As is shown in Figure 7, we found in ICC patients without BTS, NLR values (P < 0.001 and P < 0.001, respectively), SII values (P < 0.001 and P = 0.004, respectively), SIRI values (P = 0.005 and P = 0.008, respectively) were negatively associated with CD8+/CD3+ lymphocytes ratio and PD1+/CD3+ lymphocytes ratio, and PLR values (P = 0.005) and SIRI values (P = 0.039) were positively correlated with PD-L1 levels. Here, CD8A is linked to intrahepatic cholangiocarcinoma.
