Sanchez-Canteli et al. demonstrated that although CLEC2D immunoreactivity in carcinoma cells correlated with poorer prognosis in HPV-negative oropharyngeal squamous cell carcinomas, the prognostic impact of CLEC2D mRNA levels from The Cancer Genome Atlas (TCGA) varied by HPV status and cancer type [12]. Here, CLEC2D is linked to carcinoma.
