EGFR and head and neck squamous cell carcinoma: NK2 homeobox 3 (NKX2-3), Fas-associated death domain protein (FADD), parkin RBR E3 ubiquitin protein ligase (PARK2), and epidermal growth factor receptor (EGFR) have been identified as potential prognostic markers associated with autophagy in the tumorigenesis of head and neck squamous cell carcinomas [46,47].
