A study conducted by researchers at Peking Union Medical College Hospital provides new insights into intestinal neoplasms, specifically colorectal cancer (CRC). The study aimed to assess the trends in participation and detection for advanced colorectal neoplasm under different screening intervals in multi-round fecal immunochemical test (FIT)-based CRC screening. The researchers found that as screening rounds increased, participation rates gradually increased, reaching 78.45% and 74.97% for annual and biennial screening strategies, respectively. However, the incremental benefits in CRC detection diminished over time. The study suggests that tailored strategies, such as extending intervals for individuals with multiple negative FIT results, may optimize effectiveness and cost-efficiency in population-based CRC screening.
