Abstract

Objective: Detection rate is one of the criteria used to evaluate the quality of gastric cancer screening programs that use esophagogastroduodenoscopy. However, the detection rate is biased by the age distribution and sex ratio of the population undergoing endoscopy. Therefore, we assessed the quality of our screening program using a standardized detection ratio adjusted for age and sex. <br>Methods: Between January 4 and December 28, 2016, 4,927 persons who underwent a health check-up including ultra-slim endoscopy at our clinic, MedCity21, were enrolled in this study. We determined standardized detection ratios and gastric cancer detection rates.<br>Results: Gastric cancer was detected in 13 male subjects and the value of the standardized detection ratio was 3.74. In contrast, gastric cancer was only detected in one female subject and the value of the standardized detection ratio was 0.89. Among all subjects, the value of the standardized detection ratio was 3.04 and the gastric cancer detection rate was 0.28%.<br>Conclusions: Gastric cancer was detected successfully in our health check-ups based on assessment using the standardized detection ratio.
