title: Spatial distribution of liver cancer incidence in shenqiu county, henan province, china: a spatial analysis.
abstract: Liver cancer is a common and leading cause of cancer death in China. We used the cancer registry data collected from 2009 to 2011 to describe the spatial distribution of liver cancer incidence at village level in Shengqiu county, Henan province, China. Spatial autocorrelation analysis was employed to detect significant differences from a random spatial distribution of liver cancer incidence. Spatial scan statistics were used to detect and evaluate the clusters of liver cancer cases. Spatial clusters were mapped using ArcGIS 10.0 software in order to identify their physical location at village level. High cluster areas of liver cancer incidence were observed in 26 villages of 7 towns and low cluster areas were observed in 16 villages of 4 towns. High cluster areas of liver cancer incidence were distributed along the Sha Ying River which is the largest of tributary of the Huai River. Role of water pollution in Shenqiu County where the high cluster was found deserves further investigation.
