The implementation of colorectal cancer screening programs in different countries is different.

Colorectal cancer screening

Researchers collected data on 31 million colorectal cancer patients diagnosed in 21 European countries since 2000 (mostly to 2016), aiming to analyze the age-standardized incidence and stage ratio of colorectal cancer over time.

Incidence of colorectal cancer in different countries

In countries with long-term colonoscopy and stool examination programs (Australia, Czech Republic and Germany), the incidence of colorectal cancer has decreased over time , and the annual average percentage change (AAPC) of men and women fluctuates at -2.

In countries with long-term colonoscopy and stool examination programs (Australia, Czech Republic and Germany), the incidence of colorectal cancer has decreased over time

In the countries that have implemented screening programs during the study period, the age-standardized incidence of colorectal cancer remained stable or showed an upward trend in the year when the screening was implemented.

Proportion of different stages of colorectal cancer in different countries

In countries that are rapidly achieving high screening coverage (Denmark, the Netherlands, and Slovenia), the incidence of age-standardized colorectal cancer first increased and then decreased.

Among countries with long-term screening programs, colorectal cancer mortality rates have the largest decline.

Colorectal cancer screening programs are implemented in different countries, and the incidence and mortality of colorectal cancer are different.
