[Incidence and significance of the gastric mucosal constellation in pernicious anemia].

1977 cases with gastric complains but without localized findings like ulcer or cancer were investigated by gastroscopy with biopsies of corpus and antrum ventriculi. We found in 5.5% an isolated mucosal atrophy of the gastric corpus (mean age 67.2 years compared to 59.4 years in cases with normal mucosa). 0.7% showed an atrophic gastritis of the antral mucosa, 0.9% an atrophic gastritis of the body and the antrum. Most of the cases with an isolated atrophy of the gastric body gave findings of hematologic disturbances. In all cases with isolated atrophy of the gastric body, including localized findings in the stomach, we found in 10.8% neoplastic processes, in another 3.9% hyperplasiogenic polyps. It seems to us of clinical importance to evaluate the gastric histology of the antral and body mucosa routinely because of the high incidence of pernicious anemia-like gastric atrophy and its relation to gastric neoplasias.
