  • Abstract
  • Look Inside

 Since 1983, individualized screening systems for stomach cancer have been performed by the Kanazawa Medical Association in order make up for the low rate (2%) of examinees who utelized our mass examination by less. Furthermore, in order to establish the high quality of this screening system, a mass screening committee for stomach cancers has been used by Kanazawa Medical Association since 1992. On utilizing this new system, we employed several methods of educational programs, double check interpretation of x-ray films of the stomach, referee judgment by specialists, and comparison of the current year's x-ray films with those taken the year before. In this paper, we introduced the individualized screening system used by our medical association. The results obtained are as follows.

 1) During the past five years, 162 clinics and hospitals in our medical association had 36,093 examinees, and detected 95 cases of gastric cancer (a rate of 0.26%) with 58 cases of early gastric cancer (a rate of 61.3%).

 2) In this period, the number of examinees in our city rose by 14~15% in this individualized screening system compared to the 4% increase in mass examination by bus.

 3) Despite a lower rate of check up (6%) in the first screening, cancer rates and early cancer rates were not significantly different from previously.

 4) This system contributed to the improvement in the techniques of x-ray photographing and in the ability of film interpretation among our association's doctors. Therefore the rate of participated close examinees was over 90%.

 Our data indicates that our individualized x-ray screening system will be as useful as mass examination using endoscopy.
