The results of a correlation analysis suggested that the number of tumor-infiltrating N1 neutrophils was high (P < .001) and that the number of N2 neutrophils was low (P < .001) in ICC patients with an FGFR2 fusion/rearrangement (Table 2; Figure 4C). This evidence concerns the gene FGFR2 and intrahepatic cholangiocarcinoma.
