【 摘 要 】

BackgroundAmong different common types of cancer, gastric cancer (GC) is a worldwide health priority in both developing and developed countries. The aim of this study was to map the distribution of incident cases of GC in Iran to provide a geographical presentation of the incidence of the disease.MethodsThis study used the Iranian National Cancer Registry (INCR) data from 2004 to 2014. We calculated the crude and age-standardized incidence rates of GC for each province and also defined the frequency distribution of different types and locations of GC by the provinces.ResultsAccording to the results of the present study, the patients were predominantly male 49,907 (70.0%) and the most prevalent type of tumour was A1 (almost 96.4%) and C3‌ (2.0%). Also, a significant difference was observed between males and females in the distribution of the types of tumour (P < 0.001). In addition, a comparison of the distribution of the types of GC in Iran suggested that a significant difference exists between the provinces (P < 0.001). A significant difference was observed when the distribution of the location of GC tumors was compared between males and females and provinces (P < 0.001). Accordingly, pylori and cardia are the most common location of GC cancer among the study population (28.1% and 31.3% respectively).ConclusionsThe results of the current study suggested a higher rate of GC incidence in Iran when compared to the global figure in both females and males. Our study also revealed significant disparities between provinces with regard to the distribution of types, and location of GC. This may suggest involving different factors in GC in different parts of Iran. Further studies are needed to better understand the epidemiology and etiology of the disease in Iran.
