On January 31, 2015, the “China Early Gastric Carcinoma Screening Program” International Symposium, organized by the Chinese Society of Gastrointestinal Endoscopy, was successfully held in Shanghai. The symposium was chaired by Professor Zhaoshen Li, Executive Director of the Chinese Medical Association, Chairman of the Chinese Society of Digestive Endoscopy, and Director of Gastroenterology Dept. at Changhai Hospital of Shanghai. Experts and guests who attended the meeting included Professor Di Mario, Chief Doctor of Gastroenterology at Parma University in Italy, Secretary-General of the Italian Society of Digestive Endoscopy; Professor Pentti Sipponen of Finland, Chief Designer of the Sydney System Gastritis Taxonomy; Professor Yuan Yuan, Director of the Etiology and Screening Research Department of the Institute of Cancer Research from the First Affiliated Hospital of China Medical; Director Jianming Xu, Department of Gastroenterology of First Affiliated Hospital of Anhui Medical University; Professor Zhuping Fan, Director of Shanghai Renji Hospital’s Physical Examination Center; Professor Zhanju Liu, Director of Gastroenterology of Shanghai Tenth People’s Hospital; Yingcai Ma, Director of Gastroenterology Dept. at Qinghai Provincial People’s Hospital; and other well-known experts in gastroenterology at home and abroad.

Professor Pentti Sipponen first gave a report on “Physiological and Pathological Mechanisms of G-17”; Professor Di Mario gave a report on “Clinical Value of G-17 Detection”; Dr. Jun Zhao made a report on “G-17 Combined with PG Application in Early Gastric Carcinoma Screening”; Director Yalei Wang from the First Affiliated Hospital of Anhui Medical University made a report on “Relationship between PPI and G-17”; Professor Yiqi Du from the Gastroenterology Department of Changhai Hospital of Shanghai made a report on “Relationship between G-17 and Gastric Carcinoma”. Finally, under the auspices of Professor Zhaoshen Li, the participating experts discussed the significance of G-17 combined with PG in the screening of early gastric carcinoma and the clinical boundary values. Based on the domestic and foreign literature, the serological boundary value of gastroscopy was initially formed: PG I≤70ug/L and PGI/PG II≤7.0, and G-17≤1pmol/L or G-17≥15pmol/L. In the next step, it is planned to further clarify the screening value of this program for early gastric carcinoma through a multi-center clinical evaluation study, and finally develop an early gastric carcinoma screening process in line with China’s national conditions and the epidemiological characteristics of gastric carcinoma. The content of the symposium was widely recognized by the participants, and the symposium made a complete success.
