研究发现,40%~80%的肿瘤患者存在营养不良,20%的肿瘤患者直接死于营养不良,营养不良肿瘤患者的5年生存率显著低于没有营养不良的患者。体重丢失是营养不良的一种表现。BosaeusⅠ等报告一组肿瘤患者(n=295)体重平均下降10%±9.4%,43%患者体重下降>10%,体重丢失的肿瘤患者其生存时间显著缩短,原因之一是体重丢失的肿瘤患者不能耐受化疗。实施营养治疗前应该常规进行营养评估,美国营养学会推荐的肿瘤患者营养评估的唯一方法为PG—SGA。由于肿瘤患者处于高代谢状态,所以肿瘤患者
The study found that 40% to 80% of cancer patients with malnutrition, 20% of cancer patients died of malnutrition directly, malnutrition patients with 5-year survival was significantly lower than those without malnutrition. Weight loss is a manifestation of malnutrition. Bosaeus I et al reported that in a group of cancer patients (n = 295) an average body weight loss of 10% ± 9.4%, 43% of patients with body weight loss> 10%, weight loss in patients with tumor life significantly shorter, one of the reasons is weight loss in patients with cancer Can not tolerate chemotherapy. Nutritional assessment should be performed routinely prior to nutritional therapy. The only recommended method of nutritional assessment for cancer patients recommended by the American Academy of Nutrition is PG-SGA. As cancer patients in a high metabolic state, so cancer patients
