Abstract
Using the histological degree of gastric mucosal atrophy derived from 65 samples of dissected specimens obtained at surgery for gastric cancer as a standard, we examined the capability of indirect X-ray examinations and the pepsinogen assay to diagnose the degree of atrophy. These two methods were equally sensitive in diagnosing pathological and advanced gastric mucosal atrophy, but X-ray examinations were also found to be useful for diagnosing stomachs having little or no atrophy. While the concomitant use of X-ray examinations and a pepsinogen assay has been propounded, it has been indicated that X-ray examinations are useful for diagnosing the degree of atrophy, which would allow it to independently improve the accuracy of screening for gastric cancer.
