恶性肿瘤患者静息能量代谢研究现状

能量代谢可以反映人体代谢基本情况,不同生理或病理时期机体代谢特征不同.恶性肿瘤负荷状态下,多数患者处于高能耗状态,但也有部分患者静息能量代谢无明显变化,这种改变可能与肿瘤的类型、病理分期、治疗手段及实验方法等因素密切相关.治疗效果对肿瘤患者静息能量消耗可产生不同影响:治疗有效时,患者静息能量消耗可恢复至正常;治疗无效时,患者静息能量代谢无改善甚至能耗量增加.恶性肿瘤患者能量代谢异常的机制可能与机体营养物质代谢异常及相关细胞因子调控有关.

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.
