北京市2009年主要恶性肿瘤区域分布特征的研究

Study on the area distribution of malignant tumor in Beijing in 2009

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 area distribution of the primary malignant tumor in Beijing,including lung cancer,colorectal cancer,liver cancer,gastric cancer and breast cancer,so as to provide evidence for the control of malignant tumor. Methods The incidence rate of malignant tumor were collected in Beijing in 2009. Clustering analysis and correspondence analysis were applied to analyze the area distribution of malignant tumor. Correspondence analysis graph was made to analyze the area distribution of malignant tumor. Results The incidence rate of malignant tumor was different in the districts of Beijing; according to clustering analysis,the main malignant tumors in Beijing can be divided into 3 main distribution areas. Conclusion The incidence rate of malignant tumor was distributed geographically in Beijing and effective measures should be taken to control the prevalence of malignant tumor.
