[The clinical significance of the histological classification of stomach cancer after Laurén]. / Klinicheskoe znachenie gistologicheskoi klassifikatsii raka zheludka po Laurén.

Clinical parameters were evaluated in 179 operated cases of gastric cancer. They proved significantly different for intestinal, diffuse and undifferentiated tumors according to Laurén. Patients with undifferentiated cancer of the stomach had the worst prognosis; they more often presented with stage IV disease and tumors larger than 6 cm. Three-year survival rate for that histology was significantly lower (26%) as compared to that for intestinal (51%) and diffuse types (40%).

[Helicobacter pylori and chronic gastritis in the gastric biopsy material in a group of randomly selected adult inhabitants of Estonia]. / Helicobacter pylori i khronicheskii gastrit v gastrobiopsiinom materiale v gruppe sluchainoi vyborki vzroslykh zhitelei Estonii.

The occurrence of Helicobacter pylori (HP) was examined in 227 subjects randomly selected among the Estonian population of town Kuressaare. HP was present in 166 subjects (73%). In cases of normal mucosa both in antrum and body HP was lacking. If normal gastric body mucosa was associated with antral gastritis HP was found in both regions. More often the contamination of antral and body mucosa with HP occurred in case of superficial gastritis. In subjects with atrophic gastritis the occurrence of HP decreased. The frequency of HP was high (58%) already in the age group of 15-19 years and increased to 83% at the age of 20-29 years. In subjects over 60 years it decreased due to the development of atrophic gastritis.
