[Good clinical practice in nutritional management in cancer patients: malnutrition and nutritional assessment].

Abstract

The main recommendations for the nutritional evaluation of cancer patients are: 1) Clinical and anthropometric evaluation should measure height, current weight, ideal weight, weight lost and rate of loss, and Body Mass Index. Social and economic data, details of previous history, current treatment and clinical examination results should also be collected. Gastrointestinal disorders and energetic needs should be assessed. 2) Nutritional intervention is recommended for all patients with a weight loss of 10% or more. 3) A multidimensional assessment can be performed using three validated nutritional and clinical scales: the Subjective Global Assessment, the Scored PG-SGA and the Mini Nutritional assessment. 4) The predictive value of biological factors (albumin) is not sufficient individually, risk scales combining several factors should be used: the Prognostic Inflammatory and Nutritional Index (PINI), the Nutritional Risk Index (NRI), the Prognostic Nutritional Index (Mullen) or the Sadan. 5) Minimal nutritional assessment should include clinical data, patient interview, height, current weight, ideal weight and weight change. 6) The efficacy of the nutrional management should be followed by assessing weight, and the presence of oedema and ascitis. The ratio of calorie to nitrogen intake should be calculated regularly.
