Depletion of nutritional reserves and significant weight loss can lead to an increased risk of morbidity, reduced chemotherapy response, and shorter survival in patients with cancer. Weight loss and malnutrition are recognized to result from multifactorial processes, which if assessed and managed appropriately may lead to improved treatment outcome. Numerous methodologies are used for the assessment of nutritional status. However, it remains unclear which of these tools is the most appropriate in the setting of cancer chemotherapy. The aim of this study was to investigate the use of various fundamental assessment tools that could be applied to the routine clinical evaluation of nutritional status in patients with advanced solid malignancies before treatment with palliative chemotherapy. We investigated the interrelationships between biochemical indices, anthropometric measures, and a nutritional screening tool, the Mini-Nutritional Assessment, in 73 patients. Many of these measures were highly interrelated, but the baseline history of weight loss in these patients was strongly correlated to the Mini-Nutritional Assessment (MNA) score (P < 0.0005). In turn, baseline weight loss and the MNA score were strongly correlated to serum C-reactive protein (a marker of acute-phase response). In some patients, malnutrition was linked to disease- or treatment-related upper digestive tract morbidity. Testing for the serum concentration of C-reactive protein at baseline may identify a subset of patients for whom a decline in nutritional status is linked to the presence of an active inflammatory response, a recognized precursor of cachexia
营养储备的耗竭和显著的体重减轻会导致癌症患者发病风险增加、化疗反应降低以及生存期缩短。体重减轻和营养不良被认为是由多因素过程导致的,如果对其进行适当评估和管理,可能会改善治疗结果。有多种方法用于评估营养状况。然而,在癌症化疗背景下,尚不清楚这些工具中哪一种最为合适。本研究的目的是调查各种基本评估工具在晚期实体恶性肿瘤患者接受姑息化疗前营养状况常规临床评估中的应用。我们调查了73例患者的生化指标、人体测量指标与一种营养筛查工具——微型营养评定法之间的相互关系。这些指标中的许多都高度相关,但这些患者的体重减轻基线病史与微型营养评定法(MNA)评分密切相关(P < 0.0005)。反过来,基线体重减轻和MNA评分与血清C反应蛋白(急性期反应标志物)密切相关。在一些患者中,营养不良与疾病或治疗相关的上消化道发病有关。检测基线时血清C反应蛋白浓度可能会识别出一部分患者,其营养状况下降与存在活跃的炎症反应有关,而炎症反应是公认的恶病质先兆
