The number of deaths from colorectal cancer in Japan continues to increase, and the age-adjusted mortality rate has plateaued in recent years. To address this situation, strengthening screening on a national scale is essential. Currently, there are population-based screenings, such as municipal and workplace screenings, in Japan, as well as opportunistic screenings like health check-ups, which makes comprehensive management of cancer screening data challenging. Therefore, discussions must continue to build a system that enables the creation of a screening database and its integration with the National Cancer Registry. Regarding population-based colorectal cancer screening, even if the ongoing randomized controlled trials on colonoscopy (CS) show a reduction in mortality rates, considering the capacity and adherence to CS, it seems reasonable to continue screening based on the fecal immunochemical test (FIT) while incorporating CS for specific age groups, such as those in their 50s. Taking into account medical economics and resources, we need to discuss the target age and frequency of CS screening, practitioner requirements, and methods for data collection and management. This presentation outlines the current status and challenges of colorectal cancer screening in Japan, as well as the expectations and future outlook for incorporating CS into organized screening programs. |
