ABSTRACT
Since the China Gastrointestinal Cancer Surgery Union was established, it has continuously collected the annual reports of 95 gastrointestinal surgery centers nationwide from 2014 to 2017, and collected data on more than 130 000 cases of gastric cancer. This article combines the experience of associated databases at home and abroad to analyze the construction of the China Gastrointestinal Cancer Surgery Union Database, and explore the role of multi-center cooperation and big data analysis in the promotion of gastrointestinal surgery. For a complete database to successfully achieve its ultimate goal, it needs clear goals, continuous funding, a qualified management team, consensus on data content, a high completion rate, and the support and cooperation of an advanced processing system. As a high-quality database with clear construction goals and database project construction based on the goals, while promoting the level of clinical diagnosis and treatment, it is also widely used in risk prediction model development, audit supervision, epidemiological research, health service research, and clinical hypothesis testing, etc. How to build a high-quality database to give a full promotion in clinical diagnosis and treatment is a huge challenge. Although the construction of medical databases in China has just started, we believe that with the further improvement in understanding, management and analysis capabilities for surgical databases, more databases including the China Gastrointestinal Cancer Surgery Union Database will make greater contributions in promoting the development of diagnosis and treatment of gastrointestinal cancer in China and the world.
ABSTRACT
Gastric cancer is one of the most common cancersin China. The proportion of early gastric cancer(EGC) is stillrelatively low in China. The data of China Gastrointestinal Can-cer Surgery Union from 2014 to 2017 can reflect the currentstatus and trends of diagnose and treatment of EGC in China.The union collected data of 134,111 cases of gastric cancer in95 centers in China. The trend analysis was performed with da-ta from centers with at least 3 years data collected. Within allthe patients, the proportion of EGC was 19.7%. The propor-tions of EGC were higher in Zhejiang, Beijing, Jiangsu, Tian-jin, and Shanghai, and were lower in Qinghai, Hainan, InnerMongolia, Yunnan, and Guangxi. The proportion of EGC in-creased from 19.7% in 2014 to 20.9% in 2017. In terms oftreatment, the proportions of endoscopic treatment, laparoscop-ic surgery, and open surgery were 24.3%, 37.7%, and 38.0%.From 2014 to 2017, the proportions of endoscopic treatmentand laparoscopic surgery increased while the proportion ofopen surgery decreased. Among patients received surgery,5.9% of pT1 a patients and 19.6% of pT1 b patients were withlymph node metastasis. In conclusion, the proportion of EGCincreased slightly in China but was still lower than that of Ja-pan and South Korea. Minimally invasive treatment graduallybecome the main treatment method of EGC.
