We studied the cases of gastric cancer which were found out in the Hitachi Shipyard Medical Center during the survey for 18 years. 21 cases of gastric cancer were observed in total. Among the 21 cases, 14 cases (66.7%) were found out through mass gastric survey, 5 cases (23.8%) in the outpatient clinic and 2 cases (9.5%) were referred from other clinics. Of these 21 cases, the number of early gastric cancer patient and advanced gastric cancer patient, and leiomyosarcoma were 11 cases (52.4%), 9 cases (42.9%), and 1 case (5.7%) resrectively. From our observations curable gastric cancer may be defined as early gastric cancer whose cancer cell invasion is limited to the mucosa and submucosa, and pm (proper muscle) gastric cancer whose cancer cell invasion is limited to the pm with the surviving period of 5 years or more after operation respectively. Our cases of curable cancer were 15 of the 21 cases (71.4%). This good result of curability after operation is attributed to mass gastric survey and annual birthday check up of the workers through close cooperation between the company, workers and health control medical center.
