[The microspectrophotometric criteria in estimating gastric mucosa dysplasia in non-invasive adenocarcinoma].

Computer analysis was carried out of images of changes in area and ploidy of gastric mucous nuclei associated with concomitant pathology, dysplasia and non-invasive adenocarcinoma of the stomach. In grave dysplasia, the area and ploidy of a nucleus were 213.7 +/- 3.42 microm2 and 10.2 +/- 0.2 c, and in well- or moderately differentiated cell adenocarcinoma--333.8 +/- 16.5 microm2 and 14.95 +/- 1.9 c, respectively. It is suggested that this evidence can contribute to a more accurate estimating of pathological processes taking place in the gastric mucosa when differential diagnosis between dysplasia and stomach cancer is undertaken.
