42 Background: Gastric cancer development is multifactorial with varying incidence rates. People of Korean heritage have the highest rate of gastric cancer in the world and among Americans. While this gastric cancer disparity is well known, an evaluation of the population-specific risk factors and the effectiveness of selective screening in the Korean American communities have not been studied. Methods: Korean Americans living in Northern New Jersey over 40 years of age without a known history of gastric cancer were eligible to participate in this prospective study. Each participant received a 30-minute one-to-one consultation with a gastric cancer surgeon, given a 44-item questionnaire, and underwent an upper endoscopy with biopsies. The consultation included assessment for the presence of relevant history, symptoms, and signs. The questionnaire addressed patient-specific demographic, epidemiologic, and cultural information. Two gastroenterologists blinded to the consultation and questionnaire results performed the upper endoscopies. Results: Between September 2013 and September 2014, one hundred participants enrolled in our study. All participants denied the presence of alarm symptoms, such as acute weight loss, melena or persistent vomiting. Risk factors, including prior H. pylori infection (25%), family history of gastric cancer (15%), cigarette smoking (16%), and daily intake of salty and pickled foods (87%) were present. On upper endoscopy, 18% of the participants were found to have “moderate to severe H. pylori associated chronic active gastritis." Other endoscopic findings were mild gastritis (61%), severe erosive gastritis (4%), polyps (4%), and metaplasia (21%). Only 4 patients had normal mucosal pathology. Gastric dysplasia or cancer has not yet been identified. Conclusions: Korean Americans have high rates of modifiable risk factors for developing gastric cancer. Novel population-specific gastric cancer prevention and early detection strategies should be designed to eliminate gastric cancer from the Korean American Community.
