We summarized descriptive epidemiology of prostate cancer in Japan and compared it with that in Western countries. In Japan, the mortality and incidence rates have been increasing particularly in the elderly. The age-adjusted mortality rate (per 100,000 population) rose from 0.5 in 1950 to 8.6 in 2000 and so did the age-adjusted incidence rate from 7.1 in 1975 to 19.9 in 1998 (rates were adjusted to the 1985 Japanese Model Population). In 1993 to 1997, the age-adjusted mortality rate in Japan was about one fifth to half of those in Western countries. Although PSA(prostate-specific antigen) screening may have apparently elevated the incidence rate in the US and some European countries, we did not find such a screening effect in Japan.
我们总结了日本前列腺癌的描述性流行病学情况，并将其与西方国家进行了比较。在日本，死亡率和发病率一直在上升，尤其是在老年人中。年龄调整后的死亡率（每10万人）从1950年的0.5上升到2000年的8.6，年龄调整后的发病率也从1975年的7.1上升到1998年的19.9（发病率根据1985年日本标准人口进行了调整）。在1993年至1997年期间，日本年龄调整后的死亡率约为西方国家的五分之一至一半。尽管前列腺特异性抗原（PSA）筛查可能明显提高了美国和一些欧洲国家的发病率，但我们在日本未发现这种筛查效果。
