Endoscopic ultrasound in early gastric cancer: Diagnostic accuracy and Tis/T1a lesion over staging risks

Key Points

Diagnostic accuracy of endoscopic ultrasound is notably decreased for Tis/T1a early gastric cancer when gastric ulcers are present.
Findings indicate that staging should be approached with caution when dealing with ulcer-related lesions.
Endoscopic ultrasound is used for cancer staging, but its effectiveness varies with the presence of ulcers.
Caution in EUS interpretation is emphasized for accurate clinical decision-making regarding treatment options.

Abstract

The accuracy of EUS for staging Tis/T1a early gastric cancer is markedly reduced when gastric ulceration is present. Therefore, EUS-based staging should be interpreted cautiously in patients with ulcer-related lesions.
