“…In 2008, Mohebbi et al used the recorded data of cancer in the north of Iran and investigated the spatial patterns of the occurrence of gastric cancer. They found that gastric cancer in the southern coastline of the Caspian Sea has high-risk clusters and a regular geographic pattern (Mohebbi et al, 2008). In 2012, Asmarian et al used Poisson Kriging method and estimated the rate of gastric cancer regionally in all prevences of Iran.…”

“…Other authors go further and advise the comparison of results obtained by applying various methods at various scales in order to detect areas of activity in public health (Mohebbi et al, 2008). However, it should be remembered that the choice of the methods to be used depends in the end on the objectives of the study and the type of available data.…”

Cancer is a major concern among chronic diseases today. Spatial epidemiology plays a relevant role in this matter and we present here a review of this subject, including a discussion of the literature in terms of the level of geographic data aggregation, risk factors and methods used to analyse the spatial distribution of patterns and spatial clusters. For this purpose, we performed a websearch in the Pubmed and Web of Science databases including studies published between 1979 and 2015. We found 180 papers from 63 journals and noted that spatial epidemiology of cancer has been addressed with more emphasis during the last decade with research based on data mostly extracted from cancer registries and official mortality statistics. In general, the research questions present in the reviewed papers can be classified into three different sets: i) analysis of spatial distribution of cancer and/or its temporal evolution; ii) risk factors; iii) development of data analysis methods and/or evaluation of results obtained from application of existing methods. This review is expected to help promote research in this area through the identification of relevant knowledge gaps. Cancer's spatial epidemiology represents an important concern, mainly for public health policies design aimed to minimise the impact of chronic disease in specific populations. IntroductionGiven the relevance of spatial epidemiology in health research and the emphasis of cancer among chronic diseases, as well as the growing amount of studies in this area, it is important to know what the literature says about spatial epidemiology of cancer as well as provide its structured description. According to the World Health Organization (WHO), cancer is a leading cause of death in the world (WHO, 2015). It is also the cause of various morbidities and co-morbidities and can be responsible for loss of years of life years as well as loss of years without disability. Considering the aging population, it is predicted that the number of new cases of cancer will increase by more than 12% over the next decade in the European Union (EU) (DGS, 2013). The fight against cancer is a major challenge in public health. This challenge is due in part to the inequalities in terms of incidence, mortality, and survival. Therefore, a multidisciplinary approach is needed (Bastos et al., 2010). Among the various fields that can contribute to the development of knowledge about this disease, spatial epidemiology plays an important role. It can promote the understanding of spatial and temporal distribution patterns, helping to better identify the risk factors that influence them.Three types of approach can be established in spatial epidemiology: i) mapping; ii) geographic correlation; and iii) clustering (Elliott and Wartenberg, 2004). Mapping or map design regarding health and disease situations is the most often mentioned and used of these three approaches. Further, geographic correlation studies have the goal to spatially compare the health with several types of factors such as e...

“…Local indices results show the existence of significant clusters in the eastern and north eastern areas of the country, which are likely to imply the presence of common predisposing factors is in these areas. Although in some cases have good performance but is not a good null hypothesis for very systematic and complex system such as environment and the health sciences (4,12). However, up to this time except Goli et al study which determined spatial distribution of breast cancer with desired method in Fars province (13), there is not a national study that have explored significant clusters, or breast cancer pattern using geographical information system (GIS).…”

“…According to world health organization estimates, more than 508,000 people died in 2011 due to breast cancer and 58 % of deaths occur in less developed countries (3). Annually almost 90,000 new cases of cancer occur in the Iranian population (4) and cancer is the third most common cause of death after cardiovascular diseases and accidents (5,6).…”

Spatial Clustering of Breast Cancer: An Epidemiological Analysis of Iranian Women

Background: Breast cancer is the most common cancer among women in Iran. The aim of this study was to explore the spatial autocorrelation and the estimation incidence rates variance among Iranian provinces. Methods:In this cross-sectional exploratory study, age-standardized incidence rates from 2004 to 2010 were analyzed in order to detect hot and cold spots map and estimate the rates using ordinary kriging Conclusions:There are relatively large differences between the geographic distribution of the breast cancer clusters in the East and North East regions of the country in comparison to other areas. Policy makers are advised to consider such provincial diversity for better understanding of factors affecting the incidence of breast cancer.
