title: [Evaluation of nutritional Status in lung cancer using bio electrical impedance analysis and mini nutritional assessment].
abstract: BACKGROUND
  Malnutrition and cachexia were a frequent problem in lung cancer and increases the risks of morbidity and mortality in these patients. Bioelectrical impedance analysis (BIA) is easy, non-invasive and reproducible method that can be performed.
  
  
  OBJECTIVE
  Evaluate nutritional status in patients with primary lung cancer by Mini Nutritional Assessment (MNA), BIA and anthropometric values (weight, arm and calf circumferences) and correlate the nutritional parameters to severity of cancer and histopathology.
  
  
  METHODS
  The nutritional status of 73 cases of primary lung cancer was evaluated by anthropometric parameters, MNA test and impedencemetrie Results: According to body mass index (BMI), malnutrition, overweight and obesity were noted in 34,2%, 13,7% and 5,5%. According to BMI, free-fat mass index (FFMI) and fat mass index (FMI), the investigations occurred malnutrition and depletion of muscle in respectively 19,2% and 23,3% of cases. Fat depletion was noted in 21,9%. Overweight and obesity were detected in 6,8% and 5,5% of cases. Assessment by MNA, revealed that 28,7% of patients were already malnourished and 49,3% of patients were at risk of malnutrition. A significant correlation existed between the score of MNA and arm and calf circumferences, FFMI and FMI. FMI was significantly lower in group of patients with small lung carcinoma.
  
  
  CONCLUSIONS
  Only FFMI allows early detection of malnutrition in cancer patients overestimated by measuring BMI and arm circumference was the better indicator of depletion of muscle.
