肿瘤营养相关状况诊断标准

营养相关状况主要指与营养或营养治疗相关的疾病总称。主要包括营养不良（营养不足）、肌肉减少症、虚弱症、超重和肥胖、微量营养素异常和再喂养综合征。本文主要介绍了肿瘤患者更为常见的营养相关状况：营养不良、恶液质、肌肉减少症及体重丢失的诊断标准。营养不良主要依据体重、体质指数（BMI）及评估量表诊断，评估方法包括主观整体评估、微型营养评价及患者主观整体评估。恶液质主要通过检测体重和骨骼肌指数、BMI诊断。肌肉减少症主要通过肌肉质量和力量及身体活动能力诊断。体重丢失主要通过体重丢失率诊断，要注意3个因素，即丢失的量、丢失的时间及丢失的成分。营养不良分为轻度、中度及重度营养不良；恶液质分为恶液质前期、恶液质期、恶液质难治期；肌肉减少症分为原发性肌肉减少症和继发性肌肉减少症；体重丢失分为0~4级。肿瘤营养相关状况诊断有利于明确肿瘤患者营养状态。

Diagnostic criteria of cancer nutrition related status

Nutrition-related conditions(NRC)mainly refer to diseases associated with nutrition or nutrition related therapies.NRC includes malnutrition(undernutrition),sarcopenit,asthenit,weight loss,over weight,fat,micronutrient abnormality and refeeding syndrome.This articla mainly introducesdiagnostie criterie of the most common nutritional status in cancer patients:malnutrition,cachexit,sarcopenit,and weight loss.Malnutrition was diagnosed by weight,BMI and Assessment Scale.The methods include subjective global assessment(SGA),mini nutritional assessment(MNA),and patient-generated subjective global assessment(PG-SGA).Cachexit was diagnosed by weight,sseletal muscl index and BMI.Sarcopenit was mainly diagnosed by muscl mass,strength and physical activity.Weight loss was mainly diagnosed by the loss ratr whose points ai the amount,the time,and the components of loss.Malnutrition includes mild malnutrition,moderatr malnutrition and severe malnutrition.Cachexia includes pre-rachexia,cachexia and bad cachexia.Sarcopenia includes primary sarcopenia and secondary sarcopenia.Weight loss includes 0 to 4 grades.The diagnosis of tumoc nutrition related status is helpful to clarify the nutritional status of tumor patients.
