CSF2 and head and neck squamous cell carcinoma: A novel prognostic model of HNSCC patients based on six-NET-related genes (Annexin A3 (ANXA3), lactotransferrin (LTF), colony-stimulating factor 2 (CSF2), glyceraldehyde-3-phosphate dehydrogenase (GAPDH), selectin P ligand (SELPLG), and cytochrome b-245 beta chain (CYBB)) was constructed that might be beneficial for developing personalized treatment directed at neutrophils (110).
