In cancer, PD-L1 expression inhibits immunological control leading to tumor cells avoiding immune destruction. In oral squamous cell carcinoma (OSCC), previous literature showed conflicting prognostic value of PD-L1 among studies potentially due to different clones of antibody, differences in scoring methods, and definitions of positive expression. Additionally, PDL1 could be expressed both on immune cells and cancer cells. The distribution of the cell positivity is different across different OSCC cases.
