To compare survival rates in Japan with those in the USA and European countries, we abstracted the 5-year relative survival rate from several data sources. The survival rates of cancer diagnosed in 1995–99 in the USA were abstracted from the Surveillance Epidemiology and End Results (SEER) data from 18 cancer registries (1). The survival rates of cancer diagnosed in 1995–99 in the UK and Norway were from four cancer registries (Norway, the UK: Northern Ireland, Scotland and Wales) in the European Network of Cancer Registries data (2), and the rate of cancer diagnosed in 2000–02 in Japan was reported from six cancer registries (Miyagi, Yamagata, Niigata, Fukui, Osaka and Nagasaki) in the Monitoring of Cancer Incidence in Japan (MCIJ) project (3). Here we compared the survival rate of ovarian cancer coded as C56 (ICD10). Figure 1 shows the 5-year relative survival rate of ovarian cancer by age category.

In all countries, the 5-year relative survival rates of the age group 15–44 years were higher than those of the other age groups and decreased with age.
