As illustrated in Figure 2, by adding up the points identified on the points scale, the nomogram can provide the risk for a PDAC patient to be diagnosed with liver metastasis.16 The C‐index for this nomogram (0.970) was superior to that of CT estimation alone (0.930), tumor differentiation type (0.680), and CEA level (0.670). The gene discussed is CEACAM5; the disease is neoplasm.
