Relationship between nutritional status and quality of life in patients with cancer

Patients with cancer frequently suffer a deteriorated quality of life and this is an important factor in the therapeutic decision. The correlation between quality of life and malnutrition seems obvious and bidirectional. The aim of our study was to describe the global quality of life and its various dimensions in patients with cancer, as a function of the nutritional status.A transversal observational study was performed in wards in hospitals in Clermont Ferrand and Saint Etienne on 907 patients. The EORTC questionnaire, QLQ-C30, was used to assess the quality of life.The mean global quality of life score was 48.8 for patients who had a weight loss of more than 10% since the beginning of their illness, compared with 62.8 for the other patients (p < 0.001). A significant association with weight was observed for the main dimensions of the quality of life: physical, functional, cognitive, social, fatigue, nausea, pain, loss of appetite, constipation and diarrhoea. This strong relation between quality of life and weight loss shows the importance of dietary management in patients with cancer.
