Key inclusion criteria

Patients who underwent surgical or endoscopic resection at participating institutions between January 1, 2010 and December 31, 2020, and were histologically diagnosed as gastric adenocarcinoma of fundic gland type (e.g., gastric adenocarcinoma of fundic gland type, gastric adenocarcinoma of fundic gland mucosal type) with a confirmed depth of submucosal invasion.

Key exclusion criteria

Patients with a history of cancer of the stomach or other organs within 3 years of surgery. However, the following cancers, which are considered to have almost no chance of having metastasis, are not included in the exclusion criteria
1) EP/LPM cancer of the esophagus
2) M cancer of the colon
3) Differentiated M carcinoma of the stomach less than 2 cm without ulcerative changes
