In patients suffering from advanced neoplastic disease, malnutrition is a common complication affecting both the survival and quality of life. In order to monitor early dietary interventions, an assessment of patients' nutritional status is essential. We assessed the nutritional status of 46 patients using two different methods: 1) an objective method of nutritional assessment and 2) the subjective global assessment (SGA) technique. It was found that 28 patients were characterized as malnourished by means of the objective method and 30 patients according to the SGA. The correlation of the results of the assessments between the two methods was high and a validation test of the SGA gave a sensitivity of 96% and specificity of 83%. The most frequent symptoms affecting food intake were anorexia, early satiety, dry mouth, pain and nausea. The results show that the SGA represents an easy method for assessment of the nutritional status in such cancer patients and that it can therefore be used as a screening tool. The high incidence of malnutrition in this group of patients, and their rare use of nutrient supplements, both indicate the importance of early nutritional assessment, and nutritional intervention when appropriate.
在患有晚期肿瘤疾病的患者中，营养不良是一种常见的并发症，会影响患者的生存和生活质量。为了监测早期饮食干预措施，评估患者的营养状况至关重要。我们使用两种不同方法评估了46例患者的营养状况：1）营养评估的客观方法；2）主观全面评定（SGA）技术。结果发现，通过客观方法判定28例患者为营养不良，根据SGA判定30例患者为营养不良。两种方法评估结果的相关性很高，SGA的验证试验敏感性为96%，特异性为83%。影响食物摄入的最常见症状是厌食、早饱、口干、疼痛和恶心。结果表明，SGA是评估此类癌症患者营养状况的一种简便方法，因此可作为一种筛查工具。该组患者营养不良的高发生率以及他们很少使用营养补充剂，均表明早期营养评估以及在适当的时候进行营养干预的重要性。
