Key clinical point: A shorter gastric observation time during index esophagogastroduodenoscopy (EGD; preceding gastric cancer diagnosis) serves as an important predictor of the occurrence of interval advanced gastric cancer.
Major finding: A shorter observation time (<3 min; adjusted odds ratio 2.27; 95% CI 1.20-4.30) at preceding endoscopy was independently associated with an increased risk for interval advanced gastric cancer.
Study details: Findings are from a retrospective nested case-control study that included 1257 patients diagnosed with gastric cancer within 6-36 months of “cancer-negative” index EGD, of which 102 patients had advanced gastric cancer.
Disclosures: This study was supported by the Research Fund of the Korean Society of Gastroenterology and a National Research Foundation of Korea grant funded by the Korea government. The authors declared no conflicts of interest.
