ABSTRACT Background xCT, also known as SLC7A11 (solute carrier Family 7 Member 11), is a cystine/glutamate antiporter protein that mediates regulated cell death and antioxidant defense. The aim of this study was to investigate the effect of xCT on the outcome of patients diagnosed with new head and neck squamous cell carcinoma (HNSCC). Methods This retrospective cohort study utilized a population‐based dataset, comprising all patients (n = 1033) diagnosed with new HNSCC during 2005–2015 in a population of 697,000 people. All patients (n = 585) with a tumor tissue sample available for immunohistochemical (IHC) staining were included. The follow‐up rates were 97% and 81% at 3 and 5 years, respectively. Also, the specificity of the anti‐xCT antibody was validated. Results The expression level and prognostic significance of xCT were strongly dependent on tumor location. In oropharyngeal squamous cell carcinoma (OPSCC) patients, xCT expression was a significant prognostic factor for 5‐year overall survival (OAS) (HR: 2.71; 95% CI 1.67–4.39; p |
