In order to make a comparison of recent cancer incidence rates between Japan and other countries, we abstracted the age-standardized incidence rates (ASRs) by 3 age categories (0–59, 60–74 and 75+) from the Cancer Incidence in Five Continents Vol. XI (CI5) (1). International Agency for Research on Cancer provides the CI5 databases on the incidence of cancer recorded by cancer registries (regional and national) worldwide. We used ASRs from the following cancer registries, the United States of America, Beijing in China, Mumbai in India, Hiroshima and Osaka in Japan, the Republic Korea, Gironde in France, Hamburg in Germany, the United Kingdom and Australia from the CI5-XI database. Year at cancer diagnosis were from 2008 to 2012. Figure 1 shows the ASRs for cervical uteri cancer coded as C53 (ICD10). Selected countries comparison showed the ASRs for population aged 60 and older were higher in India (Mumbai) and Republic of Korea than Europe countries, United States, Australia, China and Japan.

In Europe countries, United States and Australia, the ASRs for over 60 years old were higher than the ASRs for same group in Asian countries and India. In almost selected country, proportion of the ASRs over 75 years old were less than the proportion of the ASRs 60 to 74 years old. Figure 2.

View largeDownload slide Age-standardized Incidence rates in uterine corpus cancer (per 100,000). In United States, in the European countries and in Australia, cervical cancer incidence was much lower than that of uterine corps cancer. China and Japan denoted the same tendencies, though the difference between the two primary sites was small. In contrast, in India and in Korea, incidence of cervical cancer was higher. Comparison of the ASR for cervical cancer under 60 years old among the observed countries showed that the ASR was the highest in Japanese registries. Between 60 and 74 years old, India showed the highest ASR, 42.0/100,000 and Republic of Korea followed (28.0). All the other countries showed the incidence of below 20/100,000. For 75 years old and above, India and Republic of Korea were the two countries with high incidence. The ASR in China was the lowest in all the three age groups. As for uterine corpus cancer, there was no clear difference of ASR below 60 years old. The ASR ranged from 2 to 9/100,000. In the age group of 60–74 years, United States showed the highest ASR, 94.5/100,000 and UK and Australia followed. In the Asian countries, China, India, Japan and Korea, the ASRs were less than one third of that of United States. The ASR in United States was still highest in the age group of 75 years and above. The European countries and Australia showed high ASR as well around 70/100,000.
