  • High PD-L1 expression is associated with distant metastasis and decreased overall survival of oral squamous cell carcinoma (OSCC) patients.

Key results

  • High PD-L1 expression was independently associated with reduced overall survival in male patients and patients who smoke in multivariate analysis (p=.0077 and p=.0004, respectively).
  • High PD-L1 was significantly associated with distant metastasis (p=.0103).
