CEACAM5 and neoplasm: In the univariate analyses, age (p < 0.001), ASA grade (p = 0.002), BMI (p = 0.001), CEA (p = 0.001), tumor size (p = 0.023), LVI (absent vs. present, p < 0.001), number of retrieved LNs (p = 0.031), AJCC stage (I and II vs. IV, p < 0.001), postoperative chemotherapy (p < 0.001), BLR (p < 0.001), and SLR (p = 0.030) were significantly associated with OS (Table 2).
