[Present day radiation diagnosis of upper stomach neoplasms].

The paper analyzes over 3000 diagnosed gastric carcinomas. In the author's opinion, a drastic rise in the incidence of carcinomas of the upper stomach (as high as 60-65%) and the change in its anatomy common to gastric cancer--predominance of diffuse (endophytic) forms require a substantial correction of the present approaches to its detection. The paper gives the main points of radiation diagnosis (classic X-ray study, double contrasting, CT) for endophytic carcinomas at this site. In the author's opinion, nearly, as a rule, endoscopically diagnosed carcinomas of the lower esophagus and frequently involvement of the midesophagus are intramural carcinomas of the upper stomach with infiltration swiftly affecting the esophagus. The author considers radiation therapy to become a main method for detection of upper gastric carcinoma. He thinks that the active use of radiation techniques will also substantially expand diagnostic possibilities in these gastric carcinomas and will choose the most optimum plan of their surgical treatment.
