[Value of a nutrition score in patients with advanced carcinomas in the area of the head and neck]

Abstract

Background and objective: Patients with advanced head and neck cancer often suffer from malnutrition even before the start of therapy. Hence, the demand for nutritional support increases particularly before and during radiochemotherapy. Though nutritional therapy has been shown to substantially improve individual outcome, neither the criteria for patient candidacy nor the indications for therapeutic intervention have been established. We performed a retrospective analysis to determine the indications for nutritional support and < 0 evaluate the benefits of measures actually taken against malnutrition before and during radiochemotherapy as well as perioperatively.

Patients/methods: Data taken from a prospective study for the evaluation of oral mucositis during radiochemotherapy was analysed retrospectively. To calculate the indication for nutritional support, a nutritional scoring system (Hackl) was employed for the first time, which contained biochemical and anthropometric parameters as well as the period of starvation. The results were then compared to a nutritional support program implemented by the subjective examinations of the attending physician.

Results: Changes in body weight and body mass index (BMI) remained the most impressive parameters. Catabolic metabolism developed preoperatively and a significant loss of whole-body protein followed surgical therapy. Clinically, the results of the nutritional score correlated with the observation of malnutrition. Furthermore, our findings suggest that nutritional therapy was commonly delayed until late in the clinical course.

Conclusion: The results indicate the necessity of objective and reproducible diagnosis and control of malnutrition. The scoring system used may provide a useful and yet simple tool for assessing individual indications for timely nutritional support.
