The association between nutrition impact symptoms, nutritional risk, and risk of reduced overall survival in patients with head and neck cancer. A retrospective study

Abstract

Background & aims: To examine which nutritional impact symptoms (NIS) were most prevalent at the initial state of treatment in outpatients with head and neck cancer (HNC). Secondly, to examine whether there is a potential relation between risk of reduced overall survival to NIS or nutritional risk.

Methods: Retrospective data collection from outpatients with HNC undergoing radiotherapy and/or systemic therapy. A clinical dietitian consulted all patients with the inclusion of a nutritional risk screening according to the Nutritional Risk Screening tool (NRS 2002) and Eastern Cooperative Oncology Group performance status (ECOG), and an assessment of NIS collected with a structured questionnaire, with the prevalence of 16 symptoms and to what degree they were nutritionally limiting. Weight loss at two months follow-up was calculated and patients were categorized as either at low or high risk of reduced overall survival in accordance with a BMI-adjusted weight loss grading system (high, score 0-2; low, score 3-4).

Results: A total of 110 patients were included (male, 77%; age, 66 (59-71)). The mean weight loss was 4.5 kg at two months follow-up, increasing with higher BMI. Eighty-six percentage of the patients experienced 3 or more of the present NIS (P-NIS), and 44% of the patients experienced 3 or more of the nutritionally limiting NIS (L-NIS). Patients who have a high risk of reduced overall survival accounted for 45% and consisted of patients with low BMI and high percentual weight loss. No significant difference was found between the two groups in terms of NIS.

Conclusion: We found NIS to be highly prevalent among patients with head and neck cancer. Women experienced more NIS than men. Half of the patients were categorized as being at high risk of reduced overall survival, but no relation between the risk of reduced overall survival to NIS or nutritional risk was found in this study.
