Colorectal Cancer Screening: Current Status and Progress / 胃肠病学

ABSTRACT

Colorectal cancer (CRC) is one of the most common malignancies worldwide. In recent years, the overall incidence of CRC in China has shown an upward trend. According to the national estimates of cancer in China, CRC was the second most commonly diagnosed cancer of the digestive system. Screening of CRC can significantly reduce its morbidity and mortality. The screening methods are diverse. At present, a two-step screening program based on fecal immuno-chemical test (FIT) and colonoscopy is recommended by authoritative guidelines or consensus in many countries. Other screening methods can be used as individualized options and supplements. Multigene germline mutation detection should be performed for extremely high-risk population with multiple colorectal polyps (>10 polyps) and CRC personal or family history; or with more than 20 polyps.
