Task: Answer Verification
Input (English): Question: Does response evaluation by endoscopy , rebiopsy , and endoscopic ultrasound accurately predict histopathologic regression after neoadjuvant chemoradiation for esophageal cancer?

The diagnostic accuracy of endoscopy, rebiopsy, and EUS is inadequate for objective response evaluation after neoadjuvant chemoradiation and can be omitted for this purpose in the clinical practice.
Output (English): no
