Time trends of age-standardized rate (ASR) of prostate cancer incidence (ICD-10: C61) were compared among 13 selected cancer registries and ethnic/racial groups in Asia. Data source was the Cancer Incidence in Five Continents, Vols IV–IX (year at diagnosis: 1973–77, 1978–82, 1983–87, 1988–92, 1993–97 and 1998–2002, respectively). World population was used for age-standardization. Asia was divided into three areas, Eastern Asia, South-Eastern Asia and South-Central and Western Asia. China and Japan were in Eastern Asia, Philippines, Singapore and Thailand were in South-Eastern Asia and India, Israel and Kuwait were in South-Central and Western Asia.

Figure 1 shows time trends of ASR of prostate cancer incidence. Manila (Philippines) and Jews in Israel had higher ASRs than other registries all through the observation period, whereas Shanghai (China), Chiang Mai (Thailand) and Chennai (India) showed comparatively low ASRs. There was an overall increasing trend in all three Asian areas, except in Mumbai (India) where no obvious increase and decrease was observed. In all the registries, except Chiang Mai (Thailand) and the two registries in India and Kuwait, ASRs have been increasing since 1988–92. Above all, Israel demonstrated a peculiar transition; the ASR was originally high ∼15–20 in 100 000 from the beginning of the observation period, and increased suddenly up to two or three times.

Time trends in age-standardized prostate cancer incidence rate (ICD-10: C61) in 13 cancer registries in Asia. Note: Data were downloaded from IARC CANCER Mondial Statistical Information System (http://www-dep.iarc.fr/). Data were tabulated by the authors of this article. Periods of year at diagnosis were representative, and they included the following exceptions: the first period was 1974–77 for Hong Kong (China), 1975 for Shanghai (China) and 1972–76 for Jews (Israel); the second period was 1979–82 for Osaka (Japan), 1982 for Chennai (India), 1977–81 for Jews (Israel) and 1979–82 for Kuwait; the third period was 1982–86 for Jews (Israel); the fourth period was 1988–93 for Kuwait; and the fifth period was 1994–97 for Kuwait. Note that calculated incidence rates were values averaged across 5 years, which could have rounded rapid annual changes (a spike or drop). Responsibility for this presentation and interpretation lies with the authors of this article.
