CEACAM5 and colorectal carcinoma: Our analyses of a retrospective, multicenter longitudinal cohort of patients with stage I–III CRC who underwent curative resection showed that the association between serum CEA levels and CRC outcomes varied at different perioperative time points, and CEApost-m2–3 was more informative than CEApre-m1, CEApost-m1, and CEApost-m4–6.
