Premature Mortality of Gastrointestinal Cancer in Iran: Trends and Projections for 2001–2030
Abstract Background: The aim of this study was to determine the trend and projection of premature mortality from gastrointestinal cancers (GI) at national and subnational levels in Iran.Methods: According to the data gathered through Iranian Death Registry System (DRS) and population data from census, mortality rate was calculated among 30-70 age group. The trends of premature mortality of esophageal, colon and rectum, gallbladder, pancreases, stomach, and liver cancers were estimated and projected at the national and subnational levels from 2001 to 2030. Spatio-temporal model was used to project spatial and temporal correlations. Results: The mortality rate of GI cancers in males was higher than females, indicating 6.1, 3.9 and 3.9 percent per 100000 in 2001, 2015 and 2030 respectively among males; whereas, the corresponding values for females were 3.8, 3.1 and 3.7 per 100000. The mortality rate of GI cancers had been decreasing by 2015 but it will remain stable by 2030 in males; however, the rate will be increasing in females. Also, there was a considerable variation in the mortality trends of different cancers. Pancreatic, gallbladder, and liver cancers were shown to have an increasing trend while a dropped was observed in the mortality of stomach, colon and rectum, and esophageal cancers. Conclusion: The difference in the patterns of GI cancers and their trends around the country showed that a more comprehensive control plan is needed that includes the predicted variations.
