Energy Metabolism and Requirements in the Cancer Patient

摘要: Summary As a basis for assessing energy metabolism and requirements in cancer patients, selected aspects of whole-body are considered, with particular reference to basal factors that affect it. The importance protein relation wholebody is emphasized. need consider the intimate relationships between nutrition comprehensive evaluation needs patients also stressed. Published data on metabolic rate malignant disease difficult evaluate their nutritional significance. Quantitative estimates utilization major fuel sources still quite limited, but available suggest there may be change pattern utilization, lipid predominating, an altered regulation glucose metabolism, reduced efficiency some, not all, patients. best balance exogenous level total intake sufficient meet demands organs whole body cannot easily predicted and, therefore, only crude guidelines can suggested.
