【摘 要】目的：探讨肠内营养支持方式对肿瘤科营养不良患者的治疗作用。方法：将90例肿瘤科营养不良患者随机分为40例肠外营养支持(对照组，PN组)和50例肠内营养支持(实验组，EN组)两组，分别检测两组营养支持后营养状况指标和细胞免疫指标。结果：EN组治疗30 d后血清总蛋白、白蛋白、血红蛋白均较治疗前明显升高(P均<0.05)，且改善程度好于PN组。EN组治疗30 d后血清IgG、IgA、IgM、CD3、CD4与PN组比有显著提高(P<0.05)。结论：肠内营养支持方式可以改善营养不良肿瘤患者的营养状况，增强免疫力，维持肠黏膜屏障，对肿瘤患者综合治疗有积极的作用.

    【Objective】 To investigate the efficacy of enteral nutrition in the treatment of malnutrition in cancer patients. Methods: 90 cancer patients were divided into parenteral nutrition group and enteral nutrition group randomly. Nutrition and immunocyte status were compared between two groups. Results: Serum total protein,albumin and hemoglobin increased after 30 days treatment in nutrition group.(P<0.05) Serum IgG、IgA、IgM、CD3、CD4 increased in enteral nutrition group than those in control group. (P<0.05) Conclusion: Enteral nutrition is effective in the managemment of malnutrition and strengthening the immune system. ......
