title: Randomized clinical trial with an enteral arginine-enhanced formula in early postsurgical head and neck cancer patients.
abstract: OBJECTIVE
  Patients with head and neck cancer undergoing surgery have a high incidence of postoperative complications. The aim of our study was to investigate whether postoperative nutrition of head and neck cancer patients using an arginine-enhanced formula could improve nutritional variables as well as clinical outcomes.
  
  
  METHODS
  Randomized clinical trial.
  
  
  METHODS
  Tertiary care.
  
  
  METHODS
  A population of 90 patients with oral and laryngeal cancer was enrolled.
  
  
  METHODS
  At surgery, patients were randomly allocated to two groups: (a) patients receiving an arginine-enhanced formula with arginine and fiber (group I) and (b) patients receiving an isocaloric, isonitrogenous formula with fiber enteral formula (group II).
  
  
  RESULTS
  No significant intergroup differences in the trend of the three plasma proteins (albumin, transferrin, prealbumin) and lymphocytes were detected. Gastrointestinal tolerance (diarrhea) was better in group II than I (40% group I and 13% group II: P<0.05). The postoperative complications due to infections were similar in both groups (4% group I and 9% group II: ns). Fistula (wound complication) was less frequent in the enriched nutrition group (5% group I and 11% group II: P<0.05); wound infection was similar in both groups. The length of postoperative stay was better in group I than II (25.8+/-15 days vs 35+/-24.6 days; P<0.05).
  
  
  CONCLUSIONS
  In conclusion, arginine-enhanced formula improves fistula rates in postoperative head and neck cancer patients and decreases length of stay.
