Guidelines Issued by United States Professional Societies

Society	Year	Recommendation
Gastric Cancer Screening
American Society of Gastrointestinal Endoscopy⁷⁰	2015	Endoscopic screening for gastric cancer in first-generation immigrants from high-risk regions (e.g. Japan, China, Russia, and South America) may be considered for those aged 40 years, particularly if there is a family history of gastric cancer in a first-degree relative
Surveillance of Intestinal Metaplasia (IM)
American Society of Gastrointestinal Endoscopy^{14, 70}	2015	Endoscopic surveillance in patients with gastric atrophic gastritis or IM coupled with an increased risk of gastric cancer because of racial/ethnic background, extensive anatomic distribution, or family history
American Gastroenterological Association⁷¹	2019	Recommends against routine use of endoscopic surveillance in patients with IM. Conditional recommendation, very low quality of evidence Patients with IM at higher risk for gastric cancer who put a high value on potential but uncertain reduction in gastric cancer mortality, and who put a low value on potential risks of surveillance endoscopies, may reasonably elect for surveillance. Patients with IM specifically at higher risk of gastric cancer include those with: Incomplete vs complete IM Extensive vs limited IM Family history of gastric cancer Patients at overall increased risk for gastric cancer include: Racial/ethnic minorities Immigrants from high incidence regions

Existing recommendations from United States-based professional societies regarding screening of gastric cancer or surveillance of precancerous lesions such as intestinal metaplasia (IM).
