    ABSTRACT: Malnourished head and neck cancer patients are at increased risk of postoperative complications. We studied the effect of perioperative, arginine-supplemented nutritional support on nutritional status, immune status, postoperative outcome, and survival in severely malnourished (weight loss >10% of body weight) head and neck cancer patients undergoing major surgery. Forty-nine patients were randomly assigned to receive 1) no preoperative and standard postoperative tube feeding, 2) standard preoperative and postoperative tube feeding, or 3) arginine-supplemented preoperative and postoperative tube feeding. Patients in both prefed groups received approximately 9 d of preoperative tube feeding, resulting in energy intakes of 110% and 113% of calculated needs (compared with 79% in the control group; P = 0.007). Compared with no preoperative feeding, preoperative enteral nutrition did not significantly improve nutritional status or any of the studied biochemical or immunologic indexes. Major postoperative complications occurred in 53%, 47%, and 59% of patients in study groups 1, 2, and 3 (NS). A trend was seen toward better survival in the arginine-supplemented group (P = 0.15). Secondary analysis showed that survivors had better human leukocyte antigen-DR expression on monocytes (P = 0.05) and higher endotoxin-induced cytokine production (P = 0.010 for tumor necrosis factor alpha and P = 0.042 for interleukin 6) at the start of the study than did patients who died. Nine days of preoperative tube feeding, with or without arginine, did not significantly improve nutritional status, reduce the surgery-induced immune suppression, or affect clinical outcome in severely malnourished head and neck cancer patients. Patients supplemented with arginine-enriched nutrition tended to live longer. Some markers of immune function may distinguish patients with good or bad prognoses.

    ABSTRACT: Malnutrition is reported frequently in head and neck cancer patients. The impact of malnutrition on surgical outcome is not clearly understood. The purpose of this study was to define the usefulness of six different parameters in scoring malnutrition and to determine the nutritional parameter primarily related to postoperative complications. Sixty-four patients undergoing major surgery for advanced head and neck cancer were studied prospectively, and six different parameters were used to define malnutrition. Logistic regression was used to relate nutritional parameters to postoperative complications. The parameters applied all identified different aspects of the nutritional status, as malnutrition varied between 20% and 67%. Logistic regression analysis identified a weight loss of more than 10% to be the most prominent predictive parameter for the occurrence of major postoperative complications. Patients with weight loss more than 10% during the six months before surgery are at a great risk for the occurrence of major postoperative complications.
