CEACAM5 and colorectal carcinoma: Following sequential surgical resection of the hepatic and pulmonary recurrences from CRC, the following factors are predictive of long-term survival and can help in addressing surgical strategies: 1) low CEA serum level pre-thoracotomy [7]; 2) solitary pulmonary recurrence after a long disease-free interval [3, 7]; 3) complete resection of lung recurrence after hepatic metastasectomy [5]; and 4) responsiveness to chemotherapy [2, 5].
