Task: Answer Verification
Input (English): Question: Does the Seattle protocol more reliably predict the detection of cancer at the time of esophagectomy than a less intensive surveillance protocol?
Answer: Intense preoperative biopsy sampling by the Seattle protocol does not more reliably predict the detection of cancer at the time of esophagectomy than a less intensive surveillance protocol. This calls into question the concept that extensive sampling with the Seattle protocol consistently detects early cancers arising in Barrett's esophagus patients with high-grade dysplasia.
Output (English): no
