Brief Summary:
Background There is currently no reliable means to restage rectal cancers after neoadjuvant chemoradiation. There are still no reliable methods to identify patients with pCR before radical surgery. As a result, clinical complete response (cCR), defined as no clinical detectable tumor by physical examination, endoscopic evaluation, and imaging, is designed as a surrogate endpoint for pCR. However, the concordance between cCR and pCR varies from 22% to 96% in different reports, which questions the clinical value of such strategies. Therefore, based on rectal diginal examination, serum CEA, MRI, endoscopy examination, we suggested to add multi-points and full-thickness biopsy technique to further improve the accuracy of cCR.
