Indeed, we have been previously reported that the low expression of SLC7A11 predicted short OS as well as DFS in a smaller cohort of 489 OC patients (81); and low levels of VCP in HPV-negative patients was related to worse 5-year DFS in oropharyngeal squamous cell carcinoma (82). Here, SLC7A11 is linked to oropharynx squamous cell carcinoma.
