Abstract:
This paper presents 231 cases of carcinoma in the region of the gastric cardia.In 96 of the cases-gastrectomy specimens were obtained,and for the remaining cases biopsy specimens were taken through gastroscopy.The study of cancerous cells in their developing stages in the tissues taken from the neighborhood of the tumours revealed that there were 4 types of histogenesis of gastric-cardia carcinoma:1.cancerous degeneration of cells at the glandular necks in the gastric foveolae;2.cancerous degeneration of a single cell or a few cells of the glandular epithelium;3.dysplasia of the epithelium with-malignant change;4.intestinal metaplasia of the epithelium with cancerous change.It is suggested that dysplasia of the epithelium and intestinal metaplasia of the epithelium accompanied by dysplasia are significant precancerous changes.
