胃癌死亡率:1984年日本胃癌死亡人数为49,785人(男30,876人,女18,909人),占癌病人总死亡人数的27.3%(男28.8%,女25.2%),其10万人口死亡率为41.7(男52.5,女31.1)。1935～1984年胃癌死亡率动态曲线表明,在二次世界大战结束前,死亡人数及死亡率基本稳定,战后呈上升趋势,可能是预期寿命的延长和人口老龄化的反映。年龄调整死亡率在1960年达高峰,此后男女两性均呈下降趋势;粗死亡率在1970年后也呈下降趋
Gastric cancer mortality: In 1984, the number of deaths from gastric cancer in Japan was 49,785 (30,876 men and 18,909 women), accounting for 27.3% of the total deaths of cancer patients (28.8% of men and 25.2% of women), and the mortality rate of 100,000 people was 41.7. (Male 52.5, Female 31.1). The dynamic curve of the mortality rate of gastric cancer from 1935 to 1984 shows that before the end of World War II, the death toll and death rate were basically stable, and it showed an upward trend after the war, which may be a reflection of the extension of life expectancy and the aging of the population. The age-adjusted death rate peaked in 1960, after which both men and women showed a downward trend; the crude death rate also declined after 1970.
