A recent study showed that the expression of PDL1, B7‐H3 and VISTA as well as some tumor necrosis factor receptor superfamily such as OX40L, CD27, 4‐1BB, CD40, and CD95/Fas were correlated with the head and neck squamous cell carcinoma immunotherapy efficiency, and could serve as potential biomarkers to predict the immunotherapy response.244. Here, FAS is linked to head and neck squamous cell carcinoma.
