Abstract
The results of gastric mass survey in the employee using serum pepsinogen test from 1998 to 2000 fiscal year were examined. In 7557 employee, 941 were positive for pepsinogen test and 6616 negative. The endoscopic examinations were performed in 728 out of the 941 cases. On these occasions, 13 gastric cancer cases were detected. Afterwards during 3 to 6 years, the other 7544 (7557-13) were examined mainly in indirect gastro-fluororadiography. As a result, 7 gastric cancers were detected out of 928 (941-13) positive for pepsinogen test cases and 20 out of 6616 negative. Finally, 20 gastric cancers were detected out of positive as many as negative for pepsinogen test cases. The people who were positive for pepsinogen test were in the higher rate of discovery of gastric cancer than the people who were negative, but in the same number as these.
In conclusion, the study of the combination of serum pepsinogen test and indirect gastrofluororadiography is absolutely indispensable in gastric mass survey.
