We adjusted the prostate cancer incidence rate in Japan for differences between Japan and the US in the proportion of latent prostate carcinoma identified at autopsy and of localized tumors among all carcinomas of the prostate. The adjusted incidence rate of prostate cancer in Japanese in Japan by this method is estimated to be between 24.9 and 33.3 per 100,000 population, based on incidence rates from the population-based cancer registries of Miyagi, Japan, and Los Angeles and Hawaii, USA. The rate estimated here is almost 3-4 times greater than the rate reported previously. The difference in the incidence rates of prostate cancer between Japanese in Japan and the US (32.2-49.8 per 100,000) may therefore be substantially smaller than previously thought.
我们针对日本与美国在尸检时发现的潜伏性前列腺癌比例以及所有前列腺癌中局限性肿瘤比例方面的差异，对日本的前列腺癌发病率进行了调整。基于日本宫城县、美国洛杉矶和夏威夷以人群为基础的癌症登记处的发病率，用这种方法估算出的日本国内日本人前列腺癌调整发病率为每10万人24.9至33.3例。此处估算的发病率几乎比之前报告的发病率高3至4倍。因此，日本国内的日本人与美国（每10万人32.2至49.8例）前列腺癌发病率的差异可能比之前认为的要小得多。
