Interrelationships between body composition and energy expenditure in cancer malnutrition. The role of bioimpedance assessment

Sukkar S. G., Bogdanovic A.


Aim. The aim of the experience was a case-control evaluation of the role of biological impendance assessmente (BIA) for estimating resting energy expenditure (REE) instead of indirect calorimetry (IC) in cancer patients.
Methods. Thirteen patients with gastric cancer (GK) were studied vs 18 control (C) patients. GK patients were depleted in fat free mass (FFM) (33±3 vs 44±5 kg; pResults. The REE, calculated with the Harris-Benedict formula (REE-HB) was higher in C than in GK (1 443±149 vs 1 196±109 Kcal/day; pConclusion. The group of gastric malnourished cancer patients showed an increase in REE-IC in comparison with REE-HB; the increase in REE-IC was not related to the size of the remaining BCM; it is impossible to get a satisfying linear regression function expressing REE in terms of body composition measures obtained by means of BIA instead of indirect calorimetry; the IC is more appropriate to evaluate REE in cancer malnourished patients because in the present experience the Harris-Benedict formula underestimates this parameter by more than 10% (11.06%).
