CEACAM5 and invasive carcinoma: Further multivariate analyses demonstrated that tumor size ≥ 49 mm (P = 0.002), MPD diameter ≥ 10 mm (P = 0.005), CA19-9 ≥ 42.7 U/mL (P = 0.005), CEA ≥ 1.9 ng/mL (P = 0.002), PLR ≥ 125 (P = 0.021), and LMR ≤ 4.29 (P = 0.001) were independent predictors of invasive carcinoma (Table 3).
