Clinical Outcomes of Endoscopic Resection for Treating WHYX Lesion

Endoscopically, WHYX cancers demonstrated a vague extent of tumor spread due to pale color changes in both the background atrophic and metaplastic gastric mucosa. However, the clinical outcomes of WHYX cancers after endoscopic resection are unknown. The aim of this study was to evaluate clinical outcomes of WHYX cancers after endoscopic resection.
