To investigate changes in the results of treatment of gastric carcinoma, two 10-year periods between 1963 and 1982 with 641 and 630 patients, respectively, were compared. In the two groups, 94 percent and 92 percent of patients were operated on. The operation was considered curative in 200 and 265 patients in Groups 1 and 2, respectively. There was a shift towards more radical operations, with 215 total or subtotal gastrectomies in Group 2 compared with 76 in Group 1, when distal gastric resection was considered radical enough. Despite the increasing number of curative operations and more radical surgery in Group 2, no progress in the 5-year survival rate was noted. Distal and subtotal gastrectomies gave slightly better results than total gastrectomies, but the most important single factor contributing to the long-term survival was cancerous invasion of the serosa. It is concluded that in the past 20 years, the results of surgical treatment of gastric carcinoma have not improved, despite the more advanced diagnostic methods and more radical surgery.
