Background: Metabolic reprogramming and abnormal glucose metabolism are hallmarks of head and neck squamous cell carcinoma (HNSCC). Certain oncogenes can promote cancer‐related metabolic changes, but understanding their crosstalk in HNSCC biology and treatment is essential for identifying predictive biomarkers and developing target therapies. Methods: We assessed the value of survivin/BIRC5 as a radioresistance factor potentially modulated by glucose for predicting therapeutic sensitivity and prognosis of HNSCC in a cohort of 32 patients. Additionally, we conducted in vitro experiments to explore the role of survivin/BIRC5 in glucose metabolism concerning radiation response. Results: Tumoral BIRC5 expression is associated with serum glucose and predicts locoregional disease‐free survival and lower BIRC5 mRNA levels are associated with better outcomes. Upregulation of BIRC5 by radiation depends on glucose levels and provokes a pro‐tumoral and radioresistant phenotype in surviving cells. Conclusions: Survivin/BIRC5 might be independently associated with the risk of recurrence in patients with HNSCC. [ABSTRACT FROM AUTHOR] |
