“…The bulk of evidence suggests the association between use of salt and salty foods (Marmot et al, 2005)with increase in gastric cancer. Besides, using fresh fruit especially citrus and vegetables (containing alliums and anti oxidant) (Matsuzaka et al, 2007;Bafandeh & Farhang, 2009),and fresh fish (Terry et al, 2001;Kim et al, 2004) have been mentioned by various studies as preventive factors of gastric cancer. Although the diet of Mediterranean and Middle Eastern countries include safe food like fresh vegetables and fish (Hossein, 2010), they have also turned to western foods and lifestyle in recent decades.…”

Objective: gastric cancer is the fourth most common cancer worldwide . While it is one of the most common cancers in Iran, there are only limited data regarding incidence trends in the country. This study is the first of its type to investigate trends across six geographical areas during 2000-2005 using cancer registry data. Materials and methods: The registered data for gastric cancer cases in National Cancer Registry System were extracted from the Ministry of Health and Medical Education, Center for Disease Control & Management, code C16. First, according to WHO population, the sex-standardized incidence rate in both sexes and then the trends of incidence rate during 2000-2005 were investigated separately for different geographical areas of the country. Results: the incidence rates of gastric cancer in Iran and its six geographical areas during 2000-2005 were increasing albeit with differences in their slopes. The overall incidence rate increased from 2.8 in 2000 to 9.1 per 100,000 persons per year in 2005, rising from 4.1 to 13.2 in men. The average six-year incidence of gastric cancer in the central and northwestern border of Caspian Sea was 7.8 per 100,000 persons per year, while it was 0.9 per 100,000 persons per year in the border of the Persian Gulf. Generally the incidence rate in men was higher than in women. Conclusion: Iran is one of the high-risk areas for gastric cancer. Increase in incidence might continue in the future partly because of improvement in cancer registry systems as well as increase in risk of this cancer.

“…A previous study reported an increasing trend for the incidence of stomach cancer in both males and females (20). Explanations for the increase in incidence include higher exposure to Helicobacter pylori (21), unhealthy diets, consumption of salty foods, and lower rates of consumption of fruits and fresh vegetables (22). Despite the gradual decline in the global mortality rates, stomach can-cer was a major cause of death in the present study for both males and females.…”

Background: It is important to be able to predict cancer incidence and mortality rates for planning and managing the risk factors. Objectives: The present study investigated the changes in the incidence and mortality rates of five most common cancers in Iran. Methods:The cancer incidence and mortality data were obtained from the national cancer and mortality registries. Five most common cancers in both men and women were selected. Changes in the incidence and mortality rates of the selected cancers in both sexes were estimated by age group, annual percent change (APC), and average APC (AAPC) and then graphically displayed. Results:The most common cancers (except skin cancer) were breast, colorectal, stomach, esophageal, and thyroid cancers in women and stomach, prostate, bladder, colorectal, and esophageal cancers in men, respectively. The AAPCs of all cancer incidence rates had increased by 11.9% in men and 11.6% in women from 2002 to 2010. Also, the mortality rates had enhanced by 0.4% and 0.1% per year in men and women from 2006 to 2011, respectively. The greatest APC was reported in prostate cancer. The rate had increased by 41.9% from 2002 to 2004, by 13.4% from 2004 to 2008, and slowly augmented by 3.9% from 2008 to 2010. In women, the greatest APC was observed in colorectal cancer; the rate had enhanced by 13.4% per year from 2002 to 2010. The greatest increase for age-standardized mortality and incidence in 2011 was attributed to gastric cancer (12.5% and 17.1% per 100,000 men, respectively). In women, the highest age-standardized mortality rate was related to gastric cancer at 6.9% per 100,000 women. The incidence and mortality patterns of colorectal and esophageal cancers in men and women were similar, although they were slightly higher in men than women. Conclusions: Overall, cancer incidence rates had increased in both sexes. Many factors were responsible, such as changes in lifestyle, environmental factors, increased life expectancy, improvements in the registration systems, and declining mortality rates due to early detection and treatment. The results of this study provided useful information for the prediction of changes in the incidence and mortality of cancer and subsequent design of cancer control programs in Iran.

“…In this regard, spatial analyses help to generate new hypotheses. However, it is also important that clusters associated with certain cumulative risks such as income, urbanization and dietary patterns or areas that require the targeted interventions can be found (Bafandeh & Farhang, 2009;Hao et al, 2011).…”

Geo-epidemiological reporting and spatial clustering of the 10 most prevalent cancers in Iran

Cancer is a problem of both global and local concern. We determined the geo-epidemiological and spatial distribution of the 10 most common cancers in Iran. We used the data of the Iranian Cancer Registry for the year 2014 analysing the prevalence of 112,131 registered cancer cases with the aim of detecting potential geographical underlying causes. The geographic distribution of cancers is reported as standardized incidence rates at the provincial level considering risk with respect to sex and age. A geographical information systems (GIS) approach based on Anselin Local Moran’s index method was used to map clusters and spatial autocorrelation patterns. The mean age of the patients was 55.6 (±17.8) and 61.7 (±18.2) for females and males, respectively, in the database which showed 46.1% (n=51,665) of all cases to be female. Analysis of the spatial distribution of cancers showed significant differences among the different provinces. Stomach and breast cancers were the most prevalent cancers in men and females, respectively. The highest incidence rates of stomach cancer were found in Ardabil and Zanjan provinces, with 48.38 and 48.08 per 100,000 population, respectively, while Tehran and Yazd provinces had the highest incidences of breast cancer, 51.0 and 47.5 per 100,000 population, respectively. Strong clustering patterns for stomach and breast cancers were identified in the north-western provinces and in Semnan Province, respectively. These patterns indicate a diversity of geo-epidemiological contributing factors to cancer incidence in Iran.
