title: [Controlled clinical studies for topographic analysis of atrophic gastritis and stomach cancer].
abstract: The purpose of this cross-sectional study was to assess the relation between intestinal and diffuse stomach cancer at its various locations with topography of atrophic gastritis. The study population consisted of 3435 patients who reported over the period of 1991-94 for the first time to gastroenterological outpatient clinics of 7 university medical centers in Poland. Among these subjects there were 131 histologically proved consecutive cases of gastric carcinoma. The reference group consisted of 1540 patients among whom endoscopic examination did not reveal peptic ulcers, polyps, deformations of antrum or bulbus duodenum and mucosa erosions. Among the gastric cancer cases there was a higher prevalence of atrophic gastritis in the intestinal than in the diffuse type. The highest prevalence of atrophic gastritis irrespective of its degree and stomach area was observed in the tumour-area of intestinal cancer located distally (78.9%), and the lowest in the tumour-free area in diffuse proximal cancer (18.5%). Prevalence of atrophic pangastritis (atrophic gastritis present both in the corpus and antrum) was also highest in intestinal distal cancer (69.2%) and lowest in diffuse proximal cancer (21.7%). For other types of cancer the prevalence rates of atrophic pangastritis was 50.0% in intestinal proximal cancer and 37.5% in diffuse distal carcinoma. The age-adjusted correlation coefficients between gastritis score in the tumour-area and tumour-free area were highly significant. It was shown that only atrophic pangastritis was significantly associated with gastric cancer irrespective of its histology and location (OR = 3.8, 95% CI:2.4-6.0), however, it was much stronger related to the intestinal gastric cancer panga (OR = 5.9, 95% CI: 3.1-11.0), than to the diffuse carcinoma (OR = 2.2, 95% CI: 1.1-4.3).
