In patients without inflammation, univariate analyses identified that a worse OS was significantly associated with older age (p = 0.011), poor ASA-PS (p = 0.002), large tumor size (p < 0.001), poor differentiation (p = 0.001), advanced pTNM stage (p < 0.001), high CEA level (p = 0.001), high SII (p = 0.002), high NLR (p < 0.001), high PLR (p < 0.001), and postoperative adjuvant chemotherapy (yes) (p < 0.001). Here, CEACAM5 is linked to neoplasm.
