However, it would appear that a core set of pathways (TP53, RB1/cell cycle, and PI3K/AKT/mTOR) is compromised in both HPV+ and HPV- oropharyngeal tumors, thus targeted therapies directed against one or more of these pathways could be efficacious in both contexts. This evidence concerns the gene TP53 and neoplasm of oropharynx.
