Optimal Endoscopic Screening Interval for Early Detection of Gastric Cancer: a Single-Center Study

Background: The optimal endoscopic screening interval for early gastric cancer (EGC) detection still remains controversial. Thus, we performed this prospective study to clarify the optimal interval between endoscopic examinations for EGC detection. Methods: A questionnaire survey for penultimate endoscopy and gastric cancer (GC) diagnosis interval was used; the findings were then analyzed. The patients were divided into two groups according to GC type and endoscopic examinations intervals. Results: A total of 843 patients were enrolled. The endoscopic GC detection interval (P 2 years and without screening. Similar results were observed in those with < 3-year intervals. Conclusion: Triennial endoscopic screening might be as effective as biennial screening in increasing the detection rate of EGC and the risk of subsequent curable endoscopic resections.
