2019年内蒙古自治区肿瘤登记地区恶性肿瘤发病与死亡情况及2015—2019年趋势分析

Cancer Incidence and Mortality in Registration Areas of Inner Mongolia Autonomous Region in 2019 and Trends from 2015 to 2019

[目的]分析内蒙古自治区肿瘤登记地区2019年恶性肿瘤流行现况及2015—2019年变化趋势。[方法]利用内蒙古2019年30个肿瘤登记处的汇总数据库,分性别、城乡、年龄别计算恶性肿瘤发病和死亡粗率、中国人口标化率(中标率)、累积率、顺位及构成等。采用Joinpoint回归模型分析2015—2019年恶性肿瘤变化趋势。[结果]2019年内蒙古自治区肿瘤登记地区恶性肿瘤粗发病率为272.18/10万,中标率为179.00/10万,男性粗发病率比女性高13.81%,农村粗发病率比城市高5.61%。发病顺位前5位为肺癌、女性乳腺癌、结直肠癌、肝癌和胃癌。恶性肿瘤粗死亡率为156.64/10万,中标率为101.26/10万,男性粗死亡率比女性高74.17%,农村粗死亡率略高于城市1.53%。死亡顺位前5位为肺癌、肝癌、胃癌、食管癌、结直肠癌。2015—2019年内蒙古恶性肿瘤中标死亡率呈显著下降趋势(AAPC=-2.74%,P=0.045)。[结论]中老年人群的肺癌、肝癌、消化道癌症仍是内蒙古肿瘤防治工作重点,同时,应密切关注结直肠癌、乳腺癌、甲状腺癌的增长势头。

[Purpose]To analyze the incidence and mortality of cancer in 2019 and trends from 2015 to 2019 in cancer registration areas of Inner Mongolia Autonomous Region.[Methods]The pooled database of 30 cancer registries in Inner Mongolia in 2019 were used.The crude incidence/mortality rates,age-standardized rates by Chinese standard population(ASIRC/ASMRC),cumulative rates and the rank of cancers were calculated and stratified by sex,area and age group,respectively.Trends of cancer incidence and mortality from 2015 to 2019 were estimated by Joinpoint regression model.[Results]In 2019,the crude incidence in cancer registration areas of Inner Mongolia Autonomous Region was 272.18/105,ASIRC was 179.00/105;and the incidence rate of males was 13.81%higher than that of females,the incidence rate in rural areas was 5.61%higher than that in urban areas.The top five cancers with high incidence were lung,female breast,colorectal,liver and stomach cancer.The crude mortality was 156.64/105,ASMRC was 101.26/105,with the mortality rate of males being 74.17%higher than that of females,and the mortality rate in rural areas being 1.53%higher than that in urban areas.The top five cancers with high mortality were lung,liver,stomach,esophageal and colorectal cancer.From 2015 to 2019,ASMRC in Inner Mongolia showed a significant downward trend(AAPC=-2.74%,P=0.045).[Conclusion]Lung,liver and digestive tract cancers in the middle-aged and elderly populations remain the focus of cancer prevention and control in Inner Mongolia,while the rising trends of colorectal,breast and thyroid cancers should be closely monitored.
