[Purpose]To analyze the cost-effectiveness of endoscopic screening for upper gastroin-testinal cancer in Yangcheng County of Shanxi Province.[Methods]People aged from 40 to 69 who participated in upper gastrointestinal cancer screening in Yangcheng County in 2018 were se-lected as the study subjects to participate in upper gastrointestinal cancer screening in 2018,and endoscopic examination with iodine staining and indicative biopsy were performed for screening.The detection rates of precancerous lesions and upper gastrointestinal malignancies,and early di-agnosis rates were calculated,and compared among different groups.The data of screening cost were collected;and the per capita screening cost,the average cost of early case detection and ear-ly detection cost index(EDCI)were calculated.[Results]Among 2 950 subjects undergoing en-doscopy,pathological biopsy was completed in 2 073 cases(70.27％),374 cases of precancerous le-sions(12.68％)and 52 cases of malignancies(1.76％)were detected,among which 17 cases were up-per gastrointestinal cancer with a detection rate of 0.58％,there were 44 early cases with an early diagnosis rate of 84.62％.The detection rate of precancerous lesions and positive cases in men was higher than that of women,but the early diagnosis rate of upper gastrointestinal cancer was lower than that of women;the detection rate of positive cases and digestive tract cancer of 50 years and above were higher than those of people aged 40 to 49.The cost of screening for one positive lesion was 25 528.85 CNY,the cost of screening for one early case was 30 170.46 CNY.The EDCI was 0.52,indicating a good cost-effective value.[Conclusion]The study shows that the early diagnosis and early treatment screening program of upper gastrointestinal cancer has achieved remarkable re-sults in Yangcheng County.The follow-up screening work should focus on men and people over 50 years old,and strengthen the publicity of upper gastrointestinal screening for cancer.
