Accuracy of Endorectal Ultrasonography and Computed Tomography for Restaging Rectal Cancer after Preoperative Chemoradiation

Abstract

ERUS and CT may allow good prediction of node-negative rectal cancers, although they are inaccurate modalities for predicting treatment response on the rectal wall. New methods of interpretation and diagnostic criteria for ERUS and CT are essential for increasing the accuracy of cancer prediction in at-risk patients.
