Five-year relative survival rate of larynx cancer in the USA, Europe and Japan.

In order 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. Survival rates of cancer diagnosed in 1995–99 in the USA were abstracted from 18 cancer registries in the Surveillance Epidemiology and End Results (SEER) data (1). Survival rates of cancer diagnosed in 1995–99 in the UK and Norway were from four cancer registries (Norway, the UK: Northern Ireland, the UK: Scotland and the UK: Wales) in the European Network of Cancer Registries (ENCR) data (2), and the rate of cancer diagnosed in 2000–2002 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 cancer survival rate for larynx coded as C32 (ICD10). Figure 1 shows the 5-year relative survival rate of larynx cancer by age category for males; Fig. 2 shows these data for females. In these figures, even if the 5-year relative survival rate was over 100%, the rate was shown as it was.
