Use of Carcinoembryonic Antigen Radioimmunodetection and Computed Tomography for Predicting the Resectability of Recurrent Colorectal Cancer

The accuracy of arcitumomab for assessing resectability status is greater than that of CT, both in all patients undergoing evaluation for curative abdominopelvic resection of colorectal cancer and in the subset of patients with suspected or proven liver metastases. The additional use of arcitumomab with CT potentially doubles the number of patients who could be saved the cost, morbidity, and mortality of unnecessary abdominopelvic surgery and increases those who are potentially resectable for cure by 40%.
