The results of combination therapy of 66 patients with inoperable gastric cancer are presented. The complex of therapeutic measures included: preoperative gammatherapy with a single dose of 350--400 rad and total dosage up to 2400--3000 rad, palliative operations or explorative laparotomy with subsequent postoperative irradiation (up to 4500--6000 rad) or chemotherapy with 5-fluoruracil (up to 3--5 grams). The average survival of patients was 9.3 +/- 0.9 months, and it was dependent on tumor process spread and the kind of surgical intervention. Radiotherapy is shown to effect positively the clinical course of the disease and patient's survival.
