Purpose: We assessed the presence of salivary cytokines, their modulation during chemoradiation therapy (CTRT), and their association with oral mucositis severity in patients with head and neck cancer (HNC). Methods and Materials: The present prospective observational study enrolled 55 patients with locally advanced HNC requiring CTRT. We also studied 10 healthy volunteers and 10 patients with other cancers. The salivary levels of 13 cytokines were analyzed. We constructed a cytokine predictive score of oral mucositis severity.

Abstract

Purpose: We assessed the presence of salivary cytokines, their modulation during chemoradiation therapy (CTRT), and their association with oral mucositis severity in patients with head and neck cancer (HNC). Methods and Materials: The present prospective observational study enrolled 55 patients with locally advanced HNC requiring CTRT. We also studied 10 healthy volunteers and 10 patients with other cancers. The salivary levels of 13 cytokines were analyzed. We constructed a cytokine predictive score of oral mucositis severity. Results: The baseline salivary cytokine levels were not associated with the severity of treatment-induced oral mucositis. The cytokine levels overall increased during treatment, especially in patients with worse mucositis. In particular, on univariable analysis, an increase of interleukin (IL)-1 beta (area under the curve [AUC] 0.733; P=.009), IL-6 (AUC 0.746; P=.005), and tumor necrosis factor-alpha associated with the severity of mucosal toxicity. A greater increase of IL-1 beta and IL-6 3 weeks after treatment initiation is predictive of worse oral mucositis, representing a potential tool for the early identification of patients at risk. (C) 2016 Elsevier Inc. All rights reserved. (AUC 0.710; P=.005) at the third week of treatment was significantly associated with the development of severe oral mucositis.
