As shown in Table 3, tumor size (HR: 1.022, 95% CI: 1.001–1.043, p = 0.045), CA 19-9 (HR: 1.021, 95% CI: 0.095–1.024, p = 0.017), and IRE plus PD-1/PD-L1 blockade treatment (HR: 2.217, 95% CI: 1.161–5.034, p = 0.018) were significantly correlated with OS in the univariate Cox regression analysis. Here, CD274 is linked to neoplasm.
