ABSTRACT

Objective:To explore the clinical significance of standardized screening for diagnosis and treatment of early gastric cancer in Qinghai Province.Methods:Opportunistic early gastric cancer screening was conducted in outpatients of Digestive Department, Physical Examination Center and inpatients of Qinghai Provincial People′s Hospital from January 2016 to December 2020, according to the optimal cut-off values of serum pepsinogen (PG)Ⅰ, PGⅠ/PGⅡ ratio (PGR) and serum gastrin 17 (G17) obtained from the previous screening study of gastric cancer and precancerous diseases in different areas of Qinghai Province. At the same time, the standardized early gastric cancer screening program was applied in 10 municipal (county-level) hospitals in Qinghai Province. The detection rate, early diagnosis rate and endoscopic treatment rate of early gastric cancer in Qinghai Provincial People′s Hospital and the above 10 hospitals in the past five years were analyzed respectively.Results:In the five years, the total detection rate, early diagnosis rate and endoscopic treatment rate of early gastric cancer in Qinghai Provincial People′s Hospital were 0.214% (407/190 178), 17.54% (407/2 321) and 81.82% (333/407), respectively. The above indices in 10 other hospitals were 0.085% (264/309 217), 12.94% (264/2 040) and 37.12% (98/264), respectively. The overall detection rate of early gastric cancer was higher than 0.024% reported previously.Conclusion:The standardized early gastric cancer screening program can not only improve the diagnosis rate of early gastric cancer in Qinghai Province, but also save medical resources. It is an economical, efficient and feasible program, suitable for the highin-cidence area of gastric cancer in Qinghai Province.
