Negative Biopsy after Referral for Biopsy-Proven Gastric Cancer

BACKGROUND/AIMS Repeat endoscopy with biopsy is often performed in patients with previously diagnosed gastric cancer to determine further treatment plans. However, biopsy results may differ from the original pathologic report. We reviewed patients who had a negative biopsy after referral for gastric cancer. METHODS A total of 116 patients with negative biopsy results after referral for biopsy...
