Abstract: Objective The aim of this study was to analyze the epidemiological characteristics of gastrointestinal tumors in Yancheng city,Jiangsu province,evaluate the effect of gastrointestinal tumor prevention and control in recent years,and provide a basis for further development of gastrointestinal tumor prevention and control measures. Methods The whole population of Yancheng city′s death cause monitoring data and population data were collected from 2008 to 2018.The crude mortality of gastrointestinal tumors,standardized mortality,early death probability,annual percentage changes(APC)and other indicators were calculated by WHO recommended methods. Results From 2008 to 2018,the crude mortalities of esophageal cancer,stomach cancer and colorectal cancer were 19.00/100,000,18.10/100,000 and 4.22/100,000,respectively,accounting for 41.32% of total cancer deaths.The crude mortality,standardized mortality and early mortality of esophageal cancer showed a downward trend(APC=-1.49%,-4.97%,-6.39%,P＜0.01);the crude mortality,standardized mortality,and early mortality of stomach cancer also had downward trend(APC=-2.47%,-5.64%,-6.11%,P＜0.01).The crude mortality of colorectal cancer had an upward trend(APC=6.18,P＜0.01).The male standardized mortality and early mortality of colorectal cancer had upward trend(APC=4.08%,5.02%,P＜0.01),and there was no statistically change in the female for standardized mortality and early mortality(P＞0.05). Conclusion The mortality of gastrointestinal tumors in Yancheng city from 2008 to 2018 was relatively high.The deaths of stomach cancer and esophageal cancer show a downward trend,and male colorectal cancer shows a significant upward trend.Comprehensive prevention and control measures such as early diagnosis and treatment should be further strengthened.
