Abstract

Purpose: Malnutrition is highly prevalent in head and neck cancer (HNC) patients, with weight loss being one of the major nutritional indicators. The objective of this study was to investigate the impact of weight loss on treatment interruptions and unplanned hospital admissions in HNC patients undergoing radiotherapy (RT) with or without chemotherapy.

Methods: In this retrospective cohort study, consecutive HNC patients who started RT between January 2011 and December 2019 were included. Data from a total of 1086 subjects with 747 (68.8%) nasopharyngeal carcinomas (NPCs) and 31.2% (N=339) non-NPC patients were analysed. Body weight (BW) was measured before, during, and after RT treatment. Factors associated with ≥10% weight loss, treatment interruption, and unplanned admissions were analysed using multivariate logistic regression.

Results: The prevalence of ≥10% weight loss was 26.8% (N=288), with 32.7% (N=243) in NPC and 13.5% (N=45) in non-NPC patients. The prevalence of RT delay in patients with ≥10% vs. <10% weight loss was 6.2% vs. 7.0% (p=0.668) in NPC patients and 42.2% vs. 50.5% (p=0.300) in non-NPC patients. The prevalence of unplanned admissions in patients with ≥10% vs. <10% weight loss was 51.9% vs. 25.3% (p<0.001) in NPC patients and 68.9% vs. 27.0% (p<0.001) in non-NPC patients.

Conclusion: In our study, ≥10% weight loss was found to be associated with a higher rate of unplanned admissions but not with RT delay or chemotherapy interruption.

Clinical Implications: With the knowledge of the impact of weight loss on hospital admissions and the characteristics of patients with weight loss, nutritional intervention can be effectively focused on the stratification of patients for intensive nutritional support to reduce weight loss.
