Local recurrence and distant metastasis rates were not significantly different in gender (male vs. female), preoperative CEA levels (≤5ng/ml vs. >5mg/ml), histology (grade I vs. grade II vs. grade III), and mucin production (mucinous adenocarcinoma vs. adenocarcinoma not otherwise specified). Here, CEACAM5 is linked to colon mucinous adenocarcinoma.
