恶性肿瘤患者的营养状态明显影响肿瘤的生长,且与预后密切相关。蛋白质代谢紊乱是恶性肿瘤患者的显著表现。作为蛋白质合成原料和分解产物的氨基酸代谢,在癌症病人中亦发生显著改变。鉴于氨基酸在恶性肿瘤代谢中的重要作用,以改变氨基酸代谢为特点的治疗方法可有助于改善恶性肿瘤的预后。根据氨基酸组成成分和作用机理的不同,以氨基酸治 The nutritional status of patients with malignant tumors significantly affects the growth of the tumor and is closely related to the prognosis. Protein metabolism disorders are a significant manifestation of patients with malignant tumors. Metabolism of amino acids as a raw material for protein synthesis and decomposition products has also undergone significant changes in cancer patients. In view of the important role of amino acids in the metabolism of malignant tumors, treatments characterized by changes in amino acid metabolism may help to improve the prognosis of malignant tumors. According to the amino acid composition and mechanism of action, amino acids are treated
