[Establishment of databases of gastrointestinal cancer based on a comprehensive model]

China has a huge population and the number of patients with gastrointestinal cancer is extremely large. With the development of cancer research, the importance of clinical oncology database has been paid more and more attention. It has been 20 years since the Gastrointestinal Surgery Center of the First Affiliated Hospital of Sun Yat-sen University established the database of gastrointestinal cancer from 1994. In this paper, we summarized the composition, daily operation and the experience of construction of database based on multiple-position in one model in our center. We are expecting more units to spontaneously establish relevant databases and gradually move towards data sharing and thus promote the development of gastrointestinal surgery in China.
