Description

Fluoroscopic examination has been widely adopted as the primary screening in gastric-mass-survey. More subjects are to be examined and early discovery of cancer and its immediate medical treatments are necessary in order to decrease the death rate of gastric cancer. Under the present circumstances, however, fluoroscopic examination can hardly meet the need for all the cancer ages.<BR>Since 1962, we had adopted the Gunma-Method as the primary screening in which we picked up those who proved positve-over Type V by Shichijo's reaction (a non-specific, biological test of gastric caner), those who complained of their gastric troubles, and those who had hereditary character of the digestive tracts.<BR>This method was very efficient, but it was suspected that this method might fail to detect some gastric cancer. Therefore we have adopted fluoroscopic examination accompained with this method as the primary screening since 1964. Thus we have made a comparative study of the two methods.<BR>We examined 39, 049 cases during 2.8 years from 1964 to 1967<BR>Suppose we made the primary screening of those cases by the Gunma-Method, we would be able to omit 14, 459 cases (37.0%). The fact was that 22 cancer patients were found among those omitted cases. This figure occupied 23.4% of 94 cancer patients who were detected in the primary screening when fluoroscopic examination was used jointly with Shichijo's reaction. when we shifted the screening line from TypeV to Type III and also picked up even those who complained of their gastric troubles “once in a while” at the time of the primary screening, 12, 407 cases (32.2%) were to be omitted. In this case only 8 cancer patients (8.5%) were found among those omitted cases. In this way, the failing number was to be much decreased.<BR>We call this method “new Gunma method” and we believe this new method will be effectively and conveniently used as the primary screening of gastric-mass-survey
