During the 9-year period from 1980 to 1988, a-total of 108, 609 people underwent group examinations for early detection of cancer of the stomach. Of this number 197 people (0.18%) were found to have contracted gastric cancer. The detection rate followed an upward curve in step with the increasing use of gastroscopes. Of those who underwent surgery, 140 people survived three years post-operatively. By stage, the survival rate was 95.6%(65 cases out of 68) for stage I, 93.3%(28 of 30) for stage II, 82.6%(19 of 23) for stage III, and 10.5%(2 of 19) for stage IV.
In 1988 alone, 15, 174 people received mass screenings and 45 stomach cancers were detected (0.297%). The detection rate was high, but it is to be noted that of the 48 people, 18 had been found normal in the previous year's check up, and that five cases of the 18 apparently had escaped the notice of physicians. This fact suggests that more careful examination be needed.

Clinical research was carried out on stomach cancer cases treated in the surgery department of our hospital, which provides medical services to the populace in the southern part of Fukushima Prefecture.
During the 10-year period between Jan. 1981 and Dec. 1990, a total of 641 cases were referred to surgery. Of the total, 568 cases or 88.6% were operated on and 501 or 78.2% were radical gastrectomy cases.
When a careful check was made on these cases with respect of staging, histology, invasion degree and lymph node metastasis, it was found that the ratio of early stage stomach cancer cases was increasing steadfastly year after year.
Regarding the 5-year survival rate, 63.7% was scored by the operated cases and 73.2% by radical gastrectomy cases. These rates were up by 18.6% and 17.0% from five years ago. The above findings indicate that improvement in treatment results is due to technical progress in detection of gastric cancer at early stages.

Our examination was performed on 1, 541 men and 3, 803 women. Reviewed were blood pressure, obesity, anemia, fatty tissue (lipide), liver function, urine-suger and protein, urobilinogen, and their abnormalities.
(1) High blood pressure was found in 53.7 % of the men and 68.3 % of the women, with higher rates found in the middle to older age groups of both men and women.
(2) Obesity, by the Minowa method, was found to be over 20 %, with the higher rate being in women. The tendency to obesity in men was found to decrease with age. In females, abnormalities of blood pressure, total cholesterol, triglyceride, thickness of subcutaneous fatty tissue (of the upper arm and shoulder blade areas) were discovered to be greater in proportion to obesity.
(3) Abnormalities in GPT were seen as 15.3 % in men and 7.3 % in women. According to age group in men: Those in their 30's, 21 %, in the 40's, 27.2 %, 50's, 12.7%, 60's, 9.1 %.
A study on the effects of alcholic beverage consumption will be included in the 1983 survey.
