肠外营养支持对胃癌新辅助化疗病人围术期营养状态和免疫功能的影响

目的:探讨肠外营养(PN)支持对胃癌新辅助化疗病人营养状态和免疫功能的影响。方法:选择局部进展期胃癌病人60例,随机分为PN组和对照组,每组各30例,两组病人均可经口进食。对照组病人经口进食;PN组经口进食+术前化疗期间行PN支持,比较两组病人化疗前后、手术前后的营养状况、免疫功能和术后恢复情况。结果:(1)两组病人化疗2周期后血清清蛋白(ALB)、转铁蛋白(TF)、前清蛋白(PA)呈下降趋势,与化疗前比差异有显著性统计学差异(P0.05),而PN组各指标高于对照组(P0.05)。(2)两组病人化疗2周期后IgA、IgG、IgM、CD4+、CD4+/CD8+呈下降趋势,与化疗前比差异有显著性统计学差异(P0.05),而PN组各指标高于对照组(P0.05)。(3)PN组病人化疗的不良反应少于对照组(P0.05)。(4)术后第7天,PN组病人ALB、TF、PA和IgA、IgG、IgM、CD4+、CD4+/CD8+水平均高于对照组,差异有显著性统计学意义(P0.05)。结论:胃癌新辅助化疗病人在化疗期间给予PN支持有助于提高其化疗期间和术后的营养状态,减少免疫功能损伤和化疗的不良反应。

The influence of parenteral nutrition support to perioperative nutritional status and immune function in patients with neoadjuvant chemotherapy for gastric cancer

Objective:To observe the influence of parenteral nutrition support on nutritional status and immune function in patients with neoadjuvant chemotherapy for gastric cancer.Methods:60 patients with locally advanced gastric cancer were randomly divided into PN group and control group,30 cases in each group.The nutritional status and immune function were compared.Results:Adverse reaction of chemotherapy in PN group was less than in control group (P ＜ 0.05).ALB,TF.PA and IgA,IgG,IgM,CD4+ and CD4+/CD8+ were all higher in PN group than in control group 7 days after surgery (P ＜ 0.05).Conclusion:Parenteral nutrition support is helpful to improve patients' nutritional state during chemotherapy and operation.
