癌患者に対する栄養療法

Cancer cachexia has been defined as a multifactorial syndrome defined by an ongoing loss of skeletal mass that cannot be fully reserved by conventional nutritional support and lead to progressive functional impairment. The diagnostic criterion for cachexia is weight loss greater than 5％, or weight loss greater than 2％ in individuals already showing BMI＜20 or sarcopenia. Multimodal management plan including nutrition, exercise, ant-inflammatory strategies, and other adjuncts is required for all cancer patients with anti-cancer therapy （operation, chemotherapy, radiotherapy） to avoid weight loss and keep quality of life. Enteral nutrition by means of oral nutritional supplements and tube feeding offers ensuring nutrient intake in cases when normal food intake is in adequate. Routine parenteral nutrition in chemotherapy does not improve prognosis.
