CEACAM5 and neoplasm: In lesion-based calculations, significant differences were observed between age groups above and below 55 years (Mann–Whitney, p = 0.015); tumor grade (Kruskal–Wallis, p < 0.001); tumor size (Kruskal–Wallis, p < 0.001); and tumor markers CEA (Mann–Whitney, p = 0.017), CA19-9 (Mann–Whitney, p = 0.005), and AFP (Mann–Whitney, p = 0.001) (Figure 5).
