Spatial Clusters of Colorectal Neoplasm in the Center of Iran; a Population Based Study.
Spatial Clusters of Colorectal Neoplasm
,
Abstract
Background: By identifying the local foci and clusters of diseases, it can be hoped to reduce the incidence and deaths of the disease by making the necessary interventions. It was aimed to detect possible colorectal cancer incidence clusters using spatial analyses at point-level data at small census units in Arak, Iran from 2009 to 2014. Methods: In this ecologic study, recorded data on colorectal cancer in Arak have been collected from the Arak Cancer Registry. All records have been evaluated one-by-one using various methods to detect and resolve any probable error events or duplicated records. Then SaTScan software was used to explore spatial clusters. Discrete Poisson-based Probability Model was used to analyze the clusters. Results: 398 incidence cases of colorectal cancer was included. Three spatial clusters of colorectal cancer using individual geocodes were detected. The most high-risk cluster was located in the near of south highway of Arak, the highway with transit road of heavy and light vehicles(p=0.0004). The second significant high-risk cluster was a district located in the vast part of the center of Arak. The identified third high-risk cluster was an area in suburb of Arak, Proximity of Farmahin-Arak road and Northern highway. Conclusion: This study has identified three important clusters for the high incidence of colorectal cancer in Arak. Residents of these clusters need to be screened and trained to learn a healthy lifestyle. It is recommended that analytical studies at the individual level be designed and implemented to find the risk factors for colorectal cancer.
