The AUC of the ROC curves of these independent factors including tumor size ≥ 49 mm, MPD diameter ≥ 10 mm, CA19-9 ≥ 42.7 U/mL, CEA ≥ 1.9 ng/mL, PLR ≥ 125, and LMR ≤ 4.29 curves were 0.617, 0.595, 0.664, 0.722, 0.691 and 0.667, respectively (Figure 2B). This evidence concerns the gene CEACAM5 and neoplasm.
