Burden of Cancer Incidence Below the Age of 40 in Asia 2002 Extrapolated from the Cancer Incidence in Five Continents Vol. IX

In order to compare the burden of cancer incidence below the age of 40 in Asia, we abstracted the crude incidence rate in 2002 from the Cancer Incidence in Five Continents Vol. IX (CI5 IX). The CI5 databases provide access to detailed information on the incidence of cancer recorded by cancer registries (regional and national) worldwide. We used the crude incidence rate by cancer site in 2002 in Japan, China, the Philippines, Thailand, Singapore and India from the CI5plus database, which contains annual incidence for selected cancer registries published in CI5 for the longest possible period. Three registries (Miyagi, Osaka and Yamagata), two registries (Hong Kong and Shanghai), one registry (Manila), one registry (Chiang Mai), two registries (Chinese and Malay) and two registries (Chennai and Mumbai) represent the respective cancer incidence in Japan, China, the Philippines, Thailand, Singapore and India. We selected five cancer sites with the highest incidence rate in each country and compared the difference between the sites and the distribution of cancer burden.
