近年来,随着急性白血病治疗效果的提高,尤其是儿童急性淋巴性白血病的治愈病例有所增加。如再用白血病的死亡率摧测发病率则欠妥当。据日本厚生省人口动态统计报告,日本人白血病男女死亡率每年都在增加,1987年男性为5.6/10万,女性为3.7/10万。但从修正死亡率看,1965年以后,男性不足4/10万,女性不足3/10万,呈稳定状态没有增加趋势。这就说明白血病死亡率的增加,主要是由于年龄构成的老龄化所致。与其他国家相比,1986年美国男性为8.1/10万,女性为6.3/10万,英国威尔
In recent years, with the improvement of the therapeutic effect of acute leukemia, especially the cure of childhood acute lymphoblastic leukemia cases have increased. If we use the mortality rate of leukemia to test the incidence is not proper. According to the Ministry of Health, Labor and Welfare’s vital statistics, the death rate of leukemia in men and women in Japan is increasing every year. In 1987, the number of males was 5.6 per 100,000 and that of females was 3.7 per 100,000. However, from the revised mortality rate, after 1965, there were no fewer than 4 to 10 million men and no more than 3 to 10 million women, showing no signs of steady growth. This shows that the increase in the mortality rate of leukemia is mainly caused by the aging of the age composition. Compared with other countries, in 1986 the United States was 8.1 / 10 million males, 6.3 / 100 000 females,
