A population-based screening for detection of early cancers evaluated the prevalence of precancerous gastric lesions in an area in Shandong Province, China, with one of the world's highest rates of stomach cancer.
A total of 3433 residents aged 35 to 64 yr received gastroscopical examinations with biopsies taken from standard locations.
Chronic atrophic gastritis was nearly universal; less than 2% of the population had biopsies showing entirely normal mucosa or only superficial gastritis.
Intestinal metaplasia was the most advanced lesion for 33% and gastric dysplasia for 20%, although the prevalence of each increased significantly with age.
