  • Look Inside

 Results of gastric mass survey conducted for five years in the town M and for three years in the town K have been reported.

 1) Gastric cancer has been detected in 18 cases, including four (22.2%) of early cancer (Ⅱc, 1; Ⅱc+Ⅲ, 2; and Ⅰ, 1). Of the remaining 14 cases of advanced gastric cancer, one presented a Ⅱc-simulating finding, three closely resembled type and still another very much like a type. These were all slight in their infiltration, only partly reaching pm. All of 14 operated patients are alive, and except for one, they are all in good health and enjoying normal way of life. The longest survival time is 4 years and 10 months.

 2) Of 18 cases of gastric cancer thus detected 7 had previous experience with gastric mass survey; three did not undergo subsequent thorough check-up in spite of the advice to do so; the remaining 4 had been pronounced as normal one year before.

 3) The number of examinees in both towne has begun to decrease since the second year of survey institution.

 4) The percentage of actually undergone thorough check-up in the first year was 65.7 in the town M and 67.7 in the town K. A far higher percentage, 83.4% in M and 87.8% in K, is now achieved since the initiation of thorough check-up by means of gastrofiberscope done at the place of examination.

 5) In the town of M, where gastric mass survey has been conducted for five years running, the whole number of persons having undergone it was 2,874, and the actual number of examinees was 1,500. Of these, 781 persons have undergone it only once (51.7%); 333 persons, twice (22.0%); 119, three times (13.1%); 130, four times (8.6%); and only 62 persons were examined five times (4.1%).

 6) On the basis of the present study, it has further been commented on consecutive gastric mass survey as it really ought to be.
