| [ Summary ] | The number of individuals with colorectal cancer has been steadily increasing in Japan ; currently, more than 50,000 individuals die yearly. Meanwhile, in the United States, the colorectal cancer mortality rate continues to be reduced by conducing a colorectal cancer screening program incorporating fecal occult blood tests, flexible sigmoidoscopy, and total colonoscopy (TCS). In Japan, population‒based colorectal cancer screening using immunochemical fecal occult blood test has been conducted since 1992 ; however, it is strongly anticipated that a new screening program incorporating TCS will be developed. Considering the number of board certified gastrointestinal endoscopists by prefecture and the standardized mortality ratio (SMR) of colorectal cancer, it has been demonstrated that the SMR of colorectal cancer is low in prefectures with many certified endoscopists and tends to be higher in prefectures with few certified endoscopists. However, it remains necessary to discuss how to efficiently incorporate TCS into population‒based colorectal cancer screening programs. | |
