Protein-calorie malnutrition, vitamin and other deficiencies, and weight loss frequently develop in cancer patients. Although there is no evidence that aggressive nutritional management prolongs survival, it may improve the quality of life. Efforts should be made to maintain adequate daily caloric intake with appropriate food selection and with control of complications interfering with nutrition. In selected patients, intravenous hyperalimentation can provide adequate nutrition during potentially effective chemotherapy or radiotherapy. Elemental diets also may be a source of complete or supplemental nutrition. Further experience with both approaches will help to clarify their role in the nutritional management of the patient with advanced cancer.
蛋白质 - 热量营养不良、维生素及其他营养缺乏以及体重减轻在癌症患者中经常出现。尽管没有证据表明积极的营养管理能延长生存期，但它可能改善生活质量。应通过适当的食物选择以及控制干扰营养的并发症来努力维持足够的每日热量摄入。在特定患者中，静脉高营养可在可能有效的化疗或放疗期间提供足够的营养。要素饮食也可能是完全或补充营养的来源。对这两种方法的进一步经验将有助于阐明它们在晚期癌症患者营养管理中的作用。
