PD-L1 status in correlation with overall survival in cholangiocarcinoma patients. PD-L1 immunohistochemistry results using clone SP263 were correlated with overall survival of CCA patients. Kaplan-Meier curves show a trend of decreased overall survival in CCA patients with any PD-L1 positivity in tumor cells (p = 0.09; a). Significant decreased overall survival rates are seen in CCA patients with PD-L1 positivity in > 5% of tumor cells (p < 0.001; b). PD-L1 positivity in stromal cells has no impact on overall survival of CCA patients in none vs any (p = 0.89; c) or testing the cut-off of 5% (p = 0.69; d)
