Indications for endoscopic resection of early gastric cancer

Indications for endoscopic resection of early gastric cancer
Absolute indications (all of the following):
  • Histology: Differentiated
  • Size: ≤20 mm
  • Ulceration: None
  • Tumor type: Intestinal
  • No suspected lymphovascular invasion
Expanded indications (any of the following):
  • Mucosal tumors >30 mm, differentiated type, and without ulceration
  • Mucosal tumors <30 mm in size, differentiated type, with ulceration
  • Mucosal tumors ≤20 mm, undifferentiated type, without ulceration
  • Submucosal tumors <30 mm invading less than 500 micrometer into the submucosa without lymphovascular invasion
The absolute indication for endoscopic resection originated from identifying risk factors for lymph node metastases, which were determined after evaluating surgically resected specimens. Use of the expanded criteria for curative endoscopic management remains investigational. Patients with tumors that do not have absolute indications, but who cannot undergo surgery because of comorbidities, have relative indications for endoscopic resection.
