Abstract: China has the largest group of patients with colorectal cancer in the world, however, there are few international guidelines for the diagnosis and treatment of colorectal cancer from China, or research of highlevel evidence in China. In recent years, colorectal surgery has developed rapidly in China,and great progress has been made both in clinical practice and in clinical research. But there are still many imbalances and under-regulations. In 2018, Chinese Society of Colorectal Surgery led the establishment of Chinese Colorectal Cancer Surgery Database (CCCD). The retrospective and prospective data collection coming from CCCD showed that the standardization of colorectal cancer surgery and data management needed to be improved, and the awareness of clinical research needed to be further improved. Therefore, how to carry out good clinical research and obtain high-level evidence based upon CCCD will be the great challenge for colorectal surgery in China.
