[Groups at high risk for stomach cancer morbidity and the effectiveness of dispensary care].

The paper presents the results of the 10-year follow-up of 1,237 patients at high risk for stomach cancer. Among them, 669 patients suffered from chronic gastric ulcer, 78--polyps, 382--chronic gastritis and 108 underwent resection of the stomach more than 10 years ago. Repeated gastroscopic examinations, including biopsy, carried out within the last two years, revealed malignancies in 405 cases (32,7%): chronic ulcers--10.

[Histogenesis of stomach cancer and the role of intestinal metaplasia in the process].

The study of 854 gastrobioptic specimens and 102 stomachs resected in connection with cancer justified the assumption that intestinal metaplasia as such was not of a precancer character but indicated only the presence of a pathological process in the stomach. Malignization started in places of atypical hyperplasia of the epithelium, mostly at the level of the cervical part of the glands and gastric fossae. The investigations conducted showed that under conditions of pathology proliferation of cambial elements could occur by two ways.
