RESUMO
OBJECTIVE: Authors reported the results of a study on the application of immunonutrion in peri-operative (pre and postoperative) in head and neck cancer for all patients malnourished or not. In preoperative we used an oral treatmentand in postoperative an enteral one. MATERIALS AND METHODS: Prospective study concerning 78 patients (47 malnourished versus 31 not) having had heavy head and neck curative cancerology surgery. The mean follow up was of 10 months (from 7 to 16 month). They peri-operative immuno-enriched diet consisted, in pre-operative of 1000 kcal/j during 7 days of oral immunonutrition (Impact), and in post-operative, 1500 kcal/j during 10 days of enteral immunonutition (Crucial). The nutritional state was evaluated in pre-operative by simple clinical and biological parameters (size, weight, CMI "Corporal Mass Index", albumin, NRI "Nutritional Risk Index"), and in post-operative by the evolution of the weight and the CMI. The palatability of the product used in pre-operative and the patients' compliance to the treatment are studied using the satisfaction's multiple choice question paper. RESULTS: The study showed an improvement of the patients' nutritional and general state (regain appetite, less marked asthenia) and of the quality of life. The product used in preoperative was well tolerated, this oral supplementation led to the same beneficial effects of the enteral's. At eight days in preoperative, the average weight was 62.35 kg, the average CMI was 20.93, and the average NRI was 94.12. In post-operative the patients' nutritional state improved: at eight days, the average loss of weight was 2.82 kg, the average CMI was 22.2. At one and six months after respectively the average gain of weight was 2.17 kg and 6.11 kg, the average CMI was 23.71 and 25.16. The application of this protocol decreased the post-operative complications (13% reduction of the infectious complications and 6% diminution of the fistulas). The time of hospitalization is then reduced (1.7 days), and the life's longevity is improved. CONCLUSION: The results produced by this study, demonstrate the necessity to apply a peri-operative immuno-enriched diet systematically for all the patients with and without a degraded nutritional state, undergoing a heavy head and neck curative cancerology surgery.
