由于特殊的代谢特点及治疗相关的不良反应等原因，肿瘤患者常出现饮食量降低，导致营养不良发生率增高， 并与较差的临床结局相关。前期研究发现，有一些患者的饮食量降低容易被患者自己及临床医护人员所忽视，需要进行膳 食调查才能明确。而膳食调查需要专业的营养师完成，从而影响了这一技术的临床应用。笔者在前期研究中发现，肿瘤患 者的饮食模式有规律可循，依此规律可以将患者的饮食进行评分，从而快速了解患者饮食摄入量范围，为临床治疗的量化 打下基础。

Due to the special metabolic characteristics and the adverse reactions associated with the anti-cancer treatment, the decrease of diet in cancer patients often leads to an increase in the incidence of malnutrition, which is associated with poor clinical outcomes. Previous studies have found that the decrease of some patients’ diet easily ignored by the patients themselves and their clinical medical staffs. Dietary survey is a professional technique to demonstrate the quantity and uality patients eat. However, dietary survey needs professional dietitian to complete, which affects the clinical application. In the earlier studies, the author found that dietary patterns of cancer patients have rules to follow, in accordance with the rules, the diet of patients can be scored. Quantitative for nutrition therapy should be based on the investigation about patients’ intake.
