Metastatic oral cavity squamous cell carcinoma had 0.00-fold higher JUN gene expression than non-metastatic oral cavity squamous cell carcinoma (*p* = 0.000) (Fig. [0](#Fig0){ref-type="fig"}). Figure [0](#Fig0){ref-type="fig"} compares JUN expression in oropharyngeal squamous cell carcinoma in patients without metastatic events at 0 years with that of patients with metastatic events at 0 years \[[@CR00]\]. Metastatic oropharyngeal squamous cell carcinoma had 0.00-fold higher JUN gene expression than non-metastatic oropharyngeal squamous cell carcinoma (
