Nutritional support in patients with advanced cancer: permission to fall out?

Abstract

Data from the European Society for Parenteral and Enteral Nutrition Home Artificial Nutrition Survey suggest that the use of home parenteral nutrition (HPN) in patients with cancer as the primary diagnosis varies markedly between different countries in Europe, being highest in The Netherlands and low in the UK. This finding is difficult to explain on the basis of cancer incidence. The main indication for HPN remains malignant gastrointestinal tract obstruction, which occurs most frequently in gynaecological and colon cancers. The use of HPN should be planned in the light of the proposed cancer treatment and should be discussed beforehand with the patient. Before HPN is considered, a patient should typically require intravenous fluids to maintain hydration, be capable of self care, be able to control the treatment, have an expected survival of ≥3 months and have no other available route of feeding. The effect of HPN on quality of life remains controversial, but nutrition is only one of the factors that influence the quality of life in cancer patients. The differing rates of HPN in Europe are probably related to cultural attitudes to incurable cancer as much as to meeting the nutritional needs of the patient.
