The association of nutritional assessment criteria with health-related quality of life in patients with advanced colorectal carcinoma.

Health-related quality of life (QoL) is a goal in nutritional oncology but the association between nutritional status and QoL is rarely explored. The aim of the study was to investigate the association of nutritional assessment criteria with QoL in 50 patients with advanced colorectal carcinoma. A second aim was to investigate changes in body weight and QoL during a 3-month follow-up. Muscle mass, nutritional risk, malnutrition and cachexia according to three different criteria were assessed, as well as health-related QoL. At inclusion, 36 patients experienced weight loss, 10 patients sarcopenia, 25 were at nutritional risk, 16 were malnourished and 11, 14 and 31 patients had cachexia according to different criteria. All nutritional assessment criteria discriminated between groups of patients with worse or better QoL to varying degrees. Malnutrition and cachexia defined by the European Palliative Care Research Collaborative and adjusted for recent gain or stabilisation of body weight discriminated on most QoL scores. Weight loss at follow-up was associated with a decrease in several QoL scores. Recognition of weight loss as well as diagnosing malnutrition and cachexia should be the first steps in an interventional pathway to enhance nutritional status and QoL in patients with advanced colorectal carcinoma.
