BackgroundPreoperative carcinoembryonic antigen (CEA) has yet to be used as a prognostic or adjuvant chemotherapy factor for colorectal cancer (CRC).MethodsThis retrospective cohort study included all stage I-III CRC patients with different preoperative serum CEA levels (5, 5-10, and>10ng/ml) at a single center between 1995 and 2010. Propensity score matching was performed in a 1:1 ratio between the two elevated CEA groups (5-10ng/ml and>10ng/ml) and in a 1:2 ratio between the elevated and non-elevated groups (5ng/ml), with a caliper of 0.05.ResultsAfter exclusion and matching, 3857 patients had preoperative CEA levels5ng/ml, 1121 patients had CEA levels between 5 and 10ng/ml, and 1121 patients had CEA levels>10ng/ml. Elevated preoperative CEA showed an increased risk of overall survival (5-10ng/ml: hazard ratio [HR] 1.376;>10ng/ml:HR1.523; both p<0.001), cancer-specific survival (5-10ng/ml: HR 1.404;>10ng/ml:HR1.712; both p<0.001), and recurrence free interval (5-10ng/ml: HR 1.190;>10ng/ml:HR 1.468; both p<0.05). Patients with negative lymph node staging (LNs) and CEA>10ng/ml, as well as those with positive LNs and CEA5ng/ml, showed similar overall survival (5-year survival: 72% vs. 69%; p=0.542) and recurrence free intervals (19.9 vs. 21.72months; p=0.662).ConclusionsA preoperative CEA level can be an independent prognostic factor for stage I-III CRC after curative resection. Patients with negative LNs and preoperative CEA level>10ng/ml should be considered for intensive follow-up or adjuvant chemotherapy.
