In Japan cancer mortality statistics have been prepared by site, sex, and age group since 1937. The trends in age-adjusted death rates for selected sites from 1937 to 1975 in intervals of two or three years, and the age-adjusted death rates for some sites by prefecture in 1968-1972 were summarized. Concerning the accuracy of cancer mortality statistics, special consideration should be given to senility in Japan. In 1975 deaths due to senility accounted for 4.3% of all deaths for all ages. Though the regional cancer registration was being operated in 16 prefectures in Japan as of 1976, the incidence rates were published for only six prefectures. The percentage of cases registered from death certificate only in six registries in Japan was compared with that in the registries in the United States, indicating that the completeness of registration was yet unsatisfactory in Japan. As an index of accuracy of diagnosis, the percentage of cases confirmed histologically was also compared.
自1937年以来，日本一直按部位、性别和年龄组编制癌症死亡率统计数据。总结了1937年至1975年期间部分部位每两到三年的年龄调整死亡率趋势，以及1968 - 1972年部分部位按县划分的年龄调整死亡率。关于癌症死亡率统计的准确性，在日本应特别考虑衰老因素。1975年，衰老导致的死亡占所有年龄段死亡总数的4.3%。截至1976年，日本有16个县在进行地区癌症登记，但仅公布了6个县的发病率。比较了日本6个登记处仅根据死亡证明登记的病例百分比与美国登记处的情况，结果表明日本登记的完整性仍不尽人意。作为诊断准确性的指标，还比较了组织学确诊病例的百分比。
