Abstract
Background: Gastric cancer is the first most common cancer in men and third common cancer in women. In this study, we used space-time scan statistics to present geographical distribution model of gastric cancer and to detect high-risk cluster based on the gender.Methods: In this applied study, data reported by Iran cancer registry system broken by province level for the period of 2005-2009 were used. Space-time scan statistics was used to analyze the data and probable clusters were detected using sat scan software. In addition, ArcGIS10 was used to map the distribution of gastric cancer and to found clusters across the country.Findings: The most likely cluster that was significant for men included Ardabil, Guilan, Zanjan, East Azerbaijan, Qazvin, West Azerbaijan, Kurdistan, Hamadan, Tehran, and Mazandaran provinces during 2008-2009. For women, most likely cluster included Ardabil, Guilan, Zanjan, Qazvin, West Azerbaijan, Kurdistan, Hamadan, Tehran, Mazandaran, Qom, Semnan, and Markazi provinces.Conclusion: This study revealed similar distribution for gastric cancer in men and total population. For female population, the pattern is slightly different. Screening for early detection of gastric cancer in high-risk areas is recommended.
