Postoperative median pCEA levels of CRC patients were significantly higher compared to benign patients (5.4 vs. 2 ng/ml, <italic>P</italic> = 0.011). Specifically, pCEA levels in CRC patients were significantly elevated when measured during the first 24 hr after surgery.</p> <p>Postoperative pCEA levels were associated with colon tumor location compared to rectal location.

Its significance within patient's prognostic evaluation remains to be studied. Inclusion of patient's follow‐up data may reveal the significance of elevated pCEA levels following CRC resection. <italic>J. Surg.
