BACKGROUND: The aim of this study is to examine differences in colorectal cancer incidence estimates of GLOBOCAN 2012 and observed colorectal cancer incidence rates in 19 selected countries.   .
 
METHODS: Estimates of colorectal cancer incidence for 19 countries were gathered from GLOBOCAN 2012. Colorectal cancer incidence was retrieved from published data from 2008 to 2012. Observed colorectal cancer incidence rates were compared with colorectal cancer incidence estimates of GLOBOCAN 2012. Incidence rates were standardized using World standard population.
 
RESULTS: When observed colorectal cancer incidence rates of 2012 or nearest year to 2012 were compared with estimates of GLOBOCAN 2012, Slovenia, Australia, Japan, New Zealand, U.S.A showed 5% or higher incidence than estimates of GLOBOCAN 2012 in men. Especially, those of Australia, Japan, and New Zealand were 10% or higher than estimates of GLOBOCAN 2012. Korea, Denmark, Spain, Israel, Canada showed 5% or lower incidence than estimates of GLOBOCAN 2012 and among these countries, incidence rates of Korea and Israel were at 10% or lower than estimates of GLOBOCAN 2012. In women, New Zealand, Australia, Czech, Japan, U.S.A showed 5% or higher incidence than estimates of GLOBOCAN 2012 and among these countries, and incidence rates of New Zealand, Australia, Japan, U.S.A were 10% or higher than estimates of GLOBOCAN 2012. Korea, Denmark, Croatia, Israel, Italy, showed 5% or lower incidence than estimates of GLOBOCAN 2012 and among these countries, incidence rates of Korea and Israel were 10% or lower than estimates of GLOBOCAN 2012.
 
CONCLUSION: In this study, there was considerable difference in colorectal cancer incidence estimates of GLOBOCAN 2012 and observed colorectal cancer incidence rates. GLOBOCAN is important in setting global health priorities, but also consider limitation of the estimates.
