【摘要】 癌性营养不良在恶性肿瘤患者中的发生率高达31%~87%,导致患者对放疗的耐受性差、依从性下降,治疗中断或延后,明显影响预后。放疗时间延长及同步放化疗会加重患者的营养不良。总体主观评定法(Patient-generated subjective global assessment,PG-SGA)最适合恶性肿瘤患者治疗前营养风险筛查,根据评估结果,在放疗早期和放疗后选择合适的营养支持进行营养干预,可以改善患者的营养状况并提高疗效。更多还原

【Abstract】 Cancer malnutrition observed in 31%~87%patients with cancer can reduce the tolerance and compliance to radiotherapy,interrupt or delay the treatment,and significantly affect the prognosis.The malnutrition may be aggravated when the duration of radiotherapy is prolonged and chemotherapy is applied concurrently.PG-SGA is the most suitable method for nutritional risk screening in patients with malignant tumor.According to the result of nutrition assessment,giving the adaptive nutrition support can improve the nutritional status of patients and the curative effect in the early stage of radiotherapy,as wells as post radiotherapy.更多还原
