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 the spatial distribution of incidence of liver cancer in Guangxi and provide a scientific basis for the prevention and treatment of liver cancer. Methods Spatial scanning method was used to detect the distribution pattern of liver cancer in Guangxi region and to visualize the detection results by using geographic information system. Results The results of spatial scanning showed that the high prevalence of HCC in Guangxi was mainly located in the area with the center of 107.8152 ° and the latitude of 22.5677 ° and the radius of 78.53km (LLR = 997.661, RR = 4.918, P = 0.001) Gathered in the southwest of Guangxi. Conclusion Spatial scanning statistics can be used to detect the high incidence of disease area, and the size and location of the aggregation area to accurately locate for the prevention and treatment of liver cancer in Guangxi provide a scientific basis.
