) in MNA-SF nutritional risk group and 122 cases (50.41%)in MNA-SFnormal nutrition group while there were 99 cases (40.91%) in NRS2002 nutritional risk group and 143 cases (59.09%) in NRS2002 normal nutrition group,without significant differ-ence ( P>0. 05 ) . The consistent rate of test was 91. 32%. The nutritional risk screened by MNA-SF and NRS2002 was related to age,course of disease,intestinal obstruction,differentiation degree,TNM stage and lymph node metastasis. 18 patients received nutritional support,including 16 cases (13.33%%) in MNA-SF nutritional risk groupand 1 case ( 0. 82%) in MNA-SFnormal nutrition group, 18 cases ( 18. 18%) in NRS2002 nutritional risk group. The incidence rates of complications in MNA-SF and NRS2002nutritional risk groupwere higher than those in normal nutrition groups,the hospitalization time was longer than that of normal nutrition groups, postoperative recurrence rate and mortality rate were higher than those of normal nutrition groups,with statistically significant differences ( P<0.05) . There was a statistically significant difference in the length of hospital stay between the MNA-SF nutritional risk group and the NRS2002 nutritional risk group( P>0.05).Conclusion:MNA-SF and NRS2002 are of high guidance value in preoperative nutritional risk screen-ing for elderly patients with colorectal cancer,and both of them are suitable for clinical nutritional risk screen-ing.
