中文摘要: 摘 要：目的：分析2017—2021年通辽市居民消化系统恶性肿瘤的发病特征及变化趋势，为优化防控策略提供参考。 方法：利用2017—2021年通辽市居民消化系统恶性肿瘤监测数据以及人口资料，采用Excel 2020 、SPSS 20.0软件计算消化 系统恶性肿瘤粗发病率、中标率、发病顺位等指标，利用Joinpoint 回归模型估算年度变化百分比，以分析发病率的长期趋 势。结果：2017—2021年通辽市共报告消化系统恶性肿瘤15561例，占恶性肿瘤总发病例数的43.39%,发病顺位依次为食 管癌、肝癌、胃癌、结直肠癌、胰腺癌、胆囊癌和其他，其中前4位占消化系统肿瘤总发病例数的89.00%;男性和女性结 直肠癌和食管癌的发病顺位存在差异。年均粗发病率为110.2/10万，年均中标发病率为69.7/10万；男性粗发病率和标化发 病率均高于女性，差异有统计学意义 (x² 值分别为1077.70、92054.32,P<0.01); 城市粗发病率和标化发病率均高于 农村，差异有统计学意义 (x² 值分别为121.73、259693.70,P<0.01); 发病高峰集中在80~84岁年龄组；不同地区的 粗发病率和中标率差异有统计学意义 (x² 值分别为31.73、23.34,P<0.05) 。 结论：2017—2021年通辽市居民消化系统 主要的恶性肿瘤为食管癌、肝癌、胃癌、结直肠癌，总体发病无明显趋势变化，发病高峰在80~84岁，不同性别、地区的 发病率存在差异，应加强重点人群和重点癌种的防控。
Abstract:Abstract: OBJECTIVE To analyze the characteristics and trends of digestive system malignancies in Tongliao from,2017 to 2021, and to provide a scientific basis for evaluating prevention effectiveness and improving control measures.METHODS Monitoring data on digestive system malignancies among residents of Tongliao from 2017 to 2021,along with population data from the same period,were utilized.Excel 2020 and SPSS 20.0 were employed to calculate the crude incidence rate,age-standardizedincidence rate,and incidence ranking of digestive system malignancies.The Joinpoint software was used to compute the annual percentage change and analyze incidence trends.RESULTS From 2017 to 2021,a total of 15,561 cases of digestive system malignancies were reported in Tongliao City,accounting for 43.39%ofallmalignant tumors.The incidence ranking was as follows:esophageal cancer,liver cancer,gastric cancer,colorectal cancer,pancreatic cancer,gallbladder cancer,and others.The top four cancers constituted 89%of all digestive system malignancies. Differences in the incidence ranking of colorectal and esophageal cancers were observed between males and females.The average annual crude incidence rate was 110.2/100,000,and the average annual age-standardized incidence rate was 69.7/100,000.Both the crude and standardized incidence rates were higher in males than in females,and the difference was statistically significant(x²=1077.70,92054.32; P<0.01)and higher in urban areas than in rural areas,and the difference was statisically significant(x²=121.73,259693.70;P<0.01). The peak incidence occurred in the 80-84age group.Statistically significant ifferences in crude and age-standardized incidence rates were observed across different regions,and the difference was statistically significant(x²=31.73,23.34;P<0.05).CONCLUSION The primary digestive system malignancies in Tongliao City from 2017 to 2021 were esophageal cancer,liver cancer,gastric cancer,and colorectal cancer.No significant overall trend in incidence was observed,with the peak incidence occurring in the 80-84 age group. Differences in incidence were noted by gender and region,highlighting the need for enhanced prevention and control measures targeting key populations and specific cancer types.
