Abstrakt: Expression of the family with sequence similarity 3 member C (FAM3C) is necessary for the epithelial-mesenchymal transition (EMT). However, the expression level and clinicopathological significance of FAM3C in oral squamous cell carcinoma (OSCC) has not been thoroughly elucidated to date. We performed immunohistochemical staining on human OSCC specimens with FAM3C, co-inhibitory immune checkpoints, EMT markers, and cancer stem cells (CSCs) markers to analyze the expression levels and clinicopathological features of FAM3C in OSCC. There were 210 primary OSCC specimens, 69 oral epithelial dysplasia and 42 normal oral mucosae in our human OSCC tissue microarrays cohort. We observed that FAM3C expression was upregulated in OSCC compared with normal mucosa and epithelial dysplasia (P <  0.001). Moreover, patients with higher FAM3C expression levels had a worse prognosis than those with lower expression levels (P < 0.05). Also, FAM3C expression was positively correlated with the immune checkpoints PD-L1, VISTA, and B7-H4, the EMT marker Slug and the CSC markers SOX2 and ALDH1. In conclusion, these findings suggested that overexpression of FAM3C in human OSCC may predict a poor prognosis for OSCC patients.
