Radiation of the stomach was not absolutely performed in neoadjuvant and adjuvant regimes. The main indications to therapy were cancer of the cardiac portion of the stomach with patency disturbances and pain syndrome.Effect of palliative treatment was achieved in 60 % of cases. Absence of modern planning systems inhibitsadministration of the stomach cancer radiation therapy. Groups of patients with evident indications to radiation therapy of the gastric cancer were identified. When planning therapy it is advisable to use well-known data with the landmarks regionto bone formations in epigastric region.The purpose of this work is to estimate efficiency and indications to radiation therapy of the stomach cancer in two periods – 1997-2003 and 2016-2017 years; to detect tendencies in radiation therapy indications on the basis of the previous experience and present state of surgery.Material and methods.
