title: Intestinal metaplasia with colonic-type sulphomucins in the gastric mucosa; its association with gastric carcinoma.
abstract: The occurrence of intestinal metaplasia with colonic-type sulphomucins: (abbreviated: s-IM or s-positive IM) in the gastric mucosa was studied in 125 patients with gastric carcinoma (GCA), 62 patients with pernicious anemia (PA), 301 and 183 first-degree relatives of GCA and PA patients, 406 outpatients and in 358 controls matched from a large population sample. The sulphomucins (s-mucins) were demonstrated histochemically in endoscopic biopsy specimens by using high iron diamine and Alcian blue (pH 1) methods. The prevalence of s-IM, especially the strongly s-positive IM, was significantly higher in GCA patients than in other series or controls of the same age group. Further, s-IM was significantly more common in PA patients and its prevalence higher in GCA relatives and outpatients than in other series or controls. The occurrence of s-IM was also age-dependent and dependent on the extent of IM. It was suggested that the occurrence of s-IM can be used as a sign of lesions that are more closely associated with GCA than IM is in general.
