目的探索北京市主要恶性肿瘤(包括肺癌、结直肠癌、肝癌、胃癌和乳腺癌)的地区分布特点,为恶性肿瘤的防控提供科学依据。方法收集北京市2009年主要恶性肿瘤的发病率监测资料,应用聚类分析和对应分析研究北京市主要恶性肿瘤的区域分布特征,制作对应分析图研究主要恶性肿瘤发生的地区分布。结果北京市各区县恶性肿瘤发病率不同;聚类分析树状图显示北京市主要恶性肿瘤的发生可分为3个主要分布区域。结论北京市主要恶性肿瘤具有一定的地域分布特点,相关部门应根据其空间分布特点制定相应的防控措施。
Objective To explore the regional distribution of major malignancies (including lung cancer, colorectal cancer, liver cancer, gastric cancer and breast cancer) in Beijing and to provide scientific evidence for the prevention and control of malignant tumors. Methods The data of the incidence of major malignant tumors in Beijing in 2009 were collected. Cluster analysis and corresponding analysis were conducted to study the regional distribution of major malignant tumors in Beijing. Corresponding analysis charts were made to study the regional distribution of major malignant tumors. Results The incidence of malignant tumors was different in all districts and counties in Beijing. Cluster analysis showed that the incidence of major malignant tumors in Beijing could be divided into three main distribution areas. Conclusion The main malignant tumors in Beijing have some geographical distribution characteristics, and relevant departments should formulate corresponding prevention and control measures according to their spatial distribution characteristics.
