PD-L1 status in correlation with patient overall survival in cholangiocarcinoma subtypes. PD-L1 immunohistochemistry (clone SP263) results are correlated with overall survival of CCA patients, stratified by CCA subtypes. In intrahepatic CCA (iCCA), Kaplan-Meier curves show no significant overall patient survival difference in correlation with none vs any PD-L1 positivity in tumor cells (a), while significant decreased overall survival rates are seen in iCCA patients with PD-L1 positivity in > 5% of tumor cells (p = 0.024); (b)). In perihilar CCA (pCCA), Kaplan-Meier curves show no significant overall patient survival difference in correlation with none vs any PD-L1 positivity in tumor cells (c), while by trend decreased overall survival rates are in pCCA patients with PD-L1 positivity in > 5% of tumor cells (p = 0.060; (d)). PD-L1 positivity in distal CCA (dCCA) has no impact on overall patient survival in none vs any (e) or testing the cut-off of 5% (f)
