  • Abstract
  • Look Inside

 1) Around 1950, an investigation of the gastric cancer was developed by research groups and they determined a definition and classification of the early gastric cancer in 1962. And it made our practitioner's purpose clear.

 2) Around 1962, a training how to make a diagnosis of early gastric cancer was started for our practitioner and by the beginning of 1970's, it had spreaded into doctor's associations in each district of Tokyo with a surprising rate.

 In 1979, when we investigated eastern nine districts' and other doctor's associations is Tokyo, it became clear there was synergistic effect between an improvement of quality and quantity of the mass survey and it started to show a result of man power approarch.

 3) From 1960's to the first half of 1970's, the training of the practitioners by research groups enhanced a detection of the early gastric cancer and that offerred new materials to the research groups and we believe that there was so called feed back cycle between them.

 4) It has gradually became a strong trend that our practitioners, who has more contact to the citizens of Tokyo, have been placed in charge of detecting early gastric cancer.

 5) In spite of increased number of detected relatively early gastric cancer (pm type cancer), there is still no decreased number of s type cancer. This seems to be due to a character of testees, less concern to the health and a state of mind which is afraid of discovering cancer in them. Therefore, from now on, our practitioner should aim to promote a campaign for enlightening local residents who have no opportuities to have mass survey such as occupational one.

We believe that such approach is the best way to control the gastric cancer in our country.
