Abstract:
Objective:To analyze the effects of esophageal cancer screening in Henan rural areas with cancer screening program from 2014 to 2018.Methods:From July 2014 to June 2019, according to the National Early Diagnosis and Treatment of Upper Gastrointestinal Cancer in Rural Areas Project, cluster sampling method was adopted in 16 counties/county-level cities in rural areas with high incidence of esophageal cancer in Henan province. Endoscopic iodine staining and indicative biopsy were used to screen esophageal cancer. The patients with mild and moderate dysplasia confirmed in screening were followed up. The distribution of esophageal diseases in the screening population was calculated, and Chi-square test was used to compare the differences of detection rate and early diagnosis rate between the primary screening population and the follow-up population.Results:The age of 116 630 primary screening population was (54.29±7.70) years old, and the proportion of males was 41.2% (48 108). In the primary screening population, patients with normal esophagus, mild to moderate dysplasia, severe dysplasia and above accounted for 92.91% (108 363), 6.03% (7 035) and 1.06% (1 232), respectively. The detection rate of esophageal cancer was 1.06% (1 232/116 630), and the rate of early diagnosis was 85.80% (1 057). Among the follow-up population of 6 154 people, those with normal esophagus, mild to moderate dysplasia, severe dysplasia and above diseases accounted for 63.45% (3 905), 33.13% (1 519) and 3.41% (210), respectively. The detection rate of esophageal cancer was 3.41% (210/6 154), and the rate of early diagnosis was 91.90% (1 939). Compared with the primary screening population, the risk of esophageal cancer was higher in the overall follow-up population, people either with mild or with moderate dysplasia diagnosed in primary screening, with OR values (95 %CI) of 3.23 (2.78, 3.75), 1.85 (1.49, 2.29) and 8.13 (6.69, 9.88), respectively. Conclusion:From 2014 to 2018, in the early diagnosis and early treatment of upper digestive tract cancer project in rural areas of Henan Province, the detection rate of the follow-up population is significantly higher than that of the primary screening population. Improving follow-up rate and paying more attention to the screening of people who need follow-up could further improve the screening effect.
