Resting energy expenditure in patients with malignant tumors / 中华临床营养杂志

ABSTRACT

Energy metabolism varies in different periods during the lifetime or in different pathological states. Resting energy expenditure (REE) may increase in some patients with malignant tumors, but may also show no significant difference when compared with healthy people or patients with benign tumors. The alteration of REE may be related to tumor site, pathologic stage, methods of treatment, and/or laboratory tests. The efficacy of a certain therapy may also affect REE in patients with malignant tumors when a therapy is effective, the value of REE can return normal; however, when the treatment fails, REE will not be improved or become even higher.Mechanism governing the abnormalities of REE in patients with malignant tumors may be associated with the abnormal nutrition metabolism and the regulations of relevant cytokines.
