Age-specific incidence rates of gallbladder cancer in the world

In order to make a comparison of the age-specific cancer incidence rate of gallbladder and other parts of biliary tract (hereinafter, referred to as gallbladder cancer) between Japan and other countries, we abstracted cancer incidence rate from the Cancer Incidence in Five Continents Vol. XI (CI5) (1). The 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 cancer incidence rate in five countries in Asia (China, India, Japan, Republic of Korea and Thailand), three countries in America (USA, Canada and Brazil), two countries in Oceania (Australia and New Zealand) and four countries in Europe (UK, France, Germany and Italy). Some countries have plural cancer registries and we aggregated all the registries to calculate the incidence rate in the countries from the CI5-XI database. The period of years at cancer diagnosis were from 2008 to 2012. Gallbladder cancer was coded as C23 –C24 based on International Classification of Diseases 10th Revision.
