内蒙古人群大肠癌的发病趋势和特点

Trends of incidence and characteristics of colorectal cancer in the population in Inner Mongolia

目的:分析内蒙古自治区城市和农村大肠癌的发病趋势和特点.方法:根据全区肿瘤登记地区的2009-2013年大肠癌的发病数据库,覆盖总人口24706321人.肿瘤登记采用ICD-9和ICD-0-3编码.发病趋势分别应用变化百分比(percent change,PC)和年度变化百分比(annual percent change,APC)分析.结果:2009-2013年我区大肠癌粗发病率29.18/105,其中城市33.42/105,农村14.55/105.2009-2013年大肠癌发病上升16.82%,其中城市上升18.91%,农村上升10.84%.结论:内蒙古自治区农村大肠癌的发病低于城市,整体低于全国,男性多于女性,并且城市发病呈现上升趋势.

AIM： To analyze the incidence trends and characteristics of colorectal cancer in Inner Mongolia urban and rural areas. METHODS： According to colorectal cancer incidence database derived from Inner Mongolia tumor registries from 2009 to 2013, there were a total population of 24706321（including both urban and rural areas）. ICD-9 and ICD-0-3 were used in the registries. Incidence trends were analyzed using the percentage change and the annual percent change（APC）.RESULTS： From 2009 to 2013, colorectal cancer incidence was 29.18/10^5 in Inner Mongolia, with 33.42/10^5 and 14.55/10^5 observed in urban and rural areas, respectively. The adjusted incidence rate in the Chinese standards was 22.98/10^5.From 2009 to 2013, colorectal cancer incidence increased by 18.93%（18.91% in urban areas and 10.84% in rural areas）.CONCLUSION： Colorectal cancer incidence rate in rural areas in China is lower than that in urban areas. An increasing incidence rate was observed in rural areas in contrast to the decreasing trend in urban areas.
