摘要： 身体组分是评价肿瘤患者营养状况的重要参考指标。本文总结了常用的测量身体组分的方法，归纳了肿瘤患者 身体组分评估的临床价值和应用前景。CT 和 MRI 具有较高的组织分辨率和测量准确性，是身体组分评价的金标准。身体 组分可以预测患者对治疗的耐受性；基于身体组分的营养评估，如内脏肥胖、肌肉减少症和肌肉减少性肥胖被认为是肿瘤 患者的不良预后因素。身体组分有望成为肿瘤治疗副反应和生存的预测因子，但其临床应用还需要大规模临床试验证实和 多学科合作。

Abstract: Body composition is an important reference for evaluating nutritional status of cancer patients. We summarized the various methods of body composition assessment and its clinical applications in oncology. CT and MRI are the current gold standard in body composition evaluation with its high spatial and contrast resolution. Body composition can be used to predict chemotherapy tolerance; Nutrition evaluation based on body composition such as visceral obesity, sarcopenia and sarcopenia obesity are considered to be adverse prognostic factors in cancer patients. Body composition may be a significant predictor of treatment toxicities and prognosis, but its clinical application needs multidisciplinary cooperation and more well-designed prospective clinical trials.
