自1960年以来，日本在全国范围内进行了大规模的胃癌筛查。1985年全国体检总人数5161876人，检出胃癌6240例（0.12%）。这些病例中大约有一半是早期癌症。根据日本宫城县的大量胃筛查研究，间接x线法筛查试验的敏感性为82.4%，特异性为77.2%。阳性预测值为1.78%。最近，日本胃癌的死亡率一直在下降。许多研究都在探讨胃癌死亡率的下降趋势与大规模胃筛查的有效性之间的关系。从这些研究以及发病率和死亡率的时间趋势分析、病例对照研究、非实验队列研究等来看，我们认为大规模胃癌筛查对降低该部位癌症死亡率是有效的。
Mass screening for gastric cancer in Japan has been conducted nationwide since 1960. The total number of examinees in 1985 amounted to 5,161,876 and 6,240 cases (0.12%) of gastric cancer were detected. Approximately half of these cases were early stage cancers. According to the studies of mass gastric screening in the Miyagi Prefecture, Japan, the sensitivity of the screening test by the indirect x‐ray method was 82.4%, and the specificity was 77.2%. The positive predictive value was 1.78%. Recently, mortality from gastric cancer has been decreasing in Japan. Many studies have been carried out to investigate the relationship between the decreasing trend of mortality from cancer of the stomach and the effectiveness of mass gastric screening. From these studies and from time trend analyses of incidence and death rates, case‐control studies, nonexperimental cohort studies, etc., it is believed that mass screening for gastric cancer is effective in reducing the death rate from cancer at this site.
