摘要
目的探测广西肝癌发病率的空间分布规律,为肝癌防治提供科学依据。方法应用空间扫描统计方法对广西肝癌病例在全区范围内的空间分布格局进行探测,并结合地理信息系统实现探测结果的可视化。结果空间扫描统计表明广西肝癌高发区聚集在圆心为东经107.8152°、北纬22.5677°、半径为78.53km的区域内(LLR=997.661、RR=4.918、P=0.001);疾病专题图亦显示肝癌高发区聚集在桂西南。结论空间扫描统计可用于探测疾病的高发聚集区,并对聚集区大小和位置进行准确定位,为广西肝癌防治提供科学依据。
Objective To detect spatial pattern of liver cancer in Guangxi and look for scientific evidence for effective liver cancer control and intervention. Methods Spatial Scan Statistic was used to detect the regions with high morbidity in Guangxi; simultaneously, Geographic Informarion System（GIS） was also employed to visualize results of Cluster Detection Tests. Results Both spatial scan statistic and disease map show that the region with high morbidity was located in southwest of Guangxi （LLR =997. 661 ,RR =4. 918,P =0. 001 ）. The central coordinate of clustering region of liver cancer is 107. 8152°E,22. 5677°N, and the radius of clustering region is about 78.53km. Conclusion Spatial scan statistic can be used for detecting regions with high morbidity and offer information about location and space of clustering region, which provide scientific evidence for liver cancer control and prevention, in Guangxi.
