OBJECTIVE: To analyze the efficacy of endoscopic screening for @entity356 in rural population in high risk areas of upper @entity1820 in Henan province. METHODS: Subjects aged 40-69 years in the high risk areas were selected to participate in the endoscopic screening based on the cluster sampling, and screening-positive subjects were sampled for pathological examination. The data of screening were summarized and the detection rates of severe chronic @entity4726 , severe @entity1944 , @entity3146 , high @entity3146 , early and @entity5 were calculated, and the constituent ratio of early @entity5 cases was calculated. The detection rates and early diagnosis rates for the first round screening and follow-up screening were compared. RESULTS: In the 5 years, a total of 88 263 subjects were endoscopically examined in the first round screening and 4 004 subjects were diagnosed with @entity3146 or above (the detection rate was 4.54%), in which 3 256 cases were with @entity3146 (the detection rate of 3.69%), 366 cases with high @entity3146 (the rate of 0.41%), 199 cases with early @entity5 (the rate of 0.22%) and 183 cases with @entity5 (the rate of 0.21%). The number of cases of high @entity3146 and early @entity5 was 565 and the early diagnosis rate was 75.53%. 1 894 subjects with severe chronic @entity4726 , severe @entity1944 and low grade intraepithelial were followed up with a compliance of 66.32%. A total of 45 cases of early @entity5 were diagnosed, with a detection rate of 2.38% and early diagnosis rate of 100%. The detection rate and early diagnosis rate in the follow-up screening were both statistically significantly higher than that in the first round screening (P<0.01 for both). CONCLUSION: The efficacy of endoscopic screening for @entity356 is significant in high risk areas of upper @entity1820 , and improving the quality of follow-up screening will achieve a better performance of the screening.
