完善、充分的营养供给在头颈部癌患者的治疗和预后中占有重要地位,人们对这一问题的认识也已有时日。但是,对头颈部癌患者的营养学处理往往是理论多于实践,即文献讨论较多而临床未予重视。本文就头颈部癌患者在治疗前后的营养学概念作一简述。头颈部癌是一种消耗性很大的疾病,它可以造成机体营养不良并导致恶病质,而恶病质又将加速癌肿的扩散,如此形成的恶性循环将促使病人死亡。有的学者认为:头颈部癌病人并发症的发生和治疗上失败的一个共同原因就是营养不良。因此,耳鼻咽喉科医师对头颈部癌患者施加必要的营养学辅助治疗乃系理所当然。营养学的一般概念一、食物的能量价值。对营养学处理的讨论不外乎能量的消耗、储藏和利用。糖、脂肪、蛋白质是人体必需的营养素,它们来源于食物。葡萄糖是能量的基本来源,来自肝糖元和肌糖元,在紧急和乏氧的情况下具有重要作用。但是由于它的储藏时间只有一天,所以在临床长期饥饿状 Well-developed and adequate nutritional supplies play an important role in the treatment and prognosis of head and neck cancer patients. People have known this problem for some time. However, the nutritional treatment of patients with head and neck cancer is often more theoretical than practice, that is, the literature is more discussed and clinically neglected. This article briefly describes the concept of nutrition before and after treatment for head and neck cancer patients. Head and neck cancer is a very consumptive disease. It can cause malnutrition in the body and cause cachexia, and cachexia will accelerate the spread of cancer. The vicious circle thus formed will prompt the death of the patient. Some scholars believe that a common cause of complications and treatment failures in head and neck cancer patients is malnutrition. Therefore, it is a matter of course that otorhinolaryngologists apply necessary nutritional aids to head and neck cancer patients. The general concept of nutrition First, the energy value of food. The discussion of nutritional treatment is nothing more than the consumption, storage and use of energy. Sugar, fat, and protein are essential nutrients for the body. They come from food. Glucose is the basic source of energy, from liver glycogen and muscle glycogen, and plays an important role in emergency and hypoxia. However, due to its storage time of only one day, it is clinically chronically hungry.
