- Abstract
Background: Hypoxia is a negative prognostic factor in head and neck squamous cell carcinomas. Under hypoxia, the hypoxia‐inducible factor (HIF)‐1a transcription factor is overexpressed. We investigated whether there were site differences in HIF‐1a expression and its effect on patient outcomes per subsite. Design/Method: A total of 941 patients with HNSCC in the squamous cell carcinoma of the oropharynx (OPSCC, n = 302), oral cavity (OSCC, n = 391), or larynx (LSCC, n = 248) were included. Expression of HIF‐1a in tissue samples was investigated using immunohistochemistry. Overall survival (OS), disease‐free survival (DFS), and locoregional control (LRC) were analyzed. Results: HIF‐1a expression was higher in OSCC than in LSCC and OPSCC. High HIF‐1a expression led to worse prognosis in OPSCC (OS P =.029, DFS P =.085) and LSCC (OS P =.041, DFS P =.011) and better in OSCC (OS P =.055, DFS P =.012). There was no association between HIF‐1a and LRC. Conclusions: High HIF‐1a expression is related to poor outcome in OPSCC and LSCC and better outcome in OSCC.
